This considerablyimproves the driving stability of thevehicle on slippery road surfaces.TC is operational after each enginestart as soon as the control indicatorb extinguishes.When TC operates b flashes.9 WarningDo not let this special safetyfeature tempt you into taking riskswhen driving.Adapt speed to the roadconditions.Control indicator b 3 87.DeactivationTC can be switched off when spinningof drive wheels is required:press button t briefly to deactivateTC, k illuminates. Deactivation isdisplayed as status message in theDriver Information Centre.TC is reactivated by pressing the tbutton again.TC is also reactivated the next timethe ignition is switched on.Electronic Stability ControlElectronic Stability Control (ESC)improves driving stability whennecessary, regardless of the type ofroad surface or tyre grip.
