nRadar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-vehicle
distance control operates properly. (Some obstructions, such as snow, ice and plas-
tic objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected.
nWarning lights and messages for dynamic radar cruise control
Warning lights and messages are used to indicate a system malfunction or to inform
the driver of the need for caution while driving. (→P. 5 5 1 )
nApproach warning
In the following instances, there is a possibility that the approach warnings will not
occur:
lWhen the speed of the vehicle ahead matches or exceeds your vehicle speed
lWhen the vehicle ahead is traveling at an extremely slow speed

2-4. Using other driving systems
When the system is activated in the situations described above, there is also a possi-
bility that the seat belts will retract quickly and the brakes will be applied with a force
greater than normal. When the seat belt is locked in the retracted position, stop the
vehicle in a safe place, release the seat belt and refasten it.
nObstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may also be
occasions when the sensor cannot detect pedestrians, animals, bicycles, motorcy-
cles, trees, or snowdrifts.
nWhen there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. (→P. 535, 545)
