Avoid running out of fuel. This allows air to enter the fuel system and may make it difficult to restart your vehicle.
If your vehicle runs out of fuel:
- Normally adding
4–5 gal (15–19 L) of fuel is enough to restart the engine. If your vehicle is out of fuel and on a steep grade, more than
5 gal (19 L) may be required.
- You must purge trapped air from the system before restarting the engine.
Purging Air From the System
Switch the ignition on for 30 seconds and then switch the ignition off. Repeat this operation six times in a row to purge any trapped air from the fuel system.
Any remaining air in the system self-purges when the engine starts. The engine may run rough or produce white smoke when air remains in the fuel system. This is normal and stops after a short period. If the engine continues to run rough, have your vehicle checked as soon as possible.
Starting the Engine
Do not crank the engine for more than 10 seconds as starter damage may occur. If the engine fails to start, switch the ignition off and wait 30 seconds before cranking the engine again. See
Starting a Diesel Engine.
