: In order to confirm operation, the BSM outside rear view mirror indica-
tors illuminate in the following situations:
• When the “ENGINE START STOP” switch is turned to IGNITION
ON mode while the BSM main switch is set to ON.
• When the BSM main switch is set to ON while the “ENGINE START
STOP” switch is in IGNITION ON mode.
If the system is functioning correctly, the BSM outside rear view mirror

2402-4. Using other driving systems
■
Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following situations: ●
Actual vehicle speed is more than approximately 10 mph (16 km/h) below the
set vehicle speed.
At this time, the memorized set speed is not retained.●
Actual vehicle speed falls below approximately 25 mph (40 km/h).●
Enhanced VSC is activated. (vehicles with enhanced VSC)●
VSC is activated. (vehicles with VSC)■
Radar 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 canc eled if an obstruction is detected.
■
Warning lights, messages and buzzer s for dynamic radar cruise control
Warning lights, messages and buzzers are us ed to indicate a system malfunction or
to inform the driver of the need for caution while driving. (  P. 7 5 9 )Grille cover
Radar sensor

2822-4. Using other driving systems
■
Obstacles 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. ■
Situations in which the pre-collision system does not function properly
The system may not function effectively in situations such as the following: ●
On roads with sharp be nds or uneven surfaces●
If a vehicle suddenly moves in front of your vehicle, such as at an intersection●
If a vehicle suddenly cuts in front of your vehicle, such as when overtaking●
In inclement weather such as heav y rain, fog, snow or sand storms●
When your vehicle is skiddi ng with the VSC system off●
When an extreme change in vehicle height occurs●
When the axis of the radar is out of adjustment■
Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in the
sensors being unable to detect obstacles, the pre-collision system will be automati-
cally disabled. In this case, the system will not activate even if there is a collision pos-
sibility.■
When there is a malfunction in the system, or if the system is temporarily unus-
able
Warning lights and/or warning messages will turn on or flash. (  P. 744, 754)
