The car can easily roll off the
jack, seriously injuring anyone
underneath.
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):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. 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:
Check the transmission interlock.
The transmission must be in Park
orNeutralorthestarterwillnot
operate. 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.
Store the jack in its holder. Turn
the jack’s end bracket to lock it in
place. Replace the cover. Store the
tools.
Store the center cap in the trunk.
Make sure it does not get scratch-
ed or damaged.
Unhook the handle f rom the trunk
opening and lower the f loor lid.
Close the trunk lid.

seriously injure the occupants.
Store the wheel, jack and tools
securely before driving.

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. Seeon page .
Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the f uses. If
thefusesareOK,thereisproba-
bly something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualif ied technician to
determine the problem. (See 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
(see page ).
If youfindnothingwrong,youwill
need a qualif ied technician to f ind
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. Are you using the proper starting
procedure? Ref er to on page .
