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
smart locking function is activated.

31
INFORMATION
When changing the mode, be sure
to push both “ ” (lock) and “ ”
(panic) buttons 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.

The wireless remote control system is
designed to lock or unlock all the side
doors and back door, or activate the
theft deterrent system from a distance
within approximately 1 m (3 ft.) of the
vehicle.

or run down, the back door will be auto-
matically locked and the back door system
