2015 JEEP GRAND CHEROKEE wiper blades

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 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
between cycles (first detent), to a cycle every one second
(fourth detent).

176 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Rain Sensing Wipers — If Equipped
This 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 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 position one is the least
sensitive, and wiper delay position four is the most
sensitive. Setting 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 wind-
shield.
•Use of Rain-X® or products containing wax or silicone
may reduce Rain Sensing performance.
•The Rain Sensing feature can be turned on and off
using the Uconnect® System, refer to “Uconnect®
Settings” in “Understanding Your Instrument Panel”
for further information.
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 tem-
perature is greater than 32°F (0°C).

the glove compartment travel stops.
NOTE:Ensure the glove compartment door hinges and
glove compartment travel stops are fully engaged.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, decklid, sliding doors and hood hinges, should
be lubricated periodically with a lithium based grease,
such as MOPAR® Spray White Lube to assure quiet, easy
operation and to protect against rust and wear. Prior to
the application of any lubricant, the parts concerned
should be wiped clean to remove dust and grit; after
lubricating excess oil and grease should be removed.
Particular attention should also be given to hood latching
components to ensure proper function. When performing
other underhood services, the hood latch, release mecha-
nism and safety catch should be cleaned and lubricated.The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant, such as MOPAR®
Lock Cylinder Lubricant directly into the lock cylinder.
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 accumula-
tions 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.
546 MAINTAINING YOUR VEHICLE

NOTE:Life expectancy of wiper blades varies depend-
ing 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 neces-
sary.
The wiper blades and wiper arms should be inspected
periodically, not just when wiper performance problems
are experienced. This inspection should include the fol-
lowing points:
•Wear Or Uneven Edges
•Foreign Material
•Hardening Or Cracking
•Deformation Or FatigueIf 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.
1. Lift the wiper arm to raise the wiper blade off of the
glass, until the wiper arm is in the full up position.

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
unsnapping 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.Adding Washer Fluid
This vehicle is equipped with a Driver Information
Display (DID), the DID will indicate when the washer
fluid level is low. When the sensor detects a low fluid
level, the windshield will light on the vehicle graphic
outline and the “WASHER FLUID LOW” message will be
displayed.
The 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 climate. This
