Maintenance and care
Engine coolant
The coolant level is satisfactory if it is between the FULL and LOW
lines on the reservoir when the engine is cold.
Reservoir cap
FULL
LOW
If the level is on or below the
LOW line, add coolant up to the
FULL line.
■If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, reservoir cap, radiator cap, drain cock
and water pump.
If you cannot find a leak, have your Toyota dealer pressure 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. (Minimum temperature: -31 F [-35 C])
Canada: “Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized water. (Minimum temperature: -44 F [-42 C])
For more details about engine coolant, contact your Toyota dealer.
CAUTION
■ When the engine is hot
Do not remove the radiator cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing burns or other injuries.

their condition, have your vehicl e checked by your Toyota dealer.
Brake fluid
■ Checking fluid level
The brake fluid level should be
between the MAX and MIN lines
on the reservoir.
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.
CAUTION
■When the engine is hot
Do not touch the radiator or condenser as they may be hot and may cause
burns.

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 frigid temperatures. (Fluid
temperature, 140°F - 175°F [60°C - 80°C])
Cold: Engine has not been run for about 5 hours. (Room tem- perature, 50°F - 85°F[10°C - 30°C])
■ Checking the fluid level
Make sure to check the fluid type and prepare the necessary items.
Clean all dirt off the reservoir.
Remove the cap by turn ing it counterclockwise.
Wipe the dipstick clean.
Reinstall and remove the reservoir cap again.
Check the fluid level.

Maintenance and care
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 tire pressure warning valve and transmitter ID codes must be regis-
tered in the tire pressure warning computer and tire pressure warning
system must be initialized. Have tire pressure warning valve and trans-
mitter ID codes registered by your Toyota dealer. ( P. 456)
Initializing the tire pressure warning system
■ The tire pressure warning system must be initialized in the fol-
lowing circumstances:
●When rotating the tires on vehicles differing with front and rear
tire inflation pressures.
● When changing the tire size.
When the tire pressure warning system 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 safe place and turn 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. 553)
Make sure to adjust the tire pressure to the specified cold tire
inflation pressure level. The ti re pressure warning system will
operate based on this pressure
level.
Turn the engine switch to the ON position.

456 4-3. Do-it-yourself maintenance
Push and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks
slowly three times.
Wait for several minutes with the engine switch on, and then
turn the engine switch to the ACC or LOCK position.
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.
■When to replace your vehicle’s tires
Tires should by replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
●A tire goes flat repeatedly or c annot be properly repaired due to the
size or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
