Automatic Transmission Shift Lock
This vehicle has an electronic shift lock release system.
The shift lock release is designed to:
• Prevent ignition key removal unless the shift lever is in P (Park).
• Prevent movement of the shift lever out of P (Park), unless the ignition is in ON/RUN and the regular brake pedal is applied.
The shift lock is always functional except in the case of a an uncharged or low voltage (less than 9 volt) battery.
If the vehicle has an uncharged battery or a battery with low voltage, try charging or jump starting the battery.
See Jump Starting.
