ACC IndicatorRegular Cruise
Control Indicator
When ACC is engaged, a green
\
indicator will be lit on the instrument
cluster. When the regular cruise
control is engaged, a green
J
indicator will be lit on the instrument
cluster.
When the vehicle is turned on, the
cruise control mode will be set to the
last mode used before the vehicle was
turned off.
{Warning
Always check the cruise control
indicator on the instrument cluster
to determine which mode cruise
control is in before using the
feature. If ACC is not active, the
vehicle will not automatically brake
for other vehicles, which could
cause an accident if the brakes are
not applied manually. You and
others could be seriously injured or
killed.
Setting Adaptive Cruise Control
If
Jis on when not in use, it could
get pressed and go into ACC when not
desired. Keep
Joff when cruise is
not being used.
Select the set speed desired for ACC.
This is the vehicle speed when no
vehicle is detected in its path.
While the vehicle is moving, ACC will
not set at a speed less than 25 km/h
(15 mph), although it can be resumed
when driving at lower speeds. To set ACC while moving:
1. Press
J.
2. Get up to the desired speed.
3. Press and release SET−.
4. Remove your foot from the accelerator.
After ACC is set, it may immediately
apply the brakes if a vehicle ahead is
detected closer than the selected
following gap.
ACC can also be set while the vehicle
is stopped if ACC is on and the brake
pedal is applied.
The ACC indicator displays on the
instrument cluster and Head-Up
Display (HUD), if equipped. When ACC
is turned on, the indicator will be lit
white. When ACC is engaged, the
indicator will turn green.

234 DRIVING AND OPERATING
Approaching and Following a
Vehicle
The vehicle ahead indicator is on the
instrument cluster 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.
ACC automatically slows the vehicle
down and adjusts vehicle speed to
follow the vehicle in front at the
selected follow gap. The vehicle speed
increases or decreases to follow the
vehicle in front of you, but will not
exceed the set speed. It may apply
limited braking, if necessary. When
braking is active, the brake lamps will
come on. The automatic braking mayfeel or sound different than if the
brakes were applied manually. This is
normal.
Stationary or Very Slow-Moving
Objects
{Warning
ACC may not detect and react to
stopped or slow-moving vehicles
ahead of you. For example, the
system may not brake for a vehicle
it has never detected moving. This
can occur in stop-and-go traffic or
when a vehicle suddenly appears
due to a vehicle ahead changing
lanes. Your vehicle may not stop
and could cause a crash. Use
caution when using ACC. Your
complete attention is always
required while driving and you
should be ready to take action and
apply the brakes.
ACC Automatically Disengages
ACC may automatically disengage and
you will need to manually apply the
brakes to slow the vehicle if:
.
The sensors are blocked.
. The Traction Control System (TCS)
or StabiliTrak/ESC system has
activated or been disabled.
. There is a fault in the system.
. The radar falsely reports blockage
when driving in a desert or remote
area with no other vehicles or
roadside objects. A DIC message
may display to indicate that ACC
is temporarily unavailable.
The ACC indicator will turn white
when ACC is no longer active.
In some cases, when ACC will not
activate, regular cruise control may be
used. See “Switching Between ACC and
Regular Cruise Control ”previously in
this section. Always consider driving
conditions before using either cruise
control system.

DRIVING AND OPERATING 237
Other Vehicle Lane Changes
ACC will not detect a vehicle ahead
until it is completely in the lane. The
brakes may need to be manually
applied.
Do Not Use ACC on Hills and When
Towing a Trailer
Do not use ACC when driving on steep
hills or when towing a trailer. For
towing capability, seeTrailer Towing
0 284. ACC will not detect a vehicle in
the lane while driving on steep hills.
The driver will often need to take over
acceleration and braking on steep
hills, especially when towing a trailer.
If the brakes are applied, the ACC
disengages.
Disengaging ACC
There are three ways to
disengage ACC:
. Step lightly on the brake pedal.
. Press
*.
. Press
J.
Erasing Speed Memory
The ACC set speed is erased from
memory if
Jis pressed or if the
ignition is turned off.
Cleaning the Sensing System
The camera sensor on the windshield
behind the rearview mirror and the
radar sensors on the front of the
vehicle can become blocked by snow, ice, dirt, or mud. These areas need to
be cleaned for ACC to operate
properly.
If ACC will not operate, regular cruise
control may be available. See
“Switching Between ACC and Regular
Cruise Control
”previously in this
section. Always consider driving
conditions before using either cruise
control system.
For cleaning instructions, see
“Washing the Vehicle ”under Exterior
Care 0372.
System operation may also be limited
under snow, heavy rain, or road spray
conditions.
Super Cruise
If equipped, Super Cruise can steer to
maintain lane position under certain
conditions on limited access freeways
that are separated from opposing
traffic.

To prevent serious injury or death,
be alert and pay special attention
when passing freeway exits and
entrances with Super Cruise, and be
ready to take control of the vehicle
when necessary. Changes in lane
markings around freeway exits and
entrances can momentarily cause
Super Cruise to not detect the
correct lane. If this occurs, Super
Cruise may attempt steering inputs(Continued)
Warning (Continued)
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
