Engine Exhaust
CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can't see or
smell. It can cause unconsciousness and death.
You might have exhaust coming in if:

Your exhaust system sounds strange
or different.

Your vehicle gets rusty underneath.

Your vehicle was damaged in a collision.

Your vehicle was damaged when driving over
high points on the road or over road debris.

Repairs weren't done correctly.

Your vehicle or exhaust system had been
modified improperly.
If you ever suspect exhaust is coming into
your vehicle:

Drive it only with all the windows down to
blow out any CO; and

Have your vehicle fixed immediately.
Running Your Engine While
You're Parked
It's better not to park with the engine running. But if you
ever have to, here are some things to know.
CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle (see the earlier Caution under
ªEngine Exhaustº).
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the fan switch is at the highest setting. One place
this can happen is a garage. Exhaust
-- with
CO
-- can come in easily. NEVER park in a
garage with the engine running.
Another closed-in place can be a blizzard.
(See ªBlizzardº in the Index.)

2-54 Rear Storage Armrest (If Equipped)
Your vehicle may be equipped with a rear seat armrest
which includes an open storage compartment and a dual
cupholder that unfolds for use. To open, lift the front
edge. (This feature is available on vehicles with leather
interiors only.)
Convenience Net
The convenience net is located inside the back wall of
the trunk. Put small loads, like grocery bags, behind the
net. It can help keep them from falling over during sharp
turns or quick starts and stops.
The net is not for larger, heavier loads. Store them in the
trunk as far forward as you can. When not using the net,
hook the net to the tabs securing it to the sill plate.
Ashtrays and Cigarette Lighter
NOTICE:
Don't put papers or other flammable items
into your ashtrays. Hot cigarettes or other
smoking materials could ignite them, causing a
damaging fire.
Front Ashtray
With the full center console (available on DeVille
Concours only), the ashtray is located below the climate
control system. To open, press on the lower edge of the
cover. To clean the ashtray, lift it out by gripping the
sides. For vehicles without the center console, pull the
tray out to reveal the ashtray. The tray is located beneath
the radio. To clean this ashtray, lift it out by pulling on
the snuffer.
