Dirt build-up in the loops of the seat
belt anchors can cause the belts to
retract slowly. Wipe the insides of
the loops with a clean cloth
dampened in mild soap and warm
water or isopropyl alcohol.Clean the windows, inside and out,
with a commercially-available glass
cleaner. You can also use a mixture
of one part white vinegar to ten parts
water. This will remove the haze that
builds up on the inside of the
windows. Use a sof t cloth or paper
towels to clean all glass and clear
plastic surf aces.If you want to use an air f reshener/
deodorizer in the interior of your car,
it is best to use a solid type. Some
liquid air f resheners contain chemi-
cals that may cause parts of the
interior trim and f abric to crack or
discolor.
If youusealiquidairfreshener,
make sure you f asten it securely so it
does not spill as you drive.

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.
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 .
Store the tools and the jack in the
tool tray, and place the tool tray
back in the trunk.
Store the wheel cover or center
cap in the trunk. Make sure it does
not get scratched or damaged.
Lower the trunk f loor, then close
the trunk lid.
