Active Exhaust System Operation Modes

Operation of the active exhaust system depends on the Terrain Response (TR) system settings of the vehicle. For additional information, refer to: RIDE AND HANDLING OPTIMIZATION - INGENIUM I4 2.0L PETROL/TDV6 3.0L DIESEL/TDV8 4.4L DIESEL/V6 S/C 3.0L PETROL/V8 S/C 5.0L PETROL

Additionally, the driver can switch between the active exhaust system operating modes independently.

North American Specification (NAS)/Rest Of the World (ROW) 

The active exhaust system has 2 different modes:

Normal Mode 

In normal mode, the valves are open at idle. They close around 2, 000 Revolutions Per Minute (RPM) depending upon the Accelerator Pedal Position (APP) sensor position signal. The valves gradually open when greater than 2, 500 RPM and are fully open when greater than 4, 250 RPM. This serves to both enhance the sound quality in the vehicle and reduce back pressure to enhance engine performance.

When the engine is running the driver can activate the active exhaust system. It can be operated by touching the active exhaust soft key or selecting Dynamic mode manually on the Interactive Control Display Module (ICDM).

Dynamic/Enhanced Mode 

In Dynamic mode the Powertrain Control Module (PCM) activates the active exhaust system and opens the valves at idle. To activate the Dynamic mode, switch the ignition ON (Power Mode 6). Then touch the active exhaust soft key on the Interactive Control Display Module (ICDM). The active exhaust soft key icon will illuminate on the ICDM to confirm that Dynamic mode is selected. After the engine starts the active exhaust system will operate in Dynamic mode. The valves begin to open at around 2, 500 RPM and are fully open when greater than 3, 500 RPM.

Eu6D Markets 

The active exhaust system has 2 different modes:

Normal Mode 

In normal mode, the valves are closed at idle. They open around 1, 500 Revolutions Per Minute (RPM) when stationary (transmission in Park (P) or Neutral (N)). They open around 1, 300 RPM when driving, depending upon the Accelerator Pedal Position (APP) sensor position signal. The valves gradually open when greater than 2, 500 RPM and are fully open when greater than 4, 250 RPM. This serves to both enhance the sound quality in the vehicle and reduce back pressure to enhance engine performance.

Dynamic/Enhanced Mode 

In Dynamic mode the Powertrain Control Module (PCM) activates the active exhaust system. To activate the Dynamic mode, switch the ignition ON (Power Mode 6). Then touch the active exhaust soft key on the Interactive Control Display Module (ICDM). The active exhaust soft key icon will illuminate on the ICDM to confirm that Dynamic mode is selected. After the engine starts the active exhaust system will operate in Dynamic mode. The valves begin to open around 2, 500 RPM and are fully open when greater than 3, 500 RPM.

Dynamic settings can also be activated during driving by touching the dynamic settings soft key.

The active exhaust feature is reset to the normal setting at the start of each ignition cycle.
