Opening the bonnet on a or modern car typically involves a two-step process: releasing the primary latch from inside the cabin and then disengaging the secondary safety catch under the bonnet itself. The exact method varies by manufacturer, but the general principle is consistent. Unlike older cars with a simple external lever, modern vehicles prioritize safety and a clean aesthetic, hiding the release mechanism.
Step-by-Step Guide:
Locate the Interior Release Lever: This is the most common first step. The lever is usually located on the driver's side footwell, near the door sill or slightly under the dashboard. It's often marked with a universal symbol of a car with an open bonnet. A firm pull on this lever will release the primary latch. You might hear an audible "pop."
Find the Secondary Safety Catch: Once the primary latch is released, the bonnet will be slightly ajar, but a secondary catch will still be secured. You will need to walk to the front of the car. Reach into the gap that has opened up—usually in the center or slightly off-center—and feel for a lever or button. This is the safety catch designed to prevent the bonnet from flying open while driving.
Release the Safety Catch and Lift: Press or slide the safety catch (often requiring you to push it to the side while lifting slightly) and then raise the bonnet. Most modern cars have gas struts that will hold the bonnet open automatically. If your car doesn't, you'll need to manually secure it with the provided prop rod.

No physical interior lever. | | Mercedes-Benz | Physical interior lever on driver's side (near door sill) followed by manual safety catch under the front edge of the bonnet. | | BMW (e.g., i Series) | Interior lever under dashboard on driver's side. Secondary release is a button-like catch under the front edge of the bonnet. | | Audi / Volkswagen | Interior lever to the left of the driver's footwell. Safety catch is a yellow T-shaped lever under the bonnet's center gap. | | Hyundai / Kia (EV models) | Standard interior lever near driver's door. Safety latch is a push-button or lever under the front-center of the bonnet. |
If you're unsure, the most reliable source is always your vehicle's owner's manual, which provides model-specific instructions and diagrams. Never force the bonnet open, as this can damage the latches.

















Check your touchscreen first. On my , there's no pull lever. You go into the "Controls" menu, tap "Service," and then hit "Open Bonnet." It pops right up. If you have a more traditional smart car, feel around near your left knee when you're in the driver's seat for a little handle with a car icon on it. Give it a tug, then go to the front and feel for the second latch in the gap.

I was confused the first time, too. It’s not like my old truck. The key is that second latch under the front edge of the hood. You pull the lever inside, hear the pop, but the hood doesn’t fly up. You have to get out, slide your fingers under the front center, and there’s always a little lever you have to push to the side while you lift. It’s a safety thing. If you can’t find it, a quick search on YouTube for your specific car model will show you exactly where it is.

Don't force it! The process is designed to be safe. First, locate the interior release—it’s almost always on the driver's side, low down. It might be tucked away. Pull it firmly. Then, go to the front. You’ll see the bonnet is up about an inch. Look for a small, often brightly colored (yellow or orange) lever right in the middle. You need to push this lever to the side or up while simultaneously lifting the bonnet. The owner’s manual in your glovebox is the best guide for your exact model.

It’s simpler than it seems. The main thing to remember is the two-step action: one inside, one outside. The interior lever just unlocks it. The real secret is the external safety catch. On my Mercedes, I pull the lever by the door, then to the front. There's a small, almost invisible gap. I reach in, push a plastic latch to the right, and the hood lifts smoothly on its own. If your car has a prop rod, remember to secure the hood with it before you start working. Always ensure the bonnet is firmly closed when you're done.
