This light will come on briefly when
you turn on
the ignition, but the engine
is not running, as a check to show you it
is working. Then it should go out when
the engine starts. If it stays on, or

may
have a problem with the electrical
charging system. It could indicate that
you have a loose generator drive belt, or
another electrical problem. Have
it
checked right away. Driving while this
light
is on could drain your battery.
If you must drive a short distance with
the light
on, be certain to turn off
all your accessories, such as the radio

rmw-rirmuflh Ventilation System
Your Geo's flow-through ventilation
system supplies outside air into the
vehicle when it is moving. Outside air
will
also enter the car when the heater
or the air conditioning fan is running.
Ventilation Tips
Keep the hood and front air inlet free
of ice, snow, or any other obstruction
(such as leaves). The heater and
defroster will work far better,
reducing the chance of fogging the
inside of your windows.
When you enter a car in cold weather,
move the fan lever toward
# for a
few moments before driving off. This
helps clear the intake ducts of snow
and moisture, and reduces 'the chance
of fogging the inside of your
windows.
Keep the air path under the front seats
clear of objects. This helps air to
circulate throughout your car.
H Audio Systems
Your Delco@ audio system has been
designed to operate easily and give years
of listening pleasure. But you will get
the most enjoyment out of it if you
acquaint yourself with it first. Find out
what your Delco@ audio system can do

sure you're getting the most out of the
advanced engineering that went into it.

drive slower for about ten minutes. If
the warning doesn’t come back on, you
can drive normally.
If the warning continues, pull over,
stop, and park your vehicle right away.
If there’s still no sign of steam, you can
idle the engine for two
or three minutes
while you’re parked, to see if the
warning stops. But then, if you still have
the warning, TURN OFF THE
ENGINE AND GET EVERYONE OUT

system is set for the proper coolant

wrong mix, your engine could get
too hot but you wouldn’t get the
overheat warning. Your engine
