The DIC may display a CHANGE OIL NOW
message. If you see CHANGE OIL NOW, it means
the oil life is gone. For more information, see
Scheduled Maintenance on page 465andEngine
Oil on page 377.
When the oil is changed, you will need to reset
the system. SeeEngine Oil Life System on
page 380. Always keep a written record of the
mileage and date when you changed your oil.
Audio System(s)
Determine which radio your vehicle has and then
read the pages following to familiarize yourself
with its features.
Driving without distraction is a necessity for a
safer driving experience. SeeDefensive Driving on
page 322. By taking a few moments to read this
manual and get familiar with your vehicle’s audio
system, you can use it with less effort, as well
as take advantage of its features. While your
vehicle is parked, set up your audio system by
presetting your favorite radio stations, setting the
tone and adjusting the speakers. Then, whendriving conditions permit, you can tune to your
favorite stations using the presets and steering
wheel controls if the vehicle has them.
{CAUTION:
This system provides you with a far greater
access to audio stations and song listings.
Giving extended attention to entertainment
tasks while driving can cause a crash and
you or others can be injured or killed.
Always keep your eyes on the road and
your mind on the drive — avoid engaging
in extended searching while driving.
Keeping your mind on the drive is important for
safe driving. For more information, seeDefensive
Driving on page 322.

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.Your vehicle has 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 89for more information.Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft of
your vehicle’s radio. The feature works
automatically by learning a portion of the Vehicle
Identi cation Number (VIN). If the radio is
moved to a different vehicle, it will not operate. If
the radio is removed from your vehicle, the
original VIN in the radio can be used to trace the
radio back to your vehicle.
With THEFTLOCK
®activated, the radio will not
operate if stolen.

Traveling Across Regions
If you plan to drive across several states, you may
have to change the selected region to represent
the area you are traveling to.
There are two ways you can plan a destination
when traveling across regions.
The following method is suggested and provides
the most route guidance and map display
functions:
1. Change the selected search area region when
you get closer to the area you are traveling to.
See “Setting the Search Area” underMaps
on page 271.
2. Enter your destination and route settings. See
Enter Destination on page 259for more
information.
If you do not want to use the rst method, keep
your currently selected search area region
and enter your destination. This method allows
you only to select a destination from the easy
planning route method or from the All Points of
Interest (POI) categories with the “All Search
Areas” comment for US Only. For example, Touristis a category that features this comment. See
Enter Destination on page 259for more
information.
If you are traveling in or to Canada and you cross
the regional border, the only map scale views
available are 4 mi, 8 mi, 31 mi, and 128 mi (8 km,
16 km, 64 km and 256 km). Change the selected
search area region when you get closer to the area
you are traveling to. See “Setting the Search
Area” underMaps on page 271for more
information.
Keyless Access System
When the engine is started, Driver 1 or Driver 2
will display on the screen. A message will not
appear on the screen if the driver is unknown. The
number on the back of the transmitter corresponds
to driver 1 or driver 2. The navigation system
can store memory points for drivers 1 and
2 individually. SeeKeyless Access System on
page 67for more information.

Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by
heavy braking — rather than keeping pace with
traffic. This is a mistake. The brakes may not have
time to cool between hard stops. The brakes
will wear out much faster if you do a lot of heavy
braking. If you keep pace with the traffic and
allow realistic following distances, you will
eliminate a lot of unnecessary braking. That means
better braking and longer brake life.
If your vehicle’s engine ever stops while you are
driving, brake normally but do not pump the
brakes. If you do, the pedal may get harder to
push down. If the engine stops, you will still have
some power brake assist. But you will use it
when you brake. Once the power assist is used
up, it may take longer to stop and the brake pedal
will be harder to push.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modi cations on page 363.Anti-Lock Brake System (ABS)
Your vehicle has the Anti-Lock Brake System
(ABS), an advanced electronic braking system that
will help prevent a braking skid.
When you start your engine and begin to drive
away, ABS will check itself. You may hear a
momentary motor or clicking noise while this test
is going on, and you may even notice that
your brake pedal moves a little. This is normal.
If there is a problem
with ABS, this warning
light will stay on.
SeeAnti-Lock Brake
System Warning
Light on page 193.
327
Page 329 of 512
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.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down rmly and let anti-lock work for you.
You may hear a motor or clicking noise and
feel the brake pedal move a little during a stop,
but this is normal.
Braking in Emergencies
With ABS, you can steer and brake at the same
time. In many emergencies, steering can help you
more than even the very best braking.
Traction Control System (TCS)
Your vehicle has a traction control system that
limits wheel spin. This is especially useful in
slippery road conditions. The system operates only
if it senses that one or both of the rear wheels
are spinning or beginning to lose traction. When
this happens, the system works the rear brakes
and reduces engine power to limit wheel spin.
The TRAC SYSTEM ACTIVE message will display
on the Driver Information Center (DIC) when the
traction control system is limiting wheel spin.
SeeDIC Warnings and Messages on page 206.
You may feel or hear the system working, but this
is normal.
If your vehicle is in cruise control when the
traction control system begins to limit wheel spin,
the cruise control will automatically disengage.
When road conditions allow you to safely
use it again, you may reengage the cruise control.
SeeAdaptive Cruise Control on page 150or
Cruise Control on page 147for 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 has 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.
The traction you can get in a curve depends on
the condition of the tires and the road surface, the
angle at which the curve is banked, and your
speed. While you are in a curve, speed is the one
factor you can control.
Suppose you are steering through a sharp curve.
Then you suddenly accelerate. Both control
systems — steering and acceleration — have to
do their work where the tires meet the road.
Adding the sudden acceleration can demand too
much of those places. You can lose control.
SeeTraction Control System (TCS) on page 329.
What should you do if this ever happens? Ease
up on the accelerator pedal, steer the vehicle the
way you want it to go, and slow down.
Speed limit signs near curves warn that you
should adjust your speed. Of course, the posted
speeds are based on good weather and road
conditions. Under less favorable conditions you will
want to go slower.
333
Page 338 of 512
If your vehicle starts to slide, ease your foot off
the accelerator pedal and quickly steer the
way you want the vehicle to go. If you start
steering quickly enough, your vehicle may
straighten out. Always be ready for a second skid
if it occurs.
Of course, traction is reduced when water, snow,
ice, gravel, or other material is on the road.
For safety, you will want to slow down and adjust
your driving to these conditions. It is important
to slow down on slippery surfaces because
stopping distance will be longer and vehicle control
more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration, or
braking, including reducing vehicle speed by
shifting to a lower gear. Any sudden changes could
cause the tires to slide. You may not realize the
surface is slippery until your vehicle is skidding.
Learn to recognize warning clues — such as
enough water, ice, or packed snow on the road to
make a mirrored surface — and slow down when
you have any doubt.
Remember: Any Anti-Lock Brake System (ABS)
helps avoid only the braking skid.Racing or Other Competitive
Driving (XLR-V)
See your warranty book before using your vehicle
for racing or other competitive driving.
Notice:If you use your vehicle for racing or
other competitive driving, the engine may
use more oil than it would with normal use.
Low oil levels can damage the engine. Be sure
to check the oil level often during racing or
other competitive driving and keep the level at
or near 2 quarts (2 L) above the upper mark
that shows the proper operating range on the
engine oil dipstick. For information on how
to add oil, seeEngine Oil on page 377.
After the competitive driving, remove excess
oil so that the level on the dipstick is not above
the upper mark that shows the proper
operating range.

Driving Through Deep Standing Water
Notice:If you drive too quickly through
deep puddles or standing water, water can
come in through your engine’s air intake and
badly damage your engine. Never drive through
water that is slightly lower than the underbody
of your vehicle. If you cannot avoid deep
puddles or standing water, drive through them
very slowly.
Driving Through Flowing Water
{CAUTION:
Flowing or rushing water creates strong
forces. If you try to drive through owing
water, as you might at a low water
crossing, your vehicle can be carried
away. As little as six inches of owing
water can carry away a smaller vehicle.
CAUTION: (Continued)
CAUTION: (Continued)
If this happens, you and other vehicle
occupants could drown. Do not ignore
police warning signs, and otherwise be
very cautious about trying to drive
through owing water.
Some Other Rainy Weather Tips
Besides slowing down, allow some extra
following distance. And be especially careful
when you pass another vehicle. Allow yourself
more clear room ahead, and be prepared to
have your view restricted by road spray.
Have good tires with proper tread depth. See
Tires on page 413.
342
Page 345 of 512
Once you are moving on the freeway, make
certain you allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your
exit, do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite
sharply. The exit speed is usually posted. Reduce
your speed according to your speedometer, not
to your sense of motion. After driving for any
distance at higher speeds, you may tend to think
you are going slower than you actually are.Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested. If
you must start when you are not fresh — such
as after a day’s work — do not plan to make too
many miles that rst part of the journey. Wear
comfortable clothing and shoes you can easily
drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it
needs service, have it done before starting out. Of
course, you will nd experienced and able
service experts in GM dealerships all across North
America. They will be ready and willing to help
if you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir
full? Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
Lamps:Are they all working? Are the lenses
clean?
