Towing away and tow-starting
Important safety notes
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 321).
!
When Active Brake Assist, Distance Pilot
DISTRONIC or the HOLD function are activa-
ted, the vehicle brakes automatically in cer-
tain 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
!
Only secure the tow rope or towing bar to
the towing eyes. The vehicle may otherwise
be damaged.
!
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 makes other road users
aware that a vehicle is being towed.
R
only secure the tow rope to the towing eye.
R
observe the brake lamps of the towing vehi-
cle while driving. Always maintain a dis-
tance 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 towing eye for recovery, this
could damage the vehicle. If in doubt, recover
the vehicle with a crane.
!
When towing, pull away slowly and
smoothly. If the tractive power is too high, the
vehicles could be damaged.
!
To tow vehicles with KEYLESS-GO, use the
key instead of the Start/Stop button. The
automatic transmission may otherwise
switch to position P when you open the driv-
er's or front-passenger door which could
damage the transmission.
!
Make sure that the electric parking brake is
released. If the electric parking brake is faulty,
visit a qualified specialist workshop.
!
You may tow the vehicle for a maximum of
50km. A towing speed of 50 km/h must not
be exceeded.
