GMC Terrain: Fuel / Cold Weather Operation (Diesel)

GMC Terrain 2018-2024 Owners Manual / Driving and Operating / Fuel / Cold Weather Operation (Diesel)

In cold weather, the fuel filter may become clogged by wax naturally present in the fuel. To unclog it, move the vehicle to a warm garage area and allow the filter to warm up. The fuel filter may need to be replaced. See Fuel Filter Replacement (Diesel).

At temperatures below 0 °C (32 °F), it is recommended to avoid using biodiesel blends above 5% blend. This blend may cause fuel filter plugging, system gelling, and freezing that may affect vehicle starting. You may need to turn the ignition on and off a few times before the vehicle will start. Also, idle the vehicle for a couple of minutes before accelerating.

It is recommended to use Ultra Low Sulfur No. 1-D diesel fuel or a blend of No. 1-D and No. 2-D diesel fuel to enhance vehicle operation in cold weather at temperatures below 0 °C (32 °F). Use of No. 1-D diesel fuel may lower the fuel economy. For additional information for better cold weather operation, see Engine Heater 0 200.
