uuBraking uBrake System
Driving
Your vehicle is equipped with disc brakes at all four wheels. 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.2 Brake Assist System P. 403

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 your 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.
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.

Keeps the brake applied after releasing the brake pedal until the accelerator pedal is
pressed. You can use this system while the vehicle is temporarily stopped, such as
when you stop at a traffic light.■

death.
Never activate the automatic brake hold
system or rely on it to keep a vehicle from
moving when stopped on a steep hill or
slippery roads.

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)Helps prevent the wheels from locking up, and help s 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
1 Anti-lock Brake System (ABS)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 your
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 immediatel y after starting the engine or
while driving. This is normal.

4. Turn off the engine.
u The electric parking brake indicator goes off in about 15 seconds.
Always confirm the electric parking brake is set, particularly if you are parked on an
incline.
1 Parking Your Vehicle
Do not park your vehicle near flammable objects,
such as dry grass, oil, or timber.
Heat from the exhaust can cause a fire.1When StoppedNOTICEThe following can damage the transmission:•Depressing the accelerator and brake pedals
simultaneously.•Changing into
(P before the vehicle stops
completely.
When facing uphill, do not hold the vehicle by
depressing the accelerator pedal.
Doing so may cause the items to malfunction or a fire
inside the vehicle.
Raise the wiper arms when snow is expected.

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.■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 lev el 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 in formation for your vehicle, or on information on
gasoline that does not contain MMT, visit Acura Owners 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.■Fuel tank capacity: 17.2 US gal (65 liters)Unleaded premium gasoline, pump octane number 91 or higher
1Fuel InformationNOTICEWe 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.
Some gasoline today is blended with oxygenates such
as ethanol. Your vehicle is designed to operate on
oxygenated gasoline containing up to 15% 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.

uuRefueling uHow to Refuel
Driving
How to RefuelYour fuel tank is not equipped with a fuel fill cap. You can insert the filler nozzle
directly into the filler pipe. The tank seals itself again when you pull out the filler
nozzle.
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. Press the fuel fill door release button.
u The fuel fill door opens.
4. Place the end of the filler nozzle on the
lower part of filler opening, then insert it
slowly and fully.
u Make sure that the end of the filler
nozzle goes down along with the filler
pipe.
u Keep the filler nozzle level.
u When the tank is full, the filler nozzle will
click off automatically.
u After filling, wait about five seconds
before removing the filler nozzle.
5. Shut the fuel fill door by hand.
1How to Refuel
Only a service station filler nozzle can be used.
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 af ter the nozzle has
automatically stopped. Additional fuel can exceed
the full tank capacity.
If you have to refuel your vehicle from a portable
container, use the funnel provided with your vehicle. 2 Refueling From a Portable Fuel Container

WARNING
Gasoline is highly flammable and explosive.
You can be burned or seriously injured
when handling fuel.
• Stop the engine, and keep heat, sparks,
and flame away.
• Handle fuel only outdoors.
• Wipe up spills immediately.

422Driving
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.■
