snow. Turn the band to choose the delay time. The
closer to LO, the shorter the delay between wipes.
Be sure to clear ice and snow from the wiper blades
before using them. If they're frozen to the windshield,
carefully loosen or thaw them. If your blades do become
damaged, get new blades or blade inserts.
Heavy snow or ice can overload your wipers. A circuit
breaker will stop them until the motor cools. Clear away
snow or ice to prevent an overload.
Windshield Washer
At the top of the multifunction lever, there's a paddle with
the word PUSH on it. To spray washer fluid on the
windshield, push the paddle. The wipers will run for
several sweeps and then either stop or return to your preset
speed. See ªWindshield Washer Fluidº in the Index.
CAUTION:
In freezing weather, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
The LOW WASH light on
your instrument panel
cluster will glow when the
fluid level is low.
Cruise Control (If Equipped)
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot

Daytime Running Lamps / Automatic
Headlamp Control
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.
A light sensor on top of the instrument panel makes the
DRL work, so be sure it isn't covered.
The DRL system will make your front turn signal lamps
come on when:

the ignition is on,

the headlamp switch is off and

the parking brake is released.
When the DRL are on, only your front turn signal lamps
will be on. The headlamps, taillamps, sidemarker and
other lamps won't be on. Your instrument panel won't
be lit up either.When it's dark enough outside, your front turn signal
lamps will turn off and your vehicle's headlamps and
parking lamps will turn on. The other lamps that come
on with your headlamps will also come on.
When it's bright enough outside, your headlamps will go
off and your front turn signal lamps will come on.
To idle your vehicle with the DRL off, set the parking
brake while the ignition is in OFF or LOCK. Then start
your 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.
Delayed Headlamp Illumination
Delayed Headlamp Illumination provides a period of
exterior lighting as you leave your vehicle's area. The
feature is activated when your vehicle's headlamps are
on due to the automatic headlamp control feature
described previously in this section, and when your
vehicle's ignition is turned off. Your headlamps will
then remain on until the headlamp switch is moved from
OFF to the parking lamp position or until a 90 second
lighting period has ended.
If you turn off the ignition with the headlamp switch in
the parking lamp or headlamp position, the Delayed
Headlamp Illumination cycle will not occur.

You can customize the vehicle to activate Delayed
Headlamp Illumination when your vehicle's ignition is
turned off under the conditions described above, or you
may choose not to activate this feature under any
conditions. You can turn the feature on and off when
you perform the following sequence with the doors
closed and the ignition key in RUN:
1. Press and hold the power door lock switch. While
holding the door lock switch, cycle the headlamp
switch on and then off two times.
2. Release the power door lock switch. These steps
must be carried out in a time period of less than
10 seconds, followed by a delay period of no more
than 10 seconds.
3. Then, press and hold the power door unlock switch.
While holding the door unlock switch, turn the headlamp
switch on and then off two times. Release the courtesy
door unlock switch. These operations must be carried out
in a time period of less than 10 seconds.
After releasing the door unlock switch, a single chime
will be heard if the Delayed Headlamp Illumination
function has been disabled; two chimes will be heard if
the feature has been enabled. Disconnecting the
vehicle's battery for up to a year will not change the
programmed operation of this feature.Interior Lamps

Illuminated Entry includes a feature called Theater
Dimming. With Theater Dimming, the lamps don't just
turn off at the end of the delay time. Instead, they slowly
dim after the delay time until they go out. The delay
time is canceled if you turn the ignition key to RUN or
START, so the lamps will dim right away.
When the ignition is on, Illuminated Entry is inactive,
which means the courtesy lamps won't come on unless a
door is opened.
Delayed Entry Lighting
Delayed Entry Lighting lights your vehicle's interior for
a period of time after all the doors have been closed.
The ignition must be off for Delayed Entry Lighting to work.
Just after all the doors have been closed, the Delayed Entry
Lighting feature will continue to work until:

the ignition is in RUN, or

the doors are locked or

an illumination period of 25 seconds has elapsed.If during the illumination period a door is opened, the
timed illumination period will be canceled and the
interior lamps will remain on since a door is open.
Delayed Exit Lighting
This feature illuminates your vehicle's interior for a
period of time after the ignition key is removed from
the ignition.
The vehicle's ignition must be off for Delayed Exit
Lighting to work. When the ignition key is removed,
interior illumination will activate and remain on until:

the ignition is in RUN or,

the power door locks are activated or

an illumination period of 25 seconds has elapsed.
If during the illumination period a door is opened, the
timed illumination period will be canceled and the
interior lamps will remain on since a door is open.
