Driving Stability Control Systems
even more quickly when braking in critical situa‐
tions.
Vehicle equipment
This chapter describes all standard, country-spe‐
cific and optional equipment available for the
model series. It may therefore describe equip‐
ment and functions which are not installed in
your vehicle, for example on account of the spe‐
cial equipment selected or the country specifica‐
tion. This also applies to safety-relevant func‐
tions and systems. Please comply with the
relevant laws and regulations when using the
corresponding functions and systems.
Drive-off assistant
Principle
The system provides support when driving off on
upward gradients.
Driving off
1. Hold the vehicle in place with the foot brake.
2. Release the foot brake and drive off without
delay.
Anti-lock Brake System
ABS
After the foot brake is released, the vehicle is
held in place for approximately 2 seconds.
ABS prevents the wheels from locking when the
brakes are applied.
Depending on the vehicle's load or when towing
a trailer, the vehicle may roll backwards a little.
Steering control is retained even during full brak‐
ing, which enhances active road safety.
Dynamic Stability Control
DSC
ABS is operational each time the engine is star‐
ted.
Principle
Brake assist
The system reduces engine power output and
applies the brakes on individual wheels thereby
helping, within the limits imposed by physics, to
keep the vehicle safely on course.
When the brake pedal is depressed quickly, the
system automatically applies maximum braking
power. This keeps the stopping distance as short
as possible in full braking situations. The advan‐
tages offered by the Anti-lock Brake System
ABS can also be utilised to the full.
General
DSC detects the following unstable driving con‐
ditions, for example:
The pressure on the brake should be maintained
for the duration of the full-braking process.
▷ Loss of traction at the rear which can lead to
oversteer.
▷ Loss of grip at the front wheels which can
lead to understeer.
Adaptive brake assist
In conjunction with Active Cruise Control ACC,
this system ensures that the brakes respond

To assist driving stability, re-activate DSC as
soon as possible.
Safety notes
WARNING
Deactivating DSC
The system does not relieve you of your per‐
sonal responsibility to assess the traffic situa‐
tion correctly. Due to system limitations, it can‐
not respond independently and appropriately in
all traffic conditions. There is a risk of accident.
Adapt your driving style to the traffic conditions.
Observe the traffic situation and intervene ac‐
tively if the situation warrants it.
Hold the button down until DSC OFF is
displayed in the instrument cluster and
the DSC OFF indicator lamp is illuminated.
Activating DSC
Press the button.
DSC OFF and the DSC OFF indicator
lamps are extinguished.
WARNING
Display
When driving with a roof load, for example with
a roof rack, the higher centre of gravity can
mean that driving safety is no longer guaran‐
teed in critical driving situations. There is a risk
of accident or material damage. Do not deacti‐
vate Dynamic Stability Control DSC when driv‐
ing with a roof load.
In the instrument cluster
DSC OFF is displayed in the instrument cluster
when DSC is deactivated.
Indicator and warning lamps
If the indicator lamp is illuminated: DSC is
deactivated.
Overview
If the indicator lamp is flashing: DSC is
regulating the acceleration and braking
forces.
Button in the vehicle
If the indicator lamp is illuminated: DSC has
failed.
Dynamic Traction Control
DTC
DSC OFF
Principle
DTC is a variant of Dynamic Stability Control
DSC and is optimised for forward momentum.
Deactivate/activate DSC
General
Driving stability during acceleration and cornering
is restricted if DSC is deactivated.
In special road conditions, for example on un‐
cleared, snow-covered roads or on loose surfa‐
ces, the system ensures maximum forward mo‐
mentum, but with restricted driving stability.

Driving Stability Control Systems
CONTROLS
General
Display
Activating DTC provides maximum traction. Driv‐
ing stability assistance during acceleration and
cornering is limited.
Display in the instrument cluster
When DTC is activated, TRACTION is displayed
in the instrument cluster.
Activating DTC briefly may be useful in the
following situations:
Indicator and warning lamps
▷ When driving in slush or on uncleared, snow-
covered roads.
The indicator lamp is illuminated: DTC
has been activated.
▷ When starting in deep snow or on a loose
surface.
▷ When driving with snow chains.
Automatic program change
The system switches automatically to "DSC ON"
in certain situations:
Overview
▷ If Active Cruise Control with Stop&Go func‐
tion ACC is activated.
Button in the vehicle
▷ When the Intelligent Safety Systems are
braking the vehicle.
▷ In the event of a flat tyre.
xDrive
Principle
xDrive is the all-wheel system of the vehicle. The
interaction between xDrive and Dynamic Stability
Control DSC further optimises traction and driv‐
ing dynamics. xDrive distributes the drive forces
variably between the front and rear axles accord‐
ing to the driving situation and road surface con‐
ditions.
DSC OFF
Activate/deactivate DTC
Activating DTC
Press the button.
The Driving Experience Control makes it possi‐
ble to change the four-wheel drive distribution
from traction-based to sport-based.
TRACTION is displayed in the instru‐
ment cluster and the DSC OFF indicator lamp is
illuminated.
Efficient4x4
Efficient4x4 reduces consumption by using the
four-wheel drive system according to require‐
ments.
Deactivating DTC
Press the button again.
TRACTION and the DSC OFF indicator
light are extinguished.

M sports steering
M sports steering creates a direct driving style by
using smaller steering angles. M sports steering
features variable steering force support that
takes speed and transverse acceleration into ac‐
count. The system enhances agility and im‐
proves handling while maintaining a sporty driv‐
ing style; for example, on tight corners or during
avoidance manoeuvres. At the same time, it en‐
sures improved comfort during parking, turning,
and manoeuvring.
