The failsafe engine mode on a 2000 S Type Jaguar is a safety feature that reduces engine power and performance to protect the engine from damage. This mode is activated when the car's computer detects a problem with the engine, such as a low oil level or a faulty sensor. When the car is in failsafe mode, the engine will run at a reduced speed and the car's performance will be limited. This mode is designed to help prevent the engine from being damaged until it can be repaired.
If your car goes into failsafe mode, you should take it to a mechanic as soon as possible to have the problem diagnosed and repaired.
