z Remember that battery and ignition  
cables carry high currents or volt-  
ages. Be careful of accidentally  
causing a short circuit.  
D Right after driving, the engine  
compartment—the engine, radiator,  
exhaust manifold and spark plug  
boots, etc.—will be hot. So be care-  
ful not to touch them. Oil, fluids  
and spark plugs may also be hot.  
D Use eye protection whenever you  
work on or under your vehicle  
where you may be exposed to flying  
or falling material, fluid spray, etc.  
z Add only “Toyota Super Long Life  
Coolant” or similar high quality eth-  
ylene glycol based non−silicate,  
non−amine, non−nitrite, and non−bo-  
rate coolant with long−life hybrid  
organic acid technology to fill the  
radiator. “Toyota Super Long Life  
Coolant” is pre−mixed with 50%  
coolant and 50% deionized water.  
D Used engine oil contains potentially  
harmful contaminants which may  
cause skin disorders such as in-  
flammation or skin cancer, so care  
should be taken to avoid prolonged  
and repeated contact with it. To re-  
move used engine oil from your  
skin, wash thoroughly with soap  
and water.  
D If the engine is hot, do not remove  
the radiator cap or loosen the drain  
plugs to prevent burning yourself.  
D Do not leave anything that may  
burn easily, such as paper or rags,  
in the engine compartment.  
z If you spill some of the coolant, be  
sure to wash it off with water to  
prevent it from damaging the parts  
or paint.  
D Do not smoke, cause sparks or al-  
low open flames around fuel or the  
battery. Their fumes are flammable.  
D Do not leave used oil within the  
reach of children.  
D Dispose of used oil and filter only  
in a safe and acceptable manner.  
Do not dispose of used oil and fil-  
ter in household trash, in sewers or  
onto the ground. Call your dealer or

ways use automotive jack stands or  
other solid supports.
