uuBraking uBrake System
Driving
Your vehicle is equipped with disc brakes at all four wheels. A vacuum 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 Brake1Foot 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 brak e 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.
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.

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, an d 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 distri bution 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 pe dal. 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 unde r 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
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 ti me or distance it takes
to stop the vehicle. It only helps with steering control
during hard braking.
In the following cases, yo ur vehicle may need more
stopping distance than a vehicle without the ABS:
•When driving on rough road surfaces, including
when driving on uneven surf aces, 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.

Fuel 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 Deterg ent Gasoline” where available to help
maintain the performance and reliability of your vehicle. TOP TIER Detergent
Gasoline meets a new gasoline standard join tly established by leading automotive
manufacturers to meet the need s of today’s advanced engines.
Qualifying gasoline retailers will, in most ca ses, 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-rel ated information 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: 19.5 US gal (73.8 liters)
Unleaded premium gasoline, pump octane number 91 or higher
1Fuel Information
NOTICE
We recommend quality ga soline 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 reco mmend 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, a nd cause the malfunction
indicator lamp on your inst rument 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 gaso line containing methanol.
If you notice any undesira ble operating symptoms, try
another service station or sw itch to another brand of
gasoline.

Maintenance
Tire and Wheel Replacement
Replace your tires with radials of the sa me size, load range, speed rating, and
maximum cold tire pressure ra ting (as shown on the tire’s sidewall). Using tires of a
different size or construction can cause the Vehicle Stab ility Assist (VSA®) and
SH-AWD ®
* systems as well as ABS 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 sp ecified wheels approved for your vehicle.
Make sure that the wheel’s specifications match those of the original wheels.

Emergency Engine Stop
The ENGINE START/STOP button may be used to st op the engine due to an
emergency situation even while driving. If you must stop the engine, do either of the
following operations:
• Press and hold the ENGINE START/STOP button for about two seconds.
• Firmly press the ENGINE START/STOP button three times.
The steering wheel will not lock. However, because turning off the engine disables
the power assist the engine provides to the steering and braking systems, it will
require significantly more physical effort an d time to steer and slow the vehicle. Use
both feet on the brake pedal to slow down the vehicle and stop immediately in a
safe place.
The gear position auto matically changes to
(P after the vehicle comes to a complete
stop. Then, the power mode changes to VEHICLE OFF.
1Emergency Engine Stop
Do not press the button while driving unless it is
absolutely necessary for th e engine to be switched
