2012 JEEP GRAND CHEROKEE window

will sound. If the ignition switch is cycled, this
sequence will repeat, providing the system
fault still exists. The “Tire Pressure Monitoring
Telltale Light” will turn off when the fault condi-
tion no longer exists. A system fault can occur
by any of the following:
1. Jamming due to electronic devices or driv-
ing next to facilities emitting the same Radio
Frequencies as the TPM sensors.
2. Installing some form of aftermarket window
tinting that affects radio wave signals.
3. Lots of snow or ice around the wheels or
wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM
sensors.
NOTE:
There is no tire pressure monitoring sensor
in the spare tire. The TPMS will not be able to
monitor the tire pressure. If you install the
spare tire, in place of a road tire, that has a
pressure below the low-pressure warning
limit, upon the next ignition switch cycle, a
chime will sound, a “TIRE LOW PRESSURE”message will be displayed in the instrument
cluster, and the “Tire Pressure Monitoring
Telltale Light” will turn ON. After driving the
vehicle for up to 20 minutes above 15 mph
(25 km/h), the “Tire Pressure Monitoring
Telltale Light” will flash on and off for
75 seconds and then remain on solid. In
addition, a “SERVICE TPM SYSTEM” mes-
sage will be displayed. For each subsequent
ignition switch cycle, a chime will sound, a
“SERVICE TPM SYSTEM” message will be
displayed, and the “Tire Pressure Monitor-
ing Telltale Light” will flash on and off for
75 seconds and then remain on solid. Once
you repair or replace the original road tire,
and reinstall it on the vehicle in place of the
spare tire, the TPMS will update automati-
cally and the “Tire Pressure Monitoring Tell-
tale Light” will turn OFF, as long as no tire
pressure is below the low-pressure warning
limit in any of the four active road tires. The
vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) in order
for the TPMS to receive this information.Premium System – If EquippedThe Tire Pressure Monitor System (TPMS) uses
wireless technology with wheel rim-mounted
electronic sensors to monitor tire pressure lev-
els. Sensors, mounted to each wheel as part of
the valve stem, transmit tire pressure readings
to the Receiver Module.
NOTE:
It is particularly important, for you to regu-
larly check the tire pressure in all of your
tires and to maintain the proper pressure.
The Tire Pressure Monitor System (TPMS) con-
sists of the following components:
•
Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light
• Various Tire Pressure Monitoring System
Messages, which display in the Electronic
Vehicle Information Center (EVIC), and a
graphic displaying tire pressures

Tire Pressure Monitoring Low Pressure
Warnings
When one or more of the four active road tire
pressures are low, the “TPM Telltale Light” will
illuminate, an audible chime will sound, the
EVIC will display “Low Tire Pressure” message
for a minimum of five seconds, and a graphic
display of the pressure value(s) with the low
tire(s) “flashing.” Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding
Your Instrument Panel” for further information.
NOTE:
Your system can be set to display pressure
units in PSI, kPa, or BAR.Should a low tire condition occur on any of the
four active road tire(s), you should stop as soon
as possible, and inflate the low tire(s) that is
“flashing” on the graphic display to the vehi-
cle’s recommended cold tire pressure. The
system will automatically update, the graphic
display of the pressure value(s) will stop “flash-
ing,” and the Low Pressure text message(s) will
switch off once the updated tire pressure(s)
have been received. The vehicle may need to
be driven for up to 20 minutes above 15 mph
(24 km/h) to receive this information.
SERVICE TPM SYSTEM Warning
When a system fault is detected, the “TPM
Telltale Light” will flash on and off for 75 sec-
onds then remain on solid, and a chime will
sound. The EVIC will display a “SERVICE TPM
SYSTEM” message. This message is then fol-
lowed by a graphic display, with “- -“ in place of
the pressure value(s), indicating which Tire
Pressure Monitoring Sensor(s) is not being re-
ceived.
NOTE:
Your system can be set to display pressure
units in PSI, kPa, or BAR.If the ignition switch is cycled, this sequence
will repeat, providing the system fault still ex-
ists. If the system fault no longer exists, the
“TPM Telltale Light” will no longer be illumi-
nated, the “SERVICE TPM SYSTEM
message
will not be present, and a pressure value will be
displayed instead of dashes. A system fault
can occur by any of the following:
1. Jamming due to electronic devices or driv-
ing next to facilities emitting the same Radio
Frequencies as the TPM sensors.
2. Installing some form of aftermarket window
tinting that affects radio wave signals.

