Electronic stability control (ESC)
Electronic stability control (ESC) monitors
driving stability and traction between the
tyres and the road surface.
Electronic stability control detects when a
wheel starts to spin or the vehicle starts to
skid and stabilises the vehicle by braking
individual wheels, and/or limiting the engine
power output. This also assists when pulling
away on wet or slippery road surfaces and
stabilises the vehicle when braking.
NOTE: Electronic stability control only
functions properly if wheels with the
recommended specification tyres are
used.
Electronic stability control is activated
automatically as soon as the engine is
started.
WARNING: If the electronic stability
control warning illuminates, do not
deactivate electronic stability
control. Adapt your driving style to
suit road and traffic conditions.
Traction control system
The traction control system is an integral
part of electronic stability control.
The traction control system reduces engine
torque to prevent the wheels from spinning.
If additional intervention is required to stop
the wheels from spinning, the vehicle will
apply the rear brakes individually. The
traction control system brakes individual
drive wheels to prevent them from spinning.
This means that the vehicle can accelerate
on slippery surfaces.
WARNING: The traction control
system cannot reduce the risk of an
accident if you drive too fast.
Deactivating electronic stability control
(ESC)
WARNING: When electronic stability
control is deactivated, the risk of the
vehicle skidding is increased. Adapt
your driving style to suit road and
traffic conditions.
WARNING: Do not deactivate
electronic stability control unless on
a track and prevailing conditions are
suitable.
NOTE: When you deactivate electronic
stability control, the following
conditions result:
•
The ‘ESC OFF’ warning light illuminates
•
The light on the 'ESC OFF' button
illuminates
•
Electronic stability control no longer
improves driving stability
•
The engine’s torque is no longer
limited and the drive wheels could spin
•
The anti-lock braking system remains
activated
Electronic stability control (ESC) Dynamic
modes
The level of electronic stability control can
be adjusted to various dynamic modes to
suit the driver’s requirements and is
dependent on the handling mode currently
active.
Electronic stability control Dynamic modes
can be selected at any vehicle speed.
Ensure Sport or Track handling mode is
active, see Handling control, page 2.23.
