Setting the time interval for Pilot
Assist
Pilot Assist can be set with different time inter-
vals.
Different time intervals to the
vehicle in front can be selected
and shown in the driver display
as 1-5 horizontal lines - the
more lines the longer the time
interval. One line represents
about 1 second to the vehicle
in front, 5 lines represents about 3 seconds.
NOTE
When the symbol in the driver display shows
a car and a steering wheel, Pilot Assist fol-
lows a vehicle in front at a preset time gap.
When only one steering wheel is shown, there
is no vehicle within a reasonable distance
ahead.
NOTE: The illustration is schematic - details may vary depending on car model.

Press the steering wheel button (1) or (2) to
–
increase or decrease the time interval.
> The distance indicator (3) shows the cur-
rent time interval.
In order to follow the vehicle ahead in a smooth
and comfortable way, Pilot Assist allows the time
interval to vary noticeably in certain conditions.
For example, at low speed, when the distances
become short, Pilot Assist increases the time
interval slightly.
NOTE
•
The higher the speed the longer the cal-
culated distance in metres for a given
time interval.
•
Only use the time intervals permitted by
local traffic regulations.
•
If Pilot Assist does not seem to respond
with a speed increase when activated, it
may be because the time window to the
vehicle ahead is shorter than the set time
window.
WARNING
•
Only use a time window that suits the
current traffic conditions.
•
The driver should be aware that short
time windows limit the amount of time
available to react and take action if an
unexpected traffic situation arises.
