Electronic Stability Control (ESC)* /
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. 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 whilst driving when the ASR/ESC is activated.
● It will light up continuously if there is a fault in the ESC.
● As the ESC operates in conjunction with the ABS, it will also light up if a
fault should occur in the ABS.
If the ESC control lamp lights up and stays on after the engine is started,
this may mean that the control system has temporarily switched off the ESC.
In this case the ESC can be reactivated by switching the ignition off and
then on again. If the control 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 is disconnected when pressing the switch.Differential lock fault (EDL)*The EDL operates along with the ABS in vehicles equipped
with the Electronic Stability Control (ESC)*
A malfunction in the EDL is indicated by the ABS control 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)* /

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 is working if the vehicle is moving.
If the system is deactivated or if it has any fault, the warning lamp will re-
main lit. The warning lamp will also light up if a fault should occur in the
ABS because the ASR operates in conjunction with the ABS. For further in-
formation, see ⇒ page 187, Brakes
The lamp provides information about the disconnection status of the
system:
● It stays lit when the ASR is disconnected when pressing the ASR OFF
switch.
By pressing it again, the ASR 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. 134. 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 a Technical Service. The Technical Serv-
ice will help you to decide if special specific modifications 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)*
The ESC helps make driving safer in extreme driving condi-
tions.
Fig. 135 Detailed view of
the centre console: ESC
switch.
The Electronic Stability Control (ESC) contains the electronic differential lock
(EDL) and the traction control system (ASR). The ESC works together with
the ABS. Both control lamps will light up if the ESC or ABS systems are faul-
ty.
The ESC system is started automatically when the engine is started.
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.

Driving
Changing gear with the selector lever
– Put the lever in position D and press towards the right to enter
the tiptronic gate ⇒ Fig. 145.
– Press the gear lever forwards +
⇒ Fig. 145 to select a higher
gear.
– Press the gear lever back –
⇒ Fig. 145 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. 146.
– Press the left paddle –
towards the steering wheel to change
down ⇒ Fig. 146.
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. 146 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.
Kick-down 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 kick-down features on slippery
road surfaces. With a fast acceleration, the vehicle could lose traction
and skid.
● You should use the kick-down 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 and traction control systems
M-ABS (ABS and ASR) 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 239.
● If the running gear or brake system is modified, the effectiveness of
the ABS could be severely limited.
Drive wheel traction control system (ASR)
The traction control system prevents the driven 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 system 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 also stop working.
The ASR helps the car to start moving, accelerate and climb a gradient in
slippery conditions, where this may otherwise be difficult or even impossi-
ble.
189
Intelligent technology
The ASR automatically switches on when the engine is started. If necessary,
it may be turned on or off 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 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 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 situation. 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, running gear or to the combination of wheels and tyres) may
affect the operation of the ABS and ASR. 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 sensors and signals, the XDS system is able to detect and
correct this effect.
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 the ASR traction control is disconnected.
Electronic Stability Control (ESC)*
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) includes the ABS, EDL, ASR and Steer-
ing manoeuvre recommendation systems.
Safety FirstOperating InstructionsPractical TipsTechnical Specifications
190Intelligent technology
Electronic Stability Control (ESC*)
The ESC reduces the risk of skidding by braking the wheels individually.
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. When irregularities occur, for exam-
ple, if the vehicle begins to skid, the ESC brakes the appropriate wheel au-
tomatically.
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. This function
aids the driver to better stabilize the vehicle in a critical situation. For exam-
ple, 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 recognises the situation and assists the driver with a counter steer-
ing 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 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 situation. 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 engine power when this is not desired.
● Any modifications made to the vehicle (for example, to the engine,
brake system, running gear or to the combination of wheels and tyres) may
affect the operation of the ABS, EDL, ESC and ASR.
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 driven 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 217.
Drive wheel traction control system (ASR)
The traction control system prevents the driven 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 244.
