114 STARTING AND OPERATING
If an obstruction is detected, clean the area of the wind-
shield opposite the interior rearview mirror, where the
camera is located, as well as the area of the front
fascia/bumper where the sensor is located. Then check
that the message has disappeared.
When the conditions limiting the system function as
been corrected, normal operation will resume.
Should the fault persist, contact an authorized dealer.
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 merg-
ing in from a side lane. There may not be sufficient dis-
tance 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 increase or decrease the vehicle speed for stabil-
ity, with no vehicle ahead 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
ACC performance may be limited 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 hill.
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's 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.
Lane Changing Example
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 may not be
sufficient distance to the vehicle ahead.
