Maintenance and care
CAUTION
■To prevent damage to the vehicle
■Replacing a tire
●Do not try to remove the ornament by hand. Take due care in handling
the ornament to avoid unexpected personal injury.
●Failure to follow these precautions could cause the wheel nuts to
loosen and the tire to fall off, resulting in death or serious injury.
• Have the wheel nuts tightened with a torque wrench to 76 ft
•lbf (103
N
•m, 10.5 kgf•m) as soon as possible after changing wheels.
• Do not attach a heavily damaged wh eel ornament, as it may fly off
the wheel while the vehicle is moving.
●Do not use a tire jack because its
arms may interfere with the traction
battery in the vehicle underbody.
●Forcibly using a tire jack may damage
the traction battery or cause the vehi-
cle to fall off the jack, resulting in
death or serious injury.

■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure ma y result in the following:
●Reduced traction battery efficiency
●Reduced driving comfort and tire life
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating, have it checked by your Toyota dealer.
■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been
driven for more than 1 mile or 1.5 km, you will get an accurate cold
tire inflation pressure reading.
●Always use a tire pressure gauge.
The appearance of the tire can be mi sleading. In addition, tire infla-
tion pressure that is even just a few pounds off can affect ride quality
and handling.
●Do not reduce tire inflation pressure after driving. It is normal for tire
inflation pressure to be higher after driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle
is balanced.

These parts are small and if swallowed by a child, they can cause choking.
Keep away from children. Failure to do so could result in death or serious
injury.
NOTICE
■For normal operation after re placing the electronic key battery
Observe the following precautions to prevent accidents.
● Always work with dry hands.
Moisture may cause the battery to rust.
● Do not touch or move any other component inside the remote control.
● Do not bend either of the battery terminals.
