Cruise Control
{CAUTION:
Cruise control can be dangerous where
you cannot drive safely at a steady speed.
So, do not 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
excessive wheel slip, and you could lose
control. Do not use cruise control on
slippery roads.
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, cruise control
is turned off.If your vehicle has the StabiliTrak
®™ system and
begins to limit wheel spin while you are using
cruise control, the cruise control will automatically
disengage. SeeStabiliTrak
®System on
page 348. When road conditions allow you to
safely use it again, you may turn the cruise control
back on.
The cruise control
buttons are located on
left side of the
steering wheel.
T(On/Off):This button can both activate and
turn off the system. The indicator light is on
when cruise control is on and turns off when cruise
control is off.
196

+ RES (Resume/Accelerate):Press this button
to make the vehicle accelerate or resume to
a previously set speed.
SET−(Set):Press this button to set the speed or
make the vehicle decelerate.
[(Cancel):Press this button to cancel cruise
control without erasing the set speed from
memory.
Setting Cruise Control
Cruise control will not work if your parking brake is
set, or if the master cylinder brake uid level is low.
The cruise control light on the instrument panel
cluster will come on after the cruise control
has been set to the desired speed.
{CAUTION:
If you leave your cruise control on when
you are not using cruise, you might hit a
button and go into cruise when you do
not want to. You could be startled and
even lose control. Keep the cruise control
switch off until you want to use cruise
control.
1. Press the cruise control On/Off button.
2. Get up to the desired speed you want.
3. Press the SET−button located on the steering
wheel and release it.
4. Take your foot off the accelerator.

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
the vehicle’s speed. When going downhill, you may
have to brake or shift to a lower gear to keep the
vehicle’s speed down. Of course, applying the
brake takes you out of cruise control. Many drivers
nd this to be too much trouble and do not use
cruise control on steep hills.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the cancel button on the steering wheel.
Press the On/Off button on the steering wheel.
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
The exterior lamps control has four positions:
9(Off):Turn the control to this position
and release to turn off the automatic headlamps
and daytime running lamps (DRL). Turning
the headlamp control to the off position again will

Daytime Running Lamps (DRL)
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. Fully functional DRL are required on all
vehicles rst sold in Canada.
The DRL system will come on when the following
conditions are met:
The ignition is on
The exterior lamps control is in AUTO
The light sensor determines it is daytime
When the DRL are on, only your DRL lamps will
be on. The taillamps, sidemarker and other
lamps will not be on. The instrument panel back
lighting will not be on either.
When it begins to get dark, the automatic
headlamp system will switch from DRL to the
headlamps.
When you turn the headlamp switch off, the
headlamps will go off, and your DRL lamps will
illuminate, provided it is not dark outside.
Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on the headlamps at the
normal brightness, along with the taillamps,
sidemarker, parking lamps, and the instrument
panel lights. The radio back lighting will also
be dimly lit.
To turn off the automatic headlamp system, turn
the exterior lamps switch to the off position.
Turning off the automatic headlamp system with
the headlamp switch is not available for vehicles
rst sold in Canada.
Your vehicle has a light sensor located on the
top of the instrument panel in the defroster grille
that regulates when the automatic headlamps turn
on. Be sure it is not covered, or the system will
come on whenever the ignition is on.
The system may also turn on your headlamps
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 Daytime
Running Lamps (DRL) and the automatic headlamp
systems so that driving under bridges or bright
overhead street lights does not affect the system.
201

The DRL and automatic headlamp system will only
be affected when the light sensor sees a change in
lighting lasting longer than the delay.
If you start your vehicle in a dark garage, the
automatic headlamp system will come on
immediately. Once you leave the garage, it will
take approximately one minute for the automatic
headlamp system to change to DRL if it is
bright enough outside. During that delay, your
instrument panel cluster may not be as bright as
usual. Make sure your instrument panel brightness
control is in the full bright position. SeeInstrument
Panel Brightness on page 203.
To idle your vehicle with the automatic headlamp
system off, turn the control to the off position.
You may be able to turn off your Automatic
Headlamp System. SeeDaytime Running Lamps
(DRL) on page 201for more information.
Your headlamps will also stay on after you exit the
vehicle. You can program this feature using the
Driver Information Center (DIC). SeeDIC Vehicle
Customization (With DIC Buttons) on page 264.
As with any vehicle, you should turn on the regular
headlamp system when needed.Fog Lamps
-(Fog Lamps):If your vehicle is equipped with
fog lamps, it is located on the instrument panel to
the left of the steering column. The fog lamps
button is located below the dome lamp override
button.
Your ignition must be in RUN for the fog lamps to
illuminate.
To turn the fog lamps on, press the fog lamps
button. A light will come on in the instrument panel
cluster to let you know that the fog lamps are on.
Press the button again to turn the fog lamps off.
The ignition must be in RUN and the parking
lamps must be on for your fog lamps to work.
The fog lamps will go off while you change
to high-beam headlamps.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
