Life Coolant”, which has been tested to  
ensure that it will not cause corrosion nor  
result in malfunction of your engine

To check the fluid level, simply look at  
the seethrough reservoir. The level  
should be between the “MAX” and  
“MIN” lines on the reservoir.  
It is normal for the brake fluid level to go  
down slightly as the brake pads wear or  
when the fluid level in the accumulator is  
high.

designed to avoid engine cooling system  
malfunction on Toyota vehicles.  
If the reservoir needs frequent refilling, it  
may indicate a serious mechanical prob-  
lem.  
Please contact your Toyota dealer for  
further details.  
If the level is low, add SAE J1703 or

Refilling brake fluid:  
NOTICE  
1. Turn the engine switch off.  
If cold O.K.  
If hot O.K.  
If you spill some of the fluid, be sure  
to wipe it off to prevent it from dam-  
aging the parts or paintwork.  
2. Depress the brake pedal more than 20  
times (until the brake pedal resistance  
decreases and pedal travel increases).

Use only newly opened brake fluid. Once  
opened, brake fluid absorbs moisture from  
the air, and excess moisture can cause a  
dangerous loss of braking.  
Check the fluid level through the reser-  
voir. If necessary, add automatic trans-  
mission fluid DEXRONrII or III.  
CAUTION  
If the vehicle has been driven around 80  
km/h (50 mph) for 20 minutes (a little  
more in frigid temperatures), the fluid is  
hot (60_C—80_C or 140_F—175_F). You  
may also check the level when the fluid  
Take care when filling the reservoir  
because brake fluid can harm your  
hands or eyes. If fluid gets on your  
hands or in your eyes, flush the af-  
fected area with clean water immedi-  
ately. If you still feel uncomfortable  
with your hands or eyes, go to the  
doctor.
