2009 HONDA ACCORD SEDAN climate control

When the indicator in the dual
button is on, the driver’s side and
passenger’s side temperature can be
controlled independently (see page).
When you set the temperature to its
lower limit ( ) or its upper limit
( ), the system runs at f ull
cooling or heating only. It does not
regulate the interior temperature.
When you adjust a f an control, the
f an is taken out of AUTO mode.
In AUTO mode, the vehicle’s interior
temperature is independently
regulated f or the driver and f ront
passenger according to each
adjusted temperature. The system
also regulates each temperature
basedontheinformationof thesun
light sensor and the sun’s position
which is updated automatically by
the navigation’s global positioning system (GPS). If one side of the
vehicle is getting too much sun, the
system lowers the temperature only
on that side.
You can set the temperatures for the
driver’s side and the passenger’s side
separately when this button is
pressed (indicator is on). When the
indicator in the DUAL button is of f ,
the temperatures for both sides are
synchronized to the driver’s side set
temperature. When def rost mode is
selected, dual mode operation is
canceled.
If you press the OFF button, the
climate control system shuts of f
completely.
Keep the system completely of f
f or short periods only.
To keep stale air and mustiness
f rom collecting, you should have
the f an running at all times.

on, air f rom the vehicle’s interior is
sent through the system again.
When the indicator is off, air is
brought in f rom the outside of the
vehicle (fresh air mode).
Switch to recirculation mode when
driving through dusty or smoky
conditions, then return to fresh air
mode.

Keeping the system in recirculation
mode, particularly with the A/C of f ,
can cause the windows to fog up.
The outside air intakes f or the
climate control system are at the
base of the windshield. Keep this
area clear of leaves and other debris.
You can manually select various
f unctions of the climate control
system when it is in f ully automatic
mode. All other f eatures remain
automatically controlled. Making any
manual selection causes the word
AUTO in the display to go out.

Have your dealer replace this filter
when this service is indicated by a
maintenance message on the

replaced every 15,000 miles (24,000
km) if you drive primarily in urban
areas that have high concentrations
of soot in the air, or if the airf low

Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. Af ter the
pressure releases, push down on
the cap, and turn it until it comes
off.Put the radiator cap back on
tightly. Run the engine, and check
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (see
on page ).
If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly.
If you do not f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.
If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the pointer
reaches the middle of the tempera-
ture gauge, or lower, bef ore check-
ing the radiator.
Start the engine, and set the
temperature to maximum heat
(climate control to AUTO at
‘‘ ’’). Add coolant to the
radiator up to the base of the f iller
neck. If you do not have the
proper coolant mixture available,
you can add plain water.
Remember to have the cooling
system drained and ref illed with
the proper mixture as soon as you
can.

Quality grades can be f ound where
applicable on the tire sidewall
between tread shoulder and
maximum section width. For
example:The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specif ied government
test course. For example, a tire
graded 150 would wear one and one-
half (1 1/2) times as well on the
government course as a tire graded
100. The relative perf ormance of
tires depends upon the actual condi-
tions of their use, however, and may
depart signif icantly f rom the norm
due to variations in driving habits,
service practices and dif f erences in
road characteristics and climate.The traction grades, f rom highest to
lowest, are AA, A, B, and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on
specif ied government test surf aces
of asphalt and concrete. A tire
marked C may have poor traction
perf ormance.
Warning: The traction grade
assignedtothistireisbasedon
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.
The tires on your vehicle meet all
U.S. Federal Saf ety Requirements.
All tires are also graded f or
treadwear, traction, and temperature
perf ormance according to
Department of Transportation
(DOT) standards. The f ollowing
explains these gradings.
All passenger car tires must conf orm
to Federal Saf ety Requirements in
addition to these grades.

ÎThe 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. 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.
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
crankcase 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 .
