se. This position is shared by all pro-
grammes for reversing.
Selecting the sport programme – Move the lever to position S.
If you select sport programme S, the pro-
gr amme i

s designed for sport mode, that is,
a programme which changes up at higher en-
gine speeds to use the full power of the en-
gine. This programme is not recommended
for use on the motorway or in the city.
Selecting the manual programme (Tiptronic)
This programme allows driving similar to a
manual gearbox.
This programme may be accessed using the
selector lever or from the steering wheel con-

Starting
– Start the engine with the selector lever in
position P
or

Driving – Press and hold the brake pedal. –
Holding down the lock button (button on
the selector lever), select R or D.
– Rel

ease the lever and wait a little for the
gearbox to engage the gear (a slight move-
ment can be felt).
– Release the brake and press the accelerator
››› .
Stopping briefly – If stopping for a short time, keep the vehi-
cle stationary by pressing the foot brake
hard to prevent the vehicle moving back-
wards on a slope or “creeping” forwards,
e.g. at traffic lights. The selector lever does
not need to be put into the positions P or N
f or thi

s.
– Do not press the accelerator.
Parking
– Press and hold the brake pedal until the ve-
hicle comes to a standstill ››› .
– Apply the handbrake.
– By pressing the lock button down, move
the selector lever to P
and release the lock
b

utton.
Driving up and down hills
– Press the selector lever from position “D”
to the right into the tiptronic selector gate. –
Lightly press the selector lever back to
change down.
Holding the car on a hill – The brake must be always pressed down to
prevent the vehicle from “rolling back-
wards” ››› . Do not try to prevent the vehi-
cle from “rolling backwards” by increasing
the engine speed while a range of gears is
selected.
Starting the vehicle up hills
– Apply the handbrake.
– With a selected gear, accelerate slowly and
at the same time, release the handbrake.
The steeper the slope, the lower the needed
gear. This increases the braking effect of the
engine. For example, when driving down a
very steep slope in third gear. If the engine
brake effect is not enough, the vehicle will
speed up. The automatic gearbox automati-
cally changes up to prevent the engine over-
revving. Use the foot brake to reduce speed
and change into 3rd gear using Tiptronic*
››› .
Your vehicle has an automatic interlock
which prevents the selector lever from being
put into a position for driving forwards or in
reverse from positions P or N
if the brake
ped

al is not depressed.

When the warning lamp next to the selector
lever lights up, press the brake pedal. This is
necessary when the automatic gearbox selec-
tor lever is moved out of positions P or N
. A
text message or instructions to perform nec-
essary operations may appear on the instru-
ment panel. WARNING
● As a driver, you should never leave your ve-
hicle if the engine is running and a gear range
is engaged. If you have to leave your vehicle
while the engine is running, you must apply
the parking brake and put the selector lever
in position P.
● If the engine is running and if D or R is en-
gaged, you will need to hold the car on the
foot brake. The car will creep forward as the
power transmission is not fully interrupted
even when the engine is idling.
● Never accelerate when moving the selector
lever or you may cause an accident.
● Never move the selector lever to R or P
when driving. Risk of accident!
● Before driving down a long, steep slope, it
is advisable to reduce speed and change into
a lower gear. ●
If you stop the vehicle up hill, always hold
the foot brake strongly depressed down to
stop it from rolling back.
● Never allow the brake to rub and do not use
the brake pedal too often or for long periods.
Constant braking will cause the brakes to
overheat and will considerably reduce the
brake effect. This increases the braking dis-
tance and could cause the brake system to
fail.
● Never allow the car to roll down a gradient
with the gear in neutral N, or in selector lever
position D, even if the engine is not running. CAUTION
● If you stop the vehicle up hills, do not at-
tempt to stop it from rolling back by depress-
ing the accelerator when a gear has been se-
lected. Otherwise, the automatic gearbox
may overheat causing damage. Pull the hand-
brake up or fully depress the brake pedal to
prevent the vehicle from rolling away.
● If you allow the vehicle to roll when the en-
gine is not running, or with the selector lever
in position N, a lack of lubrication in the auto-
matic gearbox will damage it. Changing gear in Tiptronic mode*

