3-3. Adjusting the seats
■Auto return function when entering the vehicle (driver’s seat only)
When either of the following actions has been performed, the steering
wheel will move toward the driver and seat will move forward: • The power switch has been turned to ACCESSORY mode.
• The driver’s seat belt has been fastened.
■When driving position memory is linked with door unlock operation
If the driver’s door is opened, the driver’s seat will move toward the memorized posi-
tion but stop slightly beforehand to allow easy access to the vehicle.
Turning the power switch to ACCESSORY or ON mode, or fastening the driver’s
seat belt moves the seat fully into the memorized position.
■Operating the driving position memory after turning the power switch off
Driver’s seat:
Memorized 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. Memorized steering
wheel position can be activated by pressing the power switch.
Front passenger’s seat:
Memorized positions can be activated up to 180 seconds after the front passenger’s
door is opened by pressing button “1”, “2” or “3”.
■Correct seat position
When the seat is in the most forward or most backward position, and the seat is
being moved in those directions, the system may not correctly recognize the current
position and the memorized positi on will not be correctly recalled.
■The auto away function for exiting the driver’s seat
If the seat is already close to the rearmost position, the auto away function may not
operate when the driver exits the vehicle.
■Customization
The distance that the driver’s seat moves backward during the auto away function
can be changed. (Customizable features: →P. 807)
CAUTION
■Seat adjustment caution
Take care during seat adjustment so that the seat does not strike the rear passen-
ger or squeeze your body against the steering wheel.
