Pilot lamps
Control lamps are located in different parts of the instrument panel. Pilot lamps can be divided into two groups: self-controlled and externally controlled.
The activation of the self-controlled indicator lamps depends on the instrument panel software logic.
The instrument cluster software controls the activation of warning lamps when the ignition is turned on, as well as all warning lamps controlled by the instrument cluster, such as the low fuel warning lamp.
Externally controlled indicator lamps are powered by the control module of another system or are switched on by the instrument panel when receiving a bus message from a module in another subsystem.
Some indicator lamps are switched on by the external subsystem module, but instrument cluster control logic is applied. These indicator lamps are listed in the following table with the type of control.
The table also indicates which warning lamps are present and which of the warning lamps come on when the ignition is switched on and the type of control (external or internal).

The following describes the functional purpose of each control lamp listed above. The activation of some warning lamps is accompanied by an audible signal from the instrument panel buzzer, as well as a corresponding message on the message center display on the upgraded instrument panels. Some indicator lamps are only found on standard instrument clusters, while upgraded instrument clusters replace indicator lamps with messages.
1. Air suspension warning light
The air suspension warning light is controlled by the instrument cluster software when it receives a CAN bus signal from the air suspension control module. The air suspension control module sends a number of different signals about the operation of the air suspension system. The instrument panel interprets these signals and, depending on these signals, turns on the orange or red indicator light. To alert the driver, some signals are accompanied by a request to sound the horn on the instrument panel buzzer.
2. Transfer case low range warning light
The transfer case low range warning light is controlled by the instrument cluster software when it receives CAN bus signals from the transfer case control module. During high to low range switching, the control lamp flashes green. When the changeover is completed, the low range indicator lamp remains lit until the high range is selected.
In addition, the transfer case control module sends a single chirp request to the instrument cluster to notify the driver that the shift to the selected range is complete. On upgraded instrument clusters, range switching information is also shown in the message center display.
3. Control lamp for turning on the system of automatic stability control on the descent (HDC)
The HDC ON indicator light is controlled by the instrument cluster software when it receives CAN bus signals from the ABS module. The warning lamp illuminates green when the HDC system is on and the vehicle speed is below a preset threshold. If the vehicle speed exceeds a preset threshold, the warning lamp flashes until the vehicle speed decreases. On high-end instrument clusters, a message is shown in the message center display. For more information refer to AntiLock Control - Traction Control (206-09A Anti-Lock Control - Traction Control)
If the temperature of the brake discs exceeds a preset value as a result of the HDC system, the HDC system will begin to reduce braking performance. The HDC Warning Light flashes during deceleration and, on upgraded instrument clusters, the message center display shows a message to that effect. After the discs have cooled to an acceptable temperature, the HDC system turns on again and the HDC system indicator lamp is on constantly.
4. Control lamp for dynamic stability control (DSC) / traction control
The DSC/Traction Control warning light is controlled by the instrument cluster software when it receives CAN bus signals from the ABS module. When checking the lamps when the ignition is switched on, the control lamp lights up in orange for 3 seconds. If no faults are found, the control lamp goes out after the lamp test is completed.
When the DSC system is on, the warning light flashes to notify the driver that the system is adjusting engine output and braking force. If the warning light stays on after checking the bulbs or while driving, the DSC system is faulty or has been disabled by the driver using the DSC switch on the instrument panel.
5. Ignition/lack of charge warning light
The ignition/lack of charge warning light is controlled by the instrument cluster software when it receives CAN bus signals from the engine control module (ECM). The control lamp lights up red when the ignition key is in position II and goes out when the engine is started.
If the warning light stays on after the engine is started or stays on while the vehicle is moving, the alternator is defective.
6. Low oil pressure warning light
The low oil pressure warning light is directly wired to the instrument panel. The control lamp lights up red when the ignition key is in position II. After starting the engine or increasing the oil pressure, the control lamp should turn off. If the warning light stays on after starting the engine, or stays on while the vehicle is moving, the vehicle must be stopped as soon as possible and the engine must be turned off and not restarted until the problem has been rectified.
