Indicator and warning lamps

Technology that monitors itself

The system runs a check on the
warning and indicator lamps marked
by "

l

" each time you switch on the
ignition. They each light up once for dif-
ferent periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started or
it lights up while the vehicle is moving.
The following section describes how
you should respond.

sustain serious damage. A defective
drive belt will also make the vehicle
harder to steer.
