Checking the coolant level  
engine fluids  
When the engine is cold, visually inspect  
the translucent coolant reservoir.  
The amount of coolant is satisfactory if  
the level is between the "FULL" and  
"LOW" marks on the tank. If the fluid level  
is low, add coolant.  
(Coolant Type - See "Selecting Coolant  
Type" below.)  
The coolant level in the reservoir will fluctuate  
depending on the engine temperature.  
Petrol engine –  
However, if the level is at or below the "LOW"  
line, add coolant. Add the coolant to the  
"FULL" line.  
To ensure excellent lubrication performance  
for your engine, Toyota recommends "Toyota  
Genuine Motor Oil" which has been specially  
tested and approved for all Toyota engines.  
Diesel engine –  
However, if the level is below the "LOW" line,  
add coolant. Add coolant between the "FULL"  
and "LOW" marks.  
For more details on "Toyota Genuine Motor  
Oil" please contact any authorized Toyota  
dealer or service center. Other engine oils of  
the same quality can also be used.  
If the coolant level drops within a short time  
after topping up, the coolant may be leaking  
through leaks in the system. Visually inspect  
the radiator, hoses, radiator cap, drain cock  
and water pump.  
If no leakage is detected, have the cap  
pressure and cooling system checked for  
leaks by any authorized Toyota dealer or  
service center, or another properly qualified  
and equipped professional.  
WARNING  
When the engine is hot, do not remove  
the radiator cap (gasoline engine), or  
the coolant tank cap or breather valve  
(diesel engine) to avoid burns.  
Diesel engine - If replacement is necessary, take the  
vehicle to any authorized Toyota dealer or workshop, or  
to another properly qualified and equipped professional.

phosphate and organic acids.)

coolant and 50% deionized water. This coolant provides  
protection down to approximately -35°C.
