BMW 325xi Wagon (2001 year). Manual - part 7

84nDSC - BMW 325xi

Reactivate the DSC

Press the button again; the indicator

lamp goes out.

The laws of physics cannot be

repealed, even with DSC. It will

always be the driver's responsibility to

drive in a manner that matches road

conditions. We therefore urge you to

avoid using the additional safety margin

of the system as an excuse for taking

risks.

Whenever the DSC has been switched

off, it will not perform any stabilizing

intervention.

Do not make any changes to the DSC.

Allow only authorized technicians to

perform service procedures on the

DSC.<

For additional information concerning

DSC, please refer to "Advanced tech-

nology" on page 171.
