XUnscrew filler cap : from filler neck.XAdd engine oil as required. Be careful not
to overfill with oil.
Be careful not to spill any oil when adding.
Avoid environmental damage caused by oil
entering the ground or water.
! Excess oil must be siphoned or drained
off. It could cause damage to the engine
and emission control system not covered
by the Mercedes-Benz Limited Warranty.
XScrew filler cap : back on filler neck.
For more information on engine oil, see the
“Technical data” section (Y page 252) and
(Y page 253).
Brake fluid level
! If you find that the brake fluid in the brake
fluid reservoir has fallen to the minimum
mark or below, have the brake system
checked for brake pad thickness and leaks
immediately. Contact an authorized
Mercedes-Benz Center immediately. Do
not add brake fluid as this will not solve the
problem. For more information, see
“Practical hints”.
When checking the brake fluid level, the
vehicle must be parked on level ground.
The brake fluid level is correct when it is
between lower mark (MIN) ; and upper
mark (MAX) : of the brake fluid reservoir.
Coolant level
The engine coolant is a mixture of water and
anticorrosion/antifreeze.
When checking the coolant level, the vehicle
must be parked on level ground, and the
coolant temperature must be below 158‡
(70†).
GWarning!
In order to avoid any potentially serious burns:
RUse 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 coolant is overheated.
RDo not remove pressure cap on coolant
reservoir if coolant temperature is above
158‡ (70†). Allow engine to cool down
before removing cap. The coolant reservoir
contains hot fluid and is under pressure.
RUsing a rag, slowly open the cap
approximately 1/2 turn to relieve excess
pressure. If opened immediately, scalding
hot fluid and steam will be blown out under
pressure.
RDo not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which
may burn if it comes into contact with hot
engine parts.
