1. Blind spot monitor function
   • The blind spot monitor function is a function that assists the driver in making the decision to change lanes. The function uses quasi-millimeter wave radar to detect vehicles that are traveling in an adjacent lane in the area that is not reflected in the outer rear view mirror assembly. The function advises the driver of the existence of a vehicle by illuminating the outer rear view mirror indicator on the outer rear view mirror assembly.
   • If the turn signal switch is operated while the outer rear view mirror indicator on an outer rear view mirror assembly is illuminated, the indicator starts blinking to give additional warning to the driver.
2. RCTA function
   • The RCTA function is a function that informs the driver of an approaching vehicle from diagonally behind. The function uses quasi-millimeter wave radar to detect the positions of and relative speed to a vehicle. When the function determines that a vehicle is approaching this vehicle, this function informs the driver of it using the indicators and buzzer.

1. Operation conditions
   • The blind spot monitor main switch (combination switch assembly) is on.
   • Vehicle speed is more than approximately 16 km/h (10 mph).
2. Conditions in which a sensor can detect a vehicle

   The blind spot monitor function indicates detection of a vehicle in the detection area when either condition is met:

   • When a vehicle is detected in an adjacent lane overtaking this vehicle.
   • When a vehicle is detected entering the detection area because it changed lanes.
3. Detection area

   Vehicles in the following areas can be detected:

   *a	Vehicles in the following areas can be detected:
   *b	Within approximately 3.5 m (11.49 ft.) from the side of the vehicle
   *c	Within approximately 3 m (9.85 ft.) behind the rear bumper
   *d	Within approximately 1 m (3.29 ft.) forward of the rear bumper

1. Operation conditions:
   • The blind spot monitor main switch (combination switch assembly) is on.
   • The shift lever is in R.
   • The vehicle speed is less than approximately 8 km/h (5 mph).
2. Conditions in which a sensor can detect a vehicle

   The RCTA function indicates detection of a vehicle in the detection area when both conditions are met:

   • A vehicle is approaching this vehicle from diagonally behind.
   • The vehicle speed is approximately 8 km/h (5 mph) to 28 km/h (17 mph).
3. Detection area

   Vehicles in the following areas can be detected:

   *a	Vehicles in the following areas can be detected:
   *b	Within approximately 5.5 to 20 m (18.04 to 65.62 ft.) from the side of the vehicle (detection area changes according to vehicle speed)
   *c	Within approximately 6 m (19.69 ft.) behind the rear bumper

1. When the blind spot monitor main switch (combination switch assembly) is turned on with the engine switch on (IG), the outer rear view mirror indicator on each outer rear view mirror assembly illuminates for 3 seconds and the rear cross traffic alert buzzer (blind spot monitor buzzer) sounds for 1 second.
2. When the engine switch is turned from off to on (IG) with the blind spot monitor main switch (combination switch assembly) on, the outer rear view mirror indicator on each outer rear view mirror assembly illuminates for 3 seconds.

1. Operation for blind spot monitor function
   • When a sensor detects a vehicle in the blind spot area, the outer rear view mirror indicator on the outer rear view mirror assembly illuminates.
   • While the sensor is detecting a vehicle in the detection area and the indicator is illuminated, if the turn signal switch is operated, the outer rear view mirror indicator on the outer rear view mirror assembly starts blinking as shown in the illustration.

2. Operation for RCTA function
   • When all of the operation conditions for the RCTA function are met, the outer rear view mirror indicators on the outer rear view mirror assembly blink for 2.5 seconds and the rear cross traffic alert buzzer (blind spot monitor buzzer) sounds for 2.3 seconds as shown in the illustration.
