Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.
78 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

RADIO GENERAL INFORMATION
Radio Broadcast Signals
Your new radio will provide excellent reception under
most operating conditions. Like any system, however, car
radios have performance limitations, due to mobile op-
eration and natural phenomena, which might lead you to
believe your sound system is malfunctioning. To help
you understand and save you concern about these ªap-
parentº malfunctions, you must understand a point or
two about the transmission and reception of radio sig-
nals.
Two Types of Signals
There are two basic types of radio signals... AM (Ampli-
tude Modulation), in which the transmitted sound causes
the amplitude, or height, of the radio waves to vary... and
FM (Frequency Modulation), in which the frequency of
the wave is varied to carry the sound.
Electrical Disturbances
Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.
AM Reception
AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.
FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.

either front door will cancel this feature. The time is
programmable. For details, refer to ªDelay Power Off to

252 STARTING AND OPERATING

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.
282 STARTING AND OPERATING

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) Ð 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.
STARTING AND OPERATING 283
5

This system enhances directional control and stability of
the vehicle under various driving conditions. The ESP
corrects for oversteering and understeering the vehicle
by applying the brake of the appropriate wheel. Engine
power may also be reduced to assist in counteracting the
condition of oversteer or understeer and help the vehicle
maintain the desired path.
The ESP uses sensors in the vehicle to determine the path
that the driver intends to steer the vehicle and compares
it to the actual path of the vehicle. When the actual path
does not match the intended path, the ESP applies the
brake of the appropriate wheel to assist in counteracting
the condition of oversteer or understeer.²Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
²Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
The ESP/TCS Indicator Light, located in the
instrument cluster, starts to flash as soon as the
tires lose traction and the ESP system becomes
active. The indicator light also flashes when the
TCS is active. If the indicator light begins to flash during
acceleration, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed and
driving to the prevailing road conditions.
STARTING AND OPERATING 287

Synchronizing ESP
The malfunction indicator light for the ESP is
combined with BAS indicator. If the power
supply is interrupted (battery disconnected or
discharged), the ESP/BAS malfunction indica-
tor light may illuminate with the engine running. If this
should occur, turn the steering wheel completely to the
left and then to the right. The ESP/BAS malfunction
indicator light should go out.
ESP/BAS Malfunction Indicator and ESP/TCS
Indicator Lights
The malfunction indicator light for the ESP is
combined with the BAS indicator. The yellow
ESP/BAS malfunction indicator light and the
yellow ESP/TCS indicator light in the instru-
ment cluster both come on when the ignition switch is
turned to the ªONº position. They should go out with the
engine running.The system will turn the ESP/BAS malfunction indicator
light on continuously while the engine running if it
detects a malfunction in either the ESP or the BAS or
both. If the light remains on after several ignition cycles,
and you have driven the vehicle several miles at speeds
greater than 30 mph (48 km/h), and the ESP is synchro-
nized (refer to Synchronizing ESP), see your authorized
dealer as soon as possible to have the problem diagnosed
and corrected.
