last
two bars, the message RESERVE

Here are threethings that some owners
ask about. None of these show a
problem with your bel gage:
At. the gas station, the gas pump shuts
.off be€ore the gage reads F (Full).
It takes a little more or. less fu.el to fill
up than the gage indicated. For
.example., the gage may have. indicated

Run your engbe only as. long -as you
must. This saves fuel. When you run the
engine,
make it go a little faster than
just idle. That is, push the accelerator
slightly. This uses less fuel for the heat
that you get and it keeps the battery
charged. You will need a well-charged
battery
to restart the vehicle, and
possibly €or signaling later on with your
headlights. Let the
heater mn €or a
while.
Then> shut the engine off and close the
window almost all the way to preserve
the heat. Start the engine again and
repeat this only when you feel really
qncomfortable
from the cold. But do it
as little as possible. Preserve the fuel as
long as you can. To help keep warm,
you can get out of the vehicle and do
some fairly vigorous exercises every
haK-hour or so until help comes.
If You're Stuck in Deep Snow
You should twn your ASR system off if
you're stuck in deep snow. See the
Index under Accelerafion Slip
Regulation (ASR) Sysleem. This manual
explains how to get the vehicle out
of
deep snow without damaging it. See the
Index under Rocking Your Vehicle.
Towing a Trailer
Your Corvette is neither designed nor
intended to tow a trailer.
