Ignition Positions
Use the key to turn the ignition switch to
four different positions.
A (LOCK):This position locks the ignition and
transmission. It is a theft-deterrent feature. You will
only be able to remove the key when the ignition
is turned to LOCK.Notice:Using a tool to force the key from
the ignition switch could cause damage
or break the key. Use the correct key and turn
the key only with your hand. Make sure the
key is all the way in. If it is, turn the steering
wheel left and right while you turn the key
hard. If none of this works, then your vehicle
needs service.
B (ACCESSORY):This position lets you use
things like the radio and the windshield wipers
when the engine is off.
Notice:Lengthy operation of features such as
the radio in the accessory ignition position
and the RUN position may drain the battery and
prevent your vehicle from starting. Do not
operate your vehicle in the accessory ignition
position for a long period of time.
C (RUN):This is the position for driving. It is the
position the switch returns to after the engine
starts, and you release the key.
D (START):This position starts the engine.

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 538.

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, seeWindshield Wiper Blade
Replacement on page 478.
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.
You control the windshield wipers by turning the
band with the wiper symbol on it.
8(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 wipe.
If you want more wipe cycles, hold the band
on mist longer.
(Delay):You can set the wiper speed 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):For steady wiping at low
speed, turn the band away from you to the
rst solid band past the delay settings.
1(High Speed):For high-speed wiping, turn
the band further, to the second solid band past the
delay settings.
9(Off):To stop the wipers, move the band
to off.

Rainsense™ II Wipers
Your vehicle has Rainsense™ II windshield
wipers. These wipers automatically turn on when
a sensor, mounted next to the inside rearview
mirror, detects moisture on the windshield. When
active, these wipers 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. 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 three, 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 off to high speed
according to the weather conditions. The wipers
can be left in a Rainsense™ mode even when it
is not raining.
When Rainsense™ II is active, the headlamps will
turn on automatically after approximately eight
wipes. The headlamps will turn off if the wiper
switch is set to a delay position, and there have
been no wipes for approximately three minutes, or
if the wiper switch is turned to the off position. If
it is dark outside, the headlamps will remain on.
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.

Windshield Washer
{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.
L(Washer Fluid):There is a paddle marked
with the windshield washer symbol at the top of the
multifunction lever. To spray washer uid on the
windshield, push the paddle. The wipers will
clear the window and then either stop or return to
your preset speed.
Heated Windshield Washer
If your vehicle has the heated windshield washer
uid system it may be used to help clear ice,
snow, tree sap, or bugs from your windshield.
The button is located in
the switchbank under
the climate controls.
Push the heated washer uid button to activate
the heated windshield washer uid system.
The indicator light will ash. This activation will
initiate four heated wash/wipe cycles. The
rst heated wash/wipe cycle may take up to
40 seconds to occur, depending on outside
temperature.
198

After the rst wash/wipe cycle, it may take up to
20 seconds for each of the remaining cycles
to begin. Press the button again to turn off the
heated windshield washer uid system or it
will automatically turn off after four wipe cycles
have been completed.
When the heated windshield washer uid system
is activated under certain outside temperature
conditions, steam may ow out of the washer
nozzles for a short period of time before washer
uid is sprayed. This is a normal condition.
Rear Window Wiper/Washer

washer until the windshield is warmed.
