Adding Engine CoolantIf the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to the MAX
line. Inspect the cooling system for
leaks.Always use Honda Long-life Anti-
freeze/Coolant Type 2. This coolant
is pre-mixed with 50 percent
antifreeze and 50 percent water.
Never add straight antifreeze or plain
water.
If Honda antifreeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporary replacement. Make sure 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.If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
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.

1. Make sure the engine and radiatorare cool.
2. Relieve any pressure in the cooling system by turning the radiator cap
counterclockwise, without
pressing down.
3. Remove the radiator cap bypushing down and turning
counterclockwise. 4. The coolant level should be up to
the base of the filler neck. Add
coolant if it is low.
Pour the coolant slowly and
carefully so you do not spill any.
Clean up any spill immediately; it
could damage components in the
engine compartment.
5. Put the radiator cap back on, and tighten it fully.

6. Pour coolant into the reserve tank.Fill it to halfway between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Do not add any rust inhibitors or
other additives to your vehicle's
cooling system. They may not be
compatible with the coolant or
engine components. Windshield Washers
Check and fill the windshield washer
reservoir according to the warning
message on the multi-information
display.
If the washer fluid is low, a
‘‘LOW
WASHER FLUID ’’message appears
on the multi-information display.
Fill the reservoir with a good-quality
windshield washer fluid. This
increases the cleaning capability and
prevents freezing in cold weather.
When you refill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer fluid
on a clean cloth. This will help to
condition the blade edges.
Do not use engine antifreeze or a
vinegar/water solution in the
windshield washer reservoir. Antifreeze
can damage your vehicle's paint, while
a vinegar/water solution can damage
the windshield washer pump. Use only
commercially-available windshield
washer fluid.

Check the fluid level with the engine
at normal operating temperature.1. Park the vehicle on level ground. Start the engine, let it run until the
radiator fan comes on, then shut
off the engine. For accurate
results, wait about 60 seconds (but
no longer than 90 seconds) before
doing step 2.
2. Remove the dipstick (yellow loop)from the transmission, and wipe it
with a clean cloth.
3. Insert the dipstick all the way intothe transmission securely as
shown in the illustration.
4. Remove the dipstick and check the fluid level. It should be between
the upper and lower marks.

5. If the level is below the lowermark, add fluid into the dipstick
hole to bring it to the level
between the upper and lower
marks.
Pour the fluid slowly and carefully
so you do not spill any. Clean up
any spill immediately; it could
damage components in the engine
compartment.
Always use Acura ATF-Z1
(automatic transmission fluid.)
6. Insert the dipstick all the way back into the transmission securely as
shown in the illustration.
Make sure the rubber cap on the
dipstick fits in the dipstick guide
and that you push the dipstick in
all the way. The transmission should be drained
and refilled with new fluid when this
service is shown on a maintenance
message in the multi-information
display.
If you are not sure how to add fluid,
contact your dealer.
Use only Acura ATF-Z1 (automatic
transmission fluid). Do not mix with
other transmission fluids.
Using transmission fluid other than
Acura ATF-Z1 may cause deterioration
in transmission operation and
durability, and could result in damage
to the transmission.
Damage resulting from the use of
transmission fluid other than Acura
ATF-Z1 is not covered by the Acura
new vehicle warranty.

Check the fluid level in the brake
fluid reservoir monthly.
You will also see the‘‘LOW BRAKE
FLUID ’’message on the multi-
information display when the brake
fluid level is low.
Independent of the maintenance
minder display, replace the brake
fluid every 3 years. Always use Honda Heavy Duty
Brake Fluid DOT 3. If it is not
available, you should use only DOT 3
or DOT 4 fluid, from a sealed
container, as a temporary
replacement.
Using any non-Honda brake fluid can
cause corrosion and decrease the life
of the system. Have the brake
system flushed and refilled with
Honda Heavy Duty Brake Fluid DOT
3 as soon as possible.
Brake fluid marked DOT 5 is not
compatible with your vehicle's
braking system and can cause
extensive damage.
The fluid level should be between
the MIN and MAX marks on the side
of the reservoir. If the level is at or
below the MIN mark, your brake
system needs attention. Have the
brake system inspected for leaks or
worn brake pads.

Power Steering FluidCheck the level on the side of the
reservoir when the engine is cold.
The fluid should be between the
UPPER LEVEL and LOWER LEVEL.
If not add power steering fluid to the
UPPER LEVEL mark.
Pour the fluid slowly and carefully so
you do not spill any. Clean up any
spills immediately; it could damage
components in the engine
compartment.Always use Acura Power Steering
Fluid. You may use another power
steering fluid as an emergency
replacement, but have the power
steering system flushed and refilled
with Acura PSF as soon as possible.
A low power steering fluid level can
indicate a leak in the system. Check
the fluid level frequently, and have
the system inspected as soon as
possible.
If you are not sure how to add fluid,
contact your dealer.
Turning the steering wheel to full left or
right lock and holding it there can
damage the power steering pump.
Timing Belt
The timing belt should be replaced at
the intervals shown in the
maintenance minder schedule.
Replace the timing belt every 60,000
miles (U.S.) or every 100,000 km
(Canada) if you regularly drive your
vehicle in any of the following
conditions:
●In very high temperatures
(over 110°F, 43°C).●In very low temperatures
(under
-20°F, -29°C).●Frequently tow a trailer.

Headlight Aiming
The headlights were properly aimed
when your vehicle was new. If you
regularly carry heavy items in the
cargo area or pull a trailer,
readjustment may be required.
Adjustments should be done by your
dealer or another qualified
technician.
Low/High Beam Headlight Bulb
Replacement
The low/high beam headlight bulbs
are a type of high voltage discharge
tube. High voltage can remain in the
circuit even with the light switch off
and the key removed (or the vehicle
is in VEHICLE OFF (LOCK) mode
on models with keyless access
system). Because of this, you should
not attempt to examine or change a
low/high beam headlight bulb
yourself. If a low/high beam
headlight bulb fails, take the vehicle
to your dealer to have it replaced.Replacing Front Turn Signal/
Parking and Side Marker Light
Bulbs
1. Open the hood.
2. Remove the front bulkhead cover
and engine compartment covers
(see page 544).
3. Remove the socket by turning it one-quarter turn counterclockwise.
4. Pull the bulb straight out of its socket.
5. Push the new bulb straight intothe socket until it bottoms.
6. Insert the socket back into the headlight assembly. Turn it
clockwise to lock it in place.
7. Turn on the lights to make sure the new bulb is working.
