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 232.) 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 111.
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.
