Medium Gap Setting with Trailer
Near Gap Setting with Trailer
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.
Courtesy Gap
Press and hold on the steering wheel
when vehicle is moving to temporarily
increase the gap with the vehicle ahead to
allow for merging traffic.
Press and hold when stopped to cancel
ACC from resuming automatically (if the
stop is brief) and remain stationary. This can
be used to allow traffic to merge between
you and the vehicle ahead. Press RES+ or
the accelerator pedal to resume ACC.
Following distance gap will return to the
original selection after hold.
Driving and Operating
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.
When this condition occurs, the collision
alert symbol 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. To view available settings
from the infotainment screen, touch Settings
> Vehicle > Collision/Detection Systems.
