2005 HONDA PILOT ECU

Honda requires that any trailer with
a total trailer weight of 1,000 lbs (455
kg) or more has 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.
If you choose electric brakes, be
sure they are electronically actuated.
Do not attempt to tap into your
vehicle’s hydraulic system. No
matter how successf ul it may seem,
any attempt to attach trailer brakes
to your vehicles hydraulic system
will lower braking ef f ectiveness and
create a potential hazard.
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 the
chains drag on the ground.
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.When towing a trailer, we
recommend that you carry a f ull-size
spare wheel and tire for your vehicle
and trailer. See page f or proper
tire size, page f or how to store a
full size wheel and tire, and page
f or inf ormation on changing a
flat tire.
Remember to unhitch the trailer
bef ore changing a f lat. Ask your
trailer sales or rental agency where
and how to store the trailer’s spare
tire. 217

The trailer tires and spare are in

others, take time to practice driving
maneuvers bef ore heading f or the
open road, and f ollow the guidelines
below.
Avoid towing a trailer during your
vehicle’s f irst 600 miles (1,000 km)
(see page ).
Drive slower than normal in all
driving situations, and obey posted
speed limits f or vehicles with trailers.
When towing a f ixed-sided trailer (e.
g., camper), do not exceed 55 mph
(88 km/h). At higher speeds, the
trailer may sway or affect vehicle
handling.
To prevent the transmission f rom
shif ting f requently, drive in the D
position.
The added weight, length, and
height of a trailer will af f ect your
vehicle’s handling and perf ormance,
so driving with a trailer requires
some special driving skills and
techniques. Towing perf ormance can be
af f ected by high altitude, high
temperature, or when climbing
steep grades. Theref ore, premium
fuelisrecommendedwhentowing
more than 3,500 lbs (1,590 kg).
When preparing to tow, and bef ore
driving away, be sure to check the
f ollowing:
The vehicle has been properly
serviced, and the tires, brakes,
suspension, cooling system, and
lights are in good operating
condition.
If you tow f requently, f ollow the
Severe Conditions maintenance
schedule.
The trailer has been properly
serviced and is in good condition.
All weights and loads are within
limits.
Thehitch,safetychains,andany
other attachments are secure.
All items in or on the trailer are
properly secured and cannot shif t

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 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.
