Dynamic Torque Vectoring (DTV)
Dynamic Torque Vectoring (DTV) uses input signals such as
speed, acceleration and steering angle to monitor vehicle
behaviour during cornering. A small amount of brake pressure
will then be applied to the inside rear wheel to reduce
understeer. DTV is always active, but is more responsive when
the ESP is set to either Track or OFF.

Driving
Traction Control System (TCS)
The Traction Control System (TCS) is a function of ESP and is used
to prevent 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.
Warning: It is always the drivers responsibility to drive
safely according to the law and with due regard to prevailing
conditions.
Warning: Traction control cannot overcome the
consequences of applying too much engine power for
conditions, and must never let the driver be tempted into
taking risks which could affect their safety or that of other
road users.
To prevent 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.
• Adapt the engine torque to a level corresponding to the
traction available on the road surface.
These symptoms are normal and will clear as wheel spin is
eliminated and normal engine power is restored.
If cruise control is on it will automatically go OFF when ESP is
operating.
If traction control operates when driving on extended icy or
slippery surfaces, reduce engine power as necessary until the ESP
warning symbol goes OFF.
