2018 JEEP WRANGLER UNLIMITED washer fluid

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.

CAUTION!
• Use of power washers exceeding
1,200 psi (8,274 kPa) can result in
damage or removal of paint and decals.
Some parts of the vehicle may be painted
with a matte paintwork which requires spe-
cial care for its preservation
CAUTION!
Avoid washing with rollers and/or brushes
in washing stations. Wash the vehicle only
by hand using neutral pH detergents; dry it
with a wet chamois leather. Abrasive prod-
ucts and/or polishes should not be used for
cleaning the car. Bird droppings must be
washed off immediately and thoroughly as
the acid they contain is particularly ag-
gressive. Avoid (if at all possible) parking
the vehicle under trees; remove vegetable
resins immediately as, when dried, it may
only be possible to remove them with abra-
sive products and/or polishes, which is
highly inadvisable as they could alter the
typical opaqueness of the paint. Do not
use pure windshield washer fluid for
CAUTION!
cleaning the front windshield and rear win-
dow; dilute it min. 50% with water. Only
use pure windshield washer fluid when
strictly necessary due to outside tempera-
ture conditions.
Special Care
• If you drive on salted or dusty roads or if you
drive near the ocean, hose off the undercar-
riage at least once a month.
• It is important that the drain holes in the
lower edges of the doors, rocker panels, and
trunk be kept clear and open.
• If you detect any stone chips or scratches in
the paint, touch them up immediately. The
cost of such repairs is considered the re-
sponsibility of the owner.
• If your vehicle is damaged due to a collision
or similar cause that destroys the paint and
protective coating, have your vehicle re-
paired as soon as possible. The cost of such
repairs is considered the responsibility of
the owner.• If you carry special cargo such as chemi-
cals, fertilizers, de-icer salt, etc., be sure
that such materials are well packaged and
sealed.
• If a lot of driving is done on gravel roads,
consider mud or stone shields behind each
wheel.
• Touch up the scratches as soon as possible.
An authorized dealer has touch up paint to
match the color of your vehicle.
Appearance Care For Fabric Top Models
To maintain the appearance of your vehicle's
interior trim and top, follow these precau-
tions:
• Avoid leaving your vehicle unattended with
the top down, as exposure to sun or rain
may damage interior trim.
• Do not use harsh cleaners or bleaching
agents on top material, as damage may
result.
• Do not allow any vinyl cleaner to run down
and dry on the paint, leaving a streak.
SERVICING AND MAINTENANCE
240

• After cleaning your vehicle's fabric top,
always make sure it is completely dry before
lowering.
• Be especially careful when washing the
windows by following the directions for
“Care of Fabric Top Windows.”
Washing –Use mild soap suds, lukewarm
water, and a brush with soft bristles. If extra
cleaning is required, use a mild foaming
cleaner on the entire top, but support the top
from underneath.
Rinsing –Be sure to remove all traces of
cleaner by rinsing the top thoroughly with
clean water. Remember to allow the top to dry
before lowering it.
CAUTION!
Failure to follow these cautions may cause
interior water damage, stains or mildew on
the top material:
• Avoid high-pressure car washes, as they
can damage the top material. Also, in-
creased water pressure may force past
the weather strips.
CAUTION!
• It is recommended that the top be free of
water prior to opening it. Operating the
top, opening a door or lowering a window
while the top is wet may allow water to
drip into the vehicle's interior.
• Use care when washing the vehicle, wa-
ter pressure directed at the weather strip
seals may cause water to leak into the
vehicle's interior.
• Careless handling and storage of the
removable roof panels may damage the
seals, causing water to leak into the
vehicle's interior.
• The front panel(s) must be positioned
properly to ensure sealing. Improper in-
stallation can cause water to leak into
the vehicle's interior.
Some parts of the vehicle may be painted
with a matte paintwork which requires spe-
cial care for its preservation.
CAUTION!
• Avoid washing with rollers and/or
brushes in washing stations. Wash the
vehicle only by hand using neutral pH
detergents; dry it with a wet chamois
leather. Abrasive products and/or pol-
ishes should not be used for cleaning the
car. Bird droppings must be washed off
immediately and thoroughly as the acid
they contain is particularly aggressive.
• Avoid (if at all possible) parking the
vehicle under trees; remove vegetable
resins immediately as, when dried, it
may only be possible to remove them
with abrasive products and/or polishes,
which is highly inadvisable as they could
alter the typical opaqueness of the
paint.
• Do not use pure windshield washer fluid
for cleaning the front windshield and
rear window; dilute it min. 50% with
water. Only use pure windshield washer
fluid when strictly necessary due to out-
side temperature conditions.
