Information on “T” type tires
“T” type tires have some additional
information beyond those of “P”
type tires; these differences are
described below:
T145/80D16 is an example of a tire
size.
Note:The temporary tire size for
your vehicle may be different from
this example.
1.T:Indicates a type of tire,
designated by the Tire and Rim
Association (T&RA), that is
intended for temporary service on
cars, SUVs, minivans and light
trucks.
2.145:Indicates the nominal width
of the tire in millimeters from
sidewall edge to sidewall edge. In general, the larger the number, the
wider the tire.
3.80:Indicates the aspect ratio which gives the tire’s ratio of height to
width. Numbers of 70 or lower indicate a short sidewall.
4.D:Indicates a “diagonal” type tire.
R:Indicates a “radial” type tire.
5.16:Indicates the wheel or rim diameter in inches. If you change your
wheel size, you will have to purchase new tires to match the new wheel
diameter.
Location of the tire label
You will find a Tire Label containing tire inflation pressure by tire size
and other important information located on the B-Pillar or the edge of
the driver’s door. Refer to the payload description and graphic in the
Vehicle loading — with and without a trailersection.

TIRE PRESSURE MONITORING SYSTEM (TPMS)
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. (If your vehicle has tires
of a different size than the size indicated on the vehicle placard or tire
inflation pressure label, you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that illuminates a low tire pressure
telltale when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible, and inflate them to the
proper pressure. Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator
to indicate when the system is not operating properly. The TPMS
malfunction indicator is combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously illuminated.
This sequence will continue upon subsequent vehicle start-ups as long as
the malfunction exists.
When the malfunction indicator is illuminated, the system may not be
able to detect or signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the installation of
replacement or alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS malfunction
telltale after replacing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and wheels allow the
TPMS to continue to function properly.

When you believe your system is not operating properly
The main function of the Tire Pressure Monitoring System is to warn you
when your tires need air. It can also warn you in the event the system is
no longer capable of functioning as intended. Please refer to the

When inflating your tires
When putting air into your tires (such as at a gas station or in your
garage), the Tire Pressure Monitoring System may not respond
immediately to the air added to your tires.
It may take up to two minutes of driving over 20 mph (32 km/h) for the
light to turn OFF after you have filled your tires to the recommended
inflation pressure.
How temperature affects your tire pressure
The Tire Pressure Monitoring System (TPMS) monitors tire pressure in
each pneumatic tire. While driving in a normal manner, a typical
passenger tire inflation pressure may increase approximately 2 to 4 psi
(14 to 28 kPa) from a cold start situation. If the vehicle is stationary
over night with the outside temperature significantly lower than the
daytime temperature, the tire pressure may decrease approximately 3 psi
(20.7 kPa) for a drop of 30° F (16.6°C) in ambient temperature. This
lower pressure value may be detected by the TPMS as being significantly
lower than the recommended inflation pressure and activate the TPMS
warning for low tire pressure. If the low tire pressure warning light is
ON, visually check each tire to verify that no tire is flat. (If one or more
tires are flat, repair as necessary.) Check air pressure in the road tires. If
any tire is under-inflated, carefully drive the vehicle to the nearest
location where air can be added to the tires. Inflate all the tires to the
recommended inflation pressure.

•Do notdrive farther than 120 miles (193 km). Drive only to the
closest authorized dealer or tire dealer.
•Drive carefully and avoid abrupt steering maneuvers.
•Periodically monitor tire inflation pressure in the affected tire; if the
tire is losing pressure, have the vehicle towed.
•Read the information in theTips for use of the temporary mobility
kitsection to ensure safe operation of the temporary mobility kit and
your vehicle.
Tips for use of the temporary mobility kit
Read the following list of tips to ensure safe operation of the temporary
mobility kit:
•Before operating the temporary mobility kit, make sure your vehicle is
safely off the road and away from moving traffic.
•Always set the parking brake to ensure the vehicle doesn’t move
unexpectedly.
•Do not remove any foreign objects, such as nails or screws, from the
tire.
•When using the temporary mobility kit, leave the engine running
(only if the vehicle is outdoors or in a well-ventilated area)so
the compressor doesn’t drain the vehicle’s battery.
•Do not allow the compressor to operate continuously for more than
10 minutes; this will help prevent the compressor from overheating.
•Never leave the temporary mobility kit unattended when it is
operating.
•Keep the temporary mobility kit away from children.
•Only use the temporary mobility kit when the ambient temperature is
above –20°F (-29°C).
•Only use the temporary mobility kit for sealing/inflating the tires on
your vehicle. Do not use the kit for inflating tires on motorcycles,
bicycles or any other type of tire.
•Only use the sealing compound before the expiration date. The
expiration date is labeled on the unit.
•Do not store the temporary mobility kit inside the passenger
compartment of the vehicle as it may cause injury during a sudden
stop or collision. Store the kit in its proper location.

What to do when a tire is punctured
A tire puncture within the tire’s tread area can be repaired in two stages
with the temporary mobility kit:
•In the first stage, the tire will be reinflated with a sealing compound
and air. After the tire has been reinflated, you will need to drive the
vehicle a short distance (approximately two miles) to activate the
sealing compound inside the tire.
•In the second stage, you will need to check the tire pressure and, if
necessary, adjust tire inflation to its proper pressure.
First stage: Reinflating the tire with sealing compound and air
1. Remove the hose (1) and the cable with the electrical plug (2) from
the kit’s storage compartment (3).
2. Remove the valve cap from the punctured tire, then screw the hose
firmly onto the tire’s air valve.
3. Insert the electrical plug into the vehicle’s dash mounted power point.

Note:When the sealing compound
is first added into the tire, the air
pressure gauge reading (7) on the
compressor unit may increase up to
90 psi; this is normal and should be
no reason for concern. The pressure
will drop after about 30 seconds of
operation.
Do not stand directly over the temporary mobility kit while
inflating the tire. If you notice any unusual bulges or
deformations in the tire’s sidewall during inflation, stop the air
compressor and deflate the tire using the pressure release valve. The
pressure release valve is located on the hose.
8. Inflate the tire until the tire reaches the recommended placard
pressure, then turn the air compressor off by pressing the “O” side of the
orange button.
Note:If the damaged tire does not reach the recommended placard
pressure within nine minutes, the tire is too severely damaged and the
car must not be driven. Call for roadside assistance.
9. Once the tire pressure reaches the recommended placard pressure,
quickly unscrew the hose from the tire’s air valve and reinstall the valve
cap. Unplug the electrical plug from the power point. Turn the sealing
compound container back to its original position and close the safety
latch. Stow the temporary mobility kit back in the original location. You
will need it again to check the tire’s air pressure in the second stage of
this operation.
10.Immediately, and cautiously, drive the vehicle a short distance
(approximately two miles [3.2 km]) to activate the sealing compound
within the damaged tire. Do not exceed 50 mph (80 km/h).
Note:If you experience any unusual vibration, ride disturbance or noise
while driving, reduce your speed until you can safely pull off to the side
of the road to call for roadside assistance.Do not proceed to the
second stage of this operation.
