spare tire JEEP GRAND CHEROKEE 2012 Owner handbook (in English)

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 aSERVICE 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 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), 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. 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

JACKING AND TIRE CHANGING
WARNING!
•Do not attempt to change a tire on the side
of the vehicle close to moving traffic. Pull
far enough off the road to avoid the danger
of being hit when operating the jack or
changing the wheel.
• Being under a jacked-up vehicle is danger-
ous. The vehicle could slip off the jack and
fall on you. You could be crushed. Never
put 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.
• Never start or run the engine while the
vehicle is on a jack.
• 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 and is secured to the body
with a special wing nut.
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.

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.
(Continued)
WARNING!(Continued)
• 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.
• 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.
CAUTION!
Do not attempt to raise the vehicle by jacking
on locations other than those indicated in the
Jacking Instructions for this vehicle. 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.
CAUTION!
Do not attempt to raise vehicle by jacking on
locations other than those indicated in the
Jacking Instructions for this vehicle.Jack Warning Label

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.
CAUTION!
Be sure to mount the spare tire with the valve
stem facing outward. The vehicle could be
damaged if the spare tire is mounted incor-
rectly.
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the wheel nuts fully until
the vehicle has been lowered. Failure to follow
this warning may result in personal injury.
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 at the end of the handle for
increased leverage. Tighten the lug nuts in a
star pattern until each nut has been tightened
twice. The correct wheel nut tightness is 110 ft
lbs (150 N·m). If in doubt about the correct
tightness, have them checked with a torque
wrench by your authorized dealer or at a ser-
vice 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. Remove the small center cap and securely
store the road wheel in the cargo area.

13. Have the aluminum road wheel and tire
repaired as soon as possible, properly secure
the spare tire with the special wing nut torqued
to 3.7 ft-lbs (5 N·m), reinstall the jack and tool
kit foam tray, and latch the rear load floor cover.
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.
Have the deflated (flat) tire repaired or re-
placed immediately.
Road Tire Installation
1. Mount the road tire on the axle.
2. Install the remaining lug nuts with the cone
shaped end of the nut toward the wheel. Lightly
tighten the lug nuts.
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the wheel nuts fully until
the vehicle has been lowered. Failure to follow
this warning may result in personal injury.
3. Lower the vehicle to the ground by turning
the jack handle counterclockwise.
4. Finish tightening the lug nuts. Push down on
the wrench while at the end of the handle for
increased leverage. Tighten the lug nuts in a
star pattern until each nut has been tightened
twice. The correct tightness of each lug nut is
110 ft/lbs (150 N·m). If in doubt about the
correct tightness, have them checked with a
torque wrench by your authorized dealer or
service station. 5. After 25 miles (40 km) check the lug nut
torque with a torque wrench to ensure that all
lug nuts are properly seated against the wheel.
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.
