equipped with the adaptive cruise control* ⇒page 134.
Note
A number of functions are monitored by the auto-check control
⇒page 21. If a malfunction should occur, this will be shown by the
display in the instrument cluster either with a red symbol (priority 1
– serious malfunction) or a yellow symbol (priority 2 – other
malfunction or item requiring attention).Applies to vehicles: with Audi drive selectDynamic steering

If the warning lamp
 lights up when you switch on the ignition and
goes out when the engine has started, the dynamic steering is acti-
vated.
If the warning lamp  stays on after the engine has started, this
indicates a malfunction in the system. You can continue driving
carefully at reduced speed to the next qualified workshop, however
the steering may feel heavier and its response may be more sensi-
tive than usual. In addition, it is possible that the steering wheel will
be off centre when driving in a straight line.
WARNING
Have the system malfunction in the dynamic steering repaired by
a qualified workshop as soon as possible – risk of accident.
Note
•
If the warning lamp
 flashes, this indicates that the dynamic
steering is being initialised. The message “Dynamic steering: Initial-
ising” ⇒page 36 will appear in the driver information system
display.
•

Driver information systemIntroductionGeneral notes
The driver information system in the instrument cluster
shows you the status of various on-board systems at a
glance.The display for the driver information system is in the centre of the
instrument cluster.
The system runs a check on certain components and functions
when the ignition is switched on and while the vehicle is moving. It
gives an audible warning if a fault should occur or if servicing is
required, and a red or yellow warning symbol (in some cases with a
corresponding driver message) appears in the dashboard display.
The system will also display information for the radio and CD player
and (if fitted) the route guidance directions from the navigation
system*. For further information on these systems, please refer to
the sound system or MMI* Operating Manual.
On some models the display of information shown in the instru-
ment cluster differs from the illustrations used here.
The driver information system includes the following functions:
Note
If a fault should occur, the display will show a red or yellow warning
symbol. A red warning symbol indicates a serious malfunction
⇒page 31. A yellow warning symbol indicates a less serious
malfunction, or other item requiring attention ⇒page 35.

Driver information system 22CD and radio displayIf no priority 1 or 2 faults have been detected by the auto-check
control, the name or frequency of the current radio station and the
selected waveband will appear the upper part of the display.
When a CD is playing, the display will show the current title. If the
vehicle is equipped with a CD changer* the display will also show
the number of the CD being played (CD1 to CD6).Outside temperature display
The outside temperature is shown when the display is
activated.
At temperatures below +5°C a snowflake symbol appears next to the
temperature display. This is to warn the driver to take extra care
when there is a risk of ice on the road.
When the vehicle is stationary or travelling at very low speeds, the
temperature displayed may be slightly higher than the actual
outside temperature as a result of the heat radiated from the
engine.
The temperature units can be set to °F or °C on the sound system or
MMI* system. The outside temperature is automatically displayed in
the units you have selected. Please refer to the sound system or
MMI* Operating Manual for further details.
WARNING
Do not rely on the outside temperature display as an ice warning.
Please bear in mind that there may be patches of ice on the roads
even at outside temperatures around +5°C.Applies to vehicles: with manual gearbox and gear-change indicatorGear-change indicator
This additional indicator function can help to save fuel.

Driver information system 30•
Speed warning - to set the speed above which a warning signal
will sound.
Speed limit warning 2 can be adjusted in increments of 10 km/h
between 30 and 240 km/h.
Auto-check controlIntroductionThe auto-check control checks important components and vehicle
systems. These background checks are run constantly, as long as
the ignition is switched on.
A message is displayed in the instrument cluster if a fault should
occur or if any maintenance or repairs are urgently required. This is
accompanied by an audible warning signal. Depending on the
priority of the fault, a red or yellow warning symbol lights up in the
display.
The red symbols indicate a serious malfunction, whereas the yellow
ones represent other malfunctions or items requiring attention.
Additional messages to assist the driver may be shown with the red
or yellow symbols.
Automatic gearbox* function test
The auto-check control automatically checks the vehicle systems
when the ignition is switched on. If the selector lever is in position
P or N, the following instruction will appear:
When stationary apply footbrake while selecting gear
When a gear (R, D etc.) is selected, this message disappears and the
auto-check control function is displayed.
The driver message will disappear 30 seconds after switching on
the ignition or earlier, if there are other driver messages or malfunc-
tions.If one or more faults are detected, the driver information message
(as above) will disappear about 15 seconds after the engine has
been started and the appropriate fault symbol(s) will appear in the
display. The warning display will be accompanied by the corre-
sponding warning chime.
Applies to vehicles: with speed warning functionDriver messages
Additional messages to assist the driver are displayed
together with the warning symbols in the instrument
cluster.For example, the following driver message will appear if the selector
lever for the automatic gearbox* is not in position P when you
switch off the engine:
Shift to P, otherwise vehicle can roll away. Doors do not lock if
lever is not in P.
The ignition key can only be withdrawn when the selector lever is in
this position. Similar messages will be displayed if other functions
of this kind cannot be carried out.
Driver messages and red symbols
If a red warning symbol appears in the display, it will automatically
be accompanied by the corresponding driver message.

