get object is a stationary vehicle or some
other object, e.g. a speed bump.

Automatic braking with Pilot Assist
Pilot Assist has a special brake function in slow
traffic and while stationary.
Brake function in slow queues and
while stationary
For shorter stops in connection with inching in
slow traffic or at traffic lights, driving is automati-
cally resumed if the stops do not exceed
approx. 3 seconds - if it takes longer before the
vehicle in front starts moving again then Pilot
Assist is set in standby mode with automatic
braking.
Pilot Assist is reactivated in the following
–
way:
Press the steering wheel button
•
Depress the accelerator pedal.
•
> Pilot Assist resumes following the vehicle
ahead if it starts moving forward within
6 seconds.
NOTE
Pilot Assist can hold the car stationary for a
maximum of 5 minutes - then the parking
brake is applied and the function is disen-
gaged.
Before Pilot Assist 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 Pilot Assist 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 Pilot Assist 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 Pilot Assist is holding the car
stationary with the foot brake and:
the driver opens the door or takes off his/her
•
seatbelt
Pilot Assist has kept the car stationary for
•
more than approx. 5 minutes
the brakes have overheated
•
the driver switches the engine off manually.
