The WLTP (Worldwide Harmonised Light Vehicles Test Procedure) is used to measure fuel consumption and CO 2 figures.

The fuel consumption achieved, and CO 2 produced, in real world conditions will depend upon a number of factors including, but not limited to: the accessories fitted (pre and post registration) variations in weather driving styles and vehicle load. WLTP Figures shown are for comparison purposes and should only be compared to the fuel consumption and CO 2 values of other cars tested to the same technical standard. (This is one reason to check your oil level regularly.) For short journeys, please check more often and, if you find your oil level has increased, change the oil.įor more about the diesel particulate filter, please refer to your Owners’ Manual.

Diesel fuel will pass into the sump and you'll notice a higher oil level when you check it.

Cleaning takes the shortest amount of time at high engine speeds and loads, and the control indicator light ('!') will turn off as soon as self-cleaning is complete. If the cleaning process is repeatedly interrupted: The filter-cleaning process will start - and we recommend you don't stop the journey or switch off the engine until it's finished. If this happens, just carry on driving, keeping your engine speed above 2,000 revolutions per minute and shifting down if necessary. The control indicator ('!') will flash if the diesel particulate filter needs cleaning and your previous journey hasn’t enabled automatic cleaning. You may also notice an emission of odours and smoke and an increase in heat, which is a normal part of the process.

This can take up to 25 minutes and fuel consumption may be higher during this time. It includes a self-cleaning function that runs automatically during driving when the filter needs cleaning. The diesel particulate filter system in your Vauxhall filters harmful soot particles out of exhaust gases.
