NOTICERelease the parking brake fully before driving. The
rear brakes and axle can be damaged if you drive
with the parking brake applied.
If you start driving without fully releasing the parking
brake, a buzzer sounds as a warning, and RELEASE

display.
Always apply the parking brake when parking.
To prevent the parking brake from freezing when the
outside temperature is extremely cold, do not apply
it, but do the following:
Put the shift lever in

uuBrakinguBrake System
Driving
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
1Foot 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.

uuBrakinguABS (Anti-lock Brake System)
Driving
ABS (Anti-lock Brake System)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 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.
■
ABS
1ABS (Anti-lock Brake System)
NOTICEThe 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 the ABS:•When driving on rough road surfaces, including
when driving on uneven surfaces, such as gravel or
snow.•When tire chains are installed.
You 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.

uuBrakinguBrake 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.

RefuelingFuel Information■
Fuel recommendation
Use of lower octane gasoline can cause occasional metallic knocking noise in the
engine and will result in decreased engine performance.
Use of gasoline with a pump octane less than 87 can lead to engine damage.
Your vehicle is designed to operate on premium unleaded gasoline with a pump
octane of 91 or higher.
If this octane grade is unavailable, regular unleaded gasoline with a pump octane of
87 or higher may be used temporally.
The use of regular unleaded gasoline can cause metallic knocking noises in the
engine and will result in decreased engine performance. The long-term use of
regular-grade gasoline can lead to engine damage.
■
Top tier detergent gasoline
Because the level of detergency and additives in gasoline vary in the market, Acura
endorses the use of “TOP TIER Detergent Gasoline” where available to help
maintain the performance and reliability of your vehicle. TOP TIER Detergent
Gasoline meets a new gasoline standard jointly established by leading automotive
manufacturers to meet the needs of today’s advanced engines.
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.Unleaded premium gasoline, pump octane number 91 or higher
1Fuel Information
NOTICEWe recommend quality gasoline containing
detergent additives that help prevent fuel system and
engine deposits. In addition, in order to maintain
good performance, fuel economy, and emissions
control, we strongly recommend, the use of gasoline
that does NOT contain harmful manganese-based
fuel additives such as MMT, if such gasoline is
available.
Use of gasoline with these additives may adversely
affect performance, and cause the malfunction
indicator lamp on your instrument panel to come on.
If this happens, contact a dealer for service.

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.■
Gasoline containing ethanol
Some gasoline today is blended with oxygenates such as ethanol. Your vehicle is
designed to operate on oxygenated gasoline containing up to 10% ethanol by
volume. Do not use gasoline containing methanol. If you notice any undesirable
operating symptoms, try another service station or switch to another brand of
gasoline.

4.Press the area indicated by the arrow to
release the fuel fill door. You will hear a
click.
5.Remove the fuel fill cap slowly. If you hear a
release of air, wait until this stops, then turn
the knob slowly to open the fuel fill cap.
6.Place the fuel fill cap in the holder.
7.Insert the filler nozzle fully.
uWhen the tank is full, the fuel nozzle will
click off automatically. This leaves space
in the fuel tank in case the fuel expands
with a change in the temperature.
8.After filling, replace the fuel fill cap,
tightening it until you hear it click at least
once.
uShut the fuel fill door by hand.
1How to Refuel
Use the master door lock switch to unlock the fuel fill
door.
The vehicle doors and fuel fill door automatically
relock if the remote unlock function is used. This can
be deactivated by briefly opening then closing the
driver’s door.
NOTICEThe fuel fill door and its latching mechanism can be
permanently damaged if the fuel fill door is forced
closed when the driver’s door is locked.
The filler nozzle automatically stops to leave space in
the fuel tank so that fuel does not overflow as a result
of changes in air temperature.
If the fuel nozzle keeps turning off when the tank is
not full, there may be a problem with the pump’s fuel
vapor recovery system. Try filling at another pump. If
this does not fix the problem, consult a dealer.
Do not continue to add fuel after the nozzle has
automatically stopped. Additional fuel can exceed
the full tank capacity.

Fuel EconomyImproving Fuel EconomyFuel economy depends on several conditions, including driving conditions, your
driving habits, the condition of your vehicle, and loading. Depending on these and
other conditions, you may or may not achieve the rated fuel economy of this vehicle.
You can optimize your fuel economy with proper maintenance of your vehicle.
Always maintain your vehicle in accordance with the messages displayed on the
multi-information display.
•Use the recommended viscosity engine oil, displaying the API Certification Seal.
•Maintain the specified tire pressure.
•Do not load the vehicle with excess cargo.
•Keep your vehicle clean. A buildup of snow or mud on your vehicle’s underside
adds weight and increases wind resistance.■
