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

Turn and Lane
-Change Signals

Headlamps

Headlamp High/Low Beam
-Changer

Flash
-To-Pass Feature

Fog Lamps
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.
Arrows on the instrument
panel cluster 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 to its original position
when it's released.
Arrows that flash rapidly when signaling for a turn or
lane change may be caused by a burned
-out signal bulb.
Other driver's won't see the signal.
Replace burned
-out bulbs to help avoid possible
accidents. Check the fuse and for burned
-out bulbs if the
arrow fails to work when signaling a turn. See ªFuses
and Circuit Breakersº in the Index for more information.

Headlamp High/Low-Beam Changer
Push forward on the turn signal/multifunction lever to
change the headlamps from low to high beam. Pull the
lever back and then release it to change from high to
low beam.
This light on the instrument
panel cluster will be on,
indicating high
-beam usage.
Lamps On Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp
position and the driver's door is opened with the
ignition off.
Flash-To-Pass Feature
This feature allows you to use the high-beam headlamps
to signal the driver in front of you that you want to pass.
Pull and hold the turn signal/multifunction lever toward
you to use. When you do, the following will occur:

If the headlamps are either off, in low
-beam or in
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 in high
-beam mode, they will
switch to low beam. To return to high
-beam, push
the lever away from you.

Fog Lamps
Use the fog lamps for better vision in foggy or
misty conditions.
The fog lamp control is located on the turn
signal/multifunction lever to the left of the
steering column.The parking lamps must be on for the fog lamps
to work.
To turn the fog lamps on, turn the band on the lever up
to the fog lamp symbol and release it. The band will
return to its original position.
To turn the fog lamps off, turn the band up to the fog
lamp symbol and release it. The band will return to its
original position, and the fog lamps will turn off. If you
turn on the high
-beam headlamps, the fog lamps will
also turn off. They'll turn back on again when you
switch back to low
-beam headlamps.

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 turn signal lamps come
on when the following conditions are met:

It is still daylight and the ignition is in ON
or START,

the exterior lamp control is in OFF or AUTO with
the headlamps off, and

an automatic transmission is not in PARK (P) or the
parking brake is not set on a manual transmission.
When DRL are on, only your turn signal lamps will be on.
No other exterior lamps will be on when the DRL are
being used. Your instrument panel won't be lit up either.
When the exterior lamp control is in AUTO and it's dark
enough outside, the DRL will turn off and the low
-beam
headlamps will turn on. When it's bright enough
outside, the low
-beam headlamps will go off, and the
DRL will turn back on.If it's dark enough outside and the exterior lamp control
is in OFF, a Headlamps Suggested message will appear
on the Driver's Information Center (DIC) display. This
message informs the driver that turning on the exterior
lamps is recommended even though the DRL are still
illuminated. Turning the exterior lamp control to AUTO
or to the low
-beam headlamp position will turn off the
DRL and cancel the Headlamps Suggested message.
If the parking lamps or the fog lamps were turned on
instead, the DRL will still turn off and the Headlamps
Suggested message will be displayed. You can turn it off
by pressing the OK button if you have the Navigation
audio system or the CLR button if you have the base
audio system.
To operate your vehicle with the DRL off, turn the
exterior lamp control to OFF. Then turn on the fog
lamps or parking lamps, and the DRL will turn off.
The Headlamps Suggested message will appear on the
DIC display. This will work regardless of gear position
and whether or not the parking brake is set.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

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.
