This shows the temperature of the
engine’s coolant. During normal
operation, the pointer should rise to
about the middle of the gauge. In
severe driving conditions, the pointer
may rise to the upper zone. If it
reaches the red (Hot) mark, pull
safely to the side of the road. Turn to
page f or instructions and
precautions on checking the engine’s
cooling system.
This shows how much f uel you have.
It may show slightly more or less
than the actual amount. The needle

U.S. Vehicles:
According to state and federal
regulations, f ailure to perf orm
maintenance on the items marked
with will not void your emissions
warranties. However, Acura
recommends that all maintenance
services be perf ormed in accordance
with the intervals indicated by the
Multi-Inf ormation Display.
Youshouldcheckthefollowing
items at the specif ied intervals. If
you are unsure of how to perf orm
any check, turn to the appropriate
page listed.
Lights Check the operation of
the headlights, parking lights,
taillights, high-mount brake light,
and license plate lights monthly.
See page .
Engine coolant level Check the
radiator reserve tank every time
you f ill the f uel tank. See page . Engine oil level Check every
time you fill the fuel tank. See

Independent of the maintenance messages in the Multi-Information
Display, replace the brake fluid every 3 years.
If the message ‘‘SERVICE DUE NOW’’ does not appear more than 12 months
after the display is reset, change the engine oil every year.
See information on maintenance and emissions warranty, the first column,
page .
Inspect idle speed every 160,000 miles (256,000 km).
Adjust the valves during services A, B, 1, 2, or 3 if they are noisy.

Inspect front and rear brakes
Check parking brake adjustment
Visually inspect these items: Tie rod ends, steering gear box, and boots
Suspension components
Driveshaft boots
Brake hoses and line (including ABS)
All fluid levels and condition of fluids
Exhaust system
Fuel lines and connections Maintenance Sub Items
Rotate tires
Replace air cleaner element If you drive primarily in dusty conditions, replace
every 15,000 miles (24,000 km).
Replace dust and pollen filter If you drive primarily in urban areas that have high
concentrations of soot in the air from industry and
from diesel-powered vehicles, replace every 15,000
miles (24,000 km).
Inspect drive belt
Replace transmission fluid Driving in mountainous areas at very low vehicle
speeds results in higher transmission temperatures.
This requires transmission fluid changes more
frequently than recommended by the Maintenance
Minder. If you regulary 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).
Replace spark plugs
Replace timing belt and inspect water pump If you drive regularly in very high temperatures (over
110°F, 43°C), or in very low temperatures (under-20°F,
29°C), replace every 60,000 mile (U.S.)/100,000 km

If 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 f or leaks.
Always use Honda All Season
Antif reeze/Coolant Type 2. This
coolant is pre-mixed with 50 percent
antif reeze and 50 percent water.
Never add straight antifreeze or
plain water.If Honda antif reeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporaryreplacement.Makesureit
is a high-quality coolant
recommended f or aluminum engines.
Continued use of any non-Honda
coolant can result in corrosion,
causing the cooling system to
malf unction or f ail. Have the cooling
system f lushed and ref illed with
Honda antif reeze/coolant as soon as
possible.
If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.

RESERVE TANK
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.

When the radiator and engine are
cool, relieve any pressure in the
cooling system by turning the
radiator cap counterclockwise,
without pressing down.
Remove the radiator cap by
pushing down and turning
counterclockwise.The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
Pourthecoolantslowlyand
caref ully so you do not spill. Clean
up any spill immediately; it could
damage components in the engine
compartment.
Put the radiator cap back on and
tighten it.
Pour coolant into the reserve tank.
Fill it to half way 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. Check the f luid level in the
windshield washer reservoir at least
monthly during normal use.
If the f luid level
is low, a message will be shown on
the Multi-Information Display.
Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather.
When you ref ill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer f luid
on a clean cloth. This will help to
condition them.

NOTICE:
RADIATOR CAP
Do not use engine antif reeze
or a vinegar/water solution in the
windshield washer reservoir. Antif reeze
can damage your vehicle’s paint, while
a vinegar/water solution can damage
the windshield washer pump. Use only
commercially-available windshield
washer f luid.

If you do not see steam or spray,
leave the engine running, and
watch the temperature gauge. If
the high heat is due to overloading,
the engine should start to cool
down almost immediately. If it
does, wait until the temperature
gauge comes down to the midpoint,
then continue driving.
Saf ely pull to the side of the road.
Put the transmission in Neutral or
Park, and set the parking brake.
Turn of f all accessories, and turn
on the hazard warning indicators.
If you see steam and/or spray
coming f rom under the hood, turn
of f the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
The pointer of the vehicle’s
temperature gauge should stay in
the midrange. If it climbs to the red
mark, you should determine the
reason (hot day, driving up a steep
hill, etc.).
If the vehicle overheats, you should
take immediate action. The only
indication may be the temperature
gauge climbing to or above the red
mark. Or you may see steam or
spray coming f rom under the hood.
If the temperature gauge stays at
the red mark, turn of f the engine.
Look f or any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you f ind a leak, it
must be repaired bef ore you
continue driving (see
on page ).
