1 Inspect sealed transmissions, transfer cases and differentials for signs of leakage. If any leakage from a sealed
component is suspected, it is recommended that you have the sealed component inspected by a Toyota dealer. Inspect
power steering fluid (if equipped) and brake fluid level/condition. Inspect engine and inverter (if equipped) coolant
level/condition/freezing point. Your dealer may recommend services (Dealer-Recommended Maintenance) based on
inspection results.
2 Visually check the FC HV battery cooling intake filter for dirt or dust every 5,000 miles and clean if necessary. Clean every
20,000 miles.
3 Perform these service items only if you drive primarily under the conditions indicated.4 N ot all vehicles are designed for towing. Refer to your Vehicle Owner’s Manual for details.5 Inspect thickness measurement and disc runout.6 Replace tank (with valve) every 15 years or 180 months whichever comes first.7 Replace inverter coolant at 150,000 miles and every 50,000 miles thereafter.

• Never use water or other kinds of coolant s
as they will cause damage.
• Coolant changes are unnecessary .
• Do not reuse coolant that has been removed
from the radiator.
• Coolant is colorless.
• Consult your Toyota dealer about

Cooling Intake Filter
Inspect and clean at specified intervals.
Refer to “Cleaning the traction battery air
intake vents and filters”
in the “Maintenance

for cleaning procedures.
Hybrid Transaxle Fluid
Inspect level and replace at specified intervals.
When performing inspections, check each
component for signs of leakage. If you
discover any leakage, have it repaired by a
