spare tire location AUDI TT ROADSTER 2018 Owners Manual

Wheels
For unidirectional tires, make
sure the tires are installed a ccord­
ing to the running direction indi­
cated on the tire sidewall
¢ page 278.
Hidden damage
Damage to tires and rims can of ­
ten occur in locations that are
hidden. Unusual vibrations in the
vehicle or pulling to one side may indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage. If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi deal­
er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed.
_& WARNING i-==
Tread that has worn too low or different tread depths on the
tires can reduce dr iving safety.
This can increase the risk of an
accident because it has a nega­
t ive effect on handling, driving
through curves, and braking,
and because it increases the
risk of hydroplaning when driv­
ing through deep puddles.

The correct tire pressure for tires
mounted in the factory and for
the spare tire* is indicated on a la­ bel. The label is located on the B­
pillar
¢ fig. 189, ¢ fig. 190.
Use the tire pressure specified for
a normal vehicle load when the
vehicle is partially
loaded ¢ table
on page 256.
If driv ing the vehi-
cle when fully loaded, you must increase the tire pressure to the
maximum specified
pressure ¢ A . ..,.

Tire pressure monitoring system
(J_) General notes
Each tire, incl uding the spare (if provided),
should be checked month ly when co ld and inflat­
ed to the inf lation pressure recommended by the
ve hicle manufacturer on the vehicle placard or
tire inflat ion pressure label. (If your vehicle has
tires of a d ifferent s ize tha n the s ize indicated on
the veh icle placa rd or t ire inflation pressure la­
be l, you s hou ld determine the prope r tir e infla­
tion pressure fo r th ose tires).
As an added safety feature, your ve hicle has been
equ ipped w ith a t ire pressu re monito ring system
(TPMS) that ill uminates a low tire p ress ure tell­
tale whe n one or more of yo ur t ires is sign ificant ­
l y unde r-infla ted. Accord ingly, whe n the low tire
p ressure tellta le illuminates, yo u should stop and
check your tires as soon as possible, and inflate
them to the proper press ure. D riving on a signifi ­
cantly under-inflated tire causes the tire to ove r­
h eat and can lead to t ire failure. Under-inflation
a lso reduces fuel efficiency and ti re tread life,
and may affect the veh icle's handling and stop­
p ing ability .
P lease note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsib il ity to ma inta in correct tire pressure,
even if u nder-inflation has not reached t he leve l
to tr igger illum inat io n of t he TPM S low tire p res ­
sure telltale.
Your veh icle has also been equ ipped w ith a TPMS
malfunct ion ind icator to indicate when the sys­
tem is not operat ing properly. The TPMS ma l­
f u nction ind icator is combined w ith the low tire
p ressure tellta le. Whe n the system det ects a
mal function, the te lltale wi ll flash fo r approxi ­
mate ly one mi nute and then remain continuous ly
illum inated. This sequence will continue upon
subseq uent ve hicle start-ups as long as the ma l­
function ex ists .
W hen t he malfunctio n indicator is ill uminated,
the system may not be ab le to detect or signa l
low t ire press ure as intended. TPMS ma lfunctions
may occur for a var iety of reasons, including the
Wheels
insta llation o f replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning p roperly . Always check the
TPMS ma lfunction te lltale after replac ing one or
more tires or wheels on you r vehicle to ensure
t h at the rep lacement or a lternate tires a nd
wheels allow t he TPMS to continue to function
prope rly.
If the Tire Pressure Monitoring System
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.
U sing the ABS se nsors, the t ire pressure monitor­
ing system compares the tire tread c ircumfer­
ence and v ibration characterist ics of the ind ividu­
al tires. If the pressu re changes in one o r more
t ir es, th is is indica ted in the Info tainment sys tem
display wi th an indica to r li ght
ti] and a message.
If only one ti re is affected, the location of tha t
tire will be indicated.

me nt system agai n ea ch t ime t he p ressures

have stored. Refer to the t ire pressure label for
the recommended t ire pressure for your vehicle

Tire tread c ircumference and vibration character ­
