2003 HONDA PILOT maintenance

Two f actors normally contribute to
causing corrosion in your vehicle:Moisture trapped in body cavities.
Dirtandroadsaltthatcollectsin
hollows on the underside of the
vehicle stays damp, promoting
corrosion in that area.
Removal of paint and protective
coatings f rom the exterior and
underside of the vehicle. Repair chips and scratches in the
paint as soon as you discover them.
Inspect and clean out the drain
holes in the bottom of the doors
and body.
Check the f loor coverings f or
dampness. Carpeting and f loor
mats may remain damp f or a long
time, especially in winter. This
dampness can eventually cause
the f loor panels to corrode.Use a high-pressure spray to clean
the underside of your vehicle. This
is especially important in areas
that use road salt in winter. It is
also a good idea in humid climates
and areas subject to salt air. Be
caref ul of the ABS wheel sensors
and wiring at each wheel.
Have the corrosion-preventive
coatings on the underside of your
vehicle inspected and repaired
periodically.
Many corrosion-preventive measures
are built into your Honda. You can
help keep your vehicle f rom
corroding by perf orming some
simple periodic maintenance:

The burning of gasoline in your
vehicle’s engine produces several by-
products. Some of these are carbon
monoxide (CO), oxides of nitrogen
(NOx) and hydrocarbons (HC).
Gasoline evaporating f rom the tank
also produces hydrocarbons. Con-
trolling the production of NOx, CO,
and HC is important to the environ-
ment. Under certain conditions of
sunlight and climate, NOx and HC
react to f orm photochemical ‘‘smog.’’
Carbon monoxide does not contri-
bute to smog creation, but it is a
poisonous gas.
In Canada, Honda vehicles comply
with the Canadian emission
requirements, as specif ied in an
agreement with Environment
Canada, at the time they are
manuf actured.
Your vehicle has a Positive
Crankcase Ventilation System. This
keeps gasses that build up in the
engine’s crankcase f rom going into
the atmosphere. The Positive Crank- case Ventilation valve routes them
from the crankcase back to the
intake manif old. They are then
drawn into the engine and burned.
As gasoline evaporates in the f uel
tank, an evaporative emissions
control canister f illed with charcoal
adsorbs the vapor. It is stored in this
canister while the engine is of f . Af ter
the engine is started and warmed up,
the vapor is drawn into the engine
and burned during driving.
The Onboard Ref ueling Vapor
Recovery (ORVR) system captures
the f uel vapors during ref ueling. The
vapors are adsorbed in a canister
f illed with activated carbon. While
driving, the f uel vapors are drawn
into the engine and burned of f .
The United States Clean Air Act
sets standards f or automobile
emissions. It also requires that
automobile manufacturers explain to
owners how their emissions controls
workandwhattodotomaintain
them. This section summarizes how
the emissions controls work.
