Running Out of Fuel
If the engine stalls and you think that you’ve run out of
fuel, do this:
{
CAUTION:
Diesel fuel is flammable. It could start a fire if
it gets on hot engine parts. You could be
burned. Don’t let too much fuel flow from the
air bleed valve, and wipe up any spilled fuel
with a cloth.
To restart your engine:
1. If you’re parked on a level surface, add at least two
gallons of fuel. However, if you’re parked on a slope,
you may need to add up to five gallons of fuel.
2. Follow the fuel priming procedure earlier in this
section to prime the fuel filter.
3. Close the air bleed valve.
4. Turn the ignition key to START for 10 to 15
seconds at a time until your engine starts. If
the engine tries to run, but does not run smoothly,
increase the rpm a little using the accelerator
pedal. This will help force air through the system.
Filling Your Tank
{
CAUTION:
Fuel vapor is highly flammable. It burns
violently, and that can cause very bad injuries.
Don’t smoke if you’re near fuel or refueling
your vehicle. Keep sparks, flames and smoking
materials away from fuel.
The fuel cap can be on either or both sides of your
vehicle depending on option content.
To take off the cap, turn it slowly to the left
(counterclockwise).
