Electronic Stability Control ESC (ESP) * /
There are two control lamps for the electronic stability con-
trol. The lamp provides information concerning the func-
tion and the provides information on the disconnection
status
Both lamps come on together when the ignition is switched on and should
go out after approx. 2 seconds, which is how long the function check lasts.
This programme includes the ABS, EDL and ASR (TCS). This also includes
the brake assist system (BAS), automatic cleaning of the brake discs and
the trailer stability programme (TSP).
The warning lamp has the following functions: ● It flashes when the ASR (TCS)/ESC (ESP) is activated when driving.
● It will light up continuously if there is a malfunction in the ESC (ESP).
● The ESC (ESP) lamp will also come on if a fault should occur in the ABS
because the ESC (ESP) operates in conjunction with the ABS.
If the ESP warning lamp lights up and stays on after the engine is started,
this may mean that the control system has temporarily switched off the ESP.
In this case the ESC (ESP) can be reactivated by switching the ignition off
and then on again. If the warning lamp goes out, this means the system is
fully functional.
The lamp provides information about the disconnection status of the
system:
● It stays lit when the ASR (TCS) is disconnected after pressing the
switch. Differential lock fault (EDL)*EDL operates along with the ABS in vehicles equipped with
the Electronic Stability Control ESC* (ESP)
A malfunction in the EDL is indicated by the ABS warning lamp . Take the
vehicle to a specialised workshop as soon as possible. For further informa-
tion on the EDL see ⇒ page 190, Electronic differential lock (EDL)*.
Traction control system ASR (TCS)* /
The traction control system prevents the driven wheels from
spinning when the vehicle is accelerating
There are two warning lamps for the traction control system: and . Both
lamps come on together when the ignition is switched on and should go out
after approx. 2 seconds, which is how long the function check lasts.
The lamp has the following function:
● It flashes when the ASR (TCS) is activated while driving.
If the system is deactivated or if it has any fault, the warning lamp will re-
main lit. The ASR (TCS) lamp will also come on if a fault should occur in the
ABS because the ASR (TCS) operates in conjunction with the ABS. For fur-
ther information, see ⇒ page 187, Brakes
The lamp provides information about the disconnection status of the
system:
● It stays lit when the ASR (TCS) is disconnected after pressing the OFF
switch.
By pressing again, the ASR (TCS) function is reactivated and the warning
lamp switched off.

Driving
WARNING (Continued)
● Adjust the driver seat or steering wheel so that there is a distance of
at least 25 cm between the steering wheel and your chest ⇒ fig. 135. If
you fail to observe the minimum distance, the airbag will not protect you.
Risk of fatal injury.
● If your physical constitution does not allow you to maintain the mini-
mum distance of 25 cm, contact an Authorised Service Centre. The Au-
thorised Service Centre will help you to decide if special specific modifi-
cations are necessary.
● If you adjust the steering wheel so that it points towards your face,
the driver airbag will not protect you properly in the event of an accident.
Make sure that the steering wheel points towards your chest.
● When driving, always hold the steering wheel with both hands on the
outside of the ring at the 9 o'clock and 3 o'clock positions. Never hold
the steering wheel at the 12 o'clock position, or in any other manner
(e.g. in the centre of the steering wheel, or on the inside of the rim). In
such cases, if the airbag is triggered, you may sustain injuries to the
arms, hands and head.
Safety
Electronic Stability Control ESC* (ESP)
The ESC (ESP) helps to make driving safer in certain critical
handling situations.
Fig. 136 Detailed view of
the centre console: ESC
(ESP) button
The Electronic Stability Control ESC (ESP) contains the electronic differential
lock (EDL) and the traction control system ASR (TCS). The ESC (ESP) function
works together with the ABS. Both warning lamps will light up if the ESC
(ESP) or ABS systems are faulty.
The ESC (ESP) is activated automatically when the engine is started.
The ESC (ESP) is always active, and cannot be deactivated. With the ESC
(ESP) switch it is only possible to deactivate the ASR (TCS).
The ASR (TCS) can be deactivated in those cases where wheel sliding is de-
sirable.

Driving
Changing gear with the selector lever
– Put the lever in position D and press towards the right to enter
the tiptronic gate ⇒ fig. 146.
– Press the gear lever forwards +
⇒ fig. 146 to select a higher
gear.
– Press the gear lever back –
⇒ fig. 146 to select a lower gear.
Changing gear with the steering wheel levers
– Press the right paddle lever +
(+OFF) towards the steering
wheel to change up ⇒ fig. 147.
– Press the left paddle –
towards the steering wheel to change
down ⇒ fig. 147.
Using the paddle levers on the steering wheel, you can access manual driv-
ing mode regardless of the pre-selected driving mode.
