Off-road ABS
(ABS in Low Range off-road programme)
When the Low Range off-road driving programme
is active, an ABS configuration specially matched
to off-road driving is activated automatically.
In the event of braking on loose ground, the
permissible slip values for ABS braking are
increased so that the off-road braking distance is
reduced (wheels dig into the surface).
If the driver needs to steer, this off-road driving
programme is automatically switched off to
maintain steerability.

Driving and Driving Safety
Hillholder (moving-off assistant)
In Tiptronic selector lever positions D and M, the
hillholder function makes it easier to move off
from a stand-still on an upward slope when the
engine is running. The driver does not have to
apply the brake.
The hillholder function is not active:
– In Tiptronic selector lever positions N and R,
– In the reduced driving programme and
– If not all of the wheels are touching the ground
(on difficult terrain, for example).
f For further information on driving off with the
hillholder function:
Please observe the chapter "STOPPING" on
Page 176.
Safety notes!
In spite of the advantages of the hillholder
function, it is still the driver's responsibility to
adapt his driving style and manoeuvres in line with
the prevailing conditions.
The increased safety that is provided should not
induce you to take greater risks with your safety.
The limits set by the physics of driving cannot be
overcome, even with the hillholder function.
Driving in limit situations should be avoided,
e.g. on icy slopes or on slippery surfaces. Assist-
ance by the hillholder is not guaranteed in these
and similar cases.
