Emerg enc y assis tance
There are some restrictions on the use of the
spare tire. The spare tire has been designed spe ­
cifically for your type of vehicle. Do not replace it
with the spare tire from another type of vehicle.
S pac e-s av ing sp are tir e*
The tire pressure must be 61 PSI (4.2 bar).
Remov ing th e spar e tire
.,. Fold the cargo floor up to the rear bench seat .
.,. Turn the handwheel counter-clockw ise and re-
move it .
.,. Remove the spare t ire.
Snow chains
Using snow chains on the spare tire is not perm it ­
ted due to technical reasons .
If you have to drive with snow chains and a front
tire fa ils, mount the spare t ire in place of a rear
tire . Install the snow cha ins on the rear tire that
you removed, and install that in place of the
front tire that failed.
A WARNING
-
- After installing a spa re t ire, the tire p res­
s u re must be checked as quickly as poss ible.
- Do not drive faster than SO mph (80 km/h)
with a spare tire. Driv ing faster than that in­
creases the risk of an a ccident.
- Avoid full-throttle accelerat ion, heavy b rak­
ing, and fast cornering, because this in­
creases the risk of an accident.
- Never dr ive using more than one spa re t ire,
because th is increases the r isk of an acci­
dent.
- Norma l tires o r winter tires m ust not be
mounted on the spare tire rim .
- Only use the co llapsible spare tire in emer­
gencies and dr ive very carefu lly, especially if
it is more than 6 years o ld .

Therefo re, proof of servicing in accordance w ith
the ma intenance sc hedule may be a condition fo r
up hold ing a possible wa rra nty claim made wi thin

Above all , operational safety can be adversely af­
fected, c reating unnecessa ry risks fo r you and
your p assengers.
If in doubt about any servicing, have it done by
your author ized Audi dealer or any other properly
eq uipped and qualified workshop . We strongly
urge yo u to g ive your author ized Audi dealer the
