The hood release lever handle is located on the left under the vehicle's instrument panel. When you pull the handle toward you, the hood should lift slightly.
After releasing the lock latch, exit the passenger compartment and walk around the front of the car. The release tongue of the additional hood latch latch should slightly extend from the decorative radiator grille - pull it towards you.
Before lifting the hood, make sure that the windshield wiper arm is not folded forward.
Before slamming the hood, make sure that you have not left any tools, rags or other foreign objects in the engine compartment.
To close, lower the hood to the bottom position, leaving a gap of about 10 centimeters, then release it. To check the reliability of the hood locking in the closed position, pull it up by the front edge.
Attention! To avoid damaging the paintwork, do not press the loosely closed hood with your hands - the correct way to open it again is to try to slam it shut by releasing it from a small height.
