2001 HONDA ACCORD SEDAN engine overheat

5-speed Manual Transmission
The manual transmission is syn- chronized in all forward gears for
smooth operation. It has a lockout so
you cannot shift directly from Fifth to Reverse. When shifting up or down, make sure you push the clutch
pedal down all the way, shift to the
next gear, and let the pedal up
gradually. When you are not shifting, do not rest your foot on the clutch
pedal. This can cause your clutch to
wear out faster. Come to a full stop before you shift
into Reverse. You can damage the
transmission by trying to shift into Reverse with the car moving. Push
down the clutch pedal, and pause fora few seconds before shifting into
Reverse, or shift into one of the
forward gears for a moment. This stops the gears so they won't "grind."
When slowing down, you can get extra braking from the engine byshifting to a lower gear. This extra
braking can help you maintain a safe speed and prevent your brakes from
overheating while going down a
steep hill. Before downshifting,
make sure engine speed will not go into the tachometer's red zone in the
lower gear.

Driving

Rapid slowing or speeding-up

can cause loss of control on
slippery surfaces. If you crash,

you can be injured.

Use extra care when driving on

slippery surfaces.

Traction Control System

TCS ON/OFF Switch

This switch is under the side vent. It lets you turn the Traction ControlSystem on and off. You cannot turn
off the TCS while the TCS indicator
light is flashing. Deactivate the system by pressing
the TCS On/Off switch. The TCS
indicator light comes on as a
reminder. Pressing the switch again
turns the system back on.
The Traction Control System turns on every time you start the engine,
even if you turned it off the last time
you drove the vehicle. TCS Indicator
The TCS indicator comes on orflashes under the following condi-tions:
When you turn the ignition switch
to ON (II).
When you manually turn off the

TCS.
It flashes when the TCS is

regulating wheelspin.

If the system's diagnostics senses
a problem in the TCS, the indica-
tor will come on and stay on.
If the brakes overheat, the
indicator will come on.

Towing a Trailer

Driving Safely With a Trailer
The added weight, length, and height of a trailer will affect your
vehicle's handling and performance, so driving with a trailer requiressome special driving skills and

techniques.

For your safety and the safety ofothers, take time to practice driving
maneuvers before heading for theopen road, and follow the guidelines
discussed below.

Towing Speeds and Gears

Drive slower than normal in all
driving situations, and obey posted
speed limits for vehicles with trailers.
If you have an automatic
transmission, use D4 position when
towing a trailer on level roads. D3 is
the proper shift lever position to use
when towing a trailer in hilly terrain. (See "Driving on Hills" in the next
column for additional gear
information.)
Making Turns and Braking

Make turns more slowly and wider
than normal. The trailer tracks a smaller arc than your vehicle, and it
can hit or run over something the
vehicle misses. Allow more time and distance for braking. Do not brake or
turn suddenly as this could cause the
trailer to jackknife or turn over.

Driving on Hills

When climbing hills, closely watch your temperature gauge. If it nearsthe red (Hot) mark, turn the airconditioning off, reduce speed and, if
necessary, pull to the side of the
road to let the engine cool.
If the automatic transmission shifts
frequently between 3rd and 4th
gears while going up a hill, shift to
D3.
If you must stop when facing uphill,
use the foot brake or parking brake.
Do not try to hold the vehicle in
place by pressing on the accelerator, as this can cause the automatic
transmission to overheat.
When driving down hills, reduce your speed and shift down to 2nd
gear. Do not "ride" the brakes, andremember it will take longer to slowdown and stop when towing a trailer.

4. Put the new spark plug into the socket; then screw it into the hole.
Screw it in by hand so you do not
crossthread it.
5. Torque the spark plug. (If you do
not have a torque wrench, tighten
the spark plug two-thirds of a turn after it contacts the cylinder head.)

Taking Care of the Unexpected

If Your Engine Overheats
The pointer of your car's tempera- ture gauge should stay in the mid-range 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 car 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

Steam and spray from an
overheated engine can

seriously scald you.

Do not open the hood if steam

is coming out.

NOTICE

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 Emergency
Towing on page 320).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page 184). 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 pushing
down, 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 dial tomaximum (climate control to
FULL AUTO at 90°F/32°C). 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 Emergency
Towing on page 320.)
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.
