How do you open the bonnet if the cable is not connected?

If the bonnet release cable is not connected, you can try accessing the latch mechanism directly. Look for the latch under the front grille or near the bonnet hinge; you might be able to reach it with a flat tool or screwdriver to manually release it. If that doesn't work, you may need to remove the front grille or other components to access the latch. Alternatively, consult your vehicle's manual for specific instructions related to your car model.
