Driving and Operating 235
Do not install objects on top of the vehicle
that overhang and obstruct the front
camera, such as a canoe, kayak, or other
items that can be transported on a roof rack
system. See Roof Rack System 0 94.
Do not modify the hood, headlamps, or fog
lamps, as this may limit the camera’s ability
to detect an object.
Cleaning the Sensing System
The camera sensor on the windshield behind
the rearview mirror, and the sensors on the
front of the vehicle can become blocked by
snow, ice, dirt, mud, or debris. This area
needs 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 0 378.
Super Cruise
If equipped, Super Cruise can steer to
maintain lane position under certain
conditions on Super Cruise-enabled roads
that are separated from opposing traffic.
Super Cruise can also steer to perform a
lane change under certain conditions on
Super Cruise-enabled roads.
A lane change can be initiated by the driver
using the turn signal lever.
The Super Cruise System may initiate a lane
change maneuver in following scenarios:
.
to pass slower traffic
.
when the current lane is ending ahead
.
to return to the initial lane
See “Super Cruise Lane Change” later in this
section and Turn and Lane-Change Signals
