The vehicle has fuses to protect
against an electrical system
overload. Fuses also protect power
7443 W21/
devices in the vehicle.

Replace a bad fuse with a new one

of the identical size and rating.
If there is a problem on the road and
a fuse needs to be replaced, there
is a fuse puller in the Engine
Compartment Fuse Block. Replace
the fuse as soon as possible with
one of the same amperage rating.
Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have the
headlamp wiring checked right away
if the lamps go on and off or
remain off.
