Brakes and brake servo sys-
tems Introduction WARNING
● The brak e ser

vo only works when the en-
gine is running. Braking when the engine is
switched off requires applying more strength
to the brake pedal. Risk of accident!
● Press down on the clutch pedal when stop-
ping and brak
ing with a manual gearbox,152

Driving
petrol engine vehicle at low speed. Other-
wi
se, the br
ake servo might not work proper-
ly. Risk of accident!
● In the event of damage to the standard
front s
poiler or where a different front spoil-
er, wheel trims, etc. are subsequently fitted,
make sure the air vent to the brakes on the
front wheels is not blocked. Otherwise, brak-
ing operations may be impaired. Risk of acci-
dent!
● Always fully release the handbrake. If it is
only p
artially released, this will cause over-
heating of the rear brakes, which can impair
the function of the brake system. Risk of acci-
dent!
● Never leave children unsupervised in the
vehicl
e. They could release the handbrake or
move the gear lever. The vehicle could start
moving. Risk of accident!
● Insufficient fuel can cause the engine to run
irregu
larly or to switch off. Brake assist sys-
tems could be impaired. Risk of accident!
● Always adjust your driving style to suit visi-
bility
, the weather and road and traffic condi-
tions. The best vehicle safety offered by
brake assist systems must never encourage
you to run greater risks. Risk of accident! CAUTION
● Ob ser

ve the information concerning new
brake pads ››› page 161.
● Where braking is not necessary, do not
wear do
wn the brake pads by pressing down gently on the brake pedal. This causes the
brak
e

s to overheat, increasing their wear and
increasing braking distances.
● To ensure the brake assist systems work
properly, a
ll wheels must be fitted with tyres
approved by the manufacturer. Note
● If y

ou brake suddenly and the brake system
control unit regards the situation as hazard-
ous for the drivers behind you, the brake
lights will begin to flash automatically. After
reducing speed to approximately 10 km/h (6
mph) or stopping the vehicle, the brake lights
will stop flashing and the hazard warning
lights will switch on. The hazard warning
lights are automatically switched off when
you accelerate or restart the vehicle.
● On long, steep gradients, reduce your
speed and ch
ange to a lower gear (manual
gearbox) or move the selector lever to a lower
gear position (automatic gearbox). This uses
the force of the engine and the brakes do not
suffer as much. If you still have to brake, do
so intermittently, pressing down repeatedly
on the brake pedal.
● Vehicle modifications (e.g. to the engine,
brake
s, frame or a combination of wheels and
tyres) could impair the brake assist systems
››› page 192, Accessories and modifications
to the vehicle .
● In the event of a fault in the ABS system,
the ESC, T
CS and EDL are switched off auto- matically. A fault in the ABS is indicated by

Operation
Brakes Wear
The rat
e of
wear of the brake pads depends
on the driving style and on the way in which
the vehicle is used. The brake pads will wear
more quickly if you use your vehicle frequent-
ly in urban traffic and short trips or drive in a
sporty style. Under these demanding condi-
tions, visit your specialised service, even be-
fore the scheduled service date, so that the
thickness of the brake pads can be meas-
ured.
Wet roads or road salt
If brakes are wet or frozen, or if you are driv-
ing on roads which have been gritted with
salt, braking power may set in later than nor-
mal. Dry the brakes as soon as possible by
braking repeatedly.
Corrosion
Long periods of inactivity and little use can
lead to rust on the brake discs and dirt on the
brake pads. Where the brake system is sub-
jected to light stress or in the case of corro-
sion, clean the brake discs by braking fully
several times at a high speed.
Brake system fault
If you notice that the braking distance sud-
denly increases and the brake pedal can be
pressed down more fully, there may be a fault in the brake system. Visit a specialised serv-
ice immedi
at

ely and adjust your driving style
to the extent of the damage and to limit the
effect of the brakes.
Low brake fluid level
Insufficient brake fluid could cause faults in
the brake system. The brake fluid level is con-
trolled electronically ››› page 153, Control
lamp.
Brake servo
The brake servo supplements the pressure
you exert on the brake pedal. The brake servo
only works when the engine is running.

