2018 JEEP WRANGLER UNLIMITED wiper blades

Windshield Wiper Operation
Rotate the end of the lever upward to the
second detent past the intermittent settings
for low-speed wiper operation. Rotate the end
of the lever upward to the third detent past
the intermittent settings for high-speed wiper
operation.
CAUTION!
In cold weather, always turn off the wiper
switch and allow the wipers to return to the
park position before turning off the en-
gine. If the wiper switch is left on and the
wipers freeze to the windshield, damage to
the wiper motor may occur when the ve-
hicle is restarted.
NOTE:
Do not operate the windshield wipers with the
blades lifted from the windshield.
Intermittent Wiper System
Use the intermittent wiper when weather
conditions make a single wiping cycle, with a
variable pause between cycles, desirable. Ro-tate the end of the lever to the first detent
position for one of four intermittent settings.
The delay cycle can be set anywhere between
1 to 18 seconds.
NOTE:
The wiper delay times depend on vehicle
speed. If the vehicle is moving less than
10 mph (16 km/h), delay times will be
doubled.
Windshield Washers
To use the washer, pull the lever toward you
and hold while spray is desired. If the lever is
pulled while in the delay range, the wiper will
start and continue to operate for two or three
wipe cycles after the lever is released. Then,
the intermittent interval previously selected
will resume.
If the lever is pulled while in the off position,
the wipers will operate for two or three wipe
cycles. Then, the wipers will turn off.
WARNING!
Sudden loss of visibility through the wind-
shield could lead to a collision. You might
WARNING!
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 Feature
Push upward on the wiper lever to activate a
single wipe to clear off road mist or spray
from a passing vehicle. As long as the lever is
held up, the wipers will continue to operate.
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.
Rear Window Wiper/Washer — If Equipped
A rotary switch on the center portion of the
windshield wiper/washer lever controls the
operation of the rear wiper/washer function.

Checking Oil Level — Gasoline Engine
WARNING!
• Never smoke while working in the engine
compartment: gas and inflammable va-
pors may be present, with the risk of fire.
• Be very careful when working in the
engine compartment when the engine is
hot: you may get burned. Do not get too
close to the radiator cooling fan: the
electric fan may start; danger of injury.
Scarves, ties and other loose clothing
might be pulled by moving parts.
CAUTION!
• Be careful not to confuse the various
types of fluids while topping up: they are
not compatible with each other! Topping
up with an unsuitable fluid could se-
verely damage your car.
• The oil level must never exceed the MAX
mark.
• Always top up using engine oil of the
same specifications as that already in
the engine.
CAUTION!
• If the engine oil is being topped up, wait
for the engine to cool down before loos-
ening the filler cap, particularly for ve-
hicles with aluminium cap (if
equipped). WARNING: risk of burns!
• Overfilling or underfilling the crankcase
will cause aeration or loss of oil pres-
sure. This could damage your engine.
To ensure proper lubrication of your vehicle's
engine, the engine oil must be maintained at
the correct level. The engine oil level should
be checked five minutes after a warmed up
engine has been 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
1 quart (0.95 liters) of oil when the reading is
at the bottom of the crosshatch zone will
result in a reading at the top of the cross-
hatch zone on these engines.
Adding Washer Fluid
The fluid reservoir for the windshield washers
and the rear window washer (if equipped) is
shared. The fluid reservoir is located in the
engine compartment. Be sure to check the
fluid level at regular intervals. Fill the reser-
voir 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 perfor-
mance.
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 rat-
ing information can be found on most washer
fluid containers.
WARNING!
Commercial windshield washer solvents
are flammable. They could ignite and burn
you. Care must be exercised when filling or
working around the washer solution.

WARNING!
work for which you have the knowledge
and the proper equipment. If you have any
doubt about your ability to perform a ser-
vice job, take your vehicle to a competent
mechanic.
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.
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.
