2015 AUDI S6 trailer

248 Tires and wheels
Remember, your safety and
that of your passengers also de­ pends on making sure that load
limits are not exceeded . Vehicle
load includes everybody and ev­
erything in and on the vehicle.
These load limits are technical­
ly referred to as the vehicle's
Gross Vehicle Weight Rating ("GVWR"). The Gross Axle
Weight Rating ("GAWR") is the
maximum load that can be ap­
plied at each of the vehicle's
two axles. The Gross Vehicle
Weight Rating and the Gross
Axle Weight Rating are listed
on the safety compliance stick­
er label located on the driver's
side B-pillar. The tire pressure
label on your Audi lists the
maximum combined weight of
all of the occupants and lug­
gage or other cargo that the ve­
hicle can carry. For the location
of the tire pressure label

.&_ WARNING
-
Overloading a vehicle can
cause loss of vehicle control,
a crash or other accident, se­
rious personal injury, and
even death. -Carry
ing more weight than
your vehicle was designed to carry will prevent the ve­
hicle from handling properly
and increase the risk of a
loss of vehicle control.
-The brakes on a vehicle that
has been overloaded may not be able to stop the vehi­
cle within a safe distance.
-Tires on a vehicle that has
been overloaded can fail
suddenly causing loss of
control and a crash.
-Always make sure that the total load being transported
- inclu ding the weight of a
trailer hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rat­
ing.
A WARNING
-Incorrect tire pressures
and/or underinflation can lead to a serious or fatal ac­
cident.
-Inco rrect tire pressures
and/or underinflation cause
increased tire wear and can .,.

The "GVWR" includes the
weight of the basic vehicle, all
factory installed accessories, a
full tank of fuel, oil, coolant and other fluids plus maximum
load. The maximum load in­
cludes the number of passen­
gers that the vehicle is intend­
ed to carry ("seating capacity")
with an assumed weight of 150 lbs (68 kg) for each pas­
senger at a designated seating
position 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 included 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 Gross Vehicle Weight Rat­ ing and the Gross Axle Weight Rating are listed on the safety
compliance sticker label locat­
ed on the driver's side B-pillar.
Your Audi has 5 seating posi­
tions, 2 in the front and 3 in the rear for total seating capacity
of 5. Each seating position has
Tires and wheels 253
a safety belt¢ page 136, Safe­
ty belts.
The fact that there is an upper
limit to your vehicle's Gross Ve­
hicle Weight Rating means that
the total weight of whatever is being carried in the vehicle (in­
cluding the weight of a trailer
hitch and the tongue weight of
the loaded trailer) is limited.
The more passengers in the ve­
hicle or passengers who are
heavier than the standard
weights assumed mean that less weight can be carried as
luggage.
The tire pressure label on your
Audi also lists the maximum combined weight of all of the
occupants and luggage or other
cargo that the vehicle can carry.

Determining correct load
limit
Use the example below to cal­
culate the total weight of the
passengers and luggage or oth­
er things that you plan to trans­
port so that you can make sure
that your vehicle will not be overloaded.
Steps for Determining Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OC­
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS" on your ve­
hicle's placard (tire inflation
pressure label)
~ page 244,
fig. 195.
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 pas­
sengers from
"XXX" kilo­
grams or
"XXX" pounds
shown on the sticker
~ page 244, fig. 195.
4. The resulting figure equals
the available amount of car­
go and luggage load capaci­
ty. For example, if the
"XXX"
amount equals 1400 lbs.
and there will be five 150 lbs. passengers in your vehi­
cle, the amount of available
cargo and luggage load ca­
pacity is 650 lbs. (1400-750
(5
X 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo .,..

being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing
a trailer, load from your trail­
er will be transferred to your
vehicle. Consult this manual
to determine how this re­
duces the available cargo
and luggage load capacity of
your vehicle.

(¢ page 257, fig. 199) to de­
termine the designated load rating for a specific tire.
Tire service life
The service life of tires depends
on a lot of different things in­
cluding proper installation and
balancing, correct tire pressure and driving style.

Tread Wear Indicator (TWI)
The original tires on your vehi­
cle have
1/16 inch (1.6 mm)
high "wear indicators"
¢ fig. 197 running across the
tread. Depending on the make,
there will be six to eight of
them evenly placed around the
tire. Marks on the tire sidewall (for example "TWI" or other
symbols) indicate the positions
of the tread wear indicators.
Worn tires must be replaced.
Different figures may apply in
other countries
¢ & .
Tire pressure
Incorrect tire pressure causes
premature wear and can cause
sudden tire blow-out. For this
reason, tire pressure must be
checked at least once a month
¢ page 249.

272 What do I do no w?
• Always store the vehicle too l kit, the jack*
and the replaced tire in the luggage com­
partment
¢ page 132.
• Unhook the cargo floor before clos ing the
rear lid.
Using th e spare tir e (compac t spare tir e)
The compact spare tire is on ly intended for
emergencies until yo u can reach a repair shop.
Replace it as quickly as possible with a stand­
ard wheel and tire.
There are some restrictions on the use of the compact spare tire. The compact spare tire has been des igned specifically for your type of
vehicle. It must not be swapped with a com­ pact spare tire from another type of vehicle.
Sn ow chain s
For technical reasons, the use of snow chains
on the compact spare tire is
not permitt ed .
If you do have to dr ive with snow cha ins and a
front tire fails, mount the spare wheel with
tire instead of a rear tire . Install the snow
chains on the rear tire and use it to replace
the defective front tire.
A WARNING
- Never use the spare tire if it is damaged
or if it is worn down to the tread wear in­
dicators .
- If the spare tire is more than 6 years o ld,
use it only in an emergency and with ex­
t reme caution and careful driving .
- The spare tire is intended only for tem­
porary and short-term use. It should be
replaced as soon as possible w ith the
normal wheel and t ire.
- After mounting the compact spare tire,
the tire pressure must be checked as
soon as poss ible. The tire pressure of the
c ompact spare tire must be 4.2 bar; oth­
erwise, you risk hav ing an accident .
- Do not drive faster than 50 mph (80 km/
h). You risk having an acc iden t.
- Avoid full-throttle acce le rat ion, heavy
braking, and fast corner ing . You risk hav­
ing an a cc ident. -
Never drive using more than one spare
wheel and tire. You r isk having an acci­
dent.
- Normal summer or winter tires must not
be mounted on the compact spare wheel
rim.
- For technical reasons, the use of tire
chains on the spare tire is not permitted.
If it is necessary to drive with tire chains,
the spare wheel must be mounted on the
front ax le in the event of a flat in a rear
tire. The new ly available front wheel
m ust then be installed in place of the
rear whee l w ith the flat tire. Installing
the tire chain before mounting the whee l
and tire is recommended.
- Loose items in the passenger compart ­
ment can cause serious personal injury
during hard braking or in an accident. Never store the inflatable spare tire or
jack and tools in the passenger compart­ ment.