Control lamp
The warning lamp lights up when the hand-
brake is applied with the ignition on .
Additionally, driving the vehicle at speeds ex-
ceeding 6 km/h (4 mph) for at least 3 sec-
onds produces an audible warning.
The informative display indicates: Release the handbrake!
Braking and stability systems Electronic
Stability Control (ESC) The ESC system increases control of the vehi-
c
l
e in emer

gency situations, e.g. during a
sudden change in direction. Depending on
the driving conditions, it reduces the risk of
skidding and increases driving stability.
The system uses the steering wheel angle
and road speed to calculate the changes of
direction desired by the driver, and constant-
ly compares them with the actual behaviour
of the vehicle. When irregularities occur, for

Economical and environmentally-
friendly drivin
g Fuel consumption, environmental pollution
and we
ar t

o the engine, brakes and tyres de-
pends in large part on your driving style. By
adopting an economical driving style and an-
ticipating the traffic situation ahead, you can
easily reduce fuel consumption by 10-15%.
Some tips on how to help you reduce pollu-
tion while saving money are listed below.
Drive anticipating the traffic situation
A vehicle uses most fuel when accelerating.
When you anticipate situations, you have to
brake less often and, thus, accelerate less. If
it is possible, let the vehicle roll with a gear
engaged, for example, if you see a red light
ahead. The braking effect achieved in this
way helps to reduce the wear of brakes and
tyres; emissions and fuel consumption are
reduced to zero (disconnection due to iner-
tia).
Change gear early to save energy
An effective way of saving fuel is to change
up quickly through the gears. Running the
162

Operation
●
It i s
recommended that you close the win-
dows when driving at more than 60 km/h
(37 mph)
● Do not drive with your foot resting on the
clutc
h pedal,, as the pressure can make the
plate spin, more fuel will be used and it can
burn the clutch plate lining, causing a serious
fault.
● Do not hold the vehicle on a hill with the
clutc
h, use the foot brake or hand brake, us-
ing the latter to start. The fuel consumption
will be lower and you will prevent the clutch
plate from being damaged.
● On descents, use the engine brake, chang-
ing to the g
ear that is more suitable for the
slope. Fuel consumption will be “zero” and
the brakes will not suffer. Engine management and ex-

t gas purification system
Introduction WARNING
● Bec au

se of the high temperatures which
can occur in the exhaust purification system
(catalytic converter or diesel particulate fil-
ter), do not park the vehicle where the ex-
haust can come into contact with flammable
materials under the car (e.g. on grass or at
the forest edge). Fire hazard! ●
Do not ap p

ly wax underneath the vehicle
around the area of the exhaust system: Fire
hazard! Note
While the control lamps , ,  or  r
e-
m ain lit, ther

e may be engine problems, fuel
consumption may increase and the engine
may lose power. Catalytic converter
An exhaust gas emission control system (cat-
alytic
c
on

verter) that functions perfectly is vi-
tally important for vehicle operation that re-
spects the environment.
Please observe the following indications:
● Refuel only using unleaded petrol in petrol
engine v
ehicles ››› page 200.
● Do not add too much oil to the engine
›››
page 207, Checking engine oil level .
● Do not switch off the ignition while driving.
If y
ou are required to drive in a country where
unleaded fuel is not available, when return-
ing to a country where using a catalytic con-
verter is obligatory, the catalytic converter
must be replaced. CAUTION
● Never c omp

letely empty the tank! An irreg-
ular fuel supply can cause ignition faults,
which can result in damage to a substantial
amount of engine parts and the exhaust sys-
tem.
● Refuelling just once with leaded petrol dis-
able
s the exhaust system! Particulate filter  (diesel
en
gines) The diesel engine particulate filter eliminates
mo
s
t

of the soot from the exhaust gas sys-
tem. Under normal driving conditions, the fil-
ter cleans itself. The diesel particulate filter is
cleaned automatically without need for indi-
cation by the warning lamp . This may be
noticed because the engine idle speed in-
creases and an odour may be detected.
If automatic filter purification cannot be car-
ried out (because only short trips are taken,
for example), soot will accumulate on the fil-
ter and the Diesel particulate filter warning
lamp will  switch on.
Facilitate the automatic filter cleaning proc-
ess by driving in the following manner: drive
for approximately 15 minutes at a minimum
speed of 60 km/h (37 mph) in 4th or 5th gear
(automatic gearbox: gear S). Maintain the en-
gine speed at approximately 2,000 rpm. The

