4. Remove the fuel fill cap slowly. Youmay hear a hissing sound as
pressure inside the tank equalizes.
Place the cap in the holder on the
fuel fill door.
5. 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.
6. Screw the fuel fill cap back on until it 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 593).
7. Push the fuel fill door closed until it latches.
Tighten Fuel Cap MessageYour 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 593. Opening and Closing the Hood
1. Park the vehicle, and set the
parking brake. Pull the hood
release handle located under the
lower left corner of the dashboard.
The hood will pop up slightly.
2. Put your fingers under the frontedge of the hood near the center.
Slide your hand to your left until
you feel the hood latch handle.
Push this handle up until it
releases the hood. Lift up the
hood.
If the hood latch handle moves stiffly,
or if you can open the hood without
lifting the handle, the mechanism
should be cleaned and lubricated.

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. You will also see a
‘‘ TIGHTEN FUEL CAP ’’message on
the multi-information display.
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 90).
Readiness CodeYour 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
(set ON mode on models with keyless
access system), 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 619).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.
