3 Releasing the parking lock manually
(vehicles with automatic transmis-
sion*)
In the event of an electrical fault, it is possible
to release the selector lever lock manually to
move it out of position P, e.g. if you wish to
tow the vehicle away. 1
Selector lever cove r

X Depress the parking brake firmly.
X Press selector lever cover 1to the left and
remove it upwards . X
Press release button 2down and simul-
taneously move the selector lever out of
position P.
The selector lever can now be moved freely
until it is returned to position P. Resetting triggered NECK-PRO head
restraints
If the NECK-PRO head restraints are triggered
in an accident, you must reset the hea d
restraints on the driver's and front-passenge r
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 been 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 This work requires a lot of strength; if you
have difficulty resetting the head
restraints, have this work carried out at a
qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre. Practical advice

Jump-starting
328 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 Close the boot/luggage compartment.
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 Reset the function for folding the exterio r
mirrors in/out automatically* by folding
the mirrors out once (Y page 94). 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 must only be performed
when the engine and catalytic converte r
are cold.
R Do not start the engine if the battery ha s
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 informatio n
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 -
starting a vehicle due to the gases which
escape from the battery. Do not lean over
the battery while the engine is being jump-
started. 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 tak e
protective measures when handling batter-
ies. You will find these under “Battery” in
the index .
X Make sure that the two vehicles do not
touch.
X Depress the parking brake.
X Manual transmission: engage neutral.
X Automatic transmission*: move the
selector lever to P.
X All vehicles: switch off all electric consum-
ers . Practical advice
