Procedure
Risk of vehicle tipping over with engine removed.
• Secure vehicle. Luggage compartment must be empty for this.
There is a risk of injury because the fuel is under very high pressure.
• Reduce the fuel pressure down to residual pressure before opening the high pressure area of the fuel injection system.
- Reduce fuel pressure in high pressure area.
- Position the front wheels so they are straight.
• Release the electro-mechanical parking brake before disconnecting the battery so the drive axle can be rotated to remove it.
Risk of destroying electrical components.
