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.
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 under-
side. 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. With the tailgate/hatch glass open,
air flow can pull exhaust gas into
your vehicle’s interior and create a
hazardous condition. If you must
drive with the tailgate/hatch glass
open, open all the windows and set
the heating and cooling system as
shown below.
If you must sit in your parked vehicle,
even in an unconf ined area, with the
engine running, 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.

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
page f or instructions and
precautions on checking the engine’s
cooling system.
The temperature sensor is in the
f ront bumper. Theref ore, the
temperature reading can be af f ected
by heat ref lection f rom the road
surf ace, engine heat, and the
exhaust f rom surrounding traf f ic.
This can cause an incorrect
temperature reading when your
speed is under 30 km/h.If the outside temperature is
incorrectly displayed, you can adjust
it up to 3°C warmer or cooler.
NOTE: The temperature must be
stabilized bef ore doing this
procedure.
Select the outside temperature
display, then press the Select/Reset
knob f or ten seconds. The f ollowing
sequence will appear f or one second
each:0,1,2,3,4,5, 5, 4, 3, 2,
1, 0, 1 (0, 1, 2, 3, 3, 2, 1, 0, 1).
When it reaches the desired value,
release the Select/Reset knob. You
should see the new outside
temperature displayed.

If the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to the MAX line.
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.
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.

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.

When the radiator and engine are
cool, relieve any pressure in the
cooling system by turning the
radiator cap counterclockwise,
without pressing down.
Remove the radiator cap by
pushing down and turning
counterclockwise.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.
