Memory (Option)
MEMORY can store and recall the settings for the
driver's seat position, the outside rearview mirror
positions, comfort control temperature, fan speed and
mode settings, telescopic steering wheel (if equipped),
radio presets, tone, volume, playback mode
(AM/FM, tape or CD), last displayed station,
compact disc position and tape direction.
The MEMORY buttons are located on the driver's side
door, above the power mirror controls. The MEMORY
buttons can store and recall settings for up to three drivers.Use button ª1º to store the settings for the first driver, button
ª2º for a second driver or press buttons 1 and 2 at the same
time for a third driver. To store your memory settings:
1. Adjust your settings for the driver's seat position,
outside rearview mirror positions, comfort control
temperature, fan speed, mode settings and telescopic
steering wheel (if equipped).
2. Press and hold a MEMORY button. The light above
the MEMORY button will glow steady for one
second and then flash once when the settings are
complete. Then the light will go off.
3. Set the radio presets, tone, volume, playback mode
(AM/FM, tape or CD), tape direction and compact
disc position.
Your memory settings are now programmed. Any
changes that are made to the audio system while driving
are automatically stored.
When first entering your vehicle, after pressing the
UNLOCK button on your key fob transmitter or a
MEMORY button, a recall of your settings will occur
when the ignition key is inserted. As the memory
settings are recalled, the light above the button will flash
until the correct settings are achieved, then glow for five
seconds when complete.

A memory recall can be stopped by pressing any memory
seat, mirror or steering column position button.
Drivers 1, 2 and 3 correspond to the order in which your
key fob transmitters were programmed. (See ªFob
Trainingº in the Index.)
Memory recall will not work if the vehicle is moving,
the key is removed from the ignition, the driver's door is
open, a power seat, mirror or memory switch is being
used. Memory recall will be temporarily interrupted
during engine crank.
Remote Function Actuation System
Your vehicle has a passive/active Remote Function
Actuation (RFA) system that allows you to lock and
unlock your doors, unlock your hatch/trunk lid, turn
the panic alarm on and off and disarm or arm your
theft
-deterrent system. When using one of the key fob
transmitters supplied with your vehicle, the passive
range distance is as much as 30 feet (9 m) away from the
vehicle on the driver's side and 20 feet (6 m) away on
the passenger's side. The active range distance is as
much as 100 feet (30 m) away.
Your vehicle comes
standard with two
transmitters, and up to
three can be matched to
your vehicle.
See ªMatching Transmitter(s) to Your Vehicleº later in
this section.
Your RFA system operates on a radio frequency subject
to Federal Communications Commission (FCC) Rules
and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received,
including interference that may cause
undesired operation.

Front Air Dam
Your vehicle is equipped with a front air dam which has
minimal ground clearance for aerodynamics. For this
reason, the air dam has a spring
- loaded hinge provided
and it will retract with road contact.
In normal operation, the air dam will occasionally
contact some road surfaces (speed bumps, driveway
ramps, etc.). This can be heard inside the vehicle as a
scraping noise. This is normal and does not indicate
a problem.
Use care when approaching bumps or objects on road
surfaces and avoid them when possible.
Ignition Positions
CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons. A child or
others could be injured or even killed. They could
operate power windows or other controls or even
make the vehicle move. Don't leave the keys in
the vehicle with children.
With the key in the ignition
switch, you can turn the
switch to four positions.
OFF: The only position from which you can remove the
key. Removing the key locks your steering wheel,
ignition and automatic transmission.
If you have an automatic transmission, the ignition
switch can't be turned to OFF unless the shift lever is
in PARK (P).

