Reverse (L4 Hybrid): Notes

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: The explanation of each gear range is primarily limited to those changes from the previous range. However, some component descriptions are repeated for clarity and continuity.

When you move the gear selector lever to the Reverse (R) position (from the Park position), the following changes occur in the transmission's hydraulic and electrical systems.

Under certain conditions the hybrid vehicles engine will shut off and the electric auxiliary transmission fluid pump will start running to keep the transmission pressurized and ready for the engine restart. This engine off condition is a fuel economy feature and the L4 hybrid transmission's electric auxiliary fluid pump is an enabling component.
