driver to enter and exit the vehicle.
The tilt lever is located
on the driver’s side of the

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
Flash-to-Pass Feature
Windshield Wipers
Windshield Washer
Cruise Control (If Equipped)
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 isnished, the lever will return
automatically.
An arrow on the
instrument panel cluster
willash in the direction of
the turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts toash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
As you signal a turn or a lane change, if the arrows
don’tash but just stay on, 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 the fuse (seeFuses and Circuit Breakers
on page 5-89) and for burned-out bulbs.

toward you until you hear a click. Then release it.
When the high-beam
headlamps are on, this
indicator light on the
instrument panel cluster
will also be on.
Flash-To-Pass Feature
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, but not
so far that you hear a click.
If your headlamps are in the automatic position 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
N
WIPER:Turn the band with this symbol on it to
operate the windshield wipers.
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.
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:You can set the wiper speed for a
long or short delay between wipes. Turn the band
to choose the delay time. The closer to LO, the shorter
the delay.Be sure to clear ice and snow from the wiper blades
before using them. If they’re 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.
Windshield Washer
J
PUSH:Use this paddle to spray washeruid on the
windshield. The wipers will clear the window and then
either stop or return to your preset speed.
{CAUTION:
In freezing weather, don’t use your washer
until the windshield is warmed. Otherwise the
washer fluid can form ice on the windshield,
blocking your vision.

Cruise Control
If your vehicle is equipped
with cruise control, it is
located on a band at
the end of your turn
signal/multifunction lever.
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).{CAUTION:
•Cruise control can be dangerous where
you can’t drive safely at a steady speed.
So, don’t 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.
Don’t use cruise control on slippery roads.
