Instructions on driving


Never move nakaty with the idle engine

Many units thus do not work (for example, signaling devices, the amplifier of a brake drive, the amplifier of the steering mechanism, system of airbags of safety). You subject in danger of and other participants of movement.

Amplifier of a brake drive

Do not begin movement until the vacuum in the vacuum amplifier of brakes will be created, otherwise when braking it is necessary to put considerable effort to a pedal of a brake.

The steering mechanism with the amplifier

If the amplifier of a steering drive refuses, for example, during towage with the idle engine, the car continues to be operated the application of big efforts, however, is demanded.

Frequency of rotation of a shaft of the engine

In all road conditions to operate the car in an optimum range of frequencies of rotation of a shaft of the engine.

Switching on the lowest transfer

At decrease in speed to switch to lower transfer, not to revolve coupling at the increased frequencies of rotation of a shaft of the engine. It is especially important during movement in mountain conditions.


To press a coupling pedal at full capacity, to prevent difficulties at gear shifting and not to damage a transmission. Around pedals there should be no rugs.

Do not use a coupling pedal in the course of driving as a support for a foot, the accelerated wear of disks of coupling otherwise is possible.

Safety of the storage battery

During driving on small speed or stops, for example, at movement in the city, during short-term trips and stoppages, whenever possible to disconnect consumers of the electric power (glass heating, additional headlights etc.).

At start-up of the engine to switch off coupling to avoid resistance of idling of a transmission, to unload a starter and the storage battery.


The engine consumes fuel and when idling.

Already during stops more than 1 minute it is meaningful to stop the engine. Five minutes of operation of the engine on idling correspond to one kilometer of a way.

Mode of compulsory idling

During a mode of compulsory idling supply of fuel is automatically disconnected, e.g., during movement under a bias or when braking.

During this mode not to "increase speed" and not to switch off coupling that the system of shutdown of supply of fuel for fuel consumption reduction worked.

In due time switch transfers

High values of frequency of rotation of a shaft of the engine increase wear of knots of the car and fuel consumption.

Do not lead up frequency of rotation to high values. Too high speed on separate transfers or steps increase wear of knots of the car and fuel consumption.

Management according to indications of a tachometer helps to save fuel. Try to operate on each transfer the car at small frequencies of rotation of a shaft of the engine (a comment between 2000 and 3000 rpm) and with uniform speed.

Pressure of air in tires

Pressure of air in tires below norm leads because of increase in resistance of a kacheniye to increase of expenses for increase in fuel consumption and at the increased wear of tires.

Additional consumers

Inclusion additional consume pour capacities increases fuel consumption.

It is necessary to disconnect additional consumers (the conditioner, warmed back glass, additional headlights etc.) if their work is not required.

Pекомендации on car driving

At movement through pools it is necessary to be extremely attentive as they can hide holes and potholes on which it is possible to damage disks of wheels and a suspension bracket detail.

Moisture on elements of system of ignition can get and stop the engine at movement on the road to time of a heavy rain. A good and well-tried remedy for prevention of an otsyrevaniye of elements of system of ignition is their preliminary processing by water-repellent preparations in aerosol packing.

Special attention and care show the first minutes after the rain beginning as the moistened dust on a paving forms the soap film which is sharply reducing coupling of tires with the road.

Regularly during movement carry out an easy pritormazhivaniye of the car to dry brakes as efficiency of crude brakes sharply falls.

During overtaking include стеклоочис a titel of a windscreen on the maximum mode as it will help to avoid visibility loss at the expense of possible emission of water from under a wheel, overtaken transport. Such precautionary measures are desirable for applying and in case overtake you.

With approach of twilight include a passing beam of headlights. If your car is painted in dark color, a passing beam include a little earlier so against dark asphalt your car is not appreciable and its emergence for drivers of counter transport becomes unexpected.

Be careful on wet or slippery sites of roads. Do not allow sharp braking with risk to block wheels that will inevitably lead to drift. For this purpose operate the car smoothly, without sharp turns.

The brake way depends on reliability of action of the most brake system, a condition of a protector of tires, load of the car, a profile of the road, type and a paving condition, and also from speed of the car. The brake way increases in proportion to a square of speed i.e. if speed increases twice, the brake way increases four times.

That brake shoes did not freeze to drums after movement on wet roads at sharp fluctuations of temperatures, do not leave the car on the open area with the tightened parking brake, without having dried a brake smooth braking at movement to parking.
