WARNING
The Electronic Stability Control system
ESC is supplementary driver support
intended to facilitate driving and make it
safer – it cannot handle all situations in
all traffic, weather and road conditions.
ESC is not a substitute for the driver's
attention and judgment. The driver is
always responsible for ensuring the vehi-
cle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.
Stability control 3This function helps control the driving and brak-
ing force of each individual wheel in an attempt
to stabilize the vehicle.
Spin control and active yaw controlThis function is active at low speeds and brakes
the wheels that are spinning to transfer additional
power from wheels that are not spinning.
This function also helps prevent the wheels from
spinning while the vehicle is accelerating.
Engine drag control
Engine drag control (EDC
4
) helps prevent inad-
vertent wheel lock, e.g. after downshifting or
using engine braking when driving at low speeds
on a slippery surface.
Inadvertent wheel lock while driving could impair
the driver's ability to steer the vehicle.
Trailer Stability Assist* 5
Trailer Stability Assist (TSA
6
) is designed to help
stabilize a vehicle that is towing a trailer if the
vehicle and trailer have begun to sway. For more
information, see "Trailer Stability Assist".
NOTE The TSA function is deactivated if
ESC Sport
Mode is activated.

above or below the posted speed limit. For exam-
