Use of a brake fluid that may have a lower initial
boiling point or unidentified as to specification, may
result in sudden brake failure during hard pro-
longed braking. You could have an accident.

Do not use abrasive or strong cleaning materials
such as steel wool or scouring powder, which will
scratch metal and painted surfaces.
Special Care
•
If you drive on salted or dusty roads or if you drive
near the ocean, hose off the undercarriage at least once
a month.
•It is important that the drain holes in the lower edges
of the doors, rocker panels and tailgate must be kept
clear and open.
•If you detect any stone chips or scratches in the paint,
touch them up immediately. The cost of such repairs is
considered the responsibility of the owner.
•If your vehicle is damaged due to an accident or
similar cause which destroys the paint and protective
coating have your vehicle repaired as soon as possible.
The cost of such repairs is considered the responsibil-
ity of the owner.
•Aluminum wheels should be cleaned regularly with a
mild soap and water to prevent corrosion. To remove
heavy soil, use MoparWheel Cleaner or select a
nonabrasive, non-acidic cleaner. Do not use scouring
pads, steel wool, a bristle brush or metal polishes.
Only Moparcleaners are recommended. Do not use
oven cleaner. Avoid automatic car washes that use
acidic solutions or harsh brushes that may damage the
wheels’ protective finish.
•If you carry special cargo such as chemicals, fertilizers,
de-icer salt, etc., assure that such materials are well
packaged and sealed.
