The reversing camera is an optical aid. It
shows the area behind your vehicle in the
COMAND APS display. G
Risk of injury
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured. The reversing camera is located in the handle
strip of the boot lid/tailgate.
Example: Saloon
:
Reversing camera
View through the camera The area behind the vehicle is displayed in a
mirrored fashion, as in the rear-view mirror.
G
Risk of accident
The reversing camera is only an aid and may
display obstacles in a distorted or incorrect
manner, or may not even display them at all.
The reversing camera does not relieve you of
the responsibility to pay attention. The cam-
era cannot show objects:
R very near to the rear bumper
R below the rear bumper
R in the area immediately above the boot lid
handle/tailgate handle recess
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. This applies to the areas
behind, in front of and next to the vehicle. You
could otherwise endanger yourself and oth-
ers. G
Risk of accident
Under the following circumstances, the
reversing camera will not function, or function
in a limited manner: 162

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

loss warning system or with the tyre pressure
monitor*.
! The maximum permissible distance which
can be driven in run-flat mode depends on
the load in the vehicle. It is 80 km if the
vehicle is partially laden and 30 km if fully
laden.
The maximum permissible distance which
can be driven in run-flat mode is counted
from the moment the tyre pressure loss
warning appears in the multi-function dis-
play.
You must not exceed a maximum speed of
80 km/h. G
Risk of accident
The handling characteristics of your vehicle
deteriorate in run-flat mode, for example:
R when cornering
R when braking
R when accelerating rapidly
Adapt your driving style accordingly and avoid
sudden changes in direction and sudden
acceleration, as well as driving over obstacles
(i.e. kerbs, potholes), and driving off-road.
This is particularly the case when the vehicle
is heavily laden.
The maximum permissible distance that can
be driven in run-flat mode depends to a large
extent on the loads placed on the vehicle. It
can be shorter due to high speeds, a heavy
load, sudden acceleration and/or manoeu-
vring, the road surface condition, outside tem-
perature, etc., or further, if you drive carefully
and conservatively.
Do not continue to drive in run-flat mode if:
R you hear banging noises.
R the vehicle starts to shake.
R you see smoke and smell rubber.
R ESP ®
is intervening constantly.
R there are tears in the sidewalls of the tyre. After driving in run-flat mode, you must have
the wheel(s) checked for damage at a quali-
fied specialist workshop which has the nec-
essary specialist knowledge and tools to carry
out the work required. The faulty tyre must be
replaced in every case.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at a qualified specialist workshop.
Vehicles with MOExtended tyres*: if you
change one or all of the tyres, make sure that
you only use tyres marked MOExtended of the
specified size for the vehicle. Battery
Notes on the vehicle battery
In order for the battery to achieve the maxi-
mum possible service life, it must always be
sufficiently charged.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for a
lengthy period.
To prevent damage from corrosion, only
replace the battery with one that has a central
ventilation cover.
Consult a Mercedes-Benz Service Centre if
you wish to leave your vehicle parked up for
a long period of time. G
Risk of injury
Comply with safety precautions and take pro-
tective measures when handling batteries. Risk of explosion
Fire, naked flames and
smoking are prohibited
when handling the battery.
Avoid creating sparks. Battery

the jump-starting procedure
(Y
page 323).
Fitting the battery X
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.).
X Connect the positive terminal clamp and
secure the cover.
X Connect the negative terminal clamp.
X Connect the breather hose.
X On vehicles with the battery in the
engine compartment: put the filter box
back in place, then clip in and close the
retaining clamps.
Close the bonnet.
X Vehicles with the battery in the boot:
close the boot.
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.
X Manual transmission: engage neutral.
X Automatic transmission*: shift the trans-
mission to position P.
X Switch off all electrical consumers (e.g.
radio, blower, etc.).
X Open the bonnet (Y page 219). Jump-starting

the vehicle is being towed with the front
axle raised or if the parking brake is being
tested on a dynamometer. Otherwise,
intervention by ESP ®
