Function
• The active driving display displays the following vehicle information.
-
― Current vehicle speed
― Cruise control set vehicle speed (with cruise control system)
― Adjustable speed limiter set vehicle speed (with Adjustable speed limiter system)
― Mazda radar cruise control (MRCC) system operation status or warning display (with MRCC)
― Smart brake support (SBS) warning display (with SBS)
― Distance recognition support system (DRSS) system operation status display (with DRSS)
― Smart city brake support (SCBS) warning display (with SCBS)
― Lane departure warning system (LDWS) operation status or warning display (with LDWS)
― Travel direction (turn by turn (TBT)) display (with car navigation system)
• The active driving display displays the following content based on the following CAN signals when the engine is started. Refer to reference for details on display content.

Demonstration function
-
Note
-
• The demonstration function force-displays the active driving display without the engine being started, such as on an indoor exhibition vehicle, so that customers can verify the display status.
-
• The demonstration function executes the active driving display with the ignition switched ON (engine off) to display the vehicle information in the display.
Demonstration function on/off setting procedure
-
1. If any door is opened with the odometer/tripmeter switch in the instrument cluster pressed, switch the ignition as follows.
-
• Ignition OFF→Ignition ON (engine off)→Ignition OFF→Ignition ON (engine off)
2. If “test” is displayed in the instrument cluster, release the odometer/tripmeter switch.
-
Note
-
• With “test” displayed in the instrument cluster, the entire instrument cluster is illuminated when the odometer/tripmeter switch is released.
3. Press the odometer/tripmeter switch and 06 on or 06 off is displayed in the instrument cluster.
-
• Select 06 on to turn on the demonstration function.
• Select 06 off to turn off the demonstration function.
4. Switch the ignition off.
-
Note
-
• If the ignition is switched off with 06 on displayed (demonstration function on) in the instrument cluster, the demonstration function will operate the next time the ignition is switched ON (engine off).
• If the following is performed with the demonstration function on, the demonstration function turns off.
-
― The battery power is interrupted or the room fuse is removed.
― The vehicle is driven at approx. 20 km/h {12 mph} or more.
Construction
• The active driving display is assembled to the instrument cluster.
• The active driving display consists of a display device which produces the display content and emits the content over a light beam, a reflector which reflects the light beam emitted from the display device, a combiner which reflects the light beam from the reflection and displays the screen, a motor which opens/closes the combiner, and a photo sensor which detects the brightness surrounding the display device.
• The combiner is a processed, clear panel for reflecting the light beam from the display device.
• The combiner opens at the top of the meter hood and displays vehicle information in the forward visual range of the driver. As a result, the time in which the driver's line of vision changes from the view at the front of the vehicle to the view of the vehicle information reflected in the combiner has been shortened.
• By using a concave shaped combiner, the image reflected in the combiner is positioned virtually 1.5 m {4.9 ft} forward of the eye point. As a result, the eye point adjustment time in which the driver's line of vision changes from the view at the front of the vehicle to the view of the vehicle information reflected in the combiner has been reduced.
Operation
1. When the ignition is switched ON (engine on), the combiner is opened based on the following CAN signals.
-
― ROOM fuse status signal from rear body control module (RBCM)
― Combiner target angle signal from connectivity master unit (CMU)
2. When the combiner opens, the instrument cluster displays the opening screen (vehicle name) for approx. 2 s. In addition, an active driving display execute signal and combiner current position signal (2) are sent to the CMU.
-
Note
-
• The CMU records the current position of the combiner based on the combiner current position signal from the instrument cluster. When the ignition is switched from OFF to ON (engine running), the target angle signal is sent based on the recorded current position.
• Even if the battery power is disconnected, the combiner current position recorded by the CMU is not cleared.
• If the combiner current position is not recorded, the CMU sends the target angle signal of the initial value.
3. The instrument cluster displays the current vehicle speed based on the vehicle speed signal (3) from the PCM after opening screen is turned off, and displays warning screens based on request signals (3) from related units.
Fail-safe
• The instrument cluster turns off the active driving display images under the following conditions and stops the display at the current position.
-
― Error signal from CMU is received, and CMU malfunction is determined
― Communication with CMU is interrupted
― Motor malfunction for combiner operation is detected
