76 GETTING TO KNOW YOUR INSTRUMENT PANEL
When the engine is running, the MIL may flash to
alert serious conditions that could lead to
immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced
by an authorized dealer as soon as possible if this
occurs.Service AWD Warning Light — If Equipped
This warning light will turn on to indicate
the All Wheel Drive (AWD) system is not
fu
nctioning properly and that service is
required. Contact an authorized dealer.
Service Forward Collision Warning (FCW)
Light — If Equipped
This warning light will illuminate to
indicate a fault in the Forward Collision
W a
rning System. Contact an authorized
dealer for service
Ú page 146.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a
message is displayed to indicate that the
ti
re pressure is lower than the
recommended value and/or that slow
pressure loss is occurring. In these cases, optimal
tire duration and fuel consumption may not be
guaranteed.
Should one or more tires be in the condition
m e

ntioned above, the display will show the
indications corresponding to each tire. Each tire, including the spare (if provided), should
b
e

checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
inflation pressure label. If your vehicle has tires of
a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure
for those tires.
As an added safety feature, your vehicle has been
e q

uipped with a TPMS that illuminates a low tire
pressure warning light when one or more of your
tires is significantly underinflated. Accordingly,
when the low tire pressure warning light
illuminates, you should stop and check your tires
as soon as possible, and inflate them to the proper
pressure. Driving on a significantly underinflated
tire causes the tire to overheat and can lead to tire
failure. Underinflation also reduces fuel efficiency
and tire tread life, and may affect the vehicle’s
handling and stopping ability.
WARNING!
A malfunctioning catalytic converter, as refer -
enced above, can reach higher temperatures
t h
an in normal operating conditions. This can
cause a fire if you drive slowly or park over flam -
mable substances such as dry plants, wood,
c a

rdboard, etc. This could result in death or seri -
ous injury to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the
vehicle control system. It also could affect fuel
economy and driveability. If the MIL is flashing,
severe catalytic converter damage and power
loss will soon occur. Immediate service is
required.
CAUTION!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop the
vehicle, avoiding sharp braking and steering. If a
tire puncture occurs, repair immediately using
the dedicated tire repair kit and contact an
authorized dealer as soon as possible.

independently.

SAFETY 149
NOTE:
The TPMS is not intended to replace normal tire
care and maintenance or to provide warning of
a tire failure or condition.
The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire
failure. Underinflation also reduces fuel effi
-
ciency and tire tread life, and may affect the
v e

hicle’s handling and stopping ability.
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility
to maintain correct tire pressure using an accu -
rate tire pressure gauge, even if underinflation
h a

s not reached the level to trigger illumination
of the TPMS Warning Light.
Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the actual
tire pressure in the tire.
The Tire Pressure Monitoring System (TPMS) uses
w i

reless technology with wheel rim mounted
electronic sensors to monitor tire pressure levels.
Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to the
receiver module
Ú page 254.
NOTE:
It is particularly important for you to check the tire
p r
essure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
Receiver module.
Four Tire Pressure Monitoring System sensors.
Various Tire Pressure Monitoring System
messages, which display in the instrument
cluster.
Tire Pressure Monitoring System Warning Light.
Tire Pressure Monitoring System Low
Pressure Warnings
The Tire Pressure Monitoring System
(TPMS) Warning Light will illuminate in
t h
e instrument cluster and a chime will
sound when tire pressure is low in one or
more of the four active road tires. In addition, the
instrument cluster will display an “Inflate to XX”
message and a graphic showing the pressure
values of each tire with the low tire pressure values
shown in a different color.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may
result when using replacement equipment
that is not of the same size, type, and/or style.
The TPMS sensor is not designed for use on
aftermarket wheels and may contribute to a
poor overall system performance or sensor
damage. Customers are encouraged to use
Original Equipment Manufacturer (OEM)
wheels to ensure proper TPMS feature opera -
tion.
Using aftermarket tire sealants may cause the
Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended
that you take your vehicle to an authorized
dealer to have your sensor function checked.
After inspecting or adjusting the tire pressure
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the TPMS
sensor.

178 SAFETY
(Continued)
lug nuts/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
EXHAUST GAS
The best protection against carbon monoxide entry
into the vehicle body is a properly maintained
engine exhaust system.
Whenever a change is noticed in the sound of the
ex

haust system, when exhaust fumes can be
detected inside the vehicle, or when the underside
or rear of the vehicle is damaged, have an
authorized dealer inspect the complete exhaust
system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts.
Open seams or loose connections could permit
exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust
system each time the vehicle is raised for
lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you. To
avoid breathing (CO), follow these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/lift -
gate/rear doors open, make sure that all
w i
ndows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.
WARNING!
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to prevent
carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in a
closed area, such as a garage, and never sit in
a parked vehicle with the engine running for
an extended period. If the vehicle is stopped in
an open area with the engine running for more
than a short period, adjust the ventilation
system to force fresh, outside air into the
vehicle.
Guard against carbon monoxide with proper
maintenance. Have the exhaust system
inspected every time the vehicle is raised.
Have any abnormal conditions repaired
promptly. Until repaired, drive with all side
windows fully open.

TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the
safe and satisfactory operation of your vehicle.
Four primary areas are affected by improper tire
pressure:
Safety
Fuel Economy
Tread Wear
Ride Comfort and Vehicle Stability
Safety Both underinflation and overinflation affect the
st
ability of the vehicle and can produce a feeling of
sluggish response or over responsiveness in the
steering.
NOTE:
Unequal tire pressures from side to side may
cause erratic and unpredictable steering
response.
Unequal tire pressure from side to side may
cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling
r e

sistance resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause
a b

normal wear patterns and reduced tread life,
resulting in the need for earlier tire replacement. Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable
r
i

de. Overinflation produces a jarring and
uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on
the driver's side B-pillar or rear edge of the driver's
side door.
At least once a month:
Check and adjust tire pressure with a good
quality pocket-type pressure gauge. Do not
make a visual judgement when determining
proper inflation. Tires may look properly inflated
even when they are underinflated.
Inspect tires for signs of tire wear or visible
damage.
Inflation pressures specified on the placard are
a l

ways “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
WARNING!
Improperly inflated tires are dangerous and
can cause collisions.
Underinflation increases tire flexing and can
result in overheating and tire failure.
Overinflation reduces a tire's ability to cushion
shock. Objects on the road and chuckholes
can cause damage that result in tire failure.
Overinflated or underinflated tires can affect
vehicle handling and can fail suddenly,
resulting in loss of vehicle control.
Unequal tire pressures can cause steering
problems. You could lose control of your
vehicle.
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
recommended cold tire inflation pressure.
WARNING!
CAUTION!
After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the valve stem.
