engine JEEP GRAND CHEROKEE 2016 WK2 / 4.G Repair Manual

Four-Wheel Drive Models
The manufacturer recommends towing with all wheelsOFFthe ground. Acceptable
methods are to tow the vehicle on a flatbed or with one end of vehicle raised and the
opposite end on a towing dolly.
If flatbed equipment is not available, and the transfer case is operable, vehicles with
a two-speed transfer case may be towed (in the forward direction, with ALLwheels on
the ground), IFthe transfer case is in NEUTRAL (N) and the transmission is in PARK.
Refer to “Recreational Towing” in “Starting And Operating” in the Owner’s Manual
on the DVD for detailed instructions.
Vehicles equipped with a single-speed transfer case have no NEUTRAL position, and
therefore mustbe towed with all four wheels OFFthe ground.
CAUTION!
• Front or rear wheel lifts must not be used. Internal damage to the transmission
or transfer case will occur if a front or rear wheel lift is used when towing.
• Towing this vehicle in violation of the above requirements can cause severe
transmission and/or transfer case damage. Damage from improper towing is
not covered under the New Vehicle Limited Warranty.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it can often be moved using a
rocking motion. Turn the steering wheel right and left to clear the area around the
front wheels. Push and hold the lock button on the gear selector. Then shift back and
forth between DRIVE and REVERSE while gently pressing the accelerator.
NOTE:
Shifts between DRIVE and REVERSE can only be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmission remains in NEUTRAL for more than two
seconds, you must push the brake pedal to engage DRIVE or REVERSE.
Use the least amount of accelerator pedal pressure that will maintain the rocking
motion without spinning the wheels or racing the engine.
WHAT TO DO IN EMERGENCIES
214

NOTE:
Push the "ESC Off" switch (if necessary), to place the Electronic Stability Control
(ESC) system in "Partial Off" mode, before rocking the vehicle. Refer to “Electronic
Brake Control” in “Starting And Operating” in the Owners Manual on the DVD for
further information. Once the vehicle has been freed, push the "ESC Off" switch
again to restore "ESC On" mode.
CAUTION!
Racing the engine or spinning the wheels may lead to transmission overheating
and failure. Allow the engine to idle with the transmission in NEUTRAL for at least
one minute after every five rocking-motion cycles. This will minimize overheating
and reduce the risk of transmission failure during prolonged efforts to free a stuck
vehicle.
WARNING!
Fast spinning tires can be dangerous. Forces generated by excessive wheel speeds
may cause damage, or even failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle's wheels faster than 30 mph (48 km/h)
or for longer than 30 seconds continuously without stopping when you are stuck
and do not let anyone near a spinning wheel, no matter what the speed.
CAUTION!
• When “rocking” a stuck vehicle by shifting between DRIVE and REVERSE, donot spin the wheels faster than 15 mph (24 km/h), or drivetrain damage may
result.
• Revving the engine or spinning the wheels too fast may lead to transmission
overheating and failure. It can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmission shifting occurring).
