Rotate the end of the lever upward, to the first detent past the
intermittent settings for low-speed wiper operation. Rotate
the end of the lever upward to the second detent past the
intermittent settings for high-speed wiper operation.
Intermittent Wiper System
The intermittent feature of this system was designed for use
when weather conditions make a single wiping cycle, with a
variable pause between cycles, desirable. For maximum
delay between cycles, rotate the control knob upward to the
first detent.
The delay interval decreases as you rotate the knob until it
enters the low continual speed position. The delay can be
regulated from a maximum of about 18 seconds between
cycles, to a cycle every one second. The delay intervals will
double in duration when the vehicle speed is 10 mph
(16 km/h) or less.
Windshield Washers
To use the windshield washer, push the washer knob,
located on the end of the multifunction lever, inward and
hold. Washer fluid will be sprayed and the wiper will
operate for two to three cycles after the washer knob is
released.If the washer knob is depressed while in the delay range, the
wiper will operate for several seconds after the washer knob
is released. It will then resume the intermittent interval
previously selected. If the washer knob is pushed while in
the off position, the wiper will turn on and cycle approxi
-
mately three times after the wash knob is released.
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.
Mist Feature
When a single wipe to clear off road mist or spray from a
passing vehicle is needed, push the washer knob, located on
the end of the multifunction lever, inward briefly and
release. The wipers will cycle one time and automatically
shut off.
WARNING!
Sudden loss of visibility through the windshield could
lead to a collision. You might not see other vehicles or
other obstacles. To avoid sudden icing of the windshield
during freezing weather, warm the windshield with the
defroster before and during windshield washer use.

GETTING TO KNOW YOUR VEHICLE 77
NOTE:
The mist feature does not activate the washer pump; there-
fore, no washer fluid will be sprayed on the windshield. The
wash function must be used in order to spray the windshield
with washer fluid.
Rain Sensing Wipers — If Equipped
This feature senses rain and snowfall on the windshield and
automatically activates the wipers for the driver. The feature
is especially useful for road splash or overspray from the
windshield washers of the vehicle ahead. Rotate the end of
the multifunction lever to one of four settings to activate this
feature.
NOTE:
This feature can be programmed through the Uconnect
system. Refer to “Uconnect Settings” in “Multimedia” for
further information.
The sensitivity of the system can be adjusted with the multi -
function lever. Wiper delay position 1 is the least sensitive,
and wiper delay position 4 is the most sensitive.
NOTE:
Position 3 should be used for normal rain conditions. Positions 1 and 2 can be used if the driver desires less wiper
sensitivity. Position 4 can be used if the driver desires more
sensitivity. Place the wiper switch in the O (off) position
when not using the system.
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 windshield.
• 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
placed in the ON position, 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 (N) Position — When the
ignition is ON, and the transmission is in the NEUTRAL
position, the Rain Sensing system will not operate until the

Checking Oil Level
To assure proper lubrication of your vehicle's engine, the
engine oil must be maintained at the correct level. Check the
oil level at regular intervals, such as every fuel stop. The best
time to check the engine oil level is about five minutes after
a fully warmed up engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always main-
tain the oil level within the SAFE zone on the dipstick.
Adding one quart of oil when the reading is at the bottom of
the SAFE zone will result in a reading at the top of the safe
zone on these engines.
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.
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 solu-
tion used with water as directed on the container, aids
cleaning action, reduces the freezing point to avoid line clog
-
ging, and is not harmful to paint or trim.
CAUTION!
Overfilling or underfilling will cause oil aeration or loss
of oil pressure. This could damage your engine.
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.

SERVICING AND MAINTENANCE 503
Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the wind-
shield 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 petro -
leum products such as engine oil, gasoline, etc.
NOTE:
Life expectancy of wiper blades varies depending on
geographical area and frequency of use. Poor performance 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 peri
-
odically, not just when wiper performance problems are
experienced. This inspection should include the following
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.
