2022 Jeep Wrangler Starting The Engine User Manual

2022 Jeep Wrangler Starting The Engine (Gasoline Engine)

STARTING THE ENGINE — GASOLINE ENGINE (IF EQUIPPED)

Before starting your vehicle, adjust your seat, adjust both inside and outside mirrors, and fasten your seat belts.

WARNING

• When exiting the vehicle, always remove the key fob from the ignition and lock your vehicle.
• Never leave children alone in a vehicle, or with access to an unlocked vehicle.
• Allowing children to be in a vehicle unattended is dangerous for a number of reasons. A child or others could be seriously or fatally injured. Children should be warned not to touch the parking brake, brake pedal or the gear selector.
• Do not leave the key fob in or near the vehicle, or in a location accessible to children. A child could operate power windows, other controls, or move the vehicle.
• Do not leave children or animals inside parked vehicles in hot weather. Interior heat build-up may cause serious injury or death.

MANUAL TRANSMISSION — IF EQUIPPED

Apply the parking brake, place the gear selector in NEUTRAL, and press the clutch pedal before starting the vehicle. This vehicle is equipped with a clutch interlocking ignition system. It will not start unless the clutch pedal is pressed to the floor.

Four-Wheel Drive Models Only

In 4L mode, if the vehicle is stalled, the engine will start regardless of whether or not the clutch pedal is pressed to the floor. This feature enhances off-road performance by allowing the vehicle to start when in 4L without having to press the clutch pedal. The 4L Indicator Light will illuminate when the transfer case has been shifted into this mode.

AUTOMATIC TRANSMISSION — IF EQUIPPED

Start the vehicle with the gear selector in the PARK position (the vehicle can also be started in NEUTRAL). Apply the brake before shifting to any driving range.

NORMAL STARTING

To Turn On The Engine Using The ENGINE START/STOP Button

1. 1. The transmission must be in PARK or NEUTRAL.
   2. Press and hold the brake pedal while pushing the ENGINE START/STOP button once.
2. 3. The system takes over and attempts to start the vehicle. If the vehicle fails to start, the starter will disengage automatically after 10 seconds.
   4. If you wish to stop the cranking of the engine prior to the engine starts, push the button again.

NOTE

Normal starting of either a cold or a warm engine is obtained without pumping or pressing the accelerator pedal. To Turn Off The Engine Using The ENGINE START/STOP Button

1. Place the gear selector in PARK, then push and release the ENGINE START/STOP button.
2. The ignition will return to the OFF position.
3. If the gear selector is not in PARK (with the vehicle stopped) and the ENGINE START/STOP button is pushed once, the transmission will automatically select PARK and the engine will turn off while the ignition will remain in the ACC position (NOT the OFF position). Never leave a vehicle out of the PARK position, or it could roll.
4. If the gear selector is in NEUTRAL, and the vehicle speed is below 5 mph (8 km/h), pushing the START/STOP button once will turn the engine off. The ignition will remain in the ACC position.
5. If the vehicle speed is above 5 mph (8 km/h), the ENGINE START/STOP button must be held for two seconds (or three short pushes in a row) to turn the engine off. The ignition will remain in the ACC position (NOT the OFF position) if the engine is turned off when the transmission is not in PARK.

NOTE

The system will automatically time out and the ignition will cycle to the OFF position after 30 minutes of inactivity if the ignition is left in the ACC or RUN (engine not running) position and the transmission is in PARK.

ENGINE START/STOP Button Functions — With Driver’s Foot OFF The Brake Pedal (In PARK Or NEUTRAL Position)

The ENGINE START/STOP button operates similarly to an ignition switch. It has three positions: OFF, ACC, and RUN. To change the ignition positions without starting the vehicle and use the accessories, follow these steps:

• Start with the ignition in the OFF position.
• Push the ENGINE START/STOP button once to place the ignition to the ACC position (instrument cluster will display “ACC”).
• Push the ENGINE START/STOP button a second time to place the ignition to the RUN position (the instrument cluster will display “ON/RUN”).
• Push the ENGINE START/STOP button a third time to return the ignition to the OFF position (the instrument cluster will display “OFF”).

AUTOPARK

AutoPark is a supplemental feature to assist in placing the vehicle in PARK should the situations on the following pages occur. It is a backup system and should not be relied upon as the primary method by which the driver shifts the vehicle into PARK. The conditions under which AutoPark will engage are outlined on the following pages.

WARNING

• Driver inattention could lead to failure to place the vehicle in PARK. ALWAYS DO A VISUAL CHECK that your vehicle is in PARK by verifying that a solid (not blinking) “P” is indicated in the instrument cluster display and on the gear selector. If the “P” indicator is blinking, your vehicle is not in PARK. As an added precaution, always apply the parking brake when exiting the vehicle.
• AutoPark is a supplemental feature. It is not designed to replace the need to shift your vehicle into PARK. It is a backup system and should not be relied upon as the primary method by which the driver shifts the vehicle into PARK.

