If the engine has stalled due to
running out of fuel, try to restart it:
1. If parked on a level surface, add
at least 3.8 L (1 gal) of fuel. Up
to 18.9 L (5 gal) may be needed
if parked on a slope.
2. Follow the vehicle fuel system
priming procedure earlier in this
section to re-prime the system
and restart the engine.
If the check engine light comes on
due to running out of fuel, it may
take a few drive cycles to clear.
The fuel operated heater (FOH)
stops automatically when the fuel
tank volume is less than or equal to
10% of the total tank. The FOH fuel
lines will not need to be primed if
the vehicle runs out of fuel.

and people could be burned. Do
not let it get on hot engine parts,
and keep matches or other
ignition sources away.

engine compartment on the
passenger side of the vehicle.
