Driver intervention prompt
If you take your hands off the steering wheel, the
system prompts you within a few seconds to take
over active steering by way of acoustic warnings and
a display on the instrument cluster.
If you do not react to this, the system provides an
additional warning by means of a short braking jolt.
The driver's belt is also briefly tensioned.
Travel Assist is then deactivated.
Alternatively, Emergency Assist will be activated
(with some equipment levels).
WARNING
The intelligent technology used in Travel Assist
cannot overcome the physical limits specified, and
functions only within the limits of the system.
Careless or unintentional use of Travel Assist can
cause accidents and serious injuries. The system is
not a substitute for the full concentration of the
driver.
x
Observe the system limits and information on
Adaptive Cruise Control (ACC) and the lane
keeping system (Lane Assist).
x
Adapt your speed and the distance from the ve-
hicles ahead to suit visibility, weather, road and
traffic conditions.
x
Never use Travel Assist in poor visibility, on
steep or winding roads, or on slippery road sur-
faces, e.g. due to snow, ice, wet roads, loose
chippings, or on flooded roads.
x
Never use Travel Assist offroad or on unsurfaced
roads. Travel Assist is designed for use on sur-
faced roads only.
x
Travel Assist does not react to persons, animals
or vehicles crossing or approaching in the same
lane.
x
Brake immediately if a brake request is dis-
played on the instrument cluster display or if
the speed reduction by Travel Assist is not suffi-
cient.
x
Brake if the vehicle starts rolling unintentional-
ly, e.g. after a brake request.
x
Your hands should always be on the steering
wheel so that you are ready to steer at any
time. The driver is always responsible for stay-
ing in the lane.
x
Take control of the vehicle immediately if
a driver intervention prompt appears on the in-
strument cluster display.
x
Be prepared to control the speed yourself at all
times.
