Cruise control can be dangerous where you
can’t drive safely at a steady speed.
So,
don’t use your cruise control on winding
roads or in heavy traffic. Cruise control can be dangerous on
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don’t
use cruise control on slippery roads.
~~~ ~~ ~
If your vehicle is in cruise control when the optional
traction control system begins to limit wheel spin, the
cruise control will automatically disengage. (See
“Traction Control System”
in the Index.) When road
conditions allow you
to safely use it again, you may turn
the cruise control back
on.
Setting Cruise Control
I A CAUTION:
If you leave your cruise control
you’re not using cruise, you might hit a button
and go into cruise when you don’t want
to. You
could be startled and even lose control. Keep the
cruise control switch off until you want
to use it.
1. Move the cruise control
switch to
ON.
2. Get up to the speed you want.

Anti-Lock Brake System Warning Light
With the anti-lock brake
system, the light(s) will
come on when you start
your engine and may stay
on for several seconds.
That’s normal.
If the light stays on and the chime sounds, turn the
ignition to
OFF. Or, if the light comes on and the chime
sounds when you’re driving, stop as soon as possible
and turn the ignition
off. Then start the engine again to
reset the system. If the light still stays on and the chime
sounds, or the light comes on again while you’re
driving, your Buick needs service.
If the regular brake
system warning light isn’t on, you still have brakes,
but you don’t have anti-lock brakes. If the regular
brake system warning light is also on, you don’t have
anti-lock brakes and there’s a problem with your regular
brakes. See “Brake System Warning Light” earlier in
this section. The
anti-lock brake system warning light should come
on briefly when you turn the ignition
key to RUN. If the
light doesn’t
come on then, have it fixed so it will be
ready
to warn you if there is a problem.
Traction Control System Warning Light
(Option)
TRAC
OFF
This warning light should
come
on briefly as you start
the engine. If the warning
light doesn’t come
on then,
have it fixed
so it will be
ready to warn you if there’s
a problem.
If it stays on, or comes on when you’re driving, there
may be a problem with your traction control system and
your vehicle may need service. When this warning light
is on, the system will not limit wheel spin. Adjust your
driving accordingly.

If there’s a brake system problem that
is specifically
related
to traction control, the traction control system
will turn
off, the warning light will come on and the
chime will sound.
If the traction control system is affected by an
engine related problem, the system will turn off,
the warning light will come on and the chime
will sound.
If the traction control system warning light comes on
and stays on for an extended period
of time when the
system
is turned on, your vehicle needs service.
Engine Coolant Temperature Gage
TEMPERATURE
This gage measures the
temperature of your engine.
If the pointer moves into the
red area, your engine is too
hot.
A temperature indicator
light will turn on and a
chime will sound.
If you have been operating your vehicle under normal
driving conditions and the temperature indicator light
turns on, you should pull off the road, stop your vehicle
and turn off the engine as soon as possible.
The section “Problems on the Road,” in this manual
explains what to do. See “Engine Overheating” in
the Index.

Personal Choice Programming
The DIC can be used to program personal choice
features available with your vehicle, such as memory
seats, memory door locks, security feedback, delayed
locking and perimeter lighting. See “Personal Choice
Features” in the Index.
The DIC is used to program the personal choices of
two drivers. The driver’s are recognized by DRIVER
#1
and DRIVER #2. You will let the DIC know which
driver you are by using your Remote Keyless Entry
transmitter or by pressing the appropriate memory
seat control button located on the driver’s door. The
remote transmitter was pre-programmed to belong
to
DRIVER #1 or DRIVER #2.
The last driver number remembered by the DIC will show
on the display each time the UNLOCK button on the same
transmitter is pressed, and the ignition is turned on.
When you press UNLOCK on your transmitter, the DIC
will automatically change driver numbers and the
vehicle will recall the personal choice settings that were
last made to correspond to your transmitter.

Remember: Anti-lock doesn’t 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 won’t 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
anti-lock brakes.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down and let anti-lock work for you. You may feel the system
working, or you may notice some noise, but this is normal.
Traction Control System (If Equipped)
Your vehicle may have 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 front wheels are spinning or
beginning to lose traction. When this happens, the
system works the front brakes and reduces engine power
to
limit wheel spin.
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
re-engage the cruise control. (See “Cruise Control” in
the Index.)
TRAC
OFF
When the system is on, this
warning light will come on
to let you know if there’s
a
problem with your traction
control system.
I
See “Traction Control System Warning Light” in the
Index. When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
The traction control system automatically comes on
whenever you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off
if you ever need to. (You
should turn the system off if your vehicle ever gets stuck
in sand, mud, ice or snow. See “Rocking Your Vehicle”
in the Index.)

To turn the system off, press the button located at the
end of the shift lever.
The traction control system warning light will come on
and stay on. If the system is limiting wheel spin when
you press the button, the warning light will come on
--
but the system won’t turn off right away. It will wait
until there’s no longer a current need to limit wheel spin.
You can turn the system back on at any time by pressing
the button again. The traction control system warning
light should go off.
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 (If Equipped)
Your vehicle may be equipped with GM Magnasteer TM,
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.
Your steering can be adjusted for an easier or more firm
setting. See your dealer for information.

Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control” 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
“Traction Control” 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.
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.
Try to adjust your speed
so you can “drive” through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until you are out of the curve, and then
accelerate gently into the straightaway.

Loss of Control
Let’s review what driving experts say about what
happens when the three control systems (brakes, steering
and acceleration) don’t have enough friction where the
tires meet the road to do what the driver has asked.
In any emergency, don’t 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 sluds correspond to your Buick’s
three control systems. In the braking skid, your wheels
aren’t 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.
If you have the traction control system, remember: It
helps avoid only the acceleration skid. If you
do not have traction control, or if the system is
off, then an acceleration skid is also best handled by
easing your foot off the accelerator pedal.
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’ll
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 engine braking 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
shd.

Driving on Snow or Ice
Most of the time, those places where your tires meet the
road probably have
good traction.
However,
if there is snow or ice between your tires and
the road, you can have a very slippery situation. You’ll
have a lot less traction or “grip” and will need to be
very careful.
............ ...I ........ _ ................
.-- --
.............. ..- ........... < .... I .......... ’.rJ>‘.;
What’s the worst time for this? “Wet ice.” Very cold
snow or ice can be slick and hard to drive on. But wet
ice can be even more trouble because it may offer the
least traction of all. You can get wet ice when it’s about
freezing
(32°F; 0” C) and freezing rain begins to fall.
Try to avoid driving on wet ice until salt and sand crews
can get there.
Whatever the condition
-- smooth ice, packed, blowing
or loose snow
-- drive with caution.
If you have traction control, keep the system on. It will
improve your ability to accelerate when driving on a
slippery road. Even
though your vehicle has a traction
control system, you’ll want to slow down and adjust
your driving to the road conditions. See “Traction
Control System’’ in the Index.
If you don’t have the traction control system, accelerate
gently. Try not to break the fragile traction.
If you
accelerate too fast, the drive wheels will spin and polish
I the surface under the tires even more.
