Features of driving of the car


Operating the car, do not hold a foot on a brake pedal. Even insignificant on force, but long influence on a pedal can have the consequence heating of brakes, their deterioration, and is possible, and refusal of all system.


At movement on the roads covered with water or a wet dirt, reduce speed as between the tyre and a basic surface the water wedge can be formed. This condition known as hydroplaning, can lead to partial or full loss of contact to a road surface, control loss over the car and braking possibilities.

Pools on road

If it is necessary to go on pools their depth should not exceed 30 see At such depth it is necessary to go with speed of the pedestrian, damage of the engine, an electric equipment and a gear change box otherwise is not excluded.

Shelf behind a back seat

It is impossible to put heavy or firm subjects as at the maneuvers connected with braking, they can injure people being in the car on a shelf.

Hooks for clothes

The clothes on hooks should be hung up so that it did not block the review for the driver. In order to avoid traumas at sharp braking it is impossible to hang up heavy subjects on these hooks.

Features of management of the car in the winter

Трогание from a place

At трогании from a place if the car costs in deep snow, or at departure “враскачку” it is recommended to disconnect system ASC+T/DSC *, address to Section System of automatic stabilisation of stability with a regulator of a twisting moment of engine ASC+T/System of the dynamic control of stability DSC.

Movement in ice

Operating with an accelerator pedal, try to feel car reaction. Avoid also высокооборотных modes and in due time pass to the raised transfers. At movement under a bias or on liftings in due time pass to hill-climbing gears. Maintain a safe distance to ahead going car.


Road conditions are that in the winter that coupling of tyres with a surface are expensive essentially decreases. Being in any situation, the driver should consider the substantial growth of a brake way caused by it.

At braking ABS prevents blocking of wheels thanks to what the car keeps controllability and stability.

If in default ABS wheels nevertheless are blocked, that, without stopping braking, ослабьте pressure upon a pedal exactly so that has renewed качение wheels.

Then increase effort to a pedal, from the moment of blocking of wheels again reduce it, then again increase etc.

Such periodic braking reduces a brake way, allowing to keep controllability of the car at the same time.

Therefore you always can still try to go round a dangerous place after influence easing on a pedal.

On slippery road it is impossible to be switched for car delay to a hill-climbing gear as it can cause sliding of back wheels and, as consequence, control loss over the car.

At sharp braking on slippery road or at non-uniform скользкости a road covering you always should squeeze out a coupling pedal.


Squeeze out coupling and dump gas or translate selector AT lever in position N. Operating with a steering wheel, try to level the car and to return it controllability.


Include the first transfer or transfer of a backing or translate selector AT lever in position of the River Depending on a road bias tighten a lay brake. In avoidance прихватывания overlays of a lay brake to drums because of a frost or corrosion the brake should be dried preliminary, slightly tightening it on small to a course to a full stop of the car. Thus do not create hindrances to other participants of traffic, the following behind you.

At the tightened lay brake stoplights do not burn.

Trailer towage

Movement with the trailer shows increased requirements both to the towing car, and to the driver.

The trailer limits manoeuvrability, ability to overcoming of liftings, dispersal and braking possibilities, influencing dynamic properties and controllability of the car.

About admissible weight of towed cargo and about a safe load on дышло you will find the data in Specifications. The admissible weight of towed cargo is specified also in the car passport. To consult about possibility of its increase it is possible on any HUNDRED BMW.

Tjagovo-coupling устройство*

The optimum design of a running gear of your car guarantees high traffic safety and comfort, and also possibility of a sports manner of driving.

If the tjagovo-drawbar is established at factory the car is equipped strengthened подвеской* the back bridge which compensates weight of the tjagovo-drawbar and optimises dynamic characteristics at movement without the trailer.

At дооснащении the car tjagovo-coupling устройством* it should have certification BMW. And its installation should be made technically competently on firm HUNDRED. It is recommended also дооснастить the car the strengthened suspension bracket.

Other systems of a suspension bracket offered to free sale in system of trade by autoaccessories, have no certification BMW.

With a spherical head it is necessary to look after the tjagovo-drawbar according to applied instructions of the manufacturer that will provide possibility of fast installation and device dismantle.

Tjagovo-drawbar installation limits a system effectiveness of the back bumpers absorbing energy of collisions on small speeds at the expense of elastic deformations.

Stabilising adaptations are recommended to be applied first of all at towage of the heavy trailer. To consult about it it is possible on any HUNDRED BMW.

Cover of a nest for tjagovo-coupling устройства*


1 Undertake cut in the bottom part of a cover of a nest and pull it back.
2 Before removal and installation of a spherical head familiarise with the applied instruction.


Insert a cover in directing and then press it.

Safe load on a support дышла

It is a question of loading from which дышло the trailer presses on a spherical head of the tjagovo-drawbar. To define it it is possible, for example, floor household scales.

By the rules operating in Germany, it is size should make a minimum of 25 kg.

The admissible size cannot be exceeded (address to Specifications), its maximum use however is desirable.

The weight from which дышло the trailer presses on the support, influences behaviour of the car. Therefore at movement with the trailer admissible indicators of full weight of the car and loading on road from its back bridge should not be exceeded. Load-carrying capacity partially decreases because of subtraction from it weight of the tjagovo-drawbar, and at movement with the trailer also weights from which дышло the trailer presses on the support. It should not be exceeded and an indicator of an admissible lump of the car with the trailer.


Trailer loading should be made so that cargo took places as it is possible more low and as it is possible more close to a bridge axis.

Fall of the centre of gravity of the trailer essentially improves traffic safety of the car with the trailer.

It is impossible to exceed indicators of a lump of the trailer and admissible weight of towed cargo. The smaller size is defining.

At trailer purchase it is recommended to request from the seller guarantee acknowledgement by the manufacturer of its actual weight and load-carrying capacity.

Movement on lifting

The size of an overcome bias (measured on a sea level) is limited 12 % for safety reasons and in order to avoid creation of hindrances to a transport stream, and at the increased weight of towed cargo (in the resolved cases) - 8 %.

From experience it is known that in process of height increase above sea level capacity of the engine falls. At movement on mountain roads it is necessary to remember, in particular, ability deterioration to троганию from a place on lifting in this connection it is necessary to refuse full use of admissible limits of weight of the car and the trailer.

Movement under a bias

The special attention is demanded by descents of roads. On an entrance to them it is necessary to be switched to a hill-climbing gear, if necessary up to the first (at complete set АТ the selector lever is translated in position 2) then on small speed to move under a bias.

The maximum speed

The maximum speed of movement with the trailer on roads Germany is limited 80 km/h. Admissible weights of towed cargo are defined so that at this speed is provided normal траекторная stability. Even if in other countries movement with higher speed is authorised, all the same for safety reasons it is not necessary to go faster.

Trailer wagging can be eliminated only immediate braking.

Pressure of air in tyres

Pressure of air in car and trailer tyres should be a subject of special attention. For the trailer the norms established by its manufacturer are defining.

Rear-view mirrors

If at movement with the trailer the review sector through serially established external rear-view mirrors appears insufficient rules offer to establish instead of them two mirrors in which the driver can see the trailer to back edge of each of boards. Such mirrors, including with adjustable arms, you can get on HUNDRED BMW.

Electric equipment

By transportation the trailer-summer residence it is necessary to take into consideration the raised expense of the electric power. Therefore taking into account the limited capacity of the accumulator inclusion of consumers of a current should be short.

Before departure necessarily check work of back lanterns of the trailer.
