thoroughly and frequently, at least once a
month, with lukewarm or cold water.

paint surface could be scratched. Here are
some examples of how scratching could
occur.

rinsing off dirt and other foreign matter.
The vehicle is washed with a rough, dry,

or dirty cloth.
The vehicle is washed at a car wash that

uses brushes that are dirty or too stiff.
Cleansers or wax containing abrasives

are used.
NOTE
Mazda is not responsible for scratches

caused by automatic car washes or
improper washing.
Scratches are more noticeable on

vehicles with darker paint finishes.

To minimize scratches on the vehicle's
paint finish:
Rinse off any dirt or other foreign matter

