4. Set the temperature to maximum heat.
■Cooling1To rapidly cool down the interior
If the interior is very warm, you can cool it down
more rapidly by partially opening the windows.
While in the ECON mode, the system has greater
temperature fluctuations.
Pressing the button bypasses the ECON mode
control, and cools down the interior more rapidly.
■Defrosting the Windshield and Windows1Defrosting the Windshield and Windows
For your safety, make sure you have a clear view
through all the windows before driving.
Do not set the temperature near the upper or lower
limit.
When cold air hits the windshield, the outside of the windshield may fog up.
If the side windows fog up, adjust the vents so that
the air hits the side windows.
1To rapidly defrost the windows
After defrosting the windows, switch over to fresh air
mode.
If you keep the system in recirculation mode, the
windows may fog up from humidity. This impedes
visibility.

uuTowing a TraileruDriving Safely with a Trailer
Driving
Driving Safely with a Trailer •Have the trailer properly serviced and keep it in good condition.
• Make sure that all the weights and load in the vehicle and trailer are within limits.
2 Towing Load Limits P. 231
• Securely attach the hitch, safety chains, and other necessary parts to the trailer.
• Securely store all the items in and on the trailer so that they do not shift while
driving.
• Check if the lights and brakes on the trailer are working properly.
• Check the pressures of the trailer tires, including the spare.
• Drive slower than normal.
• Obey posted speed limits for vehicles with trailers.
• Use the
(D position when towing a trailer on level roads.
• Turn more slowly and with a wider turning arc than normal.
• Allow more time and distance for braking.
• Do not brake or turn suddenly.
• Monitor your temperature gauge. If it nears the red (Hot) mark, turn off the
heating and cooling system *
/climate control system *
and reduce speed. Pull to the
side of the road safely to cool down the engine if necessary.
• Shift to the
(d position if the transmission shifts frequently.

Starting the Engine
1.Make sure the parking brake is applied.
2. Check that the shift lever is in

without depressing the accelerator pedal.
1Starting the Engine
Keep your foot firmly on the brake pedal when
starting the engine.
The engine is harder to start in cold weather and in
thinner air found at altitudes above 8,000 feet (2,400 meters).
When starting the engine in cold weather, turn off all
electrical accessories such as the lights, heating and
cooling system *
/climate control system *
, and rear
defogger in order to reduce battery drain.
If the exhaust system sounds abnormal or you can
smell exhaust gas inside the vehicle, have your vehicle
checked by a dealer. There may be a problem with
the engine or exhaust system.
Do not hold the key in START
(e for more than 15
seconds.
• If the engine does not start right away, wait for at
least 10 seconds before trying again.
• If the engine starts, but then immediately stops,
wait at least 10 seconds before repeating step 3
while gently depressing the accelerator pedal.
Release the accelerator pedal once the engine starts.
The immobilizer system protects your vehicle from
theft. If an improperly coded key (or other device) is
used, the engine's fuel system is disabled. 2 Immobilizer System P. 106

Automatic Transmission
The following conditions cause the engine to run at high revolutions, and increase creeping: •Immediately after the engine starts.
• When the heating and cooling system *

is in use.
Keep the brake pedal firmly depressed when stopped.
Quickly depressing the accelerator pedal while driving uphill may cause the
transmission to drop to a lower gear, unexpectedly increasing vehicle speed. Depress
the accelerator pedal carefully, especially on slippery roads and curves.

uuMaintenance Under the HooduEngine Coolant
Maintenance
Engine Coolant
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.Check the amount of coolant in the reserve tank.
2. 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
1Engine Coolant
NOTICEYou will need a more concentrated coolant if you are
driving in extremely cold temperature below −31°F
(−35°C). Consult your Honda dealer for details about
a suitable coolant mixture.
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 antifreeze/coolant as soon as
possible.
Do not add rust inhibitors or other additives to your
vehicle's coolant system. They may not be compatible
with the coolant or with the engine components.

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.

deteriorates noticeably, and
the windows fog up easily, the filter may need to be
replaced. Please contact a dealer for replacement.

Handling the Unexpected
■ Next thing to do
1.Check that the cooling fan is operating and
stop the engine once the temperature
gauge needle comes down.
uIf 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.
uIf the coolant level in the reserve tank is
low, add coolant until it reaches the
MAX mark.
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, restart it and check the temperature gauge.
If the temperature needle has gone down, resume driving. If it has not gone down,
contact a dealer for repairs.
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.
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.
