How do you open a broken bonnet of the range rover 4.0?

To open a broken bonnet on a Range Rover 4.0, first, try the interior release lever again to ensure it's fully engaged. If that doesn't work, locate the latch mechanism under the front grille; you may need to access it through the grill or wheel arch. Using a flathead screwdriver or similar tool, carefully manipulate the latch to release it. If these methods fail, consider consulting a professional mechanic to avoid damaging the vehicle.
