2004 HONDA PILOT ECU

Your vehicle has a higher ground
clearance that allows you to travel
over bumps, obstacles, and rough
terrain. It also provides good
visibility so you can anticipate
problems earlier.
Because your vehicle rides higher
of f the ground, it has a high center
of gravity that can cause it to roll
over if you make abrupt turns. Utility
vehicles have a signif icantly higher
roll over rate than other types of
vehicles.
To prevent rollovers or loss of
control:Take corners at slower speeds
than you would with a passenger
vehicle.
Avoid sharp turns and abrupt
maneuvers whenever possible. When you start the engine, check
the gauges and indicator lights in
the instrument panel (see page
).
Make sure the doors and the
tailgate are securely closed and
locked. Check the steering wheel
adjustment (see page ). Check the adjustment of the
inside and outside mirrors (see
page ). Check the seat adjustment (see
page ). Check that any items you may be
carrying are stored properly or
f astened down securely.
Visually check the tires. If a tire
looks low, use a gauge to check its
pressure. Make sure all windows, mirrors,
and outside lights are clean and
unobstructed. Remove f rost, snow,
or ice.
Youshoulddothefollowingchecks
and adjustments bef ore you drive
your vehicle. Do not carry heavy cargo on the
roof . Do not modif y your vehicle in any
way that would raise the center of
gravity.
Fasten your seat belt. Check that
your passengers have f astened
their seat belts (see page ).

Towing generally requires a variety
of supplemental equipment. To
ensure the best quality, we
recommend that you purchase
Honda equipment whenever possible.
Discuss any additional needs with
your trailer sales or rental agency,
and make sure all equipment is
properly installed, maintained, and
also meets state regulations.
We strongly recommend that you
have your Honda dealer install a
Honda hitch and use the required
f luid coolers. Using non-Honda
equipment may result in serious
damage to your vehicle.
A weight distributing hitch is not
recommended f or use with your Pilot.Honda requires that any trailer with
a total trailer weight of 1,000 lbs (455
kg) or more have its own brakes.
There are two common types of
trailer brakes: surge and electric.
Surge brakes are common f or boat
trailers, since the brakes will get wet.
Electric brakes must be
electronically actuated. Do not
attempt to tap into your vehicle’s
hydraulic system. See your brake
manuf acturer f or more inf ormation
on installing electric brakes.
Always use saf ety chains when you
tow a trailer. Make sure the chains
are secured to the trailer and hitch,
and that they cross under the tongue
and can catch the trailer if it
becomes unhitched. Leave enough
slack to allow the trailer to turn
corners easily, but do not let thechains drag on the ground.
To help prevent overheating, a
heavy-duty transmission f luid cooler
and a heavy-duty power steering
f luid cooler are required f or trailer
towing. These coolers are available
only f rom your Honda dealer.
This device is recommended if your
trailer tends to sway. Your trailer
maker can tell you what kind of sway
control you need and how to install it.
Many states and provinces require
special exterior mirrors when towing
a trailer. Even if they don’t, you
should install special mirrors if you
cannot clearly see behind you, or if
the trailer creates a blind spot.

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

To thoroughly f lush the
transmission, the technician
should drain and ref ill it with
Honda ATF-Z1 (Automatic
Transmission Fluid), then drive
the vehicle f or a short distance.
Do this three times. Then drain
and ref ill the transmission a f inal
time.
Insert the dipstick all the way back
into the transmission.
The transmission should be drained
and ref illed with new f luid according
to the time and distance recommen-
dations in the maintenance schedule.
If you are not sure how to add f luid,
contact your Honda dealer. Put a new washer on the f iller bolt,
then reinstall the f iller bolt and
tighten it securely. Tightening

The dif f erential should be drained
and ref illed with new f luid according
to the time and distance recommen-
dations in the maintenance schedule.
The timing belt should be replaced
at the intervals shown in the
maintenance schedule. Replace the
belt at 60,000 miles (100,000 km) if
you regularly drive your vehicle in
one or more of these conditions:
In very high temperatures
(over 110°F, 43°C).
In very low temperatures
(under 20°F, 29°C).
Frequently tow a trailer.
Check the f luid level with the
dif f erential at normal operating
temperature and the vehicle sitting
on level ground. Remove the
dif f erential f luid f iller bolt and
washer, and caref ully f eel inside the
bolt hole with your f inger. The f luid
level should be up to the edge of the
bolt hole. If it is not, slowly add
VTM-4 Dif f erential Fluid until it
starts to run out of the hole.
