2012 JEEP GRAND CHEROKEE tow

WARNING!(Continued)
Does not predict the lane curvature or
the movement of preceding vehicles and
will not compensate for such changes.
Does not always fully recognize com-
plex driving conditions, which can result
in wrong or missing distance warnings.
Can only apply a maximum of 25% of
the vehicle’s braking capability, and will
not bring the vehicle to a complete stop.
WARNING!
You should switch off the ACC system:
• When driving in fog, heavy rain, heavy
snow, sleet, heavy traffic, and complex
driving situations (i.e., in highway construc-
tion zones).
• When entering a turn lane or highway off
ramp; when driving on roads that are wind-
ing, icy, snow-covered, slippery, or have
steep uphill or downhill slopes.
(Continued)
WARNING!(Continued)
• When towing a trailer up or down steep
slopes.
• When circumstances do not allow safe
driving at a constant speed.
Failure to follow these warnings can result in a
collision or serious personal injury.
The Cruise Control system has two control
modes:
• Adaptive Cruise Control mode for maintain-
ing an appropriate distance between ve-
hicles.
• Normal (fixed speed) cruise control mode for
cruising at a constant preset speed. For
additional information, refer to “Normal
(Fixed Speed) Cruise Control Mode” in this
section.
NOTE:
The system will not react to preceding ve-
hicles. Always be aware of the mode se-
lected. You can change the mode by using the Cruise
Control buttons. The two control modes func-
tion differently. Always confirm which mode is
selected.
Adaptive Cruise Control (ACC)

To keep the ACC System operating properly, it
is important to note the following maintenance
items:
•Always keep the sensor clean. Carefully
wipe the sensor lens with a soft cloth. Be
cautious not to damage the sensor lens.
• Do not remove any screws from the sensor.
Doing so could cause an ACC system mal-
function or failure and require a sensor re-
alignment.
• If the sensor is damaged due to a collision,
see your authorized dealer for service.
• Do not attach or install any accessories near
the sensor, including transparent material or
aftermarket grilles. Doing so could cause an
ACC system failure or malfunction.
When the condition that deactivated the system
is no longer present, the system will return to
the “Adaptive Cruise Control Off” state and will
resume function by simply reactivating it.
NOTE:
• If the “Clean Radar Sensor In Front Of
Vehicle” message occurs frequently (e.g.
more than once on every trip) without any snow, rain, mud, or other obstruction,
have the radar sensor realigned at your
authorized dealer.
• Installing a snow plow, front-end protec-
tor, an aftermarket grille or modifying the
grille is not recommended. Doing so may
block the sensor and inhibit ACC opera-
tion.
Removing ACC Sensor For Off-Roading
NOTE:
When off-roading, it may be advisable to
remove the ACC sensor. The sensor is lo-
cated behind the front lower grille in the
center of the vehicle. After removing the
lower fascia, you may remove the lower
sensor and bracket assembly.
To remove the sensor follow these instructions:
1. Unplug the connector by depressing the two
tabs on the connector and pulling it out. Do not
pull by the wiring or use any tools to remove the
connector.
2. Remove the wiring christmas tree attach-
ment from the back of the bracket. 3. Remove the two M6 fasteners that connect
the bracket to the bumper.
NOTE:
Do not change the adjustment fasteners or
pull the sensor off of the bracket. Doing so
may misalign the sensor.
Store the sensor and bracket assembly in a
safe location. The wiring and connector must
be stowed properly after the sensor and
bracket assembly is removed.
A connector plug is stowed on top of the
bumper beam. Insert the wiring connector into
the connector plug.
NOTE:
When the sensor is removed, Adaptive
Cruise Control, Normal Cruise Control, and
Forward Collision Warning will not be avail-
able. The cluster will display the warning
“ACC/FCW Unavailable - Service Radar Sen-
sor.”
To reinstall the sensor and bracket assembly
reverse the process above. The fastener torque
required to assembly the bracket back to the
beam is 6.6 ft lbs (9 Nm).

