This instruction manual contains the brief description of the
design and necessary operating and maintenance instructions.
Since efforts are continually made to improve the reliability
and performance of the automobiles, minor changes may be
introduced without special notice.
e wish You a good trip!

IMPORTANT!
To ensure trouble-free operation of the automobiles, we
recommended that You should attentively familiarize yourself with
the present publication and follow all the operating and mainte-
nance instructions laid down therein.
You can trust the maintenance of your automobile to one of the
service stations recommended by the Sellers. These service stations
are well stocked with spares, special appliances and tools. All the
maintenance operations are performed by e perienced specialists.
Safety instructions
1. Before a trip, check the condition of the lock mechanisms of
the hood and the body doors.
2. When using the low-freezing fluid, leaded gasoline and brake
fluid, do the following:
- avoid any operations which could lead to penetration of these
fluids or their steams into the mouth cavity;
- do not let to dry the liquid which is occured on the skin, but
wash it off right away with warm water and soap;
- never spill liquids in the interior or indoors. Should spillage
occur, wash off the spilled place with water and ventilate it;
- take off the spilled clothes, wash and dry it outdoors;
- wet with kerosene the carbon of leaded gasoline when scraping
it off to avoid penetrating of to ic particles of carbon into the
respiratory organs.
3. To avoid scalding, open the radiator cap of the engine cooling
system with care.
4. Do not warm up the automobile assemblies with free flame.
5. Cut out the storage battery after driving and also in case of
short circuit of wiring.
Precautions
1. Do not begin driving the automobile with the cold engine. After
starting the engine from cold, never run it at a high crankshaft speed.
2. Cut in the oil cooler at an ambient temperature above 20
°C,

4
and when riding under hard service conditions (at heavy loads
and a high crankshaft speed) independing on ambient temperature.
3. Shift the gearbo in the reverse gear and shift the transfer case
to low range only when the automobile is stationary
4. When descending a steep:
- do not shut down the engine to avoid loss of the efficiency of
the brakes provided with the vacuum booster;
- do not disengage the clutch to avoid breaking of the clutch driven
disk.
5. When riding on dry hard-surface roads, disengage the front
a le. When the front wheels are disengaged, never engage the front a le.
6. If one of the hydraulic brake circuits is a failure, the travel
of the brake pedal is increased, and the braking efficiency is
decreased.
7. When driving the automobile equipped with the hydraulic
steering booster, it is not recommended to hold the steering wheel
at the e treme position for more than 5 s in order to prevent
overheating of oil and failure of the hydraulic steering booster pump.
8. When using the gun with the unscrewed tip, take out the spring
and the ball in order to avoid their falling in the assemblies with
liquid grease.
9. Avoid falling acides, soda solutions, braking fluids, antifreeze
and fuel on the painted surfaces of the body and rubber parts.
10. Do not allow impact loads on the chassis of the automobile.
When a strong impact of the front wheels is occured, inspect
carefully the wheels, all parts of the front a le, steering rods,
steering mechanism, oil sump, eliminate deffects, if required.
11. To avoid heavy loads on the a le differential, do not allow
a prolonged slipping.
12. Use the warmth-keeping hood for radiator shell to provide
the proper temperature condition for engine at an ambient tempera-
ture below 0 °C.
13. When the automobile is to be operated at a temperature
below -30 °C, do not fail to disengage the front a le.
14. The automobile is provided with a towing hook allowing a
short-time operation with a trailer. Do not tow a trailer on rugged
ground.
15. Since efforts are continually made to improve the reliability
and performance of the automobiles, minor changes may be
introduced without special notices.

an engine of uprated power.
AUTOMOBIL MARKING
The identity number of the automobile is indented on the
nameplate, on the level flange of the body front upper panel
(Fig. 5).
The nameplate "Identification Data" is fixed at the central
pillar of the r.h. body side (at the aperture of the rear side door).
The body number is indented on the level flange of the body
front upper panel (under the hood, on the l.h. side).
The chassis number is indented on the frame r.h. rear cross-
member.
The engine number is indented on the l.h. side of the
cylinder block (Fig. 6).
* Some automobiles could be equipped with the driving axles with the hub drive

position III, take it out and rotate the steering wheel in any
direction till click is heard; this means that the lug of the
interlock device is in register with the recess of the stop-bush of
the steering wheel shaft. To unlock the steering gear, insert the
key into the ignition switch, and by turning the steering wheel
to the left and to the right, turn the key clockwise to the position I.
