DRIVER SUPPORT
}}
* Option/accessory. 333
NOTE
The driver supports can hold the car station-
ary for a maximum of 5 minutes – then the
parking brake is applied and the function is
disengaged.
Before the driver supports can be reactivated,
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 him-
self/herself to keep it stationary.
This may take place in the following situations:
•
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 posi-
tion
•
the driver sets the function in the standby
mode.
Automatic activation of parking brake
In certain situations, the parking brake is applied
in order to keep the car stationary.
This takes place 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 manually.

Overtaking Assistance
Overtaking Assistance can help the driver when
overtaking other vehicles. This function can be
used with Pilot Assist or adaptive cruise control
*
(ACC
57
).
How overtaking assistance works
When Pilot Assist or ACC is following another
vehicle and the driver indicates the intention to
overtake by activating the direction indicator
58
,
the systems help by accelerating the vehicle
towards the vehicle in front
before the driver’s
vehicle reaches the overtaking lane.
The function then delays reducing speed in order
to avoid premature braking when the driver’s car
is approaching a slower vehicle.
The function remains active until the driver’s vehi-
cle has cleared the overtaken vehicle.
WARNING
Be aware that this function can be activated
in more situations than during overtaking, e.g.
when a direction indicator is used to indicate
a change of lane or exit to another road – the
car will then accelerate briefly.
