Refueling1. Park with the driver's side closestto the service station pump.
2. Open the fuel fill door by pressing the button in the driver's door. (To
open the fuel fill door manually,
see page 566.)
3. Remove the fuel fill cap slowly.You may hear a hissing sound as
pressure inside the tank equalizes.
Place the cap in the holder on the
fuel fill door.
4. Stop filling the tank after the fuel nozzle automatically clicks off. Do
not try to ‘‘top off ’’the tank. Leave
some room for the fuel to expand
with temperature changes. If the fuel nozzle keeps clicking off
even though the tank is not full,
there may be a problem with your
vehicle's fuel vapor recovery system.
The system helps keep fuel vapor
from going into the atmosphere. Try
filling at another pump. If this does
not fix the problem, consult your
dealer.
Gasoline is highly flammable
and explosive. You can be
burned or seriously injured
when handling fuel.●
Stop the engine, and keep
heat, sparks, and flame
away.
●
Handle fuel only outdoors.
●
Wipe up spills immediately.

5. Screw the fuel fill cap back on untilit clicks at least once. If you do not
properly tighten the cap, you will
see a ‘‘TIGHTEN FUEL CAP ’’
message on the multi-information
display (see right column on this
page), and the malfunction
indicator lamp may also come on
(see page 557).
6. Push the fuel fill door closed until it latches. Tighten Fuel Cap Message
Your vehicle's on board diagnostic system
will detect a loose or missing fuel fill cap as
an evaporative system leak. The first time a
leak is detected a
‘‘TIGHTEN FUEL CAP’’
message appears on the multi-information
display. Turn the engine off, and confirm the
fuel fill cap is installed. If it is, loosen it, then
retighten it until it clicks at least once. The
message should go off after several days of
normal driving once you tighten or replace
the fuel fill cap. To scroll to another message,
press the INFO button. The ‘‘TIGHTEN
FUEL CAP’’ message will appear each time
you restart the engine until the system turns
the message off.
If the system still detects a leak in
the vehicle's evaporative emissions
system, the malfunction indicator
lamp (MIL) comes on. If the fuel fill
cap was not already tightened, turn
the engine off, and check or
retighten the fuel fill cap until it
clicks at least once. The MIL should
go off after several days of normal
driving once the cap is tightened or
replaced. If the MIL does not go off,
have your vehicle inspected by a
dealer. For more information, see
page 557.

Unscrew and remove the engine oil
fill cap on top of the valve cover. Pour
in the oil slowly and carefully so you
do not spill. Clean up any spills
immediately. Spilled oil could
damage components in the engine
compartment.
Reinstall the engine oil fill cap, and
tighten it securely. Wait a few
minutes, and recheck the oil level on
the engine oil dipstick. Do not fill
above the upper mark; you could
damage the engine.Recommended Engine Oil
Oil is a major contributor to your
engine's performance and longevity.
Always use a premium-grade 5W-20
detergent oil displaying the API
Certification Seal. This seal indicates
the oil is energy conserving, and that
it meets the American Petroleum
Institute's latest requirements. It is
highly recommended that you use
Acura motor oil in your vehicle.
Make sure the API Certification Seal
says
‘‘For Gasoline Engines. ’’
The oil viscosity or weight is
provided on the container's label.
5W-20 oil is formulated for year-
round protection of your vehicle to
improve cold weather starting and
fuel economy.

If this indicator comes on
while driving, it means one
of the engine's emissions control
systems may have a problem. Even
though you may feel no difference in
your vehicle's performance, it can
reduce your fuel economy and cause
increased emissions. Continued
operation may cause serious damage.
If you have recently refueled your
vehicle, the indicator coming on
could be due to a loose or missing
fuel fill cap. Tighten the cap until it
clicks at least once. Tightening the
cap will not turn the indicator off
immediately; it can take several days
of normal driving. If the indicator comes on repeatedly,
even though it may turn off as you
continue driving, have your vehicle
checked by the dealer as soon as
possible.
If you keep driving with the malfunction
indicator lamp on, you can damage
your vehicle's emissions controls and
engine. Those repairs may not be
covered by your vehicle's warranties.
You will also see a
‘‘CHECK
EMISSION SYSTEM ’’message on
the multi-information display (see
page 86).
Readiness Code
Your vehicle has certain ‘‘readiness
codes ’’that are part of the on-board
diagnostics for the emissions systems. In
some states, part of the emissions testing
is to make sure these codes are set. If
they are not set, the test cannot be
completed.
If the battery in your vehicle has been
disconnected or gone dead, these codes
may be erased. It takes several days of
driving under various conditions to set
the codes again.
To check if they are set, turn the ignition
switch to the ON (II) position, without
starting the engine. The malfunction
indicator lamp will come on for 20
seconds. If it then goes off, the readiness
codes are set. If it blinks five times, the
readiness codes are not set. If possible,
do not take your vehicle for an emissions
test until the readiness codes are set.
Refer to Emissions Testing for more
information (see page 583).Malfunction Indicator Lamp

Onboard Refueling Vapor
Recovery
The onboard refueling vapor
recovery (ORVR) system captures
the fuel vapors during refueling. The
vapors are adsorbed in a canister
filled with activated carbon. While
driving, the fuel vapors are drawn
into the engine and burned off.
Exhaust Emissions Controls
The exhaust emissions controls
include four systems: PGM-FI,
ignition timing control, exhaust gas
recirculation, and three way catalytic
converter. These four systems work
together to control the engine's
combustion and minimize the
amount of HC, CO, and NOx that
come out the tailpipe. The exhaust
emissions control systems are
separate from the crankcase and
evaporative emissions control
systems.
PGM-FI SystemThe PGM-FI system uses sequential
multiport fuel injection. It has three
subsystems: air intake, engine
control, and fuel control. The
powertrain control module (PCM)
uses various sensors to determine
how much air is going into the
engine. It then controls how much
fuel to inject under all operating
conditions.Ignition Timing Control SystemThis system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.Exhaust Gas Recirculation (EGR)SystemThe exhaust gas recirculation (EGR)
system takes some of the exhaust
gas and routes it back into the intake
manifold. Adding exhaust gas to the
air/fuel mixture reduces the amount
of NOx produced when the fuel is
burned.
Three Way Catalytic ConverterThe three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine's exhaust
to carbon dioxide (CO
2), nitrogen
(N
2), and water vapor.
Replacement Parts
The emissions control systems are
designed and certified to work
together in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Acura replacement parts or their
equivalent for repairs. Using lower
quality parts may increase the
emissions from your vehicle.
The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for more
information.
