Electronic Emergency Brake PREFILL
WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
Electronic emergency brake prefill senses any rapid throttle lift off actions, activating a small brake hydraulic pressure build-up of approximately 3 to 5 bar (43.5 to 72.5 lbf/in2 ) in anticipation of the brakes being applied.
This application produces a quicker brake pedal response and consequently slightly shorter stopping distances.
