U.S. Vehicles:Maintenance,
replacement, or repair of
emissions control devices and
systems may be done by any
automotive repair establishment
or individual using parts that are
‘‘ certified ’’to EPA standards.
According to state and federal
regulations, failure to perform
maintenance on the items marked
with ＃will not void your emissions
warranties. However, Acura
recommends that all maintenance
services be performed in accordance
with the intervals indicated by the
multi-information display. Owner's Maintenance Checks
You should check the following
items at the specified intervals. If you
are unsure of how to perform any
check, turn to the appropriate page
listed.
●Engine oil level
－Check every
time you fill the fuel tank. See page
356.●Engine coolant level －Check the
radiator reserve tank every time
you fill the fuel tank. See page 357.●Automatic transmission－Check
the fluid level monthly. See page
427.
●Brakes －Check the fluid level
monthly. See page 429.●Tires－Check the tire pressure
monthly. Examine the tread for
wear and foreign objects. See page
445.●Lights －Check the operation of

Diagnosing why the engine won't
start falls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position:●You hear nothing, or almost
nothing. The engine's starter
motor does not operate at all, or
operates very slowly.●You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
faster than normal, but the engine
does not start up and run.Nothing Happens or the Starter
Motor Operates Very Slowly
When you turn the ignition switch to
the START (III) position, you do not
hear the normal noise of the engine
trying to start. You may hear a
clicking sound, a series of clicks, or
nothing at all.
Check these things:
●Check the transmission interlock.
The transmission must be in Park
or neutral or the starter will not
operate.●Turn the ignition switch to the ON
(II) position. Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See
Jump Starting
on page461.
●Turn the ignition switch to the
START (III) position. If the
headlights do not dim, check the
condition of the fuses. If the fuses
are OK, there is probably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualified mechanic to
determine the problem (see
Emergency Towing on page475).
If the headlights dim noticeably or go
out when you try to start the engine,
either the battery is discharged or
the connections are corroded. Check
the condition of the battery and
terminal connections (see page 450).
You can then try jump starting the
vehicle from a booster battery (see
page 461).

Low Oil Pressure Indicator
This indicator should never
come on when the engine is
running. If it starts flashing or stays
on, the oil pressure has dropped very
low or lost pressure. Serious engine
damage is possible, and you should
take immediate action.
You will also see an ‘‘OIL PRESSURE
LOW ’’message on the multi-
information display (see page 79).
Running the engine with low oil
pressure can cause serious mechanical
damage almost immediately. Turn off
the engine as soon as you can safely get
the vehicle stopped. 1. Safely pull off the road, and shut
off the engine. Turn on the hazard
warning lights.
2. Let the vehicle sit for a minute. Open the hood, and check the oil
level (see page 356). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers.
3. If necessary, add oil to bring the level back to the full mark on the
dipstick (see page 420).
4. Start the engine, and watch the oil pressure indicator. If it does not go
out within 10 seconds, turn off the
engine. There is a mechanical
problem that needs to be repaired
before you can continue driving
(see Emergency Towing on page
475). Charging System Indicator
If the charging system
indicator comes on brightly
when the engine is running, the
battery is not being charged.
You will also see a ‘‘CHECK
CHARGING SYSTEM ’’message on
the multi-information display (see
page 79).
Immediately turn off all electrical
accessories. Try not to use other
electrically operated controls such as
the power windows. Keep the engine
running; starting the engine will
discharge the battery rapidly.
Go to a service station or garage
where you can get technical
assistance.
