Tax systems speed (speed action) and Speedtronic

General information

The tax system the speed (speed action) comes to a basic equipment of the considered models. The system automatically allows to support the chosen speed of the cruiser of the movement of the car without influence on the accelerator pedal. Value of speed of the cruiser should not be lower than 40 km for an hour. The tempostata appendix becomes especially convenient at the long movement after malosagruschennym to direct land autobahns. For the purpose of reliability not recommended, after twisting, richly existing in changes, roads to accept action of speed at the movement in the city on slippery tourist providing, during a heavy rain and at other adverse weather conditions. In above-mentioned cases the driver has to have an opportunity to completely control the mode of the movement of the car.



Abuse of tempostata can be the cause of transport accident! Accept tax system speed only at the movement after free autobahns and under favorable weather conditions.

During functioning of system there can be an automatic shift of the accelerator pedal which not to hold it from a leg for prevention of damage a support and axial mechanisms at the same time is necessary!

The lever switch of management of functioning tempostata is located at the left on a tax crevice, these are above installations podrulewogo as the switch is combined.

The appendix / exception of system is made by means of the equipped lamp of the button of the main tempostata switch established Control and is followed by wear of the corresponding examination of a lamp on the panel of devices of the car.

Management of functioning of tempostata

Action of rate of a standard design

The switch of management of functioning tempostata is located on the right on a tax crevice


1 — introduction of the current value of speed in memory of system (otschat of levers) / increase in speed is short-term (the otschatym lever to adhere)
2 — introduction of the current value of speed in memory of system (otschat of levers) / immersion of speed is short-term (the otschatym lever to adhere)
3 — an exception (value of the cruiser of speed remains in memory of system)
4 — an appeal of value of speed of the cruiser on memory of system

The design of the tempostata switch allows, in memory of system as any current speed of the cruiser of the car if it passes value into 40 km for an hour, - to enter rather short-term otschat the lever upward or down. After introduction of speed of the cruiser you dismiss the accelerator pedal.

Increase and immersion of value of speed of the cruiser is made by means of lever otschimanija upward / later below as appropriate.

Short-term acceleration of the car, can be made at repair execution, by means of Ausquetschens of the accelerator pedal, for example, - after pedal otpuskanija speed to stimulated will automatically fall to memory of tempostata of value of the cruiser.

After exile of the car up to the speed of 40 km for an hour cruiser speed above can be stimulated in memory of tempostata is caused by means of short-term Aufschiebens of the lever on itself.

Activate a cruiser speed appeal software memory of system only if you know its value and are ready to the movement with neju.

At the movement with tempostatom downhill is made and uphill deviations of a preset value of the cruiser of speed can occur.

At key poworatschiwanii in the ignition lock in situation 1 or 0 branch happens stimulated in memory of tempostata of value of the cruiser.

Action of speed with the speed limiter

Order of use of the tempostata switch with the speed limiter

1 — increase in speed
2 — appendix / activization of the limiter
3 — an exception
4 — reduction of speed

The tempostata appendix is made by means of switch lever otschimanija down.

The principle of functioning of tempostata in the normal mode is similar above for standard systems is described.

At the current speed of the movement - it tempostata design allows 35 km below for an hour to introduce restriction of the bystry mode at introduction in memory of tempostata of value of admissible speed limit in 30 km for an hour. For activization of the limiter of speed it is necessary to take it is back necessary also the switch lever down, - on the screen value of 30 km for an hour is lit.

At the movement downhill the running speed can pass admissible Höchstbedeutung (30 km for an hour) a little.

Speedtronic system

Order of use of the tempostata switch on the models equipped with the Speedtronic system


1 — activization of the limiter of speed / increase in value of speed of the cruiser with a step to 10 km for an hour
2 — activization of the limiter of speed / immersion of value of speed of the cruiser with a step to 10 km for an hour
3 — a speed limiter exception
4 — an appeal / subtlety of the value of restriction of speed registered in memory regulation of speed with a step to 1 km for an hour
5 — switching of the tempostat/Speedtronic modes

The Speedtronic system represents from itself action of speed with peremenno and constantly from the speed limiter.

podrulewoj allows the switch of management to switch from the tempostata mode in the mode of restriction of speeds at change of own functions. Switching is made by means of pressure in a part of a forehead of a hvataniye of the lever of the switch.

In the tempostata mode of the rule of use of the switch are similar above for standard systems is described.

variabele speed limiter

variabele allows the limiter of speed due to restriction of changes of the motor not to pass some threshold of speed, for example, in need of attention of traffic regulations.



Do not forget that responsibility for excess of the bystry mode is always born by the driver!

Activization of the variabelen mode of restriction of the bystry mode is made by means of pressure in a part of a forehead of a hvataniye of the lever of the tempostata switch and is followed by wear of the yellow LIM indicator on a hvataniye, the similar inscription is lit on the screen.

The limiter is only activated provided that the current speed of the movement of the car does not differ from the Höchstbedeutung system registered in memory it is more than on 30 km for an hour.

Change of value of the maximum speed is made by means of switch lever otschimanija upward or down. The chosen value is displayed the display of data. At the working motor introduction of any restriction of the bystry mode is possible, with value of 30 km for an hour beginning.

A certain border of speed can pass only when squeezing the accelerator pedal before blow (the appendix of the kickdown mode) to be.

Exit from the mode of restriction can be made by means of short-term otschimanija of the lever of, or from pressure for an end face of its hvataniye, - the announcement of LIM from the screen has to vanish. Automatic shutdown of the limiter happens at exile of the car in the kickdown mode up to the speed which passes Höchstbedeutung more than to 20 km for an hour.

If the limiter does not cope with the putting task, for example, at the movement downhill, the alarm buzzer is activated, and begins the inscription LIM to blink on the screen of the display of data.

Owing to design features of the statement of a speedometer can differ from speed limiter devices slightly.

Unlike the tempostata mode the brake does not lead squeezing of a pedal of noschnogo to shutdown of the limiter of speed.

Constant limiter of speed

By means of the constant limiter the speed limit of the movement of the car, for example, in working order it with winter tires can be limited.

Restriction can be defined of 190 km for an hour up to the possible speed limit of the movement of the car. A certain constant restriction of speed works also in case of activization of variabelen of restriction away.

For activization of the mode you press in a part of a forehead of the switch. You transfer the Selektors AT lever to situation "R", and you do not start a key in the ignition lock - in situation 2 (motor). Then, expected about a second, you sup the lever on yourself, - on the screen value of speed will be lit. At lever otpuskanii the announcement will begin to blink, - the speed device by means of Aufschiebens of the lever is made upward or down. Introduction of the chosen value in memory of system is made by postponement of the lever on itself, - the confirming sound signal has to ring.
Withdrawal of the device can be made as a last resort, - you increase the entered value, on the screen a triple hyphen (-it will be lit), then you sup the lever on yourself to a sound signal.

At approach of the current speed of the movement of the car to certain Höchstbedeutung the last is displayed is information the display in a combination with the mark LIM.



The short-term announcement in probleskowom to the modes of the Höchstbedeutung institution of speed entered into memory happens also at the appendix of ignition.

If the limiter does not cope with the putting task, for example, at the movement downhill, the alarm buzzer is activated, and begins the inscription LIM to blink on the screen of the display of data.

Owing to design features of the statement of a speedometer can differ from speed limiter devices slightly.
