Reducing Speed While ACC is at a
Set Speed
If ACC is already activated, do one
of the following:
.
Use the brake to get to the
desired lower speed. Press
SET– down and release the
accelerator pedal. The vehicle
will now cruise at the lower
speed.
.
Press and hold SET– down until
the desired lower speed is
reached, then release it.
.
To decrease the vehicle speed in
smaller increments, press SET−
down 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−
down 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 on
page 5-10. The increment value
used depends on the units
displayed.
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 on
page 9-52.
