To decrease 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.
To decrease speed while the
vehicle is stopped, press SET
until the desired set speed is
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 0 228.
Alerting the Driver
If ACC is engaged, driver action may
be required when ACC cannot apply
sufficient braking because of
approaching a vehicle too rapidly.
DRIVING AND OPERATING
When this condition occurs, the
collision alert symbol on the HUD will
flash on the windshield. 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
Personalization 0 152.
See Defensive Driving 0 185.
Approaching and Following a
Vehicle
The vehicle ahead indicator is on the
instrument cluster, infotainment
display, and HUD display. This
indicator only displays when a vehicle
is detected in your vehicle s path
moving in the same direction.
If this indicator is not displaying, ACC
will not respond to or brake for
vehicles ahead.
