2022 Chevrolet Silverado 1500 Starting and Operating

Starting and Operating

New Vehicle Break-In

Caution

The vehicle does not need an elaborate break-in. But it will perform better in the long run if you follow these guidelines:

• Do not drive at any one constant speed, fast or slow, for the first 800 km (500 mi). Do not make full-throttle starts. Avoid downshifting to brake or slow the vehicle.
• Avoid making hard stops for the first 300 km (200 mi) or so. During this time the new brake linings are not yet broken in. Hard stops with new linings can mean premature wear and earlier replacement. Follow this breaking-in guideline every time you get new brake linings.
• Do not tow a trailer during a break-in. See Trailer Towing 0 309 for the trailer towing capabilities of the vehicle and more information.

Following a break-in, engine speed and load can be gradually increased.

• On new vehicles, the various mechanical and electrical systems experience a “break-in” period during the first 6 400 km (4,000 mi) of routine driving. As the vehicle is driven, the mechanical systems adjust to provide optimal fuel economy and transmission shift performance.
• Electrical systems will adapt and calibrate during the break-in period. A one-time occurrence of clicks and similar vehicle noises is normal during this process.
• Normal driving charges the vehicle’s battery to achieve the best operation of the vehicle, including fuel economy and the Stop/Start System. See Stop/Start System 220.

Ignition Positions

• Vehicles equipped with Keyless Access have a pushbutton start.
• The remote key must be in the vehicle for the system to operate. If the pushbutton start is not working, the vehicle may be near a strong radio antenna signal causing interference to the Keyless Access system. See Remote Keyless Entry (RKE) System Operation  11.
• To shift out of P (Park), the vehicle must be on and the brake pedal must be applied.

Warning

Turning off the vehicle while moving may cause loss of power assist in the brake and steering systems and disable the airbags. While driving, only shut the vehicle off in an emergency.

Stopping the Engine/LOCK/OFF (No Indicator Lights) 

• When the vehicle is stopped, press ENGINE START/STOP once to turn the engine off.
• If the vehicle is in P (Park), the vehicle will turn off and Retained Accessory Power (RAP) will remain active. See Retained Accessory Power (RAP) 222.
• If the vehicle is not in P (Park), the vehicle will return to ACC/ACCESSORY and display the message SHIFT TO PARK in the Driver Information Center (DIC). When the vehicle is shifted into P (Park), the vehicle will turn off.
• The vehicle may have an electric steering column lock. The lock is activated when the ignition is turned off and the driver’s door is opened.
• A sound may be heard as the lock actuates or releases. The steering column lock may not release with the wheels turned off center.
• If this happens, the vehicle may not start. Move the steering wheel from left to right while attempting to start the vehicle. If this does not work, the vehicle needs service.
• Unless an emergency exists, do not turn the engine off when the vehicle is moving. This will cause a loss of power assist in the brake and steering systems and disable the airbags.

If the vehicle must be shut off in an emergency

1. If the vehicle cannot be pulled over and must be shut off while driving, press and hold the ENGINE START/STOP button for longer than two seconds, or press it twice in five seconds.
2. Brake using firm and steady pressure. Do not pump the brakes repeatedly. This may deplete power assist, requiring increased brake pedal force.
3. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving. After shifting to N (Neutral), firmly apply the brakes and steer the vehicle to a safe location.
4. Come to a complete stop, shift toP (Park), and make sure the engine is off. The shift lever must be in P (Park) to turn the vehicle off.
5. Set the parking brake. See Electric Parking Brake 242.

Warning

Turning off the vehicle while moving may cause loss of power assist in the brake and steering systems and disable the airbags. While driving, only shut the vehicle off in an emergency.

• ACC/ACCESSORY (Amber Indicator Light): This mode allows some electrical accessories to be used when the engine is off. With the vehicle off, pressing the ENGINESTART/STOP button one time without the brake pedal applied will place the vehicle in ACC/ACCESSORY. The vehicle will switch from ACC/ACCESSORY to off after five minutes to prevent battery rundown.
• ON/RUN/START (Green Indicator Light): This mode is for driving and starting. With the vehicle off, and the brake pedal applied, pressing the ENGINE START/STOP button once will turn the ignition on. Once engine cranking begins, release the button. Engine cranking will continue until the engine starts. See Starting the Engine 219.

