15,000 miles or 18 months
Check installation of driver’s floor mat
Inspect and adjust all fluid levels1
Inspect wiper blades
Rotate tires Visually inspect brake linings/drums and brake pads/discs
Inspect the following:
_
Ball joints and dust covers
_
Brake lines and hoses
_
Cabin air filter
_
Drive shaft boots





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.
2
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.
