battery TOYOTA SIENNA HYBRID 2021 Warranties & Maintenance Guides (in English)

SAFETY PRECAUTIONS
Your Sienna has both high-voltage DC and AC systems as well as a 12-volt system. Both DC
and AC high voltage are very dangerous and can cause personal injury, severe burns, electric
shock and even fatal injury.
To avoid personal injury, please follow all caution labels attached to high-voltage parts. Do not
touch or attempt to remove or replace any high-voltage (orange-colored) wiring and connectors.
Do not touch the service plug located underneath the access hole in the console box.
If an accident occurs, do not touch any high-voltage wiring, connectors or parts such as the
inverter unit or hybrid vehicle battery assembly.
Do not touch the potassium hydroxide electrolyte that might spill or leak from the hybrid vehicle
battery as the result of an accident. If potassium hydroxide electrolyte gets on your skin or in
your eyes, neutralize it immediately with a saturated boric acid solution (ratio: 80 grams boric
acid to two liters water). Seek immediate medical attention.
If a vehicle fire occurs, extinguish it with a Class D powder-type fire extinguisher.
Toyota recommends having maintenance and repairs for your Sienna performed by
an authorized Toyota dealership. To locate your nearest authorized Toyota dealership,
contact the Toyota Brand Engagement Center at (800) 331-4331 or log on to

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.
