Locking the doors with smart key system
11L224
The smart key 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 door handle with all the doors
closed, all the doors will be locked provided that the electronic
code in the key corresponds to the registered 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 door handle with any door not closed securely, a beep
sounds for 10 seconds. (For details, see page 27.)
If outer foot lights are illuminated, you can turn off the lights by
pushing the “LOCK” button on the smart key. (For details, see
“Outer foot lights” on page 233.)
INFORMATION
 When locking the doors, be sure to push the lock
button on the outside door handle 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.
 When a wireless key is used to lock the doors and a
smart key is left in the ef fective range of the smart key
system in the vehicle, the doors cannot be unlocked
using the smart key system. In this case, use the
wireless remote function to unlock the doors.
 You cannot activate smart unlocking functions

with a smart key left in the vehicle, an alarm sounds for 2
seconds and the doors will not lock.
Before you push the lock button, make sure you are carrying
the smart key.
INFORMATION
 Do not put a smart key on the instrument panel, rear
package tray or floor, or in the glove box or auxiliary
box near the selector lever, which falls outside of the
effective range of the smart key system. As the alarm
does not sound when a key is left in such a place, you
might accidentally lock the doors by pushing the lock
button on the outside door handle and be locked out
of the vehicle. Be sure to take the smart key with you.
 If you have the smart key but bring it very close to the
window or outside door handle, the alarm might
activate. In this case, keep the smart key a certain
distance away from the window or outside door
handle and then push the lock button again.
 If the smart key is left in the vehicle, attempting to
lock the door by pushing in the button located in the
inside door handle and holding up the outside door
handle will unlock all the doors and activate the alarm

KEYS AND DOORS

Unlocking the door(s) with smart key system
11L225
The smart key 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 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. After this, the outer foot lights come on. (For outer foot
lights, see “Outer foot lights” on page 233.) When you take
hold of the back side of the outside door handle on the door
firmly, it will unlock and the key indicator light blinks. (You can
select the doors to be unlocked. For details, see “Changing the
doors to be unlocked” on page 30.) At this time, two beeps sound and the turn signal lights flash
twice. As the door(s) is(are) unlocked, 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 turn the ignition
switch to the “ACC” or “ON” position. For further information,
see “Interior lights” on page 112.
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
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 unlocking
or may not unlock.
 When you take hold of the handle to unlock the
door(s), be sure to confirm that the door(s) has(have)
been unlocked. If the emergency flashers flash twice,
two beeps sound outside the vehicle and the key
indicator starts blinking, the doors are unlocked. At
this time, you can pull the outside door handle to
open the door. If you quickly move closer to the
vehicle or pull the outside door handle quickly, the
doors might not unlock. If you cannot open the door
by pulling the outside door handle at this time, push
it back to the original position and then pull it out
again.
 If you bring the smart key very close to the outside
door handle, the doors might not unlock.
 If another person who is not carrying a smart key
takes hold of an outside door handle when you are
within the effective range of the smart key system, the
door(s) may not unlock.
 If a large amount of water is applied to the outside
door handle during heavy rain or a car wash, and
someone ca rrying a smart key is near the vehicle, the
door(s) might be unlocked. However, if the outside
door handle is not pulled out, the doors will lock
automatically after about 30 seconds.
