Tipper with air suspension in road paver mode

(overrun mode)
In road paver mode, the road paver presses roll‐
ers on the underride guard against the tyres. This
causes the vehicle to be pushed forwards at the
speed of the road finishing machine.
Switch the level control system to road paver
mode (
page 264).
/
For most road pavers, the optimal road paver
roller position is preset. The road paver rollers
should touch the approach plate roughly in the
centre. Do not use the parking brake in overrun
mode and only perform slight adaptive braking
with the service brake.
The vehicle's level will be adjusted automatically.
If the road paver rollers do not touch the centre
of the approach plate, a different driving level can
be set before power take-off is activated
(

Notes on driving off-road

& WARNING Risk of injury due to acceler‐
ating force during off-road driving
When driving off-road on uneven surfaces,
the force of the vehicle's acceleration affects
your body from all directions.
You could, for example, be thrown from your
seat.
Always wear a seat belt when driving
#
off-road.
& WARNING Risk of fire due to flammable
materials on hot parts of the exhaust sys‐
tem
Flammable material such as leaves, grass or
twigs may ignite if they come into contact
with hot parts of the exhaust system.
When driving on unpaved roads or off-
#
road, regularly check the vehicle under‐
side.
Remove trapped plants or other flam‐
#
mable material, in particular.
If there is damage, consult a qualified
#
specialist workshop immediately.
& WARNING Risk of skidding when ABS is
deactivated
If ABS is deactivated, the wheels may lock
when braked.
As a result, the vehicle can no longer be
steered.
Always leave ABS on when driving on
#
roads and firm surfaces.
When driving off-road, substances such as dirt,
sand, mud and water or water mixed with oil may
get into the brakes. This may lead to a reduction
in braking effect or total brake failure, also as a
result of increased wear. The braking characteris‐
tics will vary depending on the material that has
got into the system. Clean the brakes after driv‐
ing off-road. If you then notice reduced braking
effect or hear grinding noises, have the brake
system checked at a qualified specialist work‐
shop. Adjust your driving style to the changed
braking characteristics.
Driving off-road demands special driving skills
and concentration. Furthermore, the driver must
take special care when driving off-road and
before driving on-road again. Please make sure
you read this section thoroughly before attempt‐
ing to drive the vehicle off-road. You will then
understand the particular advantages your vehi‐
cle offers to enable you to always reach your des‐
tination safely. Mercedes-Benz recommends that
you practice driving off-road in less demanding
terrain. When driving on difficult terrain for the