If the vehicle is not in PARK and the driver turns off the engine, the vehicle may AutoPark.

AutoPark will engage when all of these conditions are met:

• The vehicle is equipped with an 8-speed transmission
• Driver’s door is ajar or if the driver’s door is removed and the driver is not on the seat (seat pad sensor detects driver missing)
• The vehicle is not in PARK
• Vehicle speed is 1.2 mph (1.9 km/h) or less
• Ignition is switched from RUN to OFF

NOTE

For Keyless Enter ‘n Go™ equipped vehicles, the engine will turn off and the ignition switch will change to ACC position.

If the vehicle is not in PARK and the driver exits the vehicle with the engine running, the vehicle may AutoPark.

AutoPark will engage when all of these conditions are met:

• The vehicle is equipped with an 8-speed transmission
• Driver’s door is ajar or if the driver’s door is removed and the driver is not on the seat (seat pad sensor detects driver missing)
• The vehicle is not in PARK
• Vehicle speed is 1.2 mph (1.9 km/h) or less
• The driver’s seat belt is unbuckled
• The brake pedal is not pressed

The message “AutoPark Engaged Shift to P then Shift to Gear” will display in the instrument cluster.
NOTE: In some cases, the ParkSense graphic will be displayed in the instrument cluster. In these cases,  the gear selector must be returned to “P” to select the desired gear.

• If the driver shifts into PARK while moving, the vehicle may AutoPark.
• AutoPark will engage ONLY when the vehicle speed is 1.2 mph (1.9 km/h) or less.
• The message “Vehicle Speed is Too High to Shift to P” will be displayed in the instrument cluster if the vehicle speed is above 1.2 mph (1.9 km/h).

WARNING

If the vehicle speed is above 1.2 mph (1.9 km/h), the transmission will default to NEUTRAL until the vehicle speed drops below 1.2 mph (1.9 km/h). A vehicle left in the NEUTRAL position can roll. As an added precaution, always apply the parking brake when exiting the vehicle.

4L

• AutoPark will be disabled when operating the vehicle in 4L.
• The message “AutoPark Disabled” will be displayed in the instrument cluster.

Additional customer warnings will be given when both of these conditions are met

• The vehicle is not in PARK
• Driver’s door is ajar

The message “AutoPark Not Engaged” will be displayed in the instrument cluster. A warning chime will continue until you shift the vehicle into PARK or the driver’s door is closed.
ALWAYS DO A VISUAL CHECK that your vehicle is in PARK by looking for the “P” in the instrument cluster display and on the gear selector. As an added precaution, always apply the parking brake when exiting the vehicle.

EXTREME COLD WEATHER (BELOW –22°F OR −30°C)

To ensure reliability starting at these temperatures, the use of an externally powered electric engine block heater (available from an authorized dealer) is recommended.

EXTENDED PARK STARTING

NOTE: Extended Park condition occurs when the vehicle has not been started or driven for at least 30 days.

1. Install a battery charger or jumper cables to the battery to ensure a full battery charge during the crank cycle.
2. Place the ignition in the START position and release it when the engine starts.
3. If the engine fails to start within 10 seconds, place the ignition in the OFF position, wait 10 to 15 seconds to allow the starter to cool, then repeat the “Extended Park Starting” procedure.
4. If the engine fails to start after eight attempts, allow the starter to cool for at least
   10 minutes, then repeat the procedure.

CAUTION

To prevent damage to the starter, do not crank continuously for more than 10 seconds at a time. Wait for 10 to 15 seconds before trying again.

IF THE ENGINE FAILS TO START

If the engine fails to start after you have followed the “Normal Starting” or “Extreme Cold Weather” procedure, and the vehicle has not experienced an extended park condition, it may be flooded. Push the accelerator pedal all the way to the floor and hold it there. Crank the engine for no more than 10 to 15 seconds. This should clear any excess fuel in case the engine is flooded. Leave the ignition in the RUN position, release the accelerator pedal and repeat the “Normal Starting” procedure.

WARNING

• Never pour fuel or other flammable liquid into the throttle body air inlet opening in an attempt to start the vehicle. This could result in a flash fire causing serious personal injury.
• Do not attempt to push or tow your vehicle to get it started. Vehicles equipped with an automatic transmission cannot be started this way. Unburned fuel could enter the catalytic converter and once the engine has started, ignite and damage the converter and vehicle.
• If the vehicle has a discharged battery, booster cables may be used to obtain a start from a booster battery or the battery in another vehicle. This type of start can be dangerous if done improperly page 338.

CAUTION

To prevent damage to the starter, do not continuously crank the engine for more than 10 to 15 seconds at a time. Wait for 10 to 15 seconds before trying again.

AFTER STARTING

The idle speed is controlled automatically and will decrease as the engine warms up.