•Objects such as bicycle carriers, trailer
hitches, etc., must not be placed within
12 in (30 cm) from the rear fascia/bumper
while driving the vehicle. Failure to do so
can result in the system misinterpreting a
close object as a sensor problem, caus-
ing the “SERVICE PARK ASSIST SYS-
TEM” message to be displayed in the
instrument cluster.
• On vehicles equipped with a tailgate,
ParkSense should be disabled when the
tailgate is in the lowered or open position.
A lowered tailgate could provide a false
indication that an obstacle is behind the
vehicle.
CAUTION!
• ParkSense is only a parking aid and it is
unable to recognize every obstacle, includ-
ing small obstacles. Parking curbs might be
temporarily detected or not detected at all.
Obstacles located above or below the sen-
sors will not be detected when they are in
close proximity.
(Continued)
CAUTION!(Continued)
• The vehicle must be driven slowly when
using ParkSense in order to be able to
stop in time when an obstacle is detected.
When backing up, it is recommended that
the driver looks over his/her shoulder when
using ParkSense.
WARNING!
• Drivers must be careful when backing up
even when using the ParkSense Park
Assist System. Always check carefully be-
hind your vehicle, look behind you, and be
sure to check for pedestrians, animals,
other vehicles, obstructions, and blind
spots before backing up. You are respon-
sible for safety and must continue to pay
attention to your surroundings. Failure to
do so can result in serious injury or death.
(Continued)
WARNING!(Continued)
• Before using the ParkSense Park Assist
System, it is strongly recommended that
the ball mount and hitch ball assembly is
disconnected from the vehicle when the
vehicle is not used for towing. Failure to do
so can result in injury or damage to ve-
hicles or obstacles because the hitch ball
will be much closer to the obstacle than the
rear fascia when the warning display turns
on the single flashing arc and sounds the
continuous tone. Also, the sensors could
detect the ball mount and hitch ball assem-
bly, depending on its size and shape, giving
a false indication that an obstacle is behind
the vehicle.
PARKVIEW REAR BACK UP
CAMERA — IF EQUIPPED
Your vehicle may be equipped with the Park-
View Rear Back Up Camera that allows you to
see an on-screen image of the rear surround-
ings of your vehicle whenever the shift lever is
put into REVERSE. The image will be displayed

Closing Power Shade — Manual
Mode
To close the shade, press and hold the switch
in the forward position. Any release of the
switch will stop the movement and the shade
will remain in a partially closed condition until
the switch is pushed and held forward again.
Pinch Protect FeatureThis feature will detect an obstruction in the
opening of the sunroof during Express Close
operation. If an obstruction is detected, the
sunroof will automatically retract. Remove the
obstruction if this occurs. Next, press the
switch forward and release to Express Close.
NOTE:
If three consecutive sunroof close attempts
result in Pinch Protect reversals, the fourth
close attempt will be a Manual Close move-
ment with Pinch Protect disabled.
Pinch Protect OverrideIf a known obstruction (ice, debris, etc.) pre-
vents closing the sunroof, press the switch
forward and hold for two seconds after the
reversal occurs. This allows the sunroof to
move toward the closed position.NOTE:
Pinch protection is disabled while the
switch is pressed.
Wind BuffetingWind buffeting can be described as the per-
ception of pressure on the ears or a helicopter-
type sound in the ears. Your vehicle may exhibit
wind buffeting with the windows down, or the
sunroof (if equipped) in certain open or partially
open positions. This is a normal occurrence
and can be minimized. If the buffeting occurs
with the rear windows open, open the front and
rear windows together to minimize the buffet-
ing. If the buffeting occurs with the sunroof
open, adjust the sunroof opening to minimize
the buffeting or open any window.
Sunroof MaintenanceUse only a non-abrasive cleaner and a soft
cloth to clean the glass panel.
Ignition OFF OperationThe power sunroof switches can be pro-
grammed to remain active for up to approxi-
mately ten minutes after the ignition switch has
been turned OFF. Refer to “Electronic Vehicle
Information Center (EVIC)/Customer-Program-
mable Features (System Setup)” in “Under-
standing Your Instrument Panel” for further in-
formation.
NOTE:
Opening either front door will cancel this
feature.
Sunroof Fully ClosedPress the switch forward and release to ensure
that the sunroof is fully closed.
ELECTRICAL POWER OUTLETSYour vehicle is equipped with 12 Volt (13 Amp)
power outlets that can be used to power cellu-
lar phones, small electronics and other low
powered electrical accessories. The power out-
lets are labeled with either a “key” or a “battery”
symbol to indicate how the outlet is powered.
Power outlets labeled with a “key” are powered
when the ignition switch is in the ON or ACC
position, while the outlets labeled with a “bat-
tery” are connected directly to the battery and
powered at all times.

desired position, retighten the with the wrench
to lock the crossbar into position.
NOTE:
•To help control wind noise when the
crossbars are not in use, place the front
and rear crossbars approximately 24 in
(61 cm) apart. Optimal noise reduction
can then be achieved by adjusting the
front crossbar forward or aft using incre-
ments of 1 in (2.5 cm).
• If the rear crossbar (or any metallic ob-
ject) is placed over the satellite radio
antenna (if equipped), you may experi-
ence interruption of satellite radio recep-
tion. For improved satellite radio recep-
tion, avoid placing the rear crossbar over
the satellite radio antenna.
• The grab handles on the back of the
vehicle (if equipped) are not to be used as
a towing feature.CAUTION!
•To prevent damage to the roof of your
vehicle, do not carry any loads on the roof
rack without the crossbars installed. The
load should be secured and placed on top
of the crossbars, not directly on the roof. If
it is necessary to place the load on the roof,
place a blanket or some other protection
between the load and the roof surface.
• To avoid damage to the roof rack and
vehicle, do not exceed the maximum roof
rack load capacity of 150 lbs (68 kg).
Always distribute heavy loads as evenly as
possible and secure the load appropriately.
• Long loads which extend over the wind-
shield, such as wood panels or surfboards,
or loads with large frontal area should be
secured to both the front and rear of the
vehicle.
(Continued)CAUTION!(Continued)
• Travel at reduced speeds and turn corners
carefully when carrying large or heavy
loads on the roof rack. Wind forces, due to
natural causes or nearby truck traffic, can
add sudden upward lift to a load. This is
especially true on large flat loads and may
result in damage to the cargo or your
vehicle.
WARNING!
Cargo must be securely tied before driving
your vehicle. Improperly secured loads can fly
off the vehicle, particularly at high speeds,
resulting in personal injury or property dam-
age. Follow the roof rack cautions when car-
rying cargo on your roof rack.

