Towing In Raised Position - Mercedes-Benz 963 2022 Series Manual

Towing in raised position

Important safety information
Note
Do not switch the electronic ignition lock to the drive
position when the front axle is raised.
Otherwise the automatic ASR function may cause
uncontrolled braking of the rear wheels while the
vehicle is being towed. This can cause the vehicle to
lose lateral stability and break away.
i
If possible, tow the vehicle empty.
i
Vehicles with air suspension: When the vehicle is
being lowered, ensure that the air bellows, which
may have lifted out, unroll correctly and that the
pistons are threaded into the guides.

Vehicles involved in an accident
• In vehicles with hydraulic auxiliary drive: Tow the
vehicle raised at the front axle if the hydraulic
auxiliary drive is leaky.
• Before raising the vehicle, check the connections
between the frame sections and between the frame
and the axles for damage and tight seating.
• If the air bellows on the rolling axle are defective,
ensure sufficient clearance and tow at a max. of
10 km/h.
• Fold up or detach the underride guard if necessary.
Semitrailer tractors with semitrailer
• Make sure there is sufficient clearance between the
semitrailer tractor and the semitrailer, particularly
when cornering and when starting to drive up steep
slopes.
• Attach the support fixture so that lines, cables, hoses
and other detachable parts are not damaged.
• Install warning lamps on the vehicle.
• Switch off ASR (Anti-Slip Control), Stability Control
Assist/ESP® (Electronic Stability Program) and ABA
(Active Brake Assist), see chapter "Safety systems".
• Remove the propeller shaft to the rolling axle.
• When towing entire combinations, route an ABS
cable from the towing vehicle and connect to the
trailer/semitrailer (5-pin or 7-pin).
• Set the air suspension to a height at which there is
adequate clearance between the wheels and vehicle
components, and between vehicle components and
the road surface.
