ACC may occasionally provide braking and/or
a driver alert that you consider unnecessary.
This may be the system's response to signs,
guardrails, and other stationary objects in a
curve. This may also occur at the base of steep
hills. This is normal operation and your vehicle
does not require service.
Using ACC on Hills
When driving on hills, ACC may not detect a
vehicle in your lane. Depending on the speed,
vehicle load, traffic conditions, and the steep-
ness of the hills, ACC performance may be
limited.

Lane Changing
ACC will not detect a vehicle until it is com-
pletely in the lane in which you are traveling. In
the illustration shown, ACC has not yet de-
tected the vehicle changing lanes and it may
not detect the vehicle until it's too late for the
ACC system to take action. ACC will not detect
a vehicle until it is completely in the lane. There
will not be sufficient distance to the lane-
changing vehicle. Always be attentive and
ready to apply the brakes if necessary.

Narrow Vehicles
Some narrow vehicles traveling near the outer
edges of the lane or edging into the lane are not
detected until they have moved fully into the
lane. There will not be sufficient distance to the
vehicle ahead.
