Electronic Stability Control (ESC)
Electronic Stability Control (ESC) helps reduce
wheel spin, counteract skidding and to generally
help improve directional stability.
A pulsating sound will be audi-
ble when the system is actively
operating and is normal. Accel-
eration may also be slightly
slower than normal.
WARNING
ESC is a supplementary aid and cannot deal
with all situations or road conditions.
The driver is always responsible for operating
the vehicle in a safe manner in accordance
with current traffic regulations.
ESC consists of the following functions:
•
Traction control
•
Spin control
•
Active Yaw Control
•
Engine Drag Control
•
Trailer Stability Assist
Traction control
This function is designed to help reduce wheel
spin by transferring power from a drive wheel that
begins to lose traction to the wheel on the oppo-
site side of the vehicle (on the same axle).
Spin control
This function is designed to help prevent the
drive wheels from spinning while the vehicle is
accelerating.
Active Yaw Control
At low speeds, this function helps maintain direc-
tional stability by braking one or more of the
wheels if the vehicle shows a tendency to skid or
slide laterally.
Engine Drag Control EDC
EDC helps keep the engine running if the wheels
show a tendency to lock, e.g., when shifting down
in the manual shifting mode or while using the
engine's braking function on a slippery surface. If
the wheels were to lock, the vehicle would
become more difficult to steer.
Trailer Stability Assist*
7
TSA helps stabilize a vehicle that is towing a
trailer when the vehicle and trailer have begun to
sway.
This system is automatically deactivated if the
driver selects Sport mode.
