Your vehicle’s exhaust contains
carbon monoxide gas. Carbon
monoxide should not enter the
vehicle in normal driving if you
maintain your vehicle properly and
f ollow the inf ormation on this page.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.
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. With a truck cap installed and the
back window open, engine exhaust
may enter the vehicle and cause a
hazardous condition. Keep the back
window tightly closed whenever you
drive with a truck cap installed.
If you must sit in your parked vehicle
with the engine running, even in an
unconf ined area, adjust the heating
and cooling system/climate control
system as f ollows:
Select the f resh air mode.
Select the mode.
Turn the f an on high speed.

This indicator displays the outside
temperature in Fahrenheit (U.S.
models) or Centigrade (Canadian
models).
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 19 mph (30 km/h).
The sensor delays the indicator
update until it reaches the correct
outside temperature. This may take
several minutes.
If the outside temperature is
incorrectly displayed, you can adjust
it up to 5°F in U.S. models ( 3°C
in Canadian models) warmer or cooler.
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. For
instructions and precautions on
checking the engine’s cooling
system, see page .
In certain weather conditions,
temperature readings near f reezing
(32°F, 0°C) could mean that ice is
f orming on the road surf ace.
When it reaches the desired value,
release the RESET button. You
should see the new outside
temperature displayed.
To adjust the outside temperature
indicator, make sure the outside
temperature indicator is shown in
thedisplay,thenpressandholdthe
RESET button f or 10 seconds (the
TRIP A or B is also reset). The
f ollowing sequence will appear f or 1

f ogging the windows. The system automatically selects the
proper mix of conditioned and/or
heated air that will, as quickly as
possible, raise or lower the interior
temperature to your pref erence.
When you set the temperature to its
lower limit ( ) or its upper limit
( ), the system runs at f ull
cooling or heating only. It does not
regulate the interior temperature.
In cold weather, the f an will not

The banks and surf ace under the
water provide good traction. The
water may hide hazards such as
rocks, holes, or mud.
Bef ore driving through water, stop,
get out if necessary, and make sure
that:
If you decide it is saf e to drive
through water, choose a suitable
speed, and proceed without shif ting,
changing speeds, stopping, or
shutting of f the engine.
Do not try to cross water at high
speeds, as this may cause severe
damage to the cooling system or
result in loss of control.
After driving through water, test
your brakes. If they got wet, gently
‘‘pump’’ them while driving slowly
until they operate normally.
If the water is deeper than the wheel
hubs, some additional service may
be required. This service is not
covered by your warranties.
The water is not f lowing too f ast.
Deep rushing water can sweep you
downstream. Even very shallow
rushingwatercanwashthe
ground f rom under your tires and
cause you to lose traction and
possibly roll over.
The banks are sloped so you can
drive out.
The water is not deep enough to
cover your wheel hubs, axles, or
exhaust pipe. You could stall and
not be able to restart your engine.
The water can also damage
important vehicle components. If you get stuck, and cannot get
unstuck with the VTM-4 system,
engage the VTM-4 Lock (see page
), and carefully try to go in the
direction (f orward or reverse) that
you think will get you unstuck. Do
notspinthetiresathighspeeds.It
will not help you get out and may
cause damage to the transmission or
VTM-4 system.
If you are still unable to f ree yourself ,
your vehicle is equipped with f ront
and rear tow hooks designed f or this
purpose (see page ). 299

If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
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 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 Long-lif e Anti-
f 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.

Make sure the engine and radiator
are cool.
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 any.
Clean up any spill immediately; it
could damage components in the
engine compartment.
Put the radiator cap back on, and
tighten it fully.
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 washer level indicator will come
on when the level is low (see page
).
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.
