2010 JEEP GRAND CHEROKEE spare tire

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. 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.
The “TPM Telltale Light” will also flash on and
off for 75 seconds and then remain on, and the
EVIC will display a
SERVICE TPM SYSTEM 
message when a system fault is detected pos-
sibly related to an incorrect sensor location
fault. In this case, the SERVICE TPM SYSTEM 
message is then followed by a graphic display,
with pressure values still shown. This indicates
the pressure values are still being received
from the TPM Sensors. However, the system
still needs to be serviced as long as the SER-
VICE TPM SYSTEM message exists.
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, the TPM Telltale Light 
238

will turn on, and the EVIC will still display a
Low Pressure message and a “flashing”
pressure value in the graphic display. After
driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), theTPM Telltale
Light will flash on and off for 75 seconds
and then remain on, the EVIC will display a
“SERVICE TPM SYSTEM message and then
display dashes (- -) in place of the pressure
value. For each subsequent ignition switch
cycle, a chime will sound, the TPM Telltale
Light will flash on and off for 75 seconds
and then remain on, the EVIC will display a
 SERVICE TPM SYSTEM message and then
display dashes (- -) in place of the pressure
value. Once you repair or replace the origi-
nal road tire, and reinstall it on the vehicle in
place of the spare tire, the TPMS will update
automatically.
In addition, the graphic in the EVIC will display
a new pressure value instead of dashes (- -), 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.TPMS DeactivationThe TPMS can be deactivated if replacing all
four wheel and tire assemblies (road tires) with
wheel and tire assemblies that do not have
TPMS Sensors, such as when installing winter
wheel and tire assemblies on your vehicle To
deactivate the TPMS, first, replace all four
wheel and tire assemblies (road tires) with tires
not equipped with Tire Pressure Monitoring
(TPM) Sensors. Then, drive the vehicle for
20 minutes above 24 km/h (15 mph). The TPMS
will chime, the TPM Telltale Light will flash on
and off for 75 seconds and then remain on and
the Electronic Vehicle Information Center
(EVIC) will display the “SERVICE TPM SYSTEM”
message and then display dashes (--) in place
of the pressure values. Beginning with the next
ignition switch cycle, the TPMS will no longer
chime or display the “SERVICE TPM SYSTEM”
message in the EVIC but dashes (--) will remain
in place of the pressure values.
To reactivate the TPMS, replace all four wheel
and tire assemblies (road tires) with tires
equipped with TPM sensors. Then, drive the
vehicle for up to 20 minutes above 24 km/h
(15 mph). The TPMS will chime, the TPM Telltale Light
will flash on and off for 75 sec-
onds and then turn off, and the Electronic
Vehicle Information Center (EVIC) will display
the “SERVICE TPM SYSTEM” message as long
as no system fault exists. The EVIC will also
display pressure values in place of the dashes,
on the next ignition switch cycle the SERVICE
TPM SYSTEM message will no longer be dis-
played as long as no system fault exists.

JACKING AND TIRE CHANGING
WARNING!
•Getting under a jacked-up vehicle is dan-
gerous. The vehicle could slip off the jack
and fall on you. You could be crushed.
Never get any part of your body under a
vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service
center where it can be raised on a lift.
• The jack is designed to be used as a tool
for changing tires only. The jack should not
be used to lift the vehicle for service pur-
poses. The vehicle should be jacked on a
firm, level surface only. Avoid ice or slippery
areas.
Jack LocationThe scissor-type jack and tire changing tools
are located in rear cargo area, below the load
floor.
Spare Tire StowageThe spare tire is stowed under the load floor in
the rear cargo area.
Preparations for Jacking
1. Park the vehicle on a firm, level surface.
Avoid ice or slippery surfaces.
WARNING!
Do not attempt to change a tire on the side of
the vehicle closest to moving traffic. Pull far
enough off the road to avoid being hit when
operating the jack or changing the wheel. 2. Turn on the Hazard Warning flasher.
3. Set the parking brake.
4. Place the shift lever into PARK.
5. Turn the ignition OFF.
6. Block both the front
and rear of the wheel
diagonally opposite of
the jacking position. For
example, if changing
the right front tire, block
the left rear wheel.
NOTE:
Passengers should not remain in the vehicle
when the vehicle is being jacked.
7. For vehicle equipped with Quadra-Lift refer
to “Quadra-Lift — If Equipped” in “Starting and
Operating” for further information on disabling
automatic leveling.

