3-5

Turn and Lane-Change Signals
The turn signal has two upward positions for right and
two downward positions for left. These positions
allow you to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn is ®nished, the lever will return
automatically.
An arrow on the instrument
panel cluster will ¯ash in
the direction of the
turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to ¯ash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.If the arrow ¯ashes faster than normal 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.
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 for burned-out bulbs and then check the
fuse. See
Fuses and Circuit Breakers on page 5-89.
A chime will sound if you leave your turn signal on for
more than 3/4 mile (1.2 km).
Headlamp High/Low-Beam Changer
To change your headlamps from low beams to
high beams, or high to low, pull the multifunction lever
all the way toward you. Then release it.
This light, located on the
instrument panel cluster,
will come on while the
high-beam lamps are on.
3-6

Flash-to-Pass
This feature lets you use your high-beam headlamps to
signal the driver in front of you that you want to pass.
It works even if your headlamps are off.
To use it, pull the turn signal lever toward you a little,
but not so far that you hear a click.
If your headlamps are off or on low beam, your
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 dash will come on. Release
the lever to return to normal operation.
Windshield Wipers
To operate the windshield wipers turn the band located
on the multifunction lever upward or downward.
WIPER:Turn this band to control the windshield wipers.
OFF:Turn the band to OFF to turn off the windshield
wipers.
LO (Low Speed):Turn the band away from you to LO
and past the delay settings for steady wiping at low
speed.HI (High Speed):Turn the band away from you, to HI,
and past the delay settings for wiping steady at high
speed.
(Delayed Wiping):Turn the band away from you, just
past OFF, to one of the ®ve sensitivity settings, to
choose the delayed wiping cycle. The further the band
is turned upward, toward LO, the shorter the delay
will be. Use this setting for light rain or snow.
MIST:Turn the band to MIST for a single wiping cycle.
Hold it until the windshield wipers start. Then let it
go. The windshield wipers will stop after one wipe. If
you want more wipes, hold the band on MIST longer.
Be sure to clear ice and snow from the windshield wiper
blades before using them. If they are frozen to the
windshield, carefully loosen or thaw them. If your blades
do become worn or damaged, get new blades or
blade inserts.
Heavy snow or ice can overload your wipers. A circuit
breaker will stop them until the motor cools. Clear away
snow or ice to prevent an overload.

Daytime Running Lamps/Automatic
Headlamp System
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 makes the
DRL work, so be sure it isn't covered.
The DRL system will make your front turn signal lamps
come on when the following conditions are met:
·The ignition is on,
·the exterior lamps control is off and
·the parking brake is released.
While the DRL are on, only your front turn signal lamps
will be on. The headlamps, taillamps, sidemarker
and other lamps won't be on. Your instrument panel
won't be lit up either.When it's dark enough outside, your front turn signal
lamps will turn off and your vehicle's headlamps
and parking lamps will turn on. The other lamps that
come on with your headlamps will also come on.
When it's bright enough outside, your headlamps will
go off and your front turn signal lamps will come on.
To idle your vehicle with the DRL and automatic
headlamp control off, set the parking brake while the
ignition is in OFF or LOCK. Then start your vehicle. The
DRL, headlamps and parking lamps will stay off until
you release the parking brake.
To turn off the automatic headlamp feature when it's
dark outside, move the exterior lamps control to
the parking lamp position. Your parking lamps will
remain illuminated and your headlamps will turn off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
3-12

Delayed Headlamps
Delayed headlamp illumination provides a period of
exterior lighting as you leave your vehicle's area. The
feature is activated when your vehicle's headlamps
are on due to the automatic headlamp control feature
described previously in this section, and when your
vehicle's ignition is turned off. Your headlamps will then
remain on until the exterior lamps control is moved
from OFF to the parking lamp position or until a
90 second lighting period has ended.
If you turn off the ignition with the exterior lamps control
in the parking lamp or headlamp position, the delayed
headlamp illumination cycle will not occur.
You can customize the vehicle to activate delayed
headlamp illumination when your vehicle's ignition is
turned off under the conditions described above, or you
may choose not to activate this feature under any
conditions.
You can turn the feature on and off when you perform
the following sequence:
1. Turn the ignition key to RUN.
2. Close all the doors.3. Press and hold the power door lock switch. While
holding the door lock switch, cycle the exterior
lamps control on and then off two times.
4. Release the power door lock switch. These steps
must be carried out in a time period of less than
10 seconds, followed by a delay period of no more
than 10 seconds.
5. Then, press and hold the power door unlock switch.
While holding the door unlock switch, turn the
exterior lamps control on and then off two times.
Release the courtesy door unlock switch. These
operations must be carried out in a time period of
less than 10 seconds.
After releasing the door unlock switch, a single chime
will be heard if the delayed headlamp illumination
function has been disabled; two chimes will be heard if
the feature has been enabled. Disconnecting the
vehicle's battery for up to a year will not change the
programmed operation for this feature.
