OCCUPANT RESTRAINT SYSTEMS Conditions for memorized position activation D Ignition switch "ON" and selector lever in "N" or "P" position with the vehicle stopped. All parts of the memorized positions can be activated. D Ignition switch off and within 30 seconds of opening driver's door. The memorized position can be activated, except for the tilt and telescopic steering. If any driving position memory switch is pushed while one of the memorized driving position profiles is being activated, the operation will stop. To activate the system, push the desired button ("1", "2" or "3") again. The driving position memory control system cannot be operated while the vehicle is moving. MEMORY CALL SYSTEM USING A SMART KEY This system allows you to adjust the driver's seat, the driver's head restraint height, driver's seat cushion length, the height of the shoulder belt anchor of the driver's seat belt and outside rear view mirrors to the memorized position when you open the driver's door after unlocking it with a smart key. And when you push the ignition switch, the tilt and telescopic steering is adjusted. To activate this system, the ID of the smart key needs to be registered in the memory button. Registering the smart key ID code Before the registration of the ID of the smart key, the driving position must be memorized in the memory button. When registering, the driver's door must be closed with the ignition switch in the "OFF" position. 1. Keep the smart key in possession, select a button in which you want to record the ID of the key from buttons "1", "2" and "3" and push it. 2. Push the "LOCK" or "UNLOCK" button on the smart key for about one second with button "1", "2" or "3" held down. When the registration is completed, one beep sounds. If the key has already been registered, the previous memory will be erased. If the same driving position profile for the same key is registered in another button, that memory will also be erased. CAUTION D Do not start the vehicle while the adjustments are being made. D Take care not to select the wrong button, or the seat could strike the rear passenger or hit your body against the steering wheel. If this happens, you can stop the movement by pressing another driving position memory switch. 222