7. Control lamp for turning on glow plugs (only for models with diesel engines)
The glow plug warning light is controlled by the instrument cluster software when it receives a CAN bus signal from the engine control module (ECM). The warning light is located in the same location on the instrument panel as the MIL warning light on petrol models. When the ignition key is turned to position II, the control lamp lights up orange. The duration of the indicator lamp on depends on the engine temperature, and in some cases, when the engine temperature is high, it does not turn on at all. Turning on of the warning lamp depends on the signals transmitted by the ECM on the CAN bus, the duration of which is determined by the duration of the power supply to the glow plugs to warm up the combustion chambers. For more information refer to Glow Plug System (303-07C Glow Plug System)
At the end of the heating of the glow plugs, the control lamp goes out, informing the driver that the engine can be started.
8. Malfunction indicator lamp (MIL)
The MIL is controlled by the instrument cluster software when it receives CAN bus signals from the ECM. The warning lamp comes on during the lamp test performed by the ECM when the ignition key is turned to position II. The control lamp turns off after starting the engine.
If the warning light stays on after the engine is started or stays on while the vehicle is moving, this means there is a problem with the system that needs to be fixed as soon as possible. Turning on the MIL warning lamp indicates a malfunction of the on-board diagnostic system (OBD), which leads to an increase in the toxicity of exhaust gases. The cause may be a malfunction of the engine control system or transmission.
9. Control lamp of additional security system (SRS)
The SRS warning light is controlled by the Supplemental Safety System Module, which sends CAN signals to the instrument cluster. The warning lamp illuminates for 6 seconds during the lamp test performed by the additional security system control module when the ignition key is turned to position II. If a malfunction is detected in the SRS system, the Supplemental Security System Control Module illuminates a red warning light until the malfunction is corrected.
The instrument panel also checks the operation of the indicator lamp LED. To notify the driver of a faulty indicator lamp LED, the odometer display shows the message "5R5" (SRS).
10 and 11. Control lamps of indexes of the left and right turn
The turn signal lamps are controlled by the instrument cluster software when signals are received via the medium speed CAN bus from the central distribution unit (CJB). When the direction indicator is turned on, the CJB sends a command to the instrument panel to turn on the indicator lamp for the corresponding turn. The instrument cluster software controls the flashing frequency of the flashing green warning light. If the direction indicators are working properly, the flashing of the control lamps is slow and is accompanied by an audible signal emitted by the instrument panel warning light. If there is a malfunction in the system, when a message is received from the CJB, the instrument panel doubles the flashing frequency of the indicator lamps.
The hazard warning lamp is also controlled by the CJB and the instrument cluster software and operates in the same way as the turn signal lamps. The hazard warning lights can work with the ignition off, so a signal to the instrument cluster via the cAn bus from the CJB that turns on both turn signal lights also wakes up the instrument cluster.
12. High beam warning lamp
The high beam warning lamp is controlled by the instrument cluster software when it receives signals via the medium speed CAN bus from the central distribution unit (CJB). When the high beam switch is moved to the high beam position or the high beam flash position, the CJB sends a CAN·message to the instrument cluster to turn on the high beam indicator lamp blue.
13. Tire pressure warning light (TPMS):
Tire pressure warning light (TPMS) controlled by the instrument panel software when receiving CAN bus signals from the TPMS module. The indicator lamp illuminates orange for 3 seconds during the lamp test performed by the TPMS module when the ignition key is turned to position II. If the warning light stays on after starting the engine or stays on while the vehicle is moving, the TPMS module has detected a problem. Tire pressures must be manually checked until the problem is corrected.
14. Seat belt warning lamp
The seat belt warning lamp is controlled by the Supplemental Restraint Control Module and instrument cluster software when it receives CAN bus signals from the Supplementary Restraint Control Module.
The control lamp lights up red when the ignition key is in position II. The indicator lamp stays on until the seat belt is fastened. If the seat belt of the occupied front seat is not fastened and the vehicle speed exceeds 8 km/h, the control lamp flashes and an intermittent sound signal from the instrument panel buzzer sounds for 10 seconds. This warning repeats every 30 seconds until the seat belt is fastened, the vehicle speed drops below 5 km/h or the ignition is switched off.
On vehicles for North American countries, the warning lamp stays on until the seat belt is fastened, the vehicle speed drops below 5 km/h or the ignition is switched off.
