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.
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.
The battery could be drained if you leave the key
in the ACCESSORY or RUN position with the
engine off. You may not be able to start your
vehicle if the battery is allowed to drain for
an extended period of time.
D (START):This position starts the engine.

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 Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:

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.

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. 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.
