DRIVER SUPPORT
* Option/accessory.
324
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 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
position
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 man-
ually.

Drive mode for driver support
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.
