Driving stability control systemsVehicle equipmentAll standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Antilock Brake System ABS ABS prevents locking of the wheels during
braking.
The vehicle remains steerable 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 maximum braking
force boost. This then reduces braking dis‐ tance to a minimum during full braking. This
system utilizes all of the benefits provided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
When equipped with Driving Assistant Plus or
with Active Cruise Control with Stop & Go
function, ACC is supported by the braking in‐
tervention if there is a possible risk of collision.
To do this, the braking force is automatically increased if the braking pressure is insufficient
when the brakes are applied.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 away on gradi‐
ents. The parking brake is not required.1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive away
without 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
rolling back.◀
DSC Dynamic Stability
Control
The concept DSC prevents traction loss in the driving
wheels when driving away and accelerating.
DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Sub‐
ject to physical limits, DSC helps to keep the
vehicle on a steady course by reducing engine
speed and by applying brakes at individual
wheels.

The indicator lamp lights up: DTC Dy‐
namic Traction Control is activated.
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 as required for the road surface and
driving style.
Programs The system offers several different programs.
The programs can be selected via the Driving
Dynamics Control, refer to page 132.
SPORT/SPORT+
Consistently sporty control of the shock ab‐
sorbers for greater driving agility.
COMFORT/ECO PRO
Balanced tuning between the COMFORT+ and
SPORT/SPORT+ programs.
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. A mal‐
function has occurred in the self-leveling sus‐
pension. 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.

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.
Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent hydroplaning.◀
Driving through water 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 6 mph/10 km/h.
Adhere to water depth and speed limita‐
tions
Do not exceed this water depth and walking
speed; otherwise, the vehicle's engine, the
electrical systems and the transmission may
be damaged.◀
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 when this is neces‐
sary.
The vehicle maintains steering responsive‐
ness. You can still avoid any obstacles with a
minimum of steering effort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.Objects in the area around the pedals
No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the area of motion of the pedals;
otherwise, the function of the pedals could be
impeded while driving
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 fixed in
place.
Ensure that the floor mats are securely fas‐
tened again after they were removed for clean‐
ing, for example.◀
Driving in wet conditions When roads are wet coated with road salt or
there is heavy rain, briefly exert gentle pres‐
sure on the brake pedal every few miles.
Ensure that this action does not endanger
other road users.
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.
Hills
Drive long or steep downhill gradients in the
gear in which the least braking is required.
Otherwise, the brake system may overheat, re‐
sulting in a reduction in the brake system effi‐ ciency.
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if necessary.
Avoid load on the brakes
Avoid placing excessive load on the
brake system. Light but consistent brake pres‐
sure can lead to high temperatures, brake wear
and possibly even brake failure.◀Seite 183Things to remember when drivingDriving tips183

Wheel and tire combination
Information on the correct wheel-tire combina‐
tion and rim versions for your vehicle can be
obtained from your service center.
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
The manufacturer of your vehicle recom‐
mends that you use only wheels and tires that
have been approved for your particular vehicle
model.
For example, despite having the same official
size ratings, variations can lead to body con‐
tact 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 ensure the operating safety of the vehi‐
cle if they are mounted.◀
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
Due to technical factors associated with their
manufacture, tires do not achieve their full
traction potential until after an initial breaking-
in period.
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
The manufacturer of your vehicle recommends
winter tires for winter roads or at temperatures
below +45 ℉/+7 ℃.
Although so-called all-season M+S tires do
provide better winter traction than summer
tires, they do not provide the same level of per‐
formance as winter tires.
Maximum speed of winter tires If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then display a corresponding sign in the field
of vision. You can obtain this sign from the tire
specialist or from your service center.
Maximum speed for winter tires
Do not exceed the maximum speed for
the winter tires; otherwise, tire damage and ac‐
cidents can occur.◀
Run-flat tires If you are already using run-flat tires, for your
own safety you should replace them only with
the same kind. No spare tire is available in theSeite 204MobilityWheels and tires204
