Traction Control
Warning: It is always the drivers responsibility
to drive safely according to the law and with due
regard to prevailing conditions.
Warning: Traction control must never let the
driver be tempted into taking risks which could
affect his or her safety or that of other road users.
Warning: Traction control cannot overcome
consequences of applying too much engine power
for prevailing conditions.
Traction control is a function of DSC, and is operated
in association with the DSC system. Traction control
prevents excessive wheel spin at standing starts, or
during acceleration. Wheel spin is usually caused by
excessive use of the accelerator pedal, or slippery,
loose or bumpy road surfaces.
To prevent excessive wheel spin and maintain vehicle
stability in such situations the traction control system
will:
• Brake either of the driven wheels when they start to
slip
• And, or, adapt the engine torque to a level
corresponding to the traction available on the road
surface
