& WARNING (continued )
• 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
c au sing lo ss of control and a cra sh.
• Always make sure that the total load being transported -
including the we ight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
v ehicle's Gross Vehicle Weight Rating .
& WARNING
• Incorrect tire pressures and /or underinflation can lead to a
serious or fatal accident.
• Incorre ct tire pressures and /or underinflation cause in creased
tire wear and can affect the handling of the vehicle .
• Incorrect tire pressures and /or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
c ausing loss of vehi cle control.

Checking tire pressure
The c orrect tire pressu re f or the tires ori gina lly installe d
on your vehicle is lis ted on the ti re pressure la bel loca ted
either on driver's side 8-pillar or inside the fuel filler flap.
The rec omme nded ti re p ressu res a re on the tire pr essure la be l an d
in the
table~ page 328, "Co ld tire inflation pressure". This means
t ha t th e pres su re m us t be c hecked a nd adjus ted w he n t he ti re has
not been driven for more than a couple of miles (kilometers) at low
speeds du rin g the p revio us th ree hou rs . Ai r in t he tires ex pand s
when the tire heats up as a resu lt of internal fr iction as it flexes in
use. The tire pressure is hig her when the tire has warmed up than
when it is "co ld ." I
t is the inflation pressure in a "cold" t ire that counts . Therefore, you
s h oul d never le t air ou t of a warm ti re to matc h "Co ld t ire in fl ati on
pressure"
recommendations~ pa ge 328 . The tires wou ld then be
u nde rinflate d and could fail sud denly .
The t ire pressure label o n your Au di lists the recomme nded cold t ire
inflation press ures at maximum capacity for the new, origina l equip ­
m ent tires t hat we re on yo ur vehicle at t he t ime it was manufac ­
tured. For the location of the
labe l~ page 328, fig . 272.
M ost tires lose a ir natu rally ove r ti m e. T hey can a lso lose so me air if
you drive ov er a pothole or h it a curb while parkin g. It is usually not
pos sible to see whe the r the rad ial tir es use d today are unde rin flated
just by look in g at t hem .
T herefore, be sure to chec k tire pressures at least once a month and
a lways be fore go ing o n a lo ng trip . Make su re to take the nu mber o f
people and the amount of luggage into account when ad justing tire
pr ess u re fo r a trip -even one t hat you wou ld not conside r to be
" long ."
See~ page 333, "Tires and vehic le load limits" for more
i mp ort ant i nfor mati on .
A lways use a n accu rate ti re p ressure gauge w hen c hec kin g a nd
adjusting inflation pressures . Chec k all of the tires and be sure not
t o fo rget t he spare t ire . If the pressu re i n an y tire is too high when
the tire is "co ld," let air out of the tire slow ly with the edge of the tire
ga uge and kee p checking the press ure u ntil y ou r each th e pr essu re
that is correct for the load (passengers and luggage) and kind of
d riv in g yo u plan to do .
I f the pressure in any tire is too low, note the difference between the
pressure in the cold tire and the pressure you need and add the air
t hat you need to r each the correct pressure for the veh ic le load
(passengers and luggage) for the tires on your vehicle as listed on
t he o n you r vehicl e and i n thi s m anua l a n d t he kind of driving yo u
p lan to do.
Never exceed the maximum inflation pressure listed on the tire
sidewall for any reason .
Remember that the vehic le manufacturer, not the tire manufacturer,
deter mines the correc t tire pressure for the ti res on your vehicle.

Driving without valve stem caps can cause damage to the tire
valves. To prevent this, a lways make sure that factory instal led valve
stem caps on a ll whee ls are securely mounted on the va lve .
W Fo r the sake of the env ironm ent
Underinflated tires wil l a lso increase the fuel consumption. •
Tires and vehicle load limits
There are lim its to t he amount of load or weight that any ve hicle and
any tire can carry . A vehicle that is overload ed wil l not hand le well
and is more difficu lt to stop. Overload ing can not only lead to loss
of vehic le control , but can a lso damage important parts of the
vehic le and ca n lead to sudden t ire fa ilure, inc luding a blowout a nd
sudden deflation that can cause the vehic le to crash.
Your safety and that of your passengers also depends on making
sure that load l imits are not exceeded. Vehicle load includes every­
body and everything in and on the vehic le. These load limits are
technica lly referred to as the vehicle's
Gross Ve hicle We ig ht R ating
("GVWR").
The "GVWR" includes t he weight of the bas ic ve hicle, al l factory
insta lled accessories, a full tank of fuel , oil , coolant and other fluids
p lus maximum load . The maximum load i ncludes the number of
passengers that the vehicle is intended to carry ("seating capacity")
with an assumed weight of 150 lbs (68 kg) for each passenger 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 h itch and the
tongue we ight of the loaded trai ler must be included as part of the
vehic le load.
The
Gros s Axle We ight Rating ("GAWR") is the maximum load t hat
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 comp liance s ticker label loca ted either on
the driver's side B-pillar or on the inside of the fuel fil ler flap . Your
Audi has 5 seating positions, 2 in the front and 3 in the rear for total
seating capacity of 5. Vehicles with power individual rear seats*
have 4 seating positions, 2 in the front and 2 in the rear for total
seating capacity of 4. Eac h seating position has a safety be lt
~ page 209, "Safety be lts".
The fact that there is an upper limit to your veh icle's Gross Vehicle
Weight Rating means that the total weight of whatever is being
carried in the veh ic le ( including t he we ight of a trai ler hitch and the
tongue weight of the loaded trai ler) is limited . The more passengers
in the vehicle or passengers who are heavier than the standa rd
we ights assumed mean that less weight can be carried as luggage .
The tire pressure labe l on your Audi also lists the maximum
combined we ight of a ll of the occupants and luggage or other cargo
that th e vehicle can carry. For the location of the lab el
~ page 328 ,
fig. 272 .
& WARNING
Overloading a v ehicl e can cau se loss of vehicl e control , a cras h or
o ther ac cident , serious p ers on al injur y, and eve n de ath.
• C arrying more weight th an your vehi cle was designed to c arry
will prevent the vehicl e from handling prop erl y and in cre a se the

Vehicle care

-Tires and wheels Determining correct load limit
Use the example below to calculate the
total weight of the passengers and
luggage or other things that you plan to
transport 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 OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard (tire infla­
tion pressure label) => page 328, fig. 272.
2. Determine the combined weight of the driver and passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from
"XXX" kilo­
grams or
"XXX" pounds shown on the
sticker=> page 328, fig. 272. 4. The resulting figure equals the available
amount of cargo and luggage load
capacity. For example, 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 load capacity 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 trailer will be transferred
to your vehicle. Consult this manual to
determine how this reduces the avail­
able cargo and luggage load capacity of
your vehicle.
- Check the tire sidewall
( => page 336,
fig. 276) to determine the designated
load rating for a specific tire. •
