Significant loss of air pressure l
The warning/indicator light appears in the event of a
significant loss of air pressure.
The 'warning/ indicator light illum inates when you switch on the
ign ition and must go out after the engine has started .
If the
I symbo l appears, pressure is too low in at least one tire.

Malfunction Indicator Lamp (MIL) ....;
The Malfunction Indicator Lamp (MIU is part of the On-Board Diag ­
nostic (OBD II) system. The symbol lights up when the ignition is
turned on and will turn off after the engine has started and has sett led at a constant id le speed. This indicates that the MIL is
work ing proper ly .
The warning light illuminates when there is a malfunction in the
engine electronic system. Contact your authorized Audi dealer and
have the malfunction corrected .
An improperly closed fuel filler cap may also cause the MIL light to
illuminate
~ page 305.
For more information ~ page 27. •
Safety belts 4i-
This warning/indicator light reminds you to put on your
safety belt.
The 4,_ warning/indicator light illuminates when the ignition is
switched on to remind the driver and any front passenger to put on
the safety belt. Additionally, an acoustic warning (gong) will also
sound. For more
Information~
page 211, "Safety belt warning light t". •
Adaptive Air Suspension
The warning/indicator light illuminates, when the jacking mode
has been activated ~ page 191. This warning/indicator light has the
following functions:
• It illuminates for a few seconds after the ignition is turned on as
function check and then goes out .
• If the warning/indicator light illuminates steadily, there is a
system fault in the Adaptive Air Suspension . A system fault can
r esult in lim ited ride comfort and
low ground clearance . The fault
should be corrected as soon as possib le by an authorized Audi
dea ler .
• If the warning/indicator light flashes, you should not drive the
vehic le . The flashing warning/indicator light points to an extreme
High level. A very pronounced lifting of the vehicle (extreme High
level) can resu lt, for examp le, when a heavy load is removed from
the vehic le . As soon as the level has returned to normal, the
warning/indicator light stops flashing , and you can drive away .
• If the warning/indicator light flashes in conjunction with the~
warning/indicator light, you should not drive off immediately in
order to prevent damage to the underbody . The two warning/indi­
cator lights flashing together points to an extreme Low level. A very
pronounced lowering of the vehicle (extreme Low level) can result,
for example , from a heavy load. As soon as the level has returned to
normal, the warning/indicator lights stop flashing, and you can
drive away .
0 Note
If the warning/indicator light flashes in conjunction with the~
warning/indicator light, you should not drive the vehicle because
l ow -lying vehicle parts can bottom out as you drive over uneven
ground and be damaged as a result.•

Tire pressure monitoring system
Applies t o vehi cle s: with n re pre ss ure moni toring sys te m
General notes I)
Each tire, including the spare (if provided}, should be checked
month ly when cold and inflated to the inflation pressure recom­
mended by the vehicle manufacturer on the vehicle placard or tire
inflation pressure label. (If your vehicle has tires of a different size
than the size indicated on the vehicle placard or tire inflation pres ­
sure label, you should determine the proper tire inflation pressure
for those tires.}
As an added safety feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMSl that illuminates a low tire pressure tellta le when one or more of your tires is significantly
under-inflated . Accordingly, when the low tire pressure te lltale i llu ­
minates, you should stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving on a significantly
under -inflated tire causes the tire to overheat and can lead to tire
Controls and equip ­
ment
Dr ive r informat ion di spl ay
failure . Under -inflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle's handling and s topping ability.
Please note that the TPMS is not a substitute for proper tire mainte ­
nance, and it is the driver 's responsibility to maintain correct tire
pressure, even if under-inflation has not reached the leve l to trigger
illumination of the TPMS low tire pressure te lltale.
Your vehic le has a lso been equipped with a TPMS malfunction indi­
cator to indicate when the system is not operating proper ly. The
TPMS ma lfunction indicator is combined w ith the low ti re p ressure
tel ltale . When the system detects a malfunction , the telltale wil l
flash for approximately one minute and then remain continuously
il luminated . This sequence will cont inue upon subsequent vehicle
start -ups as long as the malfunction exists.
When the ma lfunction indicator is illuminated, the system may not
be able to detect or signal low tire pressure as intended . TPMS
mal functions may occur for a variety of reasons, including the
insta llation of replacement or alternate tires or wheels on the
vehic le that prevent the TPMS from funct ioning properly. A lways
check the TPMS malfunction tellta le after replacing one or more
tires or whee ls on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to function
properly. •

