Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
G:Turn and Lane Change Signals.
53:Headlamp High/Low-Beam Changer.
N:Windshield Wipers.
L:Windshield Washer.
Flash-to-Pass Feature.
Information for these features is on the pages following.
Turn and Lane-Change Signals
G:An arrow on the instrument panel cluster flashes
in the direction of the turn or lane change.
To signal a turn, move the lever all the way up or down.
To signal a lane change, raise or lower the lever until
the arrow starts to flash. The turn signal automatically
flashes three times and if the tow-haul mode is active
it flashes six times. Holding the turn signal lever for
more than one second causes the turn signals to
flash continually until the lever is released.
The lever returns to its starting position when released.
If after signaling a turn or lane change the arrow
flashes rapidly or does not come on, a signal bulb
may be burned out.
Have the bulbs replaced. If the bulb is not burned out,
check the fuse. SeeFuses and Circuit Breakers on
page 5-105.
Turn Signal On Chime
If the turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime sounds at each flash of the turn signal
and the message TURN SIGNAL ON also appears in
the Driver Information Center (DIC). SeeDIC Warnings
and Messages on page 3-48. To turn off the chime
and message, move the turn signal lever to the
off position.
3-7
Headlamp High/Low-Beam Changer
23(Headlamp High/Low-Beam Changer):Pull the
turn signal lever all the way toward you to change the
headlamps from low to high beam. Then release it.
This instrument panel cluster light comes on when the
high beam headlamps are on.
Flash-to-Pass
This feature is used to signal to the vehicle ahead that
you want to pass.
If the headlamps are off or in the low-beam position,
pull the turn signal lever toward you to momentarily
switch to high-beams.
Release the lever to turn the high-beam headlamps off.
Windshield Wipers
The windshield wiper control is located on the
multifunction lever on the left side of the steering wheel.
Turn the band with
Non it to the following positions:
8(Mist):For a single wiping cycle, hold the band
on mist until the wipers start, then let go. The wipers
will stop after one wipe. If more wipes are needed,
hold the band on mist longer.
6Delay:Turn the band to adjust the delay time between
wipes. The closer to the top of the lever, the shorter
the delay.
d(Low Speed):For steady wiping at low speed.
a(High Speed):For steady wiping at high speed.
9(Off):Turns the wipers off.
When driving during the day and the wipers are
activated, the head lamps automatically turn on after
completing eight wipe cycles.
Be sure to clear ice and snow from the wiper blades
before using them. If they are frozen to the windshield,
carefully loosen or thaw them. If the blades become
damaged, get new blades or blade inserts.
3-8
Windshield Washer
The windshield wiper paddle is located on top of the
multifunction lever.
L(Washer Fluid):Push the paddle to spray washer
fluid on the windshield. The wipers will clear the window
and then either stop or return to the preset speed.
{CAUTION:
In freezing weather, do not use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking your
vision.
Cruise Control
{CAUTION:
Cruise control can be dangerous where you cannot
drive safely at a steady speed. So, do not use the
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 excessive wheel slip, and you could lose
control. Do not use cruise control on slippery roads.
With cruise control, a speed of about 25 mph (40 km/h)
or more can be maintained without keeping your foot
on the accelerator. Cruise control does not work
at speeds below about 25 mph (40 km/h).
When the brakes are applied, cruise control is
turned off.
If the vehicle has StabiliTrak
®, and the system begins
to limit wheel spin, cruise control will automatically
disengage. SeeStabiliTrak
®System on page 4-5. When
road conditions allow the cruise control to be safely used
again, it can be turned back on.
3-9
Windshield and Wiper Blades
Clean the outside of the windshield with glass cleaner.
Clean the rubber blades using a lint free cloth or
paper towel soaked with windshield washer fluid or
a mild detergent. Wash the windshield thoroughly when
cleaning the blades. Bugs, road grime, sap, and a
buildup of vehicle wash/wax treatments may cause
wiper streaking. Replace the wiper blades if they are
worn or damaged.
Wipers can be damaged by:
•Extreme dusty conditions
•Sand and salt
•Heat and sun
•Snow and ice, without proper removal

thoroughly, dry with a soft clean towel. A wax may then
be applied.
Notice:Using chrome polish on aluminum wheels
could damage the wheels. The repairs would not
be covered by the warranty. Use chrome polish
on chrome wheels only.
The surface of these wheels is similar to the painted
surface of the vehicle. Do not use strong soaps,
chemicals, abrasive polishes, abrasive cleaners,
cleaners with acid, or abrasive cleaning brushes
on them because the surface could be damaged.
Do not use chrome polish on aluminum wheels.