Operation
●
Do not apply additional underseal or anti-
corrosion coatings to the exhaust pipes, cata-
lytic converter or the heat shields on the ex-
haust system. These materials could catch
fire when the vehicle is being driven. CAUTION
Never run the fuel tank completely dry be-
cause the irregularity of the fuel supply may
cause ignition problems. This allows unburnt
fuel to enter the exhaust system, which could
cause overheating and damage the catalytic
converter. For the sake of the environment
Even when the emission control system is
working perfectly, there may be a smell of
sulphur from the exhaust gas under some
conditions. This depends on the sulphur con-
tent of the fuel used. Quite often the problem
can be solved by changing to another brand
of fuel. Diesel engine particulate filter*
Fig. 130
Vehicle data sticker on back cover of
the Maintenance Programme. Your vehicle is fitted with a DPF (Diesel partic-
ulate filter) if the vehicle data sticker (back
cover of the “Maintenance Programme)” lists
the PR code 7GG or 7MG
››› Fig. 130 .
The die sel
engine particulate filter eliminates
most of the soot from the exhaust gas sys-
tem. Under normal driving conditions, the fil-
ter cleans itself. If this is not possible (for ex-
ample, multiple short trips) the filter will be
obstructed by soot and  the diesel engine
particulate filter warning lamp will light up.
This does not represent a fault, it is a warning
that indicates that the filter has not been
able to regenerate automatically and that you
must perform a cleaning cycle, as indicated
in ››› page 41
. WARNING
● The diesel engine particulate filter may
reach extremely high temperatures; the vehi-
cle should be parked so that the exhaust pipe
does not come into contact with flammable
materials underneath the vehicle. Otherwise
there is a risk of fire. CAUTION
● Your vehicle is not designed to use biodie-
sel fuel. Never, under any circumstances re-
fuel with biodiesel. The use of biodiesel fuel
could damage the engine and the fuel sys-
tem. The addition of biodiesel to diesel by
the diesel producer in accordance with stand-
ard EN 590 is authorised and will not cause
damage to the engine or the fuel system.
● Using diesel fuel with a high sulphur con-
tent may significantly reduce the useful life of
the diesel particulate filter. Your Technical
Service will be able to tell you which coun-
tries have diesel with a high sulphur content. Economical and environmentally
friendly driving
Fuel consumption, environmental pollution
and wear to 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%.
132

Driving
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
ahe a
d. 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
engine at high rpm in the lower gears uses
an unnecessary amount of fuel.
Manual gearbox: shift up from first to second
gear as soon as possible. We recommend
that, whenever possible, you change to a
higher gear upon reaching 2000 rpm. Follow
the “recommended gear” indication that ap-
pears on the instrument panel ››› page 47.
Avoid driving at high speed
We advise you not to drive at the top speed
permitted by the vehicle. Fuel consumption,
exhaust emissions and noise levels all in- crease very rapidly at higher speeds. Driving
at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine
when waiting in a traffic jam, at level cross-
ings or at traffic lights with a long red phase.
The fuel saved after only 30 - 40 seconds is
greater than the amount of fuel needed to re-
start the engine.
The engine takes a long time to warm up
when it is idling. Mechanical wear and pollu-
tant emissions are also especially high dur-
ing this initial warm-up phase. It is therefore
best to drive off immediately after starting
the engine. Avoid running the engine at high
speed.
Periodic maintenance
Periodic maintenance work guarantees that,
before beginning a journey, you will not con-
sume more than the required amount of fuel.
A well-serviced engine gives you the benefit
of
improved fuel efficiency as well as maxi-
mum reliability and an enhanced resale val-
ue.
A badly serviced engine can consume up to
10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of
polluting exhaust gases, the engine and the exhaust gas filtration systems should reach
the optimum operating temperature.
With the en

