■If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, engine coolant reservoir cap, drain cock
and water pump.
If you cannot find a leak, have any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional, test the cap and check for
leaks in the cooling system.
■ Coolant selection
XGasoline engine
Only use “Toyota Super Long Life Coolant” or similar high quality ethylene
glycol based non-silicate, non-amine, non- nitrite, and non-borate coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-
ized water. (Enabled: -35 °C [-31 °F])
XDiesel engine
Only use “Toyota Genuine Premium Long Life Coolant 1WW/2WW” or equiv-
alent. “Toyota Genuine Premium Long Life Coolant 1WW/2WW” concen-
trated product always needs to be mixed as 50% coolant and 50% deionized
water. (Enabled: -35 °C [-31 °F])
For more details about engine coolant, contact any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
WARNING
■ When the engine is hot
Do not remove the coolant reservoir cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
NOTICE
■When adding engine coolant
Coolant is neither plain water nor stra ight antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion
protection and cooling. Be sure to read the antifreeze or coolant label.
■ If you spill coolant
Be sure to wash it off with water to prevent damage to parts or paint.

■How to initialize the tire pressure warning systemPark the vehicle in a safe place and turn the engine switch to the
“LOCK” position (vehicles without smart entry & start system) or
off (vehicles with smart entry & start system).
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( →P. 613)
Make sure to adjust the tire pressure to the specified cold tire inflation
pressure level. The tire pressure warning system will operate based on
this pressure level.
Turn the engine switch to the “ON” position (vehicles without
smart entry & start system) or IGNITION ON mode (vehicles with
smart entry & start system).
XVehicles with monochrome display
Press the “DISP” switch until the settings screen appears.
(→ P. 108)
Press and hold the “DISP” switch to enter the adjustment mode.
Press the “DISP” switch until the menu of tire pressure warning
system appears.

Situations in which the tire pressure warning system may not operate
properly (if equipped)
●In the following cases, the tire pressure warning system may not operate
properly.
• If non-genuine Toyota wheels are used.
• A tire has been replaced with a tire t hat is not an OE (Original Equipment)
tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• An auxiliary-supported run-flat tire is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the
wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.
• If tires not equipped with the tire pr essure warning valves and transmit-
ters are used.
• If the ID code on the tire pressure warning valves and transmitters is not
registered in the tire pressure warning computer.
• If the wheel set selected does not match the wheel set fitted to the vehi- cle, in case a second wheel set has been registered.
● Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electri-
cal noise
• When carrying a portable radio, cellular phone, cordless phone or other wireless communication device
● When the vehicle is parked, the time taken for the warning to start or go off
could be extended.
● When tire inflation pressure declines rapidly for example when a tire has
burst, the warning may not function.
■ The initialization operation (vehicles with the tire pressure warning sys-
tem)
●Make sure to carry out initialization after adjusting the tire inflation pressure.
Also, make sure the tires are cold before carrying out initialization or tire
inflation pressure adjustment.
● If you have accidentally turned the engine switch to the “LOCK” position
(vehicles without a smart entry & start system) or off (vehicles with a smart
entry & start system) during initialization, it is not necessary to restart the ini-
tialization again as initialization will restart automatically when the engine
switch has been turned to the “ON” position (vehicles without a smart entry
& start system) or IGNITION ON mode (vehicles with a smart entry & start
system) for the next time.
● If you accidentally start the initialization when initialization is not necessary,
adjust the tire inflation pressure to the specified level when the tires are
cold, and conduct initialization again.
