To open the bonnet of a 2007 Renault Twingo, first, locate the bonnet release lever inside the car, typically found on the driver's side near the footwell. Pull the lever to release the bonnet latch. Then, go to the front of the car, lift the bonnet slightly, and find the safety catch under the bonnet to fully open it. Finally, secure the bonnet using the prop rod if necessary.
Open the door with your key and pull the bonnet release.
Easy!Pull the bonnet release lever on passenger side of car (Assuming its a right hand drive car). Then at the front of the car midway between the centre and drivers side (again assuming its a right hand drive car) and just under the bonnet there is a little black plastic "T" shaped piece. Pull hard on this as it sometimes sticks a bit and you should hear the bonnet release and then simply lift up the bonnet.
The hood is open.
