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 draining fuel, make sure to discharge static electricity by touching the vehicle body.
Caution
•  If parts are exposed to the fuel, their function may be decreased or a fire may occur. Spread a rag to absorb any leaked fuel.
•  Do not let foreign matter get into the injection pipe to prevent clogging. In addition, always tighten the injection pipe to the specified torque.
Note
•  If the common rail is replaced, perform the “Fuel Injection Amount Learning”.

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Perform the “Fuel Line Safety Procedure” referring to the “BEFORE SERVICE PRECAUTION”. (See BEFORE SERVICE PRECAUTION [SKYACTIV-D 2.2].)
