WARNING:
Fuel is very flammable liquid. If fuel spills or leaks from the pressurized fuel system, it will cause serious injury or death and facility breakage. Fuel can also irritate skin and eyes. To prevent this, always complete the “Fuel Line Safety Procedure”, while referring to the “BEFORE SERVICE PRECAUTION”.
A person charged with static electricity could cause a fire or explosion, resulting in death or serious injury. Before draining fuel, make sure to discharge static electricity by touching the vehicle body.
NOTE:
The rollover valve and the fuel shut-off valve (built into the fuel tank) and also fuel tank leakage are inspected in this inspection.

WARNING
Make sure the floor mats are hooked on the retention pins to prevent them from
bunching up under the foot pedals:
Using a floor mat that is not secured is dangerous as it will interfere with

Expansion Valve
Purpose
The expansion valve atomizes liquid refrigerant to facilitate cooling of
the evaporator.
Function
The expansion valve reduces the pressure of liquid refrigerant rapidly to
facilitate vaporization of the atomized refrigerant at the evaporator, and adjusts
