Caution! If the ABS is faulty, the ESC, ASR and EDS systems will not work either. The ABS fault is indicated by the control lamp.
Electronic Stability Control (ESC)
ESC key
The ESC system improves control over the vehicle in extreme dynamic modes, for example, when changing direction abruptly. Depending on the road conditions, the risk of skidding is reduced and, thus, the vehicle's stability is increased. The ESC system is automatically activated each time the ignition is switched on.
The system monitors the steering wheel angle and vehicle speed set by the driver and constantly compares them with the actual vehicle performance. If any discrepancies are detected, such as when the vehicle starts to skid, the ESC system automatically applies the brakes to the corresponding wheel. When the system is triggered, the control lamp
blinks in the instrument cluster. The UES electronic stability control system includes the following components: anti-lock system (ABS) anti-slip system (ASR), electronic differential lock (EDS and XDS), active steering assistant (DSR), brake assistant (H8A), start-up assistant (NNS), auto-brake function in case of an accident, maintenance system road train Stability Index (TSA). The ESC system cannot be deactivated. You can only disable or configure individual systems that are built into ESC.
Turning ASR on/off
The ASR function in the ESC can be deactivated/activated in the Infotainment system or using a button.
Press the key briefly
.
The 5th control lamp in the instrument cluster lights up, and the following message appears on the display: "M" Anti-skid system (ASR) is off. "E" ASR is OFF.
Press the key again.
The control lamp in the instrument cluster goes out, the following message appears on the display: "M" Anti-skid system, ASR system is on. "5" ASR ON.
ESC Sport On/Off
The ESC Sport function within the ESC can be activated/deactivated in the infotainment system or using a button.
ESC Sport is a mode that is suitable for a sporty driving style. When ESC Sport is turned on, the ASR system is switched off. The ESC system reacts with a delay so as not to: interfere with sporty driving. Press and hold the button for a while.
The control lamp in the instrument cluster lights up, the following message appears on the display: "M". ESC Sport: limited stability. "S" ESC SPORT.
Press the key again.
The indicator lamp in the instrument cluster goes out and the following message appears on the display: "M" ESC (stability control system) enabled. "S" ESC ON.
Caution! When ESC mode is turned on, the ASR system is automatically turned off. Therefore, some other functions may operate with restrictions.

Anti-lock braking system (ABS)
ABS prevents the wheels from locking when braking. This helps the driver maintain control over the car. The adjustment process is accompanied by pulsation of the brake pedal and noise. When ABS is activated, do not perform intermittent braking or ease off the pressure on the brake pedal.
Anti-Slip Regulation (ASR)
ASR key
When the wheels slip, ASR adapts the engine speed to the road surface. When the road surface is unfavourable, ASR makes starting, accelerating and driving on inclines easier. ASR is activated automatically every time the ignition is switched on. If your vehicle is equipped with ESC, the ASR traction control system is integrated into the ESC system. When the system is activated, the ASR control lamp flashes
in the instrument cluster. As a rule, the ASR system should be constantly switched on. It is advisable to switch off the system only in the following situations: driving with anti-skid chains, driving in deep snow or on loose ground, pulling out a stuck car "rocking". The ASR system can be deactivated in the Infotainment system or using the button 
.
When ASR is disabled, the control lamp in the instrument cluster lights up
. Then ASR should be turned on again.
Electronic differential lock (EDS and XDS)
EDS
When a drive wheel slips, EDS brakes the slipping wheel and thereby transfers torque to the other drive wheels. This increases the stability and dynamics of the car. To prevent the disc brakes of the braked wheel from overheating, EDS is automatically switched off. All other car systems remain in working order as in the same car without EDS. As soon as the brake temperature drops, EDS is automatically switched on.
XDS
The XDS function is an addition to the electronic differential lock. XDS does not react to slippage, but to the unloading of the wheel of the drive axle located closer to the center of the turn at high speed in the turn. By automatically engaging the brakes of the unloaded wheel, it is prevented from slipping. This improves the traction of the wheels with the road and helps stabilize the car.
Active Steering Assist (DSR)
The DSR function provides the driver with steering recommendations to stabilise the vehicle in critical situations. The steering assistant is activated, for example, during heavy braking when the road surface under the right and left wheels is different.
Brake assistant (BA)
It increases braking efficiency and helps to reduce the braking distance. The brake assistant is activated when the brake pedal is pressed sharply. To ensure the shortest possible braking distance, the brake pedal must be pressed all the way until the car comes to a complete stop. After releasing the brake pedal, the brake assistant automatically stops. During the operation of the brake assistant, ABS works faster and more effectively.
Hill start assist (HHA)
The Hill Start Assist allows you to move your foot from the brake pedal to the gas pedal when starting off on an incline, without holding the car with the parking brake. The system maintains the pressure in the brake system for 2 seconds after releasing the brake pedal. The pressure in the brake system drops gradually as the driver presses the gas pedal. If the driver does not start off within 2 seconds, the car will begin to roll back. Hill Start Assist is activated on inclines steeper than 5%, provided that the driver's door is closed. It is activated only when starting off on an incline, both when moving forward and when reversing. It is not activated when moving downhill.
Automatic braking function in case of accident
Initiates automatic braking after a collision to reduce the risk of repeated collisions. Automatic braking can only be performed at speeds above 10 km/h, in the event of a frontal or side collision. The vehicle is braked automatically, using the ESC system, as long as the brakes, the ESC system and the necessary electrical equipment remain functional after the collision. If the driver presses the brake pedal during an accident, the automatic braking function does not operate.
