The windshield wiper/washer lever
is on the right side of the steering
column. With the ignition on or in
ACC/ACCESSORY, move the
windshield wiper lever to select the
wiper speed.
HI :Use for fast wipes.
LO : Use for slow wipes.
INT : Move the lever up to INT for
intermittent wipes, then turn the
x
INT band up for more frequent
wipes or down for less frequent
wipes.
OFF : Use to turn the wipers off.
1X : For a single wipe, briefly move
the wiper lever down. For several
wipes, hold the wiper lever down.
n L: Pull the windshield wiper
lever toward you to spray windshield
washer fluid and activate the wipers.
The wipers will continue until the
lever is released or the maximum
wash time is reached. When the
windshield wiper lever is released,
additional wipes may occur
depending on how long the
windshield washer had been
activated. See Washer Fluid0230
for information on filling the
windshield washer fluid reservoir.
{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.
Clear snow and ice from the wiper
blades and windshield before using
them. If frozen to the windshield,
carefully loosen or thaw them.
Damaged blades should be
replaced. See Wiper Blade
Replacement 0235.
Heavy snow or ice can overload the
wiper motor.
Wiper Parking
If the ignition is turned off while the
wipers are on LO, HI, or INT, they
will immediately stop.
If the windshield wiper lever is then
moved to OFF before the driver
door is opened or within 10 minutes,
the wipers will restart and move to
the base of the windshield.

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. SeeEngine
Compartment Overview 0217 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.
Brakes
Disc brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed.
The sound can come and go or can
be heard all the time when the
vehicle is moving, except when
applying the brake pedal firmly.
{Warning
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Caution
Continuing to drive with worn-out
brake pads could result in costly
brake repair.

of the vehicle in case it begins to
roll. Be ready to apply the regular
brake at once should the vehicle
begin to move.
