Changing a Flat Tire, If Your Engine Won't Start
19. Secure the flat tire by screwing the win

g bolt back into its hole.
20. Store the jack in its holder. Turn the jack's end bracket to lock it in
place.

Replace the cover. Store the
tool kit. 21. Stor
e the center cap in the trunk.
Make

sure it does not get scratch-
ed

or damaged.
22.
Lower the trunk floor, then close
the trunk lid.
Type SH only
If yo

u mount the compact spare on
either front or rear tire, it may cause
the

ATTS indicator light in the
instrument

panel to come on due to
the

difference in tire diameter. The
light

will go out when the proper tire

is installed.
If Your Engine Won't Start
Diagnosing

why your engine won't
start falls into two areas, depending
on what you hear when you turn the
key to START (III):
You hear nothing, or almostnothing. The engine's starter
motor does not operate at all, oroperates

very slowly. You can hear the starter motor
operating normally, or the starter
motor
sounds like it is spinning
faster than normal, but the engine does

not start up and run.

If Your Engine Won't Start

Nothing Happens or the Starter
Motor Operates Very Slowly
When you turn the ignition switch to START (III), you do not hear the
normal noise of the engine trying tostart. You may hear a clicking sound
or series of clicks, or nothing at all. Check these things: Your vehicle has the Immobilizer
System. You should use a
properly-coded master or valet key
to start the engine (see page 69).
A key that is not properly coded will cause the immobilizer systemindicator in the dash panel to blinkrapidly. Check the transmission interlock.
If you have a manual transmission,
the clutch pedal must be pushed all the way to the floor or the
starter will not operate. With an
automatic transmission, it must be
in Park or Neutral. Turn the ignition switch to ON (II).
Turn on the headlights and check
their brightness. If the headlightsare very dim or don't light at all,
the battery is discharged. See

Jump Starting on page 236.
Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the fuses. If
the fuses are OK, there is proba-
bly something wrong with the electrical circuit for the ignitionswitch or starter motor. You will
need a qualified technician to
determine the problem. (See
Towing on page 250.) If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is dis-
charged or the connections are
corroded. Check the condition of
the battery and terminal connec- tions (see page 190). You can
then try jump starting the vehicle
from a booster battery (see page
236).

If Your Engine Won't Start, Jump Starting

The Starter Operates Normally In this case, the starter motor'sspeed sounds normal, or even faster
than normal, when you turn the
ignition switch to START (III), but
the engine does not run. Are you using the proper starting
procedure? Refer to Starting the
Engine on page 133.
Do you have fuel? Turn the
ignition switch to ON (II) for a
minute and watch the fuel gauge.
The low fuel level warning light
may not be working, so you were
not reminded to fill the tank.
There may be an electrical
problem, such as no power to the
fuel pump. Check all the fuses

(see page 245).

If you find nothing wrong, you will

need a qualified technician to find

the problem. See Towing on page
250. Jump Starting
If your vehicle's battery has rundown, you may be able to start the
engine by using a booster battery.
Although this seems like a simple procedure, you should take several

precautions.

You cannot start a Honda with an automatic transmission by pushing
or pulling it. To jump start your vehicle, follow
these directions closely:
1. Open the hood and check the physical condition of the battery(see page 190). In very cold
weather, check the condition of
the electrolyte. If it seems slushy or like ice, do not try jump starting
until it thaws.

If a battery sits in extreme cold, the
electrolyte inside can freeze.

Attempting to jump start with a frozen
battery can cause it to rupture.

2. Turn off all the electrical acces- sories: heater, A/C, stereo system,
lights, etc.
Put the transmission in Neutral or
Park and set the parking brake.

3. Connect one jumper cable to the positive ( + ) terminal on the
booster battery. Connect the other
end to the positive ( + ) terminal
on your Honda's battery. 4. Connect the second jumper cable
to the negative (—) terminal on
the booster battery. Connect theother end to the grounding strap
as shown. Do not connect this
jumper cable to any other part of
the engine.
5. If the booster battery is in another vehicle, have an assistant startthat vehicle and run it at a fast idle.
BOOSTER BATTERY

6. Start your vehicle. If the starter motor still operates slowly, check
the jumper cable connections to make sure they have good metal-
to-metal contact.
7. Once your vehicle is running, disconnect the negative cable from
yourvehicle, then from the booster battery. Disconnect the
positive cable from your vehicle,
then the booster battery.

