Topping up engineo il !
Use only engine oils and oil filters that are
approved for vehicles with aservice system. A
list of the engine oils and oil filters that have
been tested and approved in accordance with
Mercedes-Benz Specifications for Service
Products is available at any Mercedes-Benz
Service Centre. Engine compartment
213Maintenance and care Z

The following cause engine failure or damage
to the exhaust system:
R Use of engine oils and oil filters that have
not been expressly approved for the service
system
R Replacement of engine oil and oil filter after
the replacement interval specified by the
service system has expired
R Use of engine oil additives
! Do not add too much oil. If the oil level is
above the "max" mark on the dipstick ,too
much oil has been added. This can lead to
damage to the engine or the catalytic con-
verter .Have excess oil siphoned off. H
Environmental note
When topping up the oil, take care not to spill
any. If oil enters the soil or waterways, it is
harmful to the environment. X
Turn cap :anti-clockwise and remove it.
X Top up with the amount of engine oil required.
Observe the specification sinthe on-board com-
puter when doing so or fill carefully to the max- imum mark on the oil dipstick.
The differenc ebetween the minimum mark and
the maximum mark on the oil dipstick is approx- imately 2.0 litres.
X Replace cap :on the filler neck and turn
clockwise.
Make sure that the cap locks securely into
place.

Important safety notes G
WARNING
Certain components in the engin ecompart-
ment coul dbevery hot, e.g. the engine, the
radiator and parts of the exhaust system.
There is arisk of injury when accessing the
engine compartment.
As far as possible,a llow the engine to cool
downa nd only touch the components descri-
bed in the following. G
WARNING
There are moving components in the engine
compartment. Certain components may con-
tinue to move or suddenly move again even
after the ignitio nhas been switched off, e.g.
the radiator fan. There is arisk of injury.
If you have to carry out work in the engine
compartment:
R switch off the ignition
R never touch the dangerous area ssurround-
ing moving components, e.g. the rotation
area of the fan
R remove jewellery and watches
R keep items of clothing and hair, for exam-
ple,a wayfrom moving parts. G
WARNING
The cooling system is pressurised ,particu-
larl yw hen the engine is warm .Ifyou open the
cap, you coul dbescalded if hot coolant
sprays out. There is arisk of injury.
Let the engine cool downb efore you open the
cap. Wearg lovesand eye protection. Open
the cap slowly to release the pressure. G
WARNING
If you open the bonnet while the engine is
overheating or while there is afire in the
engine compartment, you coul dcome into
contact with hot gase sorother leaking ser-
vice products. There is adange rofinjury. 214

For further information on displaying this mes-
sage, refe rtothe "Checking the tyre pressure
electronically" section (Y page 240).
Important safety notes It is the driver's responsibility to set the tyre
pressure to the recommended cold tyre pres-
sure suitable for the operating situation
(Y page 238). Note that the correc ttyre pres-
sure for the current operating situation must
first be learnt by the tyre pressure monitor. If a
substantial loss of pressure occurs, the warning threshold for the warning message is aligned to
the learnt reference values. Restart the tyre
pressure monitor after adjusting to the cold tyre pressure (Y page 241). The current pressures
are saved as new reference values. This ensures that awarning message appears only if the tyre
pressure drops significantly.
The tyre pressure monitor does not warn you of
an incorrectly set tyre pressure. Observe the
notes on the recommended tyre pressure
(Y page 238).
The tyre pressure monitor is not abletow arn
you of asudden loss of pressure, e.g. if the tyre
is penetrated by aforeign object. In this event,
bring the vehicle to ahalt by braking carefully.
Avoid abrupt steering manoeuvres.
The tyre pressure monitor has ayellow h
warning lamp on the instrument cluster for indi-
cating apressure loss or malfunction. Depend-
ing on how the warning lamp flashe sorlights up,
at yre pressure that is too low or amalfunction in
the tyre pressure monitor is indicated:
R if the h warning lamp is lit continuously,
the tyre pressure on one or more tyres is sig-
nificantly too low. The tyre pressure monitor
is not malfunctioning.
R if the h warning lamp flashe sfor around a
minute and then remains lit constantly, the
tyre pressure monitor is malfunctioning.
In addition to the hwarning lamp,am essage
appears in the multifunction display. Observe
the information on display messages
(Y page 150).
It may take up to ten minutes for amalfunction
of the tyre pressure monitor to be indicated .A
malfunction willbei ndicated by thehtyre
pressure warning lamp flashing for approx-
imatel yone minute and then remaining lit. When
the faulth as been rectified, the htyre pres-
sure warning lamp goes out after driving for a
few minutes. The tyre pressure values indicated by the on-
board computer may differ from those meas-
ured at
afilling station using apressure gauge.
The tyre pressures shown by the on-board com-
puter refer to those measured at sea level. At
high altitudes, the tyre pressure values indica-
ted by apressure gauge are higher than those
shown by the on-board computer. In this case,
do not reduce the tyre pressures.
The operation of the tyre pressure monitor can
be affected by interferenc efrom radio transmit-
ting equipment (e.g. cordless headphones, two- way radios) that may be being operated in or
near the vehicle.
