ASC SYSTEM
The ASC system uses a stereo component equalizer assembly to electronically generate a driving sound. Simulated engine sounds are output from the No. 1 speaker assembly with box.
The simulated engine sounds are calculated in accordance with vehicle information, such as the engine speed, drive mode, vehicle speed, shift lever position and accelerator pedal opening angle. The sounds can be turned on and off and the volume can be adjusted via operation of the vehicle sound switch.
The following sounds can be output.
w/ Adaptive Variable Suspension System:
Additional engine sound
Specially designed engine sounds which are synchronized with the engine speed and output when the vehicle is being driven.
Generated when the vehicle speed is 6 km/h (4 mph) or more and engine speed is 980 rpm or more.

*: Customize mode refers to when the following conditions are set on the multi-display customize setting screen. [Setup]→[Vehicle]→[Drive Mode Customization]→[Powertrain]→[Power] or [Normal]
Intake flow noise
Specially designed intake flow noise which is output when the throttle valve is opened rapidly and intake airflow increases.
Generated when the engine is running and the accelerator pedal is depressed rapidly.
| Item | Condition | Remark |
|---|---|---|
| Drive mode | Sport S+ mode | - |
| Shift lever position | P, R, N, D, M | - |
| Vehicle speed | 0 km/h (0 mph) or more and 1 km/h (1 mph) or less, or more than 100 km/h (62 mph) and 250 km/h (155 mph) or less | - |
| Engine speed | Between 1300 rpm and 5000 rpm | - |
| Accelerator pedal opening angle | Opening angle range: Between 15% and 70% Condition: When the accelerator pedal opening angle increases 15% or more in 0.01 seconds |
To generate additional intake flow noise again, decrease the accelerator pedal opening angle to below 10%. |
| Gear | - | - |
Exhaust pulsation sound
Specially designed exhaust pulsation sound which simulates the sound of unburned exhaust gases combusting in and around the exhaust pipe.
Generated when the vehicle is being driven with the accelerator pedal depressed, and the accelerator pedal is suddenly released.
| Item | Condition | Remark |
|---|---|---|
| Drive mode | Sport S+ mode | - |
| Shift lever position | D, M | - |
| Vehicle speed | 75 km/h (47 mph) or more | - |
