2.4.3. Tempostat

Use темпостата at intense movement (for example, in the city), on slippery and twisting roads, and also in other road situations which can compel to change speed, can lead to control loss over driving. In order to avoid casual activation темпостата do not leave it included if it is not used.

Tempostat is intended for maintenance of constant speed of the car (not lower 30 km/h) needlessly to hold a foot on a gas pedal (if the engine can provide it).
Management the tempostaty is carried out by means of the buttons located on the right side of a steering wheel.


  1. For activation темпостата establish a key in the ignition lock in situation "1" or "2" and press the button 4 – the activation indicator темпостата (will turn on see. Section Combination of devices).
  2. For deactivation темпостата after cancellation of maintenance of the established speed press the button 4 – the indicator in a combination of devices will be switched off. Deactivation темпостата occurs also at ignition switching off.
  3. For installation of constant speed of movement activate темпостат, disperse the car till demanded speed (not less than 30 km/h) and quickly press the button 1. Now the foot from a pedal of gas can be cleaned. By each subsequent short-term pressing the button 1 constant speed will increase by 1 km/h. If to hold the button 1 pressed, the car will be dispersed and when the button will be released, the current speed will be established as a constant.

On abrupt liftings/descents when using темпостата the car can reduce/increase speed.

  1. For temporary increase in speed (for example, when overtaking) press a gas pedal; after an otpuskaniye of a pedal of gas earlier chosen constant speed will automatically be established.

Earlier chosen constant speed is not restored, if it was exceeded for a long time.

  1. For reduction of the current established speed use the button 2: by each single pressing the established speed decreases by 1 km/h, and at button deduction speed decreases continuously and is established as a constant at a button otpuskaniye.
  2. For cancellation of maintenance of the established speed press the button 4 – the indicator thus does not die away and if necessary it is possible to return to established before speed (see below). Besides, cancellation of maintenance of the established speed occurs automatically at:
  3. Pressing a brake pedal;
  4. Moving of the lever of the AT selector from situation "D" in the situation "N";
  5. At long excess or understating of the established speed.
  6. For return to established earlier constant speed after its cancellation press the button 3.
