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 pr eference as quickly as possible.
Use the system when the engine is running.
1. Press the AUTO button.
2. Adjust the interior temperature us ing the temperature control dial.
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.1Using Automatic Climate Control
Press the CLIMATE button to display A/C, MODE,
fan control information on the audio/information
screen to operate manually. Select ic on to turn on or
off A/C , change the vent mode , or change the fan
speed.
If any buttons are presse d while using the climate
control system in auto, the function of the button
that was pressed will take priority.
The AUTO indicator will go off, but functions
unrelated to the button that were 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.

Maintenance
Engine Coolant
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. 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
■Checking the Coolant
1.5 L engine models
1Engine Coolant
NOTICE
Genuine Honda engine coolant is a 50/50 mixture of
antifreeze and water that can withstand freezing at
temperatures as low as about -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 with
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 reserve tank 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 reserve tank
cap.

Maintenance
Climate Control System Maintenance
Air Conditioning
To ensure proper and safe operation, th e Society of Automotive Engineers (SAE
J2845) recommends that the refrigerant sy stem 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 wi th 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 and pollen filter sooner when using your
vehicle in areas with high concentrations of dust.
1Climate Control System Maintenance
NOTICE
Vented refrigerant is harmful to the environment.
To avoid refrigerant from venting, never replace the
evaporator with one re moved 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.

If the airflow from the climate control system
deteriorates noticeably, and the windows fog up
easily, the filter may need to be replaced. Please
contact a dealer for replacement.

■Next thing to do
1.Check that the cooling fan is operating and
stop the engine once the temperature
gauge needle goes down.
u If the cooling fan is not operating,
immediately stop the engine.
2. Once the engine has cooled down, inspect
the coolant level, an d check the cooling
system components for leaks.
u If the coolant level, in the reserve tank is
low, or no coolant in the tank, check that
the radiator is cool. Cover the reserve
tank cap with a heavy cloth and open the
cap. Add coolant until it reaches the
MAX mark and put the cap back on.1How to Handle Overheating
If the coolant is leaking, contact a dealer for repairs.
Use water as an emergency/temporary measure only.
Have a dealer flush the system with proper antifreeze
as soon as possible.

■Last thing to do
Once the engine has cooled sufficiently, restart it, and check the temperature
gauge.
If the temperature gauge needle has gone dow n, resume driving. If it has not gone
down, contact a dealer for repairs.
