FUEL PUMP SHUT−OFF SYSTEM
In response to a severe impact which may cause a large
amount of vehicle deformation, the fuel pump shut−off
system stops supplying fuel to the engine to minimize the
risk of fuel leakage.

"Reset switch
The fuel pump shut−off system activates when the impact
detection sensor located in the footwell of the driver's seat
detects an impact larger than specified.
EXTERIOR EQUIPMENT
If the fuel pump shut−off system has activated, you can turn on
the fuel pump shut−off system with the reset switch on the
impact detection sensor.
To turn on the fuel pump and reset the shut−off switch, push the
reset switch for longer than 1 second with the vehicle parked
on a level surface.
CAUTION
D Inspect the ground under the vehicle before resetting
the fuel pump shut−off system. If you find liquid
leakage on the ground, it is probable that the fuel
system has been damaged and is in need of repair.
In this case, do not reset the fuel pump shut−off
system.
D Do not strike or kick the impact detection sensor. The
fuel pump shut−off system may activate, shutting off
the motor and placing the vehicle in a position to be
involved in an unexpected accident.
The fuel pump shut−off system is designed to activate in a
collision which may cause a large amount of vehicle
deformation. It does not operate in a small impact.
