Notes on changing bulbs
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that all bulbs function correctly at all times. G
Risk of injury
Bulbs and lamps can be very hot. Yo u
should therefore allow them to cool down
before you change them. Otherwise, you
could be burned if you touch them.
Keep bulbs out of the reach of children.
Otherwise, they could damage them, for
example, and injure themselves.
Never use a bulb which has been dropped.
Such a bulb may explode and injure you.
H7 bulbs are pressurised and could explode
when you change them, particularly if they
are very hot. You should therefore wear eye
protection and gloves when you are chang-
ing them. G
Risk of injury
Xenon bulbs carry a high voltage. You could
get an electric shock and be seriously or
even fatally injured if you touch the electri c
contacts on xenon bulbs. Therefore, neve r
remove the cover from xenon bulbs. Do not change xenon bulbs yourself, but
have them replaced at a qualified specialist
workshop which has the necessary special-
ist 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 work-
shop. Practical advice

G
Risk of accident
The windscreen will no longer be properly
wiped if the wiper blades are worn. Thi s
may prevent you from observing the traffic
conditions, thereby causing an accident.
Replace the wiper blades twice a year, ide-
ally in spring and autumn. G
Risk of accident
The wiper arms could start moving and
cause an injury if you leave the windscreen
wipers switched on.
Remove the key from the ignition lock
before replacing the wiper blades.
! Make sure you touch only the wiper arm
of the windscreen wiper to avoid damaging
the windscreen wiper blades.

pressure can briefly rise to around 5 bar.
Do not switch off the compressor during
this phase.
X Let the compressor run for five minutes.
The tyre should then have a pressure of at
least 1.8 bar.
! Do not operate the electric air pump for

5 Centre or a special collection point for old
batteries . G
Risk of injury
Mercedes-Benz recommends that, for
safety reasons, you only use batteries
which have been tested and approved for
your vehicle by Mercedes-Benz. These bat-
teries provide increased impact protectio n
to prevent vehicle occupants from suffering
acid burns should the battery be damage d
in the event of an accident .
To prevent acid burns, observe the follow-
ing safety notes when handling batteries:
R Do not lean over batteries .
R Do not place any metal objects on a bat-
tery. You could otherwise cause a short
circuit and the battery's highly flammabl e
gas mixture could ignite.
R Make sure that you do not create elec-
trostatic charge, e.g. by wearing syn-
thetic clothing or as a result of friction on
fabrics. You should not therefore pull or
slide the battery over carpets or other
synthetic materials.
R Never touch the battery first. To dis-
charge a possible electrostatic charge, step out of the vehicle first and touch the
bodywork.
R Do not wipe the battery using a cloth. Th e
battery may explode as a result of elec-
trostatic charge or through the creation
of sparks .
! Switch the engine off and remove the key
before unscrewing or disconnecting the
terminal clamps from the battery. You may
otherwise destroy electronic components
such as the alternator.
Have the starter battery checked and, if
necessary, replaced at a qualified specialist
workshop, e.g. a Mercedes-Benz Service
Centre, every two years or at least every
20,000 km.
i Mercedes-Benz recommends that you
have all work involving the battery, e.g.
removing, charging and replacing, carried
out at a qualified specialist workshop, e.g.
a Mercedes-Benz Service Centre.
Installation location of the battery Depending on its engine type, your vehicle is
equipped with a battery in the engine com-
partment or boot/luggage compartment. It islocated on the right-hand side (direction of
travel) in front of the bulkhead or on the right-
hand side in the spare wheel well.

will need to apply more pressure to brak e
and the brake pedal travel will be longer ; you may have to depress the brake peda
l
with full force
R you can no longer turn the key in the igni-

! Always disconnect the battery in the
sequence described below. Never swap the
terminal clamps. You may otherwise dam-
age the vehicle electronics.
Vehicles with the battery in the engine
compartment:
X Firmly depress the parking brake and shift
the selector lever to position Pon vehicles
with automatic transmission*.
X Switch off all electrical consumers .
X Turn the key to position 0in the ignition
lock and remove it.
X Open the bonnet.

y G
Risk of injury
Only charge the installed battery with a bat-
tery charger which has been tested and
approved by Mercedes-Benz. These battery
chargers allow the battery to be charge d
while it is still installed. Otherwise, the vehi -
cle's electronic system may be damaged.
Only charge the battery in a well-ventilate d
area. As the battery is being charged, gases
can escape and generate minor explosions.
This may 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 when still installed from a qualified
specialist workshop, e.g. a Mercedes-Ben z
Service Centre. G
Risk of injury
There is a risk of acid burns during the
charging process due to the gases which
escape from the battery. Do not lean ove r
the battery during the charging process.
! Only use battery chargers with a maxi-
mum charging voltage of 14.8 V.
X Charge the battery. Observe the notes in
the operating instructions for your battery
charger.
X Refit the charged battery.
To do this, follow the steps described in
"Removing the battery" (Y page 327) in
reverse order. G
Risk of injury
Battery acid is caustic. Avoid contact with
the skin, eyes or clothing . Practical advice
