Rear Air Conditioning and Heating Systems
(Suburban)
’
If your vehicle has either or both of these systems, you
can increase and decrease the airflow at the rear vents.
Depending on the system
you have and the setting
selected,
you can send cooled or heated air to the rear of
the vehicle.
Rear Air Conditioning (Without Rear Heater)
If your vehicle has rear air conditioning (without rear
heater), the controls are located above the front and
second seats. The front and rear overhead controls let
you increase and decrease the airflow at the rear vents.
To operate the rear air conditioning system, the front air
conditioning system must be on. With the front air
conditioning system off, the rear system controls can be
used to circulate air in the rear of the vehicle.

To increase and decrease the flow of heated air to the
rear floor vents, move the switch marked REAR HEAT
to the blower speed you want.
The knob has three speed positions. To increase the flow
of heated air, move the switch toward HIGH. To
decrease the
flow of heated air, move it toward LOW. To
turn the fan off, move the switch to OFF.
Rear Air Conditioning and Rear Heater
If your vehicle has the rear air conditioning and rear
heater system combination, controls are provided to
regulate temperature, location and speed
of the airflow.
To adjust the air temperature, turn the temperature knob
on the right of the control panel.
For warmer air, turn the knob clockwise toward the red,
and for cooler air, turn the knob counterclockwise.

Downloaded from www.Manualslib.com manuals search engine Your vehicle has air outlets in the center and on the sides
of your instrument panel. You can move the outlets from
side to side or up and down to direct the flow
of air, or
close the outlets altogether. When you close an outlet, it
will increase the flow
of air coming out of any outlets
that
are open. These outlets do not completely shut off
airflow when in a closed vent position.

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 vehicle in cold weather, turn the
blower fan to HI for a few moments before driving.
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.
efogging and Defrosting
D
On cool, humid days, use DEFOG to keep the
windshield and side windows clear. Use DEFROST to
remove fog or ice from the windshield in extremely
humid or cold conditions. Use DEFROST with the
temperature knob toward the red area and the fan control
toward HI.

Towing a Trailer
/I -
If you don’t use the correct equipment and drive
properly, you can lose control when you pull a
trailer. For example,
if the trailer is too heavy, the
brakes may not work well
-- or even at all. You
and your passengers could be seriously injured.
Pull
a trailer only if you have followed all the
steps in this section. Ask your
GM dealer for
advice and information about towing
a trailer
with your vehicle.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
Pulling a trailer improperly can’ damage your
vehicle and result in costly repairs not covered by
your warranty.
TO pull a trailerr dorrectly, follow
the advice in this part, and see your
GM dealer
for important information about towing a trailer
with your vehicle.
Every vehicle is ready for some trailer towing. If yours
was built with trailering options, as many are, it’s ready
for heavier trailers. But trailering is different than just
driving your vehicle by itself, Trailering means changes
in handling, durability and fuel economy. Successful,
safe trailering takes correct equipment, and it has to be
used properly.
That’s the reason for this
part. In it are many
time-tested, important trailering tips and safety rules.
Many
of these are important for your safety and that of
your passengers.
So please read this section carefully ,
before you pull a trailer.

There are many different laws, including speed limit
restrictions, having
to do with trailering. Make sure
your rig will be legal, not only where you live but
also where you’ll be driving. A good source for this
information can be state or provincial police.
Consider using a sway control if your trailer will
weigh
4,000 lbs. (1 800 kg) or. less. You should
always use a sway control if your trailer will weigh
more than
4,000 lbs. (1 800 kg). You can ask a hitch
dealer about sway controls.
Don’t tow a trailer at all during the first
500 miles
(800 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
Then, during the first
500 miles (800 km) that you
tow a trailer, don’t drive over
50 mph (80 kmk) and
don’t make starts at full throttle. This helps your
engine and other parts of your vehicle wear in at the
heavier loads.
If you have an automatic transmission, you can tow
in OVERDRIVE
(OD). You may want to shift the
transmission to DRIVE (D) or,
if necessary, a lower
gear selection
if the transmission shifts too often
(e.g., under heavy loads and/or hilly conditions). Three important
considerations have to do with weight:
the weight of the trailer,
the weight
of the trailer tongue
and the weight on your vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to pull a
trailer are all important. And, it can also depend on any
special equipment that you have
on your vehicle.
Use the following chart to determine how much your
vehicle can weigh, based upon your vehicle model
and options.
Maximum trailer weight is calculated assuming the
driver and one passenger are in the tow vehicle and it
has all the required trailering equipment. The weight of
additional optional equipment, passengers and cargo in
the tow vehicle must be subtracted from the maximum
trailer weight.
Above the 2,000 lbs.
(908 kg) trailer rating, the
engine oil cooler is required on C/K-
1500 models with
5.7L engine and C/K-2500 Suburban models with
5.7L engine and 3.73 axle ratio.
