wiper blades JEEP GRAND CHEROKEE 2017 WK2 / 4.G Owners Manual

Windshield Wiper Operation
Rotate 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 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).

•The Rain Sensing feature can be turned on and off using
the Uconnect System, refer to “Uconnect Settings” in
“Multimedia” 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 3 mph (5 km/h), or the outside temperature is
greater than 32°F (0°C).
• Transmission In NEUTRAL Position — When the igni-
tion is ON, and the automatic transmission 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.
Remote Start Mode Inhibit — On vehicles equipped with
Remote Starting system, Rain Sensing wipers are not
operational when the vehicle is in the remote start mode.
Once the operator is in the vehicle and has placed the
ignition switch in the RUN position, rain sensing wiper
operation can resume, if it has been selected, and no other
inhibit conditions (mentioned previously) exist.Rear Window Wiper/Washer
The rear wiper/washer controls are located on the multi-
function 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.
Rotating the center portion upward once more will
activate the washer pump which will continue to
operate as long as the switch is held. Upon release of the

Checking Oil Level — Gasoline Engine
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
maintain 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.
CAUTION!
Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage your
engine.
Adding Washer Fluid
The instrument cluster display 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 solu-
tion or mixture that meets or exceeds the temperature
range of your climate. 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.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic mainte-
nance required.

proper function. When performing other underhood ser-
vices, the hood latch, release mechanism 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 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 products such as engine oil, gasoline, etc.NOTE:
Life expectancy of wiper blades varies depending
on geographical area and frequency of use. Poor perfor-
mance 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 follow-
ing 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.

WARNING!
The temperature grade for this tire is established for a
tire that is properly inflated and not overloaded. Ex-
cessive speed, under-inflation, or excessive loading,
either separately or in combination, can cause heat
buildup and possible tire failure.
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 battery 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 protec-
tive 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 surface 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 stationary 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 of
the system, thus minimizing the possibility of damage to
the compressor when the vehicle is put back into opera-
tion.