ACC: This is an on position in which you can operate
your electrical power accessories. With the key in this
position, the automatic transmission and steering
column will unlock.
ON: This is the position to which the switch returns
after you start the engine and release the switch. The
switch stays in ON when the engine is running. But even
when the engine is not running, you can use ON to
operate your electrical power accessories and to display
some instrument panel messages and telltales.
START: This position starts the engine. When the
engine starts, release the key. The ignition switch will
return to ON for normal driving.
When the engine is not running, ACC and ON allow you
to operate your electrical accessories, such as the radio.
A warning tone will sound if you open the driver's door
when the ignition is in OFF or ACC and the key is in
the ignition.
CAUTION:
Removing the key from the ignition switch will
lock the steering column and result in a loss of
ability to steer the vehicle. This could cause a
collision. If you need to turn the engine off while
the vehicle is moving, turn the key to ACC.
NOTICE:
If your key seems stuck in OFF and you can't
turn it, be sure you are using the correct key; if
so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break
the key or the ignition switch. If none of this
works, then your vehicle needs service.

FOB TRAINING: This option allows you to match the
RFA transmitter(s) to your vehicle. You can access this
option by pressing and holding RESET for three
seconds while you are on the blank page at the end of
the OPTIONS menu. The message FOB TRAINING
will be displayed. See ªMatching Transmitter(s) To Your
Vehicleº in the Index for more information.
TIRE TRAINING: The Tire Pressure Monitor (TPM)
operates with battery-powered sensors that are located
inside the valve stems on each tire. Each sensor has a
unique ID code so the vehicle knows the tire location of
the sensor. When the vehicle reaches a speed of greater
than 15 mph (24 km/h), the sensors begin to send the
tire pressure readings to a receiver inside the vehicle.
These readings are displayed when using the GAGES
button on the DIC. If you are unable to display your tire
pressures while the vehicle speed is greater than 15 mph
(24 km/h), you may need to have your sensor ID codes
learned by the vehicle. See your dealer.

SERVICE COLUMN LOCK: If the system that
controls the locking and unlocking of the steering
column does not work properly, have the vehicle towed
to a dealer for service.
PULL KEY
- WAIT 10 SEC: If this message comes
on, the steering column lock system has detected a
problem while engaging the steering column lock. This
message may occur when the ignition key is removed
and re
-inserted before the steering column lock system
fully locks or unlocks the steering column. To
acknowledge that you have read this message, and to
clear it from the display, remove the ignition key and
wait 10 seconds before re
-inserting the key into the
ignition. If you attempt to operate your vehicle without
removing the key for 10 seconds, the vehicle's fuel
system will shut off at 1.5 mph (2.4 km/h). If the
message stays on after removing the key and waiting 10
seconds, have your vehicle taken to an authorized dealer
as soon as possible for diagnosis and repair.
LOW OIL PRESSURE: You will hear four chimes and
the CHECK GAGES telltale will come on when this

press the RESET button. After you press the RESET
button, a message will be displayed and you will hear a
chime every minute until the vehicle is serviced. If you
do not press RESET, the message will remain on the
digital display until the vehicle is serviced.Low oil pressure may be the result of a combination of
low oil level and abrupt changes in the vehicle's
direction. When this warning is displayed, you should
not operate the engine at high RPM or make fast abrupt
moves. When it is convenient, you should check the oil
level. See ªEngine Oilº in the Index.
LOW OIL LEVEL: Press RESET to acknowledge that
you have read the message and to remove it from the
display. The message will reappear every 10 minutes
until this condition changes.
You will hear two chimes when this message is
displayed. If this message appears after starting your
engine, your engine oil level may be too low. You may
need to add oil. See ªEngine Overheatingº in the Index.
REDUCED ENGINE POWER: You will hear
chimes continuously when this message is displayed.
To acknowledge that you have read the message and
to remove it from the display, press RESET. The
message will reappear every 15 seconds until this

4-12 Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
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.
Magnasteer

Your vehicle is equipped with GM Magnasteer, a
steering system that continuously adjusts the effort you
feel when steering at all vehicle speeds. It provides ease
when parking yet a firm, solid feel at highway speeds.
Steering Tips
Driving on Curves
It's important to take curves at a reasonable speed.
A lot of the ªdriver lost controlº accidents mentioned on
the news happen on curves. Here's 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's no traction, inertia will keep
the vehicle going in the same direction. If you've ever
tried to steer a vehicle on wet ice, you'll 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're in a curve, speed is the one factor you
can control.
Suppose you're 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. Refer to ªTraction
Control Systemº in the Index.
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'll want to go slower.
