tailgate JEEP GRAND CHEROKEE 2012 Owner handbook (in English)

•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.

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.

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

CAUTION!
•It is essential when replacing the cables on
the battery that the positive cable is at-
tached to the positive post, and the nega-
tive cable is attached to the negative post.
Battery posts are marked (+) positive and
(-) negative and identified on the battery
case.
• If a “fast charger” is used while battery is in
the vehicle, disconnect both vehicle battery
cables before connecting the charger to the
battery. Do not use a “fast charger” to
provide starting voltage.
Air Conditioner MaintenanceFor best possible performance, your air condi-
tioner should be checked and serviced by an
authorized dealer at the start of each warm
season. This service should include cleaning of
the condenser fins and a performance test.
Drive belt condition should also be checked at
this time.
CAUTION!
Do not use chemical flushes in your air con-
ditioning system as the chemicals can dam-
age your air conditioning components. Such
damage is not covered by the New Vehicle
Limited Warranty.
WARNING!
•Use only refrigerants and compressor lubri-
cants approved by the manufacturer for
your air conditioning system. Some unap-
proved refrigerants are flammable and can
explode, injuring you. Other unapproved
refrigerants or lubricants can cause the
system to fail, requiring costly repairs.
• The air conditioning system contains refrig-
erant under high pressure. To avoid risk of
personal injury or damage to the system,
adding refrigerant or any repair requiring
lines to be disconnected should be done by
an experienced repairman. NOTE:
Use only manufacturer approved A/C Sys-
tem Sealers, Stop Leak Products, Seal Con-
ditioners, Compressor Oil, and Refrigerants.
Refrigerant Recovery And Recycling
R-134a Air Conditioning Refrigerant is a hydro-
fluorocarbon (HFC) that is endorsed by the
Environmental Protection Agency (EPA) and is
an ozone-saving product. However, the manu-
facturer recommends that air conditioning ser-
vice be performed by authorized dealers or
other service facilities using recovery and recy-
cling equipment.
Body LubricationLocks and all body pivot points, including such
items as seat tracks, door hinge pivot points
and rollers, liftgate, tailgate, sliding doors and
hood hinges, should be lubricated periodically
with a lithium based grease, such as MOPAR
Spray White Lube or equivalent to assure quiet,
easy operation and to protect against rust and
wear. Prior to the application of any lubricant,
the parts concerned should be wiped clean to
remove dust and grit; after lubricating excess
oil and grease should be removed. Particular
