switched off and that the key has been
pulled out of the ignition lock before open-
ing the bonnet.
The bonnet release lever is located in the
driver's footwell. 1

X Pull bonnet release lever 1.
The bonnet is released.
! Make sure that the windscreen wipers
are not folded out away from the wind-
screen. You can otherwise damage the
windscreen wipers or the bonnet. The handle for opening the bonnet is located
above the radiator grille.

Risk of injury
Make sure that nobody can become trap-
ped as you close the bonnet.
X Lower the bonnet and let it fall from a
height of approximately 20 cm.
X Check that the bonnet has engaged prop-
erly. i
If the bonnet can be raised slightly, it is
not properly engaged. Open it again and
close it with a little more force. Engine oil
Depending on driving style, the vehicle con-
sumes a maximum of 0.8 l oil per 1,000 km.
The oil consumption may be higher than this
when the vehicle is new or if you frequently
drive at high engine speeds. You can only
estimate the oil consumption after you have
driven a considerable distance.
You will find further information about engine
oil in the "Technical data" section
(Y page 369).
Checking the engine oil level To do so:
R
the vehicle should be parked on level
ground.
R the engine should be switched off for at
least five minutes if the engine was at nor-
mal operating temperature.
R the engine should be switched off for at
least 30 minutes if the engine was not at Operation

operating temperature (i.e. if you only star-
ted the engine briefly).
Via the on-board computer*
i Only possible on the ML 420 CDI. On all
other models a dipstick is used to check
the engine oil level (Y page 222).
X Make sure that the key is in position
2(Y page 75) in the ignition lock.
X Press the jork button to select the
following message: The measurement takes a few seconds. You
will see one of the following messages in the
display:
R
Engine oil level OK
R Add 1.0 litre to reach maximum oil
level R
Add 1.5 litres to reach maximum oil
level
R Add 2.0 litres to reach maximum oil
level
X Top up the oil if necessary ( Ypage 222).
Other messages in the multi-function dis-
play
If the engine is at normal operating tempera-
ture and there is too much oil, you will see the
following message:
Eng. oil level
Reduce oil level
X Have excess oil siphoned off.
! There is a risk of damage to the engine or
the catalytic converter if there is excess oil
in the engine.
If the Switch ignition on to check
engine oil level message appears:
X Turn the key to position 2(Y page 75) in
the ignition lock.
You will see the following message if you did
not observe the required waiting period:
Observe waiting period X
Repeat the measurement after about five
minutes if the engine is at normal operating
temperature.
X Repeat the measurement after about
30 minutes if the engine is not at normal
operating temperature (if the engine was
only started briefly).
The following message appears if the engine
is running:
Engine oil level Not when engine on
X Switch off the engine and wait for five
minutes if the engine is at normal operating
temperature, or for about 30 minutes if the
engine is not at normal operating temper-
ature (if the engine was only started
briefly), before measuring.
i If you wish to cancel the measurement,
press the korj button on the multi-
function steering wheel. Operation

Coolant
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
i When the vehicle is first delivered, it is
topped up with a coolant that will ensure
adequate antifreeze and corrosion protec-
tion.
! Only top up with coolant that has been
premixed with the desired antifreeze pro-
tection. You could otherwise damage the
engine. There is more information about coolant
and topping it up on Mercedes-Benz Spec-
ifications for Service Products Sheet
310.1.
! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the cooling system will not be
sufficiently protected from corrosion, and
the boiling point will be too low.
If antifreeze/corrosion inhibitor is present in
the correct concentration, the boiling point of
the coolant will be around 130 °C.
The antifreeze/corrosion inhibitor concentra-
tion in the cooling system should: R
be at least 50%. This will protect the cooling
system against freezing down to around
–37 °C.
R not exceed 55% concentration (antifreeze
protection down to –45 °C), otherwise heat
will not be effectively dissipated.
If the vehicle has lost coolant, top it up with
equal amounts of water and antifreeze/cor-
rosion inhibitor. Mercedes-Benz recom-
mends using an antifreeze/corrosion inhibi-
tor which has been approved for Mercedes-
Benz vehicles.
! The cooling system contains a filling
which must be renewed after 15 years, or
after 250, 000 km at the latest. Have the
renewal confirmed in the Service Booklet.

372 Brake fluid
Over a period of time, the brake fluid absorbs
moisture from the air; this lowers its boiling
point. G
Risk of accident
If the boiling point of the brake fluid is too
low, vapour pockets may form in the brake
system when the brakes are applied hard
(e.g. when driving downhill). This would
impair braking efficiency.
Have the brake fluid renewed every two
years with a brake fluid that has been
approved by Mercedes-Benz and have this
confirmed in the Service Booklet. i
There is usually a notice in the engine
compartment to remind you when the next
brake fluid change is due. Windscreen washer system
The washer fluid reservoir holds approxi-
mately 7.2 litres.
The headlamp cleaning system* and the
windscreen washer system are both supplied
from the washer fluid reservoir.
X At temperatures above freezing point:
Top up the washer fluid reservoir with a
mixture of water and windscreen washer
concentrate (Y page 223).
X At temperatures below freezing point:
Top up the washer fluid reservoir with a
mixture of water, antifreeze and wind-
screen washer concentrate (Y page 223).
Adapt the mixing ratio to the outside tem-
peratures. G
Risk of fire
Windscreen washer concentrate is highly
flammable. Fire, naked flames and smoking
are prohibited when windscreen washer
concentrate is being handled. Technical data
