Traction control system
Drivers should never take
unnecessary risks even
though the Traction Control
System offers inherently safer
driving potential.
Principle of operation
BTCS/TCS indicator light
The Traction Control System
reduces wheel spin at the driven
wheels.
108
The system may become active
when accelerating on a slippery
road or loose surface, or when
pulling away on a hill.
Two different types of Traction
Control System are available with
this model range.
Brake Traction Control System
(BTCS)
(1.4 l Zetec-SE and diesel
engines)
This system minimises cross-axle
wheel slip to enhance traction at
lower speeds.
Traction Control System (TCS)
(1.6 l Zetec-SE, 1.8 l Zetec-E,
2.0 l Zetec-E and
2.0 l Duratec-ST engines)
This system controls wheel slip on
the drive axle by a combination of
engine torque reduction and brake
control (BTCS) to enhance vehicle
stability, steerability and traction at
all vehicle speeds.
