Precautions while Driving with
ACC
Offset Driving
ACC may not detect a vehicle in the
same lane that is offset from your
direct line of travel, or a vehicle
merging in from a side lane. There
may not be sufficient distance to the
vehicle ahead. The offset vehicle may
6
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
stability 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.
Moreover, the radar sensor might
detect a vehicle on a nearby lane or no
longer detect the target vehicle.
Using ACC on Hills
When driving on steep hills, ACC may
not detect a vehicle in your lane when
vehicle reaches the crest. Depending
on the speed, vehicle load, traffic
conditions, and the steepness of the
hills, ACC performance may be limited.
Lane Changing
ACC may not detect a vehicle until it
is completely in the lane in which you
are travelling.
In the illustration shown, ACC has not
yet detected the vehicle changing lane
and it may not detect the vehicle until
it is too late for the driver to take
action. ACC may not detect a vehicle
until it is completely in the lane. There
may not be sufficient distance to the
lane changing vehicle.
Always be attentive and ready to apply
the brakes if necessary.
