TIRE PRESSURE MONITOR SYSTEM
The Tire Pressure Monitor (TPM) system uses wireless
technology to monitor tire pressure levels. Sensors
mounted to each wheel as part of the valve stem transmit
tire pressure readings to a receiver located inside the
vehicle.
NOTE:The TPM system can inform you about a low
tire pressure condition, but it does not replace normal tire
maintenance. The TPM system is not intended to provide
you with notification of rapid tire pressure loss.
CAUTION!
The TPM system is designed to monitor your tire
pressure and will not function as a tire pressure
gauge. After adjusting the air pressure in a tire, there
will be a delay before the system updates the dis-
play.
The TPM system will cause the indicator lamp in the
instrument cluster to illuminate whenever the pressure in
one tire falls 25% below the recommended pressure
shown on the vehicle’s tire label.
NOTE:The pressure in your tires changes with tem-
perature. A significant decrease in temperature could
reduce cold inflation pressure below the TPM setpoint.
For example, tires inflated to the proper cold inflation
pressure on a warm day or in a warm garage could
illuminate the TPM indicator lamp on the following day
if the temperature is very cold.ALWAYScheck the
pressure in your tires if the TPM lamp is illuminated.

CAUTION!
The TPM system has been optimized for the original
equipment tires and wheels. TPM system pressures
have been established for the tire size equipped on
your vehicle. Undesirable operation or sensor dam-
age may result when using replacement equipment
that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Do
not use aftermarket tire sealant or balance beads, as
damage to the sensors may result.
NOTE:The standard TIREFIT system (refer to What To
Do In Emergencies for more information) is specifically
designed to operate in conjunction with the TPM system,
and will not damage the sensors.
If your tire pressure is low, you should correct your tire
inflation pressure as soon as possible and inspect all of
your tires. Low tire pressure will cause the tire pressure
light to illuminate and the alert will sound. They will
remain on for the rest of the driving cycle, or until the tire
pressure is corrected.
In addition to monitoring tire pressures, the TPM system
also monitors faults within the system. If the TPM light
and alarm continue after the tire pressure has been
corrected, see your authorized dealer.
This device complies with part 15 of FCC rules and with
RSS-210 of Industry Canada. Operation is subject to the
following conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference that may be
received, including interference that may cause undes-
ired operation.

3. Coolant Indicator Light
This indicator illuminates when the engine
coolant has dropped below the requiredlevel in the reservoir or the coolant temperature is too
high (see the Temperature gauge section).
To check the coolant level, the vehicle must be parked on
level ground and the engine stopped.
Check coolant level only when the coolant is cold.
WARNING!
You or others can be badly burned by hot coolant or
steam from your radiator. If you see or hear steam
coming from under the hood, don’t open the hood
until the radiator has had time to cool. Never try to
open a cooling system pressure cap when the radia-
tor or coolant bottle is hot.
4. Engine Coolant Temperature Gauge
This gauge shows engine coolant temperature. Any read-
ing between the Hot and Cold gauge marks show that the
engine cooling system is operating properly. The gauge
pointer may show a higher temperature when driving in
hot weather, up mountain grades, or in heavy stop-and-
go-traffic.

128 STARTING AND OPERATING

In the case of an emergency brake maneuver, keep
continuous full pressure on the brake pedal. In this
manner only can the ABS be most effective.
On slippery road surfaces, the ABS will respond even
with light brake pedal pressure because of the in-
creased likelihood of locking wheels. The pulsating
brake pedal can be an indication of hazardous road
conditions and functions as a reminder to take extra
care while driving.
WARNING!
Significant over- or under-inflation of tires, or mix-
ing sizes of front or rear tires or wheels on the
vehicle can reduce braking effectiveness. Maintain
proper tire pressure and always use the tires and
wheels specified in this manual for your vehicle.
The anti-lock brake system conducts a low-speed self-test
at about 12 mph (20 km/h). If you have your foot lightly
on the brake while this test is occurring, you may feel
slight pedal movement. The movement can be moreapparent on ice and snow. The anti-lock brake system
pump motor makes a low humming noise during opera-
tion, which is normal.
WARNING!
Pumping of the brake pedal will diminish the effec-
tiveness of the anti-lock brakes and may lead to an
accident. Pumping makes the stopping distance
longer. Just press firmly on your brake pedal when
you need to slow down or stop.
NOTE:During severe braking conditions, a pulsing
sensation may occur and a clicking noise will be heard.
This is normal, indicating that the anti-lock brake system
is functioning.
The ABS malfunction indicator light in the instrument
cluster comes on with the key in the ignition switch
turned to the ON/RUN position, and should go out with
the engine running. If the ABS light does not illuminate

