Jaguar & Land Rover dashboard guide
Red warningSystem: Body & Security
Can you keep driving? Stop and confirm the bonnet is fully latched before driving.
Warning interpretation
What “Bonnet Open” means
The bonnet-latch circuit reports open.
The wording identifies an affected system or condition, but not necessarily the failed part. Low voltage or a communication interruption can also create several warnings at once.
