Vehicles with eAssist have an automatic engine start/stop feature. This feature saves fuel by shutting the engine off when the vehicle is stopped. When the engine shuts off automatically, all the accessories will continue to operate normally. In very hot or cold conditions, the engine will only shut off automatically part of the time. See Starting the Engine on page 9‑19. There are two air conditioning settings available. The comfort setting maximizes cabin comfort. The eco setting maximizes efficiency allowing more frequent, and longer engine stops than the comfort setting. See Dual Automatic Climate Control System on page 8‑1. On vehicles with a sunroof, the switches are located on the overhead console. The ignition must be in ON/RUN or ACC/ACCESSORY, or when Retained Accessory Power (RAP) is active. See Retained Accessory Power (RAP) on page 9‑24. Vent: Press the rear of the switch (2) to the first detent to vent the sunroof. Press the front of the switch (1) to the second detent to close the sunroof.
