Driving
Foot Brake
Your vehicle is equipped with disc brakes at all four wheels. A power assist helps
reduce the effort needed on the brake pedal. 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 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, the brake pads need to
be replaced. Have the vehicle checked by a dealer.
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 pedal and downshifting to
a lower gear. With manual transmission use a lower
gear for greater 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 confuse drivers behind you.

ABS (Anti-lock Brake System)
212Driving
ABS (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.
The electronic brake distribution (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 pedal. This is sometimes referred to as
"stomp and steer."
ABS (Anti-lock Brake System) NOTICE The ABS may not function correctly if you use an
incorrect tire type and size.
When 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 of the ABS not operating. Have the
vehicle checked by a dealer immediately.
The ABS does not reduce the time or distance it
takes to stop the vehicle. It only helps with steering
control during hard braking.
In the following cases, your vehicle may need more
stopping distance than a vehicle without ABS:
When driving on rough road surfaces, including twhen driving on uneven surfaces, such as gravel
or snow.
When tire chains are installed. tYou may hear a motor sound coming from the
engine compartment while system checks are being
performed immediately after starting the engine or
while driving. This is normal.
ABS operation
The brake pedal may pulsate slightly when the ABS is working. Keep holding the
pedal firmly down. On dry pavement, you will need to press on the brake pedal
very hard before the ABS activates. However, you may feel the ABS activate
immediately if you are trying to stop on snow or ice.
When the vehicle speed goes under 6 mph (10 km/h), the ABS stops.

Refueling
How to Refuel
216Driving
How to Refuel
1. Stop your vehicle with the service station
pump on the left side of the vehicle in the
rear.
2. Turn off the engine.
3. Unlock the driver's door using the master
door lock switch.
The fuel fill door on the outer side of
the vehicle will unlock.
How to Refuel
WARNING
Gasoline is highly flammable and
explosive. You can be burned or seriously
injured when handling fuel.
Stop the engine, and keep heat, sparks, t
and flame away.
Handle fuel only outdoors. t
Wipe up spills immediately. t
Qualifying gasoline retailers will, in most cases, identify their gasoline as having
met "TOP TIER Detergent Gasoline" standards at the retail location. This fuel
is guaranteed to contain the proper level of detergent additives and be free of
metallic additives. The proper level of detergent additives, and absence of harmful
metallic additives in gasoline, help avoid build-up of deposits in your engine and
emission control system.
For further important fuel-related information for your vehicle, or on information
on gasoline that does not contain MMT, visit My Acura at owners.acura.com In
Canada, visit www.acura.ca for additional information on gasoline. For more
information on top tier gasoline, visit www.toptiergas.com.

from diesel-powered vehicles, replace the dust and pollen filter every 15,000 miles (24,000 km).
Maintenance Service Items
Independent of the Maintenance Minder tinformation, replace the brake fluid every 3 years.

Maintenance
Tire and Wheel Replacement
Tire and Wheel Replacement
Replace your tires with radials of the same size, load range, speed rating, and
maximum cold tire pressure rating (as shown on the tire’s sidewall). Using tires of a
different size or construction can cause the ABS and VSA
® (vehicle stability assist)
system to work incorrectly.
It is best to replace all four tires at the same time. If that isn’t possible, replace the
front or rear tires in pairs.
If you replace a wheel, only use TPMS specified wheels approved for your vehicle.
Make sure that the wheel’s specifications match those of the original wheels.
WARNING
Installing improper tires on your vehicle
can affect handling and stability. This can
cause a crash in which you can be seriously
hurt or killed.
Always use the size and type of tires
recommended in this owner’s manual.

If the Brake System Indicator Comes On
292Handling the Unexpected
If the Brake System Indicator Comes On
Reasons for the indicator to come on
The brake fluid is low. t
There is a malfunction in the brake system. t 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. t
If abnormal, take immediate action. If necessary, downshift the t
transmission to slow the vehicle using engine braking.
If the Brake System Indicator 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 brake distribution
system is not working. This can result in vehicle
instability under sudden braking.
Have your vehicle inspected by a dealer immediately.
U.S.
CanadaIf the EPS Indicator Comes On
Reasons for the indicator to come on
Comes on when there is a problem with EPS. t
If you depress the accelerator pedal repeatedly to increase the t
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.
If the EPS Indicator Comes On NOTICE If 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 is restored. Repeated
operation under these conditions can eventually
damage the system.
