Braking
Brake System
Use the parking brake to keep the vehicle stationary when parked. When the
parking brake is applied, you can manu ally 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 parking brake switch up gently
and securely. u The parking brake and brake system
indicator (red) comes on.
■To release
The power mode must be in ON in order to
release the electric parking brake.
1. Depress the brake pedal.
2. Press the electric parking brake switch.
u The parking brake and brake system
indicator (red) goes off.
Manually releasing the parking brake using
the switch helps your vehicle to start slowly
and smoothly when facing downhill on steep
hills.
■Parking Brake1 Braking
When you depress the brak e pedal, you may hear a
whirring sound from the engine 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 parking brake. 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
12V-battery goes dead. 2 If the 12-Volt Battery Is Dead P. 647
If you pull up and hold the electric parking brake
switch while driving, the brakes on all four
wheels are applied by the electric servo brake
system until the vehicle come to a stop. The
electric parking brake then applies, and the
switch should be released.

Driving
Your vehicle is equipped with disc brakes at all four wh eels. The brake assist system
increases the stopping force when you depress the brake pedal hard in an
emergency situation. The anti-lock brake system (ABS) helps you retain steering
control when braking 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 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 a deal er. 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 vibr ation 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 has fully recharged,
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.

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, and helps you retain steering control by
pumping the brakes rapidly, much faster than you can.
The electronic brake distribu tion (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distribution according to vehicle loading.
You should never pump the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pe dal. This is sometimes referred to as
“stomp and steer.“
■ABS operation
The brake pedal may pulsate slightly when the ABS is working. Depress the brake
pedal and keep holding the pedal firmly do wn. On dry pavement, you will need to
press on the brake pedal very hard before th e ABS activates. However, you may feel
the ABS activate immediately if you are trying to stop on snow or ice.
ABS may activate when you depres s the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surf aces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes under 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
NOTICE
The ABS may not function correctly if you use a tire of
the incorrect size or type.
If the ABS indicator comes on while driving, there
may be a problem with the system.
While normal braking is not affected, there is a
possibility that the ABS wi ll not be operating. Have
your vehicle checked by a dealer immediately.
The ABS is not designed for the purpose of reducing
the time or distance it takes for a vehicle to stop: It is
designed to limit brake lo ckup which can lead to
skidding and loss of steering control.
In the following cases, yo ur vehicle may need more
distance to stop than a vehicle without the ABS:
•You are driving on rough or uneven road surfaces,
such as gravel or snow.
The following may be observed with the ABS system:
•Motor sounds coming from the engine
compartment when the brakes are applied, or
when system checks are being performed after the
engine has been started and while the vehicle
accelerates.
•Brake pedal and/or the vehicle body vibration when
ABS activates.
These vibrations and sounds are normal to ABS
systems and are no cause for concern.

Designed to assist the driver by generating greater braking force when you depress

NOTICE
Brake fluid marked DOT 5 is not compatible with your
vehicle's braking system and can cause extensive
damage.
If the specified br ake fluid is not av ailable, 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 a dealer inspect the vehicle for leaks or worn
brake pads as soon as possible.
