e.g., when there is the impending dan‐
ger of a collision or the distance to the
vehicle ahead is too small.

Driving stability control systemsVehicle features and optionsThis chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Antilock Brake System ABS ABS prevents locking of the wheels during
braking.
The vehicle contains its steering power even
during full brake applications, thus increasing
active safety.
ABS is operational every time you start the en‐
gine.
Brake assistant When you apply the brakes rapidly, this system
automatically produces the greatest possible
braking force boost. It reduces the braking dis‐
tance to a minimum during emergency stop.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.
Adaptive brake assistant In combination with the Active Cruise Control,
this system ensures that the brakes respond
even more rapidly when braking in critical sit‐
uations.Drive-off assistant
This system supports driving off on inclines.
The parking brake is not required.1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive off with‐
out delay.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load, the vehicle may
roll back slightly.
Driving off without delay
After releasing the foot brake, start driv‐
ing without delay, since the drive-off assistant
will not hold the vehicle in place for more than
approx. 2 seconds and the vehicle will begin to
roll back.◀
DSC Dynamic Stability
Control
The concept DSC prevents traction loss in the power
wheels when driving off and accelerating.
DSC also recognizes unstable vehicle condi‐
tions such as fishtailing or nose-diving. Within
the physical limits DSC helps to keep the vehi‐
cle on a steady course by reducing engine
speed and by applying brakes to the individual
wheels.
Note Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, not
even with DSC.

tor lamp go out.
Indicator/warning lights

Dynamic Damping Control The conceptThis 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.
Select the programs via the Driving Dynamics
Control, refer to page 142.
SPORT/SPORT+
Consistently sporty control of the shock ab‐
sorbers for greater driving agility.
COMFORT/ECO PRO Balanced tuning.COMFORT+
Comfort-oriented tuning of the shock absorb‐
ers for optimal traveling comfort.
Self-leveling suspension The concept The self-leveling suspension keeps the vehicle
height and ground clearance constant. The
height of the vehicle at the rear axle is main‐
tained at a predefined level under all load con‐
ditions.
The system ensures consistent comfort by keeping spring travel constant in all driving sit‐
uations.
Malfunction A Check Control message is displayed. The
system is disrupted. Vehicle handling may be
altered and driving comfort may be noticeably
reduced. Visit your nearest service center.
Driving Dynamics Control
The concept The Driving Dynamics Control can be used to
adjust the driving dynamics of the vehicle. For
this purpose various programs are available for
selection that are activated via the two buttons
of the Driving Dynamics Control and the DSC
OFF-button.Seite 142ControlsDriving stability control systems142

Mobile communication devices in the
vehicle
Mobile communication devices in the ve‐
hicle
It is not recommended to use mobile phones,
such as mobile phones, in the vehicle interior
without a direct connection to an external aer‐
ial. Otherwise, the vehicle's electronics and
mobile communication devices can interfere
with each other. In addition, there is no assur‐
ance that the radiation generated during trans‐
mission will be conducted away from the vehi‐
cle interior.◀
Hydroplaning Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent hydroplaning.◀
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as hydroplan‐
ing. It is characterized by a partial or complete
loss of contact between the tires and the road
surface, ultimately undermining your ability to
steer and brake the vehicle.
Driving through water Observe water level and speed
Do not exceed the maximum water level
and maximum speed; otherwise, the vehicle's
engine, the electrical systems and the trans‐
mission may be damaged.◀
Drive though calm water only and only if it is
not deeper than 9.8 inches/25 cm and at this
height, no faster than walking speed, up to
3 mph/5 km/h.
Braking safely
Your vehicle is equipped with ABS as a stand‐
ard feature.
Applying the brakes fully is the most effective
way of braking in situations needed.Steering is still responsive. You can still avoid
any obstacles with a minimum of steering ef‐
fort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.
In certain braking situations, the perforated
brake discs can cause functional problems.
However, this has no effect on the perform‐
ance and operational reliability of the brake.
Objects within the range of movement
of the pedals
No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the pedal area; otherwise, the
function of the pedals could be impeded while
driving and create the risk of an accident.
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved
for the vehicle and can be properly attached to
floor.
Ensure that the floor mats are securely fas‐
tened again after they were removed for clean‐
ing, e.g.◀
Driving in wet conditions When roads are wet, salted, or in heavy rain,
press brake pedal ever so gently every few
miles.
Ensure that this action does not endanger other traffic.
The heat generated in this process helps dry
the brake discs and pads.
In this way braking efficiency will be available
when you need it.Seite 191Things to remember when drivingDriving tips191

Changing wheels and tires
Mounting Information on mounting tires
Have mounting and balancing performed
only by a service center.
If work is not carried out properly, there is a
danger of subsequent damage and related
safety hazards.◀
Wheel and tire combination
You can ask the service center about the right
wheel/tire combination and wheel rim versions
for the vehicle.
Incorrect wheel and tire combinations impair
the function of a variety of systems such as
ABS or DSC.
To maintain good handling and vehicle re‐
sponse, use only tires with a single tread con‐ figuration from a single manufacturer.
Following tire damage, have the original wheel
and tire combination remounted on the vehicle
as soon as possible.
Approved wheels and tires
You should only use wheels and tires
that have been approved by the vehicle manu‐ facturer for your vehicle type; otherwise, e.g.,
despite having the same official size ratings,
variations can lead to chassis contact and with
it, the risk of severe accidents
The manufacturer of your vehicle cannot eval‐
uate non-approved wheels and tires to deter‐
mine if they are suited for use, and therefore
cannot guarantee the operating safety of the
vehicle.◀Recommended tire brands
For each tire size, the manufacturer of your ve‐
hicle recommends certain tire brands. These
can be identified by a star on the tire sidewall.
With proper use, these tires meet the highest
standards for safety and handling.
New tires Tire traction is not optimal due to manufactur‐
ing circumstances when tires are brand-new;
they achieve their full traction potential after a
break-in time.
Drive conservatively for the first
200 miles/300 km.
Retreaded tires
The manufacturer of your vehicle does not rec‐
ommend the use of retreaded tires.
Retreaded tires
Possibly substantial variations in the de‐
sign and age of the tire casing structures can
limit service life and have a negative impact on
road safety.◀
Winter tires
Winter tires are recommended for operating on
winter roads.
Although so-called all-season M+S tires pro‐
vide better winter traction than summer tires,
they do not provide the same level of perform‐
ance as winter tires.
