152 STARTING AND OPERATING
Precautions While Driving With ACC
In certain driving situations, ACC may have
detection issues. In these cases, ACC may brake
late or unexpectedly. The driver needs to stay alert
and may need to intervene. The following are
examples of these types of situations:
TOWING A TRAILER
Towing a trailer is not recommended when using
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 move in and out of the line of travel,
which can cause your vehicle to brake or
accelerate unexpectedly.
Offset Driving Condition Example
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 vehicle in
front 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.
NOTE:
On tight turns ACC performance may be limited.
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 steepness of the hills,
ACC performance may be limited.
ACC Hill Example
LANE CHANGING
ACC may not detect a vehicle until it is completely
in the lane in which you are traveling. In the
following lane changing example, ACC has not yet
detected the vehicle changing lanes and it may not
detect the vehicle until it is too late for the ACC
system 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.
