Example: multifunction lever
Vehicles
without a retarder are equipped with
3 brake stages (1 - 3).
If the ignition lock is switched to drive posi-
tion and the à indicator lamp flashes in
the instrument cluster, the multifunction
lever is not in position g.
X
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 posi-
tion 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 brak-
ing.
Observe the effective engine braking range
marked on the rev counter
(Y page 138).
At very low outside temperatures, the engine
brake has limited or no effect after the engine
has been started.
Retarder
If the à indicator lamp flashes in the
instrument cluster, the retarder's braking
power is reduced.
X
Shift down in good time.
The engine braking effect and the engine
cooling effect are increased.
Manual transmission
Important safety notes
G
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
otherwise damage the transmission, the
engine or the clutch:
R
do not drive with an engine speed that is
too high or too low.
R
only engage reverse gear with the engine
at idling speed and the vehicle station-
ary.
R
when changing gear, make sure that the
engine speed does not enter the red
overrevving range in the rev counter.
R
release the gear lever when you have fin-
ished changing gear. Do not rest your
hand or arm on the gear lever.
R
if a warning tone sounds when down-
shifting, 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 synchronisa-
