Reducing Speed While Using Cruise
Control

Press in the button at the end of the lever until you
reach the lower speed you want, then release it.
To slow down in very small amounts, briey press
the set button. 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 four ways to turn off the cruise control:
Step lightly on the brake pedal,
move the cruise control switch to off, or
shift the transmission to NEUTRAL (N).
If road conditions cause the traction control system
to activate, cruise control will turn off.
If the accelerator pedal is held for 60 seconds or
longer, cruise control will turn off.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.

Automatic Headlamp System
When it is dark enough outside and the headlamp
switch is in AUTO, your automatic headlamp system will
turn on your headlamps at the normal brightness
along with other lamps such as the taillamps,
sidemarker, parking lamps, roof marker lamps and the
instrument panel lights. The radio lights will also be dim.
To turn off the automatic headlamp system, turn the
exterior lamps switch to the off position and then
release.
Your vehicle has a light sensor located 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 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. 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 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. See “Instrument
Panel Brightness” underInterior Lamps on page 3-16.
Lamps On Reminder
If a door is open, a reminder chime will sound when
your headlamps or parking lamps are manually turned
on and your key is out of the ignition. To turn off
the chime, turn the headlamp switch to off or AUTO and
then back on. In the automatic mode, the headlamps
turn off once the ignition is in LOCK and the headlamps
on at exit delay ends (if enabled in the DIC).

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. Fully functional
daytime running lamps 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 transmission is not in PARK (P), and
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 won’t be
on. The instrument panel won’t be lit up either.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Off-Road Lamps
Notice:If you drive your vehicle through an
automatic car wash that does not have enough
clearance for any roof-mounted accessories (such
as off-road lamps or a roof basket) on your vehicle,
you can damage your vehicle. To avoid damaging
your vehicle in a car wash, remove any
roof-mounted accessories if you can, and do not
use an automatic car wash while roof-mounted
accessories are on your vehicle. SeeCleaning the
Outside of Your Vehicle on page 5-95for more
information.
The off-road lamps, if equipped, are designed to
enhance the appearance of your vehicle and to provide
auxiliary lighting when your vehicle is used off road.
The safety characteristics of these lamps are limited and
they are not intended to be used in conjunction with,
or in place of, existing vehicle lighting. The lamps are not
to be used on any public street or highway and are to
be covered when not in use. Check your state and local
laws before installing or using any auxiliary lighting.
In some states it may be necessary to remove the roof
lamps when operating the vehicle on the highway.
The button for the off-road lamps is located in the
overhead console.To use the lamps, be sure the engine is running.
Remove the covers form the lamps and press the button
to turn them on. Press the button again to turn them
off. An indicator light will glow near the button when the
lamps are on.
Notice:Turning on the off-road lamps before
removing the lamp covers could damage the
off-road lamps and the covers. Always remove the
covers before turning on the off-road lamps.
The off-road lamps will remain on even after the ignition
is turned off. The off-road lamps button must be
pressed to turn them off.
Interior Lamps
Instrument Panel Brightness
The thumbwheel for this feature is located next to the

D(Instrument Panel Lights):Turn the thumbwheel
up or down to brighten or dim the instrument panel lights
and the radio display. This will only work if the
headlamps or parking lamps are on.
