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 power system is on.
1. Press the AUTO button.
2. Adjust the interior temperature us ing the temperature control dial.
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.
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 air 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% antifreeze 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: Honda Long Life Antifreeze/Coolant Type 2
■Reserve Tank
1Cooling System
NOTICE
Genuine Honda engine coolan t 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 with Honda anti freeze/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.

1. Make sure the engine and radiator are
cool.
2. Turn the radiator cap 1/8 turn counter-
clockwise and relieve any pressure in the
cooling system.
3. Push down and turn the radiator cap
counterclockwise 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 co olant 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 vehicle serviced at a
dealer.
u Only a properly trained technician can
refill the coolant an d check the system
for leaks.

Climate Control System Maintenance
Air Conditioning
To ensure proper and safe operation, the 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 conditio ning 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 an d pollen filter sooner when using your
vehicle in areas with high concentrations of dust.

u If the cooling fan is not operating,
immediately turn the power system off.
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, add coolant until it reaches the
MAX mark.
u If there is no coolan t 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, turn the power system on. If the Engine
Temperature Too Hot. Do Not Drive. Allow Engine To Cool. message does not
appear, resume driving. If it appears again, 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.
