Control systems of speed (темпостат) and Speedtronic

General information

The control system of speed (темпостат) enters into a standard complete set of considered models. The system allows to support automatically the chosen cruiser speed of movement of the car without impact on a gas pedal. Value of cruiser speed should be not lower than 40 km/h. Application темпостата becomes especially convenient at long movement on the low-loaded direct country highways. For the purpose of safety it is not recommended to include темпостат at movement in the city, on twisting, abounding with turns, to roads, on a slippery paving, in a heavy rain and at other adverse weather conditions. In the cases listed above the driver should have possibility completely to supervise a mode of movement of the car.

Misuse темпостата can be at the bottom of a road accident! Include a control system of speed only at movement on free highways and under favorable weather conditions.

During functioning of system there can be an automatic moving of a pedal of gas which thus should not be held a foot in order to avoid damage of basic and axial mechanisms!

The lever switch of management темпостата is located functioning at the left on a steering column, assemblies of the combined podrulevy switch are higher.

inclusion/switching off of system is made by means of the equipped built-in control lamp of the button of the main switch темпостата and accompanied by operation of the corresponding control lamp on the car dashboard.

Management of functioning темпостата

Tempostat of a standard design

The switch of management темпостата is located functioning on the right on a steering column

1 — Input of the current value of speed in memory of system (quickly to wring out the lever) / increase of speed (to hold the lever wrung out)
2 — Input of the current value of speed in memory of system (quickly to wring out the lever) / decrease in speed (to hold the lever wrung out)
3 — Switching off (cruiser value of speed remains in memory of system)
4 — the Call of value of cruiser speed from memory of system

The switch design темпостата allows to enter into memory of system as cruiser any current speed of the car if it exceeds value in 40 km/h, - rather quickly to wring out the lever up or down. After input of cruiser speed release a gas pedal.

Increase and fall of value of cruiser speed is made by a lever otzhimaniye up/down respectively.

Short-term acceleration of the car, for example at overtaking commission, can be made by a way of squeezing of a pedal of gas, - after a pedal otpuskaniye speed will automatically decrease to brought in memory темпостата cruiser value.

After car dispersal till the speed 40 km/h brought in memory темпостата are higher cruiser speed can be caused by a way of short-term procrastination of the lever on itself.

Activate a call of cruiser speed from memory of system only if know its value and are ready to movement with it.

At movement with included tempostaty under a bias and uphill there can be deviations from the set cruiser value of speed.

At a key povorachivaniye in the ignition lock in situation 1 or 0 there is a dumping brought in memory темпостата cruiser value.

Tempostat with the limiter of speed

Order of using the switch темпостата with the limiter of speed


1 — Increase in speed 2 — Turning on/activation of the limiter 3 — Switching off 4 — Reduction of speed

Inclusion темпостата is made by an otzhimaniye of the lever of the switch down.

The functioning principle темпостата in a normal mode is similar described above for standard systems.

At the current speed of movement below 35 km/h the design темпостата allows to enter restriction of a high-speed mode with input into memory темпостата values of speed admissible limit in 30 km/h. For activation of the limiter of speed it is necessary to delay also the switch lever down, - on the screen of the display value of 30 km/h is highlighted.

At movement under a bias the current speed can exceed some limiting admissible value (30 km/h).

Speedtronic system

Order of using the switch темпостата on the models equipped with Speedtronic system

1 — limiter Activation speed/increase of value of cruiser speed with a step in 10 km/h
2 — limiter Activation speed/fall of value of cruiser speed with a step in 10 km/h
3 — Switching off of the limiter of speed
4 — the Call of the value of restriction of speed brought in memory / thin adjustment of speed with a step to 1 km/h
5 — Switching of modes tempostat/Speedtronic

The Speedtronic system is темпостат with variable and constant limiters of speed.

The switch of management allows to be switched by Podruleva from a mode темпостата in a mode of restriction of speeds with change of own functions. Switching is made by pressing a face part of the handle of the lever of the switch.

In a mode темпостата instructions for use the switch are similar described above for standard systems.

Variable limiter of speed

The variable limiter of speed allows not to exceed at the expense of restriction of turns of the engine some threshold of speed, for example, in need of observance of traffic regulations.

Do not forget that responsibility for excess of a high-speed mode is born always by the driver!

Activation of a mode of variable restriction of a high-speed mode is made by pressing a face part of the handle of the lever of the switch темпостата and accompanied by operation of the yellow LIM indicator on the handle, the similar inscription is highlighted on the display screen.

The limiter is activated only provided that the current speed of movement of the car differs from brought in memory of system of limiting value no more than on 30 km/h.

Change of value of speed limit is made by an otzhimaniye of the lever of the switch up or down. The chosen value is displayed the information display. At the working engine input of any restriction of a high-speed mode, since value of 30 km/h is possible.

The established limit of speed can be exceeded only when squeezing a pedal of gas against the stop (kickdown mode inclusion).

The exit from a mode of restriction can be made by a way of a short-term otzhimaniye of the lever from itself, or in pressing an end face of its handle, - indication of LIM should disappear from the display screen. Automatic shutdown of the limiter occurs at car dispersal in the kickdown mode till the speed exceeding limiting value more than on 20 km/h.

If the limiter does not cope with an objective, for example, at movement downhill, the alarm buzzer is activated, and LIM inscription on the screen of the information display starts to blink.

Owing to design features of the indication of a speedometer can slightly differ from installations of the limiter of speed.

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

Constant limiter of speed

By means of the constant limiter the maximum speed of movement of the car can be limited, for example, at its operation with winter tires.

Restriction can be established in a range from 190 km/h till speed possible limit of movement of the car. The established continuous restriction of speed continues to operate and in case of activation of variable restriction.

For activation of a mode press a face part of the switch. the lever of the AT selector transfer to the situation "R", and a key in the ignition lock - in situation 2 (the engine do not start). Then, having waited for about a second, pull the lever on itself, - on the screen of the display value of speed will be highlighted. At a lever otpuskaniye indication will start to blink, - installation of speed is made by lever procrastination up or down. Input of the chosen value in memory of system is made by lever procrastination on itself, - the confirming sound signal should be distributed.
Installation dumping can be in case of need made, - increase entered value until on the screen the threefold dash (----) will not be highlighted, then pull the lever on itself to a sound signal.

At approach of the current speed of movement of the car to the established limiting value the last is displayed information the display in a combination to LIM mark.

Short-term indication in a flashing mode of the device of limiting value of speed entered into memory occurs also at ignition inclusion.

If the limiter does not cope with an objective, for example, at movement downhill, the alarm buzzer is activated, and LIM inscription on the screen of the information display starts to blink.

Owing to design features of the indication of a speedometer can slightly differ from installations of the limiter of speed.
