Brake 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 Brake

1

Foot 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, 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 dealer. 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 vibration 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 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.

Braking

u

Anti-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 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. Depress the brake 
pedal and 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.

ABS may activate when you depress the brake pedal when driving on:

•

Wet or snow covered roads.

•

Roads paved with stone.

•

Roads with uneven surfaces, such as potholes, cracks, manholes, etc.

When the vehicle speed goes under 6 mph (10 km/h), the ABS stops.

■

ABS

1

Anti-lock Brake System (ABS)

NOTICE

The ABS may not function correctly if you use a tire of 
the wrong 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 will 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 lockup which can lead to 
skidding and loss of steering control.

In the following cases, your 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.

Brake Assist System

Driving

Brake Assist System

Designed 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.

When Stopped

In extremely cold temperatures, the parking brake 
may freeze up if applied. If such temperatures are 
expected, do not apply the parking brake but, if 
parking on a slope, either turn the front wheels so 
they will contact the curb if the vehicle rolls down the 
slope or block the wheels to keep the vehicle from 
moving. If you do not take either precaution, the 
vehicle may roll unexpectedly, leading to a crash.

Cross Traffic Monitor

*

Cross traffic monitor may not detect or may delay 
alerting an approaching vehicle, or may alert without 
an approaching vehicle under the following 
conditions:

•

An obstacle, such as another vehicle and a wall, 
near your vehicle’s rear bumper, is blocking the 
radar sensor’s scope.

•

Your vehicle is moving at the speed of about 3 mph 
(5 km/h) or higher.

•

A vehicle is approaching at the speed other than 
between about 6 mph (10 km/h) and 16 mph (25 
km/h).

•

The system picks up external interference such as 
other radar sensors from another vehicle or strong 
radio wave transmitted from a facility nearby.

•

Either corner of the rear bumper is covered with 
snow, ice, mud or dirt.

•

When there is bad weather.

•

Your vehicle is on an incline.

•

Your vehicle is tilted due to a heavy load in the rear.

•

Your vehicle is reversing towards a wall, a pole, a 
vehicle, and so on.

The rear bumper or the sensors have been improperly 
repaired or the rear bumper has been deformed. 
Have your vehicle checked by a dealer.

For proper operation, always keep the rear bumper 
corner area clean.
Do not cover the rear bumper corner area with labels 
or stickers of any kind.

Fuel Information

■

Fuel recommendation

Use of a lower octane gasoline can cause occasional 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 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.

Fuel Information

NOTICE

We 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.

How to Refuel

Driving

How to Refuel

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.

Push on the fuel fill door release handle at 
the foot of the driver’s seat.

u

The fuel fill door opens.

4.

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.

5.

Place the fuel fill cap in the holder.

6.

Insert the fuel filler nozzle fully.

u

When the tank is full, the filler nozzle will 
click off automatically. This leaves space 
in the fuel tank in case the fuel expands 
with a change in the temperature.

u

If you do not fill up the tank to full, 
always add a minimum of 

1.3 US gal 

(5.0 L)

 of fuel.

1

How to Refuel

If the filler 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 filler nozzle has 
automatically stopped. Additional fuel can exceed 
the full tank capacity.

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 you repeatedly fill the tank with less than the 
specified minimum amount of fuel, the malfunction 
indicator lamp may come on. If this happens, have 
your vehicle checked by a dealer.
