Horn
Press on the center area of the steering wheel to sound
the horn.
Tilt Wheel
A tilt wheel allows you to adjust the steering wheel
before you drive. You can also raise it to the highest
level to give your legs more room when you exit
and enter the vehicle.
The lever that allows you to tilt the steering wheel is
located on the left side of the steering column.
To tilt the wheel, hold the
wheel and pull the lever
toward you. Then move
the steering wheel to
a comfortable position and
release the lever to lock
the wheel in place.
Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
Turn and Lane-Change Signals
Headlamp High/Low-Beam Changer

Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high or
high to low, pull the turn signal lever toward you,
then release it.
When the high beams are
on, a light on the instrument
panel cluster will also
be on. If your vehicle is
equipped with HUD, this
light will also appear in
the display area.
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 off.
To use it, pull the turn signal lever toward you, 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 will stay on as
long as you hold the lever toward you and the high-beam
indicator on the instrument panel cluster will come on.
Release the lever to turn the high-beam headlamps off.
Windshield Wipers
The windshield wipers are controlled by turning the
band marked WIPER.
OFF:Turn the band to OFF to turn the wipers off.
MIST:For a single wiping cycle, turn the band to MIST.
Hold it there until the wipers start, then let go.
The wipers will stop after one cycle. If you want more
cycles, hold the band on MIST longer.
LO (Low Speed):Turn the band to LO for steady
wiping at a slow speed.
HI (High Speed):Turn the band to HI for steady wiping
at a high speed.
The wiper speed may be set for a long or short delay
between wipes. Turn the band to choose the delay time.
The closer to LO, the shorter the delay.
Heavy snow or ice can overload your wiper motor.
A circuit breaker will stop the motor until it cools.
Clear away snow or ice to prevent an overload.
Keep in mind that damaged wiper blades may prevent
you from seeing well enough to drive safely. To avoid
damage, be sure to clear ice and snow from the
wiper blades before using them. If your blades do
become damaged, get new blades or blade inserts.

Rainsense™ II Wipers
If your vehicle has this feature, the moisture sensor is
mounted on the interior of the windshield below the
rearview mirror and is used to automatically operate
the wipers. This system operates by monitoring
the amount of moisture build-up on the windshield.
Wipes occur as needed to clear the windshield
depending on the driving conditions and the sensitivity
setting. In light rain or snow, fewer wipes will occur.
In heavy rain or snow, wipes will occur more frequently.
The system will operate in the delay, low speed and
high speed modes. If the system is left on for long
periods of time, occasional wipes may occur without
any moisture on the windshield. This is normal and
indicates that the Rainsense™ system is active.
The Rainsense™ system is activated by turning the
wiper control band to one of the ve sensitivity levels
within the delay area. The delay position closest to
OFF/MIST is the lowest sensitivity setting, level
one. This allows more rain or snow to collect on the
windshield between wipes. You can increase the
sensitivity of the system and the frequency of wipes by
turning the wiper control band away from you to thehigher sensitivity levels. The highest sensitivity setting,
level ve, is closest to the LO position. A single wipe
will occur each time you turn the wiper control band to a
higher sensitivity level to indicate that the sensitivity
level has been increased.
The windshield wipers also remain in a “high park”
position (the wipers are stopped on the windshield and
are not in the normal park position), even when the
ignition is turned off.
Notice:If you do not turn off the windshield wipers
when driving through an automatic car wash, you
could damage the wipers. Always turn off the
windshield wipers before entering an automatic
car wash.
The MIST and wash cycles operate as normal and
are not affected by the moisture-sensing function.
The system can be overridden at any time by manually
turning the wiper band to LO or HI speed.
Notice:Do not place stickers or other items on
the exterior glass surface directly in front of
the moisture sensor. Doing this could cause the
moisture sensor to malfunction.

Windshield Washer
At the top of the multifunction lever there is a paddle
with the word PUSH on it. For “programmed” operation,
press and release the paddle. The washer will provide
a measured amount of uid to the windshield and
the wiper will either stop or return to your original wiping
speed. For “demand” operation, press and hold the
paddle for at least two seconds. Release the paddle
when you have enough uid and the wipers will either
stop or return to your original wiping speed.
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
If your vehicle is equipped with a DIC, a WINDSHIELD
WASHER FLUID LOW message will appear on the
instrument panel cluster when the vehicle is low
on washer uid. SeeDIC Warnings and Messages on
page 3-50.
Cruise Control
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. This can really help on long trips.
Cruise control does not work at speeds below about
25 mph (40 km/h).
When you apply your brakes, the cruise control shuts off.
{CAUTION:
Cruise control can be dangerous where
you can not drive safely at a steady speed.
So, do not use your cruise control on
winding roads or in heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
needless wheel spinning, and you could
lose control. Do not use cruise control on
slippery roads.

Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected at least
twice a year for wear or cracking. See “Wiper Blade
Check” underPart B: Owner Checks and Services on
page 6-19for more information.
Replacement blades come in different types and are
removed in different ways. For proper type and length,
seeNormal Maintenance Replacement Parts on
page 5-109.
To replace the wiper blade assembly, do the following:
1. Position the wipers on the windshield in the
“mid” wipe position.
2. Lift the windshield wiper arm away from the
windshield. The windshield wiper does not have a
locking upright position feature.3. Push the tab on the wiper blade assembly and pull
the assembly down enough to release it from the
U-hooked end of the wiper arm. Slide the assembly
away from the arm.
4. Replace the blade.
5. To reinstall the wiper blade assembly, slide it over
the wiper arm to engage the U-hooked end on the
wiper blade assembly. Pull up on the assembly
to lock it into place.
