2004 HONDA ODYSSEY engine

This indicator should never
come on when the engine is
running. If it starts f lashing or stays
on, the oil pressure has dropped very
low or lost pressure. Serious engine
damage is possible and you should
take immediate action. Saf ely pull of f the road, and shut
of f the engine. Turn on the hazard
warning indicators.
Let the vehicle sit f or a minute.
Open the hood, and check the oil
level (see page ). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers.
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ).
Start the engine, and watch the oil
pressure indicator. If it does not go
out within 10 seconds, turn of f the
engine. There is a mechanical
problem that needs to be repaired
bef ore you can continue driving.
(See
on page
). Immediately turn of f 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 Honda dealer or a service
station where you can get technical
assistance.
If the charging system
indicator comes on brightly
when the engine is running, the
battery is not being charged.

NOTICE:
Running the engine with low
oil pressure can cause serious
mechanical damage almost immediately.
Turn of f the engine as soon as you can
saf ely get the vehicle stopped.

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 f eel no dif f erence in
your vehicle’s perf ormance,
continued operation may cause
serious damage.
If you have recently ref ueled your
vehicle, the indicator could come on
because of a loose or missing f uel f ill
cap. Tighten the cap until it clicks at
least three times. Tightening the cap
will not turn the indicator turn of f
immediately; it takes at least three
days of normal driving.
If the indicator remains on, or the
f uel cap was not loose or missing,
have your vehicle checked by the
dealer as soon as possible. This indicator may also come on
along with the ‘‘D’’ indicator.
Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or 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 your vehicle battery has been
disconnected or gone dead, these
codes are erased. It takes at least
three days of driving under various
conditions to set the codes again.To check if they are set, turn the
ignition switch to ON (II), without
starting the engine. The Malf unction
Indicator Lamp will come on f or 20
seconds. If it then goes of f , the
readiness codes are set. If it blinks 5
times, the readiness codes are not
set. If possible, do not take your
vehicle f or a state emissions test
until the readiness codes are set.
Refer to State Emissions Testing for
more information (see page ).

If your vehicle needs to be towed,
call a prof essional towing service or
organization. Never tow your vehicle
with just a rope or chain. It is very
dangerous.
There are three popular types of
prof essional towing equipment. The tow
truck uses two pivoting arms that go
under the tires (f ront or rear) and lif t
them of f the ground. The other two
tires remain on the ground. The tow
truck uses metal cables with hooks
on the ends. These hooks go around
parts of the f rame or suspension and
the cables lif t that end of the vehicle
of f the ground. Your vehicle’s sus-
pension and body can be seriously
damaged.
Release the parking brake.
Start the engine.

Turn of f the engine.
The operator
loads your vehicle on the back of a
truck. If your Honda cannot be transported
by f latbed, it should be towed by
wheel-lif t equipment with the f ront
wheels of f the ground. If , due to
damage, your vehicle must be towed
with the f ront wheels on the ground,
do the f ollowing:With the f ront wheels on the ground,
it is best to tow the vehicle no farther
than 50 miles (80 km), and keep the
speedbelow35mph(55km/h).

NOTICE: Improper towing preparation
will damage the transmission. Follow
the above procedure exactly. If you
cannot shif t the transmission or start
the engine, your vehicle must be
transported with the f ront wheels of f

Your vehicle has several identif ying
numbers in various places.
The Vehicle Identif ication Number
(VIN) is the 17-digit number your
Honda dealer uses to register your
vehicle f or warranty purposes. It is
also necessary f or licensing and
insuring your vehicle. The easiest

Youcanseeitbylookingthrough
the windshield on the driver’s side. It
is also on the Certification label at-
tached to the driver’s doorjamb, and
is stamped on the engine com-
partment bulkhead. The VIN is also
provided in bar code on the
Certif ication label.

ÎThe burning of gasoline in your
vehicle’s engine produces several by-
products. Some of these are carbon
monoxide (CO), oxides of nitrogen
(NOx) and hydrocarbons (HC).
Gasoline evaporating f rom the tank
also produces hydrocarbons. Con-
trolling the production of NOx, CO,
and HC is important to the environ-
ment. Under certain conditions of
sunlight and climate, NOx and HC
react to f orm photochemical ‘‘smog.’’
Carbon monoxide does not contri-
bute to smog creation, but it is a
poisonous gas. The United States Clean Air Act
sets standards f or automobile
emissions. It also requires that
automobile manufacturers explain to
owners how their emissions controls
workandwhattodotomaintain
them. This section summarizes how
the emissions controls work.
Scheduled maintenance is on pages
and .
In Canada, Honda vehicles comply
with the Canadian emission
requirements, as specif ied in an
agreement with Environment
Canada, at the time they are
manuf actured.
Your vehicle has a Positive
Crankcase Ventilation System. This
keeps gasses that build up in the
engine’s crankcase f rom going into
the atmosphere. The Positive Crank- case Ventilation valve routes them
from the crankcase back to the
intake manif old. They are then
drawn into the engine and burned.
As gasoline evaporates in the f uel
tank, an evaporative emissions
control canister f illed with charcoal
adsorbs the vapor. It is stored in this
canister while the engine is of f . Af ter
the engine is started and warmed up,
the vapor is drawn into the engine
and burned during driving.
The Onboard Ref ueling Vapor
Recovery (ORVR) system captures
the f uel vapors during ref ueling. The
vapors are adsorbed in a canister
f illed with activated carbon. While
driving, the f uel vapors are drawn
into the engine and burned of f .
