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 an ti-lock brake system (ABS) helps you retain steering
control when brak ing 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 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 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.
Whenever the brakes are activated by CMBS
TM or
another system that automa tically controls braking,
the brake pedal is depressed and released in
accordance with braking function.

uuBraking uAnti-lock Brake System (ABS)
Driving
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 can.
The electronic brake distribu tion (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 pe dal. This is sometimes referred to as
“stomp and steer.”
■ABS operation
The brake pedal may pulsate slightly when the ABS is working. Depress the brake
pedal and keep holding the pedal firmly do wn. On dry pavement, you will need to
press on the brake pedal very hard before th e ABS activates. However, you may feel
the ABS activate immediately if you are trying to stop on snow or ice.
ABS may activate when you depres s the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surf aces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes under 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
NOTICE
The ABS may not function correctly if you use a tire of
the incorrect size or type.
If the ABS indicator comes on while driving, there
may be a problem with the system.
While normal braking will not be affected, there is a
possibility that the ABS wi ll not be operating. Have
your vehicle checked by a dealer immediately.
The ABS is not designed for the purpose of reducing
the time or distance it takes for a vehicle to stop: It is
designed to limit brake lo ckup which can lead to
skidding and loss of steering control.
In the following cases, yo ur vehicle may need more
distance to stop than a vehicle without the ABS:
•You are driving on rough or uneven road surfaces,
such as gravel or snow.
•The tires are equipped with tire chains.
The following may be observed with the ABS system:
•Motor sounds coming from the engine
compartment when the brakes are applied, or
when system checks are being performed after the
engine has been started and while the vehicle
accelerates.
•Brake pedal and/or the vehicle body vibration when
ABS activates.
These vibrations and sounds are normal to ABS
systems and are no cause for concern.

The corner and center sensors monitor obstacles around your vehicle, and the
beeper, multi-information display and audi o/information screen let you know the
approximate distance between your vehicle and the obstacle.
■The sensor location and range
1 Parking Sensor System*
Even when the system is on, always confirm if there is
no obstacle near your ve hicle before parking.
The system may not work properly when:
•The sensors are covered with snow, ice, mud, or
dirt.
•The vehicle has been out in hot or cold weather.
•There is something nearby that emits ultrasonic
waves or high frequency sounds.
•Driving in bad weather (rain, fog, snow, etc.).
•Any accessories have been put on or around the
sensors.
The system may not de tect these obstacles:
•Thin or low objects.•Sonic-absorptive materials, such as snow, cotton,
or sponge.
•Objects directly under the bumper.
The system may falsely de tect obstacles in the
following situations:
•The vehicle is on uneven su rface, such as grass,
bumps, or a hill.
•When close to other vehicl es with sonar sensors or
other objects that em it ultrasonic waves.
•There is splashing water near the sensors due to

Fuel Information
■Fuel recommendation
Use of a lower octane gasoline can cause oc casional metallic knocking noise in the
engine and will result in decreased engine performance.
Use of a gasoline with a pump octane less than 87 can lead to engine damage.
■Top tier detergent gasoline
Because the level of detergency and additi ves 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 de tergent additives and be free of metallic
additives. The proper level of detergent additives, and absence of harmful metallic
additives in gasoline, help avoid buildup of deposits in your engine and emission
control system.
For further important fuel-related informati on 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 informati on on gasoline. For more
information on top tier gasoline, visit www.toptiergas.com.
■Fuel tank capacity: 17.1 US gal (64.7 L)
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 ga soline containing methanol.
If you notice any undesira ble operating symptoms, try
another service station or sw itch to another brand of
gasoline.
