Information on braking
126
Handbrake
127
Parking
128WARNING■ Greater physical effort for braking is required when the engine is switch-
ed off – risk of accident!■
During the braking procedure on a vehicle with manual transmission,
when the vehicle is in gear and at low revs, press the clutch pedal. Other-
wise, the functionality of the brake system may be impaired – risk of acci-
dent!
■
When leaving the vehicle never leave persons leave unattended in the
vehicle who could release the brake. The vehicle might then move off – risk of accident!
■
Observe the recommendations on the new brake pads » page 132.
CAUTION
Never let the brakes slip with light pressure on the pedal if braking is not nec-
essary. This causes the brakes to overheat and can also result in a longer brak-
ing distance and excessive wear.
Information on braking
Read and observe
and on page 126 first.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driv-
ing style.
The brake pads wear more quickly if a lot of journeys are completed in towns
and over short distances or if a very sporty style of driving is adopted.
If operated under severe conditions , the thickness of the brake pads must be
checked by a specialist garage between service appointments as well.
126Driving

Wet roads or road salt
The performance of the brakes can be delayed as the brake discs and brake
pads may be moist or have a coating of ice or layer of salt on them in winter.
The brakes are cleaned and dried by applying the brakes several times »
.
Corrosion
Corrosion on the brake discs and dirt on the bake pads occur if the vehicle has
been parked for a long period and if you do not make much use of the braking
system. The brakes are cleaned by applying the brakes several times »
.
Long or steep slopes
Before travelling a long distance with a steep gradient, reduce speed and shift
into the next lowest gear. As a result, the braking effect of the engine will be
used, reducing the load on the brakes. Any additional braking should be com-
pleted intermittently, not continuously.
Emergency brake display
If the brakes are applied in full and the vehicle systems evaluate the situation
as dangerous for the traffic following behind, the brake light flashes automati-
cally.
After the speed was reduced below around 10 km/h or the vehicle was stop-
ped, the brake light stops flashing and the hazard warning light system
switches on. The hazard warning light system is switched off automatically af-
ter accelerating or driving off again.
Faults in the brake surface
If it is found that the braking distance has suddenly become longer and that
the brake pedal can be depressed further, the brake system may be faulty.
Visit a specialist garage immediately and adjust your style of driving appropri-
ately, as you will not know the exact extent of the damage.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system.
The level of the brake fluid is monitored electronically » page 32,
Brake sys-
tem .
Brake booster
The brake booster increases the pressure generated with the brake pedal. The
brake booster only operates when the engine is running.
WARNINGOnly apply the brakes for the purpose of drying and cleaning the brake
discs if the traffic conditions permit this. Do not place any other road users
in jeopardy.

D/S - mode for driving forward (Normal program) / mode for driving
forward (Sport program)
The system switches from one mode to the other by moving the selector lever
into the spring-loaded position
» Fig. 149 .
In mode D or S, the forward gears are shifted automatically depending on the
engine load, the operation of the accelerator pedal, the vehicle speed, and the
selected driving mode .
In mode S , the forward gears are shifted automatically up and down at high-
er engine speeds than in mode D.
If the Sport driving mode is selected with the engine running » page 157, Se-
lection of the driving mode (Driving Mode Selection) , the transmission is auto-
matically set in the S mode.
E – Economical driving mode
If the driving mode Eco or Individual (engine - Eco) » page 157 is selected and
the selection lever is in the setting D/S, the transmission is automatically set
to mode E. This mode cannot be selected with the selector lever.
In mode E , the forward gears are shifted automatically up and down at lower
engine speeds than in mode D.
Selector lever lock
Fig. 150
Shift lock button
Read and observe and on page 129 first.
The selector lever is locked in mode P and N to prevent that the forward driv-
ing is selected accidentally, thereby setting the vehicle in motion.
The selector lever is locked only when the vehicle is stationary and at speeds
up to 5 km/h.
The selector lever lock is indicated by the illumination of the warning light .
The selector lever is not locked when quickly moving across the position
N
(e.g. from R to D/S ). This, for example, helps to rock out a vehicle that is stuck,
e.g. in a bank of snow. The selector lever lock will engage if the lever is in posi-
tion N for more than approx. 2 seconds without the brake pedal being de-
pressed.

