X If the engine fails to start: rectify the cause of
the poor starting characteristics.
Possible causes of poor starting characteristics
are, for example:
R
a blocked fuel filter
R
an empty fuel tank (
Y
page 315)
R
fuel system not bled (
Y
page 376)
X
Repeat the starting procedure.
X If the engine still fails to start, contact a quali-
fied specialist workshop.
Safety inspection
Checking the reservoir pressure in the
compressed-air brake system
G
WARNING
It is not possible to brake the vehicle if the
compressed-air brake system has a leak or if
there insufficient reservoir pressure. There is
a risk of an accident.
Do not pull away until the required reservoir
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.
Have the compressed-air system repaired at a
qualified specialist workshop.
X Start the engine.
X Leave the engine running until the
J
warn-
ing lamp in the instrument cluster goes out.
For vehicles without BlueTec
®
exhaust gas
after treatment, the reservoir pressure dis-
play of the brake circuit in the instrument
cluster shows at least 11 bar.
X
For BlueTec
®
vehicles, call up the
Reserve
pressure menu window (
Y
page 148) and
check the current reserve pressure.
Observe the event window in the on-board com-
puter and the indicator lamps in the status area
of the on-board computer/instrument cluster
for the reservoir pressure and the compressed-
air brake system.
Checking the reservoir pressure in the
transmission/clutch circuit
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.
The reservoir pressure in the transmission/
clutch circuit is supplied once brake circuits 1
and 2 have been charged.
If the reservoir pressure in the transmission/
clutch circuit is too low, the on-board computer
will display the yellow
:
Transmission/
clutch reserve pressure too low event
window.
X
Start the engine.
X
Leave the engine running until the yel-
low
:
Transmission/clutch reserve
pressure too low event window in the on-
board computer goes out.
Checking the function of the compressed-
air dryer
G
WARNING
If the condensation level in the compressed-
air reservoir is too high, the braking effect may
reduce or the brake system may fail. There is
a risk of an accident.
Check the compressed-air system for con-
densation before starting a journey. If the
condensation level is high, have the
compressed-air brake system checked at a
qualified specialist workshop immediately.
