look at the oil level on the dipstick.
The dipstick has two markings which indicate the minimum and
maximum allowable oil level. If the
oil level is lower than the markedarea, it indicates the need for
additional oil. Push the dipstick
back down all the way after taking the reading. If you check the oil level when
the oil is cold, do not run the
engine first. The cold oil will not drain into the pan fast
enough to give a true reading.

Engin e Oi l Additive s

There are many extra engine oil additives for sale. Your engine
should not need these extra
additives if you use recommended
quality engine oil and change it as suggested. If you think your

engine has an oil-related problem,

talk to your Honda dealer. Ai
r Cleane r Filte r
See your Maintenance Schedule for
change intervals. If the vehicle is operated in dusty areas it will
require more frequent element
replacement. Your Honda dealer
can be of assistance in determining the proper replacement frequency
for the conditions under which you
operate your vehicle.
Do not attempt to clean the air
filter. The filter is designed to
provide normal filtering
efficiency between replacement intervals.
For maximum protection, it is advisable to use genuine Honda air
cleaner filters as replacements.
Car e an d Maintenanc e

Never run the engine with the air
cleaner filter removed. If the
engine should backfire, it could
possibly cause an engine
compartment fire.
Be sure to reinstall the air cleaner
filter and assembly correctly. If it is installed incorrectly, engine
damage could result. Manua
l Transmissio n Flui d
See the Maintenance Schedule to
find out how often the lubricant
level should be checked.
Check that the fluid level reaches
the plug hole by removing the
filler plug on the transmission and transfer case. If the fluid level is
low, refill the case up to the filler
plug hole.
Use a high-quality engine oil
labeled SG or SF that is of the
correct viscosity for existing ambient temperatures as follows.

See the Maintenance Schedule
List to determine how often the lubricant should be changed. Add
lubricant, if needed, by filling to
the level of the filler plug hole.
Use GL-5 gear lubricant of the
proper viscosity as shown in the

chart.

If your vehicle is equipped with
the optional limited slip
differential (on the rear axle), use GL-5 Limited Slip Differential
Gear Lubricant together with
Limited Slip Differential Gear

The engine cooling system is
designed to maintain the engine at
the proper operating temperatures.
The cooling system was filled at the factory with a quality engine
coolant. The engine cooling system is designed to use coolant (a
mixture of water and ethylene glycol antifreeze) rather than plain
water. The engine coolant solutionshould be used year-round. It has
many advantages such as: provides freezing protection as

lowas — 33°F( — 36°C)
provides boiling protection up
to262°F(128°C)
protects against rust and
corrosion in the cooling system maintains the proper engine
temperature for efficient
operation and emission control
allows proper operation of the
engine coolant temperature gaugeSee the Maintenance Schedule in
this section to find out when the
engine coolant must be replaced.

Checkin g th e Coolan t Leve l

Check the engine coolant level at the interval shown in the
Maintenance Schedule unless there
is evidence of leaking or
overheating. The engine coolant
level should be between the
maximum and the minimum level
marks on the radiator reserve tank.

You usually do not need to remove
the radiator cap to check the engine
coolant level.
Addin g Engin e Coolan t
To add engine coolant, remove the cap on the radiator reserve tank
and fill the tank up to the
maximum level mark. Add a
50/50 mixture of water and a good
quality ethylene glycol antifreeze. If you need to add engine coolant
frequently, see your Honda dealer
for a cooling system check.
If the proper quality antifreezeis used, there is no need to add
extra inhibitors or additives. They may be harmful to the proper
operation of the system.
Coolin g Syste m Servic e

The cooling system should be serviced at the intervals specified in the Maintenance Schedule as

follows:
Wash the radiator cap and filler
neck with clean water.
Check the engine coolant level

in the radiator and have it tested
for freeze protection. Add
ethylene glycol antifreeze, if
needed, to maintain freeze

protection at —33°F (—36°C).
Have the cooling system and
radiator cap tested for a pressure capacity of 15 psi (105
kPa). If a replacement cap is
needed, use a cap specified for
your model. Tighten all radiator and heater
hose clamps and inspect all
hoses. Replace the hoses if they
are swollen, "checked," or
otherwise worn. Carefully tighten the hose clamps at the
radiator. Overtightening could bend or collapse the radiator

fittings. Clean the front of the radiator
core and air conditioning

condenser.

It is the owner's responsibility to: Maintain the cooling system
freeze protection at —33°F
Car e an d Maintenanc e

Removing the radiator cap
while the engine is hot can
cause the coolant to spray out, seriously scalding you.
Always let the engine andradiator cool down beforeremoving the radiator cap.

If the diaphragm inside the
reservoir cap is deformed, return
it to the original (collapsed)
condition, then tighten the cap.
It is normal for the brake fluid
level to go down slightly as the
front brake pads wear. So be sure
to keep the reservoir fluid at the
proper level.
If the reservoir needs frequent
refilling, it may indicate a serious mechanical problem.
Brake fluid absorbs water from
the air. Never use brake fluid that
has been open to the air for an
extended period. Throw it away and use new brake fluid from a
sealed container.

Brake fluid can damage your vehicle's paint. Thoroughly clean
up any brake fluid spills.
Shift-on-the-Fl
y Syste m
The fluid level in the system should
be checked at the intervals shown in the Maintenance Schedule.
Remove the filler plug and make sure the fluid level is up to the
edge of the hole. If it is not, add
GL-5 gear oil to bring to that level. Use the same GL-5 gear oilspecified for the front axle (see
page 212). Fron
t Whee l Bearing s
Clean and repack the front wheel
bearings whenever the front brake
pads are replaced. Due to the weight of the tire and wheel
assembly it is recommended that
they be removed from the hub
before lubricating the bearings to
prevent damage to the oil seal.
"Long Fiber" grease should not be
used to lubricate the wheel bearings.
It can cause damage. Clean the old
grease out of the bearings and hubs
before repacking.

Check the complete exhaust
system and nearby body areas for
damaged, missing, or
mispositioned parts, open seams, holes, loose connections, or other
deterioration that could allow
exhaust fumes to seep into the
passenger compartment or cause
heat build-up in the floor pan. Any
necessary corrections should be made immediately. For continuedsafety, exhaust system pipes and
resonators rearward of the muffler must be replaced whenever a new
muffler is installed.

maintain them. This section
summarizes how the emissions
controls work. Scheduled
maintenance is on page 200.
Crankcas e Emission s
Contro l Syste m
Your vehicle has a Positive
Crankcase Ventilation System.
This keeps gasses that build up in the engine's crankcase from goinginto the atmosphere. The Positive
Crankcase Ventilation valve
routes them from the crankcase
back to the intake manifold. They are then drawn into the engine and

burned.

Evaporativ e Emission s
Contro l Syste m
As gasoline evaporates in the fuel
tank, an evaporative emission
control canister filled with charcoal adsorbs the vapor. It is stored in this canister while the
engine is off. After the engine is
started and warmed up, the vapor
is drawn into the engine and
burned during driving.
Exhaus t Emission s Control s
The exhaust emission controls include four systems: Fuel
Injection, 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 emission
control systems are separate fromthe crankcase and evaporative
emission control systems. Fuel Injection System
The Fuel Injection System uses sequential multiport fuel injection.
It has three subsystems: Air
Intake, Engine Control, and Fuel
Control. The Engine Control Module (ECM) 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 System This system constantly adjusts theignition timing, reducing the amount
of HC, CO and NOx produced.
