DRIVE (D):This position is for normal driving. It
provides the best fuel economy for your vehicle. If
you need more power for passing and you are:
Going less than about 35 mph (56 km/h), push
the accelerator pedal about halfway down.
Going about 35 mph (56km/h) or more, push
the accelerator all the way down.
Downshifting the transmission in slippery road
conditions could result in skidding, see “Skidding”
underLoss of Control on page 337.
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only the
accelerator pedal may damage the
transmission. The repair will not be covered by
your warranty. If you are stuck, do not spin
the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.
Maximum engine speed is limited to protect
driveline components from improper operation.
Driver Shift Control (DSC)
The Driver Shift Control (DSC) feature lets you
manually control over the operation of the
transmission.
To use this feature,
move the shift lever from
the DRIVE (D) position
to the left and into the
driver shift control gate.

Tire Pressure Light
This light will come on
briey when you turn
the ignition on.
This light will also come on when one or more of
your tires are signicantly underinated.
A LOW TIRE PRESS DIC message will
accompany the light, seeOther Messages on
page 219for more information.Stop and check your tires as soon as it is safe to do
so. If underinated, inate to the proper pressure.
SeeTires on page 413for more information.
This light will ash for about 60 seconds and then
turn on solid if a problem is detected with the
Tire Pressure Monitor system.
SeeTire Pressure Monitor System on page 423
for more information.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which
monitors operation of
the fuel, ignition,
and emission control
systems.
196

This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable
levels for the life of the vehicle, helping to produce
a cleaner environment. The check engine light
comes on to indicate that there is a problem and
service is required. Malfunctions often will be
indicated by the system before any problem is
apparent. This may prevent more serious damage
to your vehicle. This system is also designed to
assist your service technician in correctly
diagnosing any malfunction.
Notice:If you keep driving your vehicle with
this light on, after awhile, your emission
controls may not work as well, your fuel
economy may not be as good, and your engine
may not run as smoothly. This could lead to
costly repairs that may not be covered by your
warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system
of your vehicle or the replacement of the
original tires with other than those of the sameTire Performance Criteria (TPC) can affect your
vehicle’s emission controls and may cause
this light to come on. Modications to these
systems could lead to costly repairs not
covered by your warranty. This may also result
in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 363.
This light should come on briey, as a check to
show you it is working, as you start the engine. If
the light does not come on, have it repaired.
This light will also come on during a malfunction in
one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis and
service may be required.
Light On Steady— An emission control
system malfunction has been detected on your
vehicle. Diagnosis and service may be
required.
197

FRONT Lxx Rxx PSI:This feature shows the tire
pressure for the front left and right tires.
REAR Lxx Rxx PSI:This feature shows the tire
pressure for the rear left and right tires.
OIL LIFE:This feature shows the estimated oil
life remaining. SeeOil Life Indicator on page 224
for more information. To reset the engine oil
life system, seeEngine Oil Life System on
page 380. This only needs to be reset after you
have had the oil changed.
In addition to the engine oil life system monitoring
oil life, additional maintenance is recommended
in the Maintenance Schedule in this manual.
SeeScheduled Maintenance on page 465and
Engine Oil on page 377for more information.
ENG/METRIC (English/Metric):This feature
allows you to switch the DIC displays between
English and Metric. Press the RESET button
to switch the display between English and Metric.
There will be an arrow next to the option that
is selected.DIC Warnings and Messages
These messages appear if there is a problem
detected in one of your vehicle’s systems.
You must then press RESET to clear the display
screen for further use. However, be sure to
take any message that appears on the display
screen seriously and remember that pressing the
RESET button will only make the message
disappear, not the problem.
DIC messages can also be displayed in English,
French, German, Italian, Japanese, and Spanish.
ABS (Anti-Lock Brake System)
ACTIVE
This message displays when the Anti-lock Brake
System (ABS) is adjusting brake pressure to
help avoid a braking skid.
Slippery road conditions may exist if this message
displays, so adjust your driving accordingly.
The message may stay on for a few seconds after
the system stops adjusting brake pressure.
206

