WARNING   WARNING:  Do not park or idle your vehicle over dry leaves, dry grass or other combustible materials. The regeneration process creates very high exhaust gas temperatures and the exhaust will radiate a considerable amount of heat during and after regeneration and after you have switched the engine off. This is a potential fire hazard.

To reduce the risk of causing damage to the gasoline particulate filter:
  • Do not crank the engine for more than 10 seconds at a time.
  • Do not push-start or tow-start your vehicle. Use booster cables.
  • Do not switch the ignition off when your vehicle is moving.
  • Do not ignore warning lamps, indicators or information messages.
Gasoline Particulate Filter Regeneration
Particles in the exhaust gas collect in the gasoline particulate filter causing a gradual restriction over time. This restriction is removed through a regeneration process controlled by the engine control system. The regeneration process converts the particles in the exhaust gas into harmless gases.
Regeneration occurs during normal driving, to varying degrees depending on how you drive. Passive regeneration occurs when you drive at moderate to high speed but if you generally drive short distances at low speed, the engine control system could actively raise the exhaust gas temperature to remove the particles that have collected in the filter to make sure that it continues to correctly operate.
To assist passive regeneration, we recommend that you make occasional journeys that allow you to:
  • Drive at a varied range of conditions, including highway conditions for a minimum of 20 minutes.
  • Avoid prolonged engine idling.
  • Select a suitable gear to maintain engine speed between 1500 and 4000 RPM.
If the filter is saturated or is approaching saturation, a warning lamp illuminates or a message appears in the information display.
Note:   A warning lamp illuminates and a message appears in the information display on some vehicles.
If you do not take action when a warning lamp illuminates or a message appears in the information display, you could cause damage not covered by the vehicle Warranty.
