Active head restraints
When the occupant’s lower back
presses against the seatback dur-
ing a rear-end collision, the head
restraint moves slightly forward
and upward to help reduce the risk
of whiplash on the seat occupant.
■The auto away function for exiting the driver seat
If the seat is already close to the rearmost position, the auto away function may not
operate when the driver exits the vehicle.
■Active head restraints
Even small forces applied to the seatback may cause the head restraint to move.
Pushing up a locked head restraint forcibly may appear the head restraint inner
structure. These do not indicate problems.
■Customization
The distance that the driver’s seat moves backward during the auto away function
can be changed. (Customizable features →P. 5 8 4 )

CAUTION
■Seat adjustment
To reduce the risk of sliding under the lap belt during a collision, do not recline the
seat more than necessary.
If the seat is too reclined, the lap belt may slide past the hips and apply restraint
forces directly to the abdomen, or your neck may contact the shoulder belt,
increasing the risk of death or serious injury in the event of an accident.
Adjustments should not be made while driving as the seat may unexpectedly move
and cause the driver to lose control of the vehicle.

Driving position memory (driver’s seat)∗∗
: If equipped
Your preferred driving position (the po sition of the driver’s seat, steering
wheel and outside rear view mirrors) can be memorized and recalled with
the touch of a button. It is also possible to set this function to activate auto-
matically when the doors are unlocked.
Three different driving positions can be entered into memory.
■ Entering a position to memory
Check that the shift position is in P.
Turn the “POWER” switch to ON mode.
Adjust the driver’s seat, steering wheel and outside rear view
mirrors to the desired positions.
While pressing and holding the
“SET” button, or within 3 sec-
onds of pressing the “SET” but-
ton, press button 1, 2 or 3 until
the signal beeps.
If the selected button has
already been preset, the previ-
ously recorded position will be
overwritten.
■Recalling the memorized position
Check that the shift position is in P.
Turn the “POWER” switch to ON mode.
Press button 1, 2 or 3 until the
signal beeps to recall the
desired position.

Linking driving position memory with door unlock operation
Record your driving position to button 1, 2 or 3 before performing the fol-
lowing:
Carry only the key (including the card key) to which you want to link the
driving position. If 2 or more keys are in the vehicle, the driving position
cannot be linked properly.
Shift the shift position to P and close the driver’s door. Turn the
“POWER” switch to ON mode. Press the desired button (1, 2 or 3)
to recall the position. Then, while
keep pressing the button, press the
driver’s door lock switches (either
lock or unlock) until the signal
beeps.
The driving position is recalled
when the driver’s door is unlocked
using the entry function or wireless
remote control and the driver ’s
door is opened.

■Operating the driving position memory after turning the “POWER” switch off
Memorized positions (except for the steering wheel position) can be activated up
to 180 seconds after the driver’s door is opened and another 60 seconds after it is
closed again, even after turning the “POWER” switch off.
■Canceling the linked door unlock operation
Turn the “POWER” switch to ON mode and close the driver’s door.
While pressing the “SET” button, press the driver’s door lock switches
(either lock or unlock) until the signal beeps.
■Stopping seat position operation part-way through
Perform any of the following operations:
●Press the “SET” button.
●Press button 1, 2 or 3.
●Adjust the seat using the switches (only cancels seat position recall).
●Adjust the steering wheel using the tilt and telescopic steering control switch
(only cancels steering wheel position recall).
■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 cur-
rent position and the memorized position will not be correctly recalled.
■Customization
If a seat position is memorized, the driver seat will move back the set distance
(→ P. 584) from that memorized position.
CAUTION
■Seat adjustment caution
Take care during seat adjustment so that the seat does not strike the rear passenger
or squeeze your body against the steering wheel.

Seat belts
Make sure that all occupants are wearing their seat belts before driving the
vehicle.
■Correct use of the seat belts
●Extend the shoulder belt so
that it comes fully over the
shoulder, but does not come
into contact with the neck or
slide off the shoulder.
● Position the lap belt as low as
possible over the hips.
● Adjust the position of the
seatback. Sit up straight and
well back in the seat.
● Do not twist the seat belt.
■ Fastening and releasing the seat belt

Seat belt pretensioners (front and outside rear seats)
The pretensioner helps the seat
belt to quickly restrain the occu-
pant by retracting the seat belt
when the vehicle is subjected to
certain types of severe frontal colli-
sion.
The pretensioner may not activate
in the event of a minor frontal
impact, a side impact, a rear impact
or a vehicle rollover.
Pre-collision seat belts (front seats of vehicles with pre-collision system)
If the pre-collision sensor detects that a collision is unavoidable, the pre-
collision system will retract the seat belt, thus enhancing the effectiveness
of the seat belt pretensioner in a crash.
The same will happen if the driver makes an emergency braking or loses con-
trol of the vehicle. ( →P. 2 4 5 )
■Adjusting the seat belt shoulder anchor height (front seats)
Push the seat belt shoulder
anchor down while pressing
the release button.
Push the seat belt shoulder
anchor up.
Move the height adjuster up and
down as needed until you hear a
click.

■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. It may also lock if
you lean forward too quickly. A slow, easy motion will allow the belt to extend so that
you can move around fully.
■Automatic locking retractor (ALR)
When a passenger’s shoulder belt is completely extended and then retracted even
slightly, the belt is locked in that position and cannot be extended. This feature is
used to hold the child restraint system (CRS) firmly. To free the belt again, fully
retract the belt and then pull the belt out once more. ( →P. 1 3 0 )
■Pregnant women
■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. ( →P. 77)
■Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult size.
●Use a child restraint system appropriate for the child, until the child becomes
large enough to properly wear the vehicle’s seat belt. ( →P. 1 2 6 )
●When the child becomes large enough to properly wear the vehicle’s seat belt,
follow the instructions on P. 77 regarding seat belt usage. Obtain medical advice and wear the seat belt
in the proper way. (
→P. 77)
Women who are pregnant should position
the lap belt as low as possible over the hips in
the same manner as other occupants. Extend
the shoulder belt completely over the shoul-
der and position the belt across the chest.
Avoid belt contact over the rounding of the
abdominal area.
If the seat belt is not worn properly, not only
the pregnant woman, but also the fetus could
suffer death or serious injury as a result of
sudden braking or a collision.
