When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replace-
ment or alternate tires and wheels allow the TPMS to
continue to function properly. (See page 355 for more
information.)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 opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use aftermarket tire sealants
or balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
23. Charging System Light
This light shows the status of the electrical charg-
ing system. The light should turn on when the
ignition switch is first turned ON and remain on briefly
as a bulb check. If the light stays on or turns on while

driving, turn off some of the vehicle’s non-essential
electrical devices (i.e. radio) or slightly increase engine
speed (if at idle). If the light remains on, it means that the
charging system is experiencing a problem. See your
local authorized dealer to obtain SERVICE IMMEDI-
ATELY.
24. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD. The OBD system monitors engine
and automatic transmission control systems. The
light will turn on when the key is in the ON position
before engine start. If the light does not come on when
turning the key from OFF to ON, have the condition
checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after
engine start. The vehicle should be serviced if the lightstays on through several of your typical driving cycles. In
most situations, the vehicle will drive normally and will
not require towing.
The Malfunction Indicator Light flashes to alert you to
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced as soon as possible if this occurs. (See
page 417 for more information.)
25. Oil Pressure Warning Light
This light shows low engine oil pressure. The light
should turn on momentarily when the engine is
started. If the light turns on while driving, stop the
vehicle, and shut off the engine as soon as possible. A
single chime will sound when this light turns on.
Do not operate the vehicle until the cause is corrected.
This light does not show how much oil is in the engine.
The engine oil level must be checked using the procedure
shown in section 7. (See page 421 for more information.)

WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph (8
km/h) when driving through standing water.
•Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
•Getting water inside your vehicle’s engine can
cause it to lockup and stall out and leave you
stranded.
•Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
PARKING BRAKE
The parking brake should always be applied when the
driver is not in the vehicle.
WARNING!
Never use “P” (Park) position on an automatic trans-
mission as a substitute for the parking brake. Always
apply parking brake fully when parked to guard
against vehicle movement and possible injury or
damage.
When parking on a flat surface, place the gear selector in
the “P” (Park) position first, and then apply the parking
brake.
When parking on a hill, it is important to apply the
parking brake before placing the gear selector in P (Park),

WARNING!
•Never leave children alone in a vehicle. Leaving
children in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Don’t leave the keys in
the ignition. A child could operate power win-
dows, other controls, or move the vehicle.
•Be sure the parking brake is fully disengaged
before driving: failure to do so can lead to brake
failure, and an accident.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic
brake systems. If either of the two hydraulic
systems loses normal capability, the remaining
system will still function. There will be some
loss of overall braking effectiveness. This may be evident
by increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the Brake Warning Light.
In the event power assist is lost for any reason (for
example, repeated brake applications with the engine off)
the brakes will still function. The effort required to brake
the vehicle will be much greater than that required with
the power system operating.

WARNING!
•The Anti-Lock Brake System contains sophisticated electronic
equipment that may be susceptible to interference caused by
improperly installed or high output radio transmitting equip-
ment. This interference can cause possible loss of anti-lock
braking capability. Installation of such equipment should be
performed by qualified professionals.
•Pumping of the Anti-Lock Brakes will diminish their effective-
ness 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.
•Anti-lock system (ABS) cannot prevent the natural laws of
physics from acting on the vehicle, nor can it increase braking or
steering efficiency beyond that afforded by the condition of the
vehicle brakes and tires or the traction afforded.
•The ABS cannot prevent accidents, including those resulting
from excessive speed in turns, following another vehicle too
closely, or hydroplaning. Only a safe, attentive, and skillful
driver can prevent accidents.
•The capabilities of an ABS equipped vehicle must never be
exploited in a reckless or dangerous manner, which could jeop-
ardize the user’s safety or the safety of others.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
Anti-Lock Brake Light
The ABS light monitors the Anti-Lock Brake Sys-
tem. The light will come on when the ignition
switch is turned to the ON position and may stay on for
as long as four seconds.
If the ABS light remains on or comes on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not come on when the
Ignition switch is turned to the ON position, have the
bulb repaired as soon as possible.

If both the Brake Warning Light and the ABS Light
remain on, the Anti-Lock brakes (ABS) and Electronic
Brake Force Distribution (EBD) systems are not function-
ing. Immediate repair to the ABS system is required.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.NOTE:Increased noise levels at the end of the steering
wheel travel are considered normal and do not indicate
that there is a problem with the power steering system.
Upon initial start-up in cold weather, the power steering
pump may make noise for a short amount of time. This is
due to the cold, thick fluid in the steering system. This
noise should be considered normal, and it does not in any
way damage the steering system.
WARNING!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.

CAUTION!
Prolonged operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and it should be avoided when
possible. Damage to the power steering pump may
occur.
MULTI DISPLACEMENT SYSTEM (MDS) — 5.7L
Engine Only
This feature offers improved fuel economy by shutting
off four of the engine’s eight cylinders during light load
and cruise conditions. The system is automatic with no
driver inputs or additional driving skills required.
NOTE:The MDS system may take some time to return
to full functionality after a battery disconnect.
TRACTION CONTROL SYSTEM (TCS) — IF
EQUIPPED
WARNING!
The Traction Control System (TCS) cannot prevent
the natural laws of physics from acting on the ve-
hicle, nor can it increase the traction afforded. The
TCS cannot prevent accidents, including those result-
ing from excessive speed in turns, or hydroplaning.
Only a safe, attentive, and skillful driver can prevent
accidents. The capabilities of a TCS-equipped ve-
hicle must never be exploited in a reckless or dan-
gerous manner, which could jeopardize the user’s
safety or the safety of others.
The Traction Control System (TCS) is standard on ve-
hicles equipped with Electronic Stability Program (ESP).
