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 Reset the oil replacement reminder light (“MAINT REQD”) or the message “OIL MAINTENANCE REQUIRED” on the multi-information display after maintenance at every 5,000 miles.3 Perform these service items only if you drive primarily under the conditions indicated. 4 Visually check the HV battery cooling intake filter for dirt or dust every 5,000 miles and clean if necessary. Clean every 20,000 miles.5 Inspect thickness measurement and disc runout.6 Refer to “Engine/Inverter Coolant” in the “Explanation of Maintenance Items” section in the back of this guide for more information.7 Not all vehicles are designed for towing.

MAINTENANCE
Engine Oil and Oil Filter
Replace the oil filter and drain and refill
the engine oil at specified intervals. For
recommended oil grade and viscosity,
refer to the Owner’s Manual.
NOTE: Your vehicle is certified with
Genuine Toyota 0W-16 motor oil. For
VEHICLES CERTIFIED FOR 0W-16 motor
oil, the oil change interval is 10,000 miles
or 12 months IF 0W-16 MOTOR OIL IS
BEING USED. If 0W-16 is not available,
0W-20 mineral oil may be used. However,
it must be replaced at a 5,000-mile or
six-month INTERVAL with 0W-16 motor oil.
For customers who primarily drive their
vehicle under any of the listed Special
Operating Conditions, the motor oil and
filter should be replaced at 5,000 miles or
six months, REGARDLESS OF THE OIL USED
(OR CERTIFICATION OF THE VEHICLE).
Exhaust Pipes and Mountings
Visually inspect the exhaust pipes, muffler
and hangers for cracks, deterioration and
damage. Start the engine and listen
carefully for any exhaust gas leakage.
Tighten connections or replace parts
as necessary.
Fuel Lines and Connections,
Fuel Tank Band and Fuel Tank
Vapor Vent System Hoses
Visually inspect for corrosion, damage,
cracks, and loose or leaking connections.
Tighten connections or replace parts
as necessary.
Fuel Tank Cap Gasket
Visually inspect for cracks, deterioration
and damage and replace if necessary.
HV Battery Cooling Intake Filter
Clean at specified intervals. Refer to “Hybrid
Battery ( Traction Battery) Air Intake Vent” in
the “Maintenance and Care” section of the
Owner’s Manual for cleaning procedure.
Nuts and Bolts on Chassis
and Body
Retighten the seat-mounting bolts and
front /rear suspension member retaining
bolts to specified torque.
Radiator, Condenser
and/or Intercooler
Inspect for debris, corrosion and signs
of damage. Have any problem repaired
immediately by a qualified technician.