Vehicle Positioning
At times, the position of the vehicle on the map
may be inaccurate due to one or more of the
following reasons:
The road system has changed.
The vehicle is driving on slippery road
surfaces such as in sand, gravel, and/or snow.
The vehicle is traveling on winding roads.
The vehicle is on a long straight road.
The vehicle is approaching a tall building or a
large vehicle.
The surface streets run parallel to a freeway.
The vehicle has just been transferred by a
vehicle carrier or a ferry.
The current position calibration is set
incorrectly.
The vehicle is traveling at high speed.
The vehicle changes directions more than
once, or when the vehicle is turning on a
turn table in a parking lot.
The vehicle is entering and/or exiting a
parking lot, garage, or a lot with a roof.
The GPS signal is not received.
A roof carrier is installed on your vehicle.
The vehicle is being driven with tire chains.
The tires are replaced.
The tire pressure for your tires is incorrect.
The tires are worn.
The rst time the map DVD is inserted.
The battery is disconnected for several days.
The vehicle is driving in heavy traffic where
driving is at low speeds, and the vehicle is
stopped and started repeatedly.
If you experience problems with your system, see
your dealer.

Control of a Vehicle
You have three systems that make your vehicle
go where you want it to go. They are the brakes,
the steering, and the accelerator. All three
systems have to do their work at the places where
the tires meet the road.
Sometimes, as when you are driving on snow or
ice, it is easy to ask more of those control systems
than the tires and road can provide. That means
you can lose control of your vehicle. SeeTraction
Control System (TCS) on page 329and
StabiliTrak
®System on page 331.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 363.
Braking
SeeBrake System Warning Light on page 192.
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake
pedal. That is perception time. Then you have to
bring up your foot and do it. That is reaction time.
Average reaction time is about three-fourths of a
second. But that is only an average. It might
be less with one driver and as long as two or
three seconds or more with another. Age, physical
condition, alertness, coordination, and eyesight
all play a part. So do alcohol, drugs, and
frustration. But even in three-fourths of a second,
a vehicle moving at 60 mph (100 km/h) travels
66 feet (20 m). That could be a lot of distance in an
emergency, so keeping enough space between
your vehicle and others is important.
And, of course, actual stopping distances vary
greatly with the surface of the road, whether it is
pavement or gravel; the condition of the road,
whether it is wet, dry, or icy; tire tread; the
condition of the brakes; the weight of the vehicle;
and the amount of brake force applied.
326

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

Try not to pass more than one vehicle at a
time on two-lane roads. Reconsider before
passing the next vehicle.
Do not overtake a slowly moving vehicle too
rapidly. Even though the brake lamps are
not ashing, it may be slowing down or starting
to turn.
If you are being passed, make it easy for the
following driver to get ahead of you. Perhaps
you can ease a little to the right.
Loss of Control
Let us review what driving experts say about what
happens when the three control systems — brakes,
steering, and acceleration — do not have enough
friction where the tires meet the road to do what the
driver has asked.
In any emergency, do not give up. Keep trying to
steer and constantly seek an escape route or
area of less danger.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking
reasonable care suited to existing conditions, and
by not overdriving those conditions. But skids
are always possible.
The three types of skids correspond to your
vehicle’s three control systems. In the braking skid,
your wheels are not rolling. In the steering or
cornering skid, too much speed or steering in a
curve causes tires to slip and lose cornering force.
And in the acceleration skid, too much throttle
causes the driving wheels to spin.
A cornering skid is best handled by easing your
foot off the accelerator pedal.
Remember: Any traction control system helps
avoid only the acceleration skid. If your traction
control system is off, then an acceleration
skid is also best handled by easing your foot off
the accelerator pedal.
337

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.
