220 DRIVING AND OPERATING
Selecting the Follow Distance
When a slower moving vehicle is
detected ahead within the selected
following gap, ACC will adjust the
vehicle's speed and attempt to
maintain the follow distance gap
selected.
Press on the steering wheel to
adjust the following gap. Each press
cycles the gap button through three
settings: Far, Medium, or Near.
When pressed, the current gap setting
displays briefly on the instrument
cluster and HUD, if equipped.
Subsequent presses cycle the gap
button through three settings: Far,
Medium, or Near. The gap setting will
be maintained until it is changed.
Since each gap setting corresponds to
a following time (Far, Medium,
or Near), the following distance will
vary based on vehicle speed. The
faster the vehicle speed, the further
back your vehicle will follow a vehicle
detected ahead. Consider traffic and
weather conditions when selecting the
following gap. The range of selectable
gaps may not be appropriate for all
drivers and driving conditions.
Changing the gap setting
automatically changes the alert timing
sensitivity (Far, Medium, or Near) for
the Forward Collision Alert (FCA)
feature. See Forward Collision Alert
(FCA) System 0 230.
Alerting the Driver
Without Head-Up Display
With Head-Up Display
If ACC is engaged, driver action may
be required when ACC cannot apply
sufficient braking because of
approaching a vehicle too rapidly.
When this condition occurs, a series
of red lights or the collision alert
symbol on the HUD, if equipped, will
flash on the windscreen. Either eight
beeps will sound from the front,
or both sides of the Safety Alert Seat
will pulse five times. See Collision/
Detection Systems under Vehicle
Personalisation 0 145.
See Defensive Driving 0 179.
Approaching and Following a
Vehicle
The vehicle ahead symbol is in the
instrument cluster and HUD display,
if equipped.
The vehicle ahead symbol only
displays when a vehicle is detected in
your vehicle's path moving in the
same direction.
If this symbol is not displaying, ACC
will not respond to or brake to
vehicles ahead.
