Driving
If there is a strong impact with something  under the vehicle, stop in a safe location. 
Check the underside of the vehicle for da mage or any fluid leaks, and contact an 
authorized Hond a Clarity Fuel Cell dealer.
Transmission
As with a conventional gasoline-powered  vehicle with an automatic transmission, 
this vehicle will creep.
Keep the brake pedal firmly  depressed when stopped.
■Other Precautions
■Creeping
1Precautions While Driving
Do not press the 
(N button, as you will lose 
regenerative braking (and ac celeration) performance.
Avoid hard braking for the  first 200 miles (300 km).
You should also follow this  when the brake pads are 
replaced.

uuBraking uBrake System
Driving
Your vehicle is equipped with disc brakes at  all four wheels. The brake assist system 
increases the stopping force when you  depress the brake pedal hard in an 
emergency situation. The an ti-lock brake system (ABS) helps you retain steering 
control when brak ing very hard.

Check the brakes after driving through deep water, 
or if there is a buildup of road surface water. If 
necessary, dry the brakes by  lightly depressing the 
pedal several times.
If you hear a continuous me tallic friction sound when 
applying the brakes, this is  caused by the brake wear 
indicator rubbing on the  brake rotor and indicates 
that the brake pads need to be replaced. Have the 
vehicle checked by an authorized Honda Clarity Fuel 
Cell dealer. If you hear onl y an occasional squeak or 
squeal when you initially a pply the brake pedal, this 
may be normal and caus ed by high frequency 
vibration of the brake pads  against the rotating brake 
disc.
Constantly using the brak e pedal while going down a 
long hill builds up heat, which reduces the brake 
effectiveness.
To help reduce heat build -up in the brakes when 
descending a long slope, use regenerative braking to 
slow the vehicle down.
When the high voltage battery is recharging, 
regenerative braking  may not be possible.

P. 118
Do not rest your foot  on the brake pedal while 
driving, as it will lightly  apply the brakes and cause 
them to lose effectiveness  over time and reduce pad 
life. It will also conf use drivers behind you.

Maintenance
Transmission Fluid
Have an authorized Honda Clarity Fuel Cell  dealer check the fluid level and replace 
if necessary.
Do not attempt to check or change  the transmission fluid yourself.
Brake Fluid
The fluid level should be between the  MIN 
and  MAX  marks on the side of the reserve 
tank.
■Transmission Fluid
Specified fluid: Honda ATF DW-1 (automatic transmission fluid)
Specified fluid: Honda He avy Duty Brake Fluid DOT 3
■Checking the Brake Fluid
1Transmission Fluid
NOTICE
Do not mix Honda ATF DW-1 with other 
transmission fluids.
Using a transmission flui d other than Honda ATF 
DW-1 may adversely af fect the operation and 
durability of your vehicle’ s transmission, and damage 
the transmission.
Any damage caused by usi ng a transmission fluid that 
is not equivalent to Honda ATF DW-1 is not covered 
by Honda’s new vehicle limited warranty.
1 Brake Fluid
NOTICE
Brake fluid marked DOT 5 is  not compatible with your 
vehicle’s braking system  and can cause extensive 
damage.
If the specified brake fluid is not available, you should 
use only DOT 3 or DOT 4 fluid from a sealed 
container as a temporary replacement.
Using any non-Honda brake fluid can cause corrosion 
and decrease the longevity of the system. Have the 
brake system flushed and re filled with Honda Heavy 
Duty Brake Fluid DOT 3 as soon as possible.
If the brake fluid level is at or below the MIN  mark, 
have an authorized Honda Clarity Fuel Cell dealer 
inspect the vehicle for leaks or worn brake pads as 
soon as possible.
