Towing and tow-starting
Important safety notes
GWARNING
The rear axle locks when:
Rthe engine is not running
Rthe engine stalls while the vehicle is being
towed
Rthere is a malfunction in the power supply
or the vehicle's electrical system
There is a risk of an accident.
In the event of a breakdown, you should
always have the vehicle transported.
GWARNING
If the brake system or power steering is mal-
functioning and your vehicle is then towed
away, significantly more effort may be
required to steer and brake than is normally
required. There is a risk of an accident.
In such cases, use a tow bar. Before towing,
make sure that the steering moves freely.
GWARNING
When towing or tow-starting another vehicle
and its weight is greater than the permissible
gross weight of your vehicle, the:
Rthe towing eye could detach itself
Rthe vehicle/trailer combination could roll-
over.
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 (
Ypage 285).
!Use the SmartKey instead of the Start/Stop
button when towing the vehicle.
Start the engine and keep it running. The
SmartKey is in position 2in the ignition lock.
Set the transmission to iusing the E-
SELECT selector lever. Make sure that you
then leave the SmartKey in position 2.Check the transmission position in the instru-
ment cluster.
!Make sure that the electric parking brake is
released. If the electric parking brake is faulty,
visit a qualified specialist workshop.
!Secure the tow rope or tow bar to the towing
eye only. Otherwise, the vehicle could
become damaged.
!When Active Brake Assist, Distance Pilot
DISTR ONIC 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:
Rwhen towing the vehicle
Rin the car wash
!Do not use the towing eyes for recovery pur-
poses as 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.
!Shift the automatic transmission to position
i and do not open the driver's or front-
passenger door when towing the vehicle
away. Otherwise, the automatic transmission
may shift to position jwhich can cause
damage to both vehicles.
!Do not tow with sling-type equipment. This
could damage the vehicle.
!The vehicle can be towed a maximum of
30 miles (50km). The towing speed of 30 mph
(50 km/h) must not be exceeded.
If the vehicle has to be towed more than
30 miles (50km), the entire vehicle must be
raised and transported.
!Observe the transmission fluid temperature
(AMG menu) in the on-board computer when
towing. The transmission fluid temperature
must not exceed 250 ‡ (
120 †). If this
occurs, you must stop towing immediately.
!Tow-starting the vehicle is not permitted.
The transmission may otherwise be damaged.
