2013 AUDI S7 trailer

212 Trailertowing
If you move the selector lever of the auto­
mat ic transm ission to P before app lying
the park ing brake and before blocking the
wheels, you may have to use mo re force
later to move the lever out of the P posi­
tion .

252 Tires and wheels
This is especia lly important if the vehicle be­
longs to someone else or you bought the vehi­
cle with different rims/tires or you bought the
vehicle as a previously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on making sure that
load limits are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
vehicle. These load limits are technically refer­
red to as the vehicle's Gross Vehicle Weight
Rating (' 'GVWR"). The Gross Axle Weight Rat­
ing ("GAWR") is the maximum load that can
be applied 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 sticker label located on the
driver's side 8-pillar. The tire pressure label on
your Audi lists the maximum combined
weight of all of the occupants and luggage or
other cargo that the vehicle can carry. For the
location of the tire pressure labe l
¢fig . 196.
A WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more weight than your vehicle
was designed to carry will prevent the
vehicle from handling properly and in­ crease the risk of a loss of vehicle con­
trol.
- 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 overload­
ed can fail suddenly causing loss of con­
tro l and a crash.
- Always make sure that the total load be­
ing transported -including the weight of
a trailer hitch and the tongue weight of a
loaded trailer - does not make the vehi­
cle heavier than the vehicle's Gross Vehi­
cle Weight Rating.
A WARNING
- Incorrect tire pressures and/or underin­
flation can lead to a serious or fatal acci­
dent.
- Incorrect tire pressures and/or underin­
flation cause increased tire wear and can affect the handling of the vehicle.
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fail­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
Checking tire pressure
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressure label located on driver's side 8-pil­ lar.
The recommended tire pressures are on the
tire pressure label and in the table
¢ page 250, Cold tire inflation pressure.This
means that the pressure must be checked and
adjusted when the tire has not been driven for
more than a couple of miles (kilometers) at
low speeds during the previous three hours.
Air in the tires expands when the tire heats up
as a result of internal friction as it flexes in
use. The tire pressure is highe r when the tire
has warmed up than when it is "cold ."
It is the inflation pressure in a "cold" tire that
counts. Therefore, you should never let air out
of a warm tire to match "Cold tire inflation
pressure" recommendations¢
page 250. The
tires would then be underinflated and could
fail suddenly.
The tire pressure label on your Audi lists the
recommended cold tire inflation pressures at
maximum capacity for the new, original
equipment tires that were on your vehicle at
the time it was manufactured. For the loca­
tion of the label¢
fig. 196.
Most tires lose air naturally over time . They
can also lose some air if you drive over a pot­
hole or hit a curb while parking. It is usually
not possible to see whether the radial tires ..,.

the vehicle can carry. For the location of the
label
~ fig. 196.
A WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more weight than your vehicle was designed to carry will prevent the
vehicle from handling properly and in­
crease the risk of the loss of vehicle con ­
trol.
- 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 overload ­
ed can fail suddenly, including a blowout
and sudden deflation, causing loss of
control and a crash.
- Always make sure that the total load be­
ing transported -including the weight of
a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehi­
cle heavier than the vehicle's Gross Vehi­
cle Weight Rating.
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
Tires and wheels 255
KG OR XXX LBS" on your ve­
hicle's placard (tire inflation
pressure label)
¢ fig. 196.
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
¢ fig. 196.
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. (1400-7 SO
(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
vehi cle. Consult thi s manual
to determine how this re­
duces the available car go
and luggage lo ad capacity of
yo ur vehicle .
.,. Check the tire sidewall
(9 fig . 200 ) to de termine the
de signated load rating for a
s pe cifi c tir e.
Tire service life
The s ervi ce life of tires dep ends on a lot of
different things including proper installation
and balancing, correc t tire pressu re and driv­
ing style.

ing on the make, t here will be six to eight of
them even ly placed aro und the tire. Marks on
the tire sidewall (for examp le "TWI" or other
symbols) ind icate the positions of the tread
wear indicato rs . Wor n tires must be rep laced.
D iffere nt f igures may apply in othe r countr ies
Q ,&. .
Tire pressure
Incorrect t ire pressure ca uses premature wear
and can cause sudde n tire blow-out. For this
reason, tire pressure must be checked at least
o nce a month ¢
page 2 52.
Driving style
Driving fast around c urves, heavy acce lerat ion
and hard braking increase tire wear .
Rotating tires for more even wear
Fo r all four tires on your ve hicle to have the
same service life, we recommend that the
front and rear t ires a re rotated according to
the tire manu fact urer's suggested tire rota­
tion intervals. Please remember the follow­
ing :
- Tire rotation intervals may differ from t he
veh icle service interva ls outlined in your
Warranty
& M aintenance booklet.
- The longer one tire is used in one location
o n t he vehicle, the more it wears at certain
points; theref ore, we recommend t hat y ou
follow the tire manufacturer's suggested
tire rotation int ervals .
- Veh icles w ith front-wheel dr ive experience
more tread wear on the fro nt wheels com­
pa red to a ll-wheel drive ( quattro ®).
- Please rotate tires as shown¢
fig. 199.
- Extra care must be taken when rotating di-
rection-specific tires ¢
page 274.
Wheel balancing
The wheels on new ve hicles are balance d.
Howeve r, various s ituations during everyday
dr iv ing can cause them to become unba l­
anced, resulti ng in vibrations you can usually
feel th rough the steer ing wheel.
