Maintenance and care
n
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.
n Coolant selec
tion
Only use “Toyota Super Long Life Coolant” or similar high quality ethylene
glycol based n
on-silicate, non-amine, non-nitrite and non-borate coolant with
long-life hybrid organic acid technology.
Except Canada:“Toyota Super Long Life Coolant” is a mixture of 50% cool -
ant 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
n 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.
NOTICE
nWhen adding engine coolant
Coolant is neither plain water nor strai ght 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.
n If you spill coolant
Be sure to wash it off with water to prevent damage to parts or paint.

indicators is shown by the
“TWI” or “” marks, etc.,
molded on the sidewall of
ea
ch tire.
Check spare tire condition
an
d inflation pressure if not
rotated.
n Tire rotation
Rotate the tires in the order
show

To equalize tire wear and
extend tire life, Toyota recom -
mends that tire rotation is
ca
rried out at the same inter -
val as tire inspection.
n The tire pressure warning system
Your Toyota is equipped with a tire pressure warning system that
use

Maintenance and care
Ti
Installing tire pressure warning valves and transmitters
When replacing tires or wheels, ti re pressu
re 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
sy
stem must be initialized. Have tire pressure warning valve and trans -
mitter ID codes registered by your Toyota dealer.
Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a ti re pressure warning valve and
transmitter, it is necessary to register the ID code of tire pressure
warning valve and transmitter. Have the ID code registered by your
Toyota dealer.
nWhen to replace your vehicle's tires
Tires should be replaced if:
lYou have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
lA 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.
nReplacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pre ssure w

arning system will not work properly. After
driving for about 20 minutes, the ti re pressure warning light comes on
after blinking for 1 minute to indicate a system malfunction.
nTire life
Any tire over 6 years old must be checked by a qualified technician even
if

they have seldom or never been used or damage is not obvious.
