Wheels
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 Rat­
ing
("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
l uggage 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.
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
296
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 l uggage .
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
¢ page 293,
fig. 266.
_& 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
from handling properly and increase 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.

cle.
.,.Check the tire sidewall
(¢ page 283, fig. 264) 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 .
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 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 314.
- 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 .
Winter tires
Winter tires significantly improve the vehicle's
handling when driving in winter conditions. Be­
cause of their construction (width, compound,
tread pattern) , summer tires provide less trac­
tion on ice and snow.
298
.. Use winter tires on all four wheels .
.. Only use winter tires that are approved for your
vehicle.
.. Please note that the maximum permitted
speed may be lower with winter
tires¢ _&.. An
authorized Audi dealer or authorized Audi Serv ­
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after installing wheels
¢page 293 .
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0.157 in (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages , re­
gardless of the remaining tread.
A WARNING
- Never drive faster than the maximum per­
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
the risk of an accident because it can cause
the tire to burst .
- Always adapt your driving to the road and
traffic conditions. Drive carefully and reduce
your speed on icy or slippery roads. Even
winter tires can lose traction on black ice .
® For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumption.
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires with the
& symbol may be per­
mitted.
Snow chains
-
Snow chains not only improve the driving in win­
ter road conditions, but also the braking.
.,. Only install snow chains on the front wheels. .,.

Weights
Gross Vehicle Weight Rating
The Gross Vehicle Weight Rating (GVWR), and
the Gross Axle Weight Rating (GAWR) for front
and rear are listed on a sticker on the door jamb
on the driver's side .
The Gross Vehicle Weight Rating includes the
weight of the basic vehicle p lus full fuel tank, oi l
and coolant, plus maximum load, which includes
passenger weight (150 lbs/68 kg per designated
seating position) and luggage
we ight¢ &..
Gross Axle Weight Rating
The Gross Ax le Weight Rating is the maximum
load that can be applied at each axle of the vehi ­
cle
¢ &. .
Vehicle capacity weight
The vehicle capacity weight (max. load) is listed
either on the driver's side B-pillar or inside the
fue l filler f lap .
A WARNING
- The actual Gross Axle Weight Rating at the front and rear axles should not exceed the permissible weights, and their comb inat ion
must not exceed the Gross Veh icle Weight
Rating .

Approximate capaci-
ties

- Exceed ing permissible weight ratings can
result in vehicle damage, accidents and per­
sonal injury.
@ Note
- The veh icle capacity weight figures apply
when the load is d istr ibuted evenly in the
vehicle (passengers and luggage) . When
transport ing a heavy load in the luggage
compartment, carry the load as near to the
rea r axle as possible so that the vehicle's
hand ling is not impai red.
- Do not exceed the maximum permissible
ax le loads or the maxim um gross vehicle
we ight . A lways remember that t he ve hicle's
handling will be affected by the extra load.
Th erefore, adjust your speed accordingly .
- Always observe local regulations .
