Mercedes-Benz TRAVEGO, Operating Instructions Manual

Operation
Driving
Keep an eye on the rev counter while
driving.
Note:
Keep within the economical operating
range. Make sure that the engine speed
does not enter the danger zone (red
zone).
Notes for buses with GO 250 -8
transmission:
Danger.
The bus is equipped with a creep func-
tion. When the service brake is released
with the creep function activated, the bus
will creep forwards independently with the
engine continuing to run at idling speed.
If the engine speed drops below approx-
imately 550 rpm due to increased driving
resistance and/or you operate the ser-
vice brake at a low engine speed, the
electronics will disengage the clutch auto-
matically. This would interrupt the flow
of tractive power and the vehicle could
begin to roll back, e.g. on an uphill gradi-
ent.
Note:
For as long as both the accelerator pedal
and the brake pedal remain fully released,
the clutch will stay closed and the vehicle
will creep at idling speed. This works in
the 1st and 2nd gears.
Caution:
The least wearing on the clutch is idle
creeping. In stop-start traffic, therefore,
the brake pedal should be used as spar-
ingly as possible (under consideration of
the road and traffic situation) so that the
vehicle always creeps at idling speed. To
keep the driving speed as low as pos-
sible, it is possible to shift manually into
1st gear. If the speed of the bus is kept
low by means of the brake pedal, the
clutch will start to slip. This would res-
ult in increased clutch wear. If the brake
pedal is depressed rather more forcefully
(more than 10% brake pedal travel), the
clutch will open so far that it no longer
slips.
Note:
In the event of increased loading on the
clutch, an alert (grey) will appear on the
display screen. If the load persists, a
warning alert (yellow) will appear and the
creep function will be deactivated auto-
matically. This is designed to rule out an
overloading of the clutch by the creep
function.
