2022 Jeep Grand Cherokee Engine Starting
STARTING THE ENGINE
Before starting your vehicle, adjust your seat, adjust the inside and outside mirrors, fasten your seat belt, and if present, instruct all other occupants to buckle their seat belts.
WARNING!
- Before exiting a vehicle, always come to a complete stop, then shift the automatic transmission into PARK and apply the parking brake.
- Always make sure the keyless ignition node is in the OFF position, key fob is removed from the vehicle, and the vehicle is locked.
- Never leave children alone in a vehicle, or with access to an unlocked vehicle. Leaving children 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, and do not leave the ignition of a vehicle equipped with Keyless Enter ‘n Go™ in the ON/RUN position. 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.
AUTOMATIC TRANSMISSION
The gear selector must be in the NEUTRAL (N) or PARK (P) position before you can start the engine. Apply the brakes before shifting into any driving gear.
CAUTION!
Damage to the transmission may occur if the following precautions are not observed:
- Do not shift from REVERSE (R), PARK, or NEUTRAL into any forward gear when the engine is above idle speed.
- Shift into PARK only after the vehicle has come to a complete stop.
- Shift into or out of REVERSE only after the vehicle has come to a complete stop and the engine is at idle speed.
- Before shifting into any gear, make sure your foot is firmly on the brake pedal.
KEYLESS ENTER ‘N GO™ — IGNITION
This feature allows the driver to operate the ignition switch with the push of a button, as long as the Remote Start/Keyless Enter ‘n Go™ key fob is in the passenger compartment.
NORMAL STARTING
To Turn On The Engine Using The ENGINE START/STOP Button
- The transmission must be in PARK (P).
- Press and hold the brake pedal while pushing the ENGINE START/STOP button once.
- The system takes over and attempts to start the vehicle. If the vehicle fails to start, the starter will disengage automatically after 10 seconds.
- If you wish to stop the cranking of the engine prior to the engine starting, push the ENGINE START/STOP button again.
To Turn Off The Engine Using The ENGINE START/STOP Button
- Place the gear selector in PARK, then push and release the ENGINE START/STOP button.
- The ignition will return to the OFF position.
- If the gear selector is not in PARK, the ENGINE START/STOP button must be held for two seconds or three short pushes in a row with the vehicle speed above 5 mph (8 km/h) before the engine will shut off. The ignition will remain in the ON/RUN position until the gear selector is in PARK and the button is pushed twice to the OFF position.
- If the gear selector is not in PARK and the ENGINE START/STOP button is pushed once with the vehicle speed above 5 mph (8 km/h), the instrument cluster will display a “Vehicle Not In Park” message and the engine will remain running. Never leave a vehicle out of the PARK position, or it could roll.
NOTE:
If the gear selector is not in PARK, and the ENGINE START/STOP button is pushed once with the vehicle speed below 5 mph (8 km/h), the engine will shut off and the ignition will remain in the ON/RUN position. If vehicle speed drops below 1.2 mph (1.9 km/h), the vehicle may AutoPark page 123.
ENGINE START/STOP Button Functions — With Driver’s Foot OFF The Brake Pedal (In PARK Or NEUTRAL Position)
The ENGINE START/STOP button operates similar to an ignition switch. It has three positions: OFF, ON/RUN, and START. To change the ignition positions without starting the vehicle and use the accessories, follow these directions:
- Start with the ignition in the OFF position.
- Push the ENGINE START/STOP button once to place the ignition in the ON/RUN position.
- Push the ENGINE START/STOP button a second time to return the ignition to the OFF position.
NOTE:
Only press one pedal at a time while driving the vehicle. Torque performance of the vehicle could be reduced if both pedals are pressed at the same time. If pressure is detected on both pedals simultaneously, a warning message will display in the instrument cluster page 95.
AUTOPARK
AutoPark is a supplemental feature to assist in placing the vehicle in PARK (P) 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:
- Vehicle is equipped with an 8-speed transmission
- Vehicle is not in PARK
- Vehicle speed is 1.2 mph (1.9 km/h) or less
NOTE:
For Keyless Enter ‘n Go™ equipped vehicles, the engine will turn off and the ignition switch will change to the ON/RUN position. After 30 minutes the ignition switches to OFF automatically, unless the driver turns the ignition switch OFF.
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:
- Vehicle is equipped with an 8-speed transmission
- Vehicle is not in PARK
- Vehicle speed is 1.2 mph (1.9 km/h) or less
- Driver’s seat belt is unbuckled
- Driver’s door is ajar
- 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 desired gear.
If the driver shifts into PARK while moving, the vehicle may AutoPark.
AutoPark will engage ONLY when 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 vehicle speed is above 1.2 mph (1.9 km/h).
WARNING!
If 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.
4WD LOW — If Equipped
AutoPark will be disabled when operating the vehicle in 4WD LOW.
The message “AutoPark Disabled” will be displayed in the instrument cluster.
Additional customer warnings will be given when both of these conditions are met:
- 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.
IF ENGINE FAILS TO START
If the engine fails to start after you have followed the “Normal Starting” procedure and has not experienced an extended park condition (i.e., parked for more than 30 days), it may be flooded. Push the accelerator pedal all the way to the floor and hold it there while the engine is cranking. This should clear any excess fuel in case the engine is flooded. The starter motor will engage automatically, run for 10 seconds, and then disengage. Once this occurs, release the accelerator pedal and brake pedal, wait 10 to 15 seconds, then 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 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 323.
CAUTION!
To prevent damage to the starter, do not continuously crank the engine for more than 10 seconds at a time. Wait for 10 to 15 seconds before trying again.
COLD WEATHER OPERATION (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.
AFTER STARTING
The idle speed is controlled automatically, and it will decrease as the engine warms up.
