Rear cross traffic alert (RCTA) function<\/p>\n

\n
\n
\u2022 The rear cross traffic alert (RCTA) function starts detecting approaching vehicles when the selector lever is in the reverse position. The rear side radar sensor warns the driver when it detects an approaching vehicle passing over the alert line shown in the figure within 3.5 sec<\/span>.<\/p>\n\n\n\n

\u2022 When the rear side radar sensor detects an approaching vehicle, it warns the driver by flashing the blind spot monitoring (BSM) warning light and activating the blind spot monitoring (BSM) warning buzzer.<\/p>\n\n\n\n

System check<\/p>\n

\n
\n
\u2022 When the ignition is switched ON (engine off or on), the system checks the conditions for approx. 3 s<\/span>ec. During the system check, the blind spot monitoring (BSM) warning light turns on, and then turns off when the system check is finished. If a system malfunction is found, the i-ACTIVSENSE Warning Lamp remains turned on.<\/div>\n<\/dd>\n<\/dl>\n

Operation<\/p>\n

\n
\n
Warning<\/div>\n<\/dd>\n
\n
\u2022 The rear cross traffic alert (RCTA) system assists the driver in confirming the rear side of the vehicle when backing up. Because of the various restrictions in the system operations, a warning may not occur or it may be delayed even if there is a vehicle at the vehicle rear side. Do not rely completely on the system and always take responsibility as the driver in confirming the area behind the vehicle.<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
Caution<\/div>\n<\/dd>\n
\n
\n
\u2022 The system may operate under the following conditions even if a vehicle is not approaching.<\/div>\n
\n
\n
\u2015 An object that reflects the radio waves of the radar such as a parked vehicle, guardrail, or wall is directly next to your vehicle.<\/div>\n
\u2015 A vehicle approaching from the near left and right side of your vehicle slows down.<\/div>\n
\u2015 A vehicle approaching from the rear left and right side of your vehicle makes a right or left turn directly in front of your vehicle.<\/div>\n
\u2015 A vehicle overtakes your vehicle while it is stopped.<\/div>\n
\u2015 Your vehicle is in an area where strong radio waves or electrical noise may occur such as near a television tower or power plant.<\/div>\n<\/dd>\n<\/dl>\n
\u2022 In the following cases, the i-ACTIVSENSE warning indication\/warning light turns on and operation of the system is stopped. If the i-ACTIVSENSE warning indication\/warning light remains illuminated, have the vehicle inspected at an Authorized Mazda Dealer as soon as possible.<\/div>\n
\n
\n
\u2015 Some problem with the system including the Blind Spot Monitoring (BSM) warning indicator lights has occurred.<\/div>\n
\u2015 A large deviation in the installation position of a rear side radar sensor on the vehicle has occurred.<\/div>\n
\u2015 There is a large accumulation of snow or ice on the rear bumper near a rear side radar sensor.<\/div>\n
\u2015 Driving on snow-covered roads for long periods.<\/div>\n
\u2015 The temperature near the radar sensors becomes extremely hot due to driving for long periods on slopes during the summer.<\/div>\n
\u2015 The battery voltage has decreased.<\/div>\n<\/dd>\n<\/dl>\n
\u2022 Under the following conditions, the rear side radar sensor connot detect approaching vehicles or it might be difficult to detect them, and the system may not operate normally.<\/div>\n
\n
\n
\u2015 The vehicle speed when reversing is about 15 km\/h {9 mph} or faster.<\/div>\n
\u2015 The rear side radar sensor detection area is obstructed by a nearby wall or parked vehicle. (Reverse the vehicle to a position where the radar sensor detection area is no longer obstructed.)<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n<\/dd>\n<\/dl>\n

Rear cross traffic alert (RCTA) operation<\/p>\n

\n
\n
\u2022 When all of the following conditions are met, the rear cross traffic alert (RCTA) function goes on standby.<\/div>\n
\n
\n
Preconditions<\/div>\n<\/dd>\n
\n
\u2015 Rear cross traffic alert (RCTA) system is operating<\/div>\n
\u2015 Rear cross traffic alert (RCTA) system is normal<\/div>\n
\u2015 Selector lever R position signal is received<\/div>\n<\/dd>\n<\/dl>\n
\u2022 The warning is activated if the following condition is met.<\/div>\n
\n
\n
Operation condition<\/div>\n<\/dd>\n
\n
\u2015 An approaching vehicle is detected which will pass over the alert line within 3.5 sec<\/span>.<\/div>\n<\/dd>\n<\/dl>\n
\u2022 If any of the following conditions is met, the rear cross traffic alert (RCTA) function stops.<\/div>\n
\n
\n
Stop conditions<\/div>\n<\/dd>\n
\n
\u2015 Rear cross traffic alert (RCTA) system is stopped<\/div>\n
\u2015 Rear cross traffic alert (RCTA) system has a malfunction<\/div>\n
\u2015 Selector lever R position signal is not received<\/div>\n<\/dd>\n<\/dl>\n<\/dd>\n<\/dl>\n
\n
\n
If an approaching vehicle is on the left side<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
1. When the preconditions are met, the rear side radar sensor emits electromagnetic wave and starts detecting approaching vehicles.<\/div>\n
2. When the rear side radar sensor (LH) detects an approaching vehicle, it sends (1) the object information to the rear side radar sensor (RH).<\/div>\n
3. If the rear side radar sensor (RH) determines the approaching vehicle while reversing, it sends (2) a RCTA signal to the door-electrical supply unit (driver\u2019s side), door-electrical supply unit (passenger\u2019s side) and connectivity master unit (CMU) via the body control module (BCM).<\/div>\n
4. Based on the RCTA signal (2), the body control module (BCM) outputs the warning sound signal (3) to the Notification and Warning Speaker (Rear) and the Notification and Warning Speaker (Rear) sounds a warning.<\/div>\n
5. Based on the RCTA signal (2), the connectivity master unit (CMU) displays the warning indication (3) on the center display.<\/div>\n
6. Based on the RCTA signal (2), the door-electrical supply unit (driver\u2019s side) and door-electrical supply unit (passenger\u2019s side) flashes (3) the blind spot monitoring (BSM) warning light (LH) and blind spot monitoring (BSM) warning light (RH).<\/p>\n\n\n\n
