Performance Control Performance Control enhances the agility of
the vehicle.
To increase maneuverability, with a corre‐
spondingly sporty driving style, wheels are
braked individually. The resulting braking
power is simultaneously largely compensated
by an engine intervention.
xDrive xDrive is the all-wheel-drive system of your ve‐
hicle. Concerted action by the xDrive and DSC
further optimize traction and driving dynamics.
The xDrive all-wheel-drive system variably dis‐
tributes the drive forces to the front and rear
axles as demanded by the driving situation and
road surface.

The following information is displayed:
▷With a navigation system: compass display
for the driving direction▷Pitch attitude with degree and percentage.▷Transverse gradient with degree indica‐
tion.▷Graphic display for the steering.HDC Hill Descent Control
The concept HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep
downhill gradients. Without applying the
brakes, the vehicle moves at slightly more than
walking speed. It the brakes are actively ap‐
plied, the system distributes force according to
the traction.
Vehicle stability and maneuverability are im‐
proved on downhill gradients.
Hill Descent Control can be activated at
speeds below approx. 22 mph/35 km/h. When
driving downhill, the vehicle reduces its speed
and then keeps its speed constant.
Only use HDC in low gears or in selector lever
position D or R.
Increasing or decreasing vehicle
speed
Specify desired speed in the range from ap‐
prox. 4 mph/6 km/h to approx. 15 mph/25 km/h
using the rocker switch of the cruise control on
the steering wheel. Vehicle speed can be
changed by lightly accelerating.▷Press the rocker switch up to the point of
resistance: the speed increases gradually.▷Press up the rocker switch past the point
of resistance: the speed increases while
the rocker switch is pressed.▷Press the rocker switch down to the point
of resistance: the speed decreases gradu‐
ally.Seite 131Driving stability control systemsControls131

Malfunction
A message is displayed in the instrument clus‐
ter. HDC is not available, for example, due to elevated brake temperatures.
Dynamic Damping Control
The concept This system reduces undesirable vehicle mo‐
tion when using a dynamic driving style or trav‐
eling on uneven road surfaces.
The system enhances driving dynamics and
comfort fitting road surface and driving style.
Programs The system offers several different programs.
The programs can be selected via Driving Dy‐
namics Control.
SPORT
Consistently sporty control of the shock ab‐
sorbers for greater driving agility.
SPORT+ Consistently sporty control of the shock ab‐
sorbers for greater driving agility when driving
with limited driving stabilization.
COMFORT/ECO PRO Balanced control of the vehicle.
Variable sport steering The variable sport steering increases the
steering angle of the front wheels at large steering wheel angles, for example, in tight
curves or when parking. Steering becomes more direct.
It also varies the force required to turn the
wheels in accordance with the vehicle speed.
This results in a sporty steering response. In
addition, it becomes easier to steer during
parking and maneuvering.Seite 132ControlsDriving stability control systems132

Weather
In the event of unfavorable weather and light conditions, e. g. if there is rain, snowfall, slush,
fog or glare, this may result in poorer recogni‐
tion of vehicles as well as short-term interrup‐
tions for vehicles that are already detected. Drive attentively, and react to the current trafficsituation. If necessary, intervene actively, for
example by braking, steering or evading.
Engine power The desired speed is also maintained downhill,but may not be maintained on uphill grades if
engine power is insufficient.

justed using the buttons on the steering wheel.
The system maintains the desired speed. The
system accelerates and brakes automatically
as needed.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
Information
WARNING
The system does not release from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sys‐
tem, it cannot independently react to all traffic
situations. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively intervene in the re‐
spective situations.◀
WARNING
The use of the system can lead to an in‐
creased risk of accidents in the following situa‐
tions:▷On winding roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
There is risk of accidents or risk of property
damage. Only use the system if driving at con‐
stant speed is possible.◀
WARNING
The desired speed can be incorrectly ad‐
justed or called up by mistake. There is risk of
an accident. Adjust the desired speed to the
traffic conditions. Watch traffic closely and ac‐
tively intervene in the respective situations.◀

HillsWARNING
Light but consistent brake pressure can
lead to high temperatures, brakes wearing out
and possibly even brake failure. There is risk of
an accident. Avoid placing excessive stress on
the brake system.◀
WARNING
In idle state or with the engine switched
off, safety-relevant functions are restricted or
not available anymore, e.g., braking effect of
the engine or braking force and steering sup‐
port. There is risk of an accident. Do not drive
in idle state or with the engine switched off.◀
Drive long or steep downhill gradients in the
gear that requires least braking efforts. Other‐
wise the brakes may overheat and reduce
brake efficiency.
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if needed.
Brake disc corrosion
Corrosion on the brake discs and contamina‐
tion on the brake pads are furthered by the fol‐
lowing circumstances:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion will built up when the maximum
pressure applied to the brake pads during
braking is not reached - thus discs don't get
cleaned.
Corrosion buildup on the brake discs will cause
a pulsating effect on the brakes in their re‐
sponse - generally that cannot be corrected.
Condensation under the parked
vehicle
When using the automatic climate control,
condensation water develops collecting under‐
neath the vehicle.
Driving on racetracksHigher mechanical and thermal loads during
racetrack operation lead to increased wear.
This wear is not covered by the warranty. The
vehicle is not designed for motorsports com‐
petitive use.Seite 185Things to remember when drivingDriving tips185

shop. After rotating, check the tire pressure
and correct if needed.
Rotating the tires between the axes is not per‐
missible on vehicles with different tire sizes or
rim sizes on the front and rear axles.
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels.
Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.
Run-flat tires
Label
RSC label on the tire sidewall.
The wheels consist of tires that are self-sup‐
porting, to a limited degree, and possibly spe‐
cial rims.
The support of the sidewall allows the tire to
remain drivable to a restricted degree in the
event of a tire inflation pressure loss.
Follow the instructions for continued driving
with a flat tire.
Changing run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire.
A dealer’s service center will be glad to answer
additional questions at any time.
Repairing a flat tire
Safety measures▷Park the vehicle as far away as possible
from passing traffic and on solid ground.▷Switch on the hazard warning system.▷Secure the vehicle against rolling away by
setting the parking brake.▷Turn the steering wheel until the front
wheels are in the straight-ahead position
and engage the steering wheel lock.▷Have all vehicle occupants get out of the
vehicle and ensure that they remain out‐
side the immediate area in a safe place,
such as behind a guardrail.▷If necessary, set up a warning triangle at an
appropriate distance.
Mobility System
The concept
With the Mobility System, minor tire damage
can be sealed temporarily to enable continued
travel. To accomplish this, sealant is pumped
into the tires, which seals the damage from the
inside.
The compressor can be used to check the tire
inflation pressure.
Information
▷Follow the instructions on using the Mobi‐
lity System found on the compressor and
sealant container.▷Use of the Mobility System may be ineffec‐
tive if the tire puncture measures approx.
1/8 in/4 mm or more.▷Contact a dealer’s service center or an‐
other qualified service center or repair
shop if the tire cannot be made drivable.▷If possible, do not remove foreign bodies
that have penetrated the tire.Seite 212MobilityWheels and tires212
