If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, engine coolant filler cap, radiator cap,
drain cock and water pump.
If you cannot find a leak, have any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional, test the cap and check for
leaks in the cooling system.
Coolant selection
Only use “Toyota Super Long Life Coolant” or similar high-quality eth-
ylene 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%
deionized water. (Enabled: -35C [-31F])
For more details about engine coolant, contact any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional.
CAUTION
When the engine is hot
Do not remove the radiator cap (IS250), or the coolant reservoir cap (IS220d
and IS200d).
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.

CAUTION
Using the tire jack
Improper use of the tire jack may lead to death or serious injuries due to the
vehicle suddenly falling off the jack.
Do not use the tire jack for any purpose other than replacing tires or
installing and removing tire chains.
Only use the tire jack that comes with this vehicle for replacing a flat tire.
Do not use it on other vehicles, and do not use other tire jacks for replac-
ing tires on this vehicle.
Always check that the tire jack is securely set to the jack point.
Do not put any part of your body under the vehicle supported by a jack.
Do not start or run the engine while your vehicle is supported by the jack.
Do not raise the vehicle while someone is in it.
When raising the vehicle, do not put an object on or under the jack.
Do not raise the vehicle to a height greater than that required to replace the
tire.
Use a jack stand if it is necessary to get under the vehicle.
Take particular care when lowering the vehicle to ensure that no one work-
ing on or near the vehicle may be injured.
Replacing a flat tire
Do not attach a heavily damaged wheel ornament, as it may fly off the
wheel while the vehicle is moving.
Failure to follow these precautions could cause the wheel nuts to loosen
and the tire to fall off, resulting in death or serious injury.
• Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can
cause the wheel nuts to loosen and the wheel may fall off, causing a
serious accident. Remove any oil or grease from the wheel bolts or
wheel nuts.
• Have the wheel nuts tightened with a torque wrench to 103 N
•m (10.5
kgf
•m, 76 ft•lbf) as soon as possible after changing wheels.
