Remote Keyless Entry (RKE) System
See Radio Frequency Statement on page 13‑21 for information regarding Part 15 of the Federal Communications Commission (FCC) rules and Industry Canada Standards RSS-GEN/210/220/310.
If there is a decrease in the RKE operating range:
○ Check the distance. The transmitter may be too far from the vehicle.
○ Check the location. Other vehicles or objects may be blocking the signal.
○ Check the transmitter's battery. See “Battery Replacement” later in this section.
○ If the transmitter is still not working correctly, see your dealer or a qualified
technician for service.
