JEEP GRAND CHEROKEE 2012 WK2 / 4.G Owners Manual

To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild soap solution fol-
lowed by rinsing.
Do not use abrasive cleaning components, solvents, steel
wool or other aggressive material to clean the lenses.
Glass Surfaces
All glass surfaces should be cleaned on a regular basis
with MOPARGlass Cleaner or any commercial
household-type glass cleaner. Never use an abrasive type
cleaner. Use caution when cleaning inside rear windows
equipped with electric defrosters. Do not use scrapers or
other sharp instruments which may scratch the elements.
When cleaning the rearview mirror, spray cleaner on the
towel or rag that you are using. Do not spray cleaner
directly on the mirror.
Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this vehicle are
molded in clear plastic. When cleaning the lenses, care
must be taken to avoid scratching the plastic.
1. Clean with a wet soft rag. A mild soap solution may be
used, but do not use high alcohol content or abrasive
cleaners. If soap is used, wipe clean with a clean damp
rag.
2. Dry with a soft cloth.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with chemical
solvents or abrasive cleaners. This will weaken the fabric.
Sun damage will also weaken the fabric.
If the belts need cleaning, use MOPAR Total Clean, a
mild soap solution, or lukewarm water. Do not remove
the belts from the vehicle to wash them. Dry with a soft
cloth.

CAUTION!
•When installing the totally integrated power mod-
ule cover, it is important to ensure the cover is
properly positioned and fully latched. Failure to
do so may allow water to get into the totally
integrated power module and possibly result in a
electrical system failure.

MAINTAINING YOUR VEHICLE 615

CAUTION! (Continued)
•When replacing a blown fuse, it is important to
use only a fuse having the correct amperage rating.
The use of a fuse with a rating other than indicated
may result in a dangerous electrical system over-
load. If a properly rated fuse continues to blow, it
indicates a problem in the circuit that must be
corrected.
VEHICLE STORAGE
If you are leaving your vehicle dormant for more than
21 days you may want to take steps to protect your
battery. You may:
•Remove fuse #J13 in the Totally Integrated Power
Module (TIPM) labeled Ignition-Off Draw (IOD#1).
•Or, disconnect the negative cable from the battery.
•Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.

If a bulb needs to be replaced, visit your authorized
dealer or refer to the applicable Service Manual.BULB REPLACEMENT
High Intensity Discharge Headlamps (HID) – If
Equipped
The headlamps are a type of high voltage discharge tube.
High voltage can remain in the circuit even with the
headlamp switch off and the key removed. Because of
this, you should not attempt to service a headlamp bulb
yourself. If a headlamp bulb fails, take your vehicle to
an authorized dealer for service.
WARNING!
A transient high voltage occurs at the bulb sockets of
High Intensity Discharge (HID) headlamps when the
headlamp switch is turned ON. It may cause serious
electrical shock or electrocution if not serviced prop-
erly. See your authorized dealer for service.

MAINTAINING YOUR VEHICLE 617

NOTE:On vehicles equipped with High Intensity Dis-
charge (HID) headlamps, when the headlamps are
turned on, there is a blue hue to the lamps. This dimin-
ishes and becomes more white after approximately
10 seconds, as the system charges.
Halogen Headlamps – If Equipped
1. Open the hood.
2. Turn the low or high beam bulb one–quarter turn
counterclockwise to remove from housing.
3. Disconnect the electrical connector and replace the
bulb.
CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If the
bulb comes in contact with any oily surface, clean the
bulb with rubbing alcohol.
Front Turn Signal
1. Open the hood.
2. Turn the turn signal bulb one–quarter turn counter-
clockwise to remove from housing.
3. Disconnect the electrical connector and replace the
bulb.
CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If the
bulb comes in contact with any oily surface, clean the
bulb with rubbing alcohol.
