Why do I hear a screeching
sound when I apply the
brake pedal?The brake pads may need to be replaced. Have your vehicle
inspected by a dealer.
Unleaded premium
gasoline with a Pump
Octane Number (PON) of
91 or higher is
recommended. Is it
possible to use unleaded
gasoline with a Pump
Octane Number (PON) of
87 or lower on this vehicle?
Use of a lower octane gasoline can cause occasional metallic
knocking noise in the engine and will result in decreased engine
performance.
Use of a gasoline with a pump octane less than 87 can lead to
engine damage.Models without capless fuel filler

uuBraking uBrake System
Driving
u To confirm that the parkin g brake is applied, check if the parking brake and
brake system indicator (red) is on.
Your vehicle is equipped with disc brakes at all four wheels. A vacuum power assist
helps to reduce the effort needed on th e brake pedal. 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.

■Brake squeal
To satisfy the performance under a wide range of driving conditions, a
highperformance braking system is equipped on your vehicle. You may hear the
brake squeal under certain conditions, such as vehicle speed, deceleration, humidity,
and so on. This is not a malfunction.
■Foot Brake1 Foot 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.
Constantly using the brake pedal while going down a
long hill builds up heat, which reduces the brake
effectiveness. Apply engine braking by taking your
foot off the accelerator pe dal and downshifting to a
lower gear/speed position. With manual transmission
use a lower gear for gr eater engine braking.
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.

The fluid level should be between the MIN
and MAX marks on the side of the reserve
tank.
The brake fluid reserve tank is also used for
your vehicle's clutch fluid. As long as you keep
the brake fluid level as in structed above, there
is no need for checking the clutch fluid level.
Specified fluid: Honda Heavy Duty Brake Fluid DOT 3
■Checking the Brake Fluid
1Brake/Clutch* Fluid
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.
