Wheels

minute and then stays on, there is system mal-
function. Try to store the correct tire pressures
= page 276. Insome 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.

ZA\ 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.

(i) 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 263. 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 266.
> Switch the ignition on.
> Applies to MMI: Select on the home screen: VE-
HICLE > Settings & Service > Tire pressure
276
monitoring > Store tire pressure > Yes, store
now.
@) Tips
Do not store the tire pressures if snow chains
are installed.
Tire pressure monitoring
system
(1) General notes
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat-
ed to the inflation pressure recommended 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 pressure la-
bel, you should determine the proper tire infla-
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a Low tire pressure tell-
tale when one or more of your tires is significant-
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving ona signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop-
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re-
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres-
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys-
tem is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously >

Fuses and bulbs


This can cause damage to the electrical sys-
tem and increases the risk of fire.
() Note
If a new fuse burns out again shortly after you
have installed it, have the electrical system
checked as soon as possible by an authorized
Audi dealer or authorized Audi Service Facili-
ty.
