Instruments and warning/indicator lamps
20When the vehicle has been stationary for an extended period, Audi
hold assist will automatically appl y the parking brake. In this case,
the green symbol
 will change to red
.
Electro-mechanical parking brake

This warning lamp monitors the electro-mechanical
parking brake.The warning lamp
 lights up when the parking brake is applied
with the ignition on. After the ig nition has been switched off the
lamp will stay on for about 30 seconds. The warning lamp will light
up for about 30 seconds if the parking brake is applied with the igni-
tion switched off.
The warning lamp should go out when the parking brake is released.
If the warning lamp flashes continuously after the parking brake has
been applied , the brake may not be strong enough to hold the
vehicle on a slope. This may be due to the brakes overheating.
Please note the following points:
•
If the gradient is too steep to park the vehicle safely, the display
will show the message Caution: Vehicle parked too steep .
•
In the event of a fault in the parking brake system the symbol

will also appear in the instrument cluster display together with the
message Parking brake! You should have the fault corrected by a
qualified workshop without delay.
Brake system

The warning lamp flashes if the brake fluid level is too low
or if there is a fault in the ABS system or the parking
brake.If the warning lamp
 flashes, there is a fault in the brake system.
The symbol
 in the instrument cluster display will flash at the same time. You can press the button to obtain a message
explaining the fault
⇒page 32 .
If a failure should occur in the ABS, the ABS warning lamp
 will
light up together with the brake warning lamp
 ⇒ .
WARNING
•
Before opening the bonnet and ch ecking the brake fluid level,
observe the warning information on ⇒page 255, “Working on
components in the engine compartment”.
•
If the brake warning lamp does not go out, or if it lights up
when driving, the brake fluid level in the reservoir is too low – this
may cause an increased accident risk. Stop the vehicle and do not
drive on. You should obtain professional assistance.
•
If the brake warning lamp lights up together with the ABS
warning lamp, this can mean that the control function of the ABS
is out of action. As a result the rear wheels can lock relatively
easily when braking. This could caus e the tail of the vehicle to skid
sideways. Drive carefully to the nearest qualified workshop and
have the fault rectified.

 Dynamic steering: system fault
This message and the
 symbol will appear if a fault develops in the
system while the vehicle is moving. You can continue driving care-
fully at reduced speed to the next qualified workshop, however the
steering may feel heavier and its response may be more sensitive than usual. In addition, it is possible that the steering wheel will be
off centre when driving in a straight line.
Dynamic steering: initialising
If this message appears and the warning lamp
 flashes in the
instrument cluster, this indicates that the dynamic steering is being
initialised. The steering wheel will move slightly after the engine is
started. The dynamic steering may be initialised if the steering
wheel was moved while the vehicle was stopped. The warning lamp
will go out when the initialisation has been completed.
WARNING
Have the system malfunction in the dynamic steering repaired by
a qualified workshop as soon as possible – risk of accident.
Note
The stabilisation functions of the dynamic steering ⇒page 222 are
not available in the event of a system malfunction.Applies to vehicles: with advanced keyKey not in vehicle

Driver information system
40The tyre pressure monitoring system makes use of the ABS sensors
to compare the rolling circumfe rence and the vibration of the
wheels. The display in the instrument cluster alerts the driver if
changes are detected on one or more wheels. If only one tyre is
affected, the display will indicate its position ⇒fig. 27.
Each time you change a tyre or the tyre pressures on your vehicle,
you must store the new tyre pressures via the sound system or
MMI* ⇒page 41 .
The rolling circumference and vibration can change if:•
The tyre pressure is too low
•
The tyre has suffered structural damage
•
The air pressure in one or more tyres was changed and the new
tyre pressures were not stored ⇒page 41, “Storing the tyre pres-
sures”
•
The wheels were changed and the new tyre pressures were not
stored ⇒page 41, “Storing the tyre pressures”
•
There is a greater load on the wheels of one axle (e.g. if you are
carrying more passengers or luggage)
•
The road surface under the left wheels is different to the road
surface under the right wheels for a long period
Warning lamp
 / TPMS Tyre pressure ! System malfunction
If the warning lamp  flashes for about a minute and then remains
lit after you switch on the ignition, there is a fault in the system. TPMS
(Tyre Pressure Monitoring System) Tyre pressure ! System
malfunction ⇒ page 40, fig. 28 will also be displayed in the instru-
ment cluster. Please contact the ne arest qualified workshop as soon
as possible.
WARNING
•
If the tyre pressure warning lamp appears in the instrument
cluster display, slow down i mmediately and avoid any severe
braking or steering manoeuvres. As soon as you can do so safely,
stop and check the tyres and the tyre pressures.
•
It is the driver's responsibility to ensure that the tyre pressures
are correct. For this reason yo u must check the tyre pressures
regularly.
•
Under certain conditi ons (e.g. driving at high speeds, on ice and
snow or on poor road surfaces) the tyre pressure warning lamp
may not light up immediately or not at all.
•
Please ask your Audi dealer or qualified workshop whether run
flat tyres can be used on your vehicle. Unauthorised use of these
tyres can invalidate the vehicle's type approval for use on public
roads. Furthermore, this could cause damage to your vehicle and
possibly also result in an accident.