INSTRUMENT CLUSTER
DESCRIPTIONS
1. Tachometer
Indicates the engine speed in revolutions per
minute (RPM x 1000).
2. Air Bag Warning LightThis light will turn on for four to
eight seconds as a bulb check
when the ignition switch is first
turned to the ON/RUN position. If
the light is either not on during
starting, stays on, or turns on while
driving, have the system inspected at an au-
thorized dealer as soon as possible. Refer to
“Occupant Restraints” in “Things To Know Be-
fore Starting Your Vehicle” for further informa-
tion.
3. Malfunction Indicator Light (MIL) The Malfunction Indicator Light (MIL)
is part of an onboard diagnostic sys-
tem called OBD II that monitors en-
gine and automatic transmission con-
trol systems. The light will illuminate
when the key is in the ON/RUN position before
engine start. If the bulb does not come on when turning the key from OFF to ON/RUN, have the
condition checked promptly.
Certain conditions, such as a loose or missing
gas cap, poor fuel quality, etc., may illuminate
the light after engine start. The vehicle should
be serviced if the light stays on through several
of your typical driving cycles. In most situa-
tions, the vehicle will drive normally and will not
require towing.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also
could affect fuel economy and drivability. If the
MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Im-
mediate service is required.
WARNING!
A malfunctioning catalytic converter, as refer-
enced above, can reach higher temperatures
than in normal operating conditions. This can
cause a fire if you drive slowly or park over
flammable substances such as dry plants,
wood, cardboard, etc. This could result in
death or serious injury to the driver, occupants
or others.
4. Electronic Stability Control (ESC)
Activation/Malfunction Indicator Light — If
Equipped The “ESC Activation/Malfunction
Indicator Light” in the instrument
cluster will come on when the igni-
tion switch is turned to the ON/
RUN position. It should go out with
the engine running. If the “ESC
Activation/Malfunction Indicator Light” comes
on continuously with the engine running, a
malfunction has been detected in the ESC
system. If this light remains on after several
ignition cycles, and the vehicle has been driven
several miles (kilometers) at speeds greater
159

than 30 mph (48 km/h), see your authorized
dealer as soon as possible to have the problem
diagnosed and corrected.
NOTE:
•The “ESC Off Indicator Light” and the
“ESC Activation/Malfunction Indicator
Light” come on momentarily each time
the ignition switch is turned to ON/RUN.
• Each time the ignition is turned to ON/
RUN, the ESC system will be ON, even if it
was turned off previously.
• The ESC system will make buzzing or
clicking sounds when it is active. This is
normal; the sounds will stop when ESC
becomes inactive following the maneuver
that caused the ESC activation.
5. TOW/HAUL Indicator Light — If
Equipped This light will illuminate when the
TOW/HAUL button has been se-
lected. The TOW/HAUL button is
located in the center of the instru-
ment panel (below the climate
controls). 6. Turn Signal Indicator
The arrows will flash with the exterior turn
signals when the turn signal lever is op-
erated. A tone will chime, and an EVIC
message will appear if the turn signals are left
on for more than 1 mile (1.6 km).
NOTE:
Check for an inoperative outside light bulb if
either indicator flashes at a rapid rate.
7. High Beam Indicator Indicates that headlights are on high
beam.
8. Front Fog Light Indicator — If Equipped This indicator will illuminate when the
front fog lights are on.
9. Hill Descent Control Indicator Light — If
Equipped The symbol indicates the status of
the Hill Decent Control (HDC) fea-
ture. The lamp will be on solid
when HDC is armed. HDC can
only be armed when the transfer
case is in the “4WD Low” position and the vehicle speed is less then 30 mph
(48 km/h). If these conditions are not met while
attempting to use the HDC feature, the HDC
indicator lamp will flash on/off.
10. Electronic Vehicle Information Center
(EVIC) Display/Odometer Display
The odometer display shows the total distance
the vehicle has been driven.
When the appropriate conditions exist, this
display shows the Electronic Vehicle Informa-
tion Center (EVIC) messages. Refer to “Elec-
tronic Vehicle Information Center”.
11. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recom-
mended by the vehicle manufac-
turer on the vehicle placard or tire
inflation pressure label. (If your vehicle has tires
of a different size than the size indicated on the
vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires.)