Service Mode

This power mode is available for service and diagnostics, and to verify the proper operation of the malfunction indicator lamp as may be required for emission inspection purposes. With the vehicle off, and the brake pedal not applied, pressing andholding the ENGINE START/STOP button for more than five seconds will place the vehicle in Service Mode. The instruments and audio systems will operate as they do when the vehicle is on, but the vehicle will not be able to be driven. The engine will not start in Service Mode. Press the ENGINE START/STOP button again to turn the vehicle off.

Starting the Engine

If the vehicle has a diesel engine, see the Duramax diesel supplement.

Caution

If you add electrical parts or accessories, you could change the way the engine operates. Any resulting damage would not be covered by the vehicle warranty. See Add-On Electrical Equipment 0 334.

Move the shift lever to P (Park) or N (Neutral). To restart the engine when the vehicle is already moving, use N (Neutral) only.

Caution

Do not try to shift to P (Park) if the vehicle is moving. If you do, you could damage the transmission. Shift to P (Park) only when the vehicle is stopped.

Starting Procedure

1. The remote key must be in the vehicle. Press ENGINE START/STOP with the brake pedal applied. When the engine begins cranking, let go of the button. The driver may observe a minor, and temporary, brake pedal kickback when starting the vehicle. This is normal.
   1. The idle speed will go down as the engine gets warm. Do not race the engine immediately after starting it.
   2. Operate the engine and transmission gently to allow the oil to warm up and lubricate all moving parts.
   3. When the low fuel warning light is on and the FUEL LEVEL LOW message is displayed in the Driver Information Center (DIC), press ENGINE START/STOP to continue engine cranking.
2. Caution: Cranking the engine for long periods of time, by returning the ignition to the START position immediately after cranking has ended, can overheat and damage the cranking motor, and drain the battery. Wait at least 15 seconds between each try, to let the cranking motor cool down.
3. If the engine does not start after five to 10 seconds, especially in very cold weather (below −18 °C or 0 °F), it could be flooded with too much gasoline. Try pushing the accelerator pedal all the way to the floor and holding it there while pressing ENGINE START/STOP for up to a maximum of 15 seconds. Wait at least 15 seconds between each try, to allow the cranking motor to cool down. When the engine starts, let go of the button and accelerator. If the vehicle starts briefly but then stops again, do the same thing. This clears the extra gasoline from the engine. Do not race the engine immediately after starting it. Operate the engine and transmission gently until the oil warms up and lubricates all moving parts.

Stop/Start System

If equipped and enabled, the Stop/Start system will shut off the engine to help conserve fuel. It has components designed for an increased number of starts.

Warning

The automatic engine Stop/Start feature causes the engine to shut off while the vehicle is still on. Do not exit the vehicle before shifting to P (Park). The vehicle may restart and move unexpectedly. Always shift to P (Park), and then turn the ignition off before exiting the vehicle.

Auto Engine Stop/Start

When the brakes are applied and the vehicle is at a complete stop, the engine may turn off. When stopped, the tachometer displaysAUTO STOP. See Tachometer 0 108. When the brake pedal is released or the accelerator pedal is pressed, the engine will restart.

To maintain vehicle performance, other conditions may cause the engine to automatically restart before the brake pedal is released. Auto Stops may not occur and/or Auto Starts may occur because:

• The climate control settings require the engine to be running to cool or heat the vehicle interior.
• The vehicle battery needs to charge.
• The vehicle battery has recently been disconnected.
• Minimum vehicle speed has not been reached since the last Auto Stop.
• The accelerator pedal is pressed.
• The engine or transmission is not at the required operating temperature.
• The outside temperature is not in the required operating range.
• The vehicle is shifted out of D (Drive) to any gear other than P (Park).
• Certain driver modes have been selected. See Driver Mode Control 0 246 and Four-Wheel Drive 236.
• The vehicle is on a steep hill or grade.
• The driver’s door has been opened or the driver seat belt has been unbuckled.
• The hood has been opened.
• The Auto Stop has reached the maximum allowed time.

