Steering assistance
The current status of steering
assistance is indicated by the
colour of the steering wheel's
symbol:
• GREEN steering wheel indi-
cates active steering assis-
tance
• GREY steering wheel (as in illustration) indi-
cates deactivated steering assistance.
Pilot Assist steering assistance takes into
account the speed of the preceding car and
the lane markings. The driver can at any time
ignore the Pilot Assist steering recommenda-
tion and steer in another direction, e.g. to
change lane or avoid an obstruction on the
road.
If Pilot Assist cannot interpret the lane unam-
biguously, e.g. if the camera and radar unit
does not see the lane's side markings, Pilot
Assist temporarily deactivates steering assis-
tance, but resumes it if the lane can be inter-
preted again - although the speed and dis-
tance control functions remain active. The
steering wheel vibrates slightly when deacti-
vated temporarily in order to alert the driver to
the change.

WARNING
Pilot Assist steering assistance is automati-
cally deactivated and is resumed without
prior warning.
Round bends and when the road splits
Pilot Assist interacts with the driver, who
should therefore not wait for the steering
assistance from Pilot Assist but should always
be prepared to increase his/her own steering
input, especially in bends.
When the car approaches an exit or if the lane
splits, the driver should steer towards the
desired lane so that Pilot Assist can detect the
desired direction.
Hands on the steering wheel
In order for Pilot Assist to function, the driver's
hands must be on the steering wheel. It is also
important for the driver always to carry on
being active and alert when driving as Pilot
Assist is unable to read all situations and the
function may toggle between off and on with-
out prior warning.
If Pilot Assist detects that the
driver does not keep his/her
hands on the steering wheel,
the system gives a warning
with a symbol and text mes-
sage in the driver display in
order to prompt the driver to
actively steer the car.
If the driver's hands still cannot be detected
on the steering wheel after a few seconds, the
prompt to actively steer the car is repeated,
supplemented by an acoustic signal.
If Pilot Assist cannot detect the driver's hands
on the steering wheel after a further few sec-
onds, the warning signal becomes intensive
and the steering function is deactivated. Pilot
Assist must then be restarted using the steer-
ing wheel button .
