Wiper Activated Headlamps
This feature turns on the low-beam headlamps,
instrument panel cluster backlighting and taillamps when
the Twilight Sentinel
žis 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
žmust 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
žor
the windshield wipers.

Headlamps 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
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.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL and
Twilight Sentinel
ž, 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).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
žlever 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 your vehicle has this feature, 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 Sentinelž
Twilight Sentinelžturns 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.
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
ž
lever all the way to OFF. To turn the exterior lamps back
on, slide the lever toward MAX again, or shift out of
PARK (P).
Park Lamp Override Feature
If the Twilight Sentinelžlighting 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
žfeature to deactivate.
The wiper-activated headlamps will override the twilight
disable feature.
Light Sensor
Your Twilight Sentinelž
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
žlighting 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 against 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 Sentinel
žº underExterior Lamps
on page 3-14.
Interior Lamps
Instrument Panel Brightness
The lever for this feature is
located to the left of the
steering column.
The brightness of the instrument panel lights can be
adjusted by sliding the INTERIOR lever from LO to HI.
The instrument panel lights will be on only while the
parking lamps are on. The interior courtesy lamps can
be turned on by sliding the INTERIOR lever all the
way to HI.

Battery Load Management
The battery load management feature is designed to
monitor the vehicle's 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, fan at high speed, heated
seats (if equipped) and engine cooling fans.
If your vehicle's battery remains in a heavy discharge
condition for a long period of time, the fan, rear
defogger, heated seats and heated mirrors will be
disabled and the DIC will display BATTERY SAVER
ACTIVE. This can happen either under long periods of
idling or low speed driving with high electrical loading,
or in the event of a charging system fault.
Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high in
your ®eld of view, it may take you more time to
see things you need to see when it's dark
outside. Be sure to keep the HUD image dim
and placed low in your ®eld of view.
If your vehicle is equipped with the Head-Up Display
(HUD), you can see some of the driver information that
appears on your instrument panel cluster.
The information may be displayed in English or metric
units and appears as a re¯ection in the windshield.
The HUD consists of the following information:
·Speedometer Reading
·Turn Signal Indicators
·High-Beam Headlamp Indicator
·Check Gages Message

Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to be
impaired Ð by alcohol or drugs, with night vision
problems, or by fatigue.
Here are some tips on night driving.
·Drive defensively.
·Don't drink and drive.
·Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.
·Since you can't see as well, you may need to slow
down and keep more space between you and
other vehicles.
·Slow down, especially on higher speed roads. Your
headlamps can light up only so much road ahead.
·In remote areas, watch for animals.
·If you're tired, pull off the road in a safe place
and rest.
No one can see as well at night as in the daytime. But
as we get older these differences increase. A
50-year-old driver may require at least twice as much
light to see the same thing at night as a 20-year-old.
What you do in the daytime can also affect your
night vision. For example, if you spend the day in bright
sunshine you are wise to wear sunglasses. Your
eyes will have less trouble adjusting to night. But if
you're driving, don't wear sunglasses at night. They may
cut down on glare from headlamps, but they also
make a lot of things invisible.
4-16

You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even several
seconds, for your eyes to readjust to the dark. When
you are faced with severe glare (as from a driver
who doesn't lower the high beams, or a vehicle with
misaimed headlamps), slow down a little. Avoid staring
directly into the approaching headlamps.
Keep your windshield and all the glass on your vehicle
clean Ð inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a ®lm caused by dust. Dirty glass makes
lights dazzle and ¯ash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you are in a turn or curve. Keep
your eyes moving; that way, it's easier to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim, so should your eyes
be examined regularly. Some drivers suffer from
night blindness Ð the inability to see in dim light Ð and
aren't even aware of it.Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a wet
road, you can't stop, accelerate or turn as well
because your tire-to-road traction isn't as good as on
dry roads. And, if your tires don't have much tread left,
you'll get even less traction. It's always wise to go
slower and be cautious if rain starts to fall while you are
driving. The surface may get wet suddenly when your
re¯exes are tuned for driving on dry pavement.

Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get and
it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine
again and repeat this only when you feel really
uncomfortable from the cold. But do it as little as
possible. Preserve the fuel as long as you can. To help
keep warm, you can get out of the vehicle and do
some fairly vigorous exercises every half hour or so until
help comes.If You Are Stuck: In Sand, Mud, Ice
or Snow
In order to free your vehicle when it is stuck, you will
need to spin the wheels, but you don't want to spin your
wheels too fast. The method known as ªrockingº can
help you get out when you're stuck, but you must
use caution.
{CAUTION:
If you let your tires spin at high speed, they
can explode, and you or others could be
injured. And, the transaxle or other parts of the
vehicle can overheat. That could cause an
engine compartment ®re or other damage.
When you're stuck, spin the wheels as little as
possible. Don't spin the wheels above 35 mph
(55 km/h) as shown on the speedometer.
