System cruise control


Cruise control represents possibility to remember and support any speed of movement of a constant, beginning from about 40 km/h to the almost maximum.

Management cruise control is carried out by the lever close to the lever of the multipurpose switch.

Cruise control should not be included, if movement with constant speed (for example, a dense transport stream, plentiful turns, the slippery or dirty road) is inexpedient.

In case of an automatic transmission inclusion cruise control is meaningful only at a step of D.

1–For acceleration fixing quickly move the switch.

2–For delay fixing кратковре menno move the switch.

Short-term installation of the switch in situation 1 or 2 fixes speed of the car. The pedal of an accelerator can be released.

For increase or reduction of speed of the car move the lever to situation 1 or 2 and hold him in this situation, demanded speed will not be reached yet. At repeated moving of the lever new speed will be fixed.

At short-term moving of the lever to situation 1 or 2 there is a step-by-step increase of speed of movement on 1 km/h without pressing an accelerator pedal.

3–Switching off.

For system switching off cruise control quickly establish the lever in situation 3.

The system cruise control is switched off also in the following cases:

 – speed of movement is lower than 40 km/h or
 – the pedal of a brake is pressed or
 – the pedal of coupling is pressed or
 – the control lever is established by an automatic transmission in situation N.

4–Storing of speed of movement.

At speed of the car over 40 km/h storing of speed is made by short-term moving of the lever to situation 4.

The speed of movement brought in memory after switching off of ignition is erased.


Car acceleration by pressing an accelerator pedal is possible. After an otpuskaniye of a pedal of an accelerator the speed of movement of the car written down in memory is established before.
