wards, e.g. when braking suddenly or in the
event of an accident.
R The vehicle occupant would thereby be
pushed into the seat belt by the rear bench
seat/rear seat or by the seat backrest. The
seat belt can no longer offer the intended
level of protection and could even cause
injuries.
R Objects or loads in the trunk/cargo com-
partment cannot be restrained by the seat
backrest.
There is an increased risk of injury.
Before every trip, make sure that the seat
backrests and the rear bench seat/rear seat
are engaged.
Make sure that the seat backrest and the seat
cushion are correctly engaged in position. To do so, pull firmly on the seat backrest.
! Release and fold the seat cushion upwards
before folding the rear bench seat forward.
Otherwise, the backrests may be damaged.
When the backrest is folded forwards, the
front seats cannot be moved to their rearmost position. Otherwise, the front seats and the
rear bench seat could be damaged.
! The backrest is heavy. Therefore, take care
when folding it down. Make sure that the head restraints are pushed all the way in so that the
backrests and seat cushions are not dam-
aged.
Observe the loading guidelines (Y page 295).
The left-hand and right-hand backrests in the
second row of seats can be folded forward sep-
arately to increase the cargo compartment
capacity.
On vehicles with a third row of seats, you must
fold down the third row of seats beforehand
(Y page 101) to obtain maximum cargo com-
partment enlargement. Folding the rear bench seat forward If the driver's or front-passenger seat is set for a
larger person, it may not be possible to fold the
rear bench seat forward. In this case, move the front seats as far forward as possible.

Cargo tie-down rings G
WARNING
The Top Tether anchorages cannot secure a

anchorages, the Top Tether anchorages could be pulled out during braking, abrupt changes
in direction or in the event of an accident. The load could slip, tip over or be flung around and
thereby hit vehicle occupants. There is a risk
of injury.
Only use the cargo tie down rings when secur-
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.
Bag hook G
WARNING
The bag hooks cannot restrain heavy objects
or items of luggage. Objects or items of lug-
gage could be flung around and thereby hit
vehicle occupants when braking or abruptly
changing directions. There is a risk of injury.
Only hang light objects on the bag hooks.
Never hang hard, sharp-edged or fragile
objects on the bag hooks.
! The bag hook can bear a maximum load of
6.6lbs (3kg) and should not be used to secure
a load. There is a bag hook in the cargo compartment
on the right-hand side.

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.
