Steering Column Ignition Lock Release
If your vehicle has a dead battery or a battery with
low voltage, you can still release the ignition lock and
remove the key. Use the following procedure to release
the steering column:
1. Locate the plastic screw head on the underside of
the plastic cover for the steering column.
2. Insert a at, thin object into the slot and turn it until
the plastic piece detaches from the steering column
cover.3. Insert a narrow, pointed object into the hole in the
steering column cover and press the spring.
4. Then, turn the ignition switch to OFF and remove
the key.
Retained Accessory Power (RAP)
The following accessories on your vehicle may be used
for up to 10 minutes after the ignition key is turned
from ON to OFF:
Radio
Power Windows
Audio Steering Wheel Controls
Sunroof
Power to these accessories stops after 10 minutes or if
a door is opened. If you want power for another
10 minutes, close all the doors and turn the ignition key
to ON and then back to OFF.

2. Press the shift lever forward to upshift or rearward
to downshift.
The odometer on the instrument panel cluster will
change from the mileage to a number indicating the
requested gear range when moving the shift
lever forward or rearward. SeeSpeedometer and
Odometer on page 3-36for more information on the
odometer.
While using the DSC feature the vehicle will have rmer
shifting and increased performance. You can use this
for sport driving or when climbing/descending hills
to stay in gear longer or to down shift for more power or
engine braking.
The transmission will only allow you to shift into gears
appropriate for the vehicle speed and engine
Revolutions Per Minute (RPM). The transmission will
not automatically shift to the next higher gear if the
engine rpm is too high.
If shifting is prevented for any reason, the currently
selected gear will ash multiple times, indicating that the
transmission has not shifted gears.
The transmission will allow you to shift to the gear
selected and will automatically downshift when
the vehicle comes to a stop. This will allow for more
power during take-off and passing.When accelerating your vehicle from a stop in snowy
and icy conditions, you may want to shift into second
gear. A higher gear ratio allows you to gain more traction
on slippery surfaces.
Parking Brake
The parking brake pedal is
located on the lower
portion of the instrument
panel to the left of the
steering wheel.
To set the parking brake, hold the regular brake pedal
down with your right foot and push the parking brake
pedal down with your left foot.
If the ignition is on, the brake system warning light on
the instrument panel cluster should come on. If it
does not, you need to have your vehicle serviced. See
Brake System Warning Light on page 3-39for more
information.

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

Radio Reception
You may experience frequency interference and static
during normal radio reception if items such as cellphone
chargers, vehicle convenience accessories, and
external electronic devices are plugged into the
accessory power outlet. If there is interference or static,
unplug the item from the accessory power outlet.
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range can cause
station frequencies to interfere with each other. For
better radio reception, most AM radio stations will boost
the power levels during the day, and then reduce
these levels during the night. Static can also occur when
things like storms and power lines interfere with radio
reception. When this happens, try reducing the treble on
your radio.

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. SeeStabiliTrak
®System on
page 4-11.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modi cations
on page 5-3.
Braking
SeeBrake System Warning Light on page 3-39.
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 ormore 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 your brakes;
the weight of the vehicle; and the amount of brake
force applied.
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. Your brakes may not have time to cool
between hard stops. Your 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 engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do,
the pedal may get harder to push down. If your 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.

All-Wheel Drive (AWD) System
If your vehicle is equipped with this feature, engine
power is sent to all four wheels all the time. This is like
four-wheel drive, but it is fully automatic.
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.
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 your 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. SeeStabiliTrak
®System
on page 4-11.
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.
If you have StabiliTrak
®, you may see the STABILITY
SYSTEM ACTIVE message on the message center. See
“Stability System Active Message” underDIC Warnings
and Messages on page 3-59.
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.
If you need to reduce your speed as you approach
a curve, do it before you enter the curve, while your front
wheels are straight ahead.
4-12
Approaching a Hill
When you approach a hill, you need to decide if it is
one of those hills that is just too steep to climb, descend,
or cross. Steepness can be hard to judge. On a very
small hill, for example, there may be a smooth, constant
incline with only a small change in elevation where
you can easily see all the way to the top. On a large hill,
the incline may get steeper as you near the top, but
you may not see this because the crest of the hill
is hidden by bushes, grass, or shrubs.
Here are some other things to consider as you
approach a hill.
Is there a constant incline, or does the hill get
sharply steeper in places?
Is there good traction on the hillside, or will the
surface cause tire slipping?
Is there a straight path up or down the hill so you
will not have to make turning maneuvers?
Are there obstructions on the hill that can block your
path, such as boulders, trees, logs, or ruts?
What is beyond the hill? Is there a cliff, an
embankment, a drop-off, a fence? Get out and
walk the hill if you do not know. It is the smart way
to nd out.
Is the hill simply too rough? Steep hills often have
ruts, gullies, troughs, and exposed rocks because
they are more susceptible to the effects of erosion.
Driving Uphill
Once you decide you can safely drive up the hill, you
need to take some special steps.
Use a low gear and get a rm grip on the steering
wheel.
Get a smooth start up the hill and try to maintain
your speed. Do not use more power than you
need, because you do not want your wheels to start
spinning or sliding.
Try to drive straight up the hill if at all possible. If
the path twists and turns, you might want to nd
another route.
{CAUTION:
Turning or driving across steep hills can be
dangerous. You could lose traction, slide
sideways, and possibly roll over. You could be
seriously injured or killed. When driving up
hills, always try to go straight up.
