uuBrakinguBrake System
238Driving
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.2Brake Assist System P. 240
2ABS (Anti-lock Brake System) P. 239■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.

uuMaintenance Under the HooduOil Check
Maintenance
Oil CheckWe recommend that you check the engine oil level every time you refuel.
Park the vehicle on level ground.
Wait approximately three minutes after turning the engine off before you check the
oil.
1.Remove the dipstick (orange handle).
2.Wipe the dipstick with a clean cloth or
paper towel.
3.Insert the dipstick back all the way into its
hole.
1Oil Check
If the oil level is near or below the lower mark, slowly
add oil being careful not to overfill.

3.Reinstall the engine oil fill cap, and tighten
it securely.
4.Wait for three minutes and recheck the
engine oil dipstick.
1Adding Engine Oil
If any oil spills, wipe it up immediately. Spilled oil may
damage the engine compartment components.NOTICEDo not fill the engine oil above the upper mark.
Overfilling the engine oil can result in leaks and
engine damage.

5.Remove the oil filter and dispose of the
remaining oil.
6.Check that the filter gasket is not stuck to
the engine contact surface.
uIf it is stuck, you must detach it.
7.Wipe away dirt and dust adhering to the
contact surface of the engine block, and
install a new oil filter.
uApply a light coat of new engine oil to
the oil filter rubber seal.
8.Put a new washer on the drain bolt, then
reinstall the drain bolt.

11.Run the engine for a few minutes, and
then check that there is no leak from the
drain bolt or oil filter.
12.Stop the engine, wait for three minutes,
and then check the oil level on the dipstick.
uIf 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 HooduEngine Coolant
Maintenance
Engine CoolantThis coolant is premixed with 50% antifreeze 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.Check the amount of coolant in the reserve
tank.
2.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: Honda Long Life Antifreeze/Coolant Type 2■Reserve Tank
1Engine CoolantNOTICEIf temperatures consistently below -22°F (-30°C) are
expected, the coolant mixture should be changed to
a higher concentration. Consult a dealer for more
information.
If Honda antifreeze/coolant is not available, you may
use another major brand non-silicate coolant as a
temporary replacement. Check that it is a high quality
coolant recommended for aluminum engines.
Continued use of any non-Honda coolant can result
in corrosion, causing the cooling system to
malfunction or fail. Have the cooling system flushed
and refilled with Honda antifreeze/coolant as soon as
possible.
Do not add rust inhibitors or other additives to your
vehicle's coolant system. They may not be compatible
with the coolant or with the engine components.

uuMaintenance Under the HooduTransmission Fluid
Maintenance
Transmission FluidCheck the fluid level when the engine is at normal operating temperature.
1.Park on level ground, and start the engine.
2.Wait until the radiator fan starts and then
turn off the engine.
uPerform step 3 after waiting for about 60
seconds (less than 90 seconds).
3.Remove the dipstick (yellow loop) from the
transmission and wipe it with a clean cloth.
4.Insert the dipstick all the way back into the
transmission securely, as shown in the
image.
5.Remove the dipstick and check the fluid
level.
uIt should be between the upper and
lower marks in the HOT range.
6.If the level is below the lower mark, add
fluid into the dipstick hole to bring it to the
level between the upper and lower marks,
and have your vehicle checked by a dealer
immediately.■Automatic Transmission FluidSpecified fluid: Acura ATF DW-1 (automatic transmission fluid)
1Automatic Transmission FluidNOTICEDo not mix Acura ATF DW-1 with other
transmission fluids.
Using a transmission fluid other than Acura ATF
DW-1 may adversely affect the operation and
durability of your vehicle's transmission, and damage
the transmission.
Any damage caused by using a transmission fluid that
is not equivalent to Acura ATF DW-1 is not covered
by Acura's new vehicle warranty.NOTICEPour the fluid slowly and carefully so you do not spill
any. Clean up any spills immediately; they can
damage components in the engine compartment.
