■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 retailer or Toyota autho-
rized repairer, or any reliable repairer, test the cap and check for leaks in the
cooling system.
■ Coolant selection
Gasoline engine
Only use “Toyota Super Long Life Cool ant” 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])
Diesel 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 retailer
or Toyota authorized repairer, or any reliable repairer.
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 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.

●Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the battery.
■After recharging the battery (vehicles with smart entry & start system)
The engine may not start. Follow the procedure below to initialize the system.
Shift the shift lever to P (Multidrive) or depress the brake pedal with the shift
lever in N (manual transmission).
Open and close any of the doors.

If the fluid level is extremely low,
add washer fluid.
Raise the cap keeping your finger
pressed down on the hole in the
center and check the fluid level in
the tube.
NOTICE
■ When recharging the battery
Never recharge the battery while the engine is running. Also, be sure all
accessories are turned off.
Washer fluid
WARNING
■ 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, as well as
damaging the pump leading to problems of the washer fluid not spraying.
■ Diluting washer fluid
Dilute washer fluid with water as necessary.
Refer to the freezing temperatures list ed on the label of the washer fluid bot-

Tires
Check if the treadwear indicators are showing on the tires. Also check
the tires for uneven wear, such as excessive wear on one side of the
tread.
Check the spare tire condition and inflation pressure if not rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators is shown by a “TWI” or “ ” marks,
etc., molded into the sidewall of each tire.
Replace the tires if the treadwear indicators are showing on a tire.

Maintenance and care
With full-size spare tire (vehicles without tire pressure warning sys-
tem)
Rotate the tires in the order
shown.
To equalize tire wear and help
extend tire life, Toyota recom-
mends that you rotate your tires
approximately every 10000 km
(6000 miles).
With full-size spare tire (vehicles with tire pressure warning sys-
tem), compact spare tire, or emergency tire puncture repair kit
Rotate the tires in the order
shown.
To equalize tire wear and help
extend tire life, Toyota recom-
mends that you rotate your tires
approximately every 10000 km
(6000 miles).
Vehicles with a tire pressure warn-
ing system: Do not fail to initialize a
tire pressure warning system after
tire rotation.

Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tire infla-
tion pressure before serious problems arise.
If the tire pressure drops below a predetermined level, the driver is
warned by a warning light. (P. 533)
◆Installing tire pressure warning valves and transmitters
When 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 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 any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer. (P. 472)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the fol-
lowing circumstances:
●When rotating front and rear tires which have different tire infla-
tion pressures
●When changing the tire size
●When the tire inflation pressure is changed such as when chang-
ing traveling speed
●When changing between two registered wheel sets
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.
