LOCKING THE DOORS WITH SMART
FUNCTION
The smart entry and start system will
lock the doors without being inserted
into the door keyhole.
When you exit the vehicle carrying the
smart key and push the lock button on the
outside front door handle or back door
with all the doors closed, all the doors will
be locked provided that the electronic
code in the key corresponds to the regis-
tered ID code for the vehicle.
At this time, you will hear one beep and
the turn signal lights flash once. However,
when you push the lock button on the
outside front door handle or back door
with any door not closed securely, a beep
sounds for 10 seconds.
NOTICE
If the key is in the vehicle, do not
perform door locking operation, or
you might lock your keys inside the
vehicle.
INFORMATION
The rear doors are not equipped
with smart function.
When locking the doors, be sure to
push the lock button on the outside
front door handle or back door
slowly and surely. If you push the
button quickly, the doors may not
lock.
When opening or closing a door, do
not touch the lock button on the
outside door handle or back door. If
you push the button, an alarm
sounds 10 seconds.
When a wireless remote control is
used to lock the doors and a smart
key is left in the effective range of
the smart function in the vehicle,
the doors cannot be unlocked using
the smart function. In this case, use
the wireless remote function to un-
lock the doors.
You cannot activate smart unlocking
functions within 3 seconds after the

UNLOCKING THE DOOR(S) WITH
SMART FUNCTION
The smart entry and start system can
be used to unlock the door(s) without
being inserted into the door keyhole.
When you get close to your vehicle (about
1 m (3 ft.) from each outside front door
handle), and are carrying the smart key,
the electronic code emitted from the key
is automatically checked to determine if it
corresponds to the registered ID code for
the vehicle. When you take hold of the
side back of the outside door handle sur-
face, it will unlock. At this time, two
beeps sound and the turn signal lights
flash twice.When you push and hold down the back
door opener switch, carrying the smart
key, the ID code is checked in the same
way as in the front door case. And all the
doors will unlock. At this time, two beeps
sound and the turn signal lights flash
twice.
When you get close to your vehicle (about
1 m or 3 ft. from either front door), carry-
ing the smart key or unlock the back door
using smart key function, the interior light
comes on for 15 seconds if the interior
light switch is in the “DOOR” position.
However, the interior lights go out when
you push the power door lock switch in
the lock position or press the “POWER”
switch once or twice from the off setting
to select the “ACC” or “IG
−ON” mode
without depressing the brake pedal. For
further information, see “Interior lights” on
page 115.
You have 30 seconds to open a door after
operating the smart unlocking function. If
a door is not opened by then, all the
doors will be automatically locked again.
INFORMATION
The rear doors are not equipped
with smart function.
When unlocking the door(s), be sure
to take hold of the back side of the
outside door handle firmly as
shown in the illustration. Taking
hold of the handle with a gloved
hand might cause a delay in unlock-
ing.

32
When you take hold of the handle
or push the back door opener to
unlock the door(s), be sure to con-
firm that the door(s) have been un-
locked. If the two beeps and the
turn signal lights flash twice, the
doors are unlocked. At this time,
you can pull the outside door han-
dle or push the back door opener to
open the door. If you quickly move
closer to the vehicle or pull the out-
side door handle or push the back
door opener quickly, the doors
might not unlock. If you cannot
open the door by pulling the out-
side door handle or pushing the
back door at this time, push back
the outside door handle to the origi-
nal position or release your hand
from the back door and then try
again.
If you bring the smart key very
close to the outside door handle or
the back door opener, the doors
might not lock.
If another person who is not carry-
ing a smart key takes hold of an
outside door handle or push the
back door opener when you are
within the effective range of the
smart function, the door(s) may not
unlock.
If a large amount of water is ap-
plied to the outside door handle or
the back door during heavy rain or
a car wash, and someone carrying a
smart key is near the vehicle, the
door(s) might be unlocked. However,
if the outside front door handle is
not pulled out or back door opener
not pushed, the doors will lock au-
tomatically after about 30 seconds.
To ensure the unlocking door(s),
perform unlocking operation within
3 seconds after getting close to the
vehicle (about 1 m or 3 ft. from the
front doors or back door). If it
takes longer than that, unlocking
function may not be enabled.
CHANGING THE DOORS TO BE UN-
LOCKED
Each time you push the lock button
together with the panic button on the
smart key for about 5 seconds with the
hybrid system off, the setting for door
unlocking will change as follows:
1. Driver ’s door unlocking mode: If you
perform smart unlocking operation on
the driver’s door, it will unlock. Per-
forming unlocking operation on the
front passenger ’s door or back door
will unlock all the doors. When the
system switches to this m ode, one
beep sounds inside the vehicle and two
beeps sound three times.
2. All doors unlocking mode: Performing
smart unlocking operation on either
front door or back door will unlock all
the doors. When the system switches
to this mode, one beep sounds inside
the vehicle and two beeps sound twice.
3. Single door unlocking mode: The
driver ’s door or back door on which
you perform smart unlocking operation
will unlock. However, performing un-
locking operation on the front passen-
ger’s door will unlock all the doors.
When the system switches to this
mode, one beep sounds inside the ve-
hicle and two beeps sound once.

33
INFORMATION
When changing the mode, be sure
to push both lock and panic but-
tons firmly, or panic alarm may be
activated.
 This operation will not change the
wireless remote control unlocking
function.
 In the single or driver’s door un-
locking mode, if you get into the
vehicle from the driver’s door carry-
ing the smart key, all the smart un-
locking controls activated by the
smart key will be stopped for secu-
rity. If you get out of the vehicle
from the driver’s door carrying the
smart key and get out of the effec-
tive range of the smart function,
unlocking control by the smart key
will be possible. However, unlocking
control may not be carried out for
5 seconds after you get out from
the vehicle. In this case, operate
unlock control again after 5 sec-
onds.
BATTERY POWER SAVING
When doors are locked, the smart entry
and start system transmits electromagnetic
waves to the outside of the vehicle at
regular intervals. For this reason, the ve-
hicle battery will be discharged if the ve-
hicle is left for a long time. If the key is
left within the effective range of the smart
function outside of the vehicle, the key
and the vehicle transmit electromagnetic
waves periodically. If these conditions con-
tinue for a long time, the battery in the
key and vehicle will be discharged.
To prevent the batteries from being dis-
charged, the smart function is automatical-
ly deactivated in the following conditions:
If there is no response from the key
for more than 14 days
If the key is left within the effective
range of the smart function outside of
the vehicle for more than 10 minutes To reactivate the smart function, perform
any of the following:
(a) Press the lock button on the outside front door handle or back door while
carrying the smart key.
(b) Perform a wireless remote control op- eration.
(c) Insert and turn the mechanical key in the keyhole of the driver’s door.

34
INFORMATION
To maintain communication with the
vehicle, smart keys use builtin bat-
tery power. The battery service life
is about 1 to 3 years on average. If
battery power becomes insufficient,
replace the battery with a new one.
The smart key continually receives
electromagnetic waves, and if it re-
ceives strong electromagnetic waves
over a period of time, the battery
can be drastically run down. There-
fore, avoid storing smart keys near
any electrical appliances.Here is a list of electrical ap-
pliances which may have adverse
effects on the smart key perfor-
mance: TVs, personal computers,
cellular phone or cordless phone
recharger units, electric light stands
and fluorescent desk lights
Note that you should always keep
such electrical appliances at least 1
m (3 ft.) away from the smart key.
