Setting Cruise Control
1. Move the cruise control switch to on.
2. Get up to the speed you want.
3. Press the set button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.
The accelerator pedal will not go down.
The cruise light on the
instrument panel cluster will
come on when the cruise
control is engaged.
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 move the cruise control switch briey from
on to resume/accelerate.
You’ll go right back up to your chosen speed
and stay there.
If you hold the switch at resume/accelerate, the vehicle
will keep going faster until you release the switch or
apply the brake. So unless you want to go faster, don’t
hold the switch at resume/accelerate.
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 button at the end of the lever, then
release the button and the accelerator pedal.
You’ll now cruise at the higher speed.
Move the cruise switch from on to resume/
accelerate. Hold it there until you get up to the speed
you want, and then release the switch. To increase
your speed in very small amounts, move the switch
briey to resume/accelerate. Each time you do this,
your vehicle will go about 1 mph (1.6 km/h) faster.

Reducing Speed While Using Cruise
Control
Press in the set button at the end of the lever until you
reach the lower speed you want, then release it. 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 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 want 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 turn off the cruise control:
Step lightly on the brake pedal.
Move the cruise switch to off, or
Shift the transmission to NEUTRAL (N).
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.

Headlamps on Reminder
A reminder tone will sound when your headlamps or
parking lamps are manually turned on, the driver’s door
is open and your ignition is in LOCK or ACCESSORY.
To turn the tone off, turn the knob all the way
counterclockwise. In the automatic mode, the headlamps
turn off once the ignition key is in LOCK.
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
daytime running lamps are required on all vehicles
rst sold in Canada.
The DRL system will make your headlamps come
on at reduced brightness when the following conditions
are met:
The ignition is on.
The exterior lamps knob is in automatic
headlamp mode.
The light sensor detects daytime light.
The transmission is not in PARK (P).
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won’t be
on. The instrument panel won’t be lit up either.
When it begins to get dark, the headlamps will
automatically switch from DRL to the regular headlamps.
Automatic Headlamp System
When it is dark enough outside, your Automatic
Headlamp System will turn on your headlamps at the
normal brightness along with other lamps such as
the taillamps, sidemarker, parking lamps and the
instrument panel lights. The radio lights will also be on.
Your vehicle is equipped with a light sensor on the
top of the instrument panel. Be sure it is not covered or
the system will be on whenever the ignition is on.
The system may also turn on your lights when driving
through a parking garage, heavy overcast weather
or a tunnel. This is normal.
3-16

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. 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 about one minute for
the automatic headlamp system to change to DRL if it is
light 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.
To idle your vehicle with the automatic headlamp system
off, set the parking brake while the ignition is off. Then
start your vehicle. The automatic headlamp system will
stay off until you release the parking brake, shift out of
park or turn the exterior lamp control to the off position as
described in “Exterior Lamps” listed previously.Fog Lamps
Your vehicle may have this feature. Use your fog lamps
for better vision in foggy or misty conditions. Your
ignition must be in RUN for your fog lamps to work.
The fog lamp button is
located on the instrument
panel to the right of
the exterior lamps knob.
Press the button to turn the fog lamps on. Press the
button again to turn them off. A light will glow near the
button while the fog lamps are on. Fog lamps will
turn off whenever your high-beam headlamps are on.

lamps, it may be necessary to do one of the following to
return to normal operation:
Shut off all lamps and close all doors.
Turn the ignition key to RUN.
This feature will also turn off the parking lamps and
headlamps under most circumstances, if they are left on.
If you would like to turn them back on, turn the exterior
lamps knob.
