Plugging the cord into an ungrounded outlet could cause an electrical
shock.
Also, the wrong kind of extension cord could overheat and
cause a fire. You could be seriously injured. Plug the cord into a
properly grounded three-prong

How long should you keep the block heater plugged in? The answer ,)ends
on the weather, the kind
of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact a GM dealer in the
area where you'll be parking your vehicle. The dealer can give\

The charging system light will come on briefly when you turn \
the ignition on,
but the engine is not running. As a check to show you the light is working.
Then it should go out once the engine is running.
If it stays on, or comes on
while you are driving,
you may have a problem with the electrical charging
system.
It could indicate that you have a loose accessory drive belt, or
another electrical problem. Have
it checked right away. Driving while this light
is on could drain your battery.
The charging system light is
on the left bottom corner of your standard
cluster. It is part
of the digital cluster voltmeter.
If you must drive a short distance with the light on, be certain to turn off all
your accessories, such as the radio and heater/air conditioner. \

Flow-Through Ventilation System
K3302
Your vehicle's flow-through ventilation system supplies outside air to\
the inside
of your vehicle when it is moving. With the side windows closed, air will flow
into the front air inlet grilles at the base
of the windshield, through the vehicle
and out the rear air exhaust valves. Outside air will also en\
ter the vehicle
when the heater or the air conditioning fan is running.
Venfilation Tips
Keep the hood and front air inlet free of ice, snow, or any \
other
obstruction (such as leaves). The heater and defroster will w\
ork far better, reducing the chance of fogging the inside
of your windows.
When you enter a vehicle in cold weather, turn the blower fan\
to HIGH
for a few moments before driving
off. This helps clear the intake ducts
of snow and moisture, and reduces the chance of fogging the i\
nside of
your windows.
Keep the air path under the front seats clear of objects. Thi\
s helps air
to circulate throughout your vehicle.