gine cold, fuel consumption is
proportionally higher. The engine does not
warm up and fuel consumption does not nor-
malise until having driven approximately four
kilometres. This is why we recommend avoid-
ing short trips whenever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an ad-
equate pressure saves fuel. If the tyre pres-
sure is just one bar (14.5 psi / 100 kPa) too
low, fuel consumption can increase by as
much as 5%. Due to the greater rolling resist-
ance, under-inflation also increases tyre wear
and impairs handling.
The tyre pressures should always be checked
when the tyres are cold.
Do not u

se winter tyres
all year round as they
increase fuel consumption by up to 10%.
Avoid unnecessary weight
Given that every kilo of extra weight
will in-
crease the fuel consumption, it is advisable
to always check the luggage compartment to
make sure that no unnecessary loads are be-
ing transported.
A roof rack is often left in place for the sake
of convenience, even when it is no longer
needed. At a speed of 100 km/h (62 mph) »

Advice
Operation
Safety

Operation
and 120 km/h (75 mph) your vehicle will use
about 12% more fuel as a result of the extra
wind resistance caused by the roof rack even
when it is not in use.
Save electricity
The engine activates the alternator, which
produces electricity. With the need for elec-
tricity, fuel consumption is also increased.
Because of this, always turn off electrical de-
vices 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
or the seat heaters*. Note
● If you vehicle has Start-Stop, it is not rec-
ommended t o sw
itch 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
clutch pedal,, as the pressure can make the
pl

ate 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
clutch, 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 gear that is more suitable for the slope. Fuel consumption will be “zero” and
the brakes will not suffer.
Driver assistance systems
Braking and stability systems Electronic Stability Control (ESC)* Fig. 131
Detailed view of the centre console:
ESC switch. This Electronic Stability System reduces the
risk of skidding and improves the vehicle's
stability and ability to hold the road.
Electronic Stability Control (ESC) includes the
electronic differential lock (EDL), the traction
control system (TCS), the brake assist system
(BAS) and the trailer stabilisation programme
(TSP). The ESC works together with the ABS.
Both control lamps will light up if the ESC or
ABS systems are faulty.
The ESC system is started automatically
when the engine is started.
134

Driver assistance systems
The ESC system is always active and cannot
be switched off. The ESC switch only switches
the ASR off.
The ASR can be deactivated when wheel spin
is desirable.
For example:
● When driving with snow chains.
● When driving in deep snow or on loose sur-
faces.
● When the vehicle is stuck, to rock it back-
wards and forwards.
Press the button to switch the ASR back on
when you no longer need wheel spin.
Electronic Stability Control (ESC)*
The ESC reduces the risk of skidding by brak-
ing the wheels individually.
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
example, if the vehicle begins to skid, the
ESC brakes the appropriate wheel automati-
cally.
The forces acting on the braked wheel bring
the vehicle back to a stable condition. If the
vehicle tends to oversteer (the rear end
slides out), the system will act on the front
wheel on the outside of the turn. Steering manoeuvre recommendations
This is a complementary safety function in-
cluded in the ESC. This function aids the driv-
er to better stabilize the vehicle in a critical
situation. For example, in case of sudden
braking on a surface with varied adherence,
the vehicle will tend to destabilise its trajec-
tory to the right or to the left. In this case, the
ESC recognises the situation and assists the
driver with a counter steering manoeuvre
from the power steering.
This function simply provides the driver with
a recommended manoeuvre in critical situa-
tions.
The vehicle does not steer itself with this
function, the driver has full control of the ve-
hicle at all times.
WARNING
● Remember that not even the ESC can defy
the laws of physics. This should be kept in
mind, particularly on slippery and wet roads
and when towing a trailer.
● Always adapt your driving style to suit the
condition of the roads and the traffic situa-
tion. The greater safety provided by the ESC
should not encourage you to run any risks. CAUTION
● To ensure that the ESC works correctly, all
four wheels must be fitted with the same
tyres. Any differences in the rolling radius of the tyres can cause the system to reduce en-
gine power when this is not desired.
● Any modifications made to the vehicle (for
example, to the engine, brake system, run-
ning gear or to the combination of wheels
and tyres) may affect the operation of the
ABS, EDL, ESC and ASR. Electronic differential lock (EDL)*
EDL helps the vehicle to start moving, accel-
erate and climb a gradient in slippery condi-
tions where this may otherwise be difficult or
even impossible.
It uses the ABS sensors to monitor the speed
of the driven wheels. In case of an EDL fault,
the warning light for ABS lights up
››› page 41 .
At s
peeds of up to approximately 80 km/h
(50 mph), it is able to balance out differences
in the speed of the driven wheels of approxi-
mately 100 rpm/min caused by a partially
slippery road surface. It does this by braking
the wheel which has lost traction and distrib-
uting more driving force to the other driven
wheel via the differential.
To prevent the disc brake of the braking
wheel from overheating, the EDL cuts out au-
tomatically if subjected to excessive loads.
The vehicle will continue to function normally »