Auto Stop Disable Switch

• The automatic engine Stop/Start feature can be disabled and enabled by pressing h. Auto Stop/Start is enabled each time you start the vehicle.
• When the indicator is illuminated, the system is enabled.

Engine Heater

If equipped, the engine heater can provide easier starting and better fuel economy during engine warm-up in cold weather conditions at or below −18 °C (0 °F). Vehicles with an engine heater should be plugged in at least four hours before starting. An internal thermostat in the plug-end of the cord may exist, which will prevent engine heater operation at temperatures above −18 °C (0 °F).

Warning

Do not plug in the engine block heater while the vehicle is parked in a garage or under a carport. Property damage or personal injury may result. Always park the vehicle in a clear open area away from buildings or structures.

To Use the Engine Heater

1. Turn off the engine.
2. Check the heater cord for damage. If it is damaged, do not use it. See your dealer for a replacement. Inspect the cord for damage yearly.
3. Plug the heater cord into the connector on the vehicle.
4. Plug the cord into a grounded 110-volt AC outlet that is protected by a ground fault detection function.
5. Before starting the engine, be sure to unplug and store the cord.

Warning

Improper use of the heater cord or an extension cord can damage the cord and may result in overheating and fire.

• Plug the cord into a three-prong electrical utility receptacle that is protected by a ground fault detection function. An ungrounded outlet could cause an electric shock.
• Use a weatherproof, heavy-duty, 15 amp-rated extension cord if needed. Failure to use the recommended extension cord in good operating condition, or using a damaged heater or extension cord, could make it overheat and cause a fire, property damage, electric shock, and injury.
• Do not operate the vehicle with the heater cord permanently attached to the vehicle. Possible heater cord and thermostat damage could occur.
• While in use, do not let the heater cord touch vehicle parts or sharp edges. Never close the hood on the heater cord.
• Before starting the vehicle, unplug the cord, reattach the cover to the plug, and securely fasten the cord. Keep the cord away from any moving parts

The length of time the heater should remain plugged in depends on several factors. Ask a dealer in the area where you will be parking the vehicle for the best advice on this.

Shifting Into Park (Mechanical Shifter)

Warning

It can be dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, use the steps that follow. With four-wheel drive, if the transfer case is in N (Neutral), the vehicle will be free toroll, even if the shift lever is in P (Park). Be sure the transfer case is in a drive gear. If towing a trailer, see Driving Characteristics and Towing Tips 0 305.

1. Hold the brake pedal down, then set the parking brake. See Electric Parking Brake 242.
2. Move the shift lever into P (Park) by pulling the shift lever toward you and moving it up as far as it will go.
3. Be sure the transfer case, if equipped, is in a drive gear, not in N (Neutral).
4. Turn the vehicle off.
5. Take the remote key with you.

Leaving the Vehicle with the Engine Running

Warning: It can be dangerous to leave the vehicle with the engine running. The vehicle could move suddenly if the shift lever is not fully in P (Park) with the parking brake firmly set. If you have a four-wheel drive and the transfer case is in N (Neutral), the vehicle will be free to roll, even if the shift lever is in P (Park). So be sure the transfer case is in a drive gear – not in N (Neutral). And, if you leave the vehicle with the engine running, it could overheat and even catch fire. You or others could be injured. Do not leave the vehicle with the engine running unless you have to.

If you have to leave the vehicle with the engine running, be sure the vehicle is in P (Park) and the parking brake is firmly set before you leave it. After moving the shift lever into P (Park), hold the regular brake pedal down. Then, see if you can move the shift lever away from P (Park) without first pulling it toward you. If you can, it means that the shift lever was not fully locked into P (Park).

Torque Lock

• If you are parking on a hill and you do not shift the transmission into P (Park) properly, the weight of the vehicle may put too much force on the parking pawl in the transmission. You may find it difficult to pull the shift lever out of P (Park). This is called torque lock. To prevent torque lock, set the parking brake and then shift into P (Park) properly before you leave the driver’s seat.
• When you are ready to drive, move the shift lever out of P (Park) before you release the parking brake.
• If torque lock does occur, you may need to have another vehicle push yours a little uphill to take some of the pressure from the parking pawl in the transmission. You will then be able to pull the shift lever out of P (Park).