General information about driving in tiptronic mode
When accelerating, the automatic gearbox / DSG automatic gearbox goes
into a higher gear a little before the engine reaches its maximum permitted
revolutions.
If a lower gear is selected, the automatic gearbox / DSG automatic gearbox
will only change down when the engine cannot go over its maximum permit-
ted revolutions.
If tiptronic is selected whilst the vehicle is in motion and the automatic
gearbox / DSG automatic gearbox is in third gear and selector lever position
D, tiptronic mode will then also be in third gear.
Changing gears in the normal or sport programme using the steering wheel
paddle levers
If the paddle levers ⇒ fig. 147 are used in the normal or sport programme,
the system switches temporarily to tiptronic mode. To exit tiptronic mode again, press the right paddle lever
+ OFF
towards the steering wheel for ap-
proximately one second. You will also leave tiptronic mode if the paddle lev-
ers are not moved for a certain time.
Note
● The gearbox controls on the steering wheel can operate with the selector
lever in any position and with the vehicle in motion.
Kickdown feature
This feature allows maximum acceleration. If you press the accelerator down thoroughly, the gearbox automatically
changes down, depending on speed and engine speed, into a lower gear to
take full advantage of give the vehicle maximum acceleration.
The gearbox does not change gear until the engine reaches the maximum
determined engine speed for the gear.
WARNING
You could lose control of the vehicle if you accelerate on slippery road
surfaces. Risk of serious injury.
● Be particularly careful when using the kickdown features on slippery
road surfaces. With a fast acceleration, the vehicle could lose traction
and skid.
● You should use the kickdown feature only when traffic and weather
conditions allow it to be used safely.
Safety FirstOperating InstructionsPractical TipsTechnical Specifications
188Intelligent technology
WARNING
● The risk of accident is higher if you drive too fast, if you do not keep
your distance to the vehicle in front, and when the road surface is slip-
pery or wet. The increased accident risk cannot be reduced by the brake
assist system.
● The brake assist system cannot defy the laws of physics. Slippery
and wet roads are dangerous even with the brake assist system! There-
fore, 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 and traction control
M-ABS (ABS and ASR (TCS))
Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking dur-
ing braking. The anti-lock brake system (ABS) is an important part of the vehicle's active
safety system.
How the ABS works
If one of the wheels is turns too slowly in relation to the road speed, and is
close to locking, the system will reduce the braking pressure for 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 de-
pressed so the ABS can regulate the brake application. Do not “pump”. If you brake hard on a slippery road surface, the best possible control is re-
tained as the wheels do not lock.
However, ABS will not necessarily guarantee shorter braking distances in
all
conditions. The braking distance could even be longer if you brake on gravel
or on fresh snow covering 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 features tempt you into taking any risks when driving.
● The effectiveness of ABS is also determined by the tyres fitted
⇒ page 236.
● If the running gear or brakes are modified, the effectiveness of the
ABS could be severely limited.
Traction control system ASR (TCS)
The traction control system prevents the drive wheels from
spinning when the vehicle is accelerating. Description and operation of the traction control system during
acceleration ASR (TCS)
ASR (TCS) reduces engine power to help prevent the drive wheels of front-
wheel drive vehicles losing traction during acceleration. The system works
in the entire speed range in conjunction with ABS. If a malfunction should
occur in the ABS, the ASR (TCS) will also stop working.
The ASR (TCS) helps the vehicle to start moving, accelerate and climb a gra-
dient in slippery conditions where this may otherwise be difficult or even
impossible.
189
Intelligent technology
The ASR (TCS) is connected automatically when the engine starts. If neces-
sary, it may be turned on or off pushing the button on the centre console.
When the ASR (TCS) is disconnected, the warning lamp
OFF
lights up. The
TCS should normally be left on. Only in exceptional circumstances, when the
slipping of the wheels is required, should it be disconnected, for example
● With compact temporary spare wheel.
● When using the snow chains.
● When driving in deep snow or on loose surfaces
● When the vehicle is bogged-down, to free it by rocking.
The TCS should be switched on again as soon as possible.
WARNING
● Remember that the ASR (TCS) cannot 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 situation. Do not let the extra safety afforded by ASR (TCS)
tempt you into taking any risks when driving.
CAUTION
● To ensure that the ASR (TCS) functions 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 engine power when this is not desired.
● Modifications to the vehicle (e.g. to the engine, the brake system, run-
ning gear or any components affecting the wheels and tyres) could affect
the efficiency of the ABS and ASR (TCS). XDS*
Driveshaft differential
When taking a bend, the driveshaft differential mechanism allows the outer
wheel to turn at a higher speed than the inner wheel. In this way, the wheel
that is turning faster (outer 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 under-
steer or “lengthening” of the trajectory.
