Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high or high
to low, push the turn signal lever all the way forward.
While the high beams are
on, this light on the
instrument panel cluster
also will be on. To change
the headlamps from
high to low, pull the lever
rearward.
Headlamps on Reminder
If you turn the ignition off and leave the headlamps or
parking lamps on and open a door, you will hear a chime
reminding you to turn off the lamps.
Flash-to-Pass
To use the flash-to-pass feature, momentarily pull the
turn signal lever toward you. The high-beam indicator
will flash to indicate to the other driver that you intend to
pass. If the low-beam headlamps are off and you
have the optional fog lamps on, the fog lamps will flash.
Windshield Wipers
Use this lever located on the right side of the steering
column to operate the windshield wipers.
OFF:Move the lever to OFF to turn off the
windshield wipers.
INT (Intermittent):Move the lever to INT to choose a
delayed wiping cycle. Turn the INT ADJ band down
for a longer delay or up for a shorter delay. The further
the INT ADJ band is turned upward, the shorter the
delay will be and the further the INT ADJ band is turned
downward, the longer the delay will be.
3-8

The wiper speed can only be adjusted when the lever
is in the INT position. Use this position for light rain
or snow.
LO (Low Speed):Move the lever up to the first setting
past INT, for steady wiping at low speed.
HI (High Speed):Move the lever up to the second
setting past INT, for steady wiping at high speed.
MIST:Move the lever all the way down to MIST for a
single wiping cycle. Hold it there until the windshield
wipers start; then let go. The windshield wipers will stop
after one wipe. If you want more wipes, hold the
band on MIST longer.
Heavy snow or ice can overload the wipers. If this
occurs, a circuit breaker will stop the wipers until the
motor cools. So, be sure to clear any ice and snow from
the windshield wiper blades before using them. If the
wiper blades are frozen to the windshield, carefully
loosen them or warm the windshield before turning the
wipers on. If your blades do become worn or
damaged, get new blades or blade inserts.Windshield Washer
The lever on the right side of the steering column also
controls the windshield washer. There is a button at
the end of the lever. To spray washer fluid on the
windshield, press the button and hold it. The washer will
spray until you release the button. The wipers will
continue to clear the window for about six seconds after
the button is released and then stop or return to your
preset speed.
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
If the fluid in the windshield washer fluid reservoir is low,
the message LOW WASHER FLUID will appear on the
Driver Information Center (DIC) display. It will take
60 seconds after the bottle is refilled for this message to
turn off. For information on the correct washer fluid to
use, seeWindshield Washer Fluid on page 5-36and
Recommended Fluids and Lubricants on page 6-11.

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 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 do not use cruise control on steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:
•Step lightly on the brake pedal or push the clutch
pedal, if you have a manual transmission vehicle.
•Move the cruise switch to OFF.
The Driver Information Center (DIC) will display the
message CRUISE DISENGAGED.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
cruise control set speed memory is erased.
Exterior Lamps
The exterior lamp switch on the turn signal/multifunction
lever operates the headlamps.
The exterior lamp switch has three positions:
OFF:Turn the switch to this position to turn off all
lamps, except the Daytime Running Lamps (DRL).
;(Parking Lamps):Turn the switch to this position
to turn on the parking lamps, together with the
following:
•Taillamps
•Parking Lamps
•Sidemarker Lamps
3(Headlamps):Turn the switch to this position to
turn on the headlamps, together with the previously
listed lamps.
3-13

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
first sold in Canada.
The DRL system will make the front turn signal lamps
come on when the following conditions are met:
•The ignition is on,
•the exterior lamp switch is off and
•the parking brake is released.
When the DRL are on, only the front turn signal lamps
will be on. The headlamps, taillamps, sidemarker
and other lamps will not be on. Your instrument panel
will not be lit up either.
To idle the vehicle with the DRL off, set the parking
brake while the ignition is in OFF. Then start the vehicle.
The DRL, headlamps and parking lamps 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.
Fog Lamps
Your vehicle may have this feature. Use the fog lamps
for better vision in foggy or misty conditions. Your
parking lamps or low-beam headlamps must be on or
the fog lamps will not work.
To turn the fog lamps on, press the button located on
the instrument panel, to the left of the steering column. A
light in the button will come on while the fog lamps
are on. Press the button again to turn the fog lamps off.

Twilight Sentinel®(Optional in United
States, Standard in Canada)
Twilight Sentinel®can turn your lamps on and off for
you. A light sensor on top of the instrument panel makes
the Twilight Sentinel
®work, so be sure it is not covered.
You can customize your vehicle to turn Twilight
Sentinel
®on or off, except for vehicles first sold in
Canada. SeeDriver Information Center (DIC) on
page 3-48to turn this feature on or off.
When Twilight Sentinel
®is turned on, you will see the
following happen:
•When it is dark enough outside, the front turn signal
lamps (DRL) will go off, and the headlamps and
parking lamps will come on. The other lamps
that come on with headlamps will also come on.
•When it is bright enough outside, the headlamps
will go off, and the front turn signal lamps (DRL)
will come on, as long as the exterior lamp switch is
in the OFF position.
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
full bright position. See “Instrument Panel Brightness
Control” underInterior Lamps on page 3-17.
With Twilight Sentinel
®turned on, you can idle the
vehicle with the lamps off, even when it is dark outside.
First set the parking brake while the ignition is in
OFF. Then start the vehicle. The lamps will stay off until
you release the parking brake.
Twilight Sentinel
®also provides exterior illumination as
you leave the vehicle. If Twilight Sentinel®has turned
on the lamps when you turn off the ignition, your lamps
will remain on until:
•The exterior lamp switch is moved from OFF to the
parking lamp position, or
•a delay time that you select has elapsed.
SeeDriver Information Center (DIC) on page 3-48to
select the delay time that you want. You can also select
no delay time.
If you turn off the ignition with the exterior lamp switch
in the parking lamp or headlamp position, the Twilight
Sentinel
®delay will not occur. The lamps will turn off as
soon as the switch is turned off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

entering the vehicle. The interior lamps will come on
for about 20 seconds when the key is turned to OFF or

You can turn exit and entry lighting off by quickly turning
the headlamps on and off or by quickly turning the
courtesy lamps on and off.
