Engine Coolant Heater If your vehicle has a diesel engine, it is equipped with an engine coolant heater. An engine coolantheater is optional on gas enginevehicles. If you use the engine coolant heater before starting your engine (in cold weather (20" F, (-8" C), or lower) your heating system will produce warmer air faster, to heat the passenger compartment in cold weather. The use of an engine coolantheater also reduces the time it takes for the engine to reachnormal operating temperature, and shortens the time it takes the heaterto reach full output. For more information, See "Engine Coolant Heater" in the Index. Diesel Engine Heater Output If you idle your diesel engine for a long time when it's cold outside, your heater may blow out cool air. This isnormal. When you increase the engine speed, your heater should blow out warmer air. If it doesn't, your coolant level may be too low. See "Engine Coolant" in the Index to see how to check your coolant level. Rear Air Conditioning and Heating Systems (Suburban) If your vehicle has either orboth of these systems, you can increase and decrease the air flow at the rear vents. Depending on the system you have and the setting selected,you can send cooled orheated 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. Thefront and rear overhead controls let you increase and decrease the air flow at the rear vents. 3-4

fuel economy. This setting also cools the air the fastest and can be used
to
keep “unwanted odors”
and/or
dust
from entering the vehicle. When using
the air conditioner, turn
off recirculation after the vehicle reaches
a
comfortable interior temperature.
When the right knob
on
the control panel is between HEAT and DEFROST,
the
recirculation
feature will not function.
N C
-
This button, between the middle and right knobs, allows the air
coming into your vehicle
to
be cooled and directed through
the
instrument
panel vents. This setting
is
useful for normal cooling on hot days. When you
first
use
A/C
with the recirculation button pushed in,
turn
off recirculation
as
soon
as the vehicle reaches a
comfortable
interior temperature.
Engine
Coolant
Heater
If your vehicle has a diesel engine,
it
is equipped with
an engine
coolant
heater. An engine
coolant heater is optional
on
gas
engine vehicles. If you
use
the engine coolant heater before starting your engine (in cold weather
(20”
F,
(-8”
C),
or lower) your heating system
will
produce warmer air
faster, to heat
the
passenger compartment
in
cold weather.
The
use of an engine
coolant heater also reduces
the
time
it
takes for
the
engine
to
reach normal operating temperature, and shortens the time it takes
the
heater
to
reach full output. For more information, See “Engine Coolant
Heater” in the Index.
Diesel
Engine
Heater
Output
If
you
idle your diesel engine
for
a
long
time when it’s cold outside, your
heater may blow out cool air. This
is normal. When
you increase the engine
speed, your heater should blow
out
warmer air. If it doesn’t, your coolant
level
may be too low. See “Engine Coolant”
in
the
Index
to
see
how to
check your coolant level.
Rear
Air
Conditioning
and
Heating
Systems
(Suburban)
If your vehicle has either
or both of these systems, you can increase and
decrease the air flow at the rear vents. Depending
on
the
system
you
have
and the setting
selected, you can send cooled
orheated 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 air flow
at
the rear vents.
