•A stiff-bristle brush and lukewarm soapywater can be used to clean the wiper blades.Frequent cleaning of the windshield andwiper blades improves visibility considerablyand also helps prolong the service life of thewiper blades.
•Wash off the dirt from the underside (wheelhousings, fenders, etc).
•In areas of high industrial fallout, more fre-quent washing is recommended.

CAUTION
•During high pressure washing, the spraymouthpiece must never be closer to thevehicle than 13" (30 cm). Do not sprayinto the locks.

Automatic car washes
•We do NOT recommend washing your car inan automatic wash during the first few
months (because the paint will not havehardened sufficiently).
•An automatic wash is a simple and quick wayto clean your car, but it is worth rememberingthat it may not be as thorough as when youyourself go over the car with sponge andwater. Keeping the underbody clean is mostimportant, especially in the winter. Someautomatic washers do not have facilities forwashing the underbody.
