Chevrolet Traverse Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
13527526) - 2020 - CRC - 4/10/19
Driving and Operating 209
Approaching and Following a
Vehicle
The vehicle ahead indicator is in the
instrument cluster.
The vehicle ahead indicator only
displays when a vehicle is detected
in your vehicle’s path moving in the
same direction.
If this symbol 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
lights will come on. The automatic
braking may feel 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 the driver 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 vehicle 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when ACC is no longer active.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.
