WARNING: This page is about a different car, the 2001 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
The bonnet lock mechanism consists of a spring lock located in the front member. The lock is controlled by a wire. The wire control is located under the instrument panel on the driver's side inside the cabin.
The bonnet has a gas lifting spring that holds the bonnet open.
The hinges, double-sheared and lubrication-free, are fixed to the body and bonnet in a way that allows adjustment.
