battery cables bef ore connecting the
battery to a charger.

If you have a f lat tire while driving,
stop in a saf e place to change it.
Stopping in traf f ic or on the shoulder
of a busy road is dangerous. Drive
slowly along the shoulder until you

Follow the directions for
changing a tire exactly, and
never get under the car when it
is supported only by the jack.

Diagnosing why your engine won’t
start f alls into two areas, depending
on what you hear when you turn the
key to START (III):When you turn the ignition switch to
START (III), 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:
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
f aster than normal, but the engine
does not start up and run. Check the transmission interlock.
If you have a manual transmission,
the clutch pedal must be pushed
all the way to the f loor 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 headlights
are very dim or don’t light at all,
the battery is discharged. See
on page . Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the f uses. If
the f uses are OK, there is proba-
bly something wrong with the
electrical circuit f or the ignition
switch or starter motor. You will
need a qualif ied technician to
determine the problem. (See
on page .)
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 ). You can
then try jump starting the car from
a booster battery (see page ).

In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to START (III), but
the engine does not run.
Your car has the Immobilizer
System. You should use a
properly-coded master or valet key
to start the engine (see page ).
A key that is not properly coded
will cause the immobilizer system
indicator in the dash panel to blink
rapidly.
Are you using the proper starting
procedure? Ref er to on page . Do you have f uel? Turn the
ignition switch to ON (II) for a
minute and watch the f uel gauge.
The low f uel level warning light
may not be working, so you were
not reminded to f ill the tank.
There may be an electrical
problem, such as no power to the
f uel pump. Check all the f uses

Keep the ends of the jumper cables
away from each other and any metal
on the car until all are disconnected.
Otherwise, you may cause an
electrical short.Once your car is running, discon-

car, then from the booster battery.
Disconnect the positive cable f rom
your car, then the booster battery. Start your car. If the starter motor
still operates slowly, check the
jumper cable connections to make
sure they have good metal-to-
metal contact.

This indicator should light when the
ignition switch is ON (II), and go out
af ter the engine starts. It should
never come on when the engine is
running. If it starts f lashing, it
indicates that the oil pressure
dropped very low f or 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.Saf ely pull of f the road and shut
of f the engine. Turn on the hazard
warning indicators.
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ). Letthecarsitforaminute.Open
the hood and check the oil level
(see page ). 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.Start the engine and watch the oil
pressure indicator. If the light
does not go out within ten seconds,
turn of f the engine. There is a
mechanical problem that needs to
be repaired bef ore you can
continue driving. (See
on page .)
The engine running generates the oil
pressure. When the Auto Idle Stop is
activated, the engine is stopped, the
oil pressure is dropped, and the low
oil pressure indicator does not light.
