NOTE:
•The Rain Sensing feature will not operate when the
wiper switch is in the low or high-speed position.
• The Rain Sensing feature may not function properly
when ice, or dried salt water is present on the wind-
shield.
• Use of Rain-X or products containing wax or silicone
may reduce Rain Sensing performance.
The Rain Sensing system has protection features for the
wiper blades and arms, and will not operate under the
following conditions:
• Low Ambient Temperature — When the ignition is first
turned ON, the Rain Sensing system will not operate
until the wiper switch is moved, vehicle speed is greater
than 0 mph (0 km/h), or the outside temperature is
greater than 32°F (0°C). •
Transmission In NEUTRAL Position — When the igni-
tion is ON, and the transmission is in the NEUTRAL
position, the Rain Sensing system will not operate until
the wiper switch is moved, vehicle speed is greater than
5 mph (8 km/h), or the gear selector is moved out of the
NEUTRAL position.
• Remote Start Mode Inhibit — On vehicles equipped
with Remote Starting system, Rain Sensing wipers are
not operational when the vehicle is in the remote start
mode. Once the operator is in the vehicle and has placed
the ignition switch in the RUN position, rain sensing
wiper operation can resume, if it has been selected, and
no other inhibit conditions (mentioned previously) exist.

Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth and a
mild nonabrasive cleaner. This will remove accumulations
of salt or road film.
Operation of the wipers on dry glass for long periods may
cause deterioration of the wiper blades. Always use washer
fluid when using the wipers to remove salt or dirt from a
dry windshield.
Avoid using the wiper blades to remove frost or ice from
the windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
NOTE:Life expectancy of wiper blades varies depending
on geographical area and frequency of use. Poor perfor-
mance of blades may be present with chattering, marks,
water lines or wet spots. If any of these conditions are
present, clean the wiper blades or replace as necessary. The wiper blades and wiper arms should be inspected
periodically, not just when wiper performance problems
are experienced. This inspection should include the follow-
ing points:
•
Wear Or Uneven Edges
• Foreign Material
• Hardening Or Cracking
• Deformation Or Fatigue
If a wiper blade or wiper arm is damaged, replace the
affected wiper arm or blade with a new unit. Do not
attempt to repair a wiper arm or blade that is damaged.
Wiper Blade Removal/Installation
CAUTION!
Do not allow the wiper arm to spring back against the
glass without the wiper blade in place or the glass may
be damaged.

Installing The Front Wipers
1. Lift the wiper arm off of the glass, until the wiper arm isin the full up position.
2. Position the wiper blade under the hook on the tip of the wiper arm with the wiper locking tab open.
3. Insert the receiver bracket on the wiper assembly into the hook on the tip of the arm through the opening in
the wiper blade under the locking tab.
4. Slide the wiper blade up into the hook on the wiper arm until it is latched (engagement will be accompanied by
an audible click). Fold down the latch release tab and
snap it into its locked position.
5. Gently lower the wiper blade onto the glass.
Adding Washer Fluid
The fluid reservoir is located under the hood and should be
checked for fluid level at regular intervals. Fill the reservoir
with windshield washer solvent only (not radiator anti-
freeze). When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or towel and wipe
the wiper blades clean. This will help blade performance.
To prevent freeze-up of your windshield washer system in
cold weather, select a solution or mixture that meets or exceeds the temperature range of your climate. This rating
information can be found on most washer fluid containers.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around the
washer solution.
After the engine has warmed up, operate the defroster for
a few minutes to reduce the possibility of smearing or
freezing the fluid on the cold windshield. Windshield
washer solution used with water as directed on the con-
tainer, aids cleaning action, reduces the freezing point to
avoid line clogging, and is not harmful to paint or trim.
Exhaust System
The best protection against carbon monoxide entry into the
vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system;
or if the exhaust fumes can be detected inside the vehicle;
or when the underside or rear of the vehicle is damaged;
