Ventilation Tips
0
0
0
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 vehicle in cold
weather, move the fan lever towards
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 vehicle.
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@ system can do and how to operate
all its controls, to be sure you’re getting
the most out of the advanced engineering
that went into
it.
NOTICE:
Before you add any sound equipment
to your vehicle - like a tape player,
CB radio, mobile telephone or
two-way radio
- be sure you can
add what you want.
If you can, it’s
very important to do it properly.
Added sound equipment may inter-
fere
with the operation of your
vehicle’s engine, Delco8 radio or
other systems, and even damage
them. And, your vehicle’s systems
may interfere with the operation of
sound equipment that has been added
improperly.
So, before adding sound equipment,
check with your dealer and be sure
to
check Federal rules covering mobile
radio and telephone units.
