Press and hold SET until the
desired lower speed is reached,
then release it.
To decrease the vehicle speed in
smaller increments, press SET to
the first detent. For each press, the
vehicle goes about 1 km/h (1 mph)
slower.
To decrease the vehicle speed in
larger increments, press SET to
the second detent. For each press,
the vehicle speed decreases to the
next 5 km/h (5 mph) mark on the
speedometer.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster (Base
Level) 0 112 or Instrument Cluster
(Uplevel) 0 114. The increment value
used depends on the units displayed.
Selecting the Follow Distance Gap
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. 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 0 214.
DRIVING AND OPERATING
Alerting the Driver
With Head-Up Display
Without 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, six 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 0 144.
