be five 150 lbs. passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 x 150) = 650
lbs.)

Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces. These compo-
nents were bolted together using special bolts
and a special procedure. You must not repair or
disassemble them > A\.

Z\ WARNING
Wheel bolts that are tightened or repaired in-
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi-
cation, see > page 277, Finishing.
— Always keep the wheel bolts and the threads
in the wheel hub clean and free of grease.
— Only use wheel bolts that fit the rim.
— Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident.
Loose wheel warning
Applies to: vehicles with loose wheel warning
Within the limits of the system, the loose wheel
warning in the instrument cluster warns you if
one or more wheels are loose.
Using the ABS sensors, the loose wheel warning
system compares the vibration characteristics of
the individual tires. If one or more wheels are
loose, it will be indicated in the instrument clus-
ter display with the fi indicator light and a mes-
sage. If only one wheel is affected, the location
of that wheel will be indicated.
Messages
fi Wheel bolts loose. Please safely stop the ve-
hicle and check all wheel bolts!
Loose wheel warning for at least one wheel > A\.
Check the wheel bolts on all wheels with the
wheel wrench (vehicle tool kit). Have the tighten-
ing specification checked as soon as possible with
a torque wrench. Drive carefully until then. For
the correct tightening specification, see
=> page 277, Finishing.
fl Wheel assessment active. Please continue
driving carefully
After this message appears and you have checked
the wheel bolts, the assessment phase begins
when the vehicle is in motion. This may take sev-
eral minutes.

the end of the wheel wrench. If the wheel bolt
will not loosen, press carefully on the wheel
wrench with your foot. Hold onto the vehicle se-
curely while doing this and make sure your foot-
ing is stable.
ZA WARNING
To reduce the risk of an accident, only loosen
the wheel bolts gently one turn before raising

Removing a wheel
> Remove the top wheel bolt completely using
the hex socket in the screwdriver handle from
the vehicle tool kit > fig. 175 and place it ona
clean surface.
> Then install the alignment pin from the vehicle
tool kit by hand in the empty wheel bolt hole
> fig. 176”.
> Remove the rest of the wheel bolts.
> Remove the wheel >(). The alignment pin re-
mains in the hole while doing this.
Installing a wheel
Read the directions on > page 277 when instal-
ling unidirectional tires.
> Slide the wheel on over the alignment pin >@.
> Install the wheel bolts and tighten them gently
using the hex socket.
> Remove the alignment pin and tighten the re-
maining wheel bolt.
D Applies to: vehicles with ceramic brake rotors*: Use a sec-
ond alignment pin* from the vehicle tool kit for the lowest
hole according to the steps described for the first align-
ment pin.
> Carefully lower the vehicle using the vehicle
jack*.
> Tighten the wheel bolts in a diagonal pattern
using the wheel wrench.
The wheel bolts must be clean and loosen and
tighten easily. Check the contact surfaces for the
wheel and hub. Contaminants on these surfaces
must be removed before installing the wheel.
Z\ WARNING
— Read and follow the important information
and notes under > page 252.
— Never use the hex socket in the screwdriver
handle to tighten the wheel bolts. Using the
hex
socket will not achieve the required
tightening torque, which increases the risk
of an accident.
(!) Note
When removing or installing the wheel, the
rim could hit the brake rotor and damage the
rotor. Work carefully and have a second per-
son help you.
Unidirectional tires
A unidirectional tire profile is identified by arrows
on the tire sidewall that point in the running di-
rection. You must always maintain the specified
running direction. This is necessary to ensure the
tire's optimal performance in regard to adhesion,
running noise, and friction, and to reduce the risk
of
hydroplaning.
To benefit fully from the advantages of the uni-
directional tire design, you should replace faulty
tires as soon as possible and restore the correct
running direction on all of the tires.
> Reinstall the caps on the wheel bolts if necessa-
ry.
277
Emergency assistance
> Store the vehicle tool kit in its designated
place.
> If the removed wheel does not fit in the spare
wheel well, store it securely in the luggage
compartment > page 81.
> Check the tire pressure on the installed wheel
as soon as possible.
> Correct the tire pressure and store it in the MMI
=> page 264.
> The wheel bolt tightening specification must be
90 ft lbs (120 Nm). Have it checked as soon as
possible with a torque wrench. Drive carefully
until then.
> Have the faulty wheel replaced as quickly as
possible.
Space-saving spare tire
Applies to: vehicles with space-saving spare tire (compact
spare tire)
The spare tire is intended for short-term use only.
Have the damaged tire checked and replaced if
necessary by an authorized Audi dealer or author-
ized Audi Service Facility as soon as possible.
There are some restrictions on the use of the
compact spare tire. The compact spare tire has
been designed specifically for your type of vehi-
cle. Do not replace it with the spare tire from an-
other type of vehicle.
The compact spare tire is located in the luggage
compartment under the cargo floor cover
=> page 272.
The tire pressure must be adjusted to a specified
value listed on the tire pressure sticker
=> page 255, fig. 165.
Snow chains
For technical reasons, the use of snow chains on
the
compact spare tire is not permitted.
If you have to drive with snow chains and a front
tire fails, mount the 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.
278
AN WARNING
— After installing a spare tire, the tire pressure
must be checked as soon as possible.
— Do not drive faster than 50 mph (80 km/h)
with a compact 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 compact spare tire.
—To reduce the risk of an accident, never drive
with more than one compact spare tire.
— Normal summer or winter tires must not be
mounted on the compact spare wheel rim.
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 272 and
the compressor must be laid out.
Removing
> Lift the cargo floor using the handle.
> Turn the handwheel counter-clockwise and re-
move it.

You must inflate the collapsible spare tire before-
hand in order to use it.
Inflating
> Remove the valve cap from the collapsible
spare tire.
