Driving stability control systemsVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series. Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and sys‐
tems.
When using the features and systems described
here, adhere to local regulations.
Antilock Brake System
ABS
ABS prevents locking of the wheels during braking.
Steerability is maintained even during full brak‐
ing. This increases active driving safety.
ABS is operational every time you start the en‐
gine.
Electronic brake-force distribution EBVThe system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
CBC Cornering Brake Control
When braking in curves or during a lane
change, driving stability and steering response
are improved further.
Brake assistant When the brakes are applied rapidly, this sys‐
tem automatically produces the maximum
braking force boost. In this way, the system
helps keep the braking distance as short aspossible. This system utilizes all of the benefits
provided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of full braking.
Dynamic Stability Con‐ trol DSC
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. Subject
to physical limits, DSC helps to keep the vehicle
on a steady course by reducing engine speed
and by applying brakes to the individual
wheels.
DSC is operational every time you start the en‐
gine.
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The laws of physics cannot be repealed, even
with DSC.
Do not reduce the additional safety margin
with a risky driving style, as otherwise there is a
risk of an accident. ◀

Braking safelyThe vehicle is equipped with ABS as a standardfeature.
Applying the brakes fully is the most effective
way of braking in situations when this is neces‐
sary.
The vehicle maintains steering responsiveness.
You can still avoid any obstacles with a mini‐
mum of steering effort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.
Do not let your foot rest on the brake
pedal
Do not drive with your foot resting on the brake
pedal. Even light but consistent pedal pressure
can lead to high temperatures, brake wear and
possibly even brake failure. ◀
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 fastened
again when they are returned after being re‐
moved, such as for cleaning. ◀
Driving in wet conditions When roads are wet or there is heavy rain,
briefly exert gentle pressure 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.
HillsDrive long or steep downhill gradients in the
gear in which the least braking is required. Oth‐
erwise, the brake system may overheat, result‐
ing 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.
Downshifting in manual mode of the Steptronic
transmission, refer to page 64.
Avoid load on the brakes
Avoid placing excessive load on the brake
system. Light but consistent brake pressure can
lead to high temperatures, brake wear and
possibly even brake failure. ◀
Do not drive in neutral
Never drive with the transmission in neu‐
tral, with the engine switched off or with the
clutch depressed; otherwise, you will have nei‐
ther the braking action of the engine or nor its
power assistance when braking or steering. ◀
Brake disc corrosion
Corrosion on the brake discs and contamina‐
tion on the brake pads are furthered by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected.

DOT … 0315: the tire was manufactured in the
3rd week of 2015.
Changing wheels and
tires
Mounting Information on mounting tires
Have mounting and balancing performed
only by a service center or tire specialist.
If this work is not carried out properly, there is
the danger of subsequent damage and related
safety hazards. ◀
Wheel and tire combination
Information on the right wheel and tire combi‐
nation and rim version for your vehicle can be
obtained from the 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 contact
and with it, the risk of severe accidents.
The manufacturer of your vehicle cannot evalu‐
ate 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. ◀Wheels with electronics for TPM Tire
Pressure Monitor
When mounting new tires or changing from
summer to winter tires or vice versa, only use
wheels with TPM electronics; otherwise, the
Tire Pressure Monitor will not be able to detect
a flat tire, refer to page 86. Your service center
will be glad to advise you.
Recommended tire brands
For each tire size, the manufacturer of your ve‐
hicle recommends certain tire brands. These
are indicated by the clearly visible marking on
the tire sidewall.
With proper use, these tires meet the highest
standards for safety and handling.
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 pro‐
vide better winter traction than summer tires,
they do not provide the same level of perform‐
ance as winter tires.
