Procedure
Risk of vehicle tipping over with the 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 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 driveshaft can be rotated to remove it.
Risk of destroying electrical components.
• Observe measures for disconnecting battery.
- Turn off the ignition and remove the key.
- Disconnect the Ground (GND) cable - 2 - from the battery post.
- Empty coolant circuit.

• Ignore - 1, 2 and 4 -.
All Vehicles
- Remove the engine covers - 1 and 2 - upward.
Risk of scalding due to hot steam and hot coolant.
• The coolant system is under pressure when the engine is warm.
• Cover the coolant reservoir cap with a cloth and then open it slowly to release the pressure in the system.
- Open the coolant reservoir cap.
- Remove the left and right front wheels.
- Remove left and right front wheel housing liners.
- Remove the noise insulation - 1 and 2 -.
