.Replacement tires or wheels do
not match the original equipment
tires or wheels. Tires and wheels
other than those recommended
could prevent the TPMS from
functioning properly. SeeBuying
New Tires on page 10‑64.
.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
properly it cannot detect or signal a
low tire condition. See your dealer
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
identification code. The identification
code needs to be matched to a
new tire/wheel position after rotating
the vehicle’ s tires or replacing
one or more of the TPMS sensors.
The TPMS sensor matching process
should also be performed after
replacing a spare tire with a road
tire containing the TPMS sensor.
The malfunction light and the DIC
message should go off at the next
ignition cycle. The sensors are
matched to the tire/wheel positions,
using a TPMS relearn tool, in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear.
See your dealer for service or to
purchase a relearn tool. There are two minutes to match
the first tire/wheel position, and
five minutes overall to match all
four tire/wheel positions. If it takes
longer, the matching process stops
and must be restarted.
The TPMS sensor matching
process is:
1. Set the parking brake.
2. Turn the ignition to ON/RUN with
the engine off.
3. Use the MENU button to select the Vehicle Information Menu
in the Driver Information
Center (DIC).
4. Use the thumbwheel to scroll to the Tire Pressure Menu Item
screen.

5. Press the SET/CLR button tobegin the sensor matching
process.
A message asking if the process
should begin should appear.
6. Press the SET/CLR button again to confirm the selection.
The horn sounds twice to
signal the receiver is in relearn
mode and the TIRE LEARNING
ACTIVE message displays on
the DIC screen.
7. Start with the driver side front tire. 8. Place the relearn tool against
the tire sidewall, near the valve
stem. Then press the button
to activate the TPMS sensor.
A horn chirp confirms that the
sensor identification code has
been matched to this tire and
wheel position.
9. Proceed to the passenger side front tire, and repeat the
procedure in Step 8.
10. Proceed to the passenger side rear tire, and repeat the
procedure in Step 8. 11. Proceed to the driver side rear
tire, and repeat the procedure
in Step 8. The horn sounds
two times to indicate the
sensor identification code has
been matched to the driver
side rear tire, and the TPMS
sensor matching process is
no longer active. The TIRE
LEARNING ACTIVE message
on the DIC display screen
goes off.
12. Turn the ignition to LOCK/OFF.
13. Set all four tires to the recommended air pressure
level as indicated on the Tire
and Loading Information label.

3. Set the parking brake firmly andput the shift lever in P (Park).
See Shifting Into Park on
page 9‑25.
Notice: If the radio or other
accessories are left on during
the jump starting procedure, they
could be damaged. The repairs
would not be covered by the
warranty. Always turn off the
radio and other accessories
when jump starting the vehicle.
4. Turn the ignition to LOCK/OFF
and switch off all lights and
accessories in both vehicles,
except the hazard warning
flashers if needed.
{WARNING
An electric fan can start up even
when the engine is not running
and can injure you. Keep hands,
clothing and tools away from any
underhood electric fan.
{WARNING
Using a match near a battery can
cause battery gas to explode.
People have been hurt doing
this, and some have been
blinded. Use a flashlight if you
need more light.
Be sure the battery has enough
water. You do not need to add
water to the battery installed in
your new vehicle. But if a battery
has filler caps, be sure the right
amount of fluid is there. If it is low,
add water to take care of that
first. If you don't, explosive gas
could be present.
Battery fluid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
your eyes or on your skin, flush
the place with water and get
medical help immediately.
{WARNING
Fans or other moving engine
parts can injure you badly. Keep
your hands away from moving
parts once the engine is running.
5. Connect one end of the redpositive (+) cable to the jump
start positive (+) post (A). Use a
remote positive (+) terminal if the
vehicle has one.

with all four wheels on the ground:
1. Position the vehicle being towedbehind the tow vehicle and shift
the transmission to P (Park).
2. Turn the engine off and firmly set the parking brake. 3. Following the manufacturer's
instructions, securely attach the
vehicle being towed to the tow
vehicle.

firmly attached to the towing
vehicle.
When towing the vehicle for
extended periods of time, start
the vehicle as often as possible to
prevent battery drain. This should
be done when the tow vehicle is
parked.
