trian protection) after triggering
i The active bonnet is available for all mod-
els except the E 63 AMG. The bonnet is raised at the back by approx-
imately 50 mm when active bonnet :is trig-
gered. Covers ;are then no longer on hous-
ing =.
You can reset a triggered bonnet yourself.
! Do not try to press down the raised bon-
net at the back. Otherwise, the bonnet
could be damaged.
You can still continue driving with the active
bonnet triggered and have this reset at a
qualified specialist workshop. If you pull the
release lever of the bonnet, you must reset
the bonnet before you continue driving. Resetting
G
Risk of accident
If you pull the release lever of the bonnet and
do not reset the bonnet, it is not locked at the front when you close it. The bonnet may then
open when driving and block your view. If you
pull the release lever of the bonnet, you must
reset the bonnet before you continue driving. G
Risk of injury
There is a risk of injury if the bonnet is open,
even if the engine is not running.
Some engine components can become very
hot.
To avoid the risk of burns, only touch those
components described in the Owner’s Manual
and observe the relevant safety notes.
X Open the bonnet (Y page 219). Example: Saloon
X
Swing the bonnet up in centre Awith both
hands, until the covers of both bonnet
actuators ;no longer move.
Significant resistance can be felt when the
covers are pressed back down.
X Release bonnet :.
X Check whether bonnet actuator covers ;
lie flat against housing =(arrow).
X If bonnet actuator covers ; ;lie flat
against the housing: close bonnet:
(Y page 219).

Bonnet actuator covers ;should now lie
flat against housing =(arrow).
X Close bonnet :(Ypage 219).
If bonnet :cannot be closed or the L
symbol appears in the multi-function display,
repeat the steps again. G
Risk of accident
If the bonnet can still not be engaged properly
or the Lsymbol appears in the multi-func-
tion display, do not continue driving. Other-
wise, the bonnet may open when driving and
block your view. Consult a qualified specialist
workshop. Otherwise, you may cause an acci-
dent and injure yourself and others. Resetting triggered NECK-PRO head
restraints
If the NECK-PRO head restraints are triggered
in an accident, you must reset the head
restraints on the driver's and the front-pas-
senger's seats. Otherwise, the additional pro-
tection 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 col-
lision.
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. Example: Saloon
X
Tilt the top of the head restraint cushion
forwards in the direction of arrow :.
X Push the head restraint cushion down in
the direction of arrow ;as far as it will go.
X Push the head restraint cushion firmly
backwards in the direction of arrow =until
it engages.
X Repeat this procedure for the second head
restraint. Replacing batteries (key and remote
control)
Notes
It is advisable to have the batteries replaced
at a qualified specialist workshop, e.g. at a
Mercedes-Benz Service Centre. G
Risk of poisoning
Batteries contain toxic and caustic substan-
ces. For this reason, keep batteries away from
children.
If a battery is swallowed, consult a doctor
immediately. H
Environmental note
Do not dispose of batteries with the house-
hold rubbish. They contain highly toxic sub-
stances.
Take discharged batteries to a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre, or to a special collection point
for old batteries. Replacing batteries (key and remote control)

Windscreen wiper blades
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.
To remove X
Remove the key from the ignition lock or
turn the key to position 0(KEYLESS GO).
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. X
Remove the wiper blade from the retainer
on the wiper arm in the direction of the
arrow.
Fitting !
The two wiper blades are different
lengths. If you swap the wiper blades they
may scratch the windscreen. Make sure
that the longer wiper blade is fitted on the
driver's side.
X Compare the lengths of the two new wiper
blades.
X Slide the longer of the two new wiper
blades into the retainer on the wiper arm
on the driver's side in the opposite direc-
tion to the arrow.
X Repeat the same procedure on the front-
passenger's side with the shorter of the two
new wiper blades. 308

G
Risk of injury
Battery acid is caustic. Avoid contact with the
skin, eyes or clothing.
Charging the battery G
Risk of injury
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 paintwork or acid cor-
rosion 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.
! Only charge the installed battery with a
battery charger which has been tested and
approved by Mercedes-Benz. These battery
chargers allow the battery to be charged
while still installed.
! Only use battery chargers with a maxi-
mum charging voltage of 14.8 V.
! Only charge the battery using the jump-
start connection point.
X Vehicles with the battery in the engine
compartment: open the bonnet.
X Vehicles with the battery in the boot:
open the boot.
X Connect the battery charger by its positive
terminal and earth point in the same order
as when connecting the donor battery in 322

Install the battery. To do this, follow the
steps described in "Removing the battery"
(Y page 322) in reverse order.
X Reconnect the battery (Y page 323).Reconnecting the battery
! Always connect the battery in the order
described below. Never swap the terminal
clamps. Otherwise, you may damage the
vehicle electronics.
X Switch off all electrical consumers (e.g.
radio, blower, etc.).

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 ( Ypage 132)
R reset the function for folding the exterior
mirrors in/out automatically* by folding
the mirrors out once ( Ypage 87) 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
you may only jump-start 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.
Do not use a rapid-charging device to start
the engine. 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. 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 Depress the parking brake firmly.
