2018 JEEP GRAND CHEROKEE wiper blades

WINDSHIELD WIPERS AND
WASHERS
The windshield wiper/washer controls are lo-
cated on the multifunction lever 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
Wiper/Washer” in this section.
Windshield Wiper Operation
Rotate the end of the lever to one of the first
four detent positions for intermittent set-
tings, 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
windshield wiper switch is turned off, and
the blades cannot return to the “park”
position, damage to the wiper motor may
occur.
Intermittent Wiper System
Use one of the four intermittent wiper set-
tings 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 regu-
lated from a maximum of approximately
18 seconds between 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.
Windshield Washer Operation
To use the washer, push on the end of the
lever (toward the steering wheel) and hold
while spray is desired. If the lever is pushed
while in the intermittent setting, the wipers
will turn on and operate for several wipe
cycles after the end of the lever is released,
and then resume the intermittent interval
previously selected.
If the end of the lever is pushed while the
wipers are in the off position, the wipers will
operate for several wipe cycles, then turn off.
WARNING!
Sudden loss of visibility through the wind-
shield 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 wind-
shield with the defroster before and during
windshield washer use.

Mist
Use the Mist feature when weather condi-
tions make occasional usage of the wipers
necessary. Rotate the end of the lever down-
ward to the MIST position and release for a
single wiping cycle.
NOTE:
The Mist feature does not activate the washer
pump; therefore, no washer fluid will be
sprayed on the windshield. The wash func-
tion must be used in order to spray the
windshield with washer fluid.
Rain Sensing Wipers — If Equipped
This feature senses rain or 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.
The sensitivity of the system can be adjusted
with the multifunction lever. Wiper delay po-
sition one is the least sensitive, and wiper
delay position four is the most sensitive.NOTE:
Wiper delay position three should be used for
normal rain conditions.
Settings one and two can be used if the driver
desires less wiper sensitivity. Setting four 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 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 perfor-
mance.
• The Rain Sensing feature can be turned on
and off using the Uconnect System, refer to
“Uconnect Settings” in “Multimedia” in
the Owners Manual 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 igni-
tion is first turned ON, the Rain Sensing
system will not operate until the wiper
switch is moved, vehicle speed is greater
than 3 mph (5 km/h), or the outside tem-
perature is greater than 32°F (0°C).
•Transmission In NEUTRAL Position— When
the ignition is ON, and the automatic trans-
mission is in the NEUTRAL position, the
Rain Sensing system will not operate until
the wiper switch is moved, vehicle speed is
greater than 3 mph (5 km/h), or the gear
selector is moved out of the NEUTRAL
position.Rear Window Wiper/Washer
The rear wiper/washer controls are located on
the multifunction lever on the left side of the
steering column. The rear wiper/washer is
operated by rotating a switch, located at the
middle of the lever.
Rotate the center portion of the lever upward
to the first detent for intermittent operation
and to the second detent for continuous rear
wiper operation.

voir, 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 tempera-
ture range of your climate. This rating infor-
mation 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.

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 prod-
ucts such as engine oil, gasoline, etc.
NOTE:
Life expectancy of wiper blades varies de-
pending 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 periodically, 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.
Front 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.

arm, grasp the bottom end of the wiper
blade nearest to wiper arm with your right
hand. With your left hand hold the wiper
arm as you pull the wiper blade away from
the wiper arm past its stop far enough to
unsnap the wiper blade pivot pin from the
receptacle on the end of the wiper arm.
NOTE:
Resistance will be accompanied by an
audible snap.
4. Still grasping the bottom end of the wiper
blade, move the wiper blade upward and
away from the wiper arm to disengage.
5. Gently lower the tip of the wiper arm onto
the glass.
Installing The Rear Wiper
1. Lift the rear wiper arm pivot cap away
from the glass to allow the rear wiper
blade to be raised off of the glass.NOTE:
The rear wiper arm cannot be fully raised
off the glass unless the wiper arm pivot
cap is unsnapped first. Attempting to fully
raise the rear wiper arm without unsnap-
ping the wiper arm pivot cap may damage
the vehicle.
2. Lift the rear wiper arm fully off the glass.
3. Insert the wiper blade pivot pin into the
opening on the end of the wiper arm. Grab
the bottom end of the wiper arm with one
hand, and press the wiper blade flush with
the wiper arm until it snaps into place.
4. Lower the wiper blade onto the glass and
snap the wiper arm pivot cap back into
place.

These effects can be reduced by timely rota-
tion of tires. The benefits of rotation are
especially worthwhile with aggressive tread
designs such as those on On/Off-Road type
tires. Rotation will increase tread life, help to
maintain mud, snow, and wet traction levels,
and contribute to a smooth, quiet ride.
Refer to the “Maintenance Plan” for the
proper maintenance intervals. More frequent
rotation is permissible if desired. The reasons
for any rapid or unusual wear should be
corrected prior to rotation being performed.
NOTE:
The premium Tire Pressure Monitor System
will automatically locate the pressure values
displayed in the correct vehicle position fol-
lowing a tire rotation.
The suggested rotation method is the
“rearward-cross” shown in the following dia-
gram.
STORING THE VEHICLE
If the vehicle should remain stationary for
more than a month, observe the following
precautions:
• Park your vehicle in a covered, dry and
possibly airy location the windows open
slightly.
• Check that the Electric Park Brake is not
engaged.
• Disconnect the negative (-) terminal from
the battery post and be sure that the battery
is fully charged. During storage check bat-
tery charge quarterly.• If you do not disconnect the battery from
the electrical system, check the battery
charge every 30 days.
• Clean and protect the painted parts by
applying protective waxes.
• Clean and protect polished metal parts by
applying protective waxes.
• Apply talcum powder to the front and rear
wiper blades and leave raised from the
glass.
• Cover the vehicle with an appropriate cover
taking care not to damage the painted sur-
face by dragging across dirty surfaces. Do
not use plastic sheeting which will not allow
the evaporation of moisture present on the
surface of the vehicle.
• Inflate the tires at a pressure of +7.25 psi
(+0.5 bar) higher than recommended on
the tire placard and check it periodically.
• Do not drain the engine cooling system.
• Whenever you leave the vehicle is station-
ary for two weeks or more, run idle the
engine for approximately five minutes, with
the air conditioning system on and high fan
speed. This will ensure a proper lubrication
