check engine HONDA PILOT 2004 1.G User Guide

Your Honda is equipped with disc
brakes on all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. The ABS helps
you retain steering control when
braking very hard.The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their ef f ectiveness.
It also keeps your brake lights on all
the time, conf using drivers behind
you.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by taking your f oot of f the
accelerator and downshif ting to a
lower gear. Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they f eel
normal. If not, apply them gently and
f requently until they do. Be extra
cautious in your driving.

Your Pilot can be towed behind a
motorhome at legal highway speeds
up to 65 mph (100 km/h). Do not
exceed 65 mph (100 km/h) or severe
transmission damage will occur. To
avoid damage to the 4WD system, it
must be towed with all f our wheels
on the ground (f lat towing).
When purchasing a tow bar, make
sure you select a reputable
manuf acturer. Follow the
manufacturer’s attachment
instructions caref ully.
Perf orm the f ollowing procedure
everyday immediately bef ore you
begin towing. Otherwise severe
automatic transmission damage will
occur.Check the transmission f luid level
(see page ).

Leave the ignition switch in
ACCESSORY (I) so the steering
wheel does not lock. Make sure
the radio and any items plugged
into the accessory power
sockets are turned of f so you do
not run down the battery.
If you tow more than 8 hours in one
day, you should repeat the above
procedure at least every 8 hours
(when you stop f or f uel, etc.)

Maintenance Severe for Severe Conditions

Oil is a major contributor to your
engine’s perf ormance and longevity.
Always use a premium-grade 5W-20
detergent oil displaying the API
Certif ication Seal. This seal indicates
the oil is energy conserving, and that
it meets the American Petroleum
Institute’s latest requirements.Honda Motor Oil is the pref erred
5W-20 lubricant f or your vehicle. It is
highly recommended that you use
Honda Motor Oil in your vehicle f or
optimum engine protection. Make
sure the API Certif ication Seal says
‘‘For Gasoline Engines’’.
The oil viscosity or weight is
provided on the container’s label.
5W-20 oil is f ormulated f or year-
round protection of your Honda to
improve cold weather starting and
f uel economy.
Unscrew and remove the engine oil
fill cap on top of the valve cover.
Pour in the oil slowly and caref ully so
you do not spill. Clean up any spills
immediately. Spilled oil could
damage components in the engine
compartment. Install the engine oil
f ill cap and tighten it securely. Wait a
f ew minutes and recheck the oil level.
Do not f ill above the upper mark; you
could damage the engine. Recommended Engine Oil

Tighten it to:
Remove the oil f ilter and let the

Honda dealer) is required.
Install a new oil f ilter according to
the instructions that come with it. Turn of f the engine, let it sit f or
several minutes, then check the oil
level on the dipstick. If necessary,
add more oil.
Refill the engine with the recom-
mended oil.

) Improper disposal of engine
oil can be harmf ul to the environment.
If you change your own oil, please
dispose of the used oil properly. Put it
in a sealed container and take it to a
recycling center. Do not discard it in a
trash bin or dump it on the ground.

If Honda antif reeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporaryreplacement.Makesureit
is a high-quality coolant
recommended f or aluminum engines.
Continued use of any non-Honda
coolant can result in corrosion,
causing the cooling system to
malf unction or f ail. Have the cooling
system f lushed and ref illed with
Honda antif reeze/coolant as soon as
possible.If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
If the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to the MAX line.
Inspect the cooling system f or leaks.
Always use Honda All Season
Antif reeze/Coolant Type 2. This
coolant is pre-mixed with 50 percent
antif reeze and 50 percent water.
Never add straight antifreeze or
plain water. A dding Engine Coolant

RESERVE TANK
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.

When the radiator and engine are
cool, relieve any pressure in the
cooling system by turning the
radiator cap counterclockwise,
without pressing down.
Remove the radiator cap by
pushing down and turning
counterclockwise.The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
Pourthecoolantslowlyand
caref ully so you do not spill. Clean
up any spill immediately; it could
damage components in the engine
compartment.
Put the radiator cap back on and
tighten it.
Pour coolant into the reserve tank.
Fill it to half way between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Do not add any rust inhibitors or
other additives to your vehicle’s
cooling system. They may not be
compatible with the coolant or
engine components. Check the f luid level in the
windshield washer reservoir at least
monthly during normal use.
The low washer
level indicator will light when the
level is low.
Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather.
When you ref ill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer f luid
on a clean cloth. This will help to
condition them.
