restraints
If the NECK-PRO head restraints are triggered
in an accident, you must reset the head
restraints on the driver's and front-passenger
seats. Otherwise, the additional protection
will not be available in the event of another
rear-end collision. You can recognise when
head restraints have been triggered by the
fact that they have moved forwards and can
no longer be adjusted.
Mercedes-Benz recommends that you have
NECK-PRO head restraints checked at a quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre, following a rear-end
collision.
i If you have problems resetting the head
restraints, have this work carried out at a
qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre. Practical advice

stances. For this reason, keep batteries
away from children.
If a battery is swallowed, consult a doctor
immediately. H
Environmental note

hold rubbish. They contain highly toxic sub-
stances.

Jump-starting
333
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 332) 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 331). 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 331).
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 135).
R Reset the sliding/tilting sunroof*
(Y page 182).
R Reset the function for folding the exterior
mirrors in/out automatically* by folding
the mirrors out once (Y page 91). Jump-starting
Jump-starting your vehicle
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 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
