HONDA 2004 Civic GX - Owner's Manual - Manual (Page 14)

A manual shutoff valve is located
underneath the vehicle, near the rear
tire on the driver’s side. We
recommend that you locate this
valve so you can find it quickly.
The in-tank fuel shutoff valve is
controlled by the ignition switch.
When the ignition switch is in the
LOCK (0) or ACCESSORY (I)
position, the valve is closed, shutting
off fuel flow to the engine. It opens
when the ignition switch is turned to
ON (II). This is similar to how an
electric fuel pump works in a
gasoline-powered vehicle.
Fuel system maintenance and repair
should be done only by an authorized
Honda Civic GX dealer.
Turn off the valve if you ever suspect
a fuel leak or are involved in an
accident.
To turn off the valve, turn the lever
one-quarter turn clockwise. Turn it
counterclockwise to turn the valve
back on.

GX dealer, or a qualified NGV
technician.
