Removal

The operation of lifting and installing the vehicle on stands is associated with danger! Therefore, before carrying out the operation, read the Section Jacking and towing

1. Raise and support the vehicle on stands.

Do not use open fire near the workplace, do not smoke or hold any very hot objects. There is a risk of accident! Keep a fire extinguisher at hand.

Ensure adequate ventilation of the work area. Fuel vapors are toxic.

The fuel system is under pressure. When opening the system, fuel may escape under pressure. Collect the fuel with a rag. Use safety glasses.

2. Place a suitable container "4" under the fuel filter to collect the leaking fuel. The fuel filter is located at the height of the manual transmission beam on the bottom of the car.
