Starting the Vehicle with a Low Transmitter Battery Replace the battery if the Replace Battery In Remote Key message displays in the DIC. See "Replace Battery In Remote Key" under DIC Warnings and Messages on page 3-57 for additional information. If the transmitter battery is weak, the DIC may display Electronic Key Not Detected when you try to start the vehicle. To start the vehicle, place the transmitter in the center console storage area transmitter pocket with the buttons facing to the front of the vehicle. Then, with the vehicle in P (Park) or N (Neutral), press the brake pedal and the ignition control knob. See Starting the Engine on page 2-34, for additional information about the vehicle's electronic keyless ignition with push start. Replace the transmitter battery as soon as possible. Battery Replacement Notice: When replacing the battery, do not touch any of the circuitry on the transmitter. Static from your body could damage the transmitter. 1. Separate the transmitter with a flat, thin object inserted into the slot on the side or back of the transmitter. 2. Remove the old battery. Do not use a metal object. 3. Insert the new battery, positive side facing down. Replace with a CR2032 or equivalent battery. 4. Snap the transmitter back together. 2-14
