loss of vehicle control, but can al-
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas-
sengers also depends on making
sure that load limits are not ex-
ceeded. Vehicle load includes ev-
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi-
cle’s Gross Vehicle Weight Rating
(“GVWR”).
The “GVWR” includes the weight
of the basic vehicle, all factory in-
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
plus maximum load. The maxi-
mum load includes the number of
passengers that the vehicle is in-
tended to carry (“seating capaci-
ty”) with an assumed weight of
150 lbs. (68 kg) for each passen-
ger at a designated seating posi-
tion and the total weight of any
luggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ-
ed as part of the vehicle load.
302
The Gross Axle Weight Rating
(“GAWR”) is the maximum load
that can be applied at each of the
vehicle’s two axles.
The fact that there is an upper
limit to your vehicle’s Gross Vehi-
cle Weight Rating means that the
total
weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas-
sengers in the vehicle or passen-
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as
luggage.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli-
ance sticker label located on the
driver’s side B-pillar.

Z\, WARNING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per-
sonal injury, and even death.
—Carrying more weight than
your
vehicle was designed to
carry will prevent the vehicle [>

4N0012721BD
Wheels


from handling properly and in-
crease the risk of the loss of
vehicle control.
—The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
—Tires on a vehicle that has
been overloaded can fail sud-
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
—Always make sure that the to-
tal load being transported -
including the weight of a trail-
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle’s
Gross Vehicle Weight Rating.

Determining correct load
Talis
Use the example below to calcu-
late the total weight of the pas-
sengers and luggage or other
things that you plan to transport
so that you can make sure that
your vehicle will not be overload-
ed.
Steps for Determining Correct
Load Limit
1. Locate the statement “THE
COMBINED WEIGHT OF OCCU-
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS” on your vehicle’s placard
(tire inflation pressure label)
> page 299, fig. 192.
2. Determine the combined
weight of the driver and pas-
sengers that will be riding in
your vehicle.
3. Subtract the combined weight
of the driver and passengers
from “XXX” kilograms or “XXX”
pounds shown on the sticker
=> page 299, fig. 192.
4. The resulting figure equals the
available amount of cargo and
uggage load capacity. For ex-
ample, if the “XXX” amount
equals 1400 lbs. and there will
be five 150 lbs. passengers in
your vehicle, the amount of
available cargo and luggage
oad capacity is 650 lbs.
(1400-750 (5 x 150) = 650
bs.)
5. Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely

Wheels

exceed the available cargo and
luggage load capacity calculat-
ed in Step 4.
6. If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your vehi-
cle. Consult this manual to de-
termine how this reduces the
available cargo and luggage
load capacity of your vehicle.
> Check the tire sidewall
(=> page 290, fig. 189) to deter-
mine the designated load rating
for a specific tire.
Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily. You will need a special adapter to loosen
the anti-theft wheel bolts* > page 319.
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\.

ZA 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 322, 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

304

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 322, Finishing.
fi 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.
& Loose wheel warning: malfunction! See
owner's manual
There is a system malfunction. Drive immediately
to an authorized Audi dealer or authorized Audi
Service Facility to have the malfunction repaired.

ZA\ WARNING
Wheel bolts that are tightened incorrectly can
become loose and result in loss of vehicle con-
trol, which increases the risk of an accident.
— If a message appears, reduce your speed im-
mediately and avoid any hard steering or >
