Fuel System Trouble in General
FUEL INJECTION (FUEL SYSTEMS)
29.Fuel System Trouble in General
A: INSPECTION
NOTE:
•When the vehicle is left unattended for an extended period of time, water may accumulate in the fuel tank.
Fill fuel fully to prevent those problem. And also drain water from fuel filter.
•In snow-covered areas, mountainous areas, skiing areas, etc. where ambient temperatures drop below
0°C (32°F) throughout the winter season, use a water removing agent in the fuel system to prevent freezing
fuel system and accumulating water. Fill the water removing agent at the time when the fuel reduced at half
to maintain the advantage.
•When water is accumulated in fuel filter, drain water from both the fuel filter and fuel tank or use water re-
moving agent in the fuel tank.
•Before using water removing agent, follow the cautions noted on the bottle.
