2014 JEEP GRAND CHEROKEE wiper blades

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).

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).

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.
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.
524 MAINTAINING YOUR VEHICLE

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
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 System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained 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 underside or rear of the vehicle is damaged;
have an authorized technician inspect the complete ex-
haust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams
or loose connections could permit exhaust fumes to seep
into the passenger compartment. In addition, have the
exhaust system inspected each time the vehicle is raised
for lubrication or oil change. Replace as required.
