2-39
Turn Signal/Multifunction Lever
The lever located 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
For information on the exterior lamps, see ªExterior
Lampsº later in this section.
Turn 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 located 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 is 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.

2-40 Headlamp High/Low-Beam Changer
When the low-beam headlamps are on, push the turn
signal lever away from you to change the headlamps
to high beam.
This light on the
instrument panel cluster
will be on, indicating
high
-beam usage.
Pull the turn signal lever toward you to return to
low
-beam headlamps.
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 the turn signal lever toward you briefly to
flash
-to-pass. 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 low beam, they will remain
active and the high beam will also illuminate until
you release the lever.

2-48 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 first sold in Canada.
The DRL system will make the high
-beam headlamps
come on at reduced brightness when the following
conditions are met:

It is still daylight and the ignition is on,

the exterior lamp control is in the off position and

the transaxle is not in PARK (P).
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.

2-49 Fog Lamps (STS Only)
Use the fog lamps for better vision in foggy or
misty conditions.
When the ignition is on and you push the fog lamp
button located next to the exterior lamps control,
a small indicator light in the fog lamp button, the
LIGHTS ON and fog lamp indicator lights on the
instrument panel cluster will come on to indicate that
the fog and the parking lamps are on.
Press the fog lamp button again to turn off the
fog lamps.
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.
Twilight Sentinel

This lever is located below
the exterior lamps control.
It automatically turns the
lamps on and off by sensing
how dark it is outside.
To operate the Twilight Sentinel, leave the exterior
lamps control off and slide the TWILIGHT lever to
any position but OFF.
If you move the lever all the way to the right, the lamps
will remain on for approximately three minutes after the
ignition has been turned to OFF. If you move the lever
so it is barely on, the lamps will go off quickly when
you turn the ignition switch out of OFF. You can
adjust the delay time from only a few seconds to
about three minutes.
If it's dark enough outside and the Twilight Sentinel
lever is off, a HEADLAMPS SUGGESTED message
will display on the Driver Information Center (DIC).

2-52 Illuminated Entry
The illuminated entry system turns on the courtesy
lamps and the backlighting to the door switches and to
the exterior lamp control when a door is opened or if
you press the remote keyless entry transmitter unlock
button. If activated due to the transmitter, the lighting
will remain active for about 40 seconds. Since the
illuminated entry system uses the light sensor, it must be
dark outside in order for the courtesy lamps to turn on.
The courtesy lamps turn off approximately 25 seconds
after the last door is closed. They will dim to off if the
ignition key is placed in ON, or immediately deactivate
if the power locks are activated.
Parade Dimming
This feature prohibits dimming of the digital displays
and backlighting during daylight hours when the key is
in the ignition and the headlamps are on. This feature
operates with the light sensor for the Twilight Sentinel
and is fully automatic. When the light sensor reads
darkness outside and the parking lamps are active,
the digital displays can be adjusted by turning the
instrument panel brightness knob counterclockwise
to dim and clockwise to brighten lighting.
Reading Lamps
The front reading lamps are located in the overhead
console. These lamps and the interior courtesy lamps
come on when a door is opened and it is dark outside.
The rear reading lamps will not come on when a front
door is opened.
The rear courtesy lamps are located on the rear headliner
above the rear seat outboard positions. When a rear door
is opened, both the front and rear reading lamps come
on with the courtesy lamps.
Press the button near each lamp to turn it on and off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
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.

Here are some tips on night driving.

Drive defensively.

Don't drink and drive.

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.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.