without EDL. For this reason, the driver is not
informed that the EDL has been switched off.
The EDL will switch on again automatically
when the brake has cooled down. WARNING
● When accelerating on a slippery surface,
for example on ice and snow, press the accel-
erator carefully. Despite EDL, the driven
wheels may start to spin. This could impair
the vehicle's stability.
● Always adapt your driving style to suit road
conditions and the traffic situation. Do not let
the extra safety afforded by EDL tempt you in-
to taking any risks when driving, this can
cause accidents. CAUTION
Modifications to the vehicle (e.g. to the en-
gine, the brake system, running gear or any
components affecting the wheels and tyres)
could affect the efficiency of the EDL
››› page 147. Hydraulic Brake Assist (HBA)*
The function (Hydraulic Brake Assist HBA) is
only included in vehicles with ESC.
In an emergency, most drivers brake in time,
but not with maximum force. This results in
unnecessarily long braking distances. This is when the brake assist system comes
into action. When pressing the brake pedal
rapidly, the assistant interprets it as an emer-
gency. It very quickly builds up the full brake
pressure so that the ABS can be activated
more quickly and efficiently, thus reducing
braking distance.
Do not reduce the pressure on the brake ped-
al, since the brake assist system switches off
automatically as soon as you release the
brake.
Emergency braking warning
If the vehicle is braked suddenly and continu-
ously at a speed of more than 80 km/h, the
brake light flashes several times per second
to warn vehicles driving behind. If you contin-
ue braking, the hazard warning lights will
come on automatically when the vehicle
comes to a standstill. They switch off auto-
matically when the vehicle starts to move
again.
WARNING
● The risk of accident is higher if you drive
too fast, if you do not keep your distance from
the vehicle in front, and when the road sur-
face is slippery or wet. The increased acci-
dent risk cannot be reduced by the brake as-
sist system.
● The brake assist system cannot defy the
laws of physics. Slippery and wet roads are
dangerous even with the brake assist system! Therefore, it is essential that you adjust your
speed to suit the road and traffic conditions.
Do not let the extra safety features tempt you
into taking any risks when driving.
Anti-lock brake system (ABS)
The anti-lock brake (ABS) system prevents
the wheels from locking during braking and
is an important part of the vehicle's active
safety system.
How the ABS works
If one of the wheels turns too slowly in rela-
tion to the vehicle's speed, and is close to
locking, the system will reduce the braking
pressure to this wheel. The driver is made
aware of this control process by a
pulsating
of the brake pedal and audible noise. This is
a deliberate warning to the driver that one or
more of the wheels is tending to lock and the
ABS control function has intervened. In this
situation it is important to keep the brake
pedal fully depressed so the ABS can regu-
late the brake application. Do not “pump”.
If you brake hard on a slippery road surface,
the best possible control is retained as the
wheels do not lock.
However, ABS will not necessarily guarantee
shorter braking distances in all conditions.
Br ak
ing distance could even be further if you
136

