Towing and tow-starting
Important safety notes
GWarning
If you tow the vehicle, you must use a rigid
towing bar if:
R the engine will not run.
R there is a malfunction in the brake system.
R there is a malfunction in the power supply
or the vehicle's electrical system.
With the engine not running, there is no power
assistance for the brake and steering
systems. You will then need considerably
more force to steer and to brake and the
brake pedal travel will be longer. If necessary,
depress the brake pedal with maximum force.
Before towing away, make sure that the
steering can be moved and is not locked.
If you tow or tow-start another vehicle, its
weight must not exceed the maximum
permissible gross vehicle weight of your
vehicle.
It is better to have the vehicle transported
than to have it towed.
! You may only tow the vehicle a maximum
distance of 30 miles (50 km). A towing
speed of 30 mph (50 km/h) must not be
exceeded.
For towing distances over 30 miles
(50 km), the vehicle must loaded onto a
transporter.
! Only secure the tow rope or tow bar at the
towing eyes. Otherwise, the vehicle could
be damaged.
! Do not use the towing eye for recovery,
as this could damage the vehicle. If in
doubt, recover the vehicle with a crane.
! Drive slowly and smoothly when towing.
Excessive tractive power could otherwise
damage the vehicles.
! Do not tow with sling-type equipment.
This could damage the vehicle.
! When towing vehicles with KEYLESS-GO,
use the key instead of the Start/Stop
button. Otherwise, the automatic
transmission may shift to position P when
the driver's or front-passenger door are
opened, which could lead to damage to the
transmission.
! Vehicles with differential locks: make
sure that the differential locks are in
automatic mode. When towing, the
differential locks must not be switched on
by hand. This could otherwise damage the
transmission.
! Vehicles with automatic transmission
must not be started by tow-starting. This
could otherwise damage the transmission.
! Vehicles with 4MATIC must not be towed
with the front or rear axle raised. This could
otherwise damage the transmission.
If the vehicle has suffered transmission
damage, have it carried away on a transporter
or trailer.
The automatic transmission must be in
position N when the vehicle is being towed.
Make sure that the battery is connected and
charged. You will otherwise not be able to:
R turn the SmartKey to position 2 in the
ignition lock.
R shift the automatic transmission to
position N.
i Switch off the automatic locking feature
before the vehicle is towed ( Y page 79).
Otherwise, you could lock yourself out of
the vehicle when pushing or towing the
vehicle.
