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 enhanced
traction system begins to limit wheel spin, the cruise
control will automatically disengage. (See ªEnhanced
Traction Systemº in the Index.) When road conditions
allow you to safely use it again, you may turn the cruise
control back on.Setting Cruise Control
CAUTION:
If you leave your cruise control switch 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 it.
1. Press the cruise control ON OFF button. The
indicator light on the button will turn on.
2. Get up to the speed you want.
3. Press the CST SET button and release it. The
CRUISE light on the instrument panel will come on.
4. Take your foot off the accelerator pedal.

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, you can
press the cruise control RES ACCL button for about half
a second.
You'll go right back up to your chosen speed and
stay there.
If you press the RES ACCL button longer than
half a second, the vehicle will keep going faster until
you release the button or apply the brake. So unless
you want to go faster, don't hold down the
RES ACCL button.
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.
Push the CST SET button, then release the button
and the accelerator pedal. You'll now cruise at the
higher speed.
Press the RES ACCL button. 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 RES ACCL button for less
than half a second 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 turn on
the cruise control by pushing the CST SET button.
Reducing Speed While Using Cruise Control
There are two ways to reduce your speed while using
cruise control:

Push the CST SET button until you reach the lower
speed you want, then release it.

To slow down in very small amounts, push the CST
SET button for less than half a second. Each time
you do this, you'll go 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 control speed you set earlier.

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 find this to
be too much trouble and don't use cruise control on
steep hills.
Ending Out of Cruise Control
There are four ways to turn off the cruise control:

Step on the brake pedal.

Press the cruise control RES ACCL button and the
CST SET buttons at the same time.

Press the cruise control CANCEL button.

Press the cruise control ON OFF button. The
indicator light on the cruise control button will
turn off.

Lamps On Reminder
If you turn off the ignition and open the driver's
door while leaving the lamps on, you will hear a
warning chime.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.The DRL system will make your high
-beam headlamps
come on at a reduced brightness when:

the ignition is on,

the headlamp switch is in OFF or you have turned on
your parking lamps,

the light sensor detects daytime light,

the parking brake is released and

the shift lever is not in PARK (P).
When the DRL system is on, the taillamps, sidemarker
lamps, park lamps and instrument panel lights will not
be illuminated.
The DRL system will remain off any time your vehicle
is in PARK (P) or the parking brake is engaged and the
vehicle speed is less than 3 mph (1.9 km/h).
As with any vehicle, you should turn on the regular
headlamp system when you need it.

2-41 Automatic Light Control (ALC)
When it is dark enough outside, your Automatic Light
Control (ALC) will turn on your headlamps along with
other lamps such as the taillamps, sidemarker lamps,
park lamps and the instrument panel lights. The radio
lights will also be dim.
Your vehicle is equipped with a light sensor on the top
of the instrument panel under the defroster grill, so be
sure it is not covered. This will cause the ALC system to
be on whenever the ignition is on.
The ALC system may also come on when driving
through a parking garage, heavy overcast weather or a
tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the DRL and the ALC
systems so that driving under bridges or bright overhead
street lights does not affect the system. The DRL and
ALC systems will only be affected when the light sensor
sees a change in lighting lasting longer than this delay.
To idle your vehicle with the ALC system off, set the
parking brake while the ignition is off. Then start the
vehicle. The ALC system will stay off until you release
the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Delayed Headlamps
The delayed headlamps feature will continue to
illuminate the headlamps for 20 seconds after the key is
turned to OFF.
To turn off the delayed headlamps feature, turn the turn
signal/multifunction lever up one position and then back
to OFF.
Fog Lamps (If Equipped)
The button for your fog lamps is located on the
instrument panel, to the left of the steering wheel, beside
the instrument panel intensity control.
When using the fog lamps, the ignition must be on as
well as the parking lamps or the low
-beam headlamps.
Push the button to turn the fog lamps on. An indicator
light on the button will glow when the fog lamps are on.
Push the button again to turn the fog lamps off.
The fog lamps will turn off whenever the high
-beam
headlamps are turned on. When the high beams are
turned off, the fog lamps will come on again.

Interior Lamps
Instrument Panel Intensity Control
You can brighten or dim the
instrument panel cluster
lights by moving the
thumbwheel up to increase
intensity and to down to
decrease intensity. The
thumbwheel is located on
the instrument panel to the
left of the steering wheel.
Courtesy Lamp Control
When the thumbwheel for the instrument panel intensity
control is moved up, the dome lamp, the mirror reading
lamps (if equipped) and the footwell lamps will turn on.
Move the thumbwheel down to turn the lamps off.
Illuminated Entry/Exit System
When you lift the driver's door handle or open the
driver's door, the lamps inside your vehicle will go on.
These lamps will fade out after about 10 seconds, or
when the ignition is turned on after all doors have been
closed. These lamps will also go on when you press the
trunk release or UNLOCK button on the remote lock
control transmitter (if equipped).
The lamps inside your vehicle will stay on for about
10 seconds after your key is removed from the ignition
to provide an illuminated exit.

2-43 Mirror Reading Lamps (If Equipped)
Press the switch on the lower front portion of the mirror
to turn on the lamps. Press the other side of the switch to
turn the lamps off.
Three-Position Dome Lamp
The switch on this lamp has three positions. The ON
position will turn on the light. The DOOR position will
turn on the light whenever a door is opened or when the
instrument panel intensity control thumbwheel is moved
up. The OFF position will shut off the lamp completely,
even when a door is opened.
Trunk Lamp
The trunk lamp comes on when you open your trunk.
Battery Saver
Your vehicle is equipped with a battery saver feature
designed to protect your vehicle's battery.
When any interior lamp (trunk, mirror reading lamps,
footwell, dome lamp or glove box) is left on when the
ignition is turned off, the battery saver system will
automatically shut the lamp off after 20 minutes.
This will avoid draining the battery.
To reactivate the interior lamps, do one of the following:

Lift the driver's door handle.

Open any door.

Press any remote lock control transmitter button
(if equipped).

Press the power door lock switch.

Press the remote trunk release.

Mirrors
Inside Day/Night Rearview Mirror
This mirror can be adjusted two ways. First, to adjust
the angle of the mirror, move the mirror to a position
that allows you see to out the back window. To adjust
the height of the mirror, adjust the arm that connects the
