Important safety notes
GWARNING
In order to avoid possible loss of vehicle
control, all seat, head restraint, steering
wheel and rear view mirror adjustments, as
well as fastening of seat belts, must be done
before setting the vehicle in motion.
GWARNING
Do not adjust the driver's seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never travel in a moving vehicle with the seat
backrest in an excessively reclined position as
this can be dangerous. You could slide under
the seat belt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck. This could cause serious or
fatal injuries. The seat backrest and seat belts
provide the best restraint when the wearer is
in a position that is as upright as possible and
seat belts are properly positioned on the
body.
GWARNING
Your seat belt must be adjusted so that you
can correctly fasten your seat belt.
Observe the following points:
R adjust the seat backrest until your arms are
slightly angled when holding the steering
wheel.
R adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The
position should be as far back as possible
with the driver still able to operate the
controls properly.
R adjust the head restraint so that it is as
close to the head as possible and the center
of the head restraint supports the back of
the head at eye level.
R never place hands under the seat or near
any moving parts while a seat is being
adjusted.
Failure to do so could result in an accident
and/or serious personal injury.GWARNING
The electrically adjustable seats can be
operated at any time. Therefore, do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. A child's
unsupervised access to a vehicle could result
in an accident and/or serious personal injury.
GWARNING
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children be placed in the rear seats whenever
possible. Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child. For additional
information, see "Children in the vehicle".
A child's risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.

Permissible trailer loads and drawbar
noseweights
Weight specifications
The Gross Trailer Weight (GTW) is the
combined weight of the trailer together with
the cargo and equipment loaded on the
trailer. Permissible gross weight: 7500 lb
(3402 kg).
The permissible Trailer drawbar Weight
Rating (TWR) is the maximum weight
permitted on the trailer drawbar: 600 lb
(272 kg) limit for Mercedes-Benz-approved
trailer couplings.
Loading a trailer
R When loading a trailer, please note that
neither the permissible gross trailer weight
nor the permissible Gross Vehicle Weight
Rating (GVWR) may be exceeded. The
permissible Gross Vehicle Weight Rating
(GVWR) is specified on the type plate
located on the B-pillar on the driver's side
of your vehicle.
You can find the maximum permissible
values on the type plates of your vehicle
and the trailer. Always observe the lowest
respective value when determining the
maximum weight with which you can load
the vehicle and the trailer.
R The drawbar noseweight acting on the ball
coupling has to be added to the rear axle
weight in order to prevent the permissible
Gross Axle Weight Rating (GAWR) from
being exceeded. The permissible Gross
Vehicle Weight Rating (GVWR) is specified
on the type plate located on the B-pillar on
the driver's side of your vehicle.
i Mercedes-Benz recommends loading the
trailer so that the drawbar noseweight
remains between 8% and 15% of the
permissible gross trailer weight.
i The weight of additional accessories,
passengers, and cargo reduces the
permissible trailer load and drawbar
noseweight for your vehicle.
Checking the vehicle and trailer weight
R To check that the weights of the towing
vehicle and the trailer comply with the
maximum permissible values, have the
vehicle/trailer combination (including the
driver, passengers, and cargo with a fully
laden trailer) weighed on a calibrated
weighbridge.
R Check the gross axle weight rating of the
front and rear axle, the Gross Trailer Weight
(GTW), and the drawbar noseweight.
Trailer power supply
The trailer power socket of your vehicle is
designed for connecting the 7-pin connector
supplied as part of the Mercedes-Benz-
approved trailer coupling.
i Depending on your trailer, you may need
an adapter to connect your trailer to the
vehicle.
Further information is available from any
authorized Mercedes-Benz Center.

Loading guidelines
GWARNING
Always fasten items being carried as securely
as possible. Use cargo tie-down rings and
fastening materials appropriate for the weight
and size of the load.
In an accident, during hard braking or sudden
maneuvers, loose items will be thrown around
inside the vehicle. This can cause injury to
vehicle occupants unless the items are
securely fastened in the vehicle.
To help avoid personal injury during a collision
or sudden maneuver, exercise care when
transporting cargo. Do not pile luggage or
cargo higher than the seat backrests.
The cargo compartment is the preferred place
to carry objects. Always use cargo tie-down
rings, and if so equipped, always use the cargo
net when transporting cargo.
Never drive a vehicle with the tailgate open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in
unconsciousness and death.
The gross vehicle weight (GVW) is the vehicle
weight including fuel, vehicle tool kit, spare
wheel, installed accessories, vehicle
occupants and luggage/cargo.
The gross load limit and the gross vehicle
weight rating (GVWR) for your vehicle must
never be exceeded. The gross load limit and
the GVWR are specified on the vehicle
identification plate on the B-pillar of the
driver's door ( Y page 349).
The load must also be distributed so that the
weight on each axle never exceeds the gross
axle weight rating (GAWR) for the front and
rear axles. The specifications for GVWR and
GAWR are on the vehicle identification plate
on the B-pillar of the driver's door
( Y page 349).
Further information can be found in the
"Loading the vehicle" section ( Y page 349).
The handling characteristics of a laden
vehicle are dependent on the distribution of
the load within the vehicle. For this reason,
you should observe the following notes when
transporting a load:
R position heavy loads as far forwards as
possible and as low down in the cargo
compartment as possible.
R the load must not protrude above the upper
edge of the seat backrests.
R always place the load against the rear or
front seat backrests. Make sure that the
seat backrests are securely locked into
place.
R hook in the cargo net when loading.
R always place the load behind unoccupied
seats if possible.
R secure the load with sufficiently strong and
wear-resistant tie down. pad sharp edges
for protection.

