Hatch/Trunk
CAUTION:
It can be dangerous to drive with the hatch/trunk
lid open because carbon monoxide (CO) gas can
come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even death.
If you must drive with the hatch/trunk lid open
or if electrical wiring or other cable connections
must pass through the seal between the body
and the hatch/trunk lid:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on Bi
-Level or Vent with the outside air
button pressed. That will force outside air
into your vehicle. See ªComfort Controlsº
in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
NOTICE:
If you put things in the hatch/trunk area, be sure
they won't break the glass when you close it.
Never slam the hatch/trunk lid down. You could
break the glass or damage the defogger grid.
When you close the hatch/trunk lid, make sure
you pull down from the center, not the sides.
If you pull the hatch/trunk lid down from the
side too often, the weatherstrip can be damaged.
NOTICE:
Do not store heavy or sharp objects in the
rear storage compartments located in the
hatch/trunk area. If you do, the objects could
damage the underbody.

2-60
Convenience Net (Option)
Your vehicle may have a convenience net. You will see
it on the back wall of the rear area of the vehicle.
Put small loads, like grocery bags, in the net. It can help
keep them from falling over during sharp turns or quick
starts and stops. The convenience net is not for larger,
heavier loads.
You can unhook the net and place it in one of the
rear storage compartments when you are not using it.
On coupe models only, a vinyl storage bag has also
been provided.
Ashtray and Cigarette Lighter
The ashtray and cigarette lighter are located on the
instrument panel, in front of the shift lever. To use the
ashtray, lift up on the bottom of the door.
NOTICE:
Don't put papers and other things that burn
into the ashtray. If you do, cigarettes or other
smoking materials could set them on fire,
causing damage.
Loose objects (such as paper clips) can lodge behind
and beneath the ashtray lid and prevent movement of
the lid. You should avoid putting small, loose objects
near the ashtray.
To use the cigarette lighter, push it in all the way and
let go. When it's ready, it will pop back out by itself.
NOTICE:
Don't hold a cigarette lighter in with your hand
while it is heating. If you do, it won't be able to
back away from the heating element when it's
ready. That can make it overheat, damaging the
lighter and the heating element.
Sun Visors
To block out glare, you can swing down the visors.
You can also swing them to the side.
Lighted Visor Vanity Mirrors
Pull down the sun visor and lift the cover to expose the
lighted vanity mirror. When the cover is lifted, the lamps
will come on automatically, even if the ignition is off.

2-87 Engine Coolant Temperature Gage
United States Canada
This gage shows the engine coolant temperature. If the
gage pointer moves into the shaded area, your engine
is too hot.
This means that your engine coolant has overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn off the engine as soon as possible.
(The larger tic marks are in increments of 30
below
220
F (104
C) and in increments of 10
above
220
F (104
C).)
See ªEngine Overheatingº in the Index for
more information.
Malfunction Indicator Lamp
(Check Engine Light)
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (On
-Board
Diagnostics
-Second Generation) and is intended
to assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. The CHECK ENGINE light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent
more serious damage to your vehicle. This system
is also designed to assist your service technician in
correctly diagnosing any malfunction.
