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, pet- rol engine vehicle at low speed. Otherwise,
the brak
e ser
vo might not work properly. 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 163.156
Driving
●
Where br ak
ing is not necessary, do not
wear down the brake pads by pressing down
gently on the brake pedal. This causes the
brakes 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 193, Accessories and modifications
to the vehicle . ●
In the event of
a fault in the ABS system,
the ESC, TCS and EDL are switched off auto-
matically. A fault in the ABS is indicated by
the ››› page 101 warning lamp. 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
sever
al
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 immediately 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 99, Brake sys-
tem .
Brake servo
The brake servo supplements the pressure
you exert on the brake pedal. The brake servo
only works when the engine is running.

slope, the handbrake should be firmly ap-
p lied bef
or
e moving the selector lever to the
park position. This reduces the load on the
lock mechanism while making it easier to
move the selector lever from position P.
If, while the vehicle is moving, the selector
lever is accidentally moved to position N, re-
lease the accelerator and wait for the engine
to idle before moving it back into position. WARNING
● Never pr e
ss the accelerator when selecting
the automatic gearbox operating mode when
the vehicle is stationary. Risk of accident!
● Never move the selector lever to positions
R or P when driving. Ri
sk of accident!
● If the vehicle is to be stopped with a gear
selected and the en
gine idling (e.g. waiting
or moving slowly at traffic lights), press down
on the brake pedal because the transmission
is not entirely interrupted when the engine is
idling and the vehicle will tend to start mov-
ing.
● Apply the handbrake firmly and put the se-
lector l
ever in position P before opening the
bonnet and working on the vehicle with the
engine running. Risk of accident! Strictly fol-
low the safety instructions ››› page 203, En-
gine compartment.
● When stopping on a slope (hill), try not to
stop the
vehicle from moving by pressing the
“accelerator” with a gear selected. This could
overheat the clutch. If the clutch risks being burnt due to this force, it would switch off
and the v
ehic
le could move backwards. Risk
of accident!
● If you have to stop on a hill, press down on
the brake ped
al to stop the vehicle from mov-

Operation
Driving programmes Your vehicle is equipped with an electronical-
ly-c
ontr
olled automatic gearbox. Shifting up
or down depends on the programme selec-
ted.
For a calm driving style, the gearbox uses the
most economic programme. The gearbox
shifts up as quickly as possible and shifts
down as late as possible, thus increasing
driving economy.
With a sporty driving style , characterised by
sudden acceleration, heavy acceleration,
speeds that often increase and decrease and
maximum speed, the gearbox adapts to this
driving style when the accelerator is pressed
down fully (kick-down) by shifting down as
quickly as possible and can even shift down
by several gears at once.
Selecting the best driving programmes is an
endless job. Regardless of this, the driver can
also make the gearbox switch to a more dy-
namic gear shift programme by pressing the
accelerator quickly. This makes the automatic
gearbox shift down into a lower gear than the
one that would normally apply to the current
speed, allowing for more rapid acceleration
(e.g. to overtake another vehicle) without
having to press the accelerator until the kick-
down position. On shifting up in a corre-
sponding driving style, the gearbox returns to
the original programme. When driving along mountain roads, the
ge
arbo
x adapts to the gradients. This avoids
having to frequently change gears when driv-
ing uphill. In Tiptronic mode, it is possible to
shift down manually when driving downhill to
use the braking effect of the engine.
Backup programme A back-up programme exists in case of faults.
In the event
of
a fault in the gearbox electron-
ics, it will continue to work in one of the cor-
responding back-up programmes. All seg-
ments of the screen are lit up or switched off.
The fault can be seen as follows:
● The gearbox only engages certain gears
● Reverse gear R cannot be en
gaged
● The manual gearbox switches off in the
back
-up programme Note
If the gearbox switches to the back-up pro-
gramme, v
isit an Authorised Service as soon
as possible to solve the problem. Gearbox malfunctions

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
164
Operation
Save electricity
The en gine activ
at
es the alternator, which
produces electricity. With the need for elec-
tricity, fuel consumption also increases. Be-
cause of this, always turn off electrical devi-
ces when you do not need them. Examples of
devices that use a lot of electricity are: the
fan at high speeds, the rear window heating
and the seat heaters*. Note
● If y
ou vehicle has Start-Stop, it is not rec-
ommended to switch this function off.
● It is recommended to close
the windows
when driving at more than 60 km/h
● 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. Wading and driving off-road

● 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
