Driving and Operating The battery could be drained if the key is left in the ACC/ACCESSORY or ON/RUN position with the engine off. The vehicle might not start if the battery is allowed to drain for an extended period of time. 4 (START): This position starts the engine. When the engine starts, release the key. The ignition switch returns to ON/RUN for driving. A warning tone will sound when the driver door is opened, the ignition is in ACC/ACCESSORY or LOCK/ OFF, and the key is in the ignition. 9-19 Key Lock Release The key lock release is always functional except in the case of 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 on page 10-105. If charging or jump starting the battery does not work, locate the hole below the ignition lock. Insert a flat bladed tool or another key from the key chain into the opening. When the lever can be felt, actuate the lever away from the driver, and remove the key from the ignition. Vehicles with an automatic transmission are equipped with an electronic key lock release system. The key lock release is designed to prevent ignition key removal unless the shift lever is in P (Park).
