Windshield Wipers
Clear ice and snow from the wiper
blades before using them. If the
wiper blades are frozen to the
windshield, gently loosen or thaw
them. If the blades do become
damaged, install new blades or
blade inserts. SeeWindshield Wiper
Blade Replacement on page 9-21.
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 lever on the right side of the
steering column operates the
windshield wipers. Push up or pull
down on the lever to place it in
one of the following positions.
[(High):For rapid wiping cycles.
— (Low):For slow, steady wiping
cycles.
-- (Intermittent/RainSense™):
See RainSense™ wipers below.
9(Off):Turns off the wipers.For a single wipe pull the lever
down from the off position. The lever
will return to its original position.
For more cycles, hold the lever
down before releasing it.
RainSense™ Wipers
There is a moisture sensor mounted
on the windshield next to the inside
rearview mirror. When active, the
sensor is able to detect moisture on
the windshield and automatically
control the frequency of the wipes
according to the weather conditions.
To turn on the RainSense feature,
the wipers must be set to the
intermittent delay setting on
the windshield wiper lever.
To turn off RainSense, move the
lever downwards.
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.

For quicker cool down, do the
following:
1. Press
#to turn on the air
conditioning.
2. Select
Ymode.
3. Set the temperature knob to the
coldest temperature.
4. Set the fan knob to 4.
5. Open all vents.
Recirculation
^(Recirculation):Press to
turn the recirculation mode on or off.
An indicator light inside the button
comes on when the recirculation
mode is active. This mode
recirculates air inside the passenger
compartment and prevents outside
air from entering the vehicle.The quality of the passenger
compartment air may decrease
since the amount of outside
air entering the vehicle is reduced.
When the recirculation mode is
used without air conditioning, the
air humidity increases, and the
windows may fog. Avoid using the
recirculation mode during high
periods of humidity or cool outside
temperatures since this may result in
increased window fogging. If window
fogging is experienced, select the
defrost mode.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
The rear window defogger will only
work when the ignition is in
ON/RUN.
=(Rear Window Defogger):
Press to turn the rear window
defogger on or off. An indicator
light inside the button will be lit
when in use.
If your vehicle has heated mirrors,
they turn on when the rear window
defogger button is pressed. Press
the button again to turn them off.
For more information, seeOutside
Power Mirror(s) on page 2-12.
The rear window defogger will stay
on for approximately 15 minutes
after the button is pressed, unless
the ignition is turned off.
Notice:Do not use anything
sharp on the inside of the rear
window. If you do, you could cut
or damage the warming grid, and
the repairs would not be covered
by the vehicle warranty. Do not
attach a temporary vehicle
license, tape, a decal or anything
similar to the defogger grid.
