What influences traffic safety?

It is necessary to remember the following:

Do not distract and do not give to distract itself from control of a road and transport situation, for example, by your passengers, or telephone conversations.

Never take the wheel in case of violation of ability to operate the car (for example, as a result of reception of medicines, alcohol, drugs).

Always maintain speed according to a condition of the carriageway, and also traffic conditions of transport and weather conditions.

At long trips regularly (the latest every two hours) do breaks.

Whenever possible do not take the wheel tired or when hurry.

The correct position of the driver on a seat

The correct position of the driver on a seat is important for the safe and not tiring movement.

	The minimum distance of the driver in relation to a steering wheel
	Correctly established driver's head restraint

For your safety and decrease in danger of traumatizing at accident the following option of adjustment of provision of a seat of the driver is recommended:

• So adjust the provision of a steering wheel that the distance between a steering wheel and a breast made at least 25 cm.
• So adjust the longitudinal provision of a seat of the driver that slightly bent feet it was possible to squeeze out completely a pedal of an accelerator, brakes and couplings.
• Be convinced that you can get the most top point of a steering wheel.
• So adjust the provision of a head restraint that the upper edge of a head restraint and the top part of your head were on one line.
• So adjust a back inclination that the back the surface completely adjoined to a back.
• Correctly impose and fasten a seat belt.

Regulation of provision of a seat of the driver, see Seats and niches.

The correct position of the forward passenger on a seat

The minimum distance between the forward passenger and the dashboard has to make 25 cm. It will provide the maximum protective effect in case of disclosure of a safety cushion.

The following adjustment of provision of a seat of the forward passenger is recommended:

• Displace a seat of the forward passenger as it is possible further back.
• So adjust a back inclination that the back the surface completely adjoined to a back.
• So adjust the provision of a head restraint that the upper edge of a head restraint and the top part of your head were on one line.
• Both feet have to be in space for feet before a seat of the forward passenger.
• Correctly impose and fasten a seat belt.

In exceptional cases you can disconnect a pillow of the forward passenger.

Correct position of passengers of back seats

Passengers of back seats have to sit directly, keep feet in space for feet and to be correctly fastened by seat belts.

For decrease in danger of traumatizing in case of sudden braking or accident passengers of back seats need to remember the following:

• So adjust the provision of a head restraint that the upper edge of a head restraint and the top part of your head were on one line.
• Both feet have to be in space for feet before a back seat.
• Correctly impose and fasten a seat belt.
• In transit children use suitable children's systems of laying and a tension of seat belts.

Correct provision of head restraints

Correctly established head restraints are an important component of the concept of protection of the driver and passengers and in the majority of emergencies can reduce danger of traumatizing.

	Correct the established head restraint (front view)
	Correctly established head restraint (side view)

For achievement of optimum protective effect the provision of head restraints has to be correctly adjusted.

So adjust the provision of a head restraint that the upper edge of a head restraint and the top part of your head were on one line.

Regulation of provision of head restraints, see Seats and niches.

Zone of pedals

Never have to stir use of all pedals subjects or foot rugs.

• Be convinced that you will always be able freely to squeeze out a pedal of an accelerator, a brake and coupling.
• Be convinced that pedals freely come back to a starting position.

In case of refusal one of contours of brake system the brake pedal for a stop of the car is required to be squeezed out with big effort than usually.

Foot rugs from the driver

Only foot rugs which do not come into a zone of pedals and which can be fixed reliably in space for feet are allowed to application.

Be convinced of reliable fixing of foot rugs and that during the movement they will not interfere with a manipulation pedals.

Only foot rugs which do not come into a zone of pedals and which can be fixed reliably in order to avoid their sliding are allowed to application. *

Correct placement of baggage

Luggage carrier

All subjects of baggage have to be reliably placed in a luggage carrier.

The loose, moving in a luggage carrier subjects, can negatively influence as a result of change of the center of gravity dynamic properties of the car or traffic safety.

• Distribute freight in a luggage carrier evenly, see Seats and niches.
• Place heavy subjects as it is possible further ahead of a luggage compartment.
• By means of the cargo holding grid * fix heavy subjects for the lifting eyes located in a luggage carrier.

Belts, suitable to lifting eyes, for fastening of baggage can be got in a distribution network.

Lifting eyes

Loose freight constitutes danger to the driver and all passengers.

For reliable fastening of freight use lifting eyes, see. "Loading of a luggage carrier" in the section of the Seat and niche.

In case of collision or accident even small and easy subjects can receive so a lot of energy that they can cause the extremely severe injuries. The size of "energy" depends in very big degree on the speed of the car and mass of a subject. However more significant factor is car speed.

Example: in the car there is a loose subject weighing 4.5 kg. In case of frontal collision at a speed of car of 50 km/h, this subject develops forces corresponding to its twentyfold weight. It means increase in weight approximately to 90 kg. You can imagine all picture of traumatic consequences if this flying on snaryad salon gets to someone.

Seat belts

Fastening by seat belts with three-point fastening

Fasten a belt and only then begin the movement!

	Provision of a head restraint and seat belt
	Driver's seat: lock and fastener of a belt

PERFORMANCE ORDER

Establish correctly forward seat and a head restraint and only then fasten a belt, see. "Seats and niches" in the section of the Seat and niche. Undertake a belt fastener, smoothly extend a tape, impose it over a breast and a belt. Insert a fastener into a nest of the corresponding lock before the heard click. Surely pull for a belt and be convinced that the lock is locked.

