Notes on the oil level Depending on drivin
gstyle, the vehicle con-
sumes amaximum of 0.8 loil per 100 0km.
Th eo il consumption may be higher than this
when the vehicle is new or if you frequently
drive at high engine speeds.
When checking the oil level:
R park the vehicle on alevel surface.
R the engine should be switched off for at
least fiv eminutes if the engine is at normal
operating temperature.
R the engine should be switched off for at
least thirt yminutes if the engine is not at
normal operating temperature, e.g. if the
engine was only started briefly.
Checking the oil level using the oil dip-
stick Depending on the engine, the oil dipstick may
be installed at
adifferent location. E3

i Depending on the engine, the difference
between the minimum mark and the maxi-
mum mark is approximately 1.5 –2litres.
! Do not add too muc hoil. If the oil level is
above the "max "mark on the dipstick, too
much oil has been added. This can lead to

Risk of inju
ry
Fo rs afety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz. Thes ebatteries provide
increased impact protection to prevent vehi-
cle occupant sfrom suffering aci dburns
should the battery be damaged in the event
of an accident.
To prevent acid burns, observe the following
safety notes when handling batteries:
R do not lean over the battery.
R do not place any metal objects on abattery.
Otherwise ,you coul dcause ashort circuit
and the battery's gas mixtur ecould ignite.
R mak esure that you do not create an elec-
trostatic charge, e.g. by wearing synthetic
clothing or as aresult of friction on fabrics.
Therefore, you should not pull or slide the
batter yover carpets or other synthetic
materials.
R neve rtouch the battery first. To discharge
ap ossible electrostatic charge, step out of
the vehicle first and touc hthe bodywork.
R do not wipe the battery usin gacloth. The
battery may explode as aresult of electro-
static charge or due to flying sparks.
! Switc hoff th eengine and remove the key
before disconnectin gthe termi nalclamps
from the battery .Onvehicles with KEY-
LE SS -GO, make sure that the ignition is
switched off. Check that all the indicator
lamps in the instrument cluste rare off.
Otherwise, yo umay destroy electronic
components, such as the alternator.
i Remove the key if you park the vehicle
and do not require any electrical consum-
ers. The vehicle will then use very little
energy, thus conserving battery power.
Mercedes-Benz recommends that you do not
carr yout work on batteries yourself, e.g.
removing, charging or replacing. Always have this work performed at
aqualified specialist
workshop, e.g. aMercedes-Ben zService
Cent re. Installation location of the battery

X Turn the key to position 0(Ypage 135) in
the ignition lock and remove it, or, with
KEYLESS-GO, make sure that the ignition
has bee nswitched off (Y page 135). All

Only charge the batter yinawell-ventilated
area. As the battery is being charged ,gases
can escape and generate minor explosions.
This could injure you and other persons or
cause damage to the paintwork or acid cor-
rosion on the vehicle.
You can obtain information about battery
chargers which allow the battery to be
charged while still installed from aqualified
specialist workshop ,e.g. aM ercedes-Benz

Risk of injury
There is arisk of acid burns when jump-starting avehicle due to the gases which escape from
the battery. Do not lean over the batter ywhile the engin eisbeing jump-started. G
Risk of explosion
Gases escapin gfrom th ebattery during jump-starting may cause minor explosions. Avoid cre-
ating sparks. Keep naked flames away from the battery, and do not smoke.
Comply with safety precautions when handling batteries. You will find these under "Battery" in
the index.
! Avoid repeated and lengthy startin gattempts. Otherwise, non-combuste dfuel may dam-
age the catalytic converter 41
and create arisk of fire.
Do not use arapid-charging device to start the engine.
Make sure the jump leads are not damaged.
Make sure the jump leads are not touching any other metal objects when they are connected
to the battery.
If your vehicle's battery is discharged ,the engin ecan be jump-started from another vehicle
or from asecond batter yusing jum pleads.
Observ ethe followin gpoints:
X The battery is not accessible in all vehicles. If the other vehicle' sbattery is not accessible,
jump-start the vehicle using asecond batter yorajump-star ting device.
X Only jump-start the vehicl ewhen th eengineisc old an dthe catalytic converter system has
cooled down 42
.
X Do no tstart the engine if the battery is frozen. Let the battery thaw first.
X Jump-starting may only be performed from batterie swithanominal voltage of 12 V.
X Only use jum pleads which have asufficient cross-section and insulated terminal clamps.
X Make sure that the jump leads cannot come into contact with parts, such as the pulley or
the fan. Thes eparts move when the engine is started and while it is running.
X If the battery is fully discharged ,leave the batter ythat is being used to jump-star tconnected
for afew minutes befor eattempting to start. This charges the battery alittle.
i Jump leads and further information about jump-startin gcan be obtained from any
Mercedes-Ben zService Centre.
X Make sure that the two vehicles do not touch.
X Apply the parking brak efirmly.
