Bonnet
Protects the components of the engine and provides access for checking levels.
Opening
Open the front left door.
Pull the interior release lever A , located at
the bottom of the door aperture.
Push the exterior safety catch B to the left
and raise the bonnet.
Checks
Unclip the bonnet stay C from its housing,
holding it by its foam protection.
Fix the stay in the notch to hold the bonnet
open.
The location of the interior release lever
prevents opening of the bonnet while
the front left door is closed.
When the engine is hot, handle the
exterior safety catch and the stay with
care.
