2015 JEEP GRAND CHEROKEE ECO mode

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. 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 press 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.
NOTE:Press the#ESC Off#switch (if necessary), to place
the Electronic Stability Control (ESC) system in#Partial
Off#mode, before rocking the vehicle. Refer to “Elec-
tronic Brake Control” in “Starting And Operating” for
further information. Once the vehicle has been freed,
press 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 en-
gine 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.

WHAT TO DO IN EMERGENCIES 587

If the key fob is unavailable, or the vehicle’s battery is
discharged, refer to “Manual Park Release” in this section
for instructions on shifting the transmission out of PARK
for towing.
CAUTION!
•Do not use sling type equipment when towing.
Vehicle damage may occur.
•When securing the vehicle to a flat bed truck, do
not attach to front or rear suspension components.
Damage to your vehicle may result from improper
towing.
Two-Wheel Drive Models
The manufacturer recommends towing your vehicle with
all four wheelsOFFthe ground using a flatbed.
If flatbed equipment is not available, and the transmis-
sion is operable, the vehicle may be towed (with rear
wheels on the ground) under the following conditions:
•The transmission must be in NEUTRAL. Refer to
#Manual Park Release#in this section for instructions
on shifting the transmission to NEUTRAL when the
engine is off.
•The towing speed must not exceed 30 mph (48 km/h).
•The towing distance must not exceed 30 miles (48 km).
If the transmission is not operable, or the vehicle must be
towed faster than 30 mph (48 km/h) or farther than 30 miles
(48 km), tow with the rear wheelsOFFthe ground. Accept-
able methods are to tow the vehicle on a flatbed, or with the
front wheels raised and the rear wheels on a towing dolly, or
(when using a suitable steering wheel stabilizer to hold the
front wheels in the straight position) with the rear wheels
raised and the front wheels on the ground.

quirements can cause severe transmission damage.

der the New Vehicle Limited Warranty.
Four-Wheel Drive Models
The manufacturer recommends towing with all wheels
OFFthe 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, vehicleswith a two-speed transfer case
may be towed (in the forward direction, withALLwheels
on the ground),IFthe transfer case is in NEUTRAL (N)
and the transmission is inPARK. Refer to “Recreational
Towing” in “Starting And Operating” for detailed in-
structions.
Vehicles equipped with a single-speed transfer case have
no NEUTRAL position, and thereforemustbe towed
with all four wheelsOFFthe ground.
