Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn the
driver when a low tire pressure
condition exists. TPMS sensors are
mounted onto each tire and wheel
assembly, excluding the spare tire
and wheel assembly. The TPMS
sensors monitor the air pressure in
the vehicle’s tires and transmit the
tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning light on
the instrument panel cluster.The low tire pressure warning light
comes on at each ignition cycle
until the tires are inated to
the correct ination pressure.
The low tire pressure warning light
may come on in cool weather
when the vehicle is rst started, and
then turn off as you start to drive.
This may be an early indicator
that the air pressure in the tire(s)
are getting low and need to be
inated to the proper pressure.
A Tire and Loading Information
label, attached to your vehicle,
shows the size of your vehicle’s
original equipment tires and
the correct ination pressure for
your vehicle’s tires when they
are cold. SeeLoading the Vehicle
on page 4-28, for an example of the
Tire and Loading Information
label and its location on your
vehicle. Also seeInflation - Tire
Pressure on page 5-49.Your vehicle’s TPMS system can
warn you about a low tire pressure
condition but it does not replace
normal tire maintenance. SeeTire
Inspection and Rotation on
page 5-56andTires on page 5-43.
Notice:Liquid tire sealants could
damage the Tire Pressure Monitor
System (TPMS) sensors. Sensor
damage caused by using a tire
sealant is not covered by your
warranty. Do not use liquid tire
sealants.
TPMS Malfunction Light
The TPMS will not function properly
if one or more of the TPMS
sensors are missing or inoperable.
When the system detects a
malfunction, the low tire warning
light ashes for about one minute
and then stays on for the
remainder of the ignition cycle.

The TPMS malfunction light comes
on at each ignition cycle until the
problem is corrected. Some of
the conditions that can cause the
malfunction light to come on are:
One of the road tires has been
replaced with the spare tire. The
spare tire does not have a TPMS
sensor. The TPMS malfunction
light should go off once you
re-install the road tire containing
the TPMS sensor.
The TPMS sensor matching
process was started but not
completed or not completed
successfully after rotating the
vehicle’s tires. The TPMS
malfunction light should go
off once the TPMS sensor
matching process is performed
successfully. See “TPMS Sensor
Matching Process” later in this
section.
One or more TPMS sensors are
missing or damaged. The TPMS
malfunction light should go
off when the TPMS sensors
are installed and the sensor
matching process is performed
successfully. See your dealer/
retailer for service.
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 5-58.
Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
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 will need to
be matched to the new tire/wheel
position. The sensors are matched,
to the tire/wheel positions, 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
will 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 RKE
transmitter’s Lock and Unlock
buttons at the same time, for
about three seconds. The horn
will sound twice to indicate the
receiver is ready for the sensor
matching process to begin.4. Start with the driver side front
tire. The driver side turn signal
lamp comes on.
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 ve seconds, or until
a horn chirp sounds. The horn
chirp, which may take up to
30 seconds to sound, conrms
that the sensor identication code
has been matched to the
tire/wheel position.
6. Proceed to the passenger side
front tire. The passenger side
front turn signal lamp comes on.
Repeat the procedure in Step 5.
7. Proceed to the passenger side
rear tire. The passenger side
rear turn signal lamp comes on.
Repeat the procedure in Step 5.8. Proceed to the driver side rear
tire. The driver side rear turn
signal lamp comes on. Repeat the
procedure in Step 5. The horn
sounds two times to indicate the
sensor identication code has
been matched to the driver side
rear tire, and the TPMS sensor
matching process is no longer
active.
9. Turn the ignition switch to
LOCK/OFF.
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.
