DSC* BMW 316i, 318i, 320i, 323i, 330i, 318d, 320d, 330d
The principle
Dynamic Stability Control DSC is designed to maintain driving stability in critical situations.
The DSC system is in operation when- ever the engine has been started. DSC incorporates the functions of Dynamic Traction Control DTC and Cornering Brake Control CBC. You will find further details on DSC in the "Technical items of interest" bro- chure.
Telltale light
The telltale light in the instru- ment cluster goes out shortly after the ignition is switched on, see page 19.
If the telltale light flashes:
DSC is controlling drive and braking forces.
If the telltale light remains permanently on:
DSC has been switched off at the but- ton; DTC and DBC are ready.
There is no indicator to show when DTC is in action.
The telltale light and the brake warning light remain perma- nently yellow:
DSC, DTC and DBC have been switched off at the button, or are defective.
Note, however, that the vehicle remains operational without DSC. If a fault develops you should consult BMW Service as soon as possible.
Deactivating DSC/activating DTC
Briefly press the DSC button: the tell- tale light remains permanently on. DSC is deactivated; DTC is ready. In the following exceptional situations it may be best to activate DTC for a short time:
>If the car has to be rocked out of a
hollow or a soft surface, or started in deep snow or on a loose surface
>If you are driving on snow-covered
gradients, in deep snow, or on hard- packed snow
>If snow chains are fitted.
Traction is boosted by reducing the sta- bilising influences. Ov ervi ew Contr ol s M ai nt enan ce M in or repai rs Da ta or ds

Deactivating DSC and DTC
Press and hold down the DSC button for at least 3 seconds; the telltale light and the yellow brake warning light remain permanently on.
Under these circumstances no stability- or traction-improving manipulation of engine or brakes takes place.
In order to maintain maximum driving stability, you should drive with the DSC system activated when-
ever possible.<
Reactivating DSC
Briefly press the button a second time; the telltale light or lights go out.
Not even DSC can overcome the laws of physics. The driver is always responsible for matching his or her style of driving to the prevailing
conditions. The extra safety potential offered by this system must never be understood as an invitation to take additional risks.
When DTC is in ready mode DSC is deactivated and DTC contributes to a limited extent to stabilising the car. Make no modifications to the DSC sys- tem. All work on the DSC should be entrusted only to skilled, authorised
personnel.<

hollow or a soft surface, or started in deep snow or on a loose surface
>If snow chains are fitted.
