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
Mopar Total Clean is specifically recommended
for leather upholstery.
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.
Stubborn soils can be removed easily with a soft
cloth and Mopar Total Clean. 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
upholstery. Application of a leather conditioner
is not required to maintain the original
condition.
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, and FCA recom
-
mends Mopar total care leather cleaner applied
on a cloth to clean the leather seats as needed.
GLASS SURFACES
All glass surfaces should be cleaned on a
regular basis with Mopar Glass Cleaner, or 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.
CAUTION!
Do not use Alcohol and Alcohol-based and/or
Ketone based cleaning products to clean
leather upholstery, as damage to the
upholstery may result.7

456TECHNICAL SPECIFICATIONS
NOTE:
Intentional tampering with the emissions
control system can result in civil penalties being
assessed against you.
CARBON MONOXIDE WARNINGS
FUEL REQUIREMENTS – DIESEL ENGINE
Use good quality diesel fuel from a reputable
supplier in your vehicle. Federal law requires
that you must fuel this vehicle with Ultra Low
Sulfur Highway Diesel fuel (15 ppm Sulfur
maximum) and prohibits the use of Low Sulfur
Highway Diesel fuel (500 ppm Sulfur maximum)
to avoid damage to the emissions control
system.
For most year-round service, No. 2 diesel fuel
meeting ASTM (formerly known as the American
Society for Testing and Materials) specification
D-975 Grade S15 will provide good
performance. If the vehicle is exposed to
extreme cold (below 20°F or -7°C), or is
required to operate at colder-than-normal
conditions for prolonged periods, use climatized
No. 2 diesel fuel or dilute the No. 2 diesel fuel
with 50% No. 1 diesel fuel. This will provide
better protection from fuel gelling or
wax-plugging of the fuel filters. Diesel fuel is seldom completely free of water.
To prevent fuel system trouble, drain the
accumulated water from the fuel/water
separator using the fuel/water separator drain
provided on both fuel filters. If you buy good
quality fuel and follow the cold weather advice
above, fuel conditioners should not be required
in your vehicle. If available in your area, a high
cetane “premium” diesel fuel may offer
improved cold-starting and warm-up
performance.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to
prevent carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in
a closed area, such as a garage, and never
sit in a parked vehicle with the engine
running for an extended period. If the
vehicle is stopped in an open area with the
engine running for more than a short
period, adjust the ventilation system to
force fresh, outside air into the vehicle.
Guard against carbon monoxide with
proper maintenance. Have the exhaust
system inspected every time the vehicle is
raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with
all side windows fully open.
WARNING!
Do not use alcohol or gasoline as a fuel
blending agent. They can be unstable under
certain conditions and hazardous or
explosive when mixed with diesel fuel.
CAUTION!
If the “Water in Fuel Indicator Light” remains
on, DO NOT START engine before you drain
the water from the fuel filter(s) to avoid
engine damage. Refer to “Draining Fuel/
Water Separator Filter” in “Servicing And
Maintenance” for further information.
