Do not activate the continuous brake and do
not shift to a lower gear in order to increase
the engine's braking effect on a slippery road
surface.
The engine brake and retarder are used as a
continuous brake.
You can utilise the engine's braking effect,
particularly on long downhill gradients if you:
R
activate the continuous brake
R
shift to a lower gear in good time
Slowly depress the brake pedal if the engine's
braking effect is insufficient when driving
downhill.
Vehicles without a retarder are equipped with
only two brake stages.
Operation of the continuous brake (see the
vehicle/device operating instructions).
The
Ã
indicator lamp in the instrument
cluster is lit when the continuous brake is
active.
When ABS (Anti-lock Braking System) inter-
venes, the continuous brake is switched off.
The
Ã
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 37).
The maximum permissible engine speed is
restricted if necessary, depending on the
vehicle/device application.
Observe the vehicle/device Operating
Instructions.
At very low outside temperatures, the engine
brake has limited or no effect after the engine
has been started.
Operation of the engine brake (see the vehi-
cle/device Operating Instructions).
Retarder
Operation of the retarder; see the vehicle/
device Operating Instructions.
Idling speed
After the engine has been started, idling
speed is regulated automatically. The engine
idling speed may differ in certain operating
conditions depending on the engine or on
vehicles with power take-off.
You can set the idling speed to between
approximately 600 and 800 rpm.
The engine idling speed is raised at very low
outside temperatures.
You can set the speed to the working speed
via the electronic engine management sys-
tem. This makes it possible to drive auxiliary
equipment such as pumps at their working
speed. For setting the working speed, see the
vehicle operating instructions.
Operational monitoring
Charge current
The charge current indicator lamp must go
out after the engine has started.
If the
#
indicator lamp does not go off or
lights up when the engine is running, switch
off the engine. Searching for and eliminating
the cause of the malfunction (
Y
page 71).
Electronic engine management
The indicator and warning lamps must go out
after the engine has started.
If an indicator lamp or warning lamp does not
go out, or if it lights up while the engine is
running, there is a malfunction in the elec-
tronic engine management system.
Searching for and eliminating the cause of the
malfunction (
Y
page 71).
