stops), wait
15 seconds and start over.
When the engine starts, let go
of the key and the
accelerator pedal.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle.
If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer.
If you don’t,
your engine might not perform properly.
If you ever have to have your vehicle towed, see
the part of this manual that tells how to do it
without damaging your vehicle. See “Towing
Your Vehicle” in the Index.
Fuel Regulator
You have a fuel regulator that shuts the fuel off when
the engine reaches 5,600 rpm.
Engine Coolant Heater (Option)
In very cold weather,
0°F (-18°C) or colder,
the engine coolant heater
can help. You’ll get easier
starting and better fuel
economy during engine
warm-up. Usually, the
coolant heater should be
plugged in a minimum
of
four hours prior to starting
your vehicle.
To Use the Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 1 10-volt AC outlet.
2-18

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
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 110-volt
AC outlet. If the cord won’t reach, use
a heavy-duty three-prong extension cord rated
for at least
15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before
to keep it away
from moving engine parts. If
you don’t, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of
trying to list everything here, we ask that you contact
your
GM dealer in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.
Automatic Transmission Operation
There are several different positions for your shift lever.
PARK
(P): This locks your rear wheels. It’s the best
position to use when you start your engine because your
vehicle can’t move easily.
I A CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in
PARK (P) with the
parking brake firmly set. Your vehicle can roll.
CAUTION: (Continued)

the knob clockwise for warmer air. Move the knob
counterclockwise
for cooler air.

Rear Heating System (Option)
You may have the optional rear heater. The three-speed
fan switch is
to the right of the radio. Turn the switch
toward
HIGH for higher airflow in the rear area. Turn
the switch to the
OFF position to turn the system off.
3-4

Downloaded from www.Manualslib.com manuals search engine Rear Air Conditioning System (Option)
You may have rear air conditioning. The rear air
conditioning switch
is located to the right of the heater
controls. Turn the switch toward
HIGH for higher
airflow
in the rear area. Turn the switch to the OFF
position to turn the system off.
Air Conditioning
Before using your vehicle’s air conditioning, open the
windows to clear the vehicle
of hot air. This reduces the
time
it takes for your vehicle to cool down. Then keep
your windows closed for the air conditioner to work at
its best.
You can use MAX A/C with
the temperature knob in the
blue area when it’s really hot outside and you need to
cool the inside air quickly. MAX A/C lets
in only a little
air from the outside.
If you first use MAX A/C, you can then use A/C with
the temperature knob in the blue area, as soon as the
vehicle has cooled down, so outside air will be going
through your vehicle.
3-5

Downloaded from www.Manualslib.com manuals search engine If your vehicle has rear air conditioning, setting it on LO
may enhance the front A/C performance by allowing
trapped refrigerant
in the rear lines to circulate.
The rear air conditioning system will
only send cooled
air
if the front system is on. It can still be used to
circulate air, even if the front system
is off.
When the air conditioning, DEFROST or BLEND is on,
you may notice a slight increase or decrease in engine
speed, due to compressor operation. This
is normal
because the system is designed to cycle the compressor
on and off to keep the desired temperature.
Heating
On cold days, use HEATER with the temperature knob
in the red area. Outside air will be brought in through
the floor outlets. The heater works best if you keep your
windows closed while using it.
If you use the optional engine coolant heater before
starting your engine, your heating system will produce
warmer air faster
to heat the passenger compartment in
cold weather. See “Engine Coolant Heater” in the Index.
Defrosting
Use DEFROST to remove fog or ice from the
windshield quickly in extremely cold conditions. The
temperature knob should be in the red area and the fan
control toward high. The air conditioning compressor
may operate in this setting to dehumidify the air.
The
BLEND setting is useful for cold weather with a
large number of passengers or very humid conditions to
help keep the windshield clear.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use VENT to direct outside air
through your vehicle. Air will flow through the
instrument panel vents.
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 enter the vehicle when the heater or
the air conditioning fan is running.
