i All vehicles (apart from AMG vehi-
cles): Automatic engine switch-off can
take place a maximum of four times con-
secutively (initial stop then repeated three
times). The ¤symbol is shown in yellow
in the multifunction display after the engine
has been started automatically for the
fourth time. The automatic engine stop is
available again once when the ¤symbol
is shown in green in the multifunction dis-
play.

DrivingDriving and parking

Never use the brake pedal as a footrest. Do
not simultaneously depress both the brake
pedal and the accelerator pedal while driving. G
WARNING
You could lose control of the vehicle/trailer
combination if it begins to swerve. The vehi-
cle/trailer combination could even overturn.
There is a risk of an accident.
On no account should you attempt to
straighten out the vehicle/trailer combina-
tion by increasing speed. Decrease your
speed and do not countersteer. Brake if nec-
essary. G
WARNING
If you exceed the permissible noseweight
while carrying a load, the carrier system could
detach from the vehicle and fall on the road.
There is a risk of an accident and injury.
Always maintain the permissible noseweight
when carrying loads. G
WARNING
If the ball coupling is not correctly engaged, it
could detach while driving and fall on the road.
There is a risk of an accident and injury.
Engage the ball coupling as described. G
WARNING
If the ball coupling is not correctly engaged,
the trailer can detach. There is a risk of an
accident.
Always engage the ball coupling as described.
! Depressing the brake pedal constantly
results in excessive and premature wearto
the brake pads.
You can use carrier systems, e.g .bicycle
racks or load-bearing implements, on the ball
coupling. The maximum noseweight of
75 kg applies when using carrier systems on
the ball coupling.
When reversing the vehicle towards the
trailer, make sure there is nobody between
the trailer and the vehicle. Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
Make sure that the followin gvalues are not
exceeded:
R the permissible trailer drawbar noseweight
R the permissible trailer load
R the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weigh tofboth the towing vehicle and the
trailer
You will find the applicable permissible val-
ues, which must not be exceeded, in the vehi-
cle documents.
You will find the values approved by the man-
ufacturer on the vehicle identification plates
and those for the towing vehicle in the "Tech-
nical data" section (Y page 448).
When towing a trailer, your vehicle's handling
characteristics will be different in comparison
to when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R has a larger turning circle
This could impair the handling characteris-
tics. Adapt your style of driving accordingly.
Maintain a safe distance. Drive carefully.
When towing a trailer, always adjust your
speed to the current road and weather con-
ditions. Do not exceed the maximum permis-
sible speed for your vehicle/trailer combina-
tion. Towing

R
Maintain a greater distance from the vehi-
cle in front than when driving without a
trailer.
R Avoid braking abruptly. If possible, brake
gently at first to allow the trailer to run on.
Then, increase the braking force rapidly.
R The values given for gradient-climbing
capabilities from a standstill refer to sea
level. When driving in mountainous areas,
note that the power output of the engine,
and consequently the vehicle's gradient-
climbing capability, decrease with increas-
ing altitude. Folding out the ball coupling
G
WARNING
If the ball coupling is not correctly engaged,
the trailer can detach. There is a risk of an
accident.
Always engage the ball coupling as described. G
WARNING
If you release the ball coupling or it does not
engage correctly when folding in, it will swing
out. Within pivoting range of the ball coupling,
there is an increased risk of an accident and
injury.
Only release the ball coupling if the pivoting
range is unobstructed. Always make sure that
the ball coupling engages when folding in. G
WARNING
Vehicles with HYBRID: ensure that you read
the "HYBRID" supplement. You may otherwise
fail to recognise dangers. Saloon
