2011 JEEP GRAND CHEROKEE wiper blades

High/Low Beam SwitchPush the multifunction lever toward the instru-
ment panel to switch the headlights to high
beam. Pulling the multifunction back toward the
steering wheel will turn the low beams back on,
or shut the high beams off.
WINDSHIELD WIPERS AND
WASHERS
The windshield wiper/washer control lever is
located on the left side of the steering column.
The front wipers are operated by rotating a
switch, located on the end of the lever. For
information on the rear wiper/washer, refer to
“Rear Window Features” in “Understanding the
Features of Your Vehicle”.
Windshield Wiper OperationRotate the end of the lever to one of the first four
detent positions for intermittent settings, the
fifth detent for low wiper operation and the sixth
detent for high wiper operation.CAUTION!
Always remove any buildup of snow that
prevents the windshield wiper blades from
returning to the “park” position. If the wind-
shield wiper switch is turned off, and the
blades cannot return to the “park” position,
damage to the wiper motor may occur.

MistUse the Mist feature when weather conditions
make occasional usage of the wipers neces-
sary. Rotate the end of the lever downward to
the Mist position and release for a single wiping
cycle.
Rain Sensing Wipers — If EquippedThis feature senses moisture on the windshield
and automatically activates the wipers for the
driver. The feature is especially useful for road
splash or overspray from the windshield wash-
ers of the vehicle ahead. Rotate the end of the
multifunction lever to one of four settings to
activate this feature.The sensitivity of the system can be adjusted
with the multifunction lever. Wiper delay posi-
tion 1 is the least sensitive, and wiper delay
position 4 is the most sensitive. Setting 3 should
be used for normal rain conditions. Settings 1
and 2 can be used if the driver desires less
wiper sensitivity. Settings 4 can be used if the
driver desires more sensitivity. Place the wiper
switch in the 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 func-
tion 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. •
A customer programmable feature in the
Electronic Vehicle Information Center
(EVIC) allows the Rain Sensing feature to
be turned off. Refer to “Electronic Vehicle
Information Center (EVIC)/Personal Set-
tings (Customer-Programmable Features)”
in “Understanding Your Instrument Panel”
for further information.
The Rain Sensing system has protection fea-
tures 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 ignition is ON, and the transmis-
sion 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 shift lever
is moved out of the NEUTRAL position.

attention should also be given to hood latching
components to ensure proper function. When
performing other underhood services, the hood
latch, release mechanism and safety catch
should be cleaned and lubricated.
The external lock cylinders should be lubri-
cated twice a year, preferably in the Fall and
Spring. Apply a small amount of a high quality
lubricant, such as MOPARLock Cylinder Lu-
bricant or equivalent directly into the lock cyl-
inder.
Windshield Wiper BladesClean the rubber edges of the wiper blades
and the windshield periodically with a sponge
or soft cloth and a mild nonabrasive cleaner to
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 wipe 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 de-
pending on geographical area and fre-
quency of use. Poor performance of blades
may be present with chattering, marks, wa-
ter lines or wet spots. If any of these condi-
tions are present, clean the wiper blades or
replace as necessary.
Adding Washer FluidThe fluid reservoir for the windshield washers
and the rear window washer is shared. The fluid
reservoir is located in the engine compartment,
be sure to check the fluid level at regular
intervals. Fill the reservoir with windshield
washer solvent only (not radiator antifreeze).
When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or
towel and wipe clean the wiper blades, 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 cli-
mate. 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.
Exhaust SystemThe best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained 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 under-
side or rear of the vehicle is damaged; have an
authorized technician inspect the complete ex-
haust system and adjacent body areas for
broken, damaged, deteriorated, or misposi-
tioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the
passenger compartment. In addition, inspect
the exhaust system each time the vehicle is
raised for lubrication or oil change. Replace as
required.
