Operation of each component
■Note for the entry function
●Even when the electronic key is within the effective range (detection areas),
the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near
the ground, or in a high place when the doors are locked or unl ocked.
• The electronic key is on the instrument panel or floor, or in the console
box or glove box when the engine is started or engine switch mo des are
changed.
● Do not leave the electronic key on top of the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio w ave recep-
tion conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the outside, possibly trapping the electronic
key inside the vehicle.
● As long as the electronic key is within the effective range, th e doors may be
locked or unlocked by anyone. However, only the doors detecting the elec-
tronic key can be used to unlock the vehicle.
● Even if the electronic key is not inside the vehicle, it may be possible to start
the engine if the electronic key is near the window.
● The doors may unlock or lock if a large amount of water splashes on the
door handle, such as in the rain or in a car wash, when the electronic key is
within the effective range. (The doors will automatically be lo cked after
approximately 60 seconds if the doors are not opened and closed.)
● If the wireless remote control is used to lock the doors when t he electronic
key is near the vehicle, there is a possibility that the door m ay not be
unlocked by the entry function. (Use the wireless remote contro l to unlock
the doors.)
● Touching the door lock or unlock sensor while wearing gloves ma y prevent
lock or unlock operation. Remove the gloves and touch the lock sensor
again.
● When the lock operation is performed using the lock sensor, rec ognition sig-
nals will be shown up to two consecutive times. After this, no recognition
signals will be given.
● If the door handle becomes wet while the electronic key is with in the effec-
tive range, the door may lock and unlock repeatedly. In this case, follow the
following correction procedures to wash the vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more awa y from the
vehicle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the s mart key
system. ( P. 133)
● If the electronic key is inside the vehicle and a door handle b ecomes wet
during a car wash, a message may be shown on the multi-informat ion dis-
play and a buzzer will sound outside the vehicle. To turn off t he alarm, lock
all the doors.

WARNING
■Caution regarding interfer ence with electronic devices
● People with implantable cardiac pacemakers, cardiac resynchroni zation
therapy-pacemakers or implantable cardioverter defibrillators should keep
away from the smart key system antennas. ( P. 131)
The radio waves may affect the operation of such devices. If ne cessary,
the entry function can be disabled. Ask your Toyota dealer for details, such
as the frequency of radio waves and timing of the emitted radio waves.
Then, consult your doctor to see if you should disable the entry function.
● User of any electrical medical device other than implantable cardiac pace-
makers, cardiac resynchronization therapy-pacemakers or implantable
cardioverter defibrillators should consult the manufacturer of the device for
information about its operation under the influence of radio waves.
Radio waves could have unexpected effects on the operation of such
medical devices.
Ask your Toyota dealer for details for disabling the entry function.

WARNING
■Cautions regarding the use of the system
There is a limit to the degree of recognition accuracy and cont rol perfor-
mance that this system can provide, do not overly rely on this system. The
driver is always responsible for paying attention to the vehicl e’ surroundings

Failing to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.
● Do not damage the sensors, and always keep them clean.
● Do not attach a sticker or install an electronic component, such as a backlit
license plate (especially fluorescent type), fog lights, fender pole or wire-
less antenna near a radar sensor.
● Do not subject the surrounding area of the sensor to a strong impact. If
subjected to an impact, have the vehicle inspected by your Toyota dealer.
If the front or rear bumper needs to be removed/installed or replaced, con-
tact your Toyota dealer.
● Do not modify, disassemble or paint the sensors.
● Do not attach a license plate cover.

■ Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor a rea.
Doing so may result in the sensor malfunctioning.
● When using a high pressure washer to wash the vehicle, do not spray the
sensors directly, as doing so may cause a sensor to malfunction .
● When using steam to clean the vehicle, do not direct steam too close to
the sensors as doing so may cause a sensor to malfunction.

4026-1. Maintenance and care
Cleaning and protecting the vehicle exterior
●Working from top to bottom, liberally apply water to the vehicl e
body, wheel wells and underside of the vehicle to remove any di rt
and dust.
● Wash the vehicle body using a sponge or soft cloth, such as a
chamois.
● For hard-to-remove marks, use car wash soap and rinse thoroughl y
with water.
● Wipe away any water.
● Wax the vehicle when the wate rproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.
■Automatic car washes
●Fold the mirrors before washing the vehicle. Start washing from the front of
the vehicle. Make sure to extend the mirrors before driving.
● Brushes used in automatic car washes may scratch the vehicle su rface,
parts (wheel, etc.) and harm your vehicle’s paint.
● In certain automatic car washes, the roof antenna may interfere with
machine operation. This may prevent the vehicle from being clea ned prop-
erly or result in damage to the antenna.
■ High pressure car washes
As water may enter the cabin, do not bring the nozzle tip near the gaps
around the doors or perimeter of the windows, or spray these ar eas continu-
ously.
Perform the following to protect the vehicle and maintain it in
prime condition:
