DRIVER SUPPORT
* Option/accessory.
288
Spin control and traction control
system
The function is active at low speed and brakes
the drive wheels that spin so that additional
traction shall be transferred to the drive
wheels that are not spinning.
The function can also prevent the driving
wheels from spinning against the road surface
during acceleration.
Engine Drag Control
Engine Drag Control (EDC
3
) can prevent invol-
untary wheel locking, e.g. after shifting down
or engine braking when driving in low gear on
slippery road surfaces.
Involuntary wheel locking while driving can,
amongst other things, impair the driver's abil-
ity to steer the car.
Trailer stability assist*

Trailer stability assist (TSA
5
) stabilises a car
towing a trailer in situations where they begin
snaking.
NOTE
Trailer Stability Assist is deactivated if ESC
Sport Mode
is activated.

Electronic Stability Control in sport
mode
The stability system (ESC
6
) is always acti-
vated – it cannot be switched off. However,
the driver can select
ESC Sport Mode,
which allows for a more active driving experi-
ence.
With the ESC Sport Mode subfunction
selected, intervention from the system is
reduced and the car is allowed to skid more
and greater control than normal is thus trans-
ferred to the driver.
When
ESC Sport Mode is selected, the func-
tion can be considered as deactivated, despite
the function continuing to help the driver in
many cases.
NOTE
With ESC Sport Mode selected, Trailer
Stability Assist (TSA
7
) is deactivated.
ESC Sport Mode also provides more traction
even if the car has become bogged down or is
driving on a loose surface, such as in sand or
deep snow.
