Starting-off aid
! The starting-off aid is only intended for
short-term use for spinning wheels on snow
and ice-covered roads. If you activate the
starting-off aid, the rear axle load increases.
Using the starting-off aid for longer periods
could damage the rear axle. When doing so, if
the tyre load-bearing capacity is exceeded for
longer periods, the tyres can explode.
The starting-off aid can also be installed with a
speed limiter or a time limit (switch-on inter-
lock). If the starting-off aid does not have a time
limit, then make sure that the starting-off aid is
only activated for a short period.
R
The starting-off aid with speed limiter auto-
matically switches off at a vehicle speed of
above 30 km/h. The starting-off aid can only
be activated again when the speed falls below
30 km/h.
R
The starting-off aid with switch-on interlock
switches off automatically after 90 seconds.
After 50 seconds, the starting-off aid with
switch-on interlock can be reactivated.
R
The starting-off aid without switch-on inter-
lock is deactivated automatically after
120 seconds and can be reactivated immedi-
ately thereafter.
X To activate the starting-off aid: press the
å
button.
As long as the starting-off aid is activated, the
å
indicator lamp in the status area of the
on-board computer lights up yellow.
i If the starting-off aid does not have a time
limit, deactivate the starting-off aid manually
after a short period of time.
X
To deactivate the starting-off aid man-
ually: press the
¤
button on the instru-
ment panel or the
T
button on the control
panel of the level control (
Y
page 298).
Leading/trailing axle
H
Environmental note
When the leading/trailing axle is raised, roll
resistance is reduced. This reduces tyre wear
and fuel consumption.
The leading/trailing axle is lowered just before
the permissible axle load is reached. Observe
the notes in the "Axle loads and wheel loads"
section (
Y
page 266) and those on the vehicle
identification plate (
Y
page 417).
On vehicles for the transportation of bulk cargo,
weight can only be taken off the trailing axle and
it cannot be raised.
Vehicles with a steerable trailing axle
(
Y
page 301): when you raise the additional
axle, the wheels move into the straight-ahead
position. When you lower the additional axle, the
wheels again steer actively.
X Switch the ignition lock to the drive position.
X
If the reservoir pressure in the compressed-
air system is too low, leave the engine run-
ning.
X If the vehicle is empty or only partially laden,
raise the leading/trailing axle before pulling
away.
X Vehicles with a rear loading crane: observe
the information in the manufacturer's oper-
ating instructions before raising the leading/
trailing axle.