Shifting Into Park (Electronic Shifter)

Warning

It can be dangerous to get out of thevehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll. If you have left the engine running, the vehicle can move suddenly. You or others could be injured.To be sure the vehicle will not move, even when you are on fairly level ground, use the steps that follow. With four-wheel drive, if the transfer case is in (Neutral), the vehicle will be free to roll, even if the shift lever is in P (Park). Be sure the transfer case is in a drive gear. If towing a trailer, see Driving Characteristics and Towing Tips 305.

1. Hold the brake pedal down and set the parking brake. See Electric Parking Brake 242.

If the vehicle is shifted into P (Park) on a hill, the Electric Parking Brake (EPB) may apply automatically. The driver may not be able to release the EPB using the EPB switch. It should automatically release when the vehicle is shifted out of P (Park).

Leaving the Vehicle with the Engine Running

It can be dangerous to leave the vehicle with the engine running. It could overheat and catch fire. It is dangerous to get out of the vehicle if the vehicle is not in P (Park) with the parking brake set. The vehicle can roll. Do not leave the vehicle when the engine is running. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, always set the parking brake and shift to P (Park). See Shifting Into Park (Mechanical Shifter) 0 222 or  Shifting Into Park (Electronic Shifter)0 223. If you are towing a trailer, see Driving Characteristics and Towing Tips 0 305.

Shifting out of Park (Mechanical Shifter)

This vehicle is equipped with an electronic shift lock release system. The system is designed to prevent movement of the shift lever out of P (Park), unless the brake pedalis applied and the ignition is on or inService Mode. The shift lock release is always functional except in the case of an uncharged or low-voltage – less than 9 volt – battery. If the vehicle has an uncharged or low voltage battery, try charging or jump-starting the battery. See Jump Starting – North America 404.

6. After releasing the shift lever, it will return to the center position.

If the vehicle cannot shift from P (Park), a Driver Information Center (DIC) message may be displayed. Ensure the engine is running, the brake pedal is applied, and the shift lock release button is pressed whenyou are attempting to shift out of P (Park). If all of these conditions are met but the vehicle will not shift out of P (Park), see your dealer for service

Parking over Things That Burn

Warning: Things that can burn could touch hot exhaust parts under the vehicle and ignite. Do not park over papers, leaves, dry grass, or other things that can burn.

Active Fuel Management

If equipped, Active Fuel Management allows a V8, V6, or L4 gasoline engine to operate on either all of its cylinders or a reduced number of cylinders, depending on the driving conditions. When less power is required, such as cruising at a constant vehicle speed, the system will enable reduced cylinder operation, allowing the vehicle to achieve better fuel economy. When greater power is required, such as accelerating from a stop, passing, or merging onto a freeway, the system will maintain full-cylinder operation.

Dynamic Fuel Management

If equipped, Dynamic Fuel Management calculates the number of cylinders needed to maximize fuel economy and meet the driving demands. Dynamic Fuel Management allows the engine to operate in multiple possible configurations ranging from zero-cylinder up to the full 8-cylinder operation.

Extended Parking

• It is best not to park with the vehicle running. If the vehicle is left running, be sure it will not move and there is adequate ventilation.
• See Shifting Into Park (Mechanical Shifter) 222 or Shifting Into Park (Electronic Shifter) 223 and Engine Exhaust 225.
• If the vehicle is left parked and running with the remote key outside the vehicle, it will continue to run for up to 15 minutes.
• If the vehicle is left parked and running with the remote key inside the vehicle, it will continue to run for up to 30 minutes.
• The vehicle could turn off sooner if it is parked on a hill, due to a lack of available fuel.
• The timer will reset if the vehicle is taken out of P (Park) while it is running.
• When the vehicle was produced, it came with the auto-shutdown feature enabled.
• If you are not the primary owner of your vehicle, please note that this feature may have been disabled by a previous owner.
