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.Remove the engine compartment cover.
2 Engine Compartment Cover P. 529
2.Check the amount of coolant in the reserve
tank.
3. 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: Ho nda Long Life Antifreeze/Coolant Type 2
■Reserve Tank
1Engine Coolant
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 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. They may not be compatible
with the coolant or with the engine components.

Maintenance
1. Make sure the engine and radiator are
cool.
2. Remove the engine compartment cover.
2 Engine Compartment Cover P. 529
3.Turn the radiator cap counterclockwise and
relieve any pressure in the cooling system.
Do not push the cap down when turning.
4. Push down and turn the radiator cap
counterclockwise 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.
7. Pour coolant into the reserve tank until it
reaches the MAX mark. Put the cap back
on the reserve tank.
■Radiator1 Radiator
NOTICE
Pour the fluid slowly and ca refully so you do not spill
any. Clean up any spills immediately; they can
damage components in the engine compartment.
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.Radiator

Maintenance
Heating and Cooling System*/Climate Control System* Maintenance
Air Conditioning
To ensure proper and safe operation, the 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 heating and cooling system*/climate control system* is equipped with a dust
and pollen filter that collects pollen, dust, and other debris in the air. The
Maintenance Minder
TM 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.
1Heating and Cooling System*/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.
Air Conditioner label is found under the hood:

Handling the Unexpected
■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, remove the engine compartment
cover then add coolant until it reaches
the MAX mark.
2Engine Compartment Cover P. 529
uIf 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, restart it and check the temperature gauge.
If the temperature gauge needle has gone do wn, resume 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.

Indicator, Coming On/Blinking
If the Low Oil Pressure Indicator Comes On
■Reasons for the indicator to come on
Comes on when the engine oil pressure is low.
■What to do as soon as the indicator comes on
1. Immediately park the vehicle on level ground in a safe place.
2. If necessary, turn the hazard warning lights on.
■What to do after parking the vehicle
1. Stop the engine and let it sit for about three minutes.
2. Open the hood and check the oil level.
u Add oil as necessary.
2 Oil Check P. 531

u The indicator goes off: Start driving again.
u The indicator does not go out within 10 seconds: Stop the engine
and contact a dealer for repairs immediately.
If the Charging System Indicator Comes On
■Reasons for the indicator to come on
Comes on when the battery is not being charged.
■What to do when th e indicator comes on
Turn off the climate control system*/heating and cooling system*, rear
defogger, and other electrical system s, and immediately contact a dealer
for repairs.
1 If the Low Oil Pressure Indicator Comes On
NOTICE
Running the engine with low oil pressure can cause
serious mechanical damage almost immediately.
1If the Charging System Indicator Comes On
If you need to stop temporarily, do not turn off the
engine. Restarting the engi ne may rapidly discharge
the battery.
