Brake System
Use the parking brake to keep the vehicle stationary when parked. When the
parking brake is applied, you can ma nually or automatically release it.
■To apply
The electric parking brake can be applied any
time the vehicle has battery, no matter which
position the power mode is in.
Pull the electric parkin g brake switch up gently
and securely.
u The parking brake and brake system
indicator (red) comes on.
■Parking Brake1Brake System
When you depress the brak e pedal, you may hear a
whirling sound from the moto r compartment. This is
because the brake system is in operation, and it is
normal.
1 Parking Brake
You may hear the electric parking brake system
motor operating from the re ar wheel area when you
apply or release the parki ng brake, or set the power
mode to OFF. This is normal.
The brake pedal may slightly move due to the electric
parking brake system opera tion when you apply or
release the parking br ake. This is normal.
You cannot apply or release the parking brake if the
12-volt battery goes dead. 2 Jump Starting P. 514
If you pull up and hold the electric parking brake
switch while driving, the brakes on all four
wheels are applied by the VSA ® system until the
vehicle comes to a stop. The electric parking
brake then applies, and the switch should be
released.

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.

■Foot Brake1Foot Brake
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 metallic 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 Electric
dealer. If you hear only an occasional squeak or squeal
when you initially apply the brake pedal, this may be
normal and caused by high frequency vibration of the
brake pads against the rotating brake disc.
Applying constant pressure to the brakes while going
down a long hill can cause the brakes to heat up,
resulting in a loss of stopping power. Therefore,
when descending a long hill , release the accelerator
pedal and allow regenerati ve braking to slow the
vehicle down. To adjust the rate of deceleration, use
the deceleration paddle selector.
When the high voltage battery is recharging,
regenerative braking may not be possible.

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.
