Screw the fuel fill cap back on
until it clicks at least three times.
If you do not properly tighten the
cap, the Malf unction Indicator

Push the f uel f ill door closed until
it latches.
Park the vehicle, and set the
parking brake. Pull the hood
release handle located under the
lower lef t corner of the dashboard.
The hood will pop up slightly.Put your f ingers under the f ront

Look at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, seeon page f or
inf ormation on adding the proper
coolant. Always maintain your vehicle
according to the maintenance
schedule. See
(see page
). Try to maintain a constant speed.
Everytimeyouslowdownand
speed up, your vehicle uses extra
fuel.Usethecruisecontrolwhen
appropriate.
Combine several short trips into
one.
The air conditioning puts an extra
load on the engine which makes it
usemorefuel.Usethefresh-air
ventilation when possible.
Refer to on page f or inf ormation
about checking other items on your
Acura. The build-up of snow or mud on
your vehicle’s underside adds
weight and rolling resistance.
Frequent cleaning helps your f uel
mileage and reduces the chance of
corrosion.
Drive moderately. Rapid
acceleration, abrupt cornering and
hard braking use more f uel.
Always drive in the highest gear
possible.an underinf lated tire
causes more ‘‘rolling resistance,’’
which uses f uel.

Maintenance Schedule for Severe Conditions

To saf ely operate your vehicle, your
tires must be the proper type and
size, in good condition with adequate
tread, and correctly inf lated.
The f ollowing pages give more
detailed inf ormation on how to take
care of your tires and what to do
when they need to be replaced.Keeping the tires properly inf lated
provides the best combination of
handling, tread lif e, and riding
comf ort.
Underinf lated tires wear unevenly,
adversely affect handling and fuel
economy, and are more likely to f ail
f rom being overheated.
Overinf lated tires can make your
vehicleridemoreharshly,aremore
prone to damage from road hazards,
and wear unevenly.Use a gauge to measure the air
pressure at least once a month. Even
tires that are in good condition may
lose one to two psi (10 to 20 kPa, 0.1
to 0.2 kgf /cm ) per month.
Remember to check the spare tire at
thesametime.
Add or release air, if needed, to
match the recommended cold tire
pressures on page .
The Tire Pressure Monitoring
System (TPMS) will warn you when
a tire pressure is low. See page
f or inf ormation on the TPMS.
We recommend that you visually
check your tires every day. If you
think a tire might be low, check it
immediately with a tire gauge. Check the pressure in the tires when
they are cold. This means the vehicle
has been parked f or at least three
hours, or driven less than 1 mile (1.6
km).

Using tires that are excessively
worn or improperly inflated can
cause a crash in which you can
be seriously hurt or killed.

The exhaust emissions controls
include f our 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
comes out the tailpipe. The exhaust
emissions control systems are
separate f rom the crankcase and
evaporative emissions control
systems.
The PGM-FI System uses sequential
multiport f uel 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 f uel to inject under all
operating conditions.This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The Exhaust Gas Recirculation
(EGR) system takes some of the
exhaust gas and routes it back into
the intake manif old. Adding exhaust
gas to the air/f uel mixture reduces
the amount of NOx produced when
the f uel is burned.
The 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 ), dinitrogen
(N ), and water vapor.
The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual f or more informa-
tion. The emissions control systems are
designed and certif ied 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 f or repairs. Using lower
qualitypartsmayincreasethe
emissions f rom your vehicle.
