when your vehicle was new. If you
regularly carry heavy items in the
trunk or pull a trailer, readjustment
may be required. Adjustments
should be done by your dealer or
another qualif ied technician.The low beam headlight bulbs are
high voltage discharge tube bulbs.
High voltage can remain in the
circuit even with the light switch of f
and the key removed. Because of
this, you should not attempt to
examine or change a low beam
headlight bulb yourself . If a low
beam headlight bulb fails, take the
vehicle to your dealer to have it
replaced.Your vehicle has halogen headlight
bulbs. When replacing a bulb, handle
it by its base, and protect the glass
f rom contact with your skin or hard
objects. If you touch the glass, clean
it with denatured alcohol and a clean
cloth.

If possible, periodically run the
engine until it reaches f ull
operating temperature (the
cooling f ans cycle on and of f
twice). Pref erably, do this once a
month. Support the f ront wiper blade
arms with a f olded towel or rag so
they do not touch the windshield.
To minimize sticking, apply a
silicone spray lubricant to all door
and trunk seals. Also, apply a
vehiclebodywaxtothepainted
surfaces that mate with the door
and trunk seals.
Cover the vehicle with a
‘‘breathable’’ cover, one made
f rom a porous material such as
cotton. Non-porous materials, such
as plastic sheeting, trap moisture,
which can damage the paint.
Leave the parking brake off. Put
the transmission in reverse
(manual) or Park (automatic).
Block the rear wheels.
If the vehicle is to be stored f or a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Leave one window open slightly (if
the vehicle is being stored
indoors).

When you turn the ignition switch to
the START (III) position, you do not
hear the normal noise of the engine
trying to start. You may hear a
clicking sound, a series of clicks, or
nothing at all.
Diagnosing why the engine won’t
start f alls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position:
Check these things:
Turn the ignition switch to the ON
(II) position. Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See on page .
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 the
START (III) position. If the
headlights do not dim, check the
condition of the f uses. If the f uses
areOK,thereisprobably
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 .
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. You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly.
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 connections (see page ).
You can then try jump starting the
vehicle from a booster battery (see
page ).
