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.

Headlamp High/Low-Beam Changer
53(Headlamp High/Low Beam Changer):
To change the headlamps from low to high beam,
push the lever toward the instrument panel. To
return to low-beam headlamps, pull the
multifunction lever toward you. Then release it.
When the high beams
are on, this indicator light
on the instrument panel
cluster will also be on.
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 in the automatic position.
To use it, pull the turn signal lever toward you,
then release it.
If your headlamps are in the automatic position or
on low beam, your high-beam headlamps will turn
on. They will stay on as long as you hold the levertoward you. The high-beam indicator on the
instrument panel cluster will come on. Release the
lever to return to normal operation.
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 481
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.

N(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
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 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 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 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 8 wipes.
The headlamps will turn off if the wiper switch is set
to the delay position, and there have been no wipes
for approximately 3 minutes or it has become light
enough outside. 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.

washer until the windshield is warmed.

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 be on. 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

nozzles for a short period of time before washer
uid is sprayed. This is a normal condition.
