Tire Designations
Tire Size
The following illustration shows
an example of a typical
passenger vehicle tire size.
(A) Passenger (P‐Metric) Tire:
The United States version of a
metric tire sizing system. The
letter P as the first character in
the tire size means a passenger
vehicle tire engineered to
standards set by the U.S. Tire
and Rim Association.(B) Tire Width
:The three‐digit
number indicates the tire section
width in millimeters from
sidewall to sidewall.
(C) Aspect Ratio
:A two‐digit
number that indicates the tire
height‐to‐width measurements.
For example, if the tire size
aspect ratio is 60, as shown in
item C of the illustration, it would
mean that the tire's sidewall is
60 percent as high as it is wide.
(D) Construction Code
:A
letter code is used to indicate
the type of ply construction in
the tire. The letter R means
radial ply construction; the
letter D means diagonal or
bias ply construction; and the
letter B means belted‐bias ply
construction. (E) Rim Diameter
:Diameter of
the wheel in inches.
(F) Service Description
:These
characters represent the load
index and speed rating of the
tire. The load index represents
the load carry capacity a tire is
certified to carry. The speed
rating is the maximum speed a
tire is certified to carry a load.

Vehicle Care 9-57
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. Any time you
rotate your vehicle's tires or replace
one or more of the TPMS sensors,
the identification 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. If increasing the
tire's air pressure, do not exceed
the maximum inflation pressure
indicated on the tire's sidewall.To decrease air-pressure out of a
tire you can use the pointed end of
the valve cap, a pencil-style air
pressure gauge, or a key.
You have two minutes to match
the first tire/wheel position, and
five minutes overall to match all four
tire/wheel positions. If it takes longer
than two minutes, to match the first
tire and wheel, or more than
five minutes to match all four tire
and wheel positions the matching
process stops and you need to
start over.
The TPMS sensor matching process
is outlined below:
1. Set the parking brake.
2. Turn the ignition switch 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. Remove the valve cap from the valve cap stem. Activate the
TPMS sensor by increasing or
decreasing the tire's air pressure
for five seconds, or until a
horn chirp sounds. The horn
chirp, which may take up to
30 seconds to sound, 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.

9-68 Vehicle Care
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the hazard
warning flashers. SeeHazard
Warning Flashers on page 5‑3.
{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 an automatic transmission shift lever in
P (Park), or shift a manual
transmission to 1 (First) or
R (Reverse).
(Continued)
WARNING (Continued)
3. Turn off the engine and donot restart while the vehicle
is raised.
4. Do not allow passengers to remain in the vehicle.
To be certain the vehicle will not
move, 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 repair or change a tire.

Vehicle Care 9-79
1. The vehicle used to jump startmust have 12-volt battery with a
negative ground.
Notice: If the other vehicle's
system is not a 12-volt system
with a negative ground, both
vehicles can be damaged. Only
use vehicles with 12-volt systems
with negative grounds to jump
start your vehicle.
2. The vehicles should be close enough for the jumper cables to
reach, but the vehicles should
not be touching. Touching could
cause grounding and possible
electrical system damage.
Put both vehicles in P (Park)
and set the parking brake firmly.
3. Unplug accessories plugged into the cigarette lighter or the
accessory power outlet. Turn off
the radio and all lamps that are
not needed. Turn off the ignition
on both vehicles. 4. Locate the positive (+) and
negative (−) terminals on both
vehicles. Some vehicles have
remote jump starting terminals.
{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. 5. The remote positive (+)
terminal (A) is located on the
underhood fuse block, on the
driver side. Lift the red cap to
uncover the terminal.
The remote negative (−)
terminal (B) is a stud behind the
metal tab stamped with GND (−)
near the driver side strut tower.
6. The jumper cables should be in good working condition with no
loose or missing insulation. The
vehicles could be damaged if
they are not.
7. Connect the red positive (+) cable to the positive (+) terminal
on the vehicle with the dead
battery. Use a remote
positive (+) terminal if the
vehicle has one.

9-80 Vehicle Care
8. Do not let the other end touchmetal. Connect it to the
positive (+) terminal of the
good battery. Use a remote
positive (+) terminal if the vehicle
has one.
9. Connect the black negative (−) cable to the negative (−) terminal
of the good battery. Use a
remote negative (−) terminal if
the vehicle has one.
Do not let the other end touch
anything until the next step. The
other end of the negative (−)
cable does not go to the dead
battery. It goes to a heavy,
unpainted metal engine part or
to a remote negative (−) terminal
on the vehicle with the dead
battery.
10. Connect the other end of the negative (−) cable away from
the dead battery, but not near
engine parts that move. 11. Start the vehicle with the good
battery and run the engine.
12. Press the unlock symbol on the remote keyless entry
transmitter to disarm the
security system, if equipped.
13. Try to start the vehicle that had the dead battery. If it will not
start after a few tries, it needs
service.
Notice: If the jumper cables are
connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by the vehicle warranty.
Always connect and remove the
jumper cables in the correct
order, making sure that the
cables do not touch each other or
other metal.

4. Turn all accessories off.
5. To prevent the battery fromdraining while the vehicle is
being towed, remove fuse 32,
the Discrete Logic Ignition
Switch fuse, from the instrument
panel fuse block and store it in a
safe location. See Instrument
Panel Fuse Block on page 9‑42.
Notice: If the vehicle is towed
without performing each of the
steps listed under “Dinghy
Towing,” the automatic
transmission could be damaged.
Be sure to follow all steps of the
dinghy towing procedure prior to
and after towing the vehicle.
Notice: If 105 km/h (65 mph) is
exceeded while towing the
vehicle, it could be damaged.
Never exceed 105 km/h (65 mph)
while towing the vehicle. Once the destination has been
reached:
1. Set the parking brake.
2. Shift the transmission to
P (Park).
3. Turn the ignition key to LOCK/OFF.
4. Install fuse 32, the Discrete Logic Ignition Switch fuse. See
Instrument Panel Fuse Block
on
page 9‑42.
5. Start the engine and let it idle for more than three minutes before
driving the vehicle.
Notice: Too much or too
little fluid can damage the
transmission. Be sure that the
transmission fluid is at the proper
level before towing with all four
wheels on the ground. Notice:
Do not tow a vehicle with
the front drive wheels on the
ground if one of the front tires is
a compact spare tire. Towing with
two different tire sizes on the
front of the vehicle can cause
severe damage to the
transmission.
Dolly Towing
(All-Wheel‐Drive Vehicles)
All-wheel‐drive vehicles should not
be towed with two wheels on the
ground. To properly tow these
vehicles, they should be placed on
a platform trailer with all four wheels
off of the ground or dinghy towed
from the front.
