The AWD control unit has found a fault or the coupling has overheated: the car may drive on one axle only. The same symbol in green just means 4WD is engaged.
AWD/4WD faultYellow light · Don’t put off the repair
Tap the light to turn it on or off, just like on the dashboard.
What you can do yourself
Don’t spin the wheels. Stop, let the coupling cool for 10–15 minutes and restart.
Check that all four tires match: different sizes or uneven wear upset the drive system.
If it stays on, it needs a diagnosis: common culprits are a wheel speed sensor, the coupling or the mode switch.
The description comes from the AvtoElektrik PRO app.
OOleg’s tip: the colour of the symbol tells you how urgent it is
Red — stop and deal with the problem urgently: driving on is dangerous.
Yellow — needs checking to see what it is: don’t put off the diagnosis.
Green and blue — a system is simply working.
Exception — symbols of extra functions you switched on yourself: the rear fog light, ESP OFF by the button, heating, the differential lock. They can be yellow, but that’s not a fault — ignore them.
For example: a red oil pressure or overheating light — stop straight away and switch the engine off. A yellow Check Engine light with the engine running smoothly — drive on and get a diagnosis.
