If the tire pressure monitoring indicator
appears
Applies to: vehicles with Tire Pressure Monitoring System in-
dicator
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Using the ABS sensors, the tire pressure monitor-
ing system compares the tire tread circumference
and vibration characteristics of the individual
tires. If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light (J and a message.
If only one tire is affected, the location of that
tire will be indicated.
The tire pressures must be stored again each
time you change the pressures (switching be-
tween partial and full load pressure) or after
changing or replacing a tire on your vehicle
= page 308. The tire pressure monitoring system
only monitors the tire pressure you have stored.
Refer to the tire pressure label for the recom-
mended tire pressure for your vehicle
=> page 299, fig. 190.
Tire tread circumference and vibration character-
istics can change and cause a tire pressure warn-
ing if:
— The tire pressure in one or more tires is too low
— The tires have structural damage
— The tire was replaced or the tire pressure was
changed and it was not stored > page 308
— Tires that are only partially used are replaced
with new tires
Indicator lights
If the @ indicator light turns on, there is a loss
of pressure in at least one tire .> A\ Check the
tires and replace or repair if necessary. Check and
correct
the pressures of all four tires and store
the pressure again > page 308.
ia Tire pressure: malfunction! See owner's
manual
if io appears after switching the ignition on or
while driving and the @ indicator light in the in-
strument cluster blinks for approximately one
308
minute and then stays on, there is system mal-
function. Try to store the correct tire pressures
= page 308. In some cases, you must drive for
several minutes after storing the pressures until
the indicator light turns off. If the indicator light
does turn off or turns on again after a short peri-
od of time, drive to an authorized Audi dealer or
authorized Audi Service Facility immediately to
have the malfunction corrected.

Z\ WARNING
— If the tire pressure indicator appears in the
display, reduce your speed immediately and
avoid any hard steering or braking maneu-
vers. Stop as soon as possible and check the
tires and their pressure.
— The driver is responsible for maintaining the
correct tire pressure. You must check the
tire pressure regularly.
— Under certain conditions (such as a sporty
driving style, winter conditions, or unpaved
roads), the tire pressure monitoring system
indicator may be delayed.

G) Tips
—The tire pressure monitoring system can al-
so stop working when there is an ESC mal-
function.
— Using snow chains may result in a system
malfunction.
—The tire pressure monitoring system in your
Audi was calibrated with “Audi Original
Tires” > page 296. Audi recommends using
these tires.
Storing tire pressures
Applies to: vehicles with Tire Pressure Monitoring System in-
dicator
If the tire pressure changes or a tire is replaced,
it must be confirmed in the MMI.
> Before storing the tire pressures, make sure the
tire pressures in all four tires meet the speci-
fied values and are adapted to the load
> page 299.
> Switch the ignition on.
>» Applies to MMI: Select on the home screen: VE-
HICLE > Settings & Service > Tire pressure >

Emergency assistance

> Set the parking brake.
> Select the “P” position.
>» When towing a trailer: disconnect the trailer
from your vehicle.
> Lay out the vehicle tool kit > page 317 and the
spare tire > page 323.
» Applies to MMI: Select on the home screen: VE-
HICLE > Settings & Service > Air suspension:
wheel change.
> Switch the ignition off.

ZA\ WARNING
The vehicle must also be secured to prevent it
from rolling when using the vehicle jack”. Use
suitable objects to block the front and back of
the wheel that is diagonal from the wheel
with the flat tire.

4N0012721BF
Emergency assistance

> Slide the wheel wrench* from the vehicle tool
kit all the way onto the wheel bolt).
> Turn the wheel bolt approximately one turn to
the left. To achieve the required torque, hold
the end of the wheel wrench*. If the wheel bolt
will not loosen, press carefully on the wheel
wrench* with your foot. Hold onto the vehicle
securely while doing this and make sure your
footing is stable.

Z\ WARNING
To reduce the risk of an accident, only loosen
the wheel bolts gently one turn before raising
the vehicle with the vehicle jack*.
Raising the vehicle
Applies to: vehicles with vehicle jack








RAZ-0257,

Fig. 200 Sill: positioning the vehicle jack
> Place the vehicle jack from the vehicle tool kit
ona firm surface. Use a flat, stable support if
necessary. On a slippery surface such as tile,
you should use a non-slip pad such as a rubber
mat > /\.

D_ You need the matching adapter in order to loosen and
tighten anti-theft wheel bolts* > page 320.
> Find the marking on the sill that is closest to
the tire that will be changed > fig. 199. Behind
the marking, there is a lifting point on the side
sill for the vehicle jack.
> Turn the vehicle jack located under the lifting
point on the sill to raise the jack until its arm @
=> fig. 200 is located under the designated plas-
tic mount.
> Align the vehicle jack so the arm (@) engages in
the designated lifting point in the door sill and
the movable base (2) lies flat on the ground.
The base @) must be directly under the mount-
ing point @.
> Continue raising the vehicle jack until the wheel
lifts off the ground slightly.

Z\ WARNING
—To reduce the risk of injury, make sure no
one is in the vehicle before raising it.
— Make sure the vehicle jack is stable. The risk
of injury is increased when the ground is
slippery or soft, because the vehicle jack
could slide or sink.
— Only raise your vehicle with the vehicle jack
provided by the factory. If you use a vehicle
jack designed for another vehicle, your vehi-
cle could slip and cause injury.
— Position the vehicle jack only at the desig-
nated mounting points on the side sill and
align the jack. Otherwise, the vehicle jack
could slip and cause an injury if it does not
have sufficient hold on the vehicle.
—To reduce the risk of injury, do not raise any
other vehicles or other loads using the vehi-
cle jack provided by the factory.
— Changes in temperature or load can affect
the height of the vehicle.
— To reduce the risk of an accident, never start
the engine when the vehicle is raised.
—To reduce the risk of injury, no work should
be performed under the vehicle while it is

raised.
