Precautions While Driving With ACC
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or unexpect-
edly. The driver needs to stay alert and may need to
intervene.
Adding A Trailer Hitch
The weight of a trailer/hitch may affect the performance
of ACC. If there is a noticeable change in performance
following the installation of a trailer/hitch, or if the ACC
performance does not return to normal after removing
the trailer/hitch see your authorized dealer.
Offset Driving
ACC may not detect a vehicle in the same lane that is
offset from your direct line of travel. There will not be
sufficient distance to the vehicle ahead. The offset vehicle
may move in and out of the line of travel, which can
cause your vehicle to brake or accelerate unexpectedly.
Turns And Bends
When driving on a curve with ACC engaged, the system
may decrease the vehicle speed and acceleration for
convenience reasons, with no target vehicle detected.
Once the vehicle is out of the curve the system will
resume your original Set Speed. This is a part of normal
ACC system functionality.
