Controls
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 h eated or cooled air that will as quickly as
possible, raise or lower the interior temperature to your preference.
Use the system when the engine is running.
1. Press the AUTO button.
2. Adjust the interior temperature using the driver’s side or passenger’s side
temperature control switch.
3. Press the ON/OFF button to cancel.1Using 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 will take priority.
The AUTO indicator will go off, but functions
unrelated to the button th at was pressed will be
controlled automatically.
During Auto Idle Stop, air- conditioning is suspended,
and only the blower remains active.
If you do not want air-cond itioning suspended, press
the Auto Idle Stop OFF button to cancel Auto Idle
Stop.
To prevent cold air from bl owing in from outside, the
fan may operate at low speed for a while after the
AUTO button has been pressed.
While ECON mode is active, the climate control
system may have reduced cooling performance.
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 temperature to the lower or upper
limit, Lo or Hi is displayed.

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 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. Remove the engine compartment cover.
2 Engine Compartment Cover P. 511
3.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.
4. Inspect the cooling system for leaks.
Specified coolant: Honda Long Life Antifreeze/Coolant Type 2
■Reserve Tank
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. Th ey 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.

3.Turn the radiator cap 1/8 turn counter-
clockwise and relieve any pressure in the
cooling system. Do not push the cap down
when turning.
4. Push down and turn the radiator cap
counter-clockwise to remove it.
5. The coolant level should be up to the base
of the filler neck. Add coolant if it is low.
6. Put the radiator cap back on, and tighten it
fully.

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 J2842.1 Climate 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.

Handling the Unexpected
■Next thing to do
1.Check that the cooling fan is operating and
stop the engine once the temperature
gauge 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 and check the cooling
system components for leaks.
u If the coolant level in the reserve tank is
low, remove the engine compartment
cover then add coolant until it reaches
the MAX mark.
2Engine Compartment Cover P. 511
uIf 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.
■Last thing to do
Once the engine has cooled sufficiently, re start it and check the temperature gauge.
If the temperature gauge has gone down, resu me driving. If it has not gone down,
contact a dealer for repairs.
1 How 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.
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.
