Horn
Press near or on the horn symbols on your steering
wheel pad to sound the horn.
Tilt Wheel
A tilt steering wheel allows you to adjust the steering
wheel before you drive. You can raise the steering wheel
to the highest level to give your legs more room when
you exit and enter. The lever to adjust it is located on the
left side of the steering column.
To adjust the wheel, hold
the steering wheel and pull
the lever. Move the
steering wheel to a
comfortable level, then
release the lever to
lock the wheel into place.
Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
·Turn Signal and Lane-Change Indicator
·Headlamp High/Low-Beam Changer
·Flash-to-Pass
·Windshield Wipers
·Windshield Washer
·Cruise Control
For more information on the exterior lamps, see
Exterior
Lamps on page 3-14later in this section.

Cruise Control
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. This can really help on long
trips. Cruise control does not work at speeds below
about 25 mph (40 km/h).
When you apply your brakes, the cruise control
shuts off.
{CAUTION:
·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 traction
control system (option) begins to limit wheel spin, the
cruise control will automatically disengage. See
Traction
Control System (TCS) (3800 V6 Engine) on page 4-9.
When road conditions allow you to safely use it
again, you may turn the cruise control back on.
Setting Cruise Control
The cruise control ON/OFF switch is located at the end
of the multifunction lever.
{CAUTION:
If you leave your cruise control on when 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
cruise control.
1. Slide the cruise control ON lever on the turn signal
lever to the right to turn it on.
2. Get up to the speed you want.
3-11

3. Press the SET button
located on the steering
wheel and release it.
4. Take your foot off the accelerator.
The CRUISE light on the instrument panel cluster will
come on after the cruise control has been set to
the desired speed.Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course shuts
off the cruise control. But you don't need to reset it.
Once you're going about
25 mph (40 km/h) or more,
press the RESUME
button on your steering
wheel. You'll go right back
up to your chosen
speed and stay there.
3-12

Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
·Use the accelerator pedal to get to the higher
speed. Press the SET button on the steering wheel,
then release the button and the accelerator pedal.
You'll now cruise at the higher speed.
·Press the ACCEL (Accelerate) button on the
steering wheel. Hold it there until you get up to the
speed you want and then release the button.
(To increase your speed in very small amounts,
press the ACCEL button brie¯y and then release it.
Each time you do this, your vehicle will go about
1 mph (1.6 km/h) faster).
The accelerate feature will only work after you set the
cruise control speed by pressing the SET button on the
steering wheel.
Reducing Speed While Using Cruise
Control
There are two ways to reduce your speed while using
cruise control:
·Press the COAST button on the steering wheel
until you reach the lower speed you want, then
release it.
·To slow down in very small amounts, press the
COAST button on the steering wheel brie¯y.
Each time you do this, you'll go about 1 mph
(1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise speed you set earlier.
3-13

Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may have to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control. Many
drivers ®nd this to be too much trouble and don't use
cruise control on steep hills.
Ending Cruise Control
There are three ways to cancel the cruise control:
·Step lightly on the brake pedal.
·Slide the lever on the multifunction lever to the left
to the OFF position.
·Press the COAST and ACCEL buttons at the
same time.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
Exterior Lamps
The exterior lamps control
is located on the
instrument panel to the left
of the steering wheel.
It controls the following systems:
·Headlamps
·Taillamps
·Parking Lamps
·License Plate Lamps
·Instrument Panel Lights

If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
your dealer can check the vehicle. Your dealer has
the proper test equipment and diagnostic tools to ®x any
mechanical or electrical problems that may have
developed.
Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the Check
Engine light is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system isdesigned to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.
Cruise Control Light
Tthe CRUISE light comes
on whenever you set your
cruise control. See
ªCruise Controlº under
Turn Signal/Multifunction
Lever on page 3-7.
3-39

Traction Control System (TCS)
(3800 V6 Engine)
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 reduces
engine power and may also upshift the transaxle and
apply the front brakes to limit wheel spin.
This light will come on when your traction control
system is limiting wheel spin. See
Traction Active
Message on page 3-41.
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 roadconditions allow you to safely use it again, you may
re-engage the cruise control. See ªCruise Controlº
in
Turn Signal/Multifunction Lever on page 3-7.
The traction control system operates in all transaxle
shift lever positions. But the system can upshift
the transaxle only as high as the shift lever position
you've chosen, so you should use the lower gears only
when necessary. See
Automatic Transaxle Operation
on page 2-23.
When the system is on,
this warning light will come
on to let you know if
there's a problem.
See. When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
To limit wheel spin, especially in slippery road conditions,
you should always leave the traction control system on.
But you can turn the system off if you ever need to. You
should turn the system off if your vehicle ever gets stuck
in sand, mud or snow and rocking the vehicle is required.

If You
Are Stuck: In Sand, Mud, Ice or Snow on page 4-30. United States
