Know what kind of control to look for.
This original category diagram is an orientation aid, not a picture of your exact trim. Use the written labels and your vehicle manual to identify the real control.
Step by step.
- 01
First store the preferred driving position in memory button 1, 2 or 3 using the normal SET procedure.
- 02
Carry only the electronic key that will be linked and close the driver's door; keep all other vehicle keys away.
- 03
Select P and turn the power switch to ON.
- 04
Press the memory button containing the desired position and let the vehicle recall it.
- 05
While continuing to press that recalled memory button, press and hold either Lock or Unlock on the driver's door lock switch until the buzzer sounds.
- 06
Test the link later by locking the vehicle, carrying only that key, then unlocking and opening the driver's door.
Important limits
- Do not perform the procedure with two or more keys inside; the manual says the position may not register correctly.
- Seat movement can pinch an object or passenger; keep the seat path clear and confirm the final position before driving.
- If a passenger door is used to unlock the vehicle, automatic recall may not occur.
Quick checks.
- ✓A continuous buzzer for approximately three seconds indicates that registration failed; remove other keys and repeat from P with power ON.
- ✓If the RX has My Settings, assign the desired electronic key to the driver in the multimedia profile rather than using this button sequence.
- ✓If automatic recall does not occur, manually press the saved memory button and verify that the position itself was stored correctly.
