238 MAINTAINING YOUR VEHICLEPlastic and Rubber PartsDo not use oil or wax on these parts.
Do not use any caustic or alcohol-based or solvent-
based substances to clean plastic surfaces.
Avoid the use of stain removers, iodine tincture, nail
varnish and nail varnish remover, acetone, methylated
spirits, chlorine or ammonium-based cleaning agents,
cleaning agents containing abrasive substances.ELECTRICAL FUSESDamaged fuses are recognizable from their burnt-out
filament.
Prior to exchanging a fuse, turn the key in the ignition-
column lock to the 0 position and switch off the
consumer involved.
NOTE: Fuses must not be bridged. Replace fuses with
specified rated current. Only replace fuses when the
cause of the malfunction has been rectified.
NOTE: Fuses and relays (standard equipment) are on
the underside of the ignition column, refer to "Fuses
and Relays Standard Equipment". Fuses, relays and diodes (optional equipment) are
below the driver’s seat, refer to "Optional Fuse and
Relay Equipment".
CAUTION!
When replacing a blown fuse, it is important to
use only a fuse having the correct amperage
rating. The use of a fuse with a rating other than
indicated may result in a dangerous electrical
system overload. If a properly rated fuse
continues to blow, it indicates a problem in the
circuit that must be corrected.
