Brakes and parking
Introduction
This chapter contains information on the following subjects:
Information for braking
107
Handbrake
108
Parking
109WARNING■ Greater physical effort is required for braking when the engine is switch-
ed off – risk of accident.■
The clutch pedal must be depressed when braking on a vehicle with man-
ual transmission, when the vehicle is in gear and at low revs. Otherwise,
the functionality of the brake system may be impaired – risk of accident!
■
When leaving the vehicle, never leave persons who might, for example,
release the handbrake or take the vehicle out of gear unattended, in the
vehicle. The vehicle might then move off – risk of accident.
■
Observe the recommendations on the new brake pads » page 113.
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 for braking
Read and observe
and on page 107 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.
107Starting-off and driving

Under these severe conditions , the thickness of the brake pads must also be
checked by a specialist garage between services.
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 brake 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 and dried 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 control unit for the braking system con-
siders the situation to be dangerous for the following traffic, the brake light
flashes automatically.
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.
Fault in the brake system
If it is found that the braking distance has suddenly become longer and that
the brake pedal can be depressed further, there may be a fault in the brake
system.
Visit a specialist garage immediately and adjust your style of driving appropri-
ately as you will not know how great the damage is.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system.
The fluid level is monitored electronically » page 34,
Brake system
.
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.
Handbrake

Modes and use of selector leverFig. 110
Selection lever / lock button / display
Read and observe
and on page 110 first.
When the ignition is switched on, the gearbox mode and the currently selected gear are indicated in the display » Fig. 110.
The following modes can be selected with the selector lever » Fig. 110.
P
– Parking mode
The driven wheels are locked mechanically in this mode.
Parking mode must only be selected when the vehicle is stationary.
R
- Reverse gear
Reverse gear can only be engaged when the vehicle is stationary and the en-
gine is at idling speed.
N
- Neutral
Power transmission to the drive wheels is interrupted in this mode.
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. 110 .
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 higher
engine speeds than in mode D.
Selector lever lock
Read and observe
and on page 110 first.
The selector lever is locked in the P and N modes to prevent the forwards trav-
el mode from being selected accidentally and 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.
Releasing selector lever from mode P or N (selector lever lock)
›
Press the brake pedal and the lock button at the same time in the direction
of
1
» Fig. 110 on page 111 .
Just depress the brake pedal, if you would like to change from the mode N to
D/S .
Defective selector lever lock
If the selector lever lock is defective or its power supply is interrupted (e.g. dis-
charged vehicle battery, faulty fuse), the selector lever can no longer be moved
out of position P in the normal manner and the vehicle can no longer be driven.
The selector lever must be emergency released » page 181.
Note
If you want to move the selector lever from mode P to mode D/S or vice versa,
move the selector lever quickly. This prevents modes R or N from being selec-
ted accidentally.111Starting-off and driving

Assist systems
Braking and stabilisation systems
Introduction
This chapter contains information on the following subjects:
Electronic Stability Control (ESC)
115
Anti-lock Braking System (ABS)
115
Traction Control System (TCS)
115
Electronic Differential Lock (EDL and XDS)
116
Hydraulic Brake Assist (HBA)

Multi-collision brake (MCB)
116
This chapter deals with the functions of the braking and stabilisation systems,
with the error indicator referred to in chapter » page 33, Warning lights .
The braking and stabilisation systems are automatically activated each time the ignition is switched on.
WARNING■ A lack of fuel can cause irregular engine running or cause the engine to
shut down. The brake assist systems would then fail to function – risk of
accident!■
The increased safety provided by the brake assist systems must not
tempt you to take safety risks – risk of accident!
■
Adjust the speed and driving style to the current visibility, weather, road
and traffic conditions.
Electronic Stability Control (ESC)
Read and observe
on page 115 first.
The ESC improves vehicle stability in dynamic driving situations, such as whenthe 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.
Anti-lock Braking System (ABS)
Read and observe
on page 115 first.
ABS prevents the wheels locking when braking. Thereby, it helps 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 pump the brakes or lift off the brake
pedal.
Traction Control System (TCS)
Fig. 113
System button: Activating/deac-
tivating TCS
Read and observe on page 115 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. Thereby,
for example, driving on road surfaces with low grip is made easier.
During a TCS intervention, the indicator light flashes in the instrument clus-
ter.
Activating/deactivating TCS
The activation or deactivation of TCS can be done, depending on equipment, in
one of the following ways.
› In Infotainment
» Operating instructions for Infotainment , chapter Vehicle
settings (CAR button) .
› By briefly pressing the symbol key
» Fig. 113 .
115Assist systems

Upon deactivation, in the instrument cluster the indicator light illuminates
and the display shows the following message.
Traction control (TCS) deactivated.
ASR OFF
Upon activation, in the instrument cluster the indicator turns
and the display
shows the following message.
Traction control (TCS) activated.
ASR ON
The TCS should normally always be enabled. The system should be deactivated
only in the following situations, for example.
› When driving with snow chains.
› When driving in deep snow or on a very loose surface.
› When “rocking a car free” when it has become stuck.
Electronic Differential Lock (EDL and XDS)
Read and observe
on page 115 first.
EDL
EDL prevents the turning of the respective wheel of the driven axle. EDL
brakes the spinning wheel, if necessary, and transmits the driving force to the
other driving wheel. Driving becomes easier on road surfaces with different
traction under each wheel of the driven axle.
EDL switches off automatically to avoid excessive heat generation on the
brake of the wheel being braked. The vehicle can continue to be driven and
has the same characteristics as a vehicle not fitted with EDL. Once the brakes
have cooled down, there is an automatic re-activation of EDL.
XDS
XDL is an extension to the electronic differential lock. XDL does not respond to
traction, but to the load relief of the inner front wheel of the driving axle dur-
ing fast cornering.
The automatic brake intervention on the brake of the wheel with reduced load
prevents the wheel from spinning. Thus, the traction is improved and the vehi-
cle can continue to follow the desired track.
Hydraulic Brake Assist (HBA)
Read and observe
on page 115 first.
HBA increases the braking effect and helps to shorten the braking distance.The HBA is activated by very rapid depression of the brake pedal. To achieve
the shortest possible braking distance, the brake pedal must be applied firmly
until the vehicle has come to a complete standstill.
HBA is automatically switched off when the brake pedal is released.
Hill Hold Control (HHC)
Read and observe
on page 115 first.
HHC allows you to move your foot from the brake pedal to the accelerator ped-al without having to use the handbrake when pulling away on a gradient.
The system holds the brake pressure produced by the activation of the brake
pedal for approx. 2 seconds after the brake pedal is released.
The brake pressure drops gradually the more you operate the accelerator ped-
al. If the vehicle does not start off within 2 seconds, it starts to roll back.
HHC is active on slopes of >5 % when the driver door is closed. HHC is always only active on slopes pulling away forwards or in reverse.
Multi-collision brake (MCB)
Read and observe
on page 115 first.
The MCB helps to decrease speed after a collision through automatic brakinginterventions and to stabilize the vehicle. This reduces the risk of a subse-
quent crash due to uncontrolled vehicle movement.
The automatic brake interventions can take place only if the following condi-
tions are met.
A head-on or side collision occurred.
The impact speed was higher than approx. 10 km/h.
The brakes, the ESL and other required electrical systems remain function-
al after impact.
The accelerator pedal is not actuated.
