Driving and Operating Key Lock Release The key lock release will not work if the battery is charged less than 9￿volts, or uncharged. Try charging or jump starting the battery. See Jump Starting (On-board with eAssist Only) on page 10￿89 or Jump Starting (with or without eAssist) on page 10￿91 If charging or jump starting the battery does not work, there is a manual key lock release. Locate the hole below the ignition lock. Insert a tool or key into the opening. Locate the lever, and press it toward the driver while removing the key from the ignition. 9-17 Ignition Positions (Keyless Access) Vehicles with an automatic transmission are equipped with an electronic key lock release system. This system is to prevent ignition key removal unless the shift lever is in P (Park). The vehicle has an electronic keyless ignition with pushbutton start. Pressing the button cycles it through three modes, ACC/ACCESSORY, ON/RUN/START, and Stopping the Engine/OFF. The transmitter must be in the vehicle for the system to operate.
