CHECKING OIL LEVEL
To ensure proper engine lubrication, 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.
There are four possible dipstick types:
Crosshatched zone.
 Crosshatched zone marked SAFE.
 Crosshatched zone marked with MIN at the low end of
the range and MAX at the high end of the range.
 Crosshatched zone marked with dimples at the MIN
and the MAX ends of the range.
NOTE:Always maintain the oil level within the crosshatch
markings on the dipstick.
NOTE:Use care when filling under hood fluids such as engine oil,
washer fluid, antifreeze, etc., to minimize spillage onto the
top of the engine. Any excess fluid that is spilled onto the
top of the engine should be removed using compressed
air or an absorbent cloth.
Adding 1 qt (1 L) of oil when the reading is at the low end
of the dipstick range will raise the oil level to the high end
of the range marking.
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 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 solution or mixture that meets or
exceeds the temperature range of your climate. This rating
information can be found on most washer fluid containers.
NOTE:Use care when filling under hood fluids such as engine oil,
washer fluid, antifreeze, etc., to minimize spillage onto the
top of the engine. Any excess fluid that is spilled onto the
top of the engine should be removed using compressed
air or an absorbent cloth.
MAINTENANCE-FREE BATTERY
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, and periodic
maintenance is not required.
CAUTION!
Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage your
engine.
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!
Battery fluid is a corrosive acid solution and can burn
or even blind you. Do not allow battery fluid to
contact your eyes, skin, or clothing. Do not lean over
a battery when attaching clamps. If acid splashes in
eyes or on skin, flush the area immediately with large
amounts of water
Úpage 298.
 Battery gas is flammable and explosive. Keep flame
or sparks away from the battery. Do not use a
booster battery or any other booster source with an
output greater than 12 Volts. Do not allow cable
clamps to touch each other.
 Battery posts, terminals, and related accessories
contain lead and lead compounds. Wash hands after
handling.
 Vehicles with the Stop/Start system will be equipped
with two batteries. Both the main and the supple -
mental batteries must be disconnected to
completely de-energize the 12 Volt electrical system.
 Serious injury or death could result if you do not
disconnect both batteries. To learn how to properly
disconnect, see an authorized dealer.

gasoline engines or Úpage 311 for diesel engines.
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 ensure 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
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
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

1. Lift the wiper arm to raise the wiper blade off of the glass, until the wiper arm is in the full up position.

330SERVICING AND MAINTENANCE
NOTE:
It is the owner's responsibility to maintain the proper
level of protection against freezing according to the
temperatures occurring in the area where the vehicle is
operated.
 Use care when filling under hood fluids such as engine
oil, washer fluid, antifreeze, etc., to minimize spillage
onto the top of the engine. Any excess fluid that is
spilled onto the top of the engine should be removed
using compressed air or an absorbent cloth.
 Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could
lead to severe internal engine damage. If any coolant is
needed to be added to the system, please contact an
authorized dealer.
 Mixing engine coolant types is not recommended and
can result in cooling system damage. If HOAT and OAT
coolant are mixed in an emergency, have an authorized
dealer drain, flush, and refill with OAT coolant
(conforming to MS.90032) as soon as possible.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine
coolant (antifreeze), and to ensure that engine coolant will
return to the radiator from the coolant expansion bottle/
recovery tank if so equipped.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) OAT or
HOAT, is a regulated substance requiring proper disposal.
Check with your local authorities to determine the disposal
rules for your community. To prevent ingestion by animals
or children, do not store ethylene glycol-based coolant in
open containers or allow it to remain in puddles on the
ground, clean up any ground spills immediately. If
ingested, seek emergency assistance immediately.
Coolant Level
The coolant bottle provides a quick visual method for
determining that the coolant level is adequate. With the
engine OFF and cold, the level of the engine coolant
(antifreeze) in the bottle should be between the ranges
indicated on the bottle. The radiator normally remains completely full, so there is
no need to remove the radiator/coolant pressure cap
unless checking for engine coolant freeze point or
replacing coolant. Advise your service attendant of this. As
long as the engine operating temperature is satisfactory,
the coolant bottle need only be checked once a month.
When additional engine coolant is needed to maintain the
proper level, only OAT coolant that meets the
requirements of the manufacturer Material Standard
MS.90032 should be added to the coolant bottle. Do not
overfill.
Engine Coolant Level — 2.0L
WARNING!

Do not open hot engine cooling system. Never add
engine coolant (antifreeze) when the engine is over -
heated. Do not loosen or remove the cap to cool an
overheated engine. Heat causes pressure to build up
in the cooling system. To prevent scalding or injury,
do not remove the pressure cap while the system is
hot or under pressure.
 Do not use a pressure cap other than the one speci -
fied for your vehicle. Personal injury or engine
damage may result.

Care Of Fabric Top Windows
Your vehicle's fabric top has pliable plastic windows which
can be scratched unless special care is taken by following
these directions:
Never use a dry cloth to remove dust. Instead, use a
microfiber towel or soft cotton cloth moistened with
cold or warm, clean water, and wipe across the
window, not up and down. Mopar® Jeep® Soft Glass
Window Cleaner or equivalent will safely clean all
plastic windows without scratching. It removes fine
scratches to improve visibility and provides UV protec -
tion to help prevent yellowing.
 When washing, never use hot water or anything
stronger than a mild soap. Never use solvents such as
alcohol or harsh cleaning agents. 
Always rinse thoroughly with cold water, then wipe with
a soft and slightly moist, clean cloth.
 When removing frost, snow or ice, never use a scraper
or de-icing chemicals. Use warm water only if you must
clean the window quickly.
 Debris (sand, mud/dirt, dust, or salt) from off-road
driving will have an impact on plastic retainer opera -
tion. Even normal on-road driving and vehicle washing
will eventually impact window plastic retainer opera -
tion. To maintain ease of use of the window plastic
retainers, each window plastic retainer should be
cleaned and lubricated regularly. Clean them with a
mild soap solution and a small brush. Cleaning prod -
ucts are available through an authorized dealer.
 Never paste stickers, gummed labels or any tape to the
windows. Adhesives are hard to remove and may
damage the windows.
INTERIORS
CARPET SAFETY INFORMATION
Always use carpet designed to fit your vehicle. Only use
carpet that does not interfere with the operation of the
pedal assemblies. Only operate the vehicle when the
carpet is securely attached by the grommets so it cannot
slip out of position and interfere with the pedal assemblies
or impair safe operation of your vehicle in other ways.
CAUTION!
Failure to follow these cautions may cause interior
water damage, stains, or mildew of the top material:
Do not run a fabric top through an automatic car
wash. Window scratches and wax build-up may
result.
 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, water 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 installation can cause
water to leak into the vehicle’s interior.
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 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
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 opaque -
ness of the paint.
 Do not use pure windshield washer fluid for cleaning
the front windshield and rear window; dilute it to a
minimum of 50% water. Only use pure windshield
washer fluid when strictly necessary due to outside
temperature conditions.
CAUTION!
