Press the button to make the front and rear turn
signal lamps ash on and off. Press the button
again to turn the ashers off.
When the hazard warning ashers are on, your

at the side of the road about 300 feet (100 m)
behind your vehicle.
Horn
To sound the horn, press the horn symbols
located on the steering wheel.
211

Tilt Wheel
The tilt wheel will allow you to adjust the steering
wheel before you drive. Raise it to the highest
level to give your legs more room when you exit
and enter your vehicle.
The tilt steering wheel lever is located on the
lower left side of the column.
To tilt the wheel, hold the steering wheel and pull
the lever. Then move the steering wheel to a
comfortable position and release the lever to lock
the wheel in place.

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.
To signal a lane change, raise or lower the lever for
less than one second until the arrow starts to ash.
This will cause the turn signals to automatically
ash three times. It will ash six times if tow-haul
mode is active. Holding the turn signal lever for
more than one second will cause the turn signals to
ash until you release the lever. The lever will
return by itself when it is released.An arrow on the
instrument panel cluster
will ash in the
direction of the turn or
lane change.
As you signal a turn or a lane change, if the
arrows ash more quickly than normal, 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 a
blown fuse. SeeFuses and Circuit Breakers on
page 608.
213

Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a
mile (1.2 km), a chime will sound at each ash
of the turn signal and the message TURN SIGNAL
ON will also appear in the Driver Information
Control (DIC). To turn the chime and message off,
move the turn signal lever to the off position.
Headlamp High/Low-Beam Changer
53(Headlamp High/Low Beam Changer):To
change the headlamps from low to high beam, push
the lever toward the instrument panel. To return to
low-beam headlamps, pull the multifunction lever
toward you. Then release it.
When the high beams
are on, this indicator light
on the instrument panel
cluster will also be on.
Flash-to-Pass
This feature lets you use your high-beam
headlamps to signal a driver in front of you that
you want to pass. It works even if your headlamps
are in the automatic position.
To use it, pull the turn signal lever toward you,
then release it.
If your headlamps are in the automatic position or
on low beam, your high-beam headlamps will
turn on. They will stay on as long as you hold the
lever toward you. The high-beam indicator on
the instrument panel cluster will come on. Release
the lever to return to normal operation.

Windshield Wipers
Be sure to 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, see
Windshield Wiper Blade Replacement on
page 549.
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.
The windshield wipers are controlled by turning
the band with the wiper symbol.
8(Mist):Turn the band to mist for a single
wiping cycle. Hold it there until the wipers start.
Then let go. The wipers will 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):The wiper speed can be set for a long
or short delay between wiping cycles. This can
be very useful in light rain or snow. Turn the band
to choose the delay time. The closer to the top
of the lever, the shorter the delay.
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.

Rainsense™ II Wipers
If your vehicle has Rainsense™ II windshield
wipers, the moisture sensor is located next to the
inside rearview mirror and is mounted on the
windshield. When active, these sensors are able
to detect moisture on the windshield and
automatically turn on the wipers.
To turn on the Rainsense™ feature, the wipers
must be set to one of the ve delay settings on the
multifunction lever. Each of the ve settings
adjusts the sensitivity of the rainsensor.
Since different drivers have different setting
preferences, it is recommended that the mid-range
setting (position 3) be used initially. For more
wipes, select the higher settings; for fewer wipes,
select the lower settings located closer to the
off position on the multifunction lever.The rainsensor will automatically control the
frequency of the wipes from the off setting to the
high speed setting according to the weather
conditions. The wipers can be left in a rainsense
mode even when it is not raining.
When Rainsense™ is active, the headlamps will
turn on automatically if the exterior lamp control is
in the AUTO position.
Notice:Going through an automatic car wash
with the wipers on can damage them. Turn
the wipers off when going through an
automatic car wash.