Driving through water. To prevent the vehicle from being damaged
when driv
in
g thr

ough water (i.e. flooded
roads), please observe the following:
● Determine the depth of the water before
entering.
Water can reach a maximum height
of below the door sill ››› Fig. 180.
● Drive at a maximum pace of walking speed.
Driving at
a higher speed can cause a wave
in front of the vehicle, which can cause water
to enter the engine air intake system or other
parts of the vehicle.
● Never stop in the water, never reverse and
never st
op the engine.
● Before driving through water deactivate the
Start
-Stop system ››› page 181. WARNING
● Drivin g thr

ough water, dirt and mud can re-
duce braking capability and prolong the brak-
ing distance – Risk of accident!
● Do not carry out any sudden or strong brak-
ing manoeu
vres after driving through water.
● Clean and dry the brakes as soon as possi-
ble af
ter driving through water by breaking
intermittently. Carry out braking in order to
dry the brakes and clean the brake discs only
if traffic so permits. Do not put other drivers
at risk. CAUTION
● In the event of

driving through water, parts
of the vehicle can be seriously damaged,
such as the engine, gearbox, catalytic con-
verter, suspension or the electrical system.
● Oncoming vehicles that drive through wa-
ter can c
ause waves that exceed your vehi-
cle's permitted level for driving through wa-
ter.
● There may be pot-holes mud or rocks under
the water th
at can hinder or prevent driving
through water.
● Do not drive through salt water. The salt
can cau
se rust. All components that are ex-
posed to salt water must be rinsed immedi-
ately with fresh water. Note
After driving through water we recommend
that

you contact a specialised service for an
inspection. Preventing damage to the vehicle
In order to prevent damage to the vehicle,
tak
e s

pecial care:
● on roads that are in poor condition,
● when mounting kerbs,
● when approaching very steep ramps, etc.,
● with the parts of the vehicle situated on the
low er p

art of the vehicle, i.e. the spoiler, the
exhaust pipe.
This applies especially to vehicles with a very
low suspension (sport) and when the vehicle
is fully loaded. 166

Monitoring system Front As-
sis
t*
Introduction The Front Assist Monitoring system helps to
pr
ev
ent

rear collisions.
The Front Assist can warn the driver of colli-
sion hazards, prepare the vehicle for emer-
gency braking in case of danger, assist the
driver on braking and cause automatic brak-
ing.
The Front Assist is not a replacement for
driver awareness.
Distance warning
If the system detects that safety is endan-
gered by the proximity of the vehicle in front,
it may warn the driver by means of a message
on the instrument panel when driving at a
speed of between approximately 60 km/h
(37 mph) and 210 km/h (130 mph)
››› Fig. 188.
The warning moment varies depending on
the traffic situation and driver behaviour. Advance warning
If the sys

tem detects a possible collision with
the vehicle in front, it may warn the driver by
means of an audible warning and an indica-
tion on the instrument panel when driving at
a speed of between approximately 30 km/h
(18 mph) and 210 km/h (130 mph)
››› Fig. 188.
The warning moment varies depending on
the traffic situation and driver behaviour. At
the same time, the vehicle will prepare for a
possible emergency braking ››› .
C ritic
a

l warning
If the driver fails to react to the advance
warning, the system may actively intervene in
the brakes when driving at a speed of be-
tween approximately 30 km/h (18 mph) and
210 km/h (130 mph), generating a brief jolt
to warn of the imminent collision.
Automatic braking
If the driver also fails to react to the advance
warning, the system may brake the vehicle
automatically, by progressively increasing
braking effect driving at a speed of between
approximately 5 km/h (3 mph) and 210 km/h
(130 mph). By reducing speed in case of a
possible collision, the system may contribute
to reducing the consequences of an accident. Front assist
If the Front

Assist notices that the driver is
not braking sufficiently in case of a collision
hazard, the system can increase braking ef-
fect and thus avert the collision when driving
at a speed of between approximately 5 km/h
(3 mph) and 210 km/h (130 mph). Front as-
sist only acts while the brake pedal is press-
ed down hard. WARNING
The intelligent technology in the Front Assist
cannot c

hange the laws of physics. The driver
is always responsible for braking in time. If
the Front Assist issues a warning, then, de-
pending on the traffic circumstances, you
must brake immediately or dodge the obsta-
cle.
● Adapt your speed and safe distance to the
vehicl
e in front of you at all times to suit visi-
bility, weather, road and traffic conditions.
● The Front Assist alone cannot avoid acci-
dents and seriou
s injuries.
● In complex driving situations, the Front As-
sis
t may issue unnecessary warnings and in-
tervene unnecessarily in braking, such as in
traffic islands.
● If the operation of the Front Assist is im-
paired, f
or example, by dirt or because the ra-
dar sensor has lost its settings, the system
may issue unnecessary warnings and inter-
vene inopportunely in the braking. 176

Operation
● Mi s
aligned
vehicles.
● Vehicles crossing the other's path.
● Vehicles approaching in the opposite direc-
tion.
● Special loads and accessories of other ve-
hicle
s that jut out over the sides, backwards
or over the top.

