2012 JEEP GRAND CHEROKEE wiper blades

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.
Intermittent Wiper SystemUse one of the four intermittent wiper settings
when weather conditions make a single wiping
cycle, with a variable delay between cycles,
desirable. At driving speeds above 10 mph
(16 km/h), the delay can be regulated from a
maximum of approximately 18 seconds be-
tween cycles (first detent), to a cycle every one
second (fourth detent).
NOTE:
If the vehicle is moving less than 10 mph
(16 km/h), delay times will be doubled.

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 Fea-
tures)” in “Understanding Your Instru-
ment 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.
TILT/TELESCOPING STEERING
COLUMN
This feature allows you to tilt the steering col-
umn upward or downward. It also allows you to
lengthen or shorten the steering column. The
tilt/telescoping lever is located below the steer-
ing wheel at the end of the steering column. To unlock the steering column, push the lever
downward (toward the floor). To tilt the steering
column, move the steering wheel upward or
downward as desired. To lengthen or shorten
the steering column, pull the steering wheel
outward or push it inward as desired. To lock
the steering column in position, push the lever
upward until fully engaged.

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.
Rear Wiper Blade Removal/Installation
1. Lift the pivot cap on the rear wiper arm
upward, this will allow the rear wiper blade to
be raised off of the liftgate glass.
NOTE:
The rear wiper arm cannot be raised fully
upward unless the pivot cap is raised first.
2. Lift the rear wiper arm upward to raise the
wiper blade off of the liftgate glass.
3. Grab the bottom of the wiper blade and
rotate it forward to unsnap the blade pivot pin
from the wiper blade holder.

4. Install the wiper blade pivot pin into the
wiper blade holder at the end of the wiper arm,
and firmly press the wiper blade until it snaps
into place.
5. Lower the wiper blade and snap the pivot
cap into place.
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.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you uncon-
scious and can eventually poison you. To
avoid breathing CO, refer to “Safety Tips/
Exhaust Gas” in “Things To Do Before Starting
Your Vehicle” for further information.
CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will de-
stroy the effectiveness of the catalyst as an
emissions control device and may seriously
reduce engine performance and cause seri-
ous damage to the engine.
Under normal operating conditions, the cata-
lytic converter will not require maintenance.
However, it is important to keep the engine
properly tuned to assure proper catalyst opera-
tion and prevent possible catalyst damage.
