four wheel drive JEEP GRAND CHEROKEE 2011 WK2 / 4.G Owners Manual

INTRODUCTION
Congratulations on selecting your new Chrysler Group
LLC vehicle. Be assured that it represents precision
workmanship, distinctive styling, and high quality - all
essentials that are traditional to our vehicles.
This is a specialized utility vehicle, it can go places and
perform tasks for which conventional two-wheel drive
enclosed vehicles were not intended. It handles and
maneuvers differently from many passenger cars both
on-road and off-road, so take time to become familiar
with your vehicle.
The two-wheel drive utility vehicle was designed for
on-road use only. It is not intended for off-road driving
or use in other severe conditions suited for a four-wheel
drive vehicle.
Before you start to drive this vehicle, read the Owner’s
Manual. Be sure you are familiar with all vehicle controls,
particularly those used for braking, steering, transmission,and transfer case shifting. Learn how your vehicle handles
on different road surfaces. Your driving skills will improve
with experience. When driving off-road or working the
vehicle, don’t overload the vehicle or expect the vehicle to
overcome the natural laws of physics. Always observe
federal, state, provincial and local laws wherever you
drive.
As with other vehicles of this type, failure to operate this
vehicle correctly may result in loss of control or a
collision. Refer to “On-Road/Off-Road Driving Tips” in
“Starting And Operating” for further information.
This Owner’s Manual has been prepared with the assis-
tance of service and engineering specialists to acquaint
you with the operation and maintenance of your vehicle.
It is supplemented by Warranty Information, and various
customer-oriented documents. Please take the time to
read these publications carefully. Following the instruc-
tions and recommendations in this manual will help
assure safe and enjoyable operation of your vehicle.

DRIVER MEMORY SEAT — IF EQUIPPED
Once programmed, the memory buttons 1 and 2 on the
driver’s door panel can be used to recall the driver’s seat,
driver’s outside mirror, adjustable steering wheel posi-
tion (if equipped), and the radio station preset settings.
Your Remote Keyless Entry (RKE) transmitters can also
be programmed to recall the same positions when the
UNLOCK button is pressed.Your vehicle is equipped with two RKE transmitters. One
or both RKE transmitters can be linked to either memory
position. The memory system can accommodate up to
four RKE transmitters, each one linked to either of the
two memory positions.

NOTE:If ACC is resumed or set with the ESC/TCS off,
ESC will automatically be re-engaged.
To Turn Off
The system will turn off and erase the set speed in
memory if:
•You push the ON/OFF button.

NOTE: You can resume ACC from a minimum of
20 mph (32 km/h).
WARNING!
The Resume function should only be used if traffic
and road conditions permit. Resuming a set speed
that is too high or too low for prevailing traffic and
road conditions could cause the vehicle to accelerate
or decelerate too sharply for safe operation. This
could cause a collision and/or serious injury.
Adaptive Cruise Control Cancelled
174 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•The Electronic Stability Control/Traction Control Sys-
tem (ESC/TCS) activates.
To Resume
Press the RES+button and then remove your foot from
the accelerator pedal. The EVIC will display the last set
speed.
To Turn Off
The system will turn off and erase the set speed in
memory if:

•You turn off the ignition.
•You engage Four-Wheel Drive Low.
If the Cruise Control system is turned off and reactivated,
the system will return to the last driver setting (ACC or
Normal Cruise Control).
Forward Collision Warning — If Equipped
Forward Collision Warning (FCW) warns the driver of a
potential collision with the vehicle in front of you and
prompts the driver to take action in order to avoid the
collision.
FCW monitors the information from the forward looking
sensor as well as the Electronic Brake Controller (EBC),
wheel speed sensors, i.e., to calculate a probable rear-end
collision. When the system determines that a rear-end
collision is probable a warning message (both audible
and visual) will be displayed on the EVIC. When the
system determines a collision with the vehicle in front of
you is no longer probable, the warning message will be
deactivated.

The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN posi-
tion.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
15. Anti-Lock Brake (ABS) Light This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON/RUN position and
may stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have
the light inspected by an authorized dealer.
16. 4 LOW
This light alerts the driver that the vehicle is in
the four-wheel drive LOW mode. The front and
rear driveshafts are mechanically locked to-
gether forcing the front and rear wheels to
rotate at the same speed. Low range provides a greater
gear reduction ratio to provide increased torque at the
wheels.
For further information on four-wheel drive operation
and proper use, refer to “Four-Wheel Drive Operation —
If Equipped” in “Starting And Operating”.
17. Speedometer
Indicates vehicle speed.