By using the ESC (ESP) sensors and signals, the XDS system is able to de-
tect and correct this effect.
Through the ESC (ESP), the XDS brakes the inner wheel, thereby counteract-
ing the excess drive torque in this wheel. This means that the driver's de-
sired trajectory is much more precise,
The XDS system operates in combination with the ESC (ESP) and is always
active, even when the traction control ASR (TCS) is disconnected.
Electronic Stability Control ESC (ESP) *
General notes
The Electronic Stability Control increases the vehicle's stabil-
ity on the road. The Electronic Stability Control helps reduce the danger of skidding.
The Electronic Stability Control ESC (ESP) includes the ABS, EDL, ASR (TCS)
and Steering manoeuvre recommendations.
Safety FirstOperating InstructionsPractical TipsTechnical Specifications
190Intelligent technology
Electronic Stability Control ESC* (ESP)
The ESC (ESP) reduces the danger of skidding by braking the wheels indi-
vidually.
The system uses the steering wheel angle and road speed to calculate the
changes of direction desired by the driver, and constantly compares them
with the actual behaviour of the vehicle. If the desired course is not being
maintained (for instance, if the vehicle is starting to skid), then the ESC
(ESP) compensates automatically by braking the appropriate wheel.
The forces acting on the braked wheel bring the vehicle back to a stable
condition. If the vehicle tends to oversteer, the system will act on the front
wheel on the outside of the turn.
Steering manoeuvre recommendations
This is a complementary safety function included in the ESC (ESP). This
function aids the driver to better stabilize the vehicle in a critical situation.
For example, in case of sudden braking surface with varied adherence, the
vehicle will tend to destabilise its trajectory to the right or to the left. In this
case the ESC (ESP) recognises the situation and helps the driver with a
counter steering manoeuvre from the power steering.
This function simply provides the driver with a recommended manoeuvre in
critical situations.
The vehicle does not steer itself with this function, the driver has full control
of the vehicle at all times.
WARNING
● Remember that ESC (ESP) cannot 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 situation. Do not let the extra safety afforded by ESC (ESP)
tempt you into taking any risks when driving.
CAUTION
● To ensure that the ESC (ESP) functions 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 engine power when this is not desired.
● Modifications to the vehicle (e.g. to the engine, the brake system, run-
ning gear or any components affecting the wheels and tyres) could affect
the efficiency of the ABS, EDL, ESC (ESP) and ASR (TCS).
Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking during braking
⇒ page 188.
Electronic differential lock (EDL)*
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.
EDL helps the vehicle to start moving, accelerate and climb a gradient in
slippery conditions where this may otherwise be difficult or even impossi-
ble.
The system will control the revolutions of the drive wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒ page 82.
At speeds of up to approximately 80 km/h, it is able to balance out differen-
ces in the speed of the driven wheels of approximately 100 rpm caused by a
slippery road surface on one side of the vehicle. It does this by braking the
wheel which has lost traction and distributing more driving force to the oth-
er driven wheel via the differential.
191
Intelligent technology
To prevent the disc brake of the braking wheel from overheating, the EDL
cuts out automatically if subjected to excessive loads. The vehicle will con-
tinue to function normally without EDL. For this reason, the driver is not in-
formed 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 accelerator 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 into tak-
ing any risks when driving, this can cause accidents.
CAUTION
Modifications to the vehicle (e.g. to the engine, the brake system, running
gear or any components affecting the wheels and tyres) could affect the effi-
ciency of the EDL ⇒ page 214.
Traction control system ASR (TCS)
The traction control system prevents the drive wheels from spinning when
the vehicle is accelerating ⇒ page 188. All-wheel drive*
On all-wheel drive models, the engine power is distributed
to all four wheels
General notes
The all-wheel drive system operates completely automatically. The propul-
sion force is distributed among the four wheels and adapted to the driving
style and the road conditions.
The all-wheel drive is specially designed to complement the superior engine
power. This combination gives the vehicle exceptional handling and per-
formance capabilities, both on normal roads and in more difficult condi-
tions, such as snow and ice.
Winter tyres
Thanks to its all-wheel drive, your vehicle will have plenty of traction in win-
ter conditions, even with the standard tyres. Nevertheless, we still recom-
mend that winter tyres or all-season tyres should be fitted on all four wheels
when winter road conditions are expected, mainly because this will give a
better braking response.
Snow chains
On roads where snow chains are mandatory, this also applies to cars with
all-wheel drive.
Changing tyres
On vehicles with all-wheel drive, all four tyres must have the same rolling
circumference ⇒ page 241.
