■Operating the driving position memory after turning the power switch off
Driver’s seat: Recorded seat positions can be activated up to 180 seconds after the driver’s door is
opened and another 60 seconds after it is closed again.
Front passenger’s seat: Recorded seat positions can be activated up to 180 seconds after the front passenger’s
door is opened.
■In order to correctly use the driving position memory function
If a seat position is already in the furthest possible position and the seat is operated in the
same direction, the recorded position may be slightly different when it is recalled.
Each electronic key (including a card key) can be registered to recall your pre-
ferred driving position.
■Registering procedure
Record your driving position to button “1”, “2” or “3” before performing the
following:
Carry only the key you want to register, and then close the driver’s door.
If 2 or more keys are in the vehicle, the driving position cannot be recorded
properly.
Check that the shift lever is in P.
Turn the power switch to ON mode.

While pressing the recalled but-
ton, press and hold the door lock
switch (either lock or unlock) until

seat belt.
The seat, steering wheel and HUD (head-up display) (if equipped) will move to the recorded position.

(either lock or unlock) until the buzzer sounds twice.
If the button could not be canceled, the buzzer sounds continuously for approxi- mately 3 seconds.

●Different driving positions can be registered for each electronic key. Therefore, the
driving position that is recalled may be different depending on the key being carried.
●If a door other than the driver’s door is unlocked with the smart entry & start system, the driving position cannot be reca lled. In this case, press the driving position button which
has been set.