Each belt with three-point fastening is completed with the mechanism of automatic retraction of a belt. Automatic equipment of retraction of a belt provides full freedom of movements at its smooth tension. However at sharp braking it blocks a belt. Automatic equipment blocks belts also at dispersal of the car, at the movement on mountain roads and on turns.

The provision of tapes of a seat belt with three-point fastening

The provision of tapes of a belt is of great importance for protective effect of seat belts.

Provision of a diagonal and zone tape of a seat belt

Possibilities of regulation of provision of a seat belt on growth:

• Adjustment of height of a belt
• Regulation of height of forward seats

Fastening by seat belts with three-point fastening by pregnant women and the provision of tapes of a belt

The best protection for yet not seen the light child is continuous and correct fastening by a belt by the pregnant woman.

Provision of tapes of a belt of the pregnant woman

Pregnant women also always have to be fastened by belts.

PERFORMANCE ORDER

Establish correctly forward seat and a head restraint and only then fasten a belt, see. "Seats and niches" in the section of the Seat and niche. Undertake a belt fastener, smoothly extend a tape, impose it over a breast and a belt. Thus the zone tape of a belt has to settle down as it is possible below to hips that there was no pressure upon the lower part of a stomach. Insert a fastener into a nest of the corresponding lock before the heard click. Surely pull for a belt and be convinced that the lock is locked.

Adjustment of height of fastening of a belt

PERFORMANCE ORDER

Displace up or down a cursor with a reverse buckle that the diagonal tape appeared approximately at the level of the middle of a shoulder, but did not cover a neck at all. After adjustment pull a belt to be convinced of reliability of fixing of a buckle.

For regulation of tapes of belts of forward seats it is possible to use possibility of change of height of seats also.

Regulation of a belt of an average back seat

Lengthening of a belt

For lengthening of a belt hold a fastener at right angle concerning a tape and stretch a tape at necessary length. This process is facilitated by tightening of a fastener and buckle in the longitudinal direction.

Shortening of a belt

For shortening it is enough to pull for the free end of a belt. Surplus of a belt is cleaned by shift of a plastic cursor. At correctly fastened belt the red button is from outer side of the lock of a belt.

Otstyogivaniye of seat belts

The belt comes unfastened pressing of the red button of the lock.

Press the red button of the lock. Thus the fastener is pushed out from a nest under the influence of a spring.

For simplification of operation of automatic equipment of retraction of belts take away a fastener a hand back.

Long blocking of seat belts

For fastening of a children's seat long blocking of belts with three-point fastening is possible.

For fastening of the children's seat established on a seat of the forward passenger or back seats long blocking of belts with three-point fastening, see below "Fastening of a children's seat" is possible. Such blocking of a belt provides strong fastening of a children's seat in the car.

Natyazhiteli of tapes of seat belts

Principle of action

At dangerous frontal and side crashes of a tape of the fastened belts with three-point fastening automatically stretch.

Safety of the fastened driver and passengers increases, in addition to safety cushions, the natyazhitel of tapes of a belt located on mechanisms of automatic retraction of seat belts with three-point fastening.

The system works at dangerous frontal collisions from sensors. Thus the fastened belts with three-point fastening automatically stretch see below "Important instructions concerning natyazhitel of tapes of seat belts".

At stronger collisions safety cushions in addition reveal. Natyazhiteli of tapes of belts is not worked at back collisions and capsizing of the car.

Important instructions concerning natyazhitel of tapes of seat belts

Natyazhiteli of tapes of belts is not worked at easy frontal, side and back crashes, in case of capsizing of the car, and also at accidents without influence of significant forces in front.

At operation of natyazhitel of tapes of belts the smoke is allocated. The smoke does not testify to fire of the car.

At utilization of the car or separate components of system surely take precautionary measures.

Description of safety cushions

General instructions on safety cushions

The pillow represents part of the general concept of passive safety.

At dangerous frontal collisions the system of forward safety cushions together with three-point seat belts provides additional protection of area of the head and thorax of the driver and forward passenger.

At strong side crashes lateral and head pillows reduce danger of damages of the passengers who are in a blow zone

Seat belts, along with their traditional protective function, have to hold in case of accident the driver and the forward passenger in such situation that pillows could reveal and provide additional protection correctly.

Security systems work only at the included ignition. Readiness of function of pillows is controlled by electronics and brought to indication by means of a control lamp of "airbag".

The main components of system of pillows are

The electronic control actuation device (the control unit and sensors) both forward pillows lateral and head pillows a control lamp in a control panel.

The following testifies to malfunction of system

At inclusion of ignition the control lamp does not light up, the control lamp does not die away about 3 seconds later after ignition inclusion, after ignition inclusion the control lamp dies away and lights up again, the control lamp lights up or blinks during the movement.

Under what conditions work safety cushions?

Safety cushions work at dangerous collisions.

Safety cushions of the driver and the forward passenger work at dangerous frontal collisions.

At strong side crashes lateral pillows work together with a head pillow of the relevant party of the car.

In special emergencies can work both forward, and lateral pillows together with the corresponding head pillow.

Safety cushions do not work at easy frontal and side crashes, arrivals behind and capsizing of the car. In such situations of passengers traditionally protect the fastened seat belts.

Factors of disclosure of pillows

There are no uniform criteria of operation of pillows in each concrete situation. It is explained by the extremely different specifics of accidents. An important role is played, for example, by such factors as properties of object of collision with the car (firm, soft), a collision corner, car speed, etc.

Condition of operation of safety cushions in case of collision delay size is decisive. Car sensors together with the control unit define severity of accident and by that promote purposeful and timely operation of system of laying and a tension of seat belts. Saf
