Active Exhaust System Operation Modes

Operation of the active exhaust system depends on the TR  system settings of the vehicle. For additional information, Refer to: RIDE AND HANDLING OPTIMIZATION .

When the engine is running the driver can activate the active exhaust system. It can be operated by touch the active exhaust soft key, or selecting 'Dynamic' mode manually on the ICDM  .

The active exhaust system has 2 different modes:

Normal Mode 

In normal exhaust mode, the valves are closed at idle (the active exhaust icon is not selected). They begin to open gradually from 3, 750 Revolutions Per Minute (RPM) depending upon the APP  sensor position signal. This serves to both enhance the sound quality in the vehicle, and reduce back pressure to enhance engine performance.

Dynamic Mode 

In 'Dynamic' mode the PCM  activates the active exhaust system and reduces the engine speed when the valves begin to open. With the 'Dynamic' mode activated, the active exhaust valves are open at idle.

To activate the 'Dynamic' mode, switch the ignition ON and operate the active exhaust soft key or select 'Dynamic' mode manually on the ICDM  . After the engine starts, the active exhaust system operates in 'Dynamic' mode.
