Wheel And Wheel Trim Care
All wheels and wheel trim, especially aluminum and
chrome plated wheels, should be cleaned regularly using
mild (neutral Ph) soap and water to maintain their luster
and to prevent corrosion. Wash wheels with the same soap
solution recommended for the body of the vehicle.
Your wheels are susceptible to deterioration caused by salt,
sodium chloride, magnesium chloride, calcium chloride,
etc., and other road chemicals used to melt ice or control
dust on dirt roads. Use a soft cloth or sponge and mild soap
to wipe away promptly. Do not use harsh chemicals or a
stiff brush. They can damage the wheel’s protective coating
that helps keep them from corroding and tarnishing.
CAUTION!
Avoid products or automatic car washes that use acidic
solutions or strong alkaline additives or harsh brushes.
Many aftermarket wheel cleaners and automatic car
washes may damage the wheel’s protective finish.
Such damage is not covered by the New Vehicle
Limited Warranty. Only car wash soap, Mopar Wheel
Cleaner or equivalent is recommended.When cleaning extremely dirty wheels including excessive
brake dust, care must be taken in the selection of tire and
wheel cleaning chemicals and equipment to prevent dam-
age to the wheels. Mopar Wheel Treatment or Mopar
Chrome Cleaner or their equivalent is recommended or
select a non-abrasive, non-acidic cleaner for aluminum or
chrome wheels.
CAUTION!
Do not use scouring pads, steel wool, a bristle brush,
metal polishes or oven cleaner. These products may
damage the wheel’s protective finish. Such damage is
not covered by the New Vehicle Limited Warranty.
Only car wash soap, Mopar Wheel Cleaner or equiva-
lent is recommended.
NOTE: If you intend parking or storing your vehicle for an
extended period after cleaning the wheels with wheel
cleaner, drive your vehicle and apply the brakes to remove
the water droplets from the brake components. This activ-
ity will remove the red rust on the brake rotors and prevent
vehicle vibration when braking.

IDENTIFICATION DATA
Vehicle Identification Number
The Vehicle Identification Number (VIN) is found on the
left front corner of the instrument panel, visible through
the windshield. This number also appears on the vehicle
frame and underbody as well as the Automobile Informa-
tion Disclosure Label affixed to a window on your vehicle,
the vehicle registration and title.
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 in-
crease 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 the “ABS Warning
Light” (if equipped) during brake use.
Hydraulic Brake Assist — 2500/3500 Models Only
(Except Power Wagon)
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.
