Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:

Turn and Lane
-Change Signals

Headlamp High/Low
-Beam Changer

Flash
-To-Pass Feature

Windshield Wipers

Windshield Washer
For more information on the exterior lamps, see
ªExterior Lampsº later in this section.
Turn and Lane-Change Signals
To signal a turn, move the lever 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
lane change.
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 returns when it's released.
If the turn signal is left on, a warning chime will sound
and the Driver Information Center (DIC) will display
TURN SIGNAL ON after driving about a mile to
remind you to turn it off.
Arrows that flash rapidly when signaling for a turn or
lane change may be caused by a burned out signal bulb.
Other drivers won't see the turn signal.
Replace burned
-out bulbs to help avoid possible
accidents. Check the fuse (see ªFuses and Circuit
Breakersº in the Index) and for burned
-out bulbs if the
arrow fails to work when signaling a turn.

Headlamp High/Low-Beam Changer
Push forward to change the headlamps from low beam
to high. Pull the lever back and then release it to change
from high beam to low.
This light on the instrument
panel cluster will be on,
indicating high
-beam usage.
Flash-To-Pass
This feature lets you use the high-beam headlamps to
signal the driver in front of you that you want to pass.
Pull and hold the turn signal lever toward you to use.
When you do, the following will occur:

If the headlamps are either off or in the Daytime
Running Lamps (DRL) mode, the high
-beam
headlamps will turn on. They'll stay on as long as
you hold the lever there. Release the lever to turn
them off.

If the headlamps are on high beam, they will switch
to low beam. To return to high beam, push the lever
away from you.
Windshield Wipers
WIPER: Turn the band on the turn signal lever to
control the wipers.
MIST: Turn the band toward you to MIST and then
release it for a single wiping cycle. For more cycles,
hold the band on MIST longer.
LO or HI: Turn the band away from you to either
LO (low speed) or to HI (high speed), depending on
the wiper speed you want.
DELAY: Turn the band to one of the DELAY positions
to set the wiper speed for a long or a short delay
between wipes. The closer you move it to LO, the
shorter the delay.
OFF: Turn the band to OFF to turn off the wipers.

2-52
When DRL are on, only your high-beam headlamps
(at reduced brightness) will be on. No other exterior
lamps such as the parking lamps, taillamps, etc. will be
on when the DRL are being used. Your instrument panel
won't be lit up either.
When the Twilight Sentinel

lever is on and it's dark
enough outside, the high
-beam headlamps (at reduced
intensity) will turn off and normal low
-beam headlamp
operation will occur. When the Twilight Sentinel lever is
on and it's bright enough outside, the regular lamps
will go off, and the high
-beam headlamps at reduced
brightness will take over.
If it's dark enough outside and the Twilight Sentinel
lever is off, a HEADLAMPS SUGGESTED message
will display on the Driver's Information Center (DIC).
This message informs the driver that turning on the
exterior lamps is recommended even though the
DRL are still illuminated.Turning on the Twilight Sentinel or the headlamps will
deactivate the DRL and remove the HEADLAMPS
SUGGESTED message. If the parking lamps or the
fog lamps were turned on instead, the DRL will still
deactivate and the HEADLAMPS SUGGESTED
message will continue to be displayed.
To idle your vehicle with the DRL off at night, turn
off the Twilight Sentinel and shift the transaxle into
PARK (P). Placing your vehicle in PARK (P) disables
the DRL. The DRL will stay off until you shift out
of PARK (P).
To drive your vehicle with the DRL off, turn off the
Twilight Sentinel and manually turn on the parking
lamps or fog lamps (if equipped).
As with any vehicle, you should turn on the regular
headlamp system when you need it.

2-53
Fog Lamps (If Equipped)
Use the fog lamps for better vision in foggy or
misty conditions.
The fog lamp button is
located to the left of the
steering wheel on the
instrument panel.
When you press the fog lamp button, a fog lamp symbol
in the button and the fog lamp light on the instrument
panel cluster will come on to indicate that the fog lamps
and the parking lamps are on.Press the button again to turn them off.
If you turn on the high
-beam headlamps, the fog
lamps will turn off. They'll turn back on again when
you switch to low
-beam headlamps.
When the Twilight Sentinel

is on and the fog lamps are
turned on, the fog lamps, headlamps and parking lamps
will remain on.
The ignition must be on for the fog lamps to operate.
Cornering Lamps
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.

2-58
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 revolutions per minute (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, fog lamps, rear window
defogger, the climate control fan at high speeds,
heated seats and engine cooling fans.
If the battery continues to discharge, even with the
engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer to
clear the glass, the heated seats may not get as warm as
they usually do and the fan may cut back to a lower
speed. For more battery saving information, see ªBattery
Saver Active Messageº in the Index.
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 the garage
door opener. When the ignition is turned off, the
power to these features will automatically turn off after
10 minutes (three minutes if a new car has 15 miles
(24 km) or less). 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.

4-18
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
-- 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 film caused by dust. Dirty glass makes
lights dazzle and flash 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
-- the inability to see in dim light -- 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 reflexes are
tuned for driving on dry pavement.

Headlamp Aiming
Your vehicle has a visual optical headlamp aiming system
equipped with horizontal aim indicators. The aim has been
preset at the factory and should need no further adjustment.
This is true even though your horizontal aim indicators may
not fall exactly on the ª0º (zero) marks on their scales.If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the low beam
may be necessary if it is difficult to see lane markers
(for horizontal aim), or if oncoming drivers flash their
high beams at you (for vertical aim). If you believe your
headlamps need to be re
-aimed, we recommend that you
take your vehicle to your dealer for service. However, it
is possible for you to re
-aim your headlamps as
described in the following procedure.
NOTICE:
To make sure your headlamps are aimed
properly, read all the instructions before
beginning. Failure to follow these instructions
could cause damage to headlamp parts.

6-41
The vehicle should be properly prepared as follows:

The vehicle should be placed so the headlamps
are 25 ft. (7.6 m) from a light colored wall or other
flat surface.

The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall or
other flat surface.

The vehicle should be placed so it is perpendicular to
the wall or other flat surface.

The vehicle should not have any snow, ice or mud
attached to it.

The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.

The vehicle should be normally loaded with a full
tank of fuel and one person or 160 lbs. (75 kg) on the
driver's seat.

Tires should be properly inflated.
Headlamp aiming is done with the vehicle low beam
lamps. The high beam lamps will be correctly aimed if
the low beam lamps are aimed properly.
The headlamp aiming devices are under the hood near
the headlamps.
If you believe your headlamps need horizontal
(left/right) adjustment, follow the horizontal aiming
procedure. If you believe your headlamps need only
vertical (up/down) adjustment, follow only the vertical
aiming procedure.
Adjustment screws can be turned with an E8 Torx

socket or T15 Torx screwdriver.
