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.
SERVICING AND MAINTENANCE

• 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.

Care Of Fabric Top Windows
Your vehicle's fabric top has pliable plastic
windows which can be scratched unless spe-
cial care is taken by following these direc-
tions:
• Never use a dry cloth to remove dust. In-
stead,use a microfiber towel or soft cotton
cloth moistened with cold or warm, clean
water, and wipe across the window, not up
and down.It removes fine scratches to im-
prove visibility and provides UV protection
to help prevent yellowing.
• When washing,never use hot wateror any-
thing 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 plas-
tic retainer operation. Even normal on-road
driving and vehicle washing will eventually
impact window plastic retainer operation. 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 products 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
Seats And Fabric Parts
Use a specific product to clean fabric uphol-
stery and carpeting.
WARNING!
Do not use volatile solvents for cleaning
purposes. Many are potentially flam-
mable, and if used in closed areas they
may cause respiratory harm.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with
chemical solvents or abrasive cleaners. This
will weaken the fabric. Sun damage can also
weaken the fabric.
If the belts need cleaning, use a mild soap
solution or lukewarm water. Do not remove
the belts from the vehicle to wash them. Dry
with a soft cloth.
Replace the belts if they appear frayed or
worn or if the buckles do not work properly.
WARNING!
A frayed or torn belt could rip apart in a
collision and leave you with no protection.
Inspect the belt system periodically,
checking for cuts, frays, or loose parts.
Damaged parts must be replaced immedi-
ately. Do not disassemble or modify the
system. Seat belt assemblies must be re-
placed after a collision if they have been
damaged (i.e., bent retractor, torn web-
bing, etc.).SERVICING AND MAINTENANCE

Plastic And Coated Parts
Use a specific product to clean vinyl
upholstery.
CAUTION!
• Direct contact of air fresheners, insect
repellents, suntan lotions, or hand sani-
tizers to the plastic, painted, or deco-
rated surfaces of the interior may cause
permanent damage. Wipe away immedi-
ately.
• Damage caused by these type of prod-
ucts may not be covered by your New
Vehicle Limited Warranty.
Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this
vehicle are molded in clear plastic. When
cleaning the lenses, care must be taken to
avoid scratching the plastic.1. Clean with a wet soft cloth. A mild soap
solution may be used, but do not use high
alcohol content or abrasive cleaners. If
soap is used, wipe clean with a clean
damp cloth.
2. Dry with a soft cloth.
Leather Parts
Your leather upholstery can be best preserved
by regular cleaning with a damp soft cloth.
Small particles of dirt can act as an abrasive
and damage the leather upholstery and
should be removed promptly with a damp
cloth. Care should be taken to avoid soaking
your leather upholstery with any liquid.
Please do not use polishes, oils, cleaning
fluids, solvents, detergents, or ammonia-
based cleaners to clean your leather uphol-
stery. Application of a leather conditioner is
not required to maintain the original condi-
tion.
NOTE:
If equipped with light colored leather, it tends
to show any foreign material, dirt, and fabric
dye transfer more so than darker colors. The
leather is designed for easy cleaning.
CAUTION!
Do not use Alcohol and Alcohol-based
and/or Ketone based cleaning products to
clean leather seats, as damage to the seat
may result.
Glass Surfaces
All glass surfaces should be cleaned on a
regular basis with any commercial
household-type glass cleaner. Never use an
abrasive type cleaner. Use caution when
cleaning the inside rear window equipped
with electric defrosters or windows equipped
with radio antennas. Do not use scrapers or
other sharp instruments that may scratch the
elements.
When cleaning the rear view mirror, spray
cleaner on the towel or cloth that you are
using. Do not spray cleaner directly on the
mirror.

VEHICLE IDENTIFICATION
NUMBER
The Vehicle Identification Number (VIN) is
found on the left front corner of the A pillar,
visible from outside of the vehicle through
the windshield. This number also appears
underbody, on the right side of the frame rail
near the center of the vehicle, as well as on
the Automobile Information Disclosure Label
affixed to a window on your vehicle. Save this
label for a convenient record of your vehicle
identification number and optional equip-
ment.
The VIN is also stamped on either right or left
hand side of the engine block.NOTE:
It is illegal to remove or alter the VIN plate.
WHEEL AND TIRE TORQUE
SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to
the vehicle. Any time a wheel has been re-
moved and reinstalled on the vehicle, the lugnuts/bolts should be torqued using a properly
calibrated torque wrench using a high quality
six sided (hex) deep wall socket.
