■
Air conditioning on/off
Switch the air conditioning ( ) to off when it is not needed. Doing
so can help control excessive gasoline consumption.
In summer: In high temperatures, use the recirculated air mode. Doing
so will help to reduce the burden on the air conditioner and reduce fuel
consumption as well.
In winter: Because the gasoline engine will not automatically cut out
until the gasoline engine and the interior of the vehicle are warm, it will
consume fuel. Also, fuel consumption can be improved by avoiding
overuse of the heater.
■Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Improper tire
inflation pressure can cause poor fuel consumption.
Also, as snow tires can cause large amounts of friction, their use on dry
roads can lead to poor fuel consumption. Use a tire that is appropriate
for the season.
■Luggage
Carrying heavy luggage can lead to poor fuel consumption. Avoid car-
rying unnecessary luggage. Installing a large roof rack can also cause
poor fuel consumption.
■Warming up before driving
Since the gasoline engine starts up and cuts out automatically when
cold, warming up the engine is unnecessary. Moreover, frequently driv-
ing short distances will cause the engine to repeatedly warm up, which
can lead to poor fuel consumption.

■
Key number plate
Keep the plate in a safe place such as your wallet, not in the vehicle. In the
event that a mechanical key is lost, a new key can be made at your Toyota
dealer using the key number plate. ( P. 476)
■ When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not
press any buttons on the electronic key while inside the aircraft cabin. If you
are carrying an electronic key in your bag etc., ensure that the buttons are
not likely to be pressed accidentally. Pressing a button may cause the elec-
tronic key to emit radio waves that could interfere with the operation of the
aircraft.

NOTICE
■To prevent key damage
Observe the following:
● Do not drop the keys, subject them to strong shocks or bend them.
● Do not expose the keys to high temperatures for long periods of time.
● Do not get the keys wet or wash them in an ultrasonic washer etc.
● Do not attach metallic or magnetic materials to the keys or place the keys
close to such materials.
● Do not disassemble the keys.
● Do not attach a sticker or anything else to the surface of the electronic key.
● Do not place the keys near objects that produce magnetic fields, such as
TVs, audio systems and glass top ranges, or medical electrical equipment,
such as low-frequency therapy equipment.
■ Carrying the electronic key on your person
Carry the electronic key 3.9 in. (10 cm) or more away from electric appli-
ances that are turned on. Radio waves emitted from electric appliances
within 3.9 in. (10 cm) of the electronic key may interfere with the key, causing
the key to not function properly.
■ In case of a smart key system malf unction or other key-related prob-
lems
Take your vehicle with all the electronic keys provided with your vehicle to
your Toyota dealer.
■ When a vehicle key is lost
If the key remains lost, the risk of vehicle theft increases significantly. Visit
your Toyota dealer immediately with all remaining electronic keys that was
provided with your vehicle.
