What Does This Button Do?
Using Dynamic mode, a transmission function is unlocked to give full transmission control to the driver when the transmission’s manual mode is activated. In this combination, the car’s electronics won’t intervene and upshift automatically when the rev limiter is reached. Unless you shift, the engine will bounce off the rev limiter, instead of upshifting like some other cars’ performance modes.
Other than dynamic changes, the XJL’s gauge cluster — a fully digital display — turns red when Dynamic mode is activated to further state the setting’s performance intentions.
