For vehicles with air suspension, check the
driving level during towing/tow-starting
and correct it if necessary. Otherwise, parts
of the vehicle or the air suspension could be
damaged.
R
Before towing, switch off Active Brake
Assist. Otherwise, Active Brake
Assist could brake the vehicle while it is
being towed. This could cause the brakes to
overheat and be damaged.
If you transport the vehicle on a low-loader, the
permissible vehicle height may be exceeded.
Pay attention to the headroom clearance of
buildings, e.g. bridges.
Before towing away, agree on a clear signal with
the towing vehicle driver. Both you and the tow-
ing vehicle driver must adapt the driving style
used to the more difficult conditions.
Information on charging the compressed-air
system using an external compressed-air
source can be found in the "Charging the
compressed-air system" section (

Information on releasing the spring-loaded park-
