uuBraking uBrake System
492
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 th e 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 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 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,  and helps you retain steering control by 
pumping the brakes rapidly, much faster than you.
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 pu mp 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 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 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 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 lockup 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 sou nds are normal to ABS 
systems and are no cause for concern.

12. Run the engine for a few minutes, and 
then check that ther e is no leak from the 
drain bolt or oil filter.
13. Stop the engine, wait for three minutes, 
and then check the  oil level on the 
dipstick.
u If necessary, add more engine oil.1Changing the Engine Oil and Oil Filter
You will need a special wrench to replace the oil 
filter. You can buy this wrench from a dealer.
When installing the new oil filter, follow the 
instructions supplied with the oil filter.
Reinstall the engine oil fill  cap. Start the engine. The 
low oil pressure indicator should go off within five 
seconds. If it does not, turn off the engine, and check 
your work.

uuMaintenance Under the Hood uEngine Coolant
Continued
Maintenance
Engine Coolant
This coolant is premixed with 50% an tifreeze and 50% water. Do not add any 
straight antifreeze or water.
We recommend you check the engine coolant  level every time you refuel. Check the 
reserve tank first. If it is completely  empty, also check the coolant level in the 
radiator. Add the engine coolant accordingly.
1. Make sure the engine and radiator are cool.
2. Check the amount of coolant in the reserve 
tank.
u If the coolant level is below the  MIN 
mark, add the specified coolant until it 
reaches the  MAX mark.
3. Inspect the cooling system for leaks.
Specified coolant: Ac ura Long Life Antifreeze/Coolant Type 2
■Reserve Tank
1Engine Coolant
NOTICE
Genuine Acura engine cool ant is a 50/50 mixture of 
antifreeze and water that can withstand freezing at 
temperatures as low as a bout -31°F (-35°C). If your 
vehicle is consistently subjected to temperatures 
below this, the concentration of antifreeze in the 
coolant should be increased. Consult a dealer for 
details.
If Acura antifreeze/coolant  is not available, you may 
use another major brand of  non-silicate coolant as a 
temporary replacement. Check  that it is a high quality 
coolant recommended for  aluminum engines. 
Continued use of any non-Ac ura coolant can result in 
corrosion, causing the coo ling system to malfunction 
or fail. Have the cooling  system flushed and refilled 
with Acura antifreeze/cool ant as soon as possible.
Do not add rust inhibitors or other additives to your 
vehicle’s cooling system. Th ey may not be compatible 
with the coolant or with the engine components.
3WARNING
Removing the radiator cap while the 
engine is hot can cause the coolant to spray 
out, seriously scalding you.
Always let the engine and radiator cool 
down before removing  the radiator cap.

Brake Fluid
The fluid level should be between the  MIN 
and  MAX  marks on the side of the reserve 
tank.
Refilling Window  Washer Fluid
Check the amount of window washer fluid by 
looking at the reservoir.
If the level is low, fill the washer reservoir.
If the washer fluid is  low, a message appears 
on the multi-information display.
Pour the washer fluid carefully. Do not 
overflow the reservoir.
Specified fluid: Acura He avy Duty Brake Fluid DOT 3
■Checking the Brake Fluid
1Brake Fluid
NOTICE
Brake fluid marked DOT 5 is not compatible with your 
vehicle's braking system  and can cause extensive 
damage.
If the specified br ake fluid is not av ailable, you should 
use only DOT 3 or DOT 4 fluid from a sealed 
container as a temporary replacement.
Using any non-Acura brake fl uid can cause corrosion 
and decrease the longevity of the system. Have the 
brake system flushed and re filled with Acura Heavy 
Duty Brake Fluid DOT 3 as soon as possible.
If the brake fluid level is at or below the  MIN mark, 
have a dealer inspect the vehicle for leaks or worn 
brake pads as soon as possible.
