Before Driving
●The driver must carry the key to ensure the system functions properly.
● Always keep a spare key in case one is lost. If a key is lost, consult your
Toyota dealer as soon as possible.
WARNING
■Do not leave the key in your vehicl e with children and keep them in a
place where your children will not find or play with them
Leaving children in a vehicle with the key is dangerous. This could result in
someone being badly injured or even killed. Children may find these keys to
be an interesting toy to play with and could cause the power windows or
other controls to operate, or even make the vehicle move.
NOTICE
● Because the key (smart key) uses low-intensity radio waves, it may not
function correctly under the following conditions:
• The key is carried with communication devices such as cellular phones.
• The key contacts or is covered by a metal object.
• The key is near electronic devices such as personal computers.
• Non-Toyota genuine electronic equipment is installed in the vehicle.
• There is equipment which discharges radio waves near the vehicle.
● The key (smart key) may consume battery power excessively if it receives
high-intensity radio waves. Do not place the key near electronic devices
such as televisions or personal computers.
● To avoid damage to the key (smart key), DO NOT:
• Drop the key.
• Get the key wet.
• Disassemble the key.
• Expose the key to high temperatures on places such as the dashboard
or hood, under direct sunlight.
• Expose the key to any kind of magnetic field.
• Place heavy objects on the key.
• Put the key in an ultrasonic cleaner.

Before Driving
●The keyless entry system operation may vary due to local conditions.
● The keyless entry system is fully operational (door/trunk lid lock/unlock)
when the ignition is switched off. The system does not operate if the ignition
is switched to any position other than off.
● If the key does not operate when pressing a button or the operational range
becomes too small, the battery may be dead. To install a new battery, refer
to Key Battery Replacement ( →P. 436).
● Additional keys can be obtained at your Toyota dealer. Up to 6 keys can be
used with the keyless functions per vehicle. Bring all keys to your Toyota
dealer when additional keys are required.

The operation indicator light
flashes when the buttons are
pressed.
● Battery life is about one year. Replace
the battery with a new one if the KEY
indicator light (green) flashes in the com-
bination meter. Replacing the battery

ing on the rate of battery depletion.

2-2. Door and Locks
Door Locks
When the ignition is switched to ACC or ON, the vehicle lock-out pre-
vention feature prevents you from locking yourself out of the vehicle.
All doors and the trunk lid will autom atically unlock if they are locked
using the power door locks with any door open.
The vehicle lock-out prevention feature does not operate while the
ignition is switched off.
When any door is opened from the outside while the key is inside the
vehicle, the closed doors are locked. All the doors are automatically
unlocked by closing the open door.
The horn sound is heard twice to notify the driver that the key has
been left in the vehicle.
■ Door unlock (control) system with collision detection
This system automatically unlocks the doors in the event the vehicle is
involved in an accident to allow passengers to get out of the vehicle immedi-
ately and prevent being trapped inside. While the ignition is switched ON and
in the event the vehicle receives an impact strong enough to inflate the air
bags, all the doors are automatically unlocked after about 6 seconds have
elapsed from the time of the accident.
The doors may not unlock depending on how an impact is applied, the force
of the impact, and other conditions of the accident.
If door-related systems or the battery is malfunctioning, the doors will not
unlock.
