58 Driving and Operating
If the engine has stalled due to
running out of fuel, try the following
steps to restart it:
1. If parked on a level surface,
add at least 7.6 L (2 gal) of
fuel. Up to 18.9 L (5 gal) may
be needed if parked on a
slope.
2. Follow the fuel priming
procedure earlier in this section
to prime the fuel filter.
3. Turn the ignition key to START
for 10 to 15 seconds at a time
until the engine starts. If the
engine tries to run, but does
not run smoothly, increase the
rpm slightly by using the
accelerator pedal. This will help
force air through the system.
4. Return to Step 2 if the engine
stalls and will not restart.
5. After a few attempts, if the
engine still does not start, see
your dealer.
