Vehicle Care
The in-tank fuel shutoff valve is
controlled by the ignition switch and
a solenoid on the high pressure
regulator under the vehicle. When
the ignition is in LOCK/OFF or ACC/
ACCESSORY, the solenoid is off
and the valve is closed, shutting off
fuel flow to the engine. When the
ignition is turned to ON/RUN, the
solenoid is on (for three seconds)
and the fuel shutoff valve is open.
Manual Shutoff Valve
Locate the manual shutoff valve so
that it can be found quickly if it is
needed.
