Jump-starting
291
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 290) in
reverse order.
! Do
not fit refillable batteries without elec-
trostatic protection. The electrostatic dis-
charge could otherwise cause the battery
to explode. The battery acid released could
cause damage to your vehicle.
Further information on electrostatic protec-
tion (Y page 289). G
Risk of injury
Battery acid is caustic. Avoid contact with
the skin, eyes or clothing. Reconnecting the battery
! Always reconnect the battery in the
sequence
described below. Never swap the
terminal clamps. You may otherwise dam-
age the vehicle electronics.
X Switch off all electrical consumers.
X Connect the positive terminal clamp and
secure the cover.
X Connect the negative terminal clamp.
X Connect the breather hose. Make sure that
a
cell cap is fitted between the battery and
the breather hose.
X Refit the electrostatic protection if neces-
sary ( Y page 289).
i If
the battery power supply has been inter-
rupted (e.g. if it has been reconnected), you
must carry out the following tasks:
R Set the time (Y page 125).
R Reset the sliding/tilting sunroof*
(Y page 171).
R Reset the function for folding the exterior
mirrors in/out automatically* by folding
the mirrors out once ( Y page 84). 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 must only be performed
when the engine and catalytic converter
are cold.
R Do not start the engine if the battery has
frozen. Thaw the battery out first.
R Jump-starting may only be performed from
12V batteries.
R Only use jump leads which are protected
against polarity reversal and which have a
sufficient cross-section and insulated ter-
minal clamps.
i Jump leads which are protected against
polarity reversal 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. Practical advice