Technical data
Audi lane assistAudi lane assistApplies to vehicles: with lane assistDescription
The lane assist system assist s the driver in keeping the
vehicle in the right lane.The system uses a camera to detect the markings of the lane you are
driving in. If the vehicle approaches one of the detected lane mark-
ings, the steering wheel vibrates to warn the driver that the vehicle
might be about to cross one of the markings. The lane assist system
is functional when it has detected lane markings on both sides of
the lane you are driving in. The green lamp
 in the instrument
cluster indicates that the function is activated and fully functional.
If you operate the turn signal before crossing one of the lane mark-
ings (while the lane assist system is functional), the system will
detect that the lane change is in tended and will not warn the driver.
As the system is designed for driving on motorways and other major
roads, it is only active above a speed of about 65 km/h.
WARNING
•
The lane assist system does not keep the vehicle in its lane. It
merely warns the driver when the vehicle is in danger of crossing
the markings of the lane. As the driver you are always responsible
for staying in your own lane.
•
The camera cannot det ect all lane markings. Therefore it is
possible that variations in the road surface or objects might be
detected as lane markings, which can lead to false warnings, or
warnings not being given.
•
The camera's view might be obst ructed, for example by vehi-
cles travelling in front, rain, snow, a lot of water on the road or adverse light. This can result in
the system not detecting the lane
markings correctly.
Applies to vehicles: with lane assistSwitching on and off– Press the button ⇒fig. 158 -arrow- to switch the system
on and off. The indicator lamp

in the instrument
cluster will light up or go out.

Messages in the instrument cluster display
Should the lane assist be deacti vated automatically, the indicator
lamp in the instrument cluster will go out and one of the following
messages will appear in the instrument cluster display:
Audi lane assist not available: currently no sensor vision
This message is displayed when the camera is no longer functional
after the system has continuously failed to detect the lane mark-
ings. This can have the following causes:
•
The outside of the camera window ⇒page 145, fig. 159 is dirty
or frosted. Please remove dirt or ice from this area of the wind-
screen.
•
The inside of the camera window is misted up. In this case,
please wait for the camera window to demist before switching on
the lane assist system again.
•
Due to the conditions (e.g. snow-covered road) the system has
not been able to detect the lane markings for a long period. Do not
switch the lane assist system on again before the lane markings are
discernible.
Audi lane assist currently not available
A temporary error is preventing the lane assist system from fully
functioning. Try switching on the lane assist system again later. Audi lane assist: system fault The system should be checked by an Audi dealership or other qual-
ified workshop.
Applies to vehicles: with lane assistSetting the warning time and steering vibration
You can change the lane assist settings on the sound
system or MMI* to suit
your individual preferences.– Select: Function selector button > Audi lane assist.Setting time of warning
early: In this setting, the driver wi ll be warned before a wheel
crosses a lane marking. The warning depends on the angle with
which the vehicle is approaching the lane marking. The larger the
angle with which you are driving towards the marking, the earlier
you will receive the warning, i.e. the distance between the vehicle
and the marking might still be still relatively long. If you are driving
toward the marking at a very narrow angle, you will receive the
warning later, i.e. shortly before one of the wheels touches the
marking.
adaptive : In this setting, the time of warning is adapted to the road
layout and the vehicle's speed. The warning will be received later
when you are driving through a bend, and earlier when you are

Automatic gearbox
166
WARNING
Please note that if the road sur face is slippery or wet, the kick-
down feature could ca use the driving wheels to spin, which could
result in skidding.Applies to vehicles: with multitronic® or tiptronicDynamic gear control program (DCP)
The automatic gearbox is controlled electronically.The vehicle is equipped with an electronically controlled gearbox.
The gear ratios are selected automatically according to preset gear-
shift programmes.
When you drive at moderate speeds the gearbox will select the most
economical shift programme. It will then change up early and delay
the downshifts to gi ve better fuel economy.
If you drive at higher speeds with heavy acceleration, if you open the
throttle quickly, or if you use the kick-down or the car's maximum
speed, the gearbox will automaticall y select the more “sporty” shift
programmes.
The gearbox is self-adapting, and continuously selects the most
suitable shift programme. At the same time, the driver can also
make the gearbox switch to a more "sporty" programme by pressing
the accelerator quickly. Depending on road speed, this makes the
gearbox shift down early into a lower gear ratio for more rapid accel-
eration (for instance to pass another vehicle), without having to
press the accelerator all the way down into the kick-down position.
After the gearbox has shifted back up it returns to the original
programme, depending on your style of driving.
Vehicles with multitronic® gear box: The gearbox continuously
adapts the gear ratios on uphill gradients. If the brake pedal is
pressed on a downhill gradient the gearbox automatically shifts to
a lower gear ratio. This increases the engine braking effect. Vehicles with tiptronic gearbox:
The gearbox adapts the gearshifts
for uphill and downhill gradients. This prevents the gearbox from
shifting up and down unnecessarily on uphill gradients.
Applies to vehicles: with multitronic® or tiptronicManual gear selection (tiptronic mode)
With the manual shift programme (tiptronic) the driver
can manually select pre-programmed gears.Switching over to the manual programme
– From position D, push the selector lever to the right. As soon as the automatic gearbox has changed over to this
programme, the display will show the selected gear.
