Control
The Roll Stability Control (RSC 1
) system helps
minimize the risk of a rollover in the event of e.g.
a sudden evasive maneuver or if the vehicle
begins to skid.
The RSC system monitors the lateral angle at
which the vehicle is leaning and registers any
changes. Using this information, the system cal-
culates the likelihood of a rollover. If there is an
imminent risk of a rollover, Electronic Stability
Control is activated, engine torque is reduced and
brakes are applied to one or more of the wheels
until the vehicle has regained stability.

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.

Electronic Stability Control Sport
mode
The ESC 7
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 8
) 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.

The Automatic Speed Limiter (ASL) function
helps the driver adapt the vehicle's maximum
speed to the posted speed limits.
The Speed Limiter (SL 18

WARNING

The ASL function is supplementary driver
support intended to facilitate driving and
help make it safer – it cannot handle all
situations in all traffic, weather and road
conditions.
Even if the driver can clearly see the
speed limit sign, the speed information
from the Road Sign Information (RSI)
function to ASL may be incorrect. In such
cases, the driver must intervene and
accelerate or brake to an appropriate
speed.
ASL 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.
