Maintenance and care
Engine coolant
The coolant level is satisfactory if it is betw een the “F” and “L” lines on
the reservoir when the engine is cold.
Reservoir cap
FULL
LOW
If the level is on or below the “L”
line, add coolant up to the “F” line.
(→P. 421)
■ If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, engine coolant filler cap, radiator cap,
drain cock and water pump.
If you cannot find a leak, have your Toyota dealer test the cap and check for
leaks in the cooling system.
■ Coolant selection
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.
U.S.A.: “Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deionized water. (Enabled: -31 °F [-35 °C])
Canada: “Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized water. (Enabled: -44 °F [-42 °C])
For more details about engine coolant, contact your Toyota dealer.
CAUTION
■ 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 burns or other injuries.

Radiator and condenserCheck the radiator and condenser and remove any foreign objects.
If any of the above parts are extremely dirty or you are not sure of
their condition, have your vehicle checked by your Toyota dealer.
NOTICE
■When adding engine coolant
Coolant is neither plain water nor straight 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.
CAUTION
■When the engine is hot
Do not touch the radiator or condenser, as they may be hot and may cause
burns.

Power steering fluid■ Fluid level
The fluid level should be within the appropriate range.
Full (when cold)
Add fluid (when cold)
Full (when hot)
Add fluid (when hot)
Hot: Vehicle has been driven around 50 mph (80 km/h) for 20 minutes, or slightly longer in cold temperatures. (Fluid tem-
perature, 140 °F - 175°F [60°C - 80 °C])
Cold: Engine has not been run for about 5 hours. (Room tempera- ture, 50 °F - 85°F [10°C - 30°C])
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.

Maintenance and care
Type B
Green: Good condition
Dark: Charging is necessary.
Have the vehicle inspected by
your Toyota dealer.
Clear or light yellow: Not
working properly, have the
battery checked by your
Toyota dealer.
■Before recharging
When recharging, the battery produces hydrogen gas which is flammable
and explosive. Therefore, before recharging:
●If recharging with the battery installed on the vehicle, be sure to discon-
nect the ground cable.
● Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the battery.
■ After recharging the battery (vehicles with smart key system)
The engine may not start. Follow the procedure below to initialize the sys-
tem.
Shift the shift lever to P.
Open and close any of the doors.
Restart the engine.

Maintenance and care
Washer fluid
Add washer fluid in the following
situations.
●Any washer does not work.
● The low washer fluid warning
light comes on. (if equipped)
● The warning message
appears on the multi-informa-
tion display. (if equipped)
NOTICE
■When recharging the battery
Never recharge the battery while the engine is running. Also, be sure all
accessories are turned off.
CAUTION
■When refilling the washer fluid
Do not refill the washer fluid when the engine is hot or running, as the
washer fluid contains alcohol and may catch fire if spilled on the engine etc.
NOTICE
■Do not use any fluid other than washer fluid
Do not use soapy water or engine antifreeze instead of washer fluid.
Doing so may cause streaking on the vehicle’s painted surfaces.
■ Diluting washer fluid
Dilute washer fluid with water as necessary.
Refer to the freezing temperatures listed on the washer fluid tank.

Installing tire pressure warning valves and transmittersWhen replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new tire pressure warning valve and transmitter ID codes
must be registered in the tire pressure warning computer and the tire
pressure warning system must be initialized. Have tire pressure
warning valve and transmitter ID codes registered by your Toyota
dealer. ( →P. 337)
Initializing the tire pressure warning system
■ The tire pressure warning system must be initialized when
inflation the tire pressure is changed (such as when changing
traveling speed or load weight.)
When the tire pressure warning syst em is initialized, the current tire
inflation pressure is set as the pressure benchmark.
■ How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the “ENGINE START
STOP” switch or the engine switch OFF.
While the vehicle is moving, in itialization is not performed.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. ( →P. 436)
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 START STOP” switch to IGNITION ON
mode (vehicles with smart key system) or engine switch to
“ON” position (vehicles without smart key system).

Registering ID codes The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to regi ster the ID code of tire pressure
warning valve and transmitter. Have the ID code registered by your
Toyota dealer.
