WARNING
If you leave the vehicle while only the HOLD
function is braking the vehicle, the vehicle
can roll away in the following situations:
If there is a malfunction in the system or
R
in the power supply.
If the HOLD function is deactivated by
R
depressing the accelerator pedal, e.g. by
a vehicle occupant.
There is a risk of an accident.
Secure the vehicle against rolling away by
applying the parking brake before exiting the
vehicle.
Do not use the HOLD function when off-road,
on steep downhill or uphill gradients with slip-
pery or loose surfaces. Under these condi-
tions, the HOLD function may not be able to
hold the vehicle.
The function is activated when the ë indi-
cator lamp is shown in the on-board computer
display.
Continuous brake
Important safety notes
G
WARNING
If you activate the continuous brake or shift
to a lower gear on a slippery road surface in
order to increase the engine's braking
effect, the drive wheels may lose traction.
There is an increased risk of skidding and an
accident.
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.
You can utilise the engine's braking effect,
particularly on long downhill gradients if you:
activate the continuous brake
R
shift to a lower gear in good time
R
The continuous brake is activated automati-
cally if:
you depress the brake pedal
R
cruise control is active in overrun mode
R
Activating/deactivating the continu-

venes, the continuous brake is deactivated.
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 braking.
Observe the effective engine braking range
marked on the rev counter (
