The coolant level is satisfactory if it is between the “FULL” a nd “LOW”
lines on the reservoir wh en the engine is cold.
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the
“LOW” line, add coolant up to the
“FULL” line.
■ Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-bora te coolant with
long-life hybrid organic acid technology.
For the U.S.A.: “Toyota Super Long Life Coolant” is a mixture o f 50% cool-
ant and 50% deionized water. (Minimum temperature: -31 F
[-35 C])
For Canada: “Toyota Super Long Life Coolant” is a mixture of 55 % cool-
ant and 45% deionized water. (Minimum temperature: -44 F
[-42 C])
For more details about engine coolant, contact your Toyota deal er.
■ If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir ca ps, 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.

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 coolant
Coolant is neither plain water nor straight antifreeze. The cor rect 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.

tires are cold, and cond uct initialization again.
■Warning performance of the tire pressure warning system
The warning of the tire pressu re warning system will change in accor-
dance with driving conditions. F or this reason, the system may give a
warning even if the tire pressure does not reach a low enough l evel, or if
the pressure is higher than the pressure that was adjusted to w hen the
system was initialized.
■When initialization of the tire pressure warning system has fai led
Initialization can be completed i n a few minutes. However, in the following
cases, the settings have not been record ed and the system will not oper-
ate properly. If repeated attempts to record tire inflation pre ssure settings
are unsuccessful, have the vehicl e inspected by your Toyota dealer.
●When operating the initialization of the system, the tire pressure warning
light does not blink 3 times and the setting message does not a ppear on
the multi-information display.
●After driving for a certain period of time since the initializa tion has been
completed, the warning light comes on after blinking for 1 minute.