Materials Added to Fuel
Besides using unleaded gasoline with the
proper octane rating, gasolines that contain
detergents, corrosion and stability additives
are recommended. Using gasolines that have
these additives will help improve fuel economy,
reduce emissions, and maintain vehicle perfor-
mance.
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these ma-
terials intended for gum and varnish removal
may contain active solvents or similar ingredi-
ents. These can harm fuel system gasket and
diaphragm materials.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to pre-
vent carbon monoxide poisoning:(Continued)
WARNING!(Continued)
• Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas which can kill. Never run the engine in
a closed area, such as a garage, and never
sit in a parked vehicle with the engine
running for an extended period. If the ve-
hicle is stopped in an open area with the
engine running for more than a short pe-
riod, adjust the ventilation system to force
fresh, outside air into the vehicle.
• Guard against carbon monoxide with
proper maintenance. Have the exhaust
system inspected every time the vehicle is
raised. Have any abnormal conditions re-
paired promptly. Until repaired, drive with
all side windows fully open.
• Keep the liftgate closed when driving your
vehicle to prevent carbon monoxide and
other poisonous exhaust gases from enter-
ing the vehicle.FUEL REQUIREMENTS — DIESEL
ENGINE
Use good quality diesel fuel from a reputable
supplier. For most year-round service, No. 2
diesel fuel, meeting ASTM specification D-975
Grade S15, will provide good performance. If
the vehicle is exposed to extreme cold (below
20° F or -7° C), or is required to operate at
colder-than-normal conditions for prolonged
periods, use climatized No. 2 diesel fuel or
dilute the No. 2 diesel fuel with 50% No. 1
diesel fuel. This will provide better protection
from fuel gelling or wax-plugging of the fuel
filters. This vehicle must only use premium
diesel fuel that meets the requirements of
EN 590. Biodiesel blends that meet EN 590
may also be used.
CAUTION!
The manufacturer requires that you must fuel
this vehicle with Ultra Low Sulfur Highway
Diesel fuel (15 ppm Sulfur maximum) and
prohibits the use of Low Sulfur Highway Die-
sel fuel (500 ppm Sulfur maximum) to avoid
damage to the emissions control system.

4. Install the wiper blade pivot pin into the
wiper blade holder at the end of the wiper arm,
and firmly press the wiper blade until it snaps
into place.
5. Lower the wiper blade and snap the pivot
cap into place.
Adding Washer FluidThe fluid reservoir for the windshield washers
and the rear window washer is shared. The fluid
reservoir is located in the engine compartment,
be sure to check the fluid level at regular
intervals. Fill the reservoir with windshield
washer solvent only (not radiator antifreeze).
When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or
towel and wipe clean the wiper blades, this will
help blade performance. To prevent freeze-up
of your windshield washer system in cold
weather, select a solution or mixture that meets
or exceeds the temperature range of your cli-
mate. This rating information can be found on
most washer fluid containers.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling
or working around the washer solution.
Exhaust SystemThe best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained engine exhaust system.
If you notice a change in the sound of the
exhaust system; or if the exhaust fumes can be
detected inside the vehicle; or when the under-
side or rear of the vehicle is damaged; have an
authorized technician inspect the complete ex-
haust system and adjacent body areas for
broken, damaged, deteriorated, or misposi-
tioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the
passenger compartment. In addition, inspect
the exhaust system each time the vehicle is
raised for lubrication or oil change. Replace as
required.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you uncon-
scious and can eventually poison you. To
avoid breathing CO, refer to “Safety Tips/
Exhaust Gas” in “Things To Do Before Starting
Your Vehicle” for further information.
CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will de-
stroy the effectiveness of the catalyst as an
emissions control device and may seriously
reduce engine performance and cause seri-
ous damage to the engine.
Under normal operating conditions, the cata-
lytic converter will not require maintenance.
However, it is important to keep the engine
properly tuned to assure proper catalyst opera-
tion and prevent possible catalyst damage.

Plastic is not as scratch-resistant as glass and
therefore different lens cleaning procedures
must be followed.
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 followed by rinsing.
Do not use abrasive cleaning components,
solvents, steel wool or other aggressive mate-
rial 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 cau-
tion 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.
Replace the belts if they appear frayed or worn
or if the buckles do not work properly.FUSES
Totally Integrated Power Module
The Totally Integrated Power Module is located
in the engine compartment. This center con-
tains cartridge fuses and mini fuses. A descrip-
tion of each fuse and component may be
stamped on the inside cover, otherwise the
cavity number of each fuse is stamped on the
inside cover that corresponds to the following
