Topping up the engine oil H
Environmental note
When topping up the oil, take care not to spill
any. Oil must not be allowed to escape into
the soil or waterways. You would otherwise be
damaging the environment. Cap (example)
X
Turn cap :anti-clockwise and remove.
X Top up with the amount of oil required
(Y page 289).
i The difference in quantity between the
minimum mark and maximum mark is
approximately 2 litres.
! Do not add too much oil. If too much oil
is added and the oil level is above the max-
imum mark on the dipstick, the engine or
catalytic converter could be damaged.
Have excess oil siphoned off.
X Replace cap :on the filler neck and
tighten clockwise.
Ensure that the cap locks into place
securely.
For further information on engine oil, see
(Y page 289). Coolant
Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down.
X Turn the key to position 2(Y page 63) in
the ignition lock.
X Check the coolant temperature gauge in
the multi-function display. G
Risk of injury

Risk of accident and injury
The operating safety of your vehicle could be compromised if service work is carried out improp-
erly. You could lose control of the vehicle and cause an accident. Safety systems may also not
be able to protect you or others as intended.
Always have maintenance work carried out at a qualified specialist workshop. The workshop must
have the necessary specialist knowledge and tools to carry out the work required. Mercedes-
Benz recommends that you use a Mercedes-Benz Service Centre for this purpose. In particular,
work relevant to safety or on safety-related systems must be carried out at a qualified specialist
workshop. Display messages

Problem
Possible causes/consequences and
X
X Solutions Vehicles with a petrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is a malfunction in the engine electronics or a mechanical
component of the engine control unit.
X
Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at a qualified specialist
workshop.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it. The coolant tempera-
ture gauge shows a
value above 120 †.
You also hear a warning
tone. The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X
Stop as soon as possible and allow the engine and the coolant
to cool down.
X Check the coolant level (Y page 177). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct, the radiator fan may be faulty. The
coolant is too hot and the engine is no longer being cooled suffi-
ciently.
X
If the coolant temperature is less than 120 †, you can continue
driving to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving on
mountain roads and stop/start driving. The engine does not
switch off. The ignition lock is faulty.
X
Open the fuse box in the engine compartment (Y page 281).
X Remove fuse 120 using the fuse extractor.
The engine stops.
If you wish to start the engine again:
X Replace the fuse. Troubleshooting
