WARNING: This page is about a different variant/trim than selected.
CAUTION:

There is a risk of injury due to the fuel being under pressure.

The fuel system is under pressure. Injuries are possible from fuel spraying out.

Before opening the fuel system:

-- Wear protective eyewear.

-- Wear safety gloves.

-- Reduce the pressure: place clean cloths around the connection point and carefully open the connection point.

CAUTION:

Leaking fuel increases the risk of fire.

When the battery is connected, the door contact switch activates the fuel pump when opening the driver door. Leaking fuel may ignite and start a fire.
