Safety inspections
Checking the reservoir pressure in the
compressed-air brake system
&
WARNING Risk of accident through leaks
in the compressed-air brake system
It is not possible to brake the vehicle if the
compressed-air brake system has a leak or if
there is insufficient reservoir pressure.
#
Do not pull away until the required res‐
ervoir pressures have been reached.
#
In the event of loss of pressure while
driving, immediately bring the vehicle to
a halt in accordance with the traffic
conditions.
#
Secure the vehicle using the parking
brake.
#
Consult a qualified specialist workshop
immediately.
#
Check the compressed-air brake system for
leaks ( / page 204).
#
Start the engine.
#
Leave the engine running until the
J
warn‐
ing lamp in the instrument cluster goes out.
#
Call up the menu window Reservoir pressure
in the instrument cluster and check the cur‐
rent reservoir pressure.
#
Observe the event windows and the indicator
lamps in the status area of the on-board com‐
puter/instrument cluster for the reservoir
pressure and the compressed-air brake sys‐
tem.
Checking supply pressure in transmission/
clutch circuit
&
WARNING Risk of accident if the pres‐
sure is too low
In the event of pressure loss or insufficient
reservoir pressure in the transmission/clutch
circuit, you can no longer change gears
#
Do not set the vehicle in motion, or if it
is moving then stop it immediately in
accordance with the traffic regulations.
#
Secure the vehicle against rolling away,
e.g. with the parking brake.
#
Contact a qualified specialist workshop
immediately to have the compressed-air
system repaired.
The supply pressure in the transmission/clutch
circuit is only filled after brake circuits 1 and 2. If
the supply pressure in the transmission/clutch
circuit is too low, the on-board computer shows
the yellow event window
:
Transmission/
clutch reserve pressure too low .
#
Start the engine.
#
Leave the engine running until the event win‐
dow
:
Transmission/clutch reserve pres-
sure too low in the on-board computer goes
out.
Checking the function of the compressed-air
dryer
& WARNING Risk of accident through con‐
densation levels that are too high
If the condensation level in the compressed-
air reservoirs is too high, the braking effect
can be reduced or the compressed-air brake
system can fail.
#
Check the compressed-air system for
condensation before starting a journey.
#
If the condensation level is high, have
the compressed-air brake system
checked as soon as possible at a quali‐
fied specialist workshop.
