Technical data
•
Adaptive cruise control will not react when approaching a
stationary obstacle, e.g. the end of a traffic jam or a broken-down
vehicle, or if a vehicle should come towards you in the same lane.
•
Please make sure you do not unintentionally rest your foot on
the accelerator - this will override the adaptive cruise control
system which, as a result, will not automatically brake the vehicle.Note
•
For safety reasons, the speed setting will be deleted when the
ignition is switched off.
•
Switching on the adaptive cruise control automatically activates
the Electronic Stabilisation Program (ESP) and the traction control
system (ASR). These two systems cannot be deactivated while the
adaptive cruise control is switched on.
•
Damage caused by impacts (e.g. if the vehicle is damaged when
parking) can affect the radar sensor settings. This can cause the
system to malfunction or switch off completely.
•
The radar sensor is heated. However, in winter conditions, you
should make sure that the radar sensor is free of ice and snow
before you set off. If necessary, carefully clean the cover of the radar
sensor and the surrounding area ⇒page 128, fig. 136.
•
To make sure that the radar sensor is fully operative, do not
attach any objects (e.g. stickers, add-on parts or other accessories)
to the area surrounding the radar sensor. Do not paint the area
surrounding the radar sensor.
Applies to vehicles: with adaptive cruise control and manual gearboxVehicles with manual gearbox
The driver of a vehicle with a manual gearbox of course
has to change gears as appropriate, even when the adap-
tive cruise control is activated.The adaptive cruise control is available from the second to the sixth
gear (when driven in normal engine speed range).
When the adaptive cruise control is activated, the driver must press
the clutch pedal as normal in order to change gear. When changing
gear or pressing the clutch pedal (for up to 20 seconds), the adap-
tive cruise control will remain activated.
When changing gear, the driver does not have to accelerate after
engaging a gear as the engine torque will be coordinated by the
adaptive cruise control.
The following situations may lead to an automatic deactivation of
the adaptive cruise control :•
pressing the clutch pedal too long (longer than approx.
20 seconds)
•
incorrect changing of gears and/or use of the clutch pedalNote
•
The adaptive cruise control cannot be activated while changing
gears.

Automatic gearbox
162Automatic gearboxmultitronic
®, tiptronic (6-speed
gearbox)
Applies to vehicles: with multitronic® or tiptronicIntroductionApplies to vehicles with multitronic
® gearbox
The vehicle is equipped with an electronically controlled continu-
ously variable transmission (multitronic
®). Unlike conventional
automatics, the gear ratios are not shifted in fixed steps but contin-
uously variable. This gives smoother transmission and makes for
better fuel economy.
The gearbox selects the gear ratio and shifts up or down automati-
cally according to the gear change programmes stored in the
control unit ⇒page 166 .
If desired, you can also select the gears manually (tiptronic mode)
⇒ page 166 .
Please note that on ve hicles with a multitronic® gearbox, torque is
transmitted via a multi- plate clutch, and not via a torque converter
as on conventional automatics. This means that the car will not
“creep” as much as conventional automatics when the engine is
idling if you stop temporarily with the selector lever in position D, S
or R.
Applies to vehicles with tiptronic gearbox
The vehicle is equipped with an electronically controlled 6-speed
automatic gearbox. The gearbox changes up and down automati-
cally .
If desired, you can also select the gears manually (tiptronic mode)
⇒ page 166 .
Applies to vehicles: with multitronic® or tiptronicGeneral notes on using multitronic
®
The gears are changed automatically.Driving away from a standstill
– Press and hold the brake pedal.
– Press and hold the interlock button (the button in the
selector lever handle), move the selector lever to the
desired position, for instance D, and release the interlock
button.
– Wait for the gearbox to engage the gear (a slight move- ment can be felt).
– Release the brake and press the accelerator ⇒.
Stopping briefly
– Apply the foot brake to hold the vehicle when stationary (for instance at traffic lights).

