climate control HONDA ODYSSEY 2003 RB1-RB2 / 3.G User Guide

You can manually select various
f unctions of the Climate Control
system when it is in FULL AUTO.
All other f eatures remain auto-
matically controlled. Some of these
f unctions appear in the Navigation
System display. Press the A/C
button next to the display to show
these functions.
Pressing ‘‘ON’’ or ‘‘OFF’’ in the
display turns the air conditioning on

When you turn the A/C of f , the
system cannot regulate the inside
temperature if you set it below the
outside temperature. With the A/C
on, use the temperature buttons to
adjust the temperature of the air
flow to a comfortable setting.

Your vehicle has two controls f or the
rear A/C unit. The rear A/C control
dial is located on the climate control
panel, and the rear A/C passenger
control panel is on the ceiling behind
the driver’s seat.
You can adjust the heating, cooling,
and air f low of the rear A/C unit with
these control dials. The rear
passengers can also adjust the
direction and the amount of air f low
with the rear ceiling vents. Rear A/C Unit

Draining the coolant requires access
to the underside of the vehicle.
Unless you have the tools and
knowledge, you should have this
maintenance done by a skilled
mechanic.Turn the ignition ON (II). Turn

Check the condition of the two drive
belts (power steering belt and
alternator belt). Examine the edges
of each belt f or cracks or f raying. If you see signs of wear or looseness,
have your dealer adjust or replace
the belts. Power steering belt: Thebeltshouldhavethefollowing

Check the tension of the power
steering belt by pushing on it with
your thumb midway between the
pulleys.
The dust and pollen f ilter removes
pollen and dust that is brought in
f rom the outside through the heating
and cooling system/climate control
system.
This f ilter should be replaced every
30,000 miles (48,000 km) under
normal conditions. It should be
replaced every 15,000 miles (24,000
km) if you drive primarily in urban
areas that have high concentrations
of soot in the air f rom industry and
diesel-powered vehicles. Replace it
more of ten if air f low f rom the
heating and cooling system/climate
control system becomes less than
usual. Have the dust and pollen f ilter
replaced by your Honda dealer.

If your vehicle’s battery has run
down,youmaybeabletostartthe
engine by using a booster battery.
Although this seems like a simple
procedure, you should take several
precautions.
You cannot start a Honda by pushing
or pulling it. To jump start your vehicle, f ollow
these directions closely:
Open the hood and check the
physical condition of the battery
(see page ). In very cold
weather, check the condition of
the electrolyte. If it seems slushy
or like ice, do not try jump starting
until it thaws.
Turn of f all the electrical acces-
sories: heater, A/C, climate
control, stereo system, lights, etc.
Put the transmission in Neutral or
Park, and set the parking brake. Connect one jumper cable to the
positive ( ) terminal on your
Honda’s battery. Connect the
other end to the positive ( )
terminal on the booster battery.

A battery can explode if you do
not follow the correct procedure,
seriously injuring anyone
nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery.
If a battery sits in extreme cold, the
electrolyte inside can f reeze.
Attempting to jump start with a f rozen
battery can cause it to rupture.

Your vehicle can overheat for several
reasons, such as lack of coolant or a
mechanical problem. The only
indication may be the temperature
gauge climbing to or above the red
mark. Or you may see steam or
spray coming f rom under the hood.
In either case, you should take
immediate action.Saf ely pull to the side of the road.
Put the transmission in Neutral or

If you see steam and/or spray
coming f rom under the hood, turn

The pointer of your vehicle’s
temperature gauge should stay in
the midrange under most conditions.

If Your Engine Overheats
T aking Care of t he Unexpect ed366
Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
Driving with the temperature gauge
pointer at the red mark can cause
serious damage to your engine.

Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. This
releases any remaining pressure in
the cooling system. After the
pressure releases, push down on
the cap and turn it until it comes
off.
Start the engine and set the
temperature control dial to
maximum (climate control to
FULL AUTO at 90°F/32°C). 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.Put the radiator cap back on
tightly. Run the engine and watch
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.

This indicator should come on when
the ignition switch is ON (II), and go
out af ter the engine starts. If it
comes on brightly when the engine
is running, it indicates that the
charging system has stopped
charging the battery.By eliminating as much of the
electrical load as possible, you can
drive several miles (kilometers)
before the battery is too discharged
to keep the engine running. Drive to
a service station or garage where
you can get technical assistance.
Immediately turn of f all electrical
accessories:radio,heater,A/C,
climate control, rear def ogger, cruise
control, etc. Try not to use other
electrically-operated controls such as
the power windows. Keep the engine
running and take extra care not to
stall it. Starting the engine will
discharge the battery rapidly.

µ
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.
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.
Quality grades can be f ound where
applicable on the tire sidewall
between the tread shoulder and the
maximum section width. For
example:
Warning: The traction grade
assignedtothistireisbasedon
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.
All passenger car tires must conf orm
to Federal Saf ety Requirements in
addition to these grades.
