Climate Control System
Using Automatic Climate Control
The automatic climate control system maintains the interior temperature you select.
The system also selects the proper mix of heated or cooled air that raises or lowers
the interior temperature to your preference as quickly as possible.
Use the system when the power system is on.
1. Press the AUTO button.
2. Adjust the interior temperature using the dr iver’s side or passenger’s side control
dial.
3. Press the (on/off) button to cancel.
■Switching between the recirculation and fresh air modes
Press the (recirculation) button and switch the mode depending on
environmental conditions.
Recirculation mode (indicator on): Recirculat es air from the vehicle’s interior through
the system.
Fresh air mode (indicator off): Maintains out side ventilation. Keep the system in
fresh air mode in normal situations.
1 Using Automatic Climate Control
If any buttons are presse d while using the climate
control system in auto, the function of the button
that was pressed wi ll take priority.
The AUTO indicator will go off, but functions
unrelated to the button th at was pressed will be
controlled automatically.
To prevent cold air from bl owing in from outside, the
fan may not start i mmediately when the AUTO
button is pressed.
If the interior is very warm, you can cool it down
more rapidly by partial ly opening the windows,
turning the system on auto, and setting the
temperature to low. Change the fresh mode to
recirculation mode until the temperature cools down.
When you set the temperat ure to the lower or upper
limit, Lo or Hi is displayed.
Pressing the button switches the climate control
system between on and off. When turned on, the
system returns to your last selection.
While ECON mode is active, the climate control
system may have reduced cooling performance.

Cooling System
This coolant is premixed with 50% an tifreeze and 50% water. Do not add any
straight antifreeze or water.
We recommend you check the engine coolant level every time you refuel. Check the
reserve tank first. If it is completely empty, also check the coolant level in the
radiator. Add the engine coolant accordingly.
1. Make sure the engine and radiator are cool.
2. Check the amount of coolant in the reserve
tank.
u If the coolant level is below the MIN
mark, add the specified coolant until it
reaches the MAX mark.
3. Inspect the cooling system for leaks.
Specified coolant: Ho nda Long Life Antifreeze/Coolant Type 2
■Reserve Tank
1Cooling System
NOTICE
Genuine Honda engine coolant is a 50/50 mixture of
antifreeze and water that can withstand freezing at
temperatures as low as a bout -31°F (-35°C). If your
vehicle is consistently subjected to temperatures
below this, the concentration of antifreeze in the
coolant should be increased. Consult a dealer for
details.
If Honda antifreeze /coolant is not available, you may
use another major brand of non-silicate coolant as a
temporary replacement. Check that it is a high quality
coolant recommended for aluminum engines.
Continued use of any non-Honda coolant can result
in corrosion, causing the cooling system to
malfunction or fail. Have the cooling system flushed
and refilled wi th Honda antifreeze /coolant as soon as
possible.
Do not add rust inhibitors or other additives to your
vehicle’s cooling system. They may not be compatible
with the coolant or with the engine components.
3WARNING
Removing the radiator cap while the
engine is hot can cause the coolant to spray
out, seriously scalding you.
Always let the engine and radiator cool
down before removing the radiator cap.

Maintenance
1. Make sure the engine and radiator are
cool.
2. Turn the radiator cap 1/8 turn counter-
clockwise to relieve any pressure in the
cooling system.
3. Push down and turn the radiator cap
counter-clockwise to remove it.
4. The coolant level should be up to the base
of the filler neck. Add coolant if it is low.
5. Put the radiator cap back on, and tighten it
fully.

We recommend you check the inverter coolant level every time you refuel.
Have a dealer replace the inverter coolant.
1.Check the fluid level in the tank.
2. If the coolant level has dropped below the
MIN level, have your ve hicle serviced at a
dealer.
u Only a properly trained technician can
refill the coolant and check the system
for leaks.

Climate Control System Maintenance
Air Conditioning
To ensure proper and safe operation, th e Society of Automotive Engineers (SAE
J2845) recommends that the refrigerant system only be serviced by trained and
certified technicians.
Never repair or replace the air conditioning evaporator (cooling coil) with one
removed from a used or salvaged vehicle.
New replacement mobile air conditioning evaporators must be certified (and
labeled) as meeting SAE Standard J2842.
Dust and Pollen Filter
The climate control system is equipped with a dust and pollen filter that collects
pollen, dust, and other debris in the air. The Maintenance MinderTM messages will let
you know when to replace the filter.
We recommend that you replace the dust a nd pollen filter sooner when using your
vehicle in areas with high concentrations of dust.
1 Air Conditioning
NOTICE
Vented refrigerant is harmful to the environment.
To avoid refrigerant from venting, never replace the
evaporator with one removed from a used or
salvaged vehicle.
Refrigerant in your vehicle’s air conditioning system is
flammable and can be igni ted during servicing if
proper procedures are not followed.
The air conditioner labe l is found under the hood:

reserve tank is low, add coolant until it
reaches the MAX mark.
u If there is no coolant in the reserve tank,
check that the radiator is cool. Cover the
radiator cap with a heavy cloth and open
the cap. If necessary, add coolant up to
the base of the filler neck, and put the
cap back on.
