Additional Maintenance Items for Special Operating Conditions2
Driving on dirt roads or dusty roads:Replace fuel cell air filter
Tighten nuts and bolts on chassis and body
Extensive idling and/or low speed driving for a long distance such as police, taxi or
door-to-door delivery use:
Inspect hydrogen supply system for leaks and damage
Inspect hydrogen tank (with valve) for leaks and damage
Inspect hydrogen tank band for damage
Driving while towing, using a car-top carrier, or heavy vehicle loading:3
Tighten nuts and bolts on chassis and body
Operating on rough or muddy roads, or roads with melted snow:Inspect hydrogen supply system for leaks and damage
Inspect hydrogen tank (with valve) for leaks and damage
Inspect hydrogen tank band for damage
NOTE: Driving in heavy traffic, on dirt roads or in urban, dusty or desert areas may shorten
the life of the cabin air filter. Replacement may be needed if you notice reduced air flow
from the air conditioner and heater or if the windows fog easily when you use the “Fresh”
mode. Consult your dealer if any of these conditions occur.
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.

Perform these service items only if you drive primarily under the conditions indicated.3
Not all vehicles are designed for towing. Refer to your Vehicle Owner’s Manual for details.

MAINTENANCE
Fuel Cell Air Filter
Inspect or replace at specified intervals.
When performing inspections, check for
damage, excessive wear and oiliness,
and replace if necessary.
Fuel Cell Coolant
Inspect at specified intervals. When performing
inspections, check that the coolant level is
between the “FULL” and “LOW” lines on the
see-through reservoir tank.
Notice: A qualified technician should perform
this operation.
Use the following product:
“Toyota Genuine FC Stack Coolant.”
• In order to safely cool the fuel cell
stack, which is at high voltages, the
fuel cell stack coolant is an exclusive
high insulation product.
• Never use water or other kinds of coolants
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
replenishing or changing the fuel cell
stack coolant.
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
qualified technician immediately.
Hydrogen Sensors
Inspect both hydrogen sensors at specified
intervals. This inspection should be performed
using calibration gas at a concentration of
1.3% hydrogen.
Notice: A qualified technician should perform
this operation.
Hydrogen Tank (with Valve)
NOTE: Replace every 15 years or
180 months, whichever comes first.
Notice: A qualified technician should
perform this operation.

MAINTENANCE
EXPLANATION OF MAINTENANCE ITEMS
Inverter Coolant
Drain the cooling system and refill with an
ethylene-glycol type coolant. Inspect hoses
and connections for corrosion and leaks.
Tighten connections and replace parts
when necessary.
Inspect at specified intervals. When performing
inspections, check that the coolant level is
between the “FULL” and “LOW” lines on the
see-through reservoir tank.
Notice: A qualified technician should perform
this operation.
Use the following product:
“Genuine Toyota Super Long-Life Coolant.”
NOTE: Replace inverter coolant at 150,000
miles and every 50,000 miles thereafter.
Ion Exchanger Element
It is necessary to replace the element within
the Ion Exchanger assembly periodically in
order to prevent degradation of the electrical
generating efficiency of the FC stack.
Notice: A qualified technician should perform
this operation.
Nuts and Bolts on Chassis
and Body
Retighten the seat-mounting bolts and
front/rear suspension member retaining
bolts to specified torque.
Radiator, Condenser, Hoses
and/or Intercooler
Inspect for damage, debris, corrosion,
kinks, cracks, rot, clogging and leaks.
Have any problem repaired immediately
by a qualified technician.
Steering Gear
Inspect for signs of leakage. If you
discover any leakage, have it repaired
immediately by a qualified technician.
Steering Linkage and Boots
With the vehicle stopped, check for
excessive freeplay in the steering wheel.
Inspect the linkage for bending and
damage and the dust boots for
deterioration, cracks and damage.
Replace any damaged parts. A qualified
technician should perform these operations.
Tire Rotation
Tires should be rotated according to the
instructions in the Owner’s Manual. When
rotating tires, check for damage and
uneven wear. Replace if necessary.
Wiper Blades
The wiper blades should not show
any signs of cracking, splitting, wear,
contamination or deformation. The
wiper blades should clear the windshield
without streaking or skipping.
