Deactivation of the Auto-hold brake function
In certain situations, Auto-hold will be deactivated
when the vehicle is at a standstill and Pilot Assist
will go into standby mode. This means that the
brakes will be released and the vehicle could
begin to roll. The driver must actively apply the
brakes to keep the vehicle stationary.
This can occur if:
•
the driver depresses the brake pedal
•
the parking brake is applied
•
the gear selector is moved to the P, N or R
positions
•
the driver puts Pilot Assist in standby mode.
Auto Activate Parking Brake
In certain situations, the parking brake will be
applied to keep the vehicle at a standstill.
This occurs if Pilot Assist is keeping the vehicle
stationary using the brakes and:
•
the driver opens the door or unbuckles
his/her seat belt
•
Pilot Assist has kept the vehicle at a stand-
still for more than approx. 5 minutes
•
the brakes overheat
•
the driver switches off the engine manually.

Pilot Assist limitations
Pilot Assist functionality may be reduced in cer-
tain situations.
Pilot Assist is a driver support function designed
to simplify driving and assist the driver in many
situations. However, the driver is always responsi-
ble for maintaining a suitable distance to vehicles
or objects around it and ensuring that the vehicle
is correctly positioned in the traffic lane.
DRIVER SUPPORT
WARNING
In some situations, Pilot Assist may have trou-
ble helping the driver properly or may be
deactivated automatically – we advise against
using Pilot Assist in such cases. Examples of
such situations include:
•
the lane markings are worn, missing or
cross each other.
•
lane division is unclear, for example, when
the lanes divide or merge or at exits or
when there are multiple sets of markings.
•
edges or other lines than lane markings
are present on or near the road, e.g.
curbs, joints or repairs to the road sur-
face, edges of barriers, roadside edges or
strong shadows.
•
the lane is narrow or winding.
•
the lane contains ridges or holes.
•
weather conditions are poor, e.g. rain,
snow or fog or slush or reduced visibility
with poor light conditions, backlighting,
wet road surface, etc.
The driver should also note that Pilot Assist
has the following limitations:
•
High curbs, roadside barriers, temporary
obstacles (traffic cones, safety barriers,
etc.) are not detected. Alternatively, they
may be detected incorrectly as lane mark-
ings, with a subsequent risk of contact
between the vehicle and such obstacles.