Jacking Instructions
WARNING!
Carefully follow these tire changing warnings
to help prevent personal injury or damage to
your vehicle:
•Always park on a firm, level surface as far
from the edge of the roadway as possible
before raising the vehicle.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the
wheel to be raised.
• Set the parking brake firmly and set an
automatic transmission in PARK.
• Never start or run the engine with the
vehicle on a jack.
• Do not let anyone sit in the vehicle when it
is on a jack.
• Do not get under the vehicle when it is on a
jack.
• Only use the jack in the positions indicated
and for lifting this vehicle during a tire
change.
(Continued)
WARNING!(Continued)
• If working on or near a roadway, be ex-
tremely careful of motor traffic.
• To assure that spare tires, flat or inflated,
are securely stowed, spares must be
stowed with the valve stem facing the
ground.
1. Remove the spare tire, jack, and tools from
storage.
2. Loosen (but do not remove) the wheel lug
nuts by turning them to the left, one turn, while
the wheel is still on the ground.
3. Assemble the jack and jacking tools. 4. For a front tire, place the jack and protective
cap on the body flange just behind the front tire
(as indicated by the triangular lift point symbol
on the sill molding).
Do not raise the vehicle
until you are sure the jack is fully engaged.

5. For a rear tire, place the jack and protective
cap in the slot on the rear tie-down bracket, just
forward of the rear tire (as indicated by the
triangular lift point symbol on the sill molding).
Do not raise the vehicle until you are sure
the jack is fully engaged.6. Raise the vehicle by turning the jack screw
clockwise. Raise the vehicle only until the tire
just clears the surface and enough clearance is
obtained to install the spare tire. Minimum tire
lift provides maximum stability.
WARNING!
Raising the vehicle higher than necessary can
make the vehicle less stable. It could slip off
the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.7. Remove the lug nuts and wheel.
8. Position the spare wheel/tire on the vehicle
and install the lug nuts with the cone-shaped
end toward the wheel. Lightly tighten the nuts.
To avoid the risk of forcing the vehicle off the
jack, do not tighten the nuts fully until the
vehicle has been lowered.
9. Lower the vehicle by turning the jack screw
counterclockwise, and remove the jack and
wheel blocks.
10. Finish tightening the lug nuts. Push down
on the wrench while tightening for increased
leverage. Alternate nuts until each nut has
been tightened twice. The correct wheel nut
tightness is 95 ft lbs (130 N·m). If in doubt about
the correct tightness, have them checked with
a torque wrench by your authorized dealer or at
a service station.
11. Lower the jack to the fully closed position
and return it and the tools to the proper posi-
tions in the foam tray.

12. Securely store the road wheel and jack in
the cargo area.
13. Have the aluminum road wheel and tire
repaired as soon as possible and properly
secure the spare tire, jack and tool kit.
WARNING!
A loose tire or jack, thrown forward in a
collision or hard stop could endanger the
occupants of the vehicle. Always stow the jack
parts and the spare tire in the places provided.
JUMP-STARTINGIf your vehicle has a discharged battery it can
be jump-started using a set of jumper cables
and a battery in another vehicle or by using a
portable battery booster pack. Jump-starting
can be dangerous if done improperly so please
follow the procedures in this section carefully.
NOTE:
When using a portable battery booster pack
follow the manufacturer’s operating instruc-
tions and precautions.
CAUTION!
Do not use a portable battery booster pack or
any other booster source with a system volt-
age greater than 12 Volts or damage to the
battery, starter motor, alternator or electrical
system may occur.
WARNING!
Do not attempt jump-starting if the battery is
frozen. It could rupture or explode and cause
personal injury.
Preparations for Jump-StartThe battery in your vehicle is located under the
passenger’s front seat. There are remote loca-
tions located under the hood to assist in jump-
starting.
