872-1. Keys
2
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.
• Put any magnetized objects close to the key.

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
about once a year is recommended
because the KEY warning light/indicator
light may not illuminate or flash depend-
ing on the rate of battery depletion.
NOTICE

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.

2-7. Security System
Theft Deterrent System∗
The system will not function unless it’s properly armed. So when you
leave the vehicle, follow the arming procedure correctly.
■System triggering conditions
The horn sounds intermittently and the hazard warning lights flash
for about 30 seconds when the sy stem is triggered by any one of
the following: • Unlocking a door with the key, door lock switch, or an inside door-lock knob.
• Forcing open a door, the hood or the trunk lid.
• Opening the hood by operating the hood release handle.
• Switching the ignition ON without using the push button start.
If the system is triggered again, th e lights and horn will activate until
the driver’s door or the trunk lid is unlocked with the smart key.
● The trunk lid does not open while the theft deterrent system is operating.
● If the battery goes dead while the theft deterrent system is armed, the horn
will activate and the hazard warning lights will flash when the battery is
charged or replaced.
∗: If equipped
If the theft deterrent system detects an inappropriate entry into
the vehicle, which could result in the vehicle or its contents
being stolen, the alarm alerts th e surrounding area of an abnor-
mality by sounding the horn and flashing the hazard warning
lights.

When Driving
■Push Button Start Positions
●The engine starts by pressing the push button start while depressing the
clutch pedal (manual transaxle) or the brake pedal (automatic transaxle). To
switch the ignition position, press the push button start without depressing
the pedal.
● Do not leave the ignition switched ON while the engine is not running. Doing
so could result in the battery going dead. If the ignition is left in ACC (For
automatic transaxle, the selector lever is in the P position, and the ignition is
in ACC), the ignition switches off automatically after about 25 minutes.
■ ACC (Accessory)
The keyless entry system does not function while the push button start has
been pressed to ACC, and the doors will not lock/unlock even if they have
been locked manually.
■ ON
When the push button start is pressed to ON, the sound of the fuel pump
motor operating near the fuel tank can be heard. This does not indicate an
abnormality.
WARNING
■Before leaving the driver’s seat, set the parking brake, make sure the
selector lever is in 1st gear or R (manual transaxle) or in P (automatic
transaxle), and always switch the ignition off
Leaving the driver’s seat without setting the parking brake, shifting the
selector lever to 1st gear or R (manual transaxle) or to P (automatic tran-
saxle), and switching the ignition off is dangerous. Unexpected vehicle
movement could occur which could result in an accident.
In addition, if your intention is to l eave the vehicle for even a short period, it
is important to switch the ignition off, as leaving it in another position will dis-
able some of the vehicle’s security systems and run the battery down.

When Driving
After starting the engine, let it idle for about ten seconds.
●The key must be carried because the key carries an immobilizer chip that
must communicate with the engine controls at short range.
● The engine can be started when the push button start is pressed from off,
ACC, or ON.
● The push button start system functions (function which can start the engine
by only carrying the key) can be deactivated to prevent any possible
adverse effect on a user wearing a pacemaker or other medical device. If
the system is deactivated, you will be unable to start the engine by carrying
the key. Consult your Toyota dealer for details. If the push button start sys-
tem functions have been deactivated, you can start the engine by following
the procedure indicated when the key battery goes dead.
Refer to Engine Start Function When Key Battery is Dead on P. 145.
● After starting a cold engine, the engine speed increases and a whining
sound from the engine compartment can be heard.
This is for improved exhaust gas purification and does not indicate defect of
the parts.
● Engine-starting is controlled by the spark ignition system.
This system meets all Canadian Interference-Causing Equipment Standard
requirements regulating the impulse electrical field strength of radio noise.
● Under the following conditions, the KEY warning light (red) flashes after the
push button start is pressed to inform the driver that the push button start
will not switch to ACC even if it is pressed from off.
• The key battery is dead.
• The key is out of operational range.
• The key is placed in areas where it is difficult for the system to detect the
signal ( →P. 93).
• A key from another manufacturer similar to the key is in the operational
range.
