Your vehicle’s exhaust contains
carbon monoxide gas. You should
have no problem with carbon
monoxide entering the vehicle in
normal driving if you maintain your
vehicle properly.High levels of carbon monoxide can
collect rapidly in enclosed areas,
such as a garage. Do not run the
engine with the garage door closed.
Even with the door open, run the
engine only long enough to move the
vehicle out of the garage.If you must sit in your parked vehicle
with the engine running, even in an
unconf ined area, adjust the heating
and cooling system as f ollows:
Select the Fresh Air mode.
Select the mode.
Turn the f an on high speed.
Set the temperature control to a
comfortable setting.
With the trunk open, airf low can pull
exhaust gas into your vehicle’s
interior and create a hazardous
condition. If you must drive with the
trunk open, open all the windows,
and set the heating and cooling
system as shown below.
Have the exhaust system inspected
f or leaks whenever:
The vehicle is raised f or an oil
change.
You notice a change in the sound
of the exhaust.
The vehicle was in an accident
that may have damaged the
underside. 1.

This shows the temperature of the
engine’s coolant. During normal
operation, the pointer should rise to
about the middle of the gauge. In
severe driving conditions, the pointer
may rise to the upper zone. If it
reaches the red (Hot) mark, pull
safely to the side of the road. Turn to

If Honda antif reeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporaryreplacement.Makesureit
is a high-quality coolant
recommended f or aluminum engines.
Continued use of any non-Honda
coolant can result in corrosion,
causing the cooling system to
malf unction or f ail. Have the cooling
system f lushed and ref illed with
Honda antif reeze/coolant as soon as
possible.If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
If the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to between the
MIN and MAX lines. Inspect the
cooling system f or leaks.
Always use Honda All Season
Antif reeze/Coolant Type 2. This
coolant is pre-mixed with 50 percent
antif reeze and 50 percent water.
Never add straight antifreeze or
plain water.

RESERVE TANK
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.

The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
Pourthecoolantslowlyand
caref ully so you do not spill. Clean
up any spill immediately; it could
damage components in the engine
compartment.
Put the radiator cap back on and
tighten it.
Pour coolant into the reserve tank.
Fill it to half way between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Do not add any rust inhibitors or
other additives to your vehicle’s
cooling system. They may not be
compatible with the coolant or
engine components. Check the f luid level in the
windshield washer reservoir at least
monthly during normal use.
The low washer
level indicator comes on when the
level is low (see page ).
Make sure the engine and radiator
are cool.
Remove the radiator cap by
pushing down and turning
counterclockwise. Relieve any pressure in the cooling
system by turning the radiator cap
counterclockwise, without
pressing down. Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather.
When you ref ill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer f luid
on a clean cloth. This will help to
condition them.

Do not use engine antif reeze or a
vinegar/water solution in the
windshield washer reservoir. Antif reeze
can damage your vehicle’s paint, while
a vinegar/water solution can damage
the windshield washer pump. Use only
commercially-available windshield
washer f luid.

Dirt build-up in the loops of the seat
belt anchors can cause the belts to
retract slowly. Wipe the insides of
the loops with a clean cloth
dampened in mild soap and warm
water or isopropyl alcohol.This f ilter removes the dust and
pollenthatisbroughtinfromthe
outside through the heating and
cooling system.
If your seat belts get dirty, use a sof t
brush with a mixture of mild soap
and warm water to clean them. Do
not use bleach, dye, or cleaning
solvents. Let the belts air dry bef ore
you use the vehicle. The driver’s f loor mat that came

If you remove the driver’s f loor mat,
make sure to re-anchor it when you

Have your dealer replace this filter
every 30,000 miles (48,000 km)
under normal conditions. It should
be replaced every 15,000 miles
(24,000 km) if you drive primarily in
urban areas that have high
concentrations of soot in the air, or if
the f low f rom the heating and
cooling system becomes less than
usual.
