Blocked Sensor
WARNING:
Do not use ACC when towing a trailer with brake
controls. Aftermarket trailer brakes will not function properly when
ACC is activated because the brakes are electronically controlled. Failing to
do so may result in loss of vehicle control, which could result in serious
injury.
WARNING:
Do not use tires sizes other than those recommended
because this can affect the normal operation of ACC. Failing to do so
may result in a loss of vehicle control, which could result in serious injury.
A message regarding a blocked
sensor is displayed if the radar
signals from the sensor have been
obstructed. The sensor is located
behind a fascia cover near the driver
side of the lower grille. A vehicle
ahead cannot be detected and the
system will not function when the
radar signals are obstructed. The following table lists possible causes and
actions for this message being displayed.
