Turn and Lane-Change Signals
The turn signal has the following positions: two upward
(for right) and two downward (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 isfinished, the lever will return
automatically.
An arrow on the instrument
panel cluster willflash in
the direction of the
turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts toflash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
If the arrowflashes 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. SeeFuses and Circuit Breakers on page 5-87.
A chime will sound if you leave your turn signal on for
more than 3/4 mile (1.2 km).

high beams, or high to low, pull the multifunction lever
all the way toward you. Then release it.

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 thefive 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
first 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.
When 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’tbe
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.
