you do not press any button on the key while inside the aircraf t cabin. If you
are carrying the key in your bag, etc., ensure that the buttons are not likely to
be pressed accidentally. Pressing a button may cause the key to emit radio
waves that could interfere with the operation of the aircraft.
■ Conditions affecting operation (type C or type D)
Type C
The wireless remote control function may not operate normally i n the follow-
ing situations:
● Near a TV tower, radio station, electric power plant, airport o r other facility
that generates strong radio waves
● When carrying a portable radio, cellular phone or other wireles s communi-
cation devices
● When multiple wireless keys are in the vicinity
● When the wireless key is in contact with, or is covered by a me tallic object
● When a wireless key (that emits radio waves) is being used near by

Type D
● The standard battery life is 1 to 2 years.
● If the battery becomes low, an alarm will sound in the cabin wh en the engine
stops. ( P. 502)
● As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indi-
cate that the electronic key battery may be depleted. Replace the battery
when necessary. ( P. 445)
• The smart key system or the wireless remote control does not o perate.

ment, such as low-frequency therapy equipment.
■ Carrying the electronic key on your person (type D)
Carry the electronic key 10 cm (3.9 in.) or more away from electric appli-
ances that are turned on. Radio waves emitted from electric app liances
within 10 cm (3.9 in.) of the electronic key may interfere with the key, caus-
ing the key to not function properly.
■ In case of a smart entry & start system malfunction or other key-related
problems (type D)

■Caution regarding interfer ence with electronic devices
● People with implantable cardiac pacemakers, cardiac resynchroni zation
therapy-pacemakers or implantable cardioverter defibrillators s hould 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 entr y function.
● User of any electrical medical device other than implantable ca rdiac pace-
makers, cardiac resynchronization therapy-pacemakers or implant able
cardioverter defibrillators should consult the manufacturer of the device for

WARNING
■If you hear a squealing or scrap ing noise (brake pad wear limit indica-
tors)
Have the brake pads checked and replaced by your Toyota dealer as soon
as possible.
Rotor damage may result if the pads are not replaced when neede d.
It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or those of the brake discs are exceeded.
■ When the vehicle is stopped
● Do not race the engine.
If the vehicle is in any gear other than P (automatic transmiss ion only) or
N, the vehicle may move suddenly and unexpectedly, causing an a ccident.
● On vehicles with an automatic transmission, in order to prevent accidents
due to the vehicle rolling away, always keep depressing the bra ke pedal
while the engine is running, and apply the parking brake as nec essary.
● If the vehicle is stopped on an incline, in order to prevent ac cidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
● Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped m ay cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.
■ When the vehicle is parked
● Do not leave glasses, cigarette lighters, spray cans, or soft d rink cans in
the vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may le ad to a
fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic material of glasses to deform or crack.
• Soft drink cans may rupture, causing the contents to spray ove r the
interior of the vehicle, and may also cause a short circuit in the vehicle’s
electrical components.
● Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a
place such as the glove box or on the floor, it may be lit acci dentally when
luggage is loaded or the seat is adjusted, causing a fire.
● Do not attach adhesive discs to the windshield or windows. Do n ot place
containers such as air fresheners on the instrument panel or da shboard.
Adhesive discs or containers may act as lenses, causing a fire in the vehi-
cle.