Assist systems
General information
Introduction
This chapter contains information on the following subjects:
Radar sensor
135WARNINGThe following general information regarding the use of assistance systems
must be observed.■
The assistance systems only serve to support and do not relieve the driv-
er of the responsibility for driving the vehicle.
■
The increased safety provision, as well as the increased occupant protec-
tion provided by the assistance systems must not tempt you to take risks -
risk of accident!
■
Adjust the speed and driving style to the current visibility, weather, road
and traffic conditions.
■
The assistance systems have physical and system-related limitations. For
this reason, the driver may experience some undesired or delayed system
responses in certain situations. You should therefore always be alert and
ready to intervene!
■
Only activate, deactivate or set the assistance systems so that you have
the vehicle fully under control in every traffic situation - risk of accident!
Radar sensor
Fig. 154
Mounting location of the radar
sensor
Read and observe on page 135 first.
The radar sensor » Fig. 154 (From here on referred to as sensor) is used to as-
sess the traffic situation in front of the vehicle.
The sensor can distinguish objects by radiating and receiving electromagnetic waves.
The sensor is a component of the ACC » page 150 and Front Assist
» page 155 systems.
The sensor function may be impaired in the events of one of the following. ▶ The sensor is soiled by mud, snow and the like.
▶ The area in front and around the sensor is obscured by labels, auxiliary lights
and similar.
▶ When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
If the sensor is covered or dirty, the corresponding message appears in the in-
strument cluster display for the ACC system » page 155 or Front Assist system
» page 157 .
WARNING■
If you suspect that the sensor is damaged, deactivate the ACC system
» page 150 and Front Assist system » page 155. Have the sensor checked
by a specialist garage.■
The sensor can become misaligned by collisions or by damage to the front
of the vehicle, the wheel arch or the underside of the vehicle. This can lead
to impaired function of the sensor - risk of accidents! Have the sensor
checked by a specialist garage.
■
The area in front and around the sensor should not be obscured by labels,
auxiliary lights and similar. This can lead to impaired function of the sensor
- risk of accidents!
CAUTION
Remove the snow with a brush and the ice with a solvent-free de-icer.

This chapter describes the functions of the brake and stabilization systems.
The error display is in Chapter » page 31, Warning lights .
The brake and stabilization systems are automatically activated each time the
ignition is switched on, unless otherwise indicated.
WARNINGThe general information relating to the use of assistance systems must be
observed » page 135, in section Introduction .
Stability Control (ESC)
Read and observe
on page 136 first.
The ESC improves vehicle stability in dynamic driving situations, such as when
the vehicle starts to skid.
The ESC monitors whether the desired direction of the current vehicle motion
is occurring. In case of any deviation (e.g. oversteer), the ESC automatically
brakes individual wheels to maintain the desired direction.
During an intervention of the system, the warning light flashes in the instru-
ment cluster.
Enable/disable ESC Sport
The activation of the ESC sports allows a sportier driving style. With a slight
over or under steering of the vehicle take no ESC interventions take place and
the TCS is restricted so that the spinning of the wheels of the driven axle can
occur.
The activation or deactivation of the ESC sports can be done in one of two
ways. ▶ By pressing the Symbol key for the activation and briefly pressing the but-
ton for the deactivation » Fig. 155 on page 136 .
▶ Infotainment » Owner´s Manual Infotainment , chapter CAR - vehicle set-
tings .
Upon activation, in the instrument cluster the indicator light comes on and
the display shows the following message.ESC sport: directional stabil. restricted.ESC SPORT
Upon deactivation, in the instrument cluster the control indicator
turns off
and the display shows the following message.
Stabilisation control (ESC) activated.ESC ON
Anti-lock braking system (ABS)
Read and observe
on page 136 first.
ABS prevents the wheels locking when braking. Thus helping the driver to
maintain control of the vehicle.
The intervention of the ABS is noticeable from the pulsating movements of
the brake pedal which is accompanied by noises.
When the ABS system is active, do not brake periodically or reduce the pres- sure on the brake pedal.
Traction control (TCS)
Fig. 155
System button: Vehicle with ESC / vehicle without ESC
Read and observe
on page 136 first.
TCS prevents the spinning of the wheels of the driven axle. TCS reduces the
drive power transmitted to the wheels in the case of slipping wheels. Thus, for
example, driving on road surfaces with low grip is made easier.
