*1: If you drive primarily in urban areas that have high concentrations of soot in the air from industry and  from diesel-powered vehicles, replace the dust and pollen filter every 15,000 miles.
*2: Driving in mountainous areas at very low vehicle speeds results in higher transmission temperatures.  This requires transmission fluid changes more frequently than recommended by the Maintenance 
Minder. If you regularly drive your vehicle under these conditions, have the transmission fluid changed 
every 31,250 miles.
*3: If a Maintenance Minder message does not appear more than 12 year after the display for item 5 is  reset, change Fuel Cell Insulating Fluid with “Fuel Cell Insulating Fluid - 50% prediluted formulation” 
every 12 years.

Maintenance
Winter Tires
If driving on snowy or frozen roads, mount all season marked  M+S tires, snow tires, 
or tire chains; reduce speed; and maintain su fficient distance between vehicles when 
driving.
Be particularly careful when operating  the steering wheel or brakes to prevent 
skidding.
Use tire chains, snow tires, or all season ti res when necessary or according to the law.
When mounting, refer to  the following points.
For winter tires:
• Select the size and load ranges that  are the same as the original tires.
• Mount the tires to all four wheels.
For tire chains:
• Install them on the front tires only.
• Because your vehicle has limited tire cl earance, we strongly recommend using the 
chains listed below:
• Follow the chain manufacturer’s instruction when installing. Mount them as 
tightly as you can.
• Check that the chains do not to uch the brake lines or suspension.
• Drive slowly.

NOTICE
Traction devices that are th e wrong size or improperly 
installed can damage your  vehicle’s brake lines, 
suspension, body, and wheels.  Stop driving if they are 
hitting any part  of the vehicle.
When tire chains are mounted, follow the chain 
manufacturer’s instructi ons regarding vehicle 
operational limits.
If your vehicle is equipp ed with summer tires, be 
aware that these tires are not designed for winter 
driving conditions. For more information, contact an 
authorized Honda Clarit y Fuel Cell dealer.
3WARNING
Using the wrong chains, or not properly 
installing chains, can damage the brake 
lines and cause a crash in which you can be 
seriously injured or killed.
Follow all instructions in this owner’s 
manual regarding the selection and use of 
tire chains.
