Collapsible spare tire
Applies to: vehicles with collapsible spare tire
The collapsible spare tire is intended for short-
term use only. Have the damaged tire checked
and replaced if necessary by an authorized Audi
dealer or authorized Audi Service Facility as soon
as possible.
There are some restrictions on the use of the col-
lapsible spare tire. The collapsible spare tire has
been designed specifically for your type of vehi-
cle. Do not replace it with the collapsible spare
tire from another type of vehicle.
The collapsible spare tire is located in the lug-
gage compartment under the cargo floor cover.
Requirement: the vehicle tool kit > page 253 and
the compressor must be laid out.
Removing
> Lift the cargo floor using the handle.
> Turn the handwheel counter-clockwise and re-
move it.
> Remove the collapsible spare tire.
You must inflate the collapsible spare tire before-
hand in order to use it.
Inflating
> Remove the valve cap from the collapsible
spare tire.
> Tighten the compressor hose on the collapsible
spare tire valve.
> Connect the compressor hose to a vehicle sock-
et and switch it on.
> Let the compressor run until the specified value
on the tire pressure sticker is reached
> page 237, fig. 171 > ©.
> Screw the valve cap back onto the valve.
Returning to storage
> To release air, turn the valve insert. See an au-
thorized Audi dealer or authorized Audi Service
Facility.
> Turn the valve insert back once the air has been
released.
> Wait several hours before placing the collapsi-
ble spare tire in the spare wheel well. Only then
will it fold down completely so that you can
store it securely.
> Then screw the valve cap back onto the valve.
> Secure the collapsible spare tire with the hand-
wheel.
> Fold the cargo floor cover back into place.
Snow chains
Using snow chains on the collapsible spare tire is
not permitted for technical reasons.
If you have to drive with snow chains and a front
tire fails, mount the collapsible spare tire in place
of a rear tire. Install the snow chains on the rear
tire that you removed, and install that in place of
the front tire that failed.

ZA\ WARNING
— Only use the collapsible spare tire in emer-
gencies and drive very carefully, especially if
it is more than six years old.
— The compressor and the hose can become
very hot during operation which increases
the risk of burn injuries.
— After installing a collapsible spare tire, the
tire pressure must be checked as quickly as
possible to reduce the risk of an accident.
— Do not drive faster than 50 mph (80 km/h)
with the collapsible spare tire. Driving faster
than that increases the risk of an accident.
—To reduce the risk of an accident, avoid hard
acceleration or braking and driving fast
around curves with the collapsible spare
tire.
— Never drive using more than one collapsible
spare tire, because this increases the risk of
an accident.
— Normal tires or winter tires must not be
mounted on the collapsible spare tire rim.
@) Note
The compressor must be switched off after six
minutes at the most to reduce the risk of
overheating. Let the compressor cool down
for several minutes before using it again.
