The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster
(Uplevel Cluster) 0 119 or
Instrument Cluster (Base Cluster)
0 117. 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 0 226.
Alerting the Driver
With Head-Up Display
Driving and Operating
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 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 0 151.
See Defensive Driving 0 182.