TIRES
Please take the time to read the tire warranty booklet in
your Owner’s Manual package. It contains valuable
information on tire maintenance.
Specific recommendations on guidelines for long-term
tire storage should be requested of the tire manufacturer.
Please refer to the tire warranty booklet for contact
information.
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire pressure:
1. Safety
WARNING!
Improperly inflated tires are dangerous and can
cause accidents.
•Under inflation increases tire flexing and can
result in tire failure.
•Over inflation reduces a tire’s ability to cushion
shock. Objects on the road and chuck holes can cause
damage that results in tire failure.
•Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.
•Over inflated or under inflated tires can affect
vehicle handling and can fail suddenly, resulting in
loss of vehicle control.
•Unequal tire pressures from one side of the vehicle
to the other can cause the vehicle to drift to the right
or left.
Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
148 STARTING AND OPERATING

2. Economy
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Underinflation also increases tire
rolling resistance and results in higher fuel consumption.
3. Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Overinflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure for passenger cars
is listed on the face of the driver’s door latch pillar.The pressure should be checked and adjusted as well as
inspecting for signs of tire wear or visible damage at least
once a month. Use a good quality pocket-type gauge to
check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are underinflated.
STARTING AND OPERATING 149

CAUTION!
After inspecting or adjusting the tire pressure al-
ways reinstall the valve stem cap—if equipped. This
will prevent moisture and dirt from entering the
valve stem, which could damage the valve stem.
Inflation pressures specified on the placard are always
“cold tire inflation pressure.”Cold tire inflation pressure
is defined as the tire pressure after the vehicle has not
been driven for at least 3 hours, or driven less than 1 mile
(1.6 km) after a 3 hour period. The cold tire inflation
pressure must not exceed the maximum inflation pres-
sure molded into the tire side wall.
Check tire pressures more often if subject to a wide range
of outdoor temperatures, as tire pressures vary with
temperature changes.
Tire pressures change by approximately 1 psi (7 kPa) per
12°F(7°C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage especially in
the winter.Example: If garage temperature = 68°F (20°C) and the
outside temperature = 32°F(0°C) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12°F(7°C) for this
outside temperature condition.
Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT reduce this normal pressure
build up or your tire pressure will be too low.
Tire Pressures for High Speed Operation
The manufacturer advocates driving at safe speeds
within posted speed limits. Where speed limits or condi-
tions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle
loading may be required for high speed vehicle opera-
tion. Refer elsewhere in this section for recommended
safe operating speeds, loading and cold tire inflation
pressures.
150 STARTING AND OPERATING

transmit tire pressure readings to a computer which
monitors for low pressure. If low pressure is measured,
the TPM Indicator Light will illuminate.
The TPM system informs you of a low tire pressure
condition. If this occurs, correct your tire inflation pres-
sure as soon as possible, and inspect all of your tires. Be
sure to use a high quality gauge when adjusting pressure.
The TPM system is designed to periodically monitor your
tire pressure but cannot be expected to function as a tire
pressure gauge. There can be a delay between the instant
you adjust the air pressure in a tire and when the system
updates the display. The TPM system is not intended to
provide you with notification of rapid air loss.
The TPM system will cause the indicator lamp in the
instrument cluster to illuminate whenever the pressure in
one tire falls 25% below the recommended pressure
shown on the tire label.
NOTE:A TPM system does not replace normal tire
maintenance.
CAUTION!
The TPM system has been optimized for the original
equipment tires and wheels. TPM system pressures
have been established for the tire size equipped on
your vehicle. Undesirable operation or sensor dam-
age may result when using replacement equipment
that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Do
not use aftermarket tire sealant or balance beads as
damage to the sensors may result. The standard
TIREFIT system (see Tirefit Tire Repair and Jacking
Instructions in the What To Do In Emergencies
section) is specifically designed to operate in con-
junction with the TPM system, and will not damage
the sensors.
NOTE:The pressure in your tires changes with tem-
perature. A significant decrease in temperature could
reduce cold inflation pressure below the TPM setpoint.
For example, tires inflated to the proper cold inflation
pressure on a warm day or in a warm garage could
illuminate the TPM indicator lamp on the following day
152 STARTING AND OPERATING

Tread Wear Indicators
Tread wear indicators are in the original equipment tires
to help you in determining when your tires should be
replaced.
These indicators are molded into the bottom of the tread
grooves and will appear as bands when the tread depth
becomes 1/16 inch (2 mm). When the indicators appear
in two or more adjacent grooves, the tire should be
replaced.
Many states have laws requiring tire replacement at this
point.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed (see the paragraph on tread
wear indicators). Refer to the Tire and Loading Informa-
tion placard for the size designation of your tire. The
service description and load identification will be found
on the original equipment tire. Failure to use equivalent
replacement tires may adversely affect the safety, han-
dling, and ride of your vehicle. We recommend that you
contact your original equipment or an authorized tire
dealer with any questions you may have on tire specifi-
cations or capability.
