Telltale and warning lights

Technical equipment that
monitors itself

The function of telltale and warning
lights marked

●

is checked when the

ignition is switched on. They light up
just once, but for different lengths of
time.

If a defect occurs in one of the systems,
the corresponding light will remain on
when the engine is started or will come
on again during the journey. The correct
response to this on your part is
described below.

Red: stop immediately

Battery charge current

●

The battery is not charging.
There is a defect at the V-belt

for the alternator or in the alternator's
charging circuit. Have the system
checked.

If the V-belt is defective, do not
continue the journey, otherwise

the engine may overheat and be dam-
aged. A defective V-belt also means
more effort than usual is required to
turn the steering wheel.

Engine oil pressure

●

The engine oil pressure is too
low. Stop immediately and

switch off the engine. Do not continue
your journey. Have the system
checked.

Do not continue the journey, as
the engine may otherwise be

damaged by inadequate lubrication.

Brake warning light

Comes on even though the
handbrake has been released:

check brake fluid level. Before resum-
ing your journey, be sure to comply with
the instructions on page

. Have the

system checked without delay.

Runflat Indicator

●

In addition a warning signal is
heard: flat tyre. Reduce speed

and carefully bring the car to a stand-
still. Avoid abrupt braking and steering
manoeuvres.

Red and yellow: drive on, but
exercise restraint

If the brake warning light comes
on together with the yellow tell-
tale lights for ABS

●

and DSC:

The complete regulating sys-
tem for ABS, CBC, DSC and
ADB-X/DBC has failed. Drive
with care, looking at the traffic
situation well ahead, and avoid

heavy brake applications. Have the sys-
tem checked as soon as possible.