Child safety211
Controls
Safety
Driving tips
General maintenance
Self-help
Technical data
•
If children lean forward or are otherwise out of position when
the car is moving, they are at greater risk of injury in an accident.
This is particularly the case if the child is travelling on the front
passenger's seat and the airbag system is triggered in an accident.
There is then a risk of serious or potentially fatal injury.
•
To ensure proper protection, it is important to wear the seat
belts in the co rrect position ⇒page 197, “How to wear seat belts
properly”. Always check that th e belt is properly positioned
according to the instru ctions provided by the manufacturer of the
child safety seat. Incorrectly worn seat belts can give rise to inju-
ries even in a minor collision.
•
Never install a rearward-facing child safety seat on the front
passenger's seat if the front pass enger's airbag has not been deac-
tivated ⇒page 211 .
•
Extra caution is advised if you ar e installing a child safety seat
using the same mounting bolts as the existing car seat belts. The
bolts must be screwed in all the way to the full depth of the
mounting holes and ti ghtened to a torque of 50 Nm. Failure to
observe this precaution could result in potentially fatal injury. We
recommend having the installation performed by a qualified
workshop.
Using a child safety seat on the front passenger's seat
Whenever possible, child safety seats should always be
installed on the rear seat.For safety reasons, we recommend that child safety seats should be
installed on the rear seats whenever possible. However, if you have
to use a child seat on the front passenger's seat when there is no
other alternative , it is most important to note the following warn-
ings:
WARNING
•
Do not use a rearward-facing child safety seat on the front
passenger's seat unless the fr ont passenger's airbag has been
deactivated. The child seat would be directly in the path of the
airbag as it inflates, and the child could sustain serious or fatal
injuries if the airbag were to be deployed.
•
However, if you have no alte rnative but to use a rearward-
facing child seat on the front passenger's seat, the front
passenger's airbag must be deac tivated beforehand by means of
the key-operated switch* ⇒page 208. Failure to observe this
precaution could result in serious or potentially fatal injury.
•
Make sure that the front passen ger's airbag is reactivated by
means of the key-operated switch* as soon as the child seat is no
longer needed on the front passenger's seat.
•
When using a child safety seat of the type which faces in the
direction of travel, the front pass enger's seat must be moved back
to the rearmost position.

Intelligent technology
222Intelligent technologyElectronic stabilisation program (ESP)DescriptionESP increases the car's stability. It reduces the tendency to skid and
improves the stability and roadhold ing of the vehicle. ESP detects
critical handling situations, such as understeer, oversteer and
wheelspin on the driven wheels. It stabilises the vehicle by braking
individual wheels or by reducing the engine torque. The warning
lamp
 in the instrument cluster starts flashing as soon as the ESP
intervenes.
The ESP incorporates the functions of the anti-lock brake system
(ABS), the traction control system (ASR), the electronic differential
lock (EDL) and the dynamic steering*.
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under braking until the
vehicle has reached a virtual standstill. You can continue to steer the
vehicle even when the brakes are on full. Keep your foot on the brake
pedal and do not pump the brakes. You will feel the brake pedal
pulsate while the anti-lock brake system is working.
Brake assist system
The brake assist system can speed up the braking process and
shorten the braking distance. It au tomatically boosts the braking
force if you press the brake pedal quickly in an emergency. On vehi-
cles with adaptive cruise control*, the brake assist system will build
up a small amount of pressure in the hydraulic brake system if it
senses that you are too close to the vehicle in front.
Traction control system (ASR)
In the event of wheelspin, the traction control system reduces the
engine torque to match the amount of grip available. This helps the
car to start moving, accelerate or climb a gradient. Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes the spinning wheel and
directs the power to the other driven wheel (or wheels on quattro*
versions). This function is active up to about 100 km/h.
To prevent the disc brake of the braked wheel from overheating, the
EDL cuts out automatically if subjected to excessive loads. The
vehicle can still be driven. The EDL will switch on again automati-
cally when the brake has cooled down.
Dynamic steering*
On vehicles with dynamic steering*, the ESP can also intervene in
the steering to stabilise the vehicle in critical situations.
WARNING
•
The grip provided by the ESP,
ABS, ASR, EDL and dynamic
steering* systems is still subject to the physical limits of adhesion.
Always bear this in mind, especia lly on wet or slippery roads. If
you notice the systems cutting in , you should reduce your speed
immediately to suit the road and traffic conditions. Do not let the
extra safety provided tempt you into taking any risks when driving
– this can cause accidents.
•
Please remember that the acciden t risk always increases if you
drive fast, especially in corners or on a slippery road, or if you
follow too close behind th e vehicle in front of you. Please bear in
mind that even ESP, ABS, brak e assist, EDL, ASR and dynamic
steering* cannot compensate for the increased accident risk.
•
When accelerating on a uniformly slippery surface (for instance
all four wheels on ice or snow), pr ess the accelerator gradually and
carefully. The driven wheels may ot herwise start to spin (in spite
of the integrated control systems), which would impair the car's
stability and could lead to an accident.
