Replacement tires or wheels do not match your
vehicle’s original equipment tires or wheels.
Tires and wheels other than those recommended
for your vehicle could prevent the TPMS from
functioning properly. SeeBuying New Tires on
page 5-66.
Operating electronic devices or being near
facilities using radio wave frequencies similar
to the TPMS could cause the TPMS sensors to
malfunction.
If the TPMS is not functioning it cannot detect or
signal a low tire condition. See your dealer/retailer for
service if the TPMS malfunction light and DIC message
comes on and stays on.
TPMS Sensor Matching Process
Each TPMS sensor has a unique identication code.
Any time you replace one or more of the TPMS sensors
or rotate the vehicle’s tires, the identication codes
need to be matched to the new tire/wheel location.
The sensors are matched, to the tire/wheel locations, in
the following order: driver side front tire, passenger
side front tire, passenger side rear tire, and driver side
rear tire using a TPMS diagnostic tool. See your
dealer/retailer for service.
The TPMS sensors can also be matched to each
tire/wheel position by increasing or decreasing the tire’s
air pressure. When increasing the tire’s pressure, do
not exceed the maximum ination pressure indicated on
the tire’s sidewall. To decrease the tire’s air-pressure
use the pointed end of the valve cap, a pencil-style
air pressure gage, or a key.
You have two minutes to match each tire and wheel
position. If it takes longer than two minutes to match any
tire and wheel position, the matching process stops
and you need to start over.

The TPMS matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the
engine off.
3. Press and hold the Remote Keyless Entry (RKE)
transmitter’s LOCK and UNLOCK buttons, at the
same time, for about ve seconds to start the TPMS
learn mode. The horn sounds twice indicating the
TPMS receiver is ready and in learn mode.
4. Start with the driver side front tire. The driver side
front turn signal also comes on to indicate that
corner’s sensor is ready to be learned.
5. Remove the valve cap from the tire’s valve stem.
Activate the TPMS sensor by increasing or
decreasing the tire’s air pressure for about
eight seconds. The horn chirp, can take up to
30 seconds to sound. It chirps one time and then
all the turn signals ash one time to conrm the
sensor identication code has been matched to
the tire/wheel position.
6. The passenger side front turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the passenger side front tire and
repeat the procedure in Step 5.7. The passenger side rear turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the passenger side rear tire and
repeat the procedure in Step 5.
8. The driver side rear turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the driver side rear tire, and repeat
the procedure in Step 5.
9. After hearing the single horn chirp for the driver
side rear tire, two additional horn chirps sound to
indicate the tire learning process is done.
Turn the ignition switch to LOCK/OFF.
If no tires are learned after entering the TPMS
learn mode, or if communication with the receiver
stops, or if the time limit has expired, turn the
ignition switch to LOCK/OFF and start over
beginning with Step 2.
10. Set all four tires to the recommended air pressure
level as indicated on the Tire and Loading
Information label.
11. Put the valve caps back on the valve stems.

Tire Sealant
Read and follow the safe handling instructions on the
sealant canister.
The sealant can temporarily seal a punctures up to
14inch (6 mm) in the tread area of the tire. The sealant
cannot seal sidewall damage, large punctures, or a
tire that has unseated from the wheel. SeeRoadside
Assistance Program on page 7-7if you need assistance.
The sealant can only be used to seal one tire.
After usage, the sealant canister and sealant lling
hose assembly must be replaced at a dealer/retailer.
See Removal and Installation of Sealant Canister later
in this section.
Check the tire sealant expiration date on the sealant
canister, if it has expired, see your dealer/retailer for
a replacement.
Using the Tire Sealant and Compressor
Kit to Temporarily Seal a Punctured Tire
Follow these directions closely for correct sealant usage.
1. Place the sealant and compressor kit on the ground
and unwrap the sealant lling hose from the
compressor.
2. Remove the air compressor accessory plug from
the unit. To do this, pull the top portion of the
wrapped cord out rst, then the bottom, and then
unsnap the plug. Do not insert the plug into an
accessory outlet yet.
3. Remove the valve stem or tire pressure monitoring
sensor cap from the at tire by turning it
counterclockwise.
If an object, such as a nail, has penetrated the tire,
do not remove it.

7. Push the On/Off switch to the I (on) position.
The sealant and compressor kit injects sealant and
air into the tire. Sealant could leak from the
puncture until the vehicle is driven and the puncture
has sealed.
8. The pressure gage will initially show a high pressure
while the compressor pushes the sealant into the
tire. Once the sealant is completely dispersed in
the tire, the pressure will quickly drop and start to
rise again as the tire inates.
9. Inate the tire to the recommended ination
pressure, found on the Tire and Loading Information
label located on the vehicle’s center pillar (B-pillar)
below the vehicle’s door latch, using the air
pressure gage on the top of the unit.
The pressure gage reads high while the compressor
is running. Turn the compressor off to get an
accurate pressure reading.
Notice:If the recommended pressure cannot be
reached after 15 minutes, the vehicle should not be
driven. The tire is too severely damaged and
cannot be inated or sealed with the tire sealant
and compressor kit. Remove the air compressor
accessory plug from the accessory power outlet and
unscrew the sealant lling hose from the tire
valve or tire pressure monitoring sensor valve.
SeeRoadside Assistance Program on page 7-7.10. Push the sealant and compressor kit switch to
the O (off) position.
11. The tire is not sealed and will continue to leak air
until the vehicle is driven and the sealant is
distributed in the tire.
Steps 12 through 20 must be done right after
Step 11.
12. Unplug the air compressor accessory plug from the
accessory power outlet in the vehicle.
13. Disconnect the sealant lling hose from the tire
valve stem, by turning it counterclockwise, and
replace the tire valve stem cap.
Be careful when handling the tire inator
components as they could be hot after usage.
14. Wrap the sealant lling hose around the air
compressor channel to stow it in its original location.
