9: Use to turn the wipers off.
When driving during the day and the
wipers are activated, the head
lamps automatically turn on after
completing eight wipe cycles.
Clear ice and snow from the wiper
blades before using them. If frozen
to the windshield, carefully loosen or
thaw them. Damaged blades should
be replaced.
Windshield Washer
The windshield wiper paddle is on
top of the turn signal lever.
L: 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.
{Warning
In freezing weather, do not use
the washer until the windshield is
warmed. Otherwise the washer
fluid can form ice on the
windshield, blocking your vision.
Compass
This vehicle may have a compass in
the Driver Information Center (DIC).
Compass Zone
Your dealer will set the correct zone
for your location.
Under certain circumstances, such
as during a long distance
cross-country trip or moving to a
new state or province, it will be
necessary to compensate for
compass variance by resetting the
zone through the DIC if the zone is
not set correctly.
Compass variance is the difference
between the earth's magnetic north
and true geographic north. If the
compass is not set to the zone
where you live, the compass may give false readings. The compass
must be set to the variance zone in
which the vehicle is traveling.
To adjust for compass variance, use
the following procedure:

What to UseCaution
Use of the incorrect fluid may
damage the vehicle and the
damages may not be covered by
the vehicle warranty. Always use
the correct fluid listed in
Recommended Fluids and
Lubricants0306.
To determine what kind of fluid to
use, see Recommended Fluids and
Lubricants 0306. Always use the
proper fluid. Failure to use the
proper fluid can cause leaks and
damage hoses and seals.
Washer Fluid
What to Use
When the vehicle needs windshield
washer fluid, be sure to read the
manufacturer's instructions before
use. If operating the vehicle in an
area where the temperature may fall below freezing, use a fluid that has
sufficient protection against
freezing.
Adding Washer Fluid
Open the cap with the washer
symbol on it. Add washer fluid until
the tank is full. See
Engine
Compartment Overview 0218 for
reservoir location.
Caution
. Do not use washer fluid that
contains any type of water
repellent coating. This can
cause the wiper blades to
chatter or skip.
(Continued)
Caution (Continued)
.Do not use engine coolant
(antifreeze) in the
windshield washer. It can
damage the windshield
washer system and paint.
. Do not mix water with
ready-to-use washer fluid.
Water can cause the
solution to freeze and
damage the washer fluid
tank and other parts of the
washer system.
. When using concentrated
washer fluid, follow the
manufacturer instructions for
adding water.
. Fill the washer fluid tank
only three-quarters full when
it is very cold. This allows
for fluid expansion if
freezing occurs, which could
damage the tank if it is
completely full.

Windshield and Wiper Blades
Clean the outside of the windshield
with glass cleaner.
Clean 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. Damage can be
caused by extreme dusty
conditions, sand, salt, heat, sun,
snow, and ice.
Weatherstrips
Apply Dielectric silicone grease on
weatherstrips to make them last
longer, seal better, and not stick or
squeak. Lubricate weatherstrips at
least once a year. Hot, dry climates
may require more frequent
application. Black marks from
rubber material on painted surfacescan be removed by rubbing with a
clean cloth. See
Recommended
Fluids and Lubricants 0306.
Tires
Use a stiff brush with tire cleaner to
clean the tires.
Caution
Using petroleum-based tire
dressing products on the vehicle
may damage the paint finish and/
or tires. When applying a tire
dressing, always wipe off any
overspray from all painted
surfaces on the vehicle.
Wheels and Trim —Aluminum
or Chrome
Use a soft, clean cloth with mild
soap and water to clean the wheels.
After rinsing thoroughly with clean
water, dry with a soft, clean towel.
A wax may then be applied.
Caution
Chrome wheels and other chrome
trim may be damaged if the
vehicle is not washed after driving
on roads that have been sprayed
with magnesium, calcium,
or sodium chloride. These
chlorides are used on roads for
conditions such as ice and dust.
Always wash the chrome with
soap and water after exposure.
Caution
To avoid surface damage, do not
use strong soaps, chemicals,
abrasive polishes, cleaners,
brushes, or cleaners that contain
acid on aluminum or
chrome-plated wheels. Use only
approved cleaners. Also, never
drive a vehicle with aluminum or
chrome-plated wheels through an
automatic car wash that uses
silicone carbide tire cleaning
