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 your speed. When going
downhill, you may have to brake or shift to a lower gear
to keep your speed down. Applying the brake or shifting
into a lower gear will take your vehicle out of cruise
control. If you need to apply the brake or shift to a lower
gear due to the grade of the downhill slope, you may not
want to attempt to use your cruise control feature.
Ending Cruise Control
There are two ways to turn off the cruise control:

Step lightly on the brake pedal; or

press the ON/OFF button.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
your cruise control set speed memory is erased.Exterior Lamps
These switches control these systems:

Headlamps

Taillamps

Parking Lamps

License Lamps

Sidemarker Lamps

Instrument Panel Lights
Headlamps
Press the button with the lamp symbol on it to turn on
the headlamps. Press it again to turn them off. When the
headlamps are turned on, the instrument panel lights as
well as the parking lamps will also turn on.
Wiper
-Activated Headlamps
This feature turns on the headlamps and parking lamps
when the Twilight Sentinel
 is in day mode and after
the windshield wipers have been in use for
approximately six seconds.

To operate the wiper-activated headlamps, the Twilight
Sentinel must be on. If the wiper
-activated headlamps
are on and the ignition switch is turned to RUN, the
wiper
-activated headlamps will continue. When you
turn the key to OFF/UNLOCK, the wiper
-activated
headlamps will immediately turn off. The
wiper
-activated headlamps will also turn off if you
turn off the Twilight Sentinel or the windshield wipers.
Parking Lamps
Press the PARK button to turn on the parking lamps.
Press it again to turn them off. (If the parking lamps
were turned on with the PARK button, they must be
turned off with that button).
When the parking lamps are turned on during the day,
the instrument panel cluster lights and backlighting to
buttons will turn on. At night, the brightness of this
lighting can be adjusted by the instrument panel
intensity/brightness control if the ignition key is turned
to RUN. The radio and climate control displays will also
be on. When it becomes dark outside, the instrument
panel intensity/brightness control will operate all
instrument panel lighting.
Lamps On Reminder
If you leave the manual headlamp or parking lamp
switch on, remove the key from the ignition and open
the driver's door, you will hear a continuous warning
chime. The chime will turn off when the lamps are
turned off.
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.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL and
Twilight Sentinel, so be sure it isn't covered.
The DRL system will make your high
-beam headlamps
turn on at reduced brightness in daylight when:

The ignition is on,

the headlamp switch is off and

the transaxle is not in PARK (P).
When the DRL are on, only your high
-beam headlamps
will be on. The parking lamps, taillamps, sidemarker
and other lamps won't be on.

When it is dark enough outside, your low-beam
headlamps will come on. The other lamps that turn on
with your headlamps will also turn on. When it is bright
enough outside, the regular lamps will go off, and your
high
-beam headlamps change to the reduced brightness
of DRL.
To turn off all exterior lighting at night when you are
parked, turn off the headlamps and move the Twilight
Sentinel control all the way toward OFF. The exterior
lamps will turn back on automatically when you move
the transaxle out of PARK (P).
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Cornering Lamps (If Equipped)
The cornering lamps are designed to turn on when
you signal a turn. This will provide more lighting
when cornering.
Twilight Sentinel

Twilight Sentinel turns your
lamps on and off by sensing
how dark it is outside.
To operate it, leave the lamp switch off.
If you move the control all the way to MAX, your
headlamps will remain on for about three minutes after
you turn off your engine. As you move the control toward
OFF, the headlamps will turn off more quickly when you
move your key from RUN. You can change this delay
time from only a few seconds to three minutes.
The exterior lamps can be completely shut off while the
vehicle is in PARK (P) by sliding the Twilight Sentinel
control all the way toward OFF, and release. To turn the
exterior lamps back on, slide the control all the way
toward OFF again, and release; or, shift out of PARK (P).

Park Lamp Override Feature
If the Twilight Sentinel lighting is active, it can be
disabled by turning on the manual parking lamps. The
lighting will be disabled until the ignition is moved from
RUN or until the outside light level becomes daylight.
The outside light level changing to daylight will cause
the Twilight Sentinel feature to deactivate. If it becomes
dark again, the parking lamps will have to be turned on
again. (If the parking lamps are already on, they will
have to be turned off, then back on to disable twilight).
The wiper
-activated headlamps will override the
twilight disable feature.
Light Sensor
Your Twilight Sentinel and
DRL work with the light
sensor located on top of the
instrument panel.
Don't cover it up. If you do, the sensor will read ªdarkº
and the Twilight Sentinel lighting will turn on.
Interior Lamps
Instrument Panel Intensity/
Brightness Control
The brightness of the
instrument panel lights can
be adjusted by moving the
INTERIOR lever between
LO and HI.
The instrument panel lights will be on only when the
parking lamps are on. The interior courtesy lamps can
be turned on by sliding the INTERIOR lever all the way
to the top, to HI.

2-49 Battery Load Management
The battery load management feature is designed to
monitor the vehicle electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at a
higher RPM setting than normal to make sure the battery
charges. High electrical loads may occur when several
of the following are on: headlamps, high beams, rear
window defogger, high blower fan, heated seats
(if equipped) and engine cooling fans.
Exterior Lighting Battery Saver
If the manual lamp control has been left on, the exterior
lamps will turn off approximately 10 minutes after the
ignition is turned OFF/LOCK. This protects draining the
battery in case you have accidentally left the headlamps
or parking lamps on. If you need to leave the lamps on
for more than 10 minutes, use the manual control to turn
the lamps back on. To delay the lamps from turning off,
see ªTwilight Sentinel

º in the index.
Front Reading Lamps
Front seat reading lamps are turned on or off by pressing
one of the lamps buttons.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle's battery
against drainage from the interior lamps, trunk lamp, glove
box lamp, cigarette lighters or garage door opener. When
the ignition is turned off, the power to these features will
automatically turn off after 10 minutes. Power will be
restored for an additional 10 minutes if any door is
opened, the trunk is opened or the courtesy lamp switch is
turned on. To restore power back to the cigarette lighters
the ignition must be turned back to RUN.
