uuBraking uBrake Assist System
Driving
Brake Assist SystemDesigned to assist the driver by generating greater braking force when you depress
the brake pedal hard during emergency braking.■
Brake assist system operation
Press the brake pedal firmly for more powerful braking.
When brake assist operates, the pedal may wiggle slightly and an operating noise
may be heard. This is normal. Keep holding the brake pedal firmly down.

uuMaintenance Under the Hood uBrake Fluid
Maintenance
Brake Fluid
The fluid level should be between the MIN
and MAX marks on the side of the reservoir.
Specified fluid: Acura Heavy Duty Brake Fluid DOT 3■
Checking the Brake Fluid
1Brake Fluid
NOTICEBrake 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-Acura brake fluid can cause corrosion
and decrease the longevity of the system. Have the
brake system flushed and refilled with Acura 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 for leaks or worn brake pads as
soon as possible.

uuChecking and Maintaining Tires uDOT Tire Quality Grading (U.S. Vehicles)
Maintenance
The traction grades, from highest to lowest, are AA, A, B, and C.
Those grades represent the tire's ability to stop on wet pavement
as measured under controlled condi tions on specified
government test surfaces of asphalt and concrete. A tire marked
C may have poor traction performance.
The temperature grades are A (the highest), B, and C,
representing the tire's resistance to the generation of heat and its
ability to dissipate heat when tested under controlled conditions
on a specified indoor laboratory test wheel. Sustained high
temperature can cause the material of the tire to degenerate and
reduce tire life, and excessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of performance which
all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel than the minimum
required by law.■
Traction
■
Temperature
1 TractionWarning: The traction grade
assigned to this tire is based on
straight-ahead braking traction tests,
and does not incl ude acceleration,
cornering, hydroplaning, or peak
traction characteristics.1 TemperatureWarning: The temperature grade for
this tire is established for a tire that is
properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive loading,
either separately or in combination,
can cause heat build up and possible
tire failure.

uuIndicator, Coming On/Blinking uIf the Brake System Indicator (Red) Comes On
Handling the Unexpected
If the Brake System Indicator (Red) Comes On
■
Reasons for the indicator to come on
• The brake fluid is low.
• There is a malfunction in the brake system.
■
What to do when the indicator comes on while driving
Press the brake pedal lightly to check pedal pressure.
• If normal, check the brake fluid level the next time you stop.
• If abnormal, take immediate action. If necessary, downshift the
transmission to slow the vehicle using engine braking.
If the EPS System Indicator Comes On
■
Reasons for the indicator to come on
• Comes on when there is a problem with EPS system.
• If you depress the accelerator pedal repeatedly to increase the engine
speed while the engine is idling, the indicator comes on, and
sometimes the steering wheel becomes harder to operate.
■
What to do when the indicator comes on
Stop the vehicle in a safe place and restart the engine.
If the indicator comes on and stays on, immediately have your vehicle
inspected by a dealer.
1 If the Brake System Indicator (Red) Comes On
Have your vehicle repaired immediately.
It is dangerous to drive with low brake fluid. If there
is no resistance from the brake pedal, stop
immediately in a safe place. If necessary downshift
the gears.
If the brake system indicator and ABS indicator come
on simultaneously, the electronic brake distribution
system is not working. This can result in vehicle
instability under sudden braking.
Have your vehicle inspected by a dealer immediately.

1 If the EPS System Indicator Comes On
NOTICEIf you repeatedly turn the steering wheel at an
extremely low speed, or hold the steering wheel on
the full left or right position for a while, the system
heats up. The system goes into a protective mode,
and limits its performance. The steering wheel
becomes harder and harder to operate. Once the
system cools down, EPS system is restored. Repeated
operation under these conditions can eventually
damage the system.
