Turn and Lane-Change Signals
The turn signal has two upward (for right) and
two downward (for left) positions. 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, 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 you momentarily press and release the
lever, the turn signal will ash three times.
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 will not see your turn signal.If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not 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 5-99.
Turn Signal On Chime
If either one of the turn signals are left on and you have
drove more than 3/4 mile (1.2 km), a chime will sound.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high beam,
push the turn signal/multifunction lever toward the
front of the vehicle.
This light on the instrument
panel cluster comes on if
the high beam lamps
are turned on while the
ignition is on.
To change the headlamps from high beam to low beam,
pull the turn signal lever toward the rear of the vehicle.
3-8

Flash-to-Pass
With the turn signal lever in the low-beam position,
pull the lever toward you momentarily to switch
to high-beam, to signal that you are going to pass.
If the headlamps are on, they will return to low-beam
when the lever is released.
Windshield Wipers
Clear ice and snow from the wiper blades before using
them. If they are frozen to the windshield, gently
loosen or thaw them. Damaged wiper blades may not
clear the windshield well, making it harder to see
and drive safely. If the blades do become damaged,
install new blades or blade inserts. For more information,
seeWindshield Wiper Blade Replacement on page 5-52.
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it cools down.
Clear away snow or ice to prevent an overload.Turn the band with the wiper symbol to control the
windshield wipers.
8(Mist):Turn the band to mist for a single wiping
cycle. Hold it there until the wipers start. Then let go.
The wipers stop after one wipe. Hold the band on mist
longer, for more wipe cycles.
9(Off):To stop the wipers, move the band to off.
6(Delay):Turn the band to adjust the delay time.
The delay between wiping cycles becomes shorter as
the band is moved to the top of the lever. This can
be very useful in light rain or snow.
6(Low Speed):Turn the band away from you to
the rst solid band past the delay settings, for steady
wiping at low speed.
?(High Speed):Turn the band further, to the
second solid band past the delay settings, for
high-speed wiping.

Delayed Headlamps
The delayed headlamps feature provides a period of
exterior lighting as you leave the area around your
vehicle. The feature is activated when the headlamps
are on due to the automatic headlamps control
feature described previously in this section, and when
the ignition is turned off. Your headlamps will then
remain on until the exterior lamps control is moved to
the parking lamps position or until the pre-selected
delayed headlamp lighting period has ended.
If you turn off the ignition with the headlamps switch in
the parking lamps or headlamps position, the delayed
headlamps cycle will not occur.
To disable the delayed headlamps feature or change
the time of delay, seeDIC Vehicle Customization
on page 3-60.
