DRIVER SUPPORT
}}
* Option/accessory.
343
WARNING
Driver supports only warn of obstacles
which their radar unit has detected –
hence a warning may not be given, or it
may be given with a certain delay.
•
Never wait for a warning or interven-
tion. Apply the brakes when the situa-
tion requires.
NOTE
The driver supports can hold the car sta-
tionary for a maximum of 5 minutes – then
the parking brake is applied and the func-
tion is disengaged.
Before the driver supports can be reactiva-
ted, the parking brake must be released.
Cessation of automatic braking
In some situations, automatic braking ceases
on coming to a standstill and the function is
set in standby mode. This means that the
brakes are released and the car may start to
roll - the driver must therefore intervene and
brake the car himself/herself to keep it station-
ary.
This may take place in any of the following sit-
uations:
•
The driver puts his/her foot on the brake
pedal.
•
The parking brake is applied.
•
The gear selector is moved to P, N, or R
position.
•
The driver sets the adaptive cruise control
or Pilot Assist to standby mode.
Automatic activation of parking brake
The Parking brake is applied if the function is
holding the car stationary with the foot brake
and:
•
The driver opens the door or takes off
his/her seatbelt.
•
The function has kept the car stationary
for more than approx. 5 minutes.
•
The brakes have overheated.
•
The driver switches the engine off.

Lane assistance
The function of the Lane Keeping Aid (LKA
83
)
is to help the driver to reduce the risk of the
car accidentally leaving its own lane on
motorways and similar major routes.
Lane Keeping Aid steers the car back into its
lane and/or alerts the driver with vibrations in
the steering wheel.
Lane Keeping Aid is active within the speed
range 65200 km/h (40125 mph) on roads
with clearly visible side lines.
On narrow roads the function may be unavail-
able, in which case it goes into standby mode.
The function becomes available again when
the road is wide enough.
A camera reads the side lines of the road/lane.
