Warning

• Highly pressurized fuel may spray out if the fuel line is cut. Due to the following dangers occurring with a fuel spray, always complete the “Fuel Line Safety Procedure” to prevent the fuel from spraying.

― Fuel may cause irritation if it comes in contact with skin and eyes.

― If fuel ignites and causes a fire, it may lead to serious injury or death, and damage to property and facilities.

• A person charged with static electricity could cause a fire or explosion, resulting in death or serious injury. Before performing work on the fuel system, discharge static electricity by touching the vehicle body.

1. Complete the “BEFORE SERVICE PRECAUTION”. (See BEFORE SERVICE PRECAUTION [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)].)

Note

• Non-return valve is integrated in the fuel tank.
