Drive modes when using time
interval to vehicle
The driver can choose different drive modes
to determine how driver support should
maintain a time interval to the vehicle ahead.
Settings are made using the DRIVE MODE
controls.
Select one of the following:
Eco
- Driver support will focus on provid-
•
ing good fuel economy, which will
increase the time interval to the vehicle
ahead.
Comfort - Driver support will focus on fol-
•
lowing the set time interval to the vehicle
ahead as smoothly as possible.
Dynamic * - Driver support will focus on
•
following the set time interval to the vehi-
cle ahead more exactly, which could mean
faster acceleration and heavier braking.

Auto-hold braking with driver
support
The driver support functions Adaptive Cruise
Control* and Pilot Assist* have a special brake
function in slow traffic and while stationary.
In certain situations, the parking brake will be
applied to keep the vehicle at a standstill.
Braking function in slow traffic and at
a standstill
In slow-moving, stop-and-go traffic or when
stopped at a traffic light, driving will resume
automatically if the vehicle is stopped for less
than approx. 3 seconds. If it takes more than 3
seconds for the vehicle ahead to begin moving
again, the driver support function will go into
standby mode and the auto-hold brake func-
tion will activate.
The function can be reactivated by:
–
Pressing the button on the steer-
•
ing wheel keypad.
Pressing the accelerator pedal.
•
> The function will resume following the
vehicle ahead if it begins to move
within approx. 6 seconds.
WARNING
A noticeable increase in speed may follow
when the speed is resumed with the
steering wheel button.
DRIVER SUPPORT
WARNING
The driver support system only issues a
warning for obstacles detected by its radar
sensor – thus, a warning may come after a
delay or not at all.
Never wait for a warning or assistance.
•
Apply the brakes when necessary.
NOTE
Driver support can keep the vehicle sta-
tionary for no more than 10 minutes – after
that time the parking brake is applied and
the function is deactivated.
The parking brake must be released before
driver support can be reactivated.
