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 “ap-
parent” 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 or
Amplitude Modulation, in which the transmitted sound
causes the amplitude, or height, of the radio waves to
vary... and FM or 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.
NOTE:For vehicles not equipped with the Electronic
Vehicle Information Center (EVIC), the radio, steering
wheel radio controls (if equipped), and 6 disc CD/DVD
changer (if equipped) will remain active for 10 minutes
after the ignition switch is turned off. Opening either
front door will cancel this feature.

hicle Information Center (EVIC), the radio, steering

232 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 ElectronicBrake 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
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.
256 STARTING AND OPERATING
The Brake Assist System (BAS) is standard on vehicles
equipped with Electronic Stability Program (ESP). The
BAS is designed to optimize the vehicle’s braking capa-
bility during emergency braking maneuvers. The system
applies optimum pressure to the brakes in emergency
braking conditions than might otherwise be afforded
solely by the driver’s braking style. This can help reduce
braking distances. The BAS complements the Anti-Lock
Brake System (ABS). Applying the brakes very quickly
results in the best BAS assistance. To receive the benefit of
the system, you must apply continuous braking power
during the stopping sequence. Do not reduce brake pedal
pressure. Once the brake pedal is released, the BAS is
deactivated.ELECTRONIC STABILITY PROGRAM (ESP) — IF
EQUIPPED
WARNING!
The ESP (Electronic Stability Program) cannot pre-
vent the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. The ESP cannot prevent
accidents, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of an
ESP-equipped vehicle must never be exploited in a
reckless or dangerous manner, which could jeopar-
dize the user’s safety or the safety of others.
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
STARTING AND OPERATING 259

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.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Understeer - 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.The ESP OFF button is located in the center of the
instrument panel. To turn OFF the ESP, momentarily
press the ESP OFF button and the ESP/TCS indicator
light will illuminate. To turn the system ON again,
momentarily press the ESP OFF button and the indicator
light will turn OFF.
NOTE:To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand, or
gravel, switch off the ESP by pressing the ESP OFF
button.
260 STARTING AND OPERATING
When ESP is switched off, the engine torque reduction
feature is cancelled. Therefore, the enhanced vehicle
stability offered by ESP is unavailable. However, a fea-
ture of the system remains active. This feature controls
wheel spin across an axle quite similarly to a limited slip
differential. If one wheel on an axle is spinning faster
than the other, the system will apply the brake of the
spinning wheel and allow more engine torque to be
applied to the wheel that is not spinning. This wheel slip
control is active at vehicle speeds between approximately
24 mph (40 km/h) and 50 mph (80 km/h).
CAUTION!
When the ESP/TCS indicator light is illuminated
continuously, the ESP is switched off. Avoid spin-
ning one drive wheel. This may cause serious dam-
age to the drive train.
CAUTION!
If the vehicle is towed with the front axle raised, the
engine must be shut off (key in the ignition switch to
the OFF/LOCK or ACC position). Otherwise, the ESP
will immediately be engaged and will apply the rear
wheel brakes.
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. However, if the light
remains on, have the ESP and BAS checked at your
authorized dealer as soon as possible.
