Instruments and warning/indicator lamps
16Additional warning and indicator lamps are displayed on vehicles
equipped with the adap tive 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 starte d, 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 addi tion, 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.
•
The stabilisation functions of the dynamic steering ⇒page 222
are not available in the event of a system malfunction.

This warning lamp monitors the engine management
system on petrol engines.The
warning lamp (Electronic Power Control) lights up when the
ignition is switched on to show that the lamp is working properly.Note
If the warning lamp lights up while the vehicle is moving, this indi-
cates a fault in the engine management system. The engine should
be serviced by a qualified workshop without delay.Applies to vehicles: with diesel engineGlow plug system
The indicator lamp lights up to show that the glow plugs
are preheating.Your vehicle is equipped with an automatic glow plug system.
The indicator lamp
lights up while the glow plugs are preheating.

Note
•
If the glow plug indicator lamp should start flashing while the
vehicle is moving, this indicates a fault in the engine management
system. The engine should be serviced without delay.
•
If the indicator lamp fails to light up when the ignition is
switched on, this can mean that the glow plug system is defective.
The engine should be serviced.
Electronic stabilisation program (ESP)
This warning lamp monitors the electronic stabilisation
program.The warning lamp
has the following functions:
•
It flashes when the ESP or tracti on control system (ASR) inter-
venes while the vehicle is in motion.
•
The warning lamp will light up continuously if the ESP or the
traction control system (ASR) has been switched off using the ESP
OFF button ⇒page 222 .
•
It lights up when the ignition is switched on and should go out
again after about 2 seconds. This signals that the lamp is working
properly.
•
It will light up continuously if there is a malfunction in the ESP.
•
It will also come on if a fault should occur in the ABS because the
ESP operates in conjunction with the ABS.
If the battery has been disconnected , if the battery voltage is very
low, or if the engine has been started from an outside power source,
the ESP system will perform an initialisation of the various on-board
sensors while you drive the first few metres. The warning lamp will
light up during this period. It will go out when the initialisation has
been completed.
If the warning lamp lights up an d stays on after the engine is
started, this may mean that the control system has temporarily
switched off the ESP. In this case the 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.
For further information on the ESP
⇒page 222 .
Airbag system
This warning lamp monitors the airbag and seat belt
tensioner system.The warning lamp
should light up for a few seconds when the
ignition is switched on.
If the warning lamp does not go out, or if it lights up, flashes or
flickers when the vehicle is moving, this indicates a malfunction in
the system. This is also the case if the warning lamp does not light
up when the ignition is switched on.
WARNING
If a malfunction should occur, have the system checked immedi-
ately by a qualified workshop. If th is is neglected, there is a risk
that the airbag system and/or belt tensioners may not be acti-
vated in an accident.Tyre pressure monitoring
The tyre pressure should be corrected as soon as possible
if it is too low.If the
symbol flashes for about a minute and then remains lit after
you switch on the ignition, there is a fault in the system. Please
contact the nearest qualified workshop as soon as possible.
For more detailed information on the tyre pressure monitoring
system, please refer to ⇒page 39 .

