Charge Indicator Lamp

Should the charge indicator lamp fail to

come on prior to starting when the key

is in steering lock position 2 or should

it fail to go out after starting or during

operation, this indicates a fault which

must be repaired at an authorized

MERCEDES-BENZ dealer

immediately.

If the charge indicator lamp comes on

while the engine is running, this may

indicate that the poly-V-belt has

broken. Should this condition occur,

the poly-V-belt must be replaced before

continuing to operate the vehicle.

Otherwise, the engine will overheat due

to an inoperative water pump which

may result in damage to the engine.

Engine Oil Pressure Gauge with Oil

Pressure-Warning Lamp

With the key in steering lock position

2, the oil pressure warning lamp comes

on and goes out with the engine

running.

The oil pressure at idle speed may drop

if the engine is at operating temperature.

This will not jeopardize the engine's

operational reliability.

Pressure must, however, rise

immediately upon acceleration.

Note:

If the oil pressure warning lamp does

not go out after starting the engine or

comes on while driving and the oil

pressure gauge needle drops to "0",

then damage to the engine may occur

with continued operation. Turn off

engine immediately and contact an

authorized Mercedes-Benz dealer. Do

not operate the car until the condition

is repaired.

There is no need for concern should the

oil pressure warning lamp light up

briefly, (for example, in sharp turns or

hard braking) provided the lamp goes

out immediately. We recommend you

to drive to the nearest service station

where the engine oil should be topped

to the "full" mark on the dipstick with

an approved oil.
