NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you don't,
your engine might not perform properly.
Engine Coolant Heater (If Equipped)
In very cold weather, 0
F (-18
C) or colder, the engine
coolant heater can help. You'll get easier starting and
better fuel economy during engine warm
-up. Usually, the
coolant heater should be plugged in a minimum of four
hours prior to starting your vehicle. At temperatures above
32
F (0
C), use of the coolant heater is not required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The engine coolant heater cord is located on
the passenger's side of the vehicle, above the
headlamp assembly.3. Plug it into a normal, grounded 110
-volt AC outlet.
CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three
-prong
11 0
-volt AC outlet. If the cord won't reach,
use a heavy
-duty three-prong extension cord
rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you don't, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for
that particular area.

The lever on the left side of the steering column
includes the following:

Turn Signal and Lane Change Signals

Headlamp High/Low
-Beam Changer

Flash
-To-Pass Feature

Windshield Wipers

Windshield Washer
For more information on exterior lamps, see ªExterior

Turn Signal and Lane Change Signals
To signal a turn, move the lever on the left side of the
steering wheel all the way up or down. The lever returns
automatically when the turn is complete.
An arrow on the instrument
panel cluster will flash in
the direction of the turn or

-Up Display (HUD)º in the Index for
more information.
Raise or lower the lever until the arrow starts to flash to
signal a lane change. Hold it there until the lane change
is complete. The lever will return by itself when you
release it.
If the arrows flash very fast as you signal a turn or a
lane change, a signal bulb may be burned out and other
drivers won't see your turn signal.

2-37
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you
signal a turn, check the fuse (see ªFuses and Circuit
Breakersº in the Index) and for burned
-out bulbs.
Turn Signal On Chime
If your turn signal is left on for more than 0.8 miles
(1.3 km), a chime will sound at each flash of the turn
signal. To turn off the chime, move the turn signal lever
to the off position.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high beam
or high beam to low beam, pull the turn signal lever
toward you and release it.
When the high beams are
on, this light located on the
instrument panel cluster will
also be on.If your vehicle is equipped with the Head
-Up Display
(HUD), an arrow will also appear in the display area to
indicate the high beams are on (See ªHead
-Up Display
(HUD)º in Index for more information).
Flash-To-Pass Feature
This feature lets you use the high-beam headlamps to
signal the driver in front of you that you want to pass.
It works even if your headlamps are off.
Pull the turn signal lever toward you briefly to
flash
-to-pass.
If the headlamps are off or on low beam, the high
-beam
headlamps will turn on. They'll stay on as long as you
hold the lever toward you and the high
-beam indicator
on the instrument panel cluster comes on. Release the
lever to turn the high
-beam headlamps off.

2-38 Windshield Wipers
The windshield wipers are controlled by turning the
band marked WIPER.
For a single wiping cycle, turn the band to MIST. Hold
it there until the wipers start, then let go. The wipers will
stop after one cycle. If you want more cycles, hold the
band on MIST longer.For steady wiping at low speed, turn the band away
from you to the LO position. For high
-speed wiping,
turn the band further, to HI. To stop the wipers, turn
the band to OFF.
The wiper speed may be set for a long or short delay
between wipes. Turn the band to choose the delay time.
The closer to LO, the shorter the delay.
Heavy snow or ice can overload your wiper motor.
A circuit breaker will stop the motor until it cools.
Clear away snow or ice to prevent an overload.
Keep in mind that damaged wiper blades may prevent
you from seeing well enough to drive safely. To avoid
damage, be sure to clear ice and snow from the wiper
blades before using them. If your blades do become
damaged, get new blades or blade inserts.
If your windshield wipers are on for more than
six seconds while you are driving, the low
-beam
headlamps, instrument panel cluster backlighting
and taillamps will turn on. For more information
see ªWiper
-Activated Headlampsº in the Index.

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 ON/OFF.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
your cruise control set speed memory is erased.Exterior Lamps
The exterior lamp control
buttons are located to the
left of the steering column.

symbol turns on the parking lamps, together with the
following:

Sidemarker Lamps

Taillamps

License Plate Lamps

Instrument Panel Lights
(Headlamps): Pressing the button with this symbol
turns on the headlamps, together with the previously
listed lamps and lights.

Wiper-Activated Headlamps
This feature turns on the low
-beam headlamps,
instrument panel cluster backlighting and taillamps
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, 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.
Lamps On Reminder
If you leave the exterior lamp buttons for the headlamps
or parking lamps 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 (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 first sold in Canada.
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
following conditions are met:

The ignition is on,

the exterior lamp button for the headlamps is off and

the transaxle is not in PARK (P).

2-45
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 lever 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 come on when the headlamps
or parking lamps are on and you signal a turn with
the multifunction lever. They provide more light
for cornering.
Twilight Sentinel

Twilight Sentinel turns your headlamps on and off by
sensing how dark it is outside.
The lever for this feature is
located to the left of the
steering column.
To operate it, leave the exterior lamp button off.
If you slide the lever all the way to MAX, your
headlamps will remain on for about three minutes after
you turn off your engine. As you slide the lever 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.

2-46
The exterior lamps can be completely shut off while
the vehicle is in PARK (P) by sliding the Twilight
Sentinel lever all the way toward OFF, and releasing it.
To turn the exterior lamps back on, slide the lever all
the way toward OFF again, and release it; 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.
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.
Exterior Lighting Battery Saver
If the exterior lamp button has been left on, the exterior
lamps will turn off approximately 10 minutes after the
ignition is turned to LOCK and any door has been
opened. 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 after the ignition is turned to LOCK and any
door is opened. To delay the lamps from turning off,
see ªTwilight Sentinelº in the index.

2-48 Theater Dimming
This feature allows for a three to five-second fade out of
the courtesy lamps instead of immediate turn off.
Delayed Exit Lighting
If it is dark enough outside when you remove the key
from the ignition, the interior lamps will turn on and
stay on for approximately 25 seconds. This will give
you time to find the door pull handle or lock switches.
Once the key is inserted into the ignition the exit
lighting will be cancelled and the lighting will fade out.
Perimeter Lighting
If it is dark enough outside when the button with the
unlock symbol on the remote keyless entry transmitter is
pressed, the DRL headlamps, parking lamps and
back
-up lamps will come on.Personal Choice Programming
This feature can be programmed in the on or off mode
for each transmitter.
If your vehicle is equipped with the Driver Information
Center (DIC), you must use it to program this feature.
See ªDriver Information Center (DIC)º in the Index.

lighting remains on at this time and the horn will
chirp two times.
4. Press the instant alarm on the transmitter again.
Perimeter lighting is disabled and the horn will chirp
one time.
