Engine Oil
5. Put a new washer on the drain bolt,
then reinstall the drain bolt.
Tighten it to:
33 lbf.ft (45 N·m, 4.6 kgf·m)
6. Refill the engine with the recom­
mended
oil.
Engine oil change capacity
(including filter):
5.1 US qt (4.8 Q, 4.2 Imp qt)
7. Install the engine oil fill cap. Start
the engine. The oil pressure
indicator light should go out within
five seconds. If it does not, turn off
the engine and reinspect your
work.
8. Let the engine run for several
minutes and check the drain bolt
and
oil filter for leaks.
160 Maintenance
9. Turn off the engine, let it sit for
several minutes, then check the
oil
level. If necessary, add oil to bring
the level to the upper mark on the
dipstick.
NOTICE
Improper disposal of engine oil can be
harmful
to the environment. If you
change your own oil, please dispose
of
the used oil properly. Put it in a sealed
container and take it
to a recycling
center. Do not discard it
in a trash bin
or dump it on the ground.

Air Conditioning System
Your car's air conditioning is a sealed
system. Any major maintenance,
such as recharging, should
be done
by a qualified mechanic. You can do
a couple of things to
make sure the
air conditioning works efficiently.
Periodically
check the engine's
radiator and air conditioning
condenser for leaves, insects, and
dirt
stuck to the front surface. These
block the air flow and reduce cooling
efficiency.
Use a light spray from a
hose or a soft
brush to remove them.
NOTICE
The condenser and radiator fins bend
easily. Only use a low-pressure
~pray
or soft-bristle brush to clean them.
182 Maintenance
Run the air conditioning at least once
a
week during the cold weather
months. Run it for at least ten
minutes while you are driving at a
steady speed with
the engine at
normal operating temperature. This
circulates the lubricating oil con­
tained in
the refrigerant.
If the air conditioning does not get as
cold
as before, have your dealer
check the system. Recharge the
system with Refrigerant HFC-134a
(R-134a). (See Specifications on page
245.)
NOTICE
Whenever you have the air conditioning
system serviced, make sure the service
facility uses a refrigerant recycling
system. This system captures the
refrigerant
for reuse. Releasing
refrigerant into the atmosphere can
damage the environment.

If Your Engine Won't Start
Diagnosing why your engine won't
start falls into two areas, depending
on what you
hear when you press
the ENGINE START button.
• You hear nothing, or almost
nothing.
The engine's starter
motor does not operate at
all, or
operates 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.
218 Taking Care of the Unexpected
Nothing Happens or the Starter
Motor Operates Very Slowly
When you press the ENGINE
START button, you do not hear the
normal noise of the engine trying to
start. You may hear a clicking sound
or series of clicks, or nothing at
all.
Check these things:
• Your car has the Immobilizer
System.
You should use a
properly-coded master or valet key
to start the engine (see page 59).
A key that
is not properly coded
will cause the immobilizer system
indicator
in the dash panel to blink
rapidly.
• Turn the ignition switch to ON (II).
Turn on the headlights and check
their brightness.
If the headlights
are very dim or don't light at
all,
the battery is discharged. See
Jump Starting on page 220.
• Press
the ENGINE START button,
then release
it. If the headlights do
not dim, check the condition of the
fuses.
If the fuses are 0 K, there is
probably something wrong with
the electrical circuit for the
ignition switch
or starter motor.
You
will need a qualified
technician to determine the
problem.
(See Emergency
Towing on page 238 .)

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 connections
(see page 177). You can then try
jump starting the car from a booster
battery (see page 220).
The Starter Operates Normally
In this case, the starter motor's
speed sounds normal, or even faster
than normal, when you press the
ENGINE START button, but the
engine does not run.
• Are you using the proper starting
procedure? Refer to
Starting the
Engine on page 131 .
• Do you have fuel? Turn the
ignition switch to
ON (ID 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.
If Your Engine Won't Start
• There may be an electrical
problem, such as
no power to the
fuel pump.
Check all the fuses
(see page
231 ) .
If you find nothing wrong, you will
need a qualified technician to find
the problem. See
Emergency
Towing on page 238.
Taking Care of the Unexpected 219

Jump Starting
If your car's battery has run down,
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.
220 Taking Care of the Unexpected
A battery can explode if you do
not
follow the correct procedure,
seriously injuring anyone
nearby.
Keep
all sparks, open flames,
and smoking materials away
from the battery.
To jump start your car, follow these
directions closely:
1. Open the hood and check the
physical condition of the battery
(see page 177 ) . 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.
NOTICE
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
and
set the parking brake.

Low Oil Pressure Indicator
This indicator should light when the
ignition switch is ON (II), and go out
after
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 pressure
and serious engine damage is
possible. In either case, you should
take immediate action.
226 Taking Care of the Unexpected
NOTICE
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 car
stopped.
1. Safely pull off the road and shut
off the engine. Turn on the hazard
warning indicators.
2. Let the car sit for a minute. Open
the hood and check the oil level
(see page 119 ). 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 the
dipstick (see page 120 ) .
4. Start the engine and watch the oil
pressure indicator.
If the light
does 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 Emergency
Towing on page 238 .)

The Brake System Indicator light
comes on when you turn the ignition
ON (II). If the parking brake is not
set, 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 car'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
170 ) . If the
fluid level is
low, take the car 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 car
begins to slow down, and you
will
have to press harder on the pedal.
The distance needed to stop will be
much longer.
Brake System Indicator
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 car.
You
should have it towed, and repaired as
soon as possible.
If you must drive the car a short
distance in this condition, drive
slowly and cautiously.
