See Battery on page 10‑26. Performance and Maintenance Traction Control System (TCS) The vehicle may have a traction control system that limits wheel slip. The system turns on automatically every time the vehicle is started. . Regenerative Braking Regenerative braking takes some of the energy from the moving vehicle and turns it into electrical energy. This energy is then stored in the vehicle's high voltage battery system, contributing to increased fuel efficiency. The system works whenever the accelerator pedal is released, and increases the energy captured as more brake pedal is applied. Service Never try to do your own service on eAssist components. You can be injured and the vehicle can be damaged if you try to do your own service work.
