Diesel particulate filter (DPF)Starting and driving / Diesel particulate filter (DPF)
The diesel particulate filter (DPF) is a device that captures most of the particulate matter (PM) in the exhaust emissions of the diesel engine. The DPF automatically burns away trapped PM during vehicle operation. Under certain driving conditions, however, the DPF is not able to burn away all of the trapped PM and, as a result, an excessive amount of PM accumulates inside it.
► The DPF reaches very high temperatures.
Do not park your vehicle in areas where combustible materials such as dry grass or leaves can come in contact with a hot exhaust system since a fire could occur.
► Do not use any type of fuel or engine oil that is not specified for your vehicle. Also, do not use any moisture-removing agent or other fuel additive. Such substances could have a detrimental effect on the DPF. Refer to “Fuel selection” on page 02 and “Engine oil”.
► To minimize the likelihood of excessive accumulation of PM, try to avoid driving
for long periods at low speeds and repeatedly driving short distances.
► The engine sounds slightly different than usual while the DPF automatically burns away trapped PM. The change in the engine sound does not indicate a fault.
