410SERVICING AND MAINTENANCE
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.
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. Dry with a soft cloth.
LEATHER SURFACES
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.
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 the manufacturer
recommends 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 rearview 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.

TECHNICAL SPECIFICATIONS
VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is found on the left front corner of the
instrument panel, visible through the windshield.
Vehicle Identification Number

NOTE:It is illegal to remove or alter the VIN.
BRAKE SYSTEM
If power assist is lost for any reason (for example,
repeated brake applications with the engine off),
the brakes will still function. However, you will
experience a substantial increase in braking effort
to stop the vehicle. If either the front or rear hydraulic system loses
normal braking capability, the remaining system
will still function with some loss of overall braking
effectiveness. This will be evident by increased
pedal travel during application, greater pedal force
required to slow or stop, and activation of the
Brake Warning Light and/or the Anti-Lock Brake
System (ABS) Warning Light during brake use.
HYDRAULIC BRAKE ASSIST —
I
F EQUIPPED
The brake system power assist is provided by a
hydro-boost unit which shares fluid with the power
steering system. You may experience some
clicking or hissing noises from the hydro-boost
system during hard braking conditions.
NOTE:Under cold temperatures, pedal effort will be
higher than normal until the power steering fluid
reaches operating temperature.
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 removed and
reinstalled on the vehicle, the lug nuts/bolts
should be torqued using a properly calibrated
torque wrench using a six-sided (hex) deep wall
socket.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended lug
nuts/bolts and clean or remove any dirt or oil
before tightening.

412TECHNICAL SPECIFICATIONS
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.
NOTE:Dual wheels are flat mounted, center piloted. The
lug nuts are a two-piece assembly. When the tires
are being rotated or replaced, clean these lug nuts
at the interface between the lug nut/bolt and the
washer. Do not oil wheel studs.

Two-Piece Lug Nut

Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.
Wheel Mounting Surface

Retighten the wheel nuts, in the same pattern, to
the torques listed in the Torque Specifications
table. Go through the sequence a second time to
verify that specific torque has been achieved.
Retighten to specifications after 25 miles (40 km)
and check the lug nut/bolt torque to be sure that
all the lug nuts/bolts are properly tightened.
8/10 Lug Nuts/Bolts Torque Patterns

It is recommended that wheel stud nuts be kept
torqued to specifications at all times. Torque wheel
stud nuts to specifications at each lubrication
interval.
1 — 10 Bolt Pattern
2 — 8 Bolt Pattern
