Weather Conditions Affecting ACC

snow, heavy rain, or road spray conditions.
Accessory Installations and Vehicle
Modifications
Do not install or place any object around
the front camera windshield area that would
obstruct the front camera view.
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
.
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 ahead
of the rearview mirror and the radar sensors
on the front of the vehicle can become
blocked by snow, ice, dirt, mud, or debis.
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

in this
section. Always consider driving conditions
before using either cruise control system.
