Risk of accident and injury
The operating safety of your vehicle may be affected if service work is carried out incorrectly.
You could lose control of your vehicle and cause an accident. In addition, the safety systems may
no longer be able to protect you or others as they are designed to do.
Always have service work performed at a qualified specialist workshop which has 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

G
Risk of accident
The windscreen will no longer be wiped prop-
erly if the wiper blades are worn. This could
prevent you from observing the traffic condi-
tions, thereby causing an accident. Replace
the wiper blades twice a year, ideally 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.
! To avoid damaging the windscreen wiper
blades, make sure that you touch only the
wiper arm of the windscreen wiper. Removing

X Fold the wiper arm away from the wind-
screen until it engages.
X Set the wiper blade at right angles to the
wiper arm.
Vehicles with KEYLESS GO*
X Switch off the engine.

ers. The vehicle will then use very little
energy, thus conserving the battery.
i If the battery is discharged, you must use
the emergency key element to unlock the
vehicle. Charging the battery
G
Risk of injury
Only charge the installed battery using a
Mercedes-Benz approved battery charger.
Otherwise, the vehicle's electronic system
may be damaged. Only charge the battery in
a well-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 paint-
work or acid corrosion on the vehicle.
You can obtain information about battery
chargers which allow the battery to be
charged while still installed from a qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre. G
Risk of injury
There is a risk of acid burns during the charg-
ing process due to the gases which escape
from the battery. Do not lean over the battery
during the charging process.
X Use the electric parking brake to secure the
vehicle and use the DIRECT SELECT lever
to set the transmission to P.
X Switch off all electrical consumers.
X Turn the key to position 0in the ignition
lock and remove it.
X Open the bonnet.
X Check that the breather hose is fitted and
that there is a cell cap on the opposite side
of the battery.
X Remove the cover from the positive termi-
nal.
X Connect the positive clamp of the battery
charger to the positive terminal of the bat-
tery. X
Connect the negative clamp of the battery
charger to the vehicle's earth point.
X Charge the battery. Observe the notes in
the operating instructions for your battery
charger.
X Disconnect the battery charger after charg-
ing.
X Attach the positive terminal cover.
X Close the bonnet. Jump-starting
If your vehicle's battery is discharged, the
engine can be jump-started from another
vehicle or from an external battery using jump
leads.
Observe the following points:
R jump-starting may only be performed when
the engine and catalytic converter are cold.
R do not start the engine if the battery is fro-
zen. Let the battery thaw first.
R jump-starting may only be performed from
batteries with a nominal voltage of 12 V.
R only use jump leads which have a sufficient
cross-section and insulated terminal
clamps.
i Jump leads and further information about
jump-starting can be obtained from any
Mercedes-Benz Service Centre.
! Avoid repeated and lengthy starting
attempts.
Never start the vehicle using a rapid battery
charger. G
Risk of injury
There is a risk of acid burns when jump-start-
ing a vehicle due to the gases which escape
from the battery. Do not lean over the battery
while the engine is being jump-started. 384

G
Risk of explosion
Gases escaping from the battery during jump-
starting may cause minor explosions. Avoid
creating sparks. Keep naked flames away
from the battery, and do not smoke.
Comply with safety precautions and take pro-
tective measures when handling batteries.
You will find these under "Battery" in the
index. X
Make sure that the two vehicles do not
touch.
X Secure the vehicle by applying the electric
parking brake.
X Move the DIRECT SELECT lever to P.
X Switch off all electrical consumers (e.g.
radio, blower, etc.).
X Open the bonnet (Y page 292). X
Remove the cover from positive termi-
nal :.
X Connect positive terminal :on your vehi-
cle to positive terminal ;of donor battery
A using the jump lead, beginning with your
own battery.
X Start the engine of the donor vehicle and
run it at idling speed.
X Connect negative terminal =of donor bat-
tery Ato earth point ?of your vehicle
using the jump lead, connecting the jump
lead to donor battery Afirst.
X Start the engine.
X First, remove the jump lead from earth
point ?and negative terminal =, then
from positive terminal :and positive ter- minal
;, each time disconnecting from the
battery on your own vehicle first.
X Have the battery checked at a qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre. Disconnecting and removing the bat-

Points to remember
G
Risk of accident
If you have the vehicle towed, you must use a
rigid towing bar if:
R the engine is not running.
R there is a brake system malfunction.
R there is a malfunction in the power supply
or the vehicle's electrical system.
The power steering and the brake force boos-
ter do not work when the engine is not run-
ning. Greater braking force will then be
required and brake pedal travel will be longer.
If necessary, depress the brake pedal with full
force.
Before towing away, make sure that the steer-
ing can be moved and is not locked. 386
