The ESP supports stability when the
vehicle starts to slide away from your
intended path. This is performed by braking
individual wheels and reducing engine
torque as needed.
The system also provides an enhanced
traction control function by reducing
engine torque and braking if the wheels
spin when you accelerate. This improves
your ability to pull away on slippery roads
or loose surfaces, and improves comfort
by limiting wheel spin in hairpin bends.

Stability control (ESP) warning lamp
The ESP warning lamp will flash when the
system is operating. See Warning Lamps
and Indicators (page 56).
Emergency brake assist
WARNING
Emergency brake assist does not
relieve you of your responsibility to
drive with due care and attention.
Emergency brake assist will detect when
you brake heavily by measuring the rate at
which you press the brake pedal. It will
provide maximum braking efficiency as
long as you press the pedal. Emergency
brake assist can reduce stopping distances
in critical situations.
Trailer stability control
WARNINGS
Trailer stability control does not
relieve you of your responsibility to
tow with due care and attention.
Disabling ESP will turn off the
system.
Trailer stability control is an enhanced
feature of ESP, and automatically detects
when an attached trailer starts to sway.
If this situation occurs, the system will
automatically brake individual wheels to
stabilise the trailer and vehicle. In case a
very severe sway is detected, the engine
torque will be reduced and the vehicle will
be slowed automatically.

USING STABILITY CONTROL

Note: The system will be switched on
automatically every time you switch the
ignition on.
