2013 JEEP GRAND CHEROKEE spare tire

to the tread wear indicators, the temporary use full size
spare tire needs to be replaced. Since it is not the same as
your original equipment tire, replace (or repair) the
original equipment tire and reinstall on the vehicle at the
first opportunity.
Limited-Use Spare – If Equipped
The limited-use spare tire is for temporary emergency
use only. This tire is identified by a label located on the
limited-use spare wheel. This label contains the driving
limitations for this spare. This tire may look like the
original equipped tire on the front or rear axle of your
vehicle, but it is not. Installation of this limited-use spare
tire affects vehicle handling. Since it is not the same as
your original equipment tire, replace (or repair) the
original equipment tire and reinstall on the vehicle at the
first opportunity.
WARNING!
Limited-use spares are for emergency use only. In-
stallation of this limited-use spare tire affects vehicle
handling. With this tire, do not drive more than the
speed listed on the limit-use spare wheel. Keep
inflated to the cold tire inflation pressure listed on
your Tire and Loading Information Placard located
on the driver ’s side door opening. Replace (or repair)
the original equipment tire at the first opportunity
and reinstall it on your vehicle. Failure to do so could
result in loss of vehicle control.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle’s wheels above 30 mph (48 km/h) or
for longer than 30 seconds continuously without stop-
ping when you are stuck.
500 STARTING AND OPERATING

Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style
• Tire pressure
• Distance driven
• Performance tires, tires with a speed rating of V or
higher, and summer tires, typically have a reduced
tread life. Rotation of these tires per the vehicle main-
tenance schedule is highly recommended.
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have a collision resulting in
serious injury or death.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed. (Refer to the paragraph on
“Tread Wear Indicators”). Refer to the “Tire and Loading
Information” placard for the size designation of your tire.
The Load Index and Speed Symbol for your tire will be
found on the original equipment tire sidewall. See the
Tire Sizing Chart example found in the Tire Safety
Information section of this manual for more information
relating to the Load Index and Speed Symbol of a tire.
502 STARTING AND OPERATING

If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the Tire Pressure Monitoring Telltale
Light will no longer flash, theSERVICE 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 driving 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 EVIC will also display a
SERVICE TPM SYSTEM
message for a minimum of five seconds when a system
fault is detected possibly related to the trigger compo-
nent 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 but they may not be located in the
correct vehicle position. However, the system still needs
to be serviced as long as the SERVICE 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, the Tire Pressure
Monitoring Telltale Light will remain ON, a chime will
sound, and the EVIC will still display a “flashing” pressure

value in the graphic display. After driving the vehicle for up
to 20 minutes above 15 mph (24 km/h), the Tire Pressure
Monitoring Telltale Light will flash on and off for 75 sec-
onds and then remain on solid. In addition, the EVIC will
display a “SERVICE TPM SYSTEMmessage for three
seconds and then display dashes (- -) in place of the
pressure value. For each subsequent ignition switch cycle, a
chime will sound, the Tire Pressure Monitoring Telltale
Light will flash on and off for 75 seconds and then remain
on solid, and the EVIC will display a SERVICE TPM
SYSTEM message for three seconds and then display
dashes (- -) in place of the pressure value. 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
automatically.
In addition, the Tire Pressure Monitoring Telltale Light will
turn OFF and 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.

WARNING!(Continued)
•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 purposes. The vehicle
should be jacked on a firm level surface only.
Avoid ice or slippery areas.
Run Flat Tires
This vehicle is equipped with a compact spare along with
run flat tires. Although the tires are designed with a “run
flat” feature that allows the vehicle to be driven approxi-
mately 50 miles (80 km) at 55 mph (88 km/h). immediate
service should be obtained. NOTE:
The compact spare tire is to be used fro rear
wheel(s) only. For a flat front tire, move the rear tire to the
front and use the compact spare on the rear.
WARNING!
• Do not exceed 50 mph (80 km/h) if the “Tire
Pressure Monitoring Telltale Light” is illuminated.
Vehicle handling and braking may be reduced. You
could have a collision and be severely or fatally
injured.
• Do not tow a trailer when using the compact spare
tire.
538 WHAT TO DO IN EMERGENCIES

Jack Location
The scissor-type jack and tire changing tools are located
in rear cargo area, below the load floor.
Spare Tire Stowage
The 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 orslippery 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.

WARNING!(Continued)
•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. If
you need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.”
• 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 extremely
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.
