Gauges

TACHOMETER

Speedometer
U.S. Models

This shows your speed in miles per
hour (mph). The smaller inner
numbers are the speed in kilometers

per hour (km/h).

Canadian Models
This shows your speed in kilometers per hour (km/h). The smaller inner
numbers are the speed in miles per
hour (mph). Odometer
The odometer shows the total dis- tance your vehicle has been driven.
It measures miles in U.S. models and
kilometers in Canadian models. It is illegal under federal law (in the
U.S.) and provincial regulations (inCanada) to disconnect, reset, or alter
the odometer with the intent to change the number of miles or
kilometers indicated. Temperature Gauge
This shows the temperature of the engine's coolant. During normal
operation, the pointer should rise
from the bottom white mark to about the middle white mark. In severedriving conditions, such as very hot
weather or a long period of uphill driving, the pointer may rise to the
upper white mark. If it reaches the
red (Hot) mark, pull safely to the side of the road. Turn to page 204 for
instructions and precautions on
checking the engine's cooling
system.

Fuel Gauge
This shows how much fuel you have. It is most accurate when the vehicle
is on level ground. It may show slightly more or less than the actual
amount when you are driving on
curvy or hilly roads.

Heating and Cooling

Vent Controls
You can adjust the direction of the air coming from the dashboard vents
by moving the tab in the center of
each vent up-and-down and side-to-

side.
CORNER VENT
The vents in the corners of the dashboard can be opened and closed
with the dials next to them. How to Use the System
This section covers how to set up the system controls for ventilation,
heating, cooling, dehumidifying, and defrosting.
The engine must be running for the heater and air conditioning to
generate hot and cold air. The heateruses engine coolant to warm the air.
If the engine is cold, it will be several
minutes before you feel warm air
coming from the system.
The air conditioning does not rely on engine temperature.

Heating and Cooling

To Cool with A/C
1. Turn on the A/C by pressing the button. The light in the button
should come on.
2. Make sure the temperature control lever is all the way to the
left.
3. Select and Fresh Air mode.

4. If the outside air is humid, select

Recirculation mode. If the outside

air is dry, select Fresh Air mode.

5. Set the fan to the desired speed.
If the interior is very warm from
being parked in the sun, you can cool it down more rapidly by setting up
the controls this way:
1. Start the engine.
2. Turn on the A/C by pressing the button. Make sure the tempera-
ture control lever is all the way to
the left.
3. Set the fan to maximum speed.
4. Open the windows partially. Select
and
When the interior has cooled down
to a more comfortable temperature,close the windows and set the
controls as described for normal

cooling.
Air conditioning places an extra load
on the engine. Watch the engine
coolant temperature gauge (see page 56) when driving in stop-and-go
traffic or climbing a long, steep hill. If it moves near the red zone, turn
off the A/C until the gauge reads
normally.

Heating and Cooling

These settings direct all the air flow
to the defroster vents at the base of
the windshield and the side window defroster vents. The air flow will get
warmer and clear the windows faster as the engine warms up. You can
close the corner vents with the dial
beside each vent. This will send
more warm air to the windshield defroster vents.
For safety, make sure you have a
clear view through all the windows
before driving away.

To Turn Everything Off

To shut off the system temporarily, slide the fan speed and temperature
control levers all the way to the left. You should shut the system
completely off only for the first few
minutes of driving in cold weather,
until the engine coolant warms up
enough to operate the heater. Keep
the fan on at all other times so stale air does not build up in the interior.

Cooling System

Replacing Engine Coolant
The cooling system should be completely drained and refilled with
new coolant according to the time
and distance recommendations in
the maintenance schedule. Only use Genuine Honda antifreeze/coolant.
Draining the coolant requires access
to the underside of the vehicle. Unless you have the tools and
knowledge, you should have this
maintenance done by a skilled
mechanic.

1. Slide the heater temperature
control lever to maximum heat.
Open the hood. Make sure the
engine and radiator are cool to the
touch.
2. Remove the radiator cap. 3. Loosen the drain plug on the
bottom of the radiator. Thecoolant will drain through the
splash guard. Remove the drain
bolt and washer from the engine
block.

If Your Engine Overheats

The pointer of your vehicle's temperature gauge should stay in
the midrange under most conditions.
It may go higher if you are driving up
a long steep hill on a very hot day. If
it climbs to the red mark, you should
determine the reason.

Driving with the temperature gauge
pointer at the red mark can cause serious damage to your engine.
Your vehicle can overheat for several
reasons, such as lack of coolant or a

mechanical problem. The only

indication may be the temperature

gauge climbing to or above the red mark. Or you may see steam or
spray coming from under the hood.

In either case, you should take

immediate action.
1. Safely pull to the side of the road.
Put the transmission in Neutral or
Park and set the parking brake.
Turn off the heating and cooling system and all other accessories.
Turn on the hazard warning indicators.
2. If you see steam and/or spray coming from under the hood, turn
off the engine.
3. If you do not see steam or spray, leave the engine running and
watch the temperature gauge. If the high heat is due to overloading (climbing a long, steep hill on a
hot day with the A/C running, for example), the engine should start
to cool down almost immediately. If it does, wait until the tempera-
ture gauge comes down to the mid-
point then continue driving.

Taking Care of the Unexpected

NOTICE

Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.ProCarManuals.comMain Menu Table of Contents s t

If Your Engine Overheats
4. If the temperature gauge stays at the red mark, turn off the engine.
5. Wait until you see no more signs of steam or spray, then open the

hood.

6. Look for any obvious coolant leaks, such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you find a leak, it
must be repaired before you
continue driving (see Towing on
page 244).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page 132). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks.
8. If there was no coolant in the reserve tank, you may also have to
add coolant to the radiator. Let the
engine cool down until the pointer reaches the middle of the tempera-
ture gauge, or lower, before check- ing the radiator.
9. Using gloves or a large heavy cloth, turn the radiator cap
counterclockwise, without pushingdown, to the first stop. This
releases any remaining pressure in
the cooling system. After the
pressure releases, push down on
the cap and turn it until it comes
off.
10.Start the engine and set the
temperature control lever tomaximum. Add coolant to the
radiator up to the base of the filler
neck. If you do not have the
proper coolant mixture available,
you can add plain water. Remember to have the cooling
system drained and refilled with
the proper mixture as soon as you
can.

11. Put the radiator cap back on tightly. Run the engine and watch
the temperature gauge. If it goes
back to the red mark, the engine
needs repair. (See Towing on
page 244.)
12.If the temperature stays normal, check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the MAX mark. Put the cap back on

tightly.
Taking Care of the Unexpected

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.ProCarManuals.comMain Menu Table of Contents s t
