key JEEP GRAND CHEROKEE 2012 Owner handbook (in English)

When parking on a hill, apply the parking brake
before placing the shift lever in PARK, other-
wise the load on the transmission locking
mechanism may make it difficult to move the
shift lever out of PARK. As an added precau-
tion, turn the front wheels toward the curb on a
downhill grade and away from the curb on an
uphill grade.
WARNING!
•Never use the PARK position as a substi-
tute for the parking brake. Always apply the
parking brake fully when parked to guard
against vehicle movement and possible
injury or damage.
• Your vehicle could move and injure you and
others if it is not completely in PARK.
Check by trying to move the shift lever
rearward (with the brake pedal released),
after you have placed it in PARK. Make
sure the transmission is in PARK before
leaving the vehicle.
(Continued)
WARNING!(Continued)
•It is dangerous to move the shift lever out of
PARK or NEUTRAL if the engine speed is
higher than idle speed. If your foot is not firmly
pressing the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You
could lose control of the vehicle and hit some-
one or something. Only shift into gear when
the engine is idling normally and when your
foot is firmly pressing the brake pedal.
• Unintended movement of a vehicle could
injure those in or near the vehicle. As with
all vehicles, you should never exit a vehicle
while the engine is running. Before exiting a
vehicle, always apply the parking brake,
shift the transmission into PARK, and re-
move the key fob. Once the key fob is
removed, the shift lever is locked in the
PARK position, securing the vehicle
against unwanted movement.
• When leaving the vehicle, always remove
the key fob and lock your vehicle.
(Continued)
WARNING!(Continued)
• Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
• Allowing children to be in a vehicle unat-
tended is dangerous for a number of rea-
sons. A child or others could be seriously or
fatally injured. Children should be warned
not to touch the parking brake, brake pedal
or the shift lever. Do not leave the key fob in
or near the vehicle, and do not leave Key-
less Enter-N-Go in the ACC or ON/RUN
mode. A child could operate power win-
dows, other controls, or move the vehicle.
CAUTION!
•Before moving the shift lever out of PARK,
you must turn the ignition switch from the
LOCK/OFF position to the ON/RUN posi-
tion, and also press the brake pedal. Oth-
erwise, damage to the shift lever could
result.

ELECTRONIC BRAKE CONTROL
SYSTEM
Your vehicle is equipped with an advanced
electronic brake control system that includes
the Anti-Lock Brake System (ABS), Traction
Control System (TCS), Brake Assist System
(BAS), Electronic Roll Mitigation (ERM), and
Electronic Stability Control (ESC). All five of
these systems work together to enhance ve-
hicle stability and control in various driving
conditions.
Also, your vehicle is equipped with Trailer Sway
Control (TSC), Hill Start Assist (HSA), Brake
Lock Differential (BLD), Ready Alert Braking,
Rain Brake Support and, if it has four-wheel
drive with the MP 3023 two-speed transfer
case, Hill Descent Control (HDC).
Anti-Lock Brake System (ABS)
This system aids the driver in maintaining ve-
hicle control under adverse braking conditions.
The system controls hydraulic brake pressure
to prevent wheel lock-up and help avoid skid-
ding on slippery surfaces during braking.

Towing Without The Ignition Key
Fob
Special care must be taken when the vehicle is
towed with the ignition in the LOCK/OFF posi-
tion. The only approved method of towing with-
out the ignition key is with a flatbed truck.
Proper towing equipment is necessary to pre-
vent damage to the vehicle.
Four-Wheel Drive VehiclesThe 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, the vehicle may be
towed (in the forward direction, with ALL
wheels on the ground), IFthe transfer case is in
NEUTRAL and the transmission is in PARK.
Refer to “Recreational Towing” in “Starting And
Operating” for detailed instructions.CAUTION!
• Front or rear wheel lifts should not be used.
Internal damage to the transmission or
transfer case will occur if a front or rear
wheel lift is used when towing.
• Failure to follow these towing methods can
cause severe damage to the transmission
and/or transfer case. Such damage is not
covered by the New Vehicle Limited War-
ranty.