15 and 38. Brake warning lamp
This warning lamp is controlled by CAN bus signals from the ABS module and indicates malfunctions of the emergency brake assist system (EBA) or electronic brake force distribution (EBD). Monitoring of brake pad wear and brake fluid level is carried out by the instrument panel, which has a wired connection to brake pad wear and brake fluid level sensors.
Depending on the nature of the fault, the control lamp lights up yellow or red. The control lamp joins at check of lamps at inclusion of ignition. The control lamp lights up orange for 1.5 seconds and red for another 1.5 seconds. If no faults are found, the control lamp goes out after the lamp test is completed.
Each function of the brake warning light has been assigned a priority. Faults that require the warning lamp to glow red have higher priority than malfunctions that require the lamp to glow orange.
Brake pad wear
Front left inner pad and rear right inner pad are equipped with wear sensors. Pad wear sensors are connected in series with the instrument panel, which constantly monitors these circuits. When the wear of one or both pads reaches the permissible limit (approximately 75%), the pad wear sensor circuit is broken and this is determined by the instrument panel software. The instrument cluster illuminates the brake warning light in red, and on advanced instrument clusters, the message center display shows the message "CHECK BRAKE PADS" (check brake pads). After replacing the pads, the instrument panel detects a shorted circuit and cancels the warning lamp and message (if applicable) when the ignition key is turned to position II.
Warning about malfunctions of EBA/EBD systems
If a malfunction occurs in the EBA or EBD systems, the ABS module sends a signal to the instrument cluster via the CAN bus. The instrument cluster software illuminates the brake system warning lamp in orange for minor faults in the eBa/EBD systems or in red for major faults in these systems. The control lamp continues to burn until the malfunction is eliminated.
Low brake fluid
A sensor is installed in the brake fluid reservoir, which is directly connected to the instrument panel. When the ignition key is turned to position II, the fluid level is checked. To avoid erroneous warnings while the vehicle is moving, the sensor is monitored every 25 seconds. When the brake fluid level is low, the instrument cluster illuminates the brake system warning light in red, and on advanced instrument clusters, the message center display shows the message "CHECK BRAKE FLUID" (check the brake fluid level). Turning on the low brake fluid warning light is accompanied by an audible instrument panel buzzer.
16. Anti-lock braking system warning lamp (ABS)
The ABS warning lamp is controlled by the ABS module, which sends CAN signals to the instrument cluster. The indicator lamp lights up orange for 3 seconds during the lamp test performed by the ABS module when the ignition key is turned to position II. If the warning lamp stays on after the engine is started, or if it stays on while the vehicle is moving, this means that there is a problem with the ABS system and it is not possible to perform system functions.
If during the bulb test, the warning light comes on for 0.5 seconds, turns off for 0.5 seconds, and then stays on for the remaining two seconds of bulb test mode, this indicates a stored fault in the ABS module memory.
If the warning lamp comes on due to a faulty sensor, it will continue to light the next time the ignition is switched on, even after the fault has been rectified. The warning lamp will turn off when the vehicle speed exceeds 20 km/h. This allows the ABS module to perform a thorough check of the system and validate the outputs of the replaced sensor.
17. Cruise control warning light
The cruise control warning light is controlled by the ECM and instrument cluster software when it receives CAN bus signals from the ECM. The indicator lamp illuminates when the cruise control system has been resumed and the current speed differs from the set speed by no more than 8 km/h, or that the cruise control system is on and the current speed is maintained within 8 km/h of the set speed.
18. Control lamp of the adaptive system of front lighting devices (AFS)

For more information refer to Anti-Lock Control -Traction Control (206-09A Anti-Lock Control - Traction Control)
If during the bulb test, the warning light comes on for 0.5 seconds, turns off for 0.5 seconds, and then stays on for the remaining two seconds of bulb test mode, this indicates a stored fault in the ABS module memory.
If the control lamp turned on due to a sensor malfunction, then it continues to burn even the next time the ignition is turned on, even after the malfunction has been eliminated. The warning lamp will turn off when the vehicle speed exceeds 20 km/h. This allows the ABS module to perform a thorough check of the system and validate the outputs of the replaced sensor.
If, as a result of the HDC system, the temperature of the brake discs exceeds a preset value, the HDC system will begin to reduce braking performance. The HDC system malfunction indicator lamp flashes during deceleration.
