The STC/DSTC button
The STC/DSTC button in the center control panel (see
page 31
) is used to switch the Spin Control (SC)
function on or off.
NOTE: AYC (on models equipped with this function) will also be reduced, but not switched off, if SC
is switched off.
The button must be pressed for at least a half second to prevent SC from being switched off
inadvertently.
When the function has been switched off, the green indicator lamp in the button will go out and "STC/
DSTC SPIN CONTROL OFF" will be displayed in the text window.
All STC/DSTC functions are (re)activated each time the engine is started.
The Stability Control indicator light
The Stability control indicator light will come on for approximately 2 seconds when the ignition is
switched on as the system performs a self-diagnostic test.
The Stability Control indicator light will flash when:
●
Traction Control is actively functioning to help avoid drive-wheel spin.
●
Spin Control is actively functioning to help avoid loss of traction during acceleration.
●
Active Yaw Control is actively functioning to help avoid skids or lateral slides.
The warning symbol in the instrument panel
A steady yellow glow indicates:
●
That the system has been automatically disengaged due to a fault. "ANTI SKID SERVICE
REQUIRED" be displayed in the text window. An authorized Volvo retailer should check the system.
●
The system has been temporarily switched off due to high brake temperature. "TRACTION
CONTROL TEMPORARILY OFF" will be displayed.
NOTE: The system will automatically switch on again when the brakes have cooled.
