■Battery-saving function
The battery-saving fu nction will be acti-
vated in order to prevent the electronic key
battery and the vehicle battery from being
discharged while the vehicle is not in opera-
tion for a long time.
●In the following situations, the smart
access system with pu sh-button start may
take some time to unlock the doors.
• The electronic key has been left within approximately 6 ft. (2 m) of the outside of
the vehicle for 10 minutes or longer.
• The smart access system with push-but- ton start has not been used for 5 days or
longer.
●If the smart access system with push-but-
ton start has not been used for 14 days or
longer, the doors cann ot be unlocked at
the passenger door. In this case, take hold
of the driver’s door handle, or use the
wireless remote control or mechanical

■Electronic Key Battery-Saving Function
When battery-saving mode is set, battery
depletion is minimized by stopping the elec-
tronic key from receiving radio waves.
Press twice while pressing and holding
. Confirm that the electronic key indica-

While the battery-saving mode is set, the
smart access system with push-button start
cannot be used. To cancel the function,
press any of the electronic key buttons.
■Conditions affecting operation
The smart access system with push-button
start uses weak radio waves. In the following
situations, the communication between the
electronic key and the vehicle may be
affected, preventing the smart access sys-
tem with push-button start, wireless remote
control and engine immobilizer system
from operating properly.

■Note for the entry function
●Even when the electronic key is within the
effective range (detection areas), the sys-
tem may not operate properly in the fol-
lowing cases:
• The electronic key is too close to the win- dow or outside door handle, near the
ground, or in a high place when the doors
are locked or unlocked.
• The electronic key is near the ground or in a high place, or too close to the rear
bumper center when the trunk is opened.
• The electronic key is on the instrument panel, rear package tray or floor, or in the
door pockets or glove box when the
engine is started or engine switch modes
are changed.
●Do not leave the electronic key on top of
the instrument panel or near the door
pockets when exiting the vehicle.
Depending on the radio wave reception
conditions, it may be detected by the
antenna outside the cabin and the doors
will become lockable from the outside,
possibly trapping the electronic key
inside the vehicle.
●As long as the electron ic key is within the effective range, the doors may be locked
or unlocked by anyone. However, only
the doors detecting the electronic key
can be used to unlock the vehicle.
●Even if the electronic
key is not inside the
vehicle, it may be po ssible to start the
engine if the electronic key is near the
window.
●The doors may unlock or lock if a large
amount of water splashes on the door
handle, such as in the rain or in a car
wash, when the electronic key is within
the effective range. (The doors will auto-
matically be locked after approximately
60 seconds if the doors are not opened
and closed.)
●If the wireless remote control is used to
lock the doors when the electronic key is
near the vehicle, there is a possibility that
the door may not be unlocked by the
entry function. (Use the wireless remote
control to unlock the doors.)
●Touching the door lock or unlock sensor
while wearing gloves may prevent lock or
unlock operation.
●When the lock operation is performed
using the lock sensor, recognition signals
will be shown up to two consecutive
times. After this, no recognition signals
will be given.
●If the door handle becomes wet while the
electronic key is within the effective
range, the door may lock and unlock
repeatedly. In this case, follow the follow-
ing correction procedures to wash the
vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more away from the vehicle.
(Take care to ensure that the key is not
stolen.)
• Set the electronic key to battery-saving mode to disable the smart access system
with push-button start. ( P.94)
●If the electronic key is inside the vehicle
and a door handle becomes wet during a
car wash, a message may be shown on
the multi-information display and a
buzzer will sound outside the vehicle. To
turn off the alarm, lock both side doors.
●The lock sensor may not work properly if
it comes into contact with ice, snow, mud,

■When adjusting the seat
●Take care when adjusting the seat so that
the head restraint does not touch the ceil-
ing.
●When folding down a rear seatback, if it
interferes with a front seatback, adjust the
front seat position so that the seats no
longer interfere with each other. How-
ever, if adjusting the front seat position
causes the correct driving posture to not
be maintained, return the rear seatback
to its original position. ( P.99)
Front seats
WARNING
■When adjusting the seat position
●Take care when ad justing the seat
position to ensure that other passen-
gers are not injured by the moving
seat.
●Do not put your hands under the seat
or near the moving parts to avoid
injury.
Fingers or hands may become jammed in
the seat mechanism.
●Make sure to leave enough space
around the feet so they do not get
stuck.
■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.

that has been registered to the driv-
ing position, and then unlock and
open the driver’s door using the
smart access system with push-but-
ton start or wireless remote control.
The driving position will move to the
recorded position (not including the steer-
ing wheel). However, the seat will move to
a position slightly behind the recorded
position in order to make entering the vehi-
cle easier.
If the driving position is in a position that
has already been recorded, the seat and
outside rear view mirrors will not move.
2Turn the engine switch to ACCES-
SORY mode or IGNITION ON
mode, or fasten a seat belt.
The seat and steering wheel will move to
the recorded position.
■Recalling the driving position using the
memory recall function
●Different driving positions can be regis-
tered 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 access system
with push-button start, the driving posi-
tion cannot be recalled. In this case, press

■Defogging the mirrors
The outside rear view mirrors can be
cleared using the mirror defoggers. Turn on
the rear window defogger to turn on the
outside rear view mirror defoggers.
(  P.211)
■Auto anti-glare function (if equipped)
When the anti-glare insi de rear view mirror
is set to automatic mode, the outside rear
view mirrors will activate in conjunction with
the anti-glare inside rear view mirror to
reduce reflected light. ( P.107)
■Automatic adjustment of the mirror
angle (if equipped)
A desired mirror face angle can be entered
to memory and recalled automatically by
the driving position memory. ( P.100)
■Linked mirror function when reversing
(if equipped)
When either “L” or “R” of the mirror select
switch is selected, the outside rear view mir-
rors will automatically angle downwards
when the vehicle is reversing in order to
give a better view of the ground. To disable this function, select neither “L”
nor “R”.
To set the mirror angle used when the vehi-
cle is reversing, adjust the mirror angle at a
desired position with the shift lever in R.
The adjusted angle will be memorized and
the mirror will automatically tilt to the mem-
orized angle whenever the shift lever is
shifted to R from next time.
The memorized downward tilt position of
the mirror is linked to the normal position
(angle adjusted with th
e shift lever in other
than R). Therefore, if the normal position is
changed after adjustment, the tilt position
will also change.
When the normal position is changed, read-
just the angle in reversing.
Push the mirror back in the direction of
the vehicle’s rear.
