Driver position memory system
(if equipped, for power seat)
A driver position memory system is
provided to store and recall the driv-
er seat and outside rearview mirror
position with a simple button opera-
tion. By saving the desired position
into the system memory, different
drivers can reposition the driver seat
and outside rearview mirror based
upon their driving preference. If the
battery is disconnected, the desired
seat position memory will need to be
re-saved.
Storing positions into memoryusing the buttons on the door
Storing driver’s seat positions
1. Shift the shift lever into P while the engine start/stop button is ON.
2. Adjust the driver’s seat and out- side rearview mirror comfortable
for the driver.
3. Press SET button on the control panel. The system will beep once.
4. Press one of the memory buttons (1 or 2) within 5 seconds after
pressing the SET button. The sys-
tem will beep twice when memory
has been successfully stored.
When recalling an adjustment mem-
ory button while sitting in the vehicle,
you can be surprised by the setting
chosen if the memory has been
adjusted by someone else. If that
occurs, immediately push the seat
position control knob in the direction
of the desired position to stop further
undesired movement.
WARNING - Driver

driver position memory system
while the vehicle is moving.

direction that the control switch is
moved.Easy access function (if equipped)
The system will move the driver's
seat automatically as follows:
With smart key system - It will move the driver’s seat rear-ward when the engine start/stop
button is changed to the OFF
position.
- It will move the driver’s seat for- ward when the engine start/stop
button is changed to the ACC or
START position.
You can activate or deactivate this
feature. Refer to "User settings" in
chapter 4.
Headrest (for front seat)
The driver's and front passenger's
seats are equipped with a headrest
for the occupant's safety and comfort.
The headrest not only provides com-
fort for the driver and front passenger,
but also helps protect the head and
neck in the event of a rear collision.
For maximum effectiveness in case
of an accident, the headrest should
be adjusted so the middle of the
headrest is at the same height of the
center of gravity of an occupant's
head. Generally, the center of gravity
of most people's head is similar with
the height of the top of their eyes.
