The field of vision and other functions of the rear
view camera may be restricted due to additional
accessories on the rear of the vehicle (e.g.
license plate holder, bicycle rack).
For technical reasons, leaving the standard
height can result in inaccuracies in the guide
lines on vehicles with aheight-adjustable chas-
sis.
iThe rear view camera is protected from rain-
drops and dust by means of aflap. When the
rear view camera is activated, this flap opens.
The flap closes againw hen:
Ryou have finished the maneuvering process
Ryou switch off the engine
Ryou open the trunk
Observe the notes on cleaning (
Ypage 240).
For technical reasons, the flap may remain
open briefly after the rear view camera has
been deactivated.
Activating/deactivating the rear view camera
XTo activate: make sure that the SmartKey is
in position 2in the ignition lock.
XMake sure that the Activation byRgearfunction is selected in the multimedia system;
see the Digital Operator's Manual.

The rear view camera flap opens. The multi-
media system shows the area behind the vehi-
cle with guide lines. The image from the rear view camera is avail-
able throughout the maneuvering process.
To deactivate: the rear view camera deacti-
vates if you shift the transmission to Por after
driving forwards ashort distance.
Displays in the multimedia system
The rear view camera may show adistorted view
of obstacles, show them incorrectly or not at all.
The rear view camera does not show objects in
the following positions:
Rvery close to the rear bumper
Runder the rear bumper
Rin close range above the handle on the trunk

MOExtended tires (tires with run-flat
properties)
General notes
With MOExtended tires (tires with run flat char-
acteristics), you can continue to drive you rvehi-
cle even if there is atotal loss of pressure in one
or more tires. The affected tire must not show
any clearl yvisible damage.
You can recognize MOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You wil lfind this marking
next to the tire size designation, the load-bear-
ing capacity and the speed index (
Ypage 269).
MOExtended tires may only be used in conjunc-
tion with an active tire pressure loss warning
system or with an active tire pressure monitor.
If ap ressure loss warning message appears
in the multifunction display:
Robserve the instructions in the display mes-
sages (Ypage 196).
Rcheck the tire for damage.
Rif driving on, observe the following notes.
The driving distance possible in run-flat mode is
approximately 50 miles (80 km) when the vehi-
cle is partially laden and approximately 19 miles
(30 km) when the vehicle is full yladen. In addition to the vehicle load
,the driving dis-
tance possible depends upon:
Rvehicle speed
Rroad condition
Routsid etemperature
The driving distance possible in run-flat mode
may be reduced by extreme driving conditions
or maneuvers, or it can be increased through a
moderate style of driving.
The driving distance possible in run-flat mode is
counted from the moment the tire pressure loss
warning appears in the multifunction display.
You must not exceed amaximum speed of
50 mph (80 km/h).
When replacing one or all tires, please observe
the following specifications for you rvehicle's
tires:
Rsize
Rtype and
Rthe "MOExtended" mark
If at ire has gone flat and cannot be replaced
with aMOExtended tire, astandard tire may be
used as atemporary measure. Make sure that
you use the proper size and type (summe ror
winter tire).
Vehiclese quipped with MOExtended tires are
not equipped with aTIREFIT kit at the factory. It
is therefore recommended that you additionally
equi pyourvehicle with aTIREFIT kit if y
ou mount
tires that do not feature run-flat properties, e.g.
winter tires. ATIREFIT kit is available, for exam-
ple, from aqualifieds pecialist workshop.
Important safety notes
GWARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when corner-
ing, accelerating quickly and when braking.
There is arisk of an accident.
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneuvers,
and driving over obstacle s(curbs, potholes,
off-road). This applies in particular to aladen
vehicle.
Stop driving in emergency mode if:
Ryou hear banging noises.
Rthe vehicle starts to shake.
