INSTRUMENT PANEL
The instrument panel is composed of several parts. The
top consists of two safety pads with a tidy box mounted
between them. The lower part is made up of a three-part
switch panel and a knee quard mounted along the bottom
edge of the switch panel. The knee guard also incorporates a courtesy handle located under the glove compartment.
A three-part screen is mounted under the instrument
panel.

SEAT BELTS
In the front seats there are reel belts with buckle lock.
The belt consists of a strap with one end secured at the
bottom. The free end runs through an eye up on the
door pillar and into the reel which, on 2-door cars, is located inside of the rear side trim and on 4-door cars, on
the door pillar.
The belt is fastened by pulling the strap out and inserting it directly into the buckle lock and dropping the
yoke, which locks automatically. The strap can run freely
through the buckle lock and the running eye and is thereby automatically adjusted. The belt is released by pressing the key marked "press".
In the back sea , there are reel belts on the two outer seats.
The reels are mounted on the parcel shelf (Saab 99 Combi
Coupe inside the side trim) and the fixed end of the strap
is anchored behind the outer end of the seat cushion. The
strap is equipped with a sliding buckle which is secured in
a locking device1between the passengers.
The reels have two locking mechanisms. One mechanism
is actuated by sudden acceleration of the reel (i.e. when
the strap is pulled out with high speed). The other is actuated by a pendulum which senses the movements of
the car. A two-point lap belt with manual adjustment is
provided for th13rear seat passenger in the middle of the
rear seat.

HEATING AND VENTILATION SYSTEM
GENERAL
The heating and ventilation system consists of the following components:
Air intake and valve housing in the engine compartment.
Located below the instrument panel are the valve housing,
defroster nozzles, hoses to the side window defrosters,
fresh air outlets and heater control.
In the passenger compartment are the warm air ducts and
a valve housing for the rear seat and rear window defroster. Located in the trunk are the evacuation boxes with air
outlets.
The fan casing contains both fan and heat exchanger. The
casing is divided up into three zones with partitions. The
two outer zones admit cold air and are connected to the
fresh air channel and the three fresh air outlets. In the
centre zone, the air passes through the heat exchanger
which thereby supplies hot air to the coupe.

The fan is a cross-flow fan with a common impeller for
all three zones. The flow of the air is regulated by a pearshaped guide vane around which the air circulates.

PATH OF AIR
The air passes into the fan casing through the air intake
in the dash panel.
The air is distributed by a flap valve housing to the defroster nozzles and other outlets in the coupe. A continuous moulded plastic channel leads from the valve housing to the three fresh air outlets. The defroster nozzles
to the rear window are located in a raised defroster channel in the front edge of the parcel shelf. The nozzles are
directed towards the middle of the rear window so that
the part of the window in the line of sight from the rearview mirror is the first to be defrosted.
As from model 1977, the intake for the cold-air zones are
equipped with a valve which can be set to the "Summer"
or "Winter" position from the engine compartment.
When the outside temperature is low, the heating of the
passenger compartment will be more efficient if the coldair intake is closed (valve in "Winter" position), as this
eliminates any warm air losses through the impeller or
fresh-air ducts. However, when the valve is in this position, cold air cannot be admitted through the fresh air
wnts.

The system is controlled as follows:
a. Defroster valve, windshield, controlled by the lefthand knob on the control panel.
b. Defroster valve, rear window, controlled by the righthand control between the front seats.
c. The water valve is controlled by means of the centre
knob on the control panel. The valve is thermostatically controlled to keep the warm air temperature
constant.
d. Ventilation valve, front floor, controlled by means of
the right-hand knob on the control panel.
e. Ventilation valve, rear floor, controlled by the lefthand control between the front seats.
f. The fresh air valve is controlled by the three controls
adjacent to the outlets on the instrument panel. The
fresh air outlets can be directed as desired.

FAN CASING
Removal and installation
For removal or installation of the fan casing, it is recommended that the power plant be removed.
On installation, the insulating felt should first be glued
to the fan casing. Siide the casing into position from the
front. Check that the insulating felt does not slide out of
position during installation. The fan casing retaining
screws become accessible from inside the car once the
safety padding with glove compartment and the instrument section have been removed.
