Note

• The traffic sign recognition system (TSR) does not operate if the SD card (genuine Mazda) is not inserted.

Display example

Sign	Active driving display
Speed limit signs (including auxiliary signs)
Do not enter sign

Excessive speed warning

• The excessive speed warning activates the warning indicator and warning sound if the vehicle speed, according to the excessive speed set in the personalization features, exceeds the speed limit sign displayed on the active driving display and the instrument cluster.

Personalization feature

• The traffic sign recognition system (TSR) can be changed as follows.For details on the personalization features, refer to the [PERSONALIZATION FEATURES]

― Excessive speed warning pattern

― Warning threshold of excessive speed warning

Operation

Speed limit sign indications (including auxiliary signs)

1.The forward sensing camera (FSC) sends (1) the speed limit sign (including auxiliary signs) signal to the body control module (BCM) when all of the following conditions are met.

• Vehicle speed is 1 km/h {0.6 mph} or more.

• FSC recognizes speed limit sign (including auxiliary signs) and it disappears from FSC angle of view

2.The connectivity master unit (CMU) sends (1) the speed limit signal to the body control module (BCM).

3.The body control module (BCM) determines the speed limit value based on the information from the forward sensing camera (FSC) and connectivity master unit (CMU) and sends the speed limit sign display signal (2) to the active driving display and instrument cluster.

4.The active driving display and the instrument cluster display (3) the speed limit sign (including auxiliary signs) when it receives the speed limit sign (including auxiliary signs) display signal.

5.The body control module (BCM) sends (4) the speed limit sign (including auxiliary signs) non-display signal to the active driving display and the instrument cluster when any of the following conditions is met.

• The body control module (BCM) determines that the vehicle has traveled approx. 2,000 m {1.2 mile} to 3,000 m {1.9 mile} ( approx. 50 m {0.03 mile} when auxiliary signs are recognized) based on the information from the connectivity master unit (CMU).

• The body control module (BCM) determines that the vehicle has changed lanes and there is no speed limits sign information from the connectivity master unit (CMU).

• The forward sensing camera (FSC) and the connectivity master unit (CMU) have a malfunction.

6.When the active driving display and the instrument cluster receive the speed limit sign (including auxiliary signs) non-display signal, the speed limit sign (including auxiliary signs) signal is switched to non-display (5).

Excessive speed warning function operation

1.If the displayed vehicle speed exceeds the speed limit that the body control module (BCM) determined by 1 km/h {0.6 mph}, the body control module (BCM) sends the TSR over speed signal to the active driving display and instrument cluster. At the same time, the body control module (BCM) outputs the warning sound signal to the Notification and Warning Speaker (Front).

2.When the active driving display and instrument cluster received the TSR over speed signal from the body control module (BCM), the active driving display and instrument cluster flash the speed limit sign.

Do not enter sign indication

1.The body control module (BCM) sends the do not enter sign display signal (1) to the active driving display and the instrument cluster when all of the following conditions are met.

• Vehicle speed is 1 km/h {0.6 mph} or more

• Vehicle speed is less than 60 km/h {37 mph}

• FSC recognizes do not enter sign and it disappears from FSC angle of view

2.When the active driving display and the instrument cluster receive the do not enter sign display signal (1), it displays (2) the do not enter sign.

3.When approx. 10 sec have elapsed since the body control module (BCM) sent the do not enter sign display signal, the body control module (BCM) sends the do not enter sign non-display signal to the active driving display and the instrument cluster (3).

4.When the active driving display and the instrument cluster receive the do not enter sign non-display signal (3), it turn off the do not enter sign display (4)

Stop sign indication

1.The body control module (BCM) sends (1) the stop sign display signal to the active driving display and the instrument cluster when all of the following conditions are met.

• Vehicle speed is 65 km/h {41 mph} or less

• FSC recognizes stop sign

2.The active driving display and the instrument cluster display (2) the stop sign when it receives the stop sign display signal.

3.When the vehicle is running approx. 12 km {7.5 mile} after the body control module (BCM) sent the stop sign display signal, the body control module (BCM) sends (3) the stop sign non-display signal to the active driving display and the instrument cluster.

4.The active driving display and the instrument cluster turn off (4) the stop sign.

No passing/End of no passing sign indication

1.The body control module (BCM) sends (1) the no passing sign display signal to the active driving display and the instrument cluster when the following conditions is met.

• FSC recognizes no passing sign and it disappears from FSC angle of view

2.The active driving display and the instrument cluster displays (2) the no passing sign when it receives the no passing sign display signal.

3.When the vehicle is running approx. 1000 m {0.62 mile} after the body control module (BCM) sent the no passing sign display signal, the body control module (BCM) sends (3) the no passing sign non-display signal to the active driving display and the instrument cluster.

4.The active driving display and the instrument cluster turns off (4) the no passing sign.

5.The body control module (BCM) sends (5) the end of no passing sign display signal to the active driving display and the instrument cluster when the following conditions is met.

• FSC recognizes no passing sign and it disappears from FSC angle of view

6.The active driving display and the instrument cluster displays (6) the end of no passing sign when it receives the end of no passing sign display signal.

7.When the vehicle is running approx. 375 m {0.23 mile} after the body control module (BCM) sent the end of no passing sign display signal, the body control module (BCM) sends (7) the end of no passing sign non-display signal to the active driving display and the instrument cluster.

8.The active driving display and the instrument cluster turns off (8) the end of no passing sign.
