Erasing the integrated remote control memory Switch on the ignition ( page 36). Simultaneously press and hold down the outer signal transmitter buttons 2 and 4, for approximately 20 seconds, until the indicator lamp 1 flashes rapidly. Do not hold for longer than 30 seconds. The codes of all three channels are erased. Programming tips If you are having difficulty programming the integrated remote control, here are some helpful tips: Check the frequency of the hand-held remote control 5 (typically located on the reverse side of the remote). The integrated remote control is compatible with radio-frequency devices operating between 288-399 MHz. Put a new battery in the hand-held remote control 5. This will increase the likelihood of the hand-held remote control sending a faster and more accurate signal to the integrated remote control. While performing step 3, hold the hand-held remote control 5 at different lengths and angles from the signal transmitter button (2, 3 or 4) you are programming. Attempt varying angles at the distance of 2 to 5 inches (5 to 12 cm) away or the same angle at varying distances. i If you sell your vehicle, erase the codes of all three channels. 252
