DRIVER SUPPORT
Drive modes when using time
interval to vehicles
The driver can select different driving styles
for how driver support should maintain the
preset time interval to the vehicle ahead.
Selection is made via the drive mode control
DRIVE MODE.
Select one of the following options:
Pure
– The driver support focuses on
•
good fuel economy, which means longer
time interval to the vehicle ahead.
Hybrid – The driver support focuses on
•
following the set time interval to the vehi-
cle ahead as smoothly as possible.
Power – The driver support focuses on
•
following the set time interval to the vehi-
cle ahead more closely, which in certain
cases may mean heavier acceleration and
braking.

Automatic braking with driver
support
The driver supports of adaptive cruise con-
trol* and Pilot Assist* have a special brake
function in slow traffic and while stationary.
In certain situations, the parking brake is
applied in order to keep the car 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 auto-
matically resumed if the stops do not exceed
approx. 3 seconds - if it takes longer before
the vehicle in front starts moving again then
the driver support function is set in standby
mode with automatic braking.
The function is reactivated in one of the
–
following ways:
Press the steering wheel button
•
Depress the accelerator pedal.
•
> The function resumes following the
vehicle ahead if it starts moving for-
ward within approx. 6 seconds.
WARNING
A significant increase in speed may follow
when the speed is resumed with the
steering wheel button.
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 10 minutes –
then the parking brake is applied and the
function is disengaged.
Before the driver supports can be reactiva-
ted, the parking brake must be released.
