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.

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.

*4: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher transmission
temperatures. This requires transmission fluid changes more frequently than recommended by the
Maintenance Minder. If you regularly drive your vehicle under these conditions, have the transmission
fluid changed at 60,000 miles (100,000 km), then every 30,000 miles (48,000 km). (For A/T only.)
*5: If you drive regularly in very high temperatures (over 110°F, 43 °C), in very low temperatures (under
-20°F, -29°C), or tow a trailer, replace every 60,000 miles/100,000 km. (6-cylinder models only)

uuChecking and Maintaining TiresuTire and Wheel Replacement
Maintenance
Tire and Wheel ReplacementReplace 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.
Make sure that the wheel’s specifications match those of the original wheels.
If you replace a wheel, only use TPMS specified wheels approved for your vehicle.

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.

Handling the Unexpected
If the Brake System Indicator Comes On
■
Reasons for the indicator to come on
•The brake fluid is low.
•There is a malfunction in the brake system.
■
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.
•If abnormal, take immediate action. If necessary, downshift the
transmission to slow the vehicle using engine braking.
If the EPS Indicator Comes On
■
Reasons for the indicator to come on
•Comes on when there is a problem with EPS.
•If you depress the accelerator pedal repeatedly to increase the 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.
1If 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.

1If the EPS Indicator Comes On
NOTICEIf 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.
