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 marked
area, 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.
Engine Oil Additives
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.
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.
Air Cleaner Filter

215Care and Maintenance
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.
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.

Have the fluid level in the
automatic transmission checked
during the regularly scheduled
maintenance at your Honda
dealer.
If you suspect an automatic
transmission fluid leak, take the
vehicle to your Honda dealer for
inspection and repair.
Transmission damage could result
if you let the fluid level get too
low.
Drain Intervals
The automatic transmission drain
interval is not time or mileage
dependent. It will vary according
to your driving habits and vehicle
usage.
Your dealer will check the
transmission fluid’s condition and
life expectancy during regularly
scheduled maintenance, and
inform you at what mileage it
should be changed. 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
Lubricant Additive (Part No.
8-01052-358-0) or equivalent.
Use the correct viscosity for the
existing ambient temperatures.

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 solution
should be used year-round. It has
many advantages such as:
•provides freezing protection as
low as –33
F (–36
C)
• provides boiling protection up
to 262
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 gauge See the Maintenance Schedule in
this section to find out when the
engine coolant must be replaced.
Checking the Coolant Level
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.
Engine Cooling System

218Care and Maintenance
You usually do not need to remove
the radiator cap to check the engine
coolant level.
Removing the radiator cap
while the engine is hot can
cause the coolant to spray
out, seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.
Adding Engine Coolant
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 antifreeze
is used, there is no need to add
extra inhibitors or additives. They
may be harmful to the proper
operation of the system.
Cooling System Service
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

220 Care and Maintenance
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-Fly System
The fluid level in the system should
be checked at the intervals shown
in the Maintenance Schedule.
FILLER
PLUG
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 oil
specified for the front axle (see
page 216).
Front Wheel Bearings
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.

222Care and Maintenance
Front (4WD Only) and Rear
Propeller Shaft
Lubricate the sliding yoke with
EP chassis grease. Lubricate
universal joints with grease
containing MoS
2 (molybdenum
disulfide-type grease) at the
intervals shown in the
Maintenance Schedule. Also
check the propeller shaft
flange-to-pinion bolts for proper
torque of 64 N⋅ m (46.3 lb-ft).
Most lubrication recommendations
and procedures for four-wheel drive-
equipped vehicles are the same
for the corresponding components
in conventional drive vehicles.
Exhaust System
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 continued
safety, exhaust system pipes and
resonators rearward of the muffler
must be replaced whenever a new
muffler is installed.
Fuel Line and Fuel Tank/Cap
Inspect the fuel tank, cap and lines
for damage that could cause
leakage. Inspect the fuel cap and
gasket for correct sealing ability
and indications of physical
damage. Replace any damaged or
malfunctioning parts.
Drive Belt
Check the belt driving the
alternator, power steering pump,
and air conditioning compressor.
Look for cracks, fraying, and
wear. Replace as necessary.
Timing Belt
The timing belt should normally
be replaced at the intervals shown
in the Maintenance Schedule.
Valve Clearance
Incorrect valve clearance will
result in increased engine noise
and lower engine output, thereby
adversely affecting engine
performance.
