ment with two brake levels (1 - 2).
If the ignition lock is switched to drive position
and the à indicator lamp flashes in the
instrument cluster, the multifunction lever is not
in position g.

To switch on: pull the multifunction lever to
the desired brake level.
The à indicator lamp in the instrument
cluster lights up.
The braking effect of the continuous brake is
lowest in position 1 and highest in position
5.
X
To switch off: push the multifunction lever to
position g.
The à indicator lamp in the instrument
cluster goes out.
When ABS (Anti-lock Braking System) inter-
venes, the continuous brake is switched off. The
à indicator lamp in the instrument cluster
remains on.
Engine brake
The effectiveness of the engine brake depends
on the engine speed. A high engine speed
results in more effective engine braking.
Observe the effective engine braking range
marked on the rev counter (
At very low outside temperatures, the engine
brake has limited or no effect after the engine
has been started.

Manual transmission
Retarder
If the à indicator lamp flashes in the instru-
ment cluster, the retarder's braking power is
reduced.
X
Shift down in good time.
The engine braking effect and the engine cool-
ing effect are increased.

Important safety notes

WARNING
If there is a loss of pressure or insufficient
reservoir pressure in the transmission/clutch
circuit, you can no longer shift gears. There is
a risk of an accident.
Do not pull away, or stop the vehicle as soon
as possible, paying attention to road and traf-
fic conditions. Secure the vehicle against roll-
ing away, e.g. with the parking brake. Have
the compressed-air system repaired at a
qualified specialist workshop.
!
Observe the following notes. You could oth-
erwise damage the transmission, the engine
or the clutch:
do not drive with an engine speed that is
R
too high or too low.
only engage reverse gear with the engine at
R
idling speed and the vehicle stationary.
when changing gear, make sure that the
R
engine speed does not enter the red over-
revving range in the rev counter.
release the gear lever when you have fin-
R
ished changing gear. Do not rest your hand
or arm on the gear lever.
if a warning tone sounds when downshift-
R
ing, the maximum permissible engine
speed has been exceeded. Shift to a higher
gear, not a lower gear. The power-assisted
gearshift is deactivated to protect the
transmission synchronisation. As a result,
more force is required when shifting gear.
The engine has delayed throttle response if:
the vehicle is stationary
R
the engine is running
R
the transmission is in neutral.
