Brakes and parking
Introduction
This chapter contains information on the following subjects:
Information on braking
130
Handbrake
131
Parking
132WARNING■ 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 who might, for example,
release the handbrake or take the vehicle out of gear unattended in the ve-
hicle. The vehicle might then move off – risk of accident!
■
Observe the recommendations on the new brake pads » page 136, New
brake pads .
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 130 first.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driv-
ing style.
130Driving
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.
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 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.
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 35,
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.
Handbrake

lights up when the handbrake is applied, pro-
vided the ignition is on.
A warning signal sounds if the vehicle is inadvertently driven off with the
handbrake applied.
The following message is shown in the information cluster display. Release the handbrake!
RELEASE HANDBRAKE
131Starting-off and Driving
The handbrake warning is activated if the vehicle is driven at a speed of more
than around 5 km/h for more than 3 seconds.WARNINGPlease note that the handbrake must be fully released. A handbrake which
is only partially released can result in the rear brakes overheating. This can
have a negative effect on the operation of the brake system – risk of acci-
dent!

›
Move the shift lever fully to the left and then forward into R posi-
tion » Fig. 133 .
The reversing lights will come on once reverse gear is engaged, provided the ignition is on.
WARNINGNever engage reverse gear when driving – risk of accident!
CAUTION
■ If not in the process of changing gear, do not leave your hand on the gear-
shift lever while driving. The pressure from the hand can cause the gearshift
mechanism to wear excessively.■
When stopping on a slope, never try to hold the vehicle using the accelerator
pedal – this may lead to gear damage.
Pedals
The operation of the pedals must not be hindered under any circumstances!
132Driving

The 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. 134 .
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 160, Se-
lection of travel mode (Driving Mode Selection) , the transmission is automati-
cally set in the S mode.
E – Economical driving mode
If the driving mode Eco or Individual (engine - Eco) » page 160 is selected and
the selection lever is in the setting D/S, transmission is automatically set in
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
Read and observe
and on page 133 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.
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. 134 on page 133 .
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 unlocked specially » page 226.
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 that you accidentally select
mode R or N.

This chapter deals with the functions of the braking and stabilisation systems,
with the error indicator referred to in chapter » page 34, 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!
■
Always adjust your speed and driving style to the current visibility, weath-
er, road and traffic conditions.
Electronic Stability Control (ESC)
Read and observe
on page 138 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
ESC Sport allows for sportier driving style. The activation of the ESC sport
leads to the ASR being deactivated and no ESC interventions will occur in the
event of slight over- or under-steering occurring.
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. 137 on page 139 .
› In Infotainment
» Operating instructions for Infotainment , chapter Vehicle
settings (CAR button) .
Upon activation, in the instrument cluster the indicator light comes on and
the display shows the following message.
ESC sport: Limited driving stability.
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
Antilock Braking System (ABS)
Read and observe
on page 138 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.
138Driving
Traction Control System (TCS)Fig. 137
System button: Vehicle with ESC / vehicle without ESC
Read and observe
on page 138 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.
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. 137 .
› By briefly pressing the symbol key
» Fig. 137 .
Upon deactivation, in the instrument cluster the indicator light lights up and
the display shows the following message.
Traction control (ASR) deactivated.
ASR OFF
Upon activation, in the instrument cluster the indicator turns and the display
shows the following message.
Traction control (ASR) 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 it is necessary to “rock” a car free when it has become stuck.
Note
On vehicles without the ESC system, the warning light
does not illuminate
upon deactivation of the ASR system, but a message is only displayed on the
display of the instrument cluster.
Electronic Differential Lock (EDL and XDS)
Read and observe
on page 138 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.
Driver Steering Recommendation (DSR)
Read and observe
on page 138 first.
The DSR indicates to the driver in critical situations a steering recommenda-
tion in order to stabilise the vehicle. The DSR is activated, for example, on the
right and left vehicle side when braking sharply on different road surfaces.
139Assist systems
