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. Also, the
TPMS sensor matching process should 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. Press the Remote Keyless Entry (RKE) transmitter's lock and unlock buttons at the same
time for approximately five seconds. The horn
sounds twice to signal the receiver is in relearn
mode and TIRE LEARNING ACTIVE message
displays on the DIC screen. 4. Start with the driver side front tire.
5. 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.
6. Proceed to the passenger side front tire, and repeat the procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat the procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat the procedure in Step 5. 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sensor matching process is no longer active.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.
9. Turn the ignition to LOCK/OFF.
10. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading
Information label.

Tire Sealant and Compressor Kit
{WARNING:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains
Carbon Monoxide (CO) which cannot be seen
or smelled. It can cause unconsciousness and
even death. Never run the engine in an enclosed
area that has no fresh air ventilation. For more
information, seeEngine Exhaust on page 3‑30.
{WARNING:
Overinflating a tire could cause the tire to
rupture and you or others could be injured. Be
sure to read and follow the tire sealant and
compressor kit instructions and inflate the tire to
its recommended pressure. Do not exceed the
recommended pressure.
{WARNING:
Storing the tire sealant and compressor kit or
other equipment in the passenger compartment of
the vehicle could cause injury. In a sudden stop or
collision, loose equipment could strike someone.
Store the tire sealant and compressor kit in its
original location.
If this vehicle has a tire sealant and compressor kit,
there may not be a spare tire, tire changing equipment,
and on some vehicles there may not be a place to store
a tire.
The tire sealant and compressor can be used to
temporarily seal punctures up to 6 mm (¼ in) in the
tread area of the tire. It can also be used to inflate an
under inflated tire.
If the tire has been separated from the wheel, has
damaged sidewalls, or has a large puncture, the tire
is too severely damaged for the tire sealant and
compressor kit to be effective. See Roadside
Assistance Program on page 8‑7.

Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place, well off the road,
if possible. Turn on the hazard warning flashers. See
Hazard Warning Flashers on page 4‑3.
{WARNING:
Changing a tire can be dangerous. The vehicle
can slip off the jack and roll over or fall on you or
other people. You and they could be badly injured
or even killed. Find a level place to change your
tire. To help prevent the vehicle from moving:1. Set the parking brake firmly.
2. Put the shift lever in P (Park).
3. Turn off the engine and do not restart while the vehicle is raised.
4. Do not allow passengers to remain in the vehicle.
To be even more certain the vehicle will not move,
you should put blocks at the front and rear of the
tire farthest away from the one being changed.
That would be the tire, on the other side, at the
opposite end of the vehicle. When the vehicle has a flat tire (B), use the following
example as a guide to assist you in the placement of
wheel blocks (A).
A. Wheel Block
B. Flat Tire
The following information explains how to use the jack
and change a tire.

Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall upon and
attack painted surfaces on the vehicle. This damage
can take two forms: blotchy, ring-shaped discolorations,
and small, irregular dark spots etched into the paint
surface.
Although no defect in the paint job causes this, we will
repair, at no charge to the owner, the surfaces of new
vehicles damaged by this fallout condition within
12 months or 20 000 km (12,000 mi) of purchase,
whichever occurs first.
Vehicle Identification
Vehicle Identification Number (VIN)
This legal identifier is in the front corner of the
instrument panel, on the driver side. It can be seen
through the windshield from outside. The VIN also
appears on the Vehicle Certification and Service Parts
labels and certificates of title and registration.
Engine Identification
The eighth character in the VIN is the engine code. This
code identifies the vehicle's engine, specifications, and
replacement parts. See“Engine Specifications”under
Capacities and Specifications
on page 6‑116for the
vehicle's engine code.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of fires
caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating.
You will find a fuse puller clipped in both of the fuse
blocks. Snap the wide end of the fuse puller at the side
indentations and pull the fuse out.The MaxiFuses are located in two fuse blocks, one
located in the engine compartment on the passenger's
side and the other under the rear seat on the driver's
side. If a MaxiFuse should blow, have your vehicle
serviced by your dealer immediately.
Underhood Fuse Block
The underhood fuse block is located on the passenger
side of the engine compartment. Remove the fuse cover
and secondary service cover to access the fuse block.
Notice:
Spilling liquid on any electrical component
on the vehicle may damage it. Always keep the
covers on any electrical component.
