■ 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 any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional, test the cap and check for
leaks in the cooling system.
■ Coolant selection
Gasoline engine
Only use “Toyota Super Long Life C oolant” or similar high quality ethyl-
ene glycol based non-silicate, non-am ine, 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])

Improper use of the tire jack may lead to death or serious injury due to the
vehicle suddenly falling off the jack.
● Do not use the tire jack for any purpose other than replacing tires or install-
ing 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
