Always attach the bicycle rack correctly by
clamping onto the ball head and, if possible,
to the guide pin on the ball coupling as well.
R To transport four bicycles, always use bicy-
cle racks with additional support on the ball
coupling's guide pin.
R Use only bicycle racks approved by
Mercedes-Benz.
R Always comply with the bicycle rack's oper-
ating manual.
! Using unsuitable bicycle racks or using
them incorrectly can cause damage to and
fractures in the trailer tow hitch.
Use only bicycle racks approved by
Mercedes-Benz. Bicycle racks cause your vehicle's driving char-
acteristics to change. The vehicle
R is heavier
R is restricted in its acceleration and gradient-
climbing capability
R has an increased braking distance
This can impair the vehicle's handling charac-
teristics. Adapt your driving style accordingly.
Maintain a safe distance and drive carefully.
When using bicycle racks, set the tyre pressure on the rear axle of the vehicle for the maximum
load. Further information on tyre pressure can
be found on the tyre pressure table
(Y page 359). Loading instructions
The greater the distance between the load's centre of gravity and the ball head, the higher the load exerted on the trailer tow hitch.
Therefore, observe the following notes:
R Attach heavy bicycles as close as possible to the vehicle.
R Always distribute the load on the bicycle rack as symmetrically as possible to the vehicle longi-
tudinal axis.
Before loading the bicycle rack, Mercedes-Benz advises you to remove all add-on parts from the
bicycles, e.g. bicycle baskets, child seats or batteries. This will allow you to improve the aerody-
namic resistance and the bicycle rack's centre of gravity.
Always secure bicycles against slipping and check that they are firmly seated at regular intervals.
Do not use tarpaulins or other covers. This could impair the driving characteristics and rear visibility. The aerodynamic resistance would also rise, and so would the load exerted on the trailer tow hitchas a result. 226

Cleaning the display !
For cleaning, do not use any of the following:
R alcohol-based thinner or petrol
R abrasive cleaning agents
R commercially-available household cleaning
agents
These may damage the display surface. Do
not put pressure on the display surface when cleaning. This could lead to irreparable dam-

is switched off and has cooled down.
X Clean the display surface using a commer-
cially available microfibre cloth and TFT/LCD
display cleaner.
X Dry the display surface using a dry microfibre
cloth. Cleaning the plastic trim G
WARNING
Care products and cleaning agents containing solvents can cause surfaces in the cockpit to
become porous. This could result in plastic
parts breaking away when the airbags are
deployed. There is a danger of injury.
Do not use care products and cleaning agents containing solvents to clean the cockpit.
! Never attach the following to plastic surfa-
ces:
R stickers
R films
R perfume oil container or similar
You could otherwise damage the plastic.
! Do not allow cosmetics, insect repellent or
sunscreen to come in contact with the plastic trim. This maintains the high-quality look of
the surfaces.
X Wipe the plastic trim with a damp, lint-free
cloth, e.g. a microfibre cloth.
X Heavy soiling: use care and cleaning prod-
ucts recommended and approved by
Mercedes-Benz.
The surface may change colour temporarily.
Wait until the surface is dry again.
Cleaning the steering wheel and selec-
tor lever X
Thoroughly wipe with a damp cloth or use
leather care agents that have been recom-
mended and approved by Mercedes-Benz.
Cleaning wood trim and trim elements !
Do not use solvent-based cleaning agents
such as tar remover, wheel cleaners, polishes
or waxes. There is otherwise a risk of damag- ing the surface. 336

When your vehicle is towed away or towed
started, you may require considerably more
effort to steer and brake. There is a risk of an
accident.
In such cases use a rigid towing bar. Before
being towed away or tow started, make sure
the steering moves freely. G
WARNING
If the steering wheel lock is engaged, the vehi- cle can no longer be steered. There is a risk of
an accident.
Always switch on the ignition when towing
with a tow rope or a towing bar. G
WARNING
When towing or tow-starting another vehicle
and its weight is greater than the permissible gross weight of your vehicle, the:
R towing eye may be torn off
R car/trailer combination may swerve or
even overturn
There is a risk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the per- missible gross weight of your vehicle.
Details on the permissible gross vehicle weight
of your vehicle can be found on the vehicle iden-
tification plate (Y page 372).
! When Active Brake Assist, Distance Pilot
DISTRONIC or the HOLD function is activated, the vehicle brakes automatically in certain
situations.
To avoid damage to the vehicle, deactivate
these systems in the following or similar sit-
uations:
R when towing away
R in a car wash
! Make sure that the electric parking brake is
released. If the electric parking brake is faulty, visit a qualified specialist workshop.
! Only secure the tow cable or tow bar to the
towing eyes or, if available, to the trailer tow
hitch. You could otherwise damage the vehi-
cle. !
Observe the following points when towing
with a tow rope:
R Secure the tow rope on the same side on
both vehicles.
R Make sure that the tow rope is not longer
than legally permitted. Mark the tow rope in
the middle, e.g. with a white cloth
(30 x 30 cm). This will make other road
users aware that a vehicle is being towed.
R Only secure the tow cable to the towing
eyes or, if available, to the trailer tow hitch.
R Observe the brake lamps of the towing
vehicle while driving. Always maintain a dis-
tance a distance so that the tow rope does not sag.
R Do not use steel cables or chains to tow
your vehicle. You could otherwise damage
the vehicle.
! Do not use the trailer tow hitch for recovery
or towing. Do not use the towing eye for
recovery. This could damage the vehicle. If in
doubt, have the vehicle recovered using a
crane.
! When towing, pull away slowly and
smoothly. If the tractive power is too high, the
vehicles could be damaged.
! Shift the automatic transmission to
Nand
do not open the driver's or front passenger's
door during towing. The automatic transmis-
sion may otherwise shift to position P, which
could damage the transmission.
! You may tow the vehicle for a maximum of
50km. A towing speed of 50 km/h must not
be exceeded.
For towing distances over 50 km, the entire
vehicle must be lifted up and transported.
Observe the legal requirements in each individ-
ual country when towing.
It is better to have the vehicle transported than
to have it towed.
If the vehicle has suffered transmission damage, have it transported on a transporter or trailer.
The automatic transmission must be in position
N when the vehicle is being towed. If the auto-
matic transmission cannot be shifted to position
N, have the vehicle transported on a transporter
or trailer. Towing away and tow-starting

Deactivate the automatic locking feature before towing the vehicle (Y page 89). You could oth-
erwise be locked out when pushing or towing
the vehicle.