The C ity
Emergency braking function picks
up, at speeds between 5 km/h (3 mph) and
30 km/h (19 mph) approximately, the traffic
situation in front of the vehicle up to a dis-
tance of about 10 m.
If the system detects a possible collision with
a vehicle in front of it, the vehicle prepares
for a possible emergency braking ››› .
If the driv
er f

ails to react to a possible colli-
sion, the system may brake the vehicle auto-
matically, by progressively increasing braking
effect driving to reduce speed in the event of
a collision. The system can thus help to re-
duce the consequences of an accident.
Status display
Automatic deceleration by means of the City
Emergency braking function is displayed on
the instrument panel by means of the ad-
vance warning ››› Fig. 192 1)
. WARNING
The smart technology included in the City
Emerg ency

braking function cannot defy the laws of physics. The driver is always respon-
sib
l

e for braking in time.
● Adapt your speed and safe distance to the
vehicl
e in front of you at all times to suit visi-
bility, weather, road and traffic conditions.
● The City Emergency braking function alone
cannot pr
event accidents or serious injury.
● In complex driving situations, the City
Emergency
braking function may issue unnec-
essary warnings and intervene inopportunely
in braking, such as in work areas or if there
are metal rails.
● If the operation of the City Emergency brak-
ing fu
nction is impaired, for example, by dirt
or because the radar sensor has lost its set-
tings, the system may issue unnecessary
warnings and intervene inopportunely in the
braking.
● During driving, the City Emergency braking
function doe
s not react to people or animals
or vehicles crossing your path or which ap-
proach you head-on in the same lane. Note
● When the City Emer

gency braking function
causes a braking, the brake pedal is “hard-

Towing bracket device
Driving with a trailer Exterior mirrors
Check
whether
you can see enough of the
road behind the trailer with the standard rear
vision mirrors. If this is not the case, you
should have additional exterior mirrors fitted.
Observe the relevant statutory requirements
of the country you are in.
Headlights
Before starting a journey, also check the
headlight beam settings with the trailer
hitched up. Adjust the headlight range set-
tings if necessary ›››
page 117, Main light
range control .
Driving speed
For your own safety do not drive faster than
the maximum permitted speed indicated on
the trailer.
At all times, immediately reduce speed if you
detect the slightest swaying movement of the
trailer. Never try to “return the trailer to a
straight position” by accelerating.
Brakes
Brake in due course! If the trailer has an over-
run brake, apply the brakes gently at first and
then, firmly. This will prevent the jerking that
can be caused by locking of trailer wheels.
Change to a lower gear in good time before descending a slope in order to take advant-
age of
the en

gine brake.
The trailer is incorporated into the vehicle's
anti-theft alarm system:
● When the vehicle has a factory-fitted anti-
theft al
arm and a towing bracket.
● When the trailer is electrically connected to
the vehic
le via the towing bracket socket.
● When the vehicle electrical device and the
tow
ing bracket are operational.
● When the vehicle is locked and the vehi-
cle's
anti-theft alarm device is activated.
Once the electrical connection is interrupted
with the vehicle trailer locked, the alarm
sounds.
Always switch off the vehicle anti-theft alarm
device before connecting or disconnecting a
trailer. The vehicle anti-theft alarm device
could cause the alarm to sound ››› page 112,
Anti-theft alarm system*.
Engine overheating
In the event that the coolant temperature
gauge needle moves to the right section of
the scale or to the red area, immediately re-
duce speed. If the control lamp  flashes on
the general instrument panel, stop the vehi-
cle and switch off the engine. Wait several
minutes and check the coolant level in the
tank ››› page 208. Please observe the following indications
›››
page 208, Control lamp .
The coolant temperature can be reduced by
switching on the heating. WARNING
● Adjus t

your speed to suit the road and traf-
fic conditions.
● An electrical installation that is connected
incorrectly
or by non-specialised personnel
can prevent the connection of the current to
the trailer and cause faults in the operation of
the electrical system throughout the entire
vehicle, leading to accidents and serious in-
jury.
● All electrical work must be carried out only
by s
pecialised services.
● Never directly connect the trailer electrical
device t
o the electrical sockets of the reverse
driving lights or other sources of electrical
current. CAUTION
● Av oid c

orners, and sudden and sharp brak-
ing.
● Once the trailing arm has been removed,
plac
e the corresponding cover on the hole of
the fastening point. This prevents dirt from
entering the hole – see the trailer system as-
sembly manual. » 185