If battery power drops to a level at which you may encounter prob-
lems when starting the engine, the display will show the symbol

and the driver message Low battery charge: Battery will be charged
while driving.
Please bear in mind that the starting ability of the engine may be
impaired while this message is shown.
Message comes on and goes out again
If the message appears in the display after the ignition is switched
on or while driving, and goes out again after a period of time, the
battery has been charged up again sufficiently while the vehicle was
being driven.
Message comes on and does not go out
If the message appears in the display after the ignition is switched
on or while driving, and does not go out again, the battery is not
being maintained at the proper power level. Starting reliability may
be impaired. You should have the battery checked by a qualified
workshop as soon as possible.

and have the oil level sensor checked. Until then it is advisable to
check the oil level every time you fill up with fuel ⇒page 258.
Applies to vehicles: with diesel engine and diesel particulate filterDiesel particulate filter obstructed


Particle filter. See Owner's Manual
When the symbol

lights up you can assist the self-cleaning func-
tion of the filter by driving accordingly. You should drive at a speed
of at least 60 km/h (engine speed about 2,000 rpm) for about
15 minutes in 4th or 5th gear, or with the selector lever in position S
on vehicles with automatic gearbox*. As a result of the increase in
temperature the soot in the filter will be burned off. The symbol will
disappear once the cleaning process has been completed success-
fully.
If the symbol

does not go out, please contact a qualified work-
shop and have the fault rectified.
For further information on the diesel particulate filter ⇒page 229.
WARNING
It is essential that you adjust your speed to suit the weather, road,
terrain and traffic conditions. The recommended driving speed
must never lead to the driver disregarding the traffic regulations.

Doors and windows 48
Locking the vehicle
– Move the selector lever to position P (automatic
gearbox), otherwise it will not be possible to lock the
vehicle.
– Touch the sensor on the door handle once to lock the
vehicle ⇒.
– Touch the sensor a second time within 2 seconds to lock
the vehicle without activating the deadlock mechanism.The vehicle can be locked and unlocked from any of the doors. The
driver's door will always be unlocked as well when the passenger's
door is unlocked. The remote control key has to be within a range of
about 1.5 metres of the relevant door or the boot lid. It does not
matter where you carry the key, for instance whether it is in your
jacket pocket or in a briefcase.
The unlocking function may be affected if the sensor area on the
door handle is touched while the vehicle is being unlocked.
The locking function may be affected if you grasp the door handle
while the vehicle is being locked.
Once the doors have been locked, they cannot be opened again
immediately. This will enable you to check that the doors are prop-
erly closed.
The system will either unlock all the doors or one door only,
depending on the settings you have chosen on the sound system or
MMI* ⇒page 50.
WARNING
Do not leave anyone (especially children) in the car if it is locked
from the outside and the deadlock mechanism is activated: the
doors and windows cannot then be opened from the inside.
Locked doors could delay assistance in an emergency, potentially
putting lives at risk.
Note
Please note the following points if the vehicle is left parked for long
periods:•
To save electrical power, the proximity sensors are switched off
after a few days. You will then need to pull the door handle once to
unlock the vehicle, and a second time to open it.
•
To prevent the battery from becoming discharged and thus
maintain the vehicle's starting ability for as long as possible, the
power management system will gradually switch off convenience
functions that are not required. In this case you may not be able to
unlock the vehicle with this convenience function.
Locking and unlocking the vehicle using the key
If the central locking system should fail to work, you can
still lock and unlock the driver's door by turning the emer-
gency key or spare key in the lock.Unlocking
– Turn the key to position ⇒fig. 40 to unlock the
vehicle.
