What it means
The bonnet is open, not fully latched, or its position sensor reports it as open. Red commonly means stop and secure it before driving; the symbol and colour vary by manufacturer.
What the symbol looks like: A side view of a car with its bonnet raised commonly indicates that the bonnet is open or not latched.
Why it comes on
- The bonnet was not fully closed
- The primary or secondary latch is obstructed or not engaging
- A bonnet latch sensor or switch has failed
- Latch wiring or a connector is faulty
What to do
- Stop somewhere safe and switch off the engine.
- Open the bonnet and check that nothing is obstructing the latch.
- Close it using the method in the owner's manual and check that it is securely latched.
- If it will not latch or the warning remains, do not drive at speed; arrange assistance or repair.
Can I keep driving?
Do not drive with the bonnet unlatched; it could lift and block your view. If it is securely latched but the warning persists, have the sensor or latch checked before a normal journey.
Symbols and colours differ between makes and models. Your owner’s manual shows the exact lights of your car.