in the instrument cluster lights up when the
cruise control system is operating.
Anti-lock brake system (ABS)
The warning lamp monitors the ABS and the electronic
differential lock (EDL).The warning lamp
lights up for a few seconds when the ignition
is switched on and while the engine is being started. The lamp goes
out again once the system has run through an automatic test
sequence.
There is a fault in the ABS if:
•
the warning lamp
does not light up when the ignition is
switched on,
•
the warning lamp does not go out again after a few seconds,
•
the warning lamp lights up when the vehicle is moving.
The vehicle can still be braked in the normal way (except that the
ABS control function is out of action). Please take the vehicle to a
qualified workshop as soon as po ssible. For further information on
the ABS ⇒ page 222.
If a fault occurs in the ABS, the ESP warning lamp will also light up.
Fault in the main brake system
If the ABS warning lamp
lights up together with the brake
warning lamp
⇒ page 32 , this indicates a fault in the ABS func-
tion, and possibly a malfunction in the main brake system as well
⇒ .
If there is a malfunction in the brake system the symbol
will light
up in the instrument cluster. Please refer to ⇒page 32 . Fault on the electronic differential lock (EDL)
The EDL works in conjunction with the ABS. If a malfunction should
occur in the EDL, this is indicated by the ABS 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
should light up together with the
ABS warning lamp
, stop the vehicle imm ediately and check the
brake fluid level in the reservoir. If the fluid level has dropped
below the "MIN" mark you must no t drive on - otherwise there may
be an increased acciden t risk. You should obtain professional
assistance.
•
If the brake fluid level is OK, the fault in the brake system may
have been caused by a failure of the ABS control function. As a
result the rear wheels can lock relatively easily when braking. This
could cause the tail of the vehicle to skid sideways. Drive carefully
to the nearest qualified workshop and have the fault rectified.
Applies to vehicles: with Audi hold assistAudi hold assist
This warning lamp monitors the Audi hold assist function.Audi hold assist helps the driver to keep the vehicle stationary while
the engine is running, for instance on steep gradients, at traffic
lights or in stop-and-go traffic. When the Audi hold assist function
is on, you don't have to keep your foot on the brake to prevent the
vehicle from accidentally rolling away. Once it detects that the
vehicle is stopped, Audi hold assist keeps the vehicle stationary. The
green symbol
in the instrument cluster indicates that the func-
tion is activated. You can now take your foot off the brake pedal.

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

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

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.

braking force of the parking brake is only released when there is
enough power at the wheels to make the vehicle move in the desired
direction.
Note
For safety reasons the parking brake will only release automatically
if the driver's seat belt
is engaged in its buckle.Driving away when towing a trailer
Please note the following po ints to prevent the vehicle
from rolling back unintentionally on a gradient.– Pull and hold the parking brake switch and press the
accelerator. The parking brake will remain engaged and
prevent any tendency to roll back down the slope.
– You can release the parking brake switch as soon as the engine is delivering enough power to the wheels.Depending on the weight of the vehicle and trailer and the steep-
ness of the slope, there may be a tendency to roll back downhill
when driving away from a standstill. You can prevent this by pulling
out the parking brake switch as you press the accelerator (in the
same way as with a conventional handbrake).Emergency braking function
This feature enables you to stop the vehicle if the main
brake system should fail or if the pedal is obstructed.– Pull out and hold the parkin g brake switch to stop the
vehicle with the parking brake in an emergency.
– The brakes will be released immediately if you release the switch or press down the accelerator.
If you pull out and hold the park ing brake switch at a road speed
above about 8 km/h, this will initiate an emergency brake applica-
tion. The brakes are then applied hy draulically at all four wheels.
The effect is the same as an emergency stop (full brake application)
⇒
To prevent the emergency braking function from being used acci-
dentally, a warning buzzer sounds when the switch is operated. The
brakes are released immediately when you release the switch or
press down the accelerator.
WARNING
You should only use the emergency braking function in a real
emergency, for example if the brake system should fail or if the
brake pedal is obstructed. If you use the emergency braking func-
tion by activating the parking brak e switch, the effect is similar to
a full brake application (emergenc y stop). Please remember that
the ESP (with its combined ABS, EDL and traction control func-
tions) is still subject to certain physical limits. In a corner or in bad
road or weather conditions an emergency stop can cause the
vehicle to skid or lose steering control.Driver messages in the instrument cluster displayCaution: Vehicle parked too steep
This message can appear when you apply the parking brake if the
car is parked on a gradient steeper than about 30%.
In this case the parking brake may not be strong enough to prevent
the vehicle from rolling back accidentally.
Please release parking brake
However, please remember that, for safety reasons, the parking
brake will only release automatically if the driver's seat belt is
buckled.
