Maintenance and care
AYGO_OM_Europe_OM99Q24E
WARNING
■When working near the electric cooling fans or radiator grille
Vehicles without a smart entry & start system
Be sure the engine switch is off. With the engine switch in the “ON” position,
the electric cooling fan may automatical ly start to run if the air conditioning
is on and/or the coolant temperature is high. ( P. 338)
Vehicles with a smart entry & start system
Be sure the engine switch is off. With the engine switch in IGNITION ON
mode, the electric cooling fan may automatically start to run if the air condi-
tioning is on and/or the coolant temperature is high. ( P. 338)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.,
from getting in your eyes.
NOTICE
■ If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.
■ If the fluid level is low or high
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.
If the reservoir needs frequent refilling, it may indicate a serious problem.

schedule. In dusty areas or areas with heavy traffic flow, early replacement
may be required. (For scheduled maintenance information, please refer to the
“Toyota Service Booklet” or “Toyota Warranty Booklet”.)
■ If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
The air conditioning filter must be changed regularly to maintain
air conditioning efficiency.

■After a fuse is replaced
● If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. ( P. 365)
● If the replaced fuse blows again, have the vehicle inspected by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
■ If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.

WARNING
■ To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage to the vehicle, and possibly a fire or
injury.
● Never use a fuse of a higher amperage rating than that indicated, or use
any other object in place of a fuse.
● Always use a genuine Toyota fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
● Do not modify the fuses or fuse boxes.
NOTICE
■Before replacing fuses
Have the cause of electrical overload determined and repaired by any
authorized Toyota dealer or repairer, or another duly qualified and equipped
professional as soon as possible.