Introduction
The tire pressure monitoring system moni tors air pressure
in all four roa d wheels and the spare tire* while the
vehicle is moving.
As soon as the tire pressure monitoring system senses a significant loss of air pressure in one o r severa l tires, text messages and yellow
symbo ls appear in the instrument cluster display to alert the driver.
The L warni ng light in the instrument cluster comes on when the
tire is significantly underinflated
=> page 20. _,,
I • •

Driver inf ormati on displ ay
The warning light n also illuminates in the case of a system
mal fu n ction.
The system continuously receives radio signals from sensors located inside each tire .
Be aware that tire pressure is also dependent on the temperature of
the tire. For every 18 °F (10 °C) increase in tire temperature, tire pres­
sure increases by about
1 .5 psi (0.1 bar). The tire warms up while the
vehic le is moving and tire pressure rises. So you should adjust tire
pressure only when the tires are
cold, when the temperature of the
tires is roughly the same as the ambient air temperature .
In order to keep the tire pressure monitoring system properly cali ­
brated, tire pressure on al l four tires and on the spare tire * should
be checked at regular intervals, adjusted if necessary and sav ed in
the proper setting (recommended pressure) =>
page 44.
The tire pressure is shown on the tire pressure label. On USA vehi­
cles, the tire pressure label is located on the driver's side B -pi llar. On
Canada vehicles, the tire pressure labe l is located either on the
driver's side B -pil lar or inside the fuel filler flap . The tire pressu re
label lists the recommended cold t ire inflat ion pressures for the
vehic le at its maximum capacity weight and the tires that were on
your vehicle at the time it was manufactured . For recommended tire
pressures for normal load conditions, please see chapter
=>
page 330 .
The current temperatures and pressure of your tires can be viewed
i n the MMI =>
page 44.

Driving with under -inflated tires reduces fuel efficiency and tire
tread life.
[ i ] Tips
• Each tire, includin g the sp are*, should be checked monthly when
cold and set to the recommended inflation pressure as specified on
the tire pressure label=>
page 330.
• T he tire pressure monitoring system he lps the d river to keep an
eye on tire pressures . But the dr iver st ill has the responsibility for
maintaining the correct tire pressure .
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• When tires are replaced, the sensors and valves shou ld not be
detached or exchanged . Only the valve core needs to be replaced
and, if necessary, the va lve and the wheel electronics replaced .
• If you should put different whee ls and tires on your vehicle (e.g .
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire pressure monitoring system. Otherwise the system will register a ma lfunction and a fault
message will be displayed. For more information , contact your
authorized Audi dea ler.
• Adjust the tire pressure and store the pressure in the tire pres ­
sure mon itor ing system to the load you are carrying=>

[ i ] Tips
• In the case of an intentional loss of air pressure, for example,
when re -adjusting tire pressure, this has to be stored again after ­
wards =>
page 44.
• Current information about tire pressures and temperatures can
be scanned in MMI
~ page 44.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• The yellow symbol disappears, when the tire pressure is
corrected and the new pressure is stored in the system~
page 44.
• After changing a wheel you have to adjust the t ire pressures on
al l whee ls. In addition, you must then initialize the new tire pres­
sures in the tire pressure monitoring system~
page 45.
• If your vehicle is equipped with a spare tire* with a wheel sensor,
the tire will be monitored and the display symbols~ fig. 25 or

Applies to vehicles: with Tire pressure mon itor ing system
Storing tire pressures
Correct storage of specified pressure is the basic require­
men t for reliable tire pressure monitoring.
In order for the tire pressure mo nito ring system to ope rate
appropr iately, yo u have to re -save the specified pressures
whenever yo u adjust tire pressure, for example when the
load condition of your vehicle changes. Proceed as follows:
Corr ecting t ir e pres sure
- Check the pressure in the tires (including the spare tir e*). ~

-Adjust air pressure as needed in acco rdance with the
informat io n on the label located either on the driver's
side B -pillar (visible w hen the door is open), inside the
fuel filler flap and addi tionally in t he manua l.
Saving tir e pres sur es

-Select Store curr. tire pres sures :::} page 44, fig. 27 .
All pressure warning indicators in the display will be canceled .
Following each intentional change in specified pressures, tire pres ­
sures must be resaved .
After the pressures are saved, the tire pressure monitoring system measures the current tire pressures and saves them as the new
specified pressures.
[ i ] Tip s
• T he t ire pressure is shown on the tire pressure label. On USA
vehic les, the tire pressure label is located on the driver's side 8 -
pillar. On Canada vehicles , the tire pressure labe l is located e ither on
the driver's side 8 -pillar or inside the fuel filler flap. The tire pressure
label lists the recommended cold tire inflation pressures for the
vehicle at its maximum capacity weight and the tires that were on
your vehicle at the time it was manufactured . For recommended tire
pressures for normal load conditions, please see chapter
