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 0264.

this section and the ACC section before
using Super Cruise. SeeAdaptive Cruise
Control (Advanced) 0225.
An active Connected Service plan that
includes Super Cruise Services is required to
use Super Cruise.
{Warning
Super Cruise does not perform all aspects
of driving, nor does it do everything a
driver can do. Super Cruise only steers to
maintain vehicle position in the current
lane or, under some circumstances, to
change lanes. Super Cruise can only be
used with Adaptive Cruise Control.
Super Cruise does:
.Not prevent crashes or warn of
possible crashes.
.Not steer to avoid stopped or
slow-moving vehicles, cross-traffic,
construction barriers or cones,
motorcycles, children, pedestrians,
animals, or other objects on the road.
.Not steer in response to vehicles or
objects next to your vehicle, including
vehicles attempting to enter your lane. (Continued)
Warning (Continued)
.Not respond to traffic lights, stop
signs, or other traffic control devices.
.Not respond to crossing traffic.
.Not make turns.
.Not steer to merge onto or to exit
highways.
.Not steer to avoid, or steer through
construction zones.
.Not function on surface streets.
.Not respond to oncoming traffic.
.Not function in city driving conditions.
{Warning
Some state and local laws may require
hands to be kept on the steering wheel
at all times. Only remove your hands
from the steering wheel if Super Cruise is
engaged, it is safe to do so, and it is
permitted by state and local laws.
{Warning
Failure to supervise the driving task and
to respond appropriately, even while
Super Cruise is operating, can cause a
crash. Super Cruise may not respond as
you would to all driving situations and
may not maintain lane position under all
conditions.
It is extremely important to pay
attention to the operation of the vehicle,
even while using Super Cruise. Do not
use a hand-held device while driving,
even with Super Cruise engaged. To
prevent serious injury or death:
.Always remain properly seated in the
driver seat with your seat belt
fastened.
.Never remove your hands from the
steering wheel when Super Cruise is
not operating.
.Always make sure traffic conditions
are safe before using Super Cruise.
.Always keep the entire vehicle and the
sensors clean. Sensors are on the
front, sides, and rear of the vehicle.(Continued)

signal lever to the neutral position, move
the lever in the opposite direction of the
lane change, or steer manually at
any time.
Automatic Lane Changes
Super Cruise System may initiate a single
lane change when enabled through vehicle

Attention to the Road
{Warning
Super Cruise is a driver assistance system
and cannot accurately detect or predict
all situations. Super Cruise is not a crash
avoidance system. To prevent serious
injury or death, you must supervise the
driving task and monitor the road
conditions. You may need to respond to
traffic events by steering, braking,
or accelerating. SeeDefensive Driving
0 185. Super Cruise also cannot determine
whether you are awake, asleep, impaired,
or properly focused on safe driving. The
vehicle could crash into other vehicles,
drive out of the lane, or drive off the
road. Complete attention is always
required while driving, even while using
Super Cruise. Be prepared to take over
steering or apply the brakes at any time.
{Warning
To prevent serious injury or death, be
alert and pay special attention when
passing highway exits, entrances, and
crossings with Super Cruise, and be ready
to take control of the vehicle when
necessary. Changes in lane markings
around exits and entrances can
momentarily cause Super Cruise to not
detect the correct lane. If this occurs,
Super Cruise may attempt steering inputs
to bring the vehicle back into the correct
lane and, in rare circumstances, could
over-correct and cause the vehicle to
momentarily cross into a lane next to
your vehicle unless you manually steer to
maintain your lane position. The Driver Attention System (DAS) on the
steering column continually monitors driver
head and eye position to estimate driver
attention to the road. The camera does not
record or share pictures, audio, or video.
Sunglasses, hats, or other types of clothing
that change the shape of the head may
interfere with camera performance. To
improve camera performance, raise or lower
the steering wheel, or change the seat
position.
