Conditions of inclusion:
- switch in the "Cruise control" position;
- 2nd gear recognized by ECU;
- speed not less than 30 km/h, not more than 200 km/h (for reference);
- the indicator light is continuously green (cruise control);
- pressing the switch "+", "-" or "restore the set speed".
Shutdown conditions:
- pressing the accelerator pedal;
- pressing the brake or clutch pedal;
- pressing the switch "0";
- switch in the "off" position;
- trajectory stabilization system intervention;
- injection ECU intervention;
- the transmission is not engaged.
When you press the accelerator pedal, the cruise control operation is temporarily disabled. When you release the accelerator pedal, the system is restored.
Note: Flashing of the set speed value indicates to the driver that maintaining the set speed is not possible.
Operating principle of the speed limiter
Conditions of inclusion:
- switch in the "Speed limiter" position;
- 2nd gear recognized by ECU;
- speed of movement not less than 30 km/h, not more than 200 km/h (for reference);
- the indicator light is continuously yellow (speed limiter);
- pressing the switch "+", "-" or "restore the set speed".
Shutdown conditions:
- sharp pressing of the accelerator pedal (overcoming resistance);
- switch in the "off" position;
- trajectory stabilization system intervention;
- injection ECU intervention;
- pressing the switch "0".
When the accelerator pedal is pressed, the system operation is temporarily prohibited.
When the accelerator pedal is released, the system's functionality is restored.
Purpose of connectors
Three-position switch:
- A1. "+" of side lights.
- A2. "+" after ignition switch (shutdown circuit).
- AZ. Turning cruise control on/off.
- 81. Switching the speed limiter on/off.
- 82. "Mass".
- 83. Not used.
Steering wheel switches
A - Resume button = resistance approximately 900 ohms.
B - Pause button = 0 Ohm resistance.
C - "+" button = resistance approximately 300 Ohm.
D - "-" button = resistance approximately 100 Ohm.

Accelerator pedal
The accelerator pedal has a safety stop.
1. "Mass" of potentiometer 2.
2. "Mass" of potentiometer 1.
3. Signal from pedal potentiometer 1.
4. Power supply for potentiometer 1.
5. Power supply for potentiometer 2.
6. Signal from pedal potentiometer 2.
The resistance of track 1 is 1200±480 0m.
Track 2 resistance = 1700±680 Ohm.
Attention! For normal operation, the vehicle must be equipped with an accelerator pedal with a stop at the middle of the stroke.
Brake pedal limit switch (dual)
Cruise control uses a normally open contact (common with brake lights), the closing contact is used by the ABS ECU.
Both signals are compared by the injection ECU.
A1. Closed contact.
A3. Break contact.
B1. Break contact.
BZ. Closing contact.
When installing the limit switch on the pedal assembly, pull the rod to select the adjustment gap.