Cross bar
Points to observe before use
The maximum roof load that can be used with
additional accessories decreases by the dead
weight of the crossbars (13.7 lbs/6.2 kg).
! Note that installing the crossbar
increases the vehicle height by 50 mm
compared to the height stated in the
"Technical data" section.
The wrench and the Allen key are located with
the vehicle tool kit in the stowage space
underneath the trunk floor ( Y page 314).
i Replacement parts are available as
Mercedes-Benz accessories. Contact your
authorized Mercedes-Benz Service Center.
Installing the crossbars
GWARNING
Please follow these installation instructions
carefully. Caution should be exercised to
avoid damage to the vehicle while installing
the crossbars. Also, be careful not to injure
yourself or others while installing and
adjusting the crossbars or loading items on
them.
Each individual step of the installation
instructions, the warning notices, the general
safety precautions and the instructions for
use must be followed exactly. If the crossbars
are not mounted correctly, they and the
objects attached to them could come loose
from your vehicle and cause an accident,
thereby injuring you and other persons and/
or causing damage to property, including
damage to your vehicle.
GWARNING
Every time the crossbars are mounted, before
you set off on a journey and periodically
during longer journeys, check all the screws
on the crossbars to make sure that they are
secure, and tighten them if necessary. Repeat
these checks at regular intervals as road-
surface conditions dictate, and at least after
every 1500 miles (2500 km) of continuous
use.
Otherwise, the crossbars, mounted
accessories and the objects attached to them
could come loose from the vehicle causing an
accident, thereby injuring you and other
persons and/or causing damage to property,
including damage to your vehicle.
Do not use lubricant on the screws of the
crossbars. The screws could work loose and
the crossbars could become detached from
your vehicle, together with the objects
attached to them causing an accident,
thereby injuring you and other persons and/
or causing damage to property, including
damage to your vehicle.GWARNING
Only install the crossbars at the exact
locations designated on the roof rails. The
designated locations for the front crossbars
are between the markings engraved on the
inside of the roof rails. The designated
locations for the rear crossbars are between
the gaps on the roof rails.
Otherwise, the crossbars, mounted
accessories and the objects attached to them
could come loose from the vehicle causing an
accident, thereby injuring you and other
persons and/or causing damage to property,
including damage to your vehicle.
GWARNING
A roof load creates a greater surface area
exposed to the wind and causes the vehicle
to have a higher center of gravity, thereby
changing the vehicle's driving characteristics.
Accordingly, the additional weight on the roof
of the vehicle can have a detrimental effect
on braking, cornering and acceleration.
Never exceed the maximum permissible roof
load or the maximum permissible vehicle
278Stowage areasStowing and features

weight, even when accessories for the
crossbars (e.g. ski racks, bicycle racks, etc.)
are being used. Overloading the vehicle could
result in an accident. When calculating the
weight placed on the roof please make sure
to add the weight of the crossbars, accessory
racks and the load carried together.
Always adapt your driving style to the road,
traffic and weather conditions, and drive with
added caution when the roof is loaded.
Always drive with extreme care when the
carrier is loaded. Take into consideration that
when the carrier is loaded, the handling
characteristics are different from those when
operating the vehicle without a carrier loaded.GWARNING
Do not use accessories which have not been
approved by Mercedes-Benz for use in
conjunction with these crossbars. If non-
approved accessories are used, these
accessories and/or the objects attached to
them could come loose from the vehicle,
thereby injuring you and other persons and/
or causing damage to property, including
damage to your vehicle.
! Have a second person assist you when
installing the crossbars. Otherwise, the
vehicle could be damaged.
! Objects that are attached to crossbar
system accessories must not limit or
obstruct the movement of the sliding
sunroof. Otherwise, the tilt/sliding sunroof
could be damaged when it is raised.
