ing a load.
Observe the following notes on securing loads: R Secure the load using the cargo tie-down
rings.
R Distribute the load on the cargo tie-down
rings evenly.
R Do not use elastic straps or nets to secure a
load, as these are only intended as an anti-slip protection for light loads. R
Do not route tie-downs across sharp edges or
corners.
R Pad sharp edges for protection. There are four cargo tie-down rings
0043in the
cargo compartment.

Cargo compartment cover
Important safety notes G
WARNING
On its own, the cargo compartment cover
cannot secure or restrain heavy objects,
items of luggage and heavy loads. You could
be hit by an unsecured load during sudden
changes in direction, braking or in the event of an accident. There is an increased risk of
injury or even fatal injury.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping over, e.g. by
using tie downs, even if you are using the
cargo compartment cover.
! When loading the vehicle, make sure that
you do not stack the load in the cargo com-
partment higher than the lower edge of the
side windows. Do not place heavy objects on top of the cargo compartment cover.
The cargo compartment cover may be installed
behind the 2nd or 3rd row of seats.

Roof carrier
Important safety notes G
WARNING
When you load the roof, the center of gravity
of the vehicle rises and the usual driving char- acteristics, as well as steering and braking,
change. The vehicle tilts more severely when
cornering and may react more sluggishly to
steering input.
If you exceed the maximum roof load, the
driving characteristics, as well as the steering
and braking, will be greatly impaired. There is a risk of an accident.
Adjust your driving style and never exceed the
maximum roof load.
! Mercedes-Benz recommends that you only
use roof carriers that have been tested and
approved for Mercedes-Benz vehicles. This
helps to prevent damage to the vehicle.
Position the load on the roof carrier in such a way that the vehicle will not sustain damage
even when it is in motion.
Depending on the vehicle equipment, ensure
that when the roof carrier is installed you can:
R raise the sliding sunroof fully
R open the panorama roof with power tilt/
sliding panel fully
R open the tailgate fully
You will find information on the maximum roof
load in the "Technical data" section
(Y page 389).
An incorrectly secured roof carrier or roof load
may become detached from the vehicle. You
must therefore ensure that you observe the roof
carrier manufacturer's installation instructions. Attaching the roof carrier X
Secure the roof carrier to roof rails 0043. In
doing so, observe the manufacturer's instal-
lation instructions. Features
Cup holder
Important safety notes G
WARNING
If you transport objects in the vehicle interior and these are not adequately secured, they
could slip or be flung around and thereby
strike vehicle occupants. In addition, cup
holders, open stowage spaces and mobile
phone brackets may not always be able to
hold the objects placed in them in the event of an accident. There is a risk of injury, particu-
larly in the event of sharp braking or sudden
changes of direction.
R Always stow objects in such a way that they
cannot be tossed about in these or similar
situations.
R Always make sure that objects do not pro-
trude out of the stowage spaces, luggage
nets or stowage nets.
R Ensure that closable stowage spaces are
shut before beginning your journey.
R Always stow and secure heavy, hard, poin-
ted, sharp-edged, fragile or large objects in
the cargo compartment.

properties)
General notes With MOExtended tires (tires with run flat char-
acteristics), you can continue to drive your vehi- cle even if there is a total loss of pressure in one
or more tires. The affected tire must not show
any clearly visible damage.
You can recognize an MOExtended tire by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking
next to the tire size designation, the load-bear-
ing capacity and the speed index (Y page 367).
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 a pressure loss warning message appears in the multifunction display:
R observe the instructions in the display mes-
sages (Y page 268).
R check the tire for damage
R if 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 18 miles
(30 km) when the vehicle is fully laden.
In addition to the vehicle load, the driving dis-
tance possible depends upon:
R Vehicle speed
R Road condition
R Outside temperature
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 a maximum permissible
speed of 50 mph (80 km/h).
i When replacing one or all tires, please
observe the following specifications for your
vehicle's tires:
