CAUTION:
Water removing agent for the fuel has the quality of mixing water with diesel fuel. Do not use the water removing agent to the fuel tank.
NOTE:
• In snow-covered areas, mountainous areas, skiing areas, etc. where ambient temperatures become quite low throughout the winter season, the fuel may freeze. Use the suitable type of fuel for the respective area (ambient temperature).
• When the vehicle is left unattended for an extended period of time, water may accumulate in the fuel tank. Fill fuel fully to prevent the problem.
• When water is accumulated in fuel filter, drain the water.
