The coolant level is satisfactory if it is between the “F” and “L” lines on the reser-
voir when the engine is cold.
Reservoir cap
“F”
“L” If the level is on or below the “L” line, add
coolant up to the “F” 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-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 % deion-
ized water. (Minimum temperature: -31  F [-35  C])
Canada: “Toyota Super Long Life Coolant” is a mixture of 55 % coolant and 45 % deion-
ized water. (Minimum temperature: -44  F [-42  C])
For more details about engine coolant, contact your Lexus dealer. ■
If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir caps, drain cock and water
pump. If you cannot find a leak, have your Le xus dealer test the cap and check for leaks in
the cooling system.Engine coolant 1

When the engine is hot
Do not remove the radiator cap, or 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.

Maintenance and care Check the radiator and condenser and clear any foreign objects.
If either of the above parts is extremely dirty or you are not sure of their condi-
tion, have your vehicle checked by your Lexus dealer.

Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN” lines
on the tank. NOTICE ■
When adding 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 cool-
ing. Be sure to read the antifreeze or coolant label. ■
If you spill coolant
Be sure to wash it off with water to pr event it from damage to parts or paint.
Radiator and condenser WA R N I N G ■
When the engine is hot
Do not touch the radiator or condenser as they may be hot and cause serious injuries,
such as burns.

Add coolant if necessary. Water can be used in an emergency if
coolant is unavailable.
Start the engine and turn the air conditioning system on to check that the air
conditioning condenser cooling fans op erate and to check for coolant leaks
from the radiator or hoses. The fans operate when the air conditioning system is turned on immediately after a
cold start. Confirm that the fans are oper ating by checking the fan sound and air flow.
If it is difficult to check th ese, turn the air conditioning system on and off repeatedly.
(The fans may not operate in freezing temperatures.)
If the fans are not operating:
Stop the engine immediately and contact your Lexus dealer.
If the fans are operating:
Have the vehicle inspected at the nearest Lexus dealer. 4
