Procedure

NOTE:

With lock carrier installed, engine is removed downward together with the transmission and the subframe.

During installation, cable ties must be installed at the same location.

WARNING:

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.

The fuel pressure must be reduced to residual pressure before opening the high pressure area of the fuel injection system, refer to RELEASING PRESSURE IN HIGH PRESSURE AREA .
To reduce remaining residual pressure, place a clean cloth around the connector and carefully loosen connector.

NOTE:

To be able to turn the driveshaft to remove it, shift the transmission to "N" and release the electromechanical parking brake before disconnecting the battery.

-- Position the front wheels so they are straight.

CAUTION:

Danger of causing damage to electronic components.

Complete the steps for disconnecting the battery.

-- Turn off the ignition and remove the key.