Driver assistance systems
brake on gravel or on fresh snow on a
slippery surface. WARNING
● The anti-lock brake system cannot defy the
laws of physics. Slippery and wet roads are
dangerous even with ABS! If you notice that
the ABS is working (to counteract locked
wheels under braking), you should reduce
speed immediately to suit the road and traffic
conditions. Do not let the extra safety fea-
tures tempt you into taking any risks when
driving.
● The effectiveness of ABS is also determined
by the tyres fitted ››› page 175.
● If the ru
nning gear or brake system is modi-
fied, the effectiveness of the ABS could be se-
verely limited. Drive wheel traction control system
(ASR)
The traction control system prevents the driv-
en wheels from spinning when the vehicle is
accelerating.
Description and operation of the traction
control system during acceleration (ASR
On front-wheel drive vehicles, the ASR sys-
tem intervenes, reducing engine power and
preventing the driven wheels from slipping
during acceleration. The system works in the entire speed range in conjunction with ABS.
If a failure occurs in the ABS, the ASR will al-
so stop working.
TCS helps the car to start moving, accelerate
and climb a gradient in slippery conditions
where this may otherwise be difficult or even
impossible.
The ASR automatically switches on when the
engine is started. If necessary, it may be
turned on or off by briefly pushing the button
on the centre console.
When the ASR is switched off, the
 OFF warning lamp will light up. The ASR should
normally be left on. Only in exceptional cir-
cumstances, when slipping of the wheels is
desired, should it be disconnected.
●
With compact temporary spare wheel.
● When using the snow chains.
● When driving in deep snow or on soft ter-
rain.
● When the vehicle is bogged-down, to free it
by “rocking.”
The ASR should be switched on again as
soon as possible. WARNING
● Remember that not even the ASR can defy
the laws of physics. This should be kept in
mind, particularly on slippery and wet roads
and when towing a trailer. ●
Always adapt your driving style to suit the
condition of the roads and the traffic situa-
tion. The greater safety provided by the ASR
should not encourage you to run any risks. CAUTION
● To ensure that the ASR works correctly,
identical tyres should be fitted on all four
wheels. Any differences in the rolling radius
of the tyres can cause the system to reduce
engine power when this is not desired.
● Any modifications made to the vehicle (for
example, to the engine, brake system, run-
ning gear or to the combination of wheels
and tyres) may affect the operation of the
ABS and ASR. XDS*
When taking a curve, the driveshaft differen-
tial mechanism allows the outer wheel to turn
at a higher speed than the inner wheel. In
this way, the wheel that is turning faster (out-
er wheel) receives less drive torque than the
inner wheel. This may mean that in certain
situations the torque delivered to the inner
wheel is too high, causing the wheels to
spin. On the other hand, the outer wheel is
receiving a lower drive torque than it could
transmit. This causes an overall loss of lateral
grip on the front axle, resulting in understeer
or “lengthening” of the trajectory.

Technical specifications
Advice
Operation
Safety

Operation
The XDS system can detect and correct this
effect via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver's
desired trajectory is much more precise,
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected.
Brake servo The brake servo increases the pressure you
apply to the brake pedal. It works
only when
the engine is running .
If the brake servo is not functioning, e.g. due
to a malfunction, or if the vehicle is being
towed, you will have to press the brake pedal
considerably harder to make up for the lack
of servo assistance. WARNING
The braking distance can also be affected by
external factors.
● Never let the vehicle coast with the engine
switched off. Failure to follow this instruction
could result in an accident. The braking dis-
tance is increased considerably when the
brake servo is not active.
● If the brake servo is not working, for exam-
ple when the vehicle is being towed, you will have to press the brake pedal considerably
harder than normal.
Start-Stop System*