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 shoulddetermine 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 orspray 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, turnoff 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.
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.

If Your Engine Overheats

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 250).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page 124). 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 comesoff. 10. Start the engine and set the
temperature control lever to
maximum. 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 250.)
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

Low Oil Pressure Indicator

This indicator should light when the
ignition switch is ON (II), and go outafter the engine starts. It should
never come on when the engine is
running. If it starts flashing, it indicates that the oil pressure
dropped very low for a moment, then
recovered. If the indicator stays on
with the engine running, it shows that the engine has lost oil pressureand serious engine damage is
possible. In either case, you should
take immediate action.
Running the engine with low oil
pressure can cause serious mechanical damage almost immediately. Turn off
the engine as soon as you can safely get
the vehicle stopped.

1. Safely pull off the road and shut off the engine. Turn on the hazard
warning indicators.
2. Let the vehicle sit for a minute. Open the hood and check the oil
level (see page 123). Although oil
level and oil pressure are not directly connected, an engine that
is very low on oil can lose pressure
during cornering and other driving

maneuvers.

3. If necessary, add oil to bring the level back to the full mark on thedipstick (see page 173). 4. Start the engine and watch the oil
pressure indicator. If the lightdoes not go out within ten seconds,
turn off the engine. There is a
mechanical problem that needs to
be repaired before you can continue driving. (See Towing on

page 250.)

Charging System Indicator

CHARGING SYSTEM INDICATOR
This indicator should come on when the ignition switch is ON (II), and goout after the engine starts. If it
comes on brightly when the engine
is running, it indicates that the
charging system has stopped
charging the battery. Immediately turn off all electrical
accessories: radio, heater, A/C, rear
defogger, cruise control, etc. Try not
to use other electrically-operated controls such as the power windows.
Keep the engine running and take
extra care not to stall it. Starting the
engine will discharge the battery
rapidly. By eliminating as much of the
electrical load as possible, you can
drive several miles (kilometers)
before the battery is too discharged to keep the engine running. Drive to
a service station or garage where
you can get technical assistance.

Malfunction Indicator Lamp

This indicator comes on for a few seconds when yon turn the ignition
switch ON (II). If it comes on at any
other time, it indicates one of the
engine's emissions control systems
may have a problem. Even though
you may feel no difference in your
vehicle's performance, it can reduce
your fuel economy and cause your
vehicle to put out excessive emissions. Continued operation may
cause serious damage. If you have recently refueled your
vehicle, the cause of this indicator coming on could be a loose or
missing fuel fill cap. Check the cap
and tighten it until it clicks. Replace
the fuel fill cap if it is missing.
Tightening the cap will not make the indicator turn off immediately; it
takes three driving trips.
If the indicator remains on past threedriving trips, or the fuel cap was not
loose or missing, have the vehicle
checked by the dealer as soon as
possible. Drive moderately until the dealer has inspected the problem.
Avoid full-throttle acceleration and driving at high speed.
You should also have the dealer inspect your vehicle if this indicator
comes on repeatedly, even though it
may turn off as you continue driving.If you keep driving with the
malfunction indicator lamp on, you can
damage your vehicle's emissionscontrols and engine. Those repairs may
not be covered by your vehicle 's warranties.

Brake System Indicator

The Brake System indicator light comes on when you turn the ignitionON (II). If the parking brake is notset, it goes off after you start the
engine. If the parking brake is set, it
goes off when you fully release the
parking brake with the engine
running.
If it comes on at any other time, it
indicates a problem with the vehicle's
brake system. In most cases, the problem is a low fluid level in the brake fluid reservoir. Press lightly on
the brake pedal to see if it feels
normal. If it does, check the brake
fluid level the next time you stop at a service station (see page 185). If the
fluid level is low, take the vehicle to
your dealer and have the brake system inspected for leaks or worn
brake pads.
However, if the brake pedal does not
feel normal, you should take
immediate action. Because of the
brake system's dual-circuit design, a
problem in one part of the system
will still give you braking at two
wheels. You will feel the brake pedal go down much farther before the
vehicle begins to slow down, and you will have to press harder on thepedal. The distance needed to stop
will be much longer.
Slow down by shifting to a lower
gear, and pull to the side of the road
when it is safe. Because of the longer distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed, and repaired as

soon as possible.

If you must drive the vehicle a short
distance in this condition, drive
slowly and cautiously.
