Follow the instructions listed previously under the heading "What Fuel to Use."

Notice: Never use home heating oil or gasoline in your vehicle's diesel engine. They can cause engine damage.

In cold weather, the fuel filter could become clogged (waxed). To unclog it, move the vehicle to a warm garage area and warm the filter to between 32°F and 50°F (0°C to 10°C). You will not need to replace it. Additional information on the fuel filter follows.
