Oldsmobile 2003 Silhouette Owner's Manual page 292

Here are some things to do to summon help and keep
yourself and your passengers safe:
e
Turn on your hazard flashers.
Tie a red cloth to your vehicle to alert police that
you've been stopped by the snow.
e
Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make
body insulators from newspapers, burlap bags, rags,
floor mats
-
anything you can wrap around
yourself or tuck under your clothing to keep warm.
. , . - .
.
.
You can run the engine to keep warm, but be careful.
Snow can trap exhaust gases u n , , r your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You can't see it
or smell it, so you might not know it is in
your vehicle. Clear away snow from around
the base of your vehicle, especially any that
is blocking your exhaust pipe. And check
around again from time to time to be sure
snow doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will
help keep CO out.
