With the key in steering lock position 2, an
indicator lamp comes on. It should go out
when the engine is running.
If the warning lamp does not go out after starting the
engine, or if it comes on while driving, this lamp
indicates a failure in the parking lamp, taillamp, stop
lamp, or low beam headlamp.
If an ex terior la mp fa il s, t he indicator la mp w ill c ome on
only when that lamp is switched on.
If a brake lamp fails, the lamp failure indicator will
come on when applying the brake and stays on until the
engine is turned off.
Note:
If additional lighting equipment is installed (e.g.
auxiliary headlamps etc.) be certain to connect into the
fuse before the failure indicator monitoring unit in
order to avoid damaging the system.Additional function indicator lamps

Coolant level
To check the coolant level, the vehicle must be parked
on level ground and the engine stopped.
Check coolant level only when coolant is cold.
Adding coolant
If coolant has to be add ed, a 50/50 mix ture of water and
MB anticorrosion / antifreeze should be added. Refill
coolant until the float in the reservoir reaches and
closes the filler opening. Anticorrosion / antifreeze, see page 256. The drain plugs for the cooling system are
located on the right side of the engine block and at the
bottom of the radiator.
P20.20-2052-26
Wa r n i n g !
In order to avoid possible serious burns or injury:
• Use extreme caution when opening the hood if
there are any signs of steam or coolant leaking
from the cooling system, or if the coolant
temperature gauge indicates that the engine is
overheated.• Do not remove pressure cap on coolant
reservoir if engine temperature is above 194°F
(90°C). Allow engine to cool down before
removing cap. The coolant reservoir contains
hot fluid and is under pressure.• Using a rag, slowly open cap approximately
1/2 turn to relieve excess pressure. If opened
immediately, scalding hot fluid and steam will
be blown out under pressure.
• Do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which may
burn if it comes into contact with hot engine
parts.
