Preventing the engine stop using thebrake pedal
The engine stop can be actively prevented
within one second after the vehicle comes to a
standstill.▷Depress the brake pedal briefly and force‐
fully immediately after the vehicle comes to
a standstill.▷Then continue depressing the brake pedal
with normal braking force.
Activating/deactivating the system
manually
Press the button.
▷LED lights up: the Auto Start/Stop function
is deactivated.
The engine is started during an automatic
engine stop.
The engine can only be stopped or started
via the Start/Stop button.▷LED goes out: the Auto Start/Stop function
is activated.
Automatic deactivation
In certain situations, the Auto Start/Stop func‐
tion is deactivated automatically in the interest
of safety, for example if the driver's absence is
detected.
Malfunction The indicator lamp lights up. The au‐
tomatic engine start/stop function no
longer switches of the engine auto‐
matically.A message appears on the Control
Display. It is possible to continue driving. Have
the system checked.
Parking brake
The concept The parking brake is primarily intended to pre‐
vent the vehicle from rolling while parked; it
brakes the rear wheels.
Indicator lamp The indicator lamp lights up and an
acoustic signal sounds when driving
away. The parking brake is still set.
Setting The lever engages automatically.
Releasing
Pull up slightly, press the button, and lower the
lever.
Notes Using the parking brake while driving
If it should become necessary to use the
parking brake while driving, do not pull the
parking brake too forcefully. Keep the button
on the parking brake lever pressed at all times.
Excessive application of the parking brake can
block the rear wheels and lead to fishtailing of
the vehicle.◀

Driving stability control systemsVehicle equipmentThis 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
systems.
When using the features and systems descri‐
bed here, adhere to local regulations.
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.
Electronic brake-force
distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Brake assistant When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost. It thus helps to achieve the short‐
est possible braking distance during full brak‐
ing. This system utilizes all of the benefits pro‐
vided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.Dynamic Stability Control
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. Sub‐
ject 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.
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.◀
Deactivating DSC: DSC OFF When DSC is deactivated, driving stability is
reduced during acceleration and when driving
in bends.
To increase vehicle stability, activate DSC
again as soon as possible.

The system stores and maintains the speed.
Accelerating using the lever Accelerating slightly:
Press the lever to the resistance point, arrow 1,
until the desired speed is reached.
Accelerating significantly:
Press the lever beyond the resistance point,
arrow 1, until the desired speed is reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores and
maintains the speed.
Decreasing speed
Repeatedly pull the lever to the resistance
point or beyond, arrow 2, until the desired
speed is displayed.▷Each time the lever is pulled to the resist‐
ance point, the desired speed is decreased
by approx. 1 mph/1 km/h.▷Each time the lever is pulled beyond the
resistance point, the desired speed is re‐
duced by up to 5 mph/10 km/h until the
minimum speed of 20 mph/30 km/h is ach‐
ieved.
The system stores and maintains the speed.
Deactivating cruise control
Push the lever upwards or downwards, ar‐
row 3.
The displays in the speedometer go out.
In addition, the system is automatically deacti‐
vated when:
▷The brakes are applied.▷Selector lever position N is engaged or
transmission position D is disengaged.▷When DTC is activated or DSC is deacti‐
vated.▷When DSC or ABS is intervening.
Cruise control is not deactivated by depressing
the accelerator pedal. Once the accelerator
pedal is released, the stored speed is achieved
again and maintained.
Warning light The warning lamp comes on when
cruise control has been deactivated
as a result of DSC intervention, for
example. A message appears on the Control
Display.
Resuming a speed stored beforehand Press the button, arrow 4. The last stored
speed is resumed and maintained.
In the following cases, the stored speed value
is deleted and cannot be called up again:▷When driving stability control systems in‐
tervene.▷When selector lever position N is engaged
or transmission position D is disengaged.▷When the ignition is switched off.

Hot exhaust systemHot exhaust system
High temperatures are generated in the
exhaust system.
Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that flammable materials, e. g. hay, leaves,
grass, etc. do not come in contact with the hot
exhaust system during driving, while in idle po‐
sition mode, or when parked. Such contact
could lead to a fire, and with it the risk of seri‐
ous personal injury as well as property dam‐
age.
Do not touch hot exhaust pipes; otherwise,
there is the danger of getting burned.◀
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 without a direct con‐
nection to an external aerial in the vehicle's
passenger compartment. Otherwise, the vehi‐
cle electronics and mobile communication de‐
vices can interfere with each other. In addition,
there is no assurance that the radiation gener‐
ated during transmission will be discharged
from the vehicle interior.◀
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.◀The risk of hydroplaning increases as the tire
tread depth decreases. Minimum tread depth,
refer to page 239.
Driving through water Drive though calm water only if it is not deeper
than 12 inches/30 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.
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 drivingSeite 133Things to remember when drivingDriving tips133

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.◀
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 95. 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
can be identified by a star 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
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.
