LOW OIL PRESSURE:If this message appears while
the engine is running, stop the engine and do not
operate it until the cause of low oil pressure is corrected.
Severe damage to the engine can result. A multiple
chime will sound when this message is displayed. See
Engine Oil on page 5-16.

and the tire pressure light on the instrument panel
cluster will come on when this message is displayed.
SeeTire Pressure Light on page 3-42. To acknowledge
the warning, press the RESET button. After you
press the RESET button, a message will appear every
10 minutes until this condition changes. This message
indicates that the pressure in one of your tires is
less than 24 psi (164 kPa). Next to the LOW TIRE
PRESSURE message, you can see either LEFT
FRONT, RIGHT FRONT, LEFT REAR, or RIGHT REAR

{CAUTION:
When the LOW TIRE PRESSURE or TIRE FLAT
message is displayed on the Driver Information
Center, your vehicle’s handling capabilities will
be reduced during severe maneuvers. The
active handling system will be affected. See
Active Handling System on page 4-10.Ifyou
drive too fast, you could lose control of your
vehicle. You or others could be injured. Do not
drive over 55 mph (90 km/h) when the LOW
TIRE PRESSURE or TIRE FLAT message is
displayed. Drive cautiously and check your tire
pressures as soon as you can.

Here are some ways in which you can help avoid
distraction while driving.
While your vehicle is parked:
Familiarize yourself with all of its controls.
Familiarize yourself with its operation.
Set up your audio system by presetting your
favorite radio stations, setting the tone, and
adjusting the speakers. Then, when driving
conditions permit, you can tune to your favorite
radio stations using the presets and steering wheel
controls if the vehicle has them.
Notice:Before adding any sound equipment to
your vehicle, such as an audio system, CD player,
CB radio, mobile telephone, or two-way radio, make
sure that it can be added by checking with your
dealer. Also, check federal rules covering mobile
radio and telephone units. If sound equipment can
be added, it is very important to do it properly.
Added sound equipment may interfere with
the operation of your vehicle’s engine, radio, or
other systems, and even damage them. Your
vehicle’s systems may interfere with the operation
of sound equipment that has been added.Notice:The chime signals related to safety belts,
parking brake, and other functions of your vehicle
operate through the radio/entertainment system.
If that equipment is replaced or additional equipment
is added to your vehicle, the chimes may not
work. Make sure that replacement or additional
equipment is compatible with your vehicle before
installing it. SeeAccessories and Modifications
on page 5-3.
Your vehicle may have a feature called Retained
Accessory Power (RAP). With RAP, the audio system
can be played even after the ignition is turned off.
SeeRetained Accessory Power (RAP) on page 2-23
for more information.
Setting the Time
With the ignition on and the radio off, press the H or the
M button to enter clock mode. Press and hold H until
the correct hour appears on the display. Press and
hold M until the correct minute appears on the display.
To change the time default setting from 12 hour to
24 hour, press either the H or the M button for
two seconds to enter the clock mode. Press the tune
knob to select between the 12 or 24 hour display format.
The clock mode will automatically time out with the
changed display format set as the current default setting.

Care of the CD Player
The use of CD lens cleaners for CD players is not
advised, due to the risk of contaminating the internal
lens of the CD optics with lubricants.
Diversity Antenna System
The AM-FM antenna is a hidden self tuning system. It
optimizes the AM and FM signals relative to the vehicle’s
position and radio station source. No maintenance or
adjustments are needed.
XM™ Satellite Radio Antenna
System (Roof or Trunk Mounted)
The XM™ Satellite Radio antenna is located on the roof
or on the trunk lid of your vehicle. Keep this antenna
clear of snow and ice build up for clear radio reception.
XM™ Satellite Radio Antenna
System (Diversity System)
Your vehicle may have the XM™ Satellite Radio
antennas that are located in the outside rear view
mirrors. These antennas are hidden from view and are
not accessible.
Chime Level Adjustment
The radio is used to adjust the vehicle’s chime level.
To change the volume level of the chime, press and hold
pushbutton 6 with the ignition on and the radio power off.
The volume level will change from the normal level to
loud, and LOUD will appear on the radio display. To
change back to the default or normal setting, press and
hold pushbutton 6 again. The volume level will change
from the loud level to normal, and NORMAL will appear
on the radio display. Only one chime will be heard when
changing from the normal to the loud setting. Each time
the chime volume is changed, three chimes will sound as
an example of the new volume selected. Removing the
radio and not replacing it with a factory radio or chime
module will disable vehicle chimes.

Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel.
ABS can change the brake pressure faster than any
driver could. The computer is programmed to make the
most of available tire and road conditions. This can
help you steer around the obstacle while braking hard.As you brake, your computer keeps receiving updates
on wheel speed and controls braking pressure
accordingly.
Remember: ABS does not change the time you need to
get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle
in front of you, you will not have time to apply your
brakes if that vehicle suddenly slows or stops. Always
leave enough room up ahead to stop, even though
you have ABS.

This knob is located on the
center console. Turn it to
select the suspension
of your choice.
TOUR:Use for normal city and highway driving. This
setting provides a smooth, soft ride.
SPORT:Use where road conditions or personal
preference demand more control. This setting provides
more “feel”, or response to the road conditions.
You can select a setting at any time. Based on road
conditions, steering wheel angle and your vehicle speed,
the system automatically adjusts to provide the best
ride and handling. Select a new setting whenever driving
conditions change.
There are three Driver Information Center (DIC)
messages that are displayed when a malfunction occurs
with the Selective Ride Control system (SERVICE
RIDE CONTROL, SHOCKS INOPERATIVE, MAXIMUM
SPEED 80 MPH (129 KM/H). Refer toDIC Warnings
and Messages on page 3-53for more information.Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer
but it will take much more effort.
Magnetic Speed Variable Assist
Steering
Your vehicle is equipped with a steering system that
continuously adjusts the effort you feel when steering
at all vehicle speeds. It provides ease when parking,
yet a rm, solid feel at highway speeds.
Steering Tips
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here is why:
Experienced driver or beginner, each of us is subject
to the same laws of physics when driving on curves.
The traction of the tires against the road surface makes
it possible for the vehicle to change its path when
you turn the front wheels. If there is no traction, inertia
will keep the vehicle going in the same direction. If
you have ever tried to steer a vehicle on wet ice, you
will understand this.
