2013 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).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

208 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•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 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 Settings
(Customer-Programmable Features)” in “Understand-
ing 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 notoperate 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).
•Transmission In NEUTRAL Position— When the
ignition is ON, and the transmission is in the NEU-
TRAL 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.
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.

CAUTION!
The A/C air filter is identified with an arrow to
indicate airflow direction through the filter. Failure
to properly install the filter will result in the need to
replace it more often.
7. Rotate the glove compartment door back into position.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, sliding doors and hood hinges, should be lubri-
cated periodically with a lithium based grease, such as
MOPAR® Spray White Lube to assure quiet, easy opera-
tion 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. Particularattention should also be given to hood latching compo-
nents 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 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 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.
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 up-
ward unless the pivot cap is raised first.
2. Lift the rear wiper arm upward to raise the wiper
blade off of the liftgate glass.1 — Wiper Arm
2 — Pivot Cap 622 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.
