AUDI TT ROADSTER 2011 Owners Manual

Your vehicle is equipped with a tire repair kit,
the
Tire Mobility System (TMS)*.
In the event of a tire fa ilu re, the TMS is in the
l uggage compartment under the floor.
It con ­
sists of the tire sea lant and an electric a ir
pump .
Using
TMS , tire damage caused by foreign
bod ies up to abou t
0.16 inch (4 mm) in diam­
eter can be sealed reliab ly.
The foreign object can stay in the t ire.
The tire sealant must not be used:
-for cuts or punctures in the tire which are
larger than 0.16 inch (4 mm)
c> fig. 159 (D
- for damage to the rim@
- if you have been driving with very low tire
pressures or tires with no air @
Using the
TMS is desc ribed in the section
c> page 220, Preliminary steps.
TMS can be used at temperatures dow n to -
4 °F (- 20 °().
A WARNING
Take the following precautions after re ­
pairing the tire:
-
- Do not drive faster than 50 mph (80 km/
h)!
- Avoid full-throttle acce le rat ion, heavy
braking and fast cornering.
- T he veh icle's road behavior can be affect­
ed.
- T ires sealed with
TMS a re intended only
for
temporary, short-term use.
- After using the tir e sea lant the tire pres­
sure monitoring system may no longer
work prope rly. Drive carefully to the next
professional repair facility .
-TMS mus t NOT be used,
- for cuts or punctures in the tire which are larger than 0.16 inch (4 mm)
- for damage to the rim
- if you have been driving with very low
tire pressures or tires with no air
What do I do now? 219
-Seek professional assistance if it is not
possible to repa ir the tire w ith the t ire
sealant.
A WARNING
The tire sealant must not come into con­
tact with skin, eyes or clothing.

to tu rn . Check for d irt and corrosion on
the mat ing s urfaces of both the wheel
and the hub. Rem ove a ll dirt from these
su rfaces before rem ounting the wheel.
Notes on wheel change
Please read the information <=> page 205 , New
tires and replacing tires and wheels ,
if you are
going to use a spare t ire which is different
from the tires on your ve hicle.
Afte r you change a tire :
What do I do now? 225
-Check the tire pre ssure on the spare imme­
diately after mounting.
- Have the whe el bolt tightening torque
checked with a torque wrench as soon a s
possible by your authorized Audi dealer or
a qualified service station.
- With steel and alloy wheel rim s, the wheel
bolt s are cor rectly tightened at a torque of
90 ft lb (120 Nm ).
- If you noti ce while changing a tire that the
wheel bolts are corroded and difficult to
turn , then they should be replaced before
you check the tightening to rque.
- Replace the flat tire w ith a new one and
have it installed on your vehicle as soon as
possible. Remount the whee l co ver.
Until then , dr ive with extra care and at re­
duced speeds.
