IMPORTANT!
To ensure trouble-free operation of the automobiles, we
recommend that You should attentively familiarize yourself with the
present publication and follow all the operating and maintenance
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,
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
4. When descending a steep downhill:
- 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 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.
8. Avoid falling acides, soda solutions, braking fluids, antifreeze
and fuel on the painted surfaces of the body and rubber parts.
9. 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.
10. To avoid heavy loads on the a le differential, do not allow
a prolonged slipping.
11. Use the warmth-keeping hood for radiator shell to provide
the proper temperature condition for engine at an ambient tempera-
ture below 0 °C.
12. When the automobile is to be operated at a temperature
below -30 °C, do not fail to disengage the front a le.
13. The automobile is provided with a towing hook allowing a
short-time operation with a trailer. Do not tow a trailer on rugged
ground.
14. Do not transport at the same time passengers and cargoes
(e cept for a hand luggage) in the passenger and the sanitary
compartments of the automobiles ÓÀÇ-2206, ÓÀÇ-3909,
ÓÀÇ-3962, in the cargo compartment of the automobile ÓÀÇ-3741
equipped with the hinged seats, on the platform of the automobiles
ÓÀÇ-3303, ÓÀÇ-33036, ÓÀÇ-39094, ÓÀÇ-39095 equipped with
the hinged seats and the tarpaulin.
The automobile design is provided with special parts to fasten cargoes.
15. Since efforts are continually made to improve the reliability
and performance of the automobiles, minor changes may be
introduced without special notices.

INTRODUCTION
The automobiles ÓÀÇ with a wheel arrangement 4x4 are
designed for operating on roads of all types, at all climatic
conditions, in all seasons, at ambient temperatures from -45 °Ñ
to + 40°Ñ .
The OJSC UAZ manufactures automobiles of the following
models and modifications:
ÓÀÇ-3741, ÓÀÇ-37419 (Fig. 1) - vans with all-metal
closed wagon-type body divided into a two-seat cab and a cargo
compartment. The vans are intended for cargo transportation;
ÓÀÇ-3962, ÓÀÇ-39629 (Fig. 2) - ambulance cars with
wagon-type body divided into a two-seat cab and a sanitary
compartment. The ambulance cars are intended for transportation
of invalids and could be used for service of emergency aid in
towns and countries;
ÓÀÇ-39625 and ÓÀÇ- 396259 - special vehicles with wagon-
type body divided into a two-seat cab and a passenger/cargo
(seven-seat) compartment. The vehicles are intended for
passenger/cargo transportation. The vehicles ÓÀÇ-39625 and
ÓÀÇ-396259 are manufactured on the base of the vehicles
ÓÀÇ-3962 and ÓÀÇ-39629 correspondingly and have the same
specifications;
ÓÀÇ-3909, ÓÀÇ-39099 (Fig. 3) - special vehicles with
wagon-type body divided into a two-seat cab, a five-seat
passenger compartment and a cargo compartment. The vehicles
are intended for cargo/passenger transportation;
ÓÀÇ-2206, ÓÀÇ-22069 (Fig. 4) - buses with wagon-type
body divided into a two-seat cab and a passenger compartment.
The buses are intended for passenger transportation;
ÓÀÇ-3303, ÓÀÇ-33039 (Fig. 5) - cargo vehicles with two-
seat cab and wooden platform. The cargo vehicles are intended
for cargo transportation*;
ÓÀÇ - 33036 (Fig. 6) - a cargo vehicle with the enlarged wheel
base, two-seat cab, metal or wooden platform.The cargo
vehicles are intended for cargo transportation*;
* To transport passengers on the platform equipped with hinged seats at the front
side is allowed, if there is no cargo on the platform.

6
ÓÀÇ-39095 (Fig. 7) - a special vehicle with the enlarged
wheel base, two-seat cab and metal platform for municipal
econimy, cooperative and individual farmings. The vehicles are
