Engine drag control
Engine drag control (EDC

) 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*

Trailer Stability Assist (TSA
5
) 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.

Electronic Stability Control Sport
mode
The ESC
6
system is always activated and can-
not be switched off. However, the driver can
select
ESC Sport Mode, which offers more
active driving characteristics.
With the ESC Sport Mode sub-function
selected, intervention from ESC is reduced and
more lateral movement is permitted, giving the
driver more control of the vehicle than usual.
When
ESC Sport Mode is selected, ESC may
seem to be disabled even though the function
continues to assist the driver.
NOTE
When the ESC Sport Mode function is
selected, the trailer stabilizer (TSA
7
) is
switched off.
ESC Sport Mode also helps provide maximum
traction if the vehicle gets stuck or is driving on a
loose surface such as deep snow or loose sand.
