area because the rear lid cannot be fully
closed.
- If you absolutely must drive with the rear
lid open, observe the following notes to
reduce the risk of poisoning:
- Close all windows,
- Close the power top,
- Open all air outlets in the instrument
panel,
- Switch off the air recirculation,
- Set the fresh air fan to the highest
speed.
A WARNING
Always make sure that the doors, all win­
dows, the power top and the rear lid are
securely closed and locked to reduce the
risk of injury when the vehicle is not being
used .
-After closing the rear lid, always make
sure that it is properly closed and locked .
- Never leave your vehicle unattended es ­
pecially with the rear lid left open. A
child could crawl into the vehicle through
the luggage compartment and close the
rear lid becoming trapped and unable to
get out. Being trapped in a vehicle can
lead to serious personal injury.
- Never let children play in or around the
vehicle.
- Never let passengers ride in the luggage
compartment. Vehicle occupants must
always be properly restrained in one of
the vehicle's seating positions.
(D Tips
- Air circulation helps to reduce window
fogging. Stale air escapes to the outside
through vents in the trim panel. Be sure
to keep these slots free and open.
- The tire pressure must correspond to the
load. The tire pressure is shown on the
tire pressure label. The tire pressure la­
bel is located on the driver's side B-pillar.

Tie-downs
Applies to vehicles: with tie-downs
The luggage compartment is equipped with
four tie-downs to secure luggage and o ther
items.
Use the tie-downs to secure your cargo prop­
erly
r::::> page 12 7, Loading the luggage com­
par tmen t.
In a collision, the laws of physics mean that
even smaller items that are loose in the vehi­
cle will become heavy missiles that can cause
serious injury. Items in the vehicle possess en­
ergy which vary with vehicle speed and the
weight of the item . Vehicle speed is the most
significant factor.
For example, in a frontal collision at a speed
of 30 mph (48 km/h), the forces acting on a 10-lb (4 .S kg) object are about 20 times the
normal weight of the item . This means that
the weight of the item would suddenly be about 200 lbs. (90 kg). You can imagine the
injuries that a 200 lbs. (90 kg) item flying
freely through the passenger compartment could cause in a collision like this.
A WARNING
Weak, damaged or improper straps used
to secure items to tie-downs can fail dur­ ing hard braking or in a collision and cause
serious personal injury.
- Always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help pre­
vent items from shifting or flying for­
ward as dangerous missiles.
- When the rear seat backrest is folded
down, always use suitable mounting
straps and properly secure items to the
tie-downs in the luggage compartment
to help prevent items from flying

228 Tire s and wheel s
-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age.

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.
Fig. 182 Tir e pressure labe l: located on driver 's s ide B·
p ill ar
Tire pressure generally refers to the amount
of air in a tire that it needs it to do its job and
safely carry the combined load of the entire
vehicle and its contents . Tire pressure is
measured in kilopasca ls (kPa), the interna­
tional measuring unit and in pounds pe r
squa re inch (PSI). Tire pressure is based in
part on the vehicle's design and load limit -
the greatest amount of weight that the vehi­
cle can carry safe ly and the t ire size . The prop­
er tire pressure is frequent ly referred to as the
"recommended cold tire inflation pressure."
Air in the tires expands when the tire heats up
because of internal friction when it flexes in
use . The tire pressure is higher when the tire
has warmed up than when it is "cold ."
It is the
in flat ion pressure i n a "cold " tire that counts.
Therefore, you shou ld neve r let air out of a
warm tire to match "cold tire inflat ion pres­
sure" recommendations. The tires would then
be underinflated and could fail suddenly.
Maintaining proper tir e pressure is one of the
most impor tant things you can do to help
avoid sudden tire failure. Underinflated tires
are a ma jor cause of s udden tire failure . Keep­
ing tires at the right pressure is also impor­
tant for safe and responsive vehicle handling,

traction, braking and load carrying. Tire pres­
sures are particularly important when the
vehicle is being driven at higher speeds, and
then especially when heavily loaded even
within the permissible load-carrying capaci­
ties approved for your vehicle.
The recommended tire pressures for your Audi
depend on the kind of tires on your ve hicle
and the number of passengers and/o r amount
of luggage you w ill be transporti ng.
The tire pressure label is located on the driv­
er's side B -pillar . The tire pressure labe l lists
the recommended cold tire inflat io n pressures
for the vehicle at its maximum capacity
weight and tires that were on your veh icle at
t he time it was manufactured.
If you wish to improve comfort when operat­
ing the vehicle at normal load (up to 2 occu­
pants), you can adjust tire pressures to those
specified for normal vehicle load. Before op­
erating the vehicle at maximum load, you
must increase the tire pressures to those
specified for maximum vehicle load

Because technical changes may be made to
ve hicle equipment during the model year, al­
ways compare the tire size designation on the
tire pressure labe l on your vehicle w ith the
tires on your vehicle. Make sure that the tire
size information on the veh icle label is the
same as the size of the tires on the vehicle.
This is especially important if the vehicle be­
lo ngs to someone else or you bought the veh i- 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
l oad lim its are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
vehicle. These load limits are techn ically refer­
red to as the veh icle's Gross Vehicle Weight
Rating ("GVWR"). The Gross Axle Weight Rat­
ing ("GAWR") is the maximum load that can
be applied at eac h of the vehicle's two axles .
T he Gross Vehicle Weight Rating and the .,.

Gross Axle Weight Rating are listed on the
safety compliance sticker label located on the
driver's side B-pi llar . The tire pressure label on
your Aud i lists the maximum combined
weight of all of the occupants and luggage or
other cargo that the vehicle can carry . For the
locat io n of the tire pressure label¢

A WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a cras h or other accident, se­
r ious personal inj ury, and eve n death.
- Carry ing more weight than yo ur vehicle
was designed to ca rry will p revent the
vehicle from hand ling properly and in­
crease the risk of a loss of veh icle con ­
t ro l.
- T he bra kes on a veh icle that has bee n
overloaded may no t be a ble to stop the
vehicle within a safe distance .
- T ires 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 tota l load be ­
ing transported - including the weight of
a trai le r hitch and the tongue weight of a
loaded trailer -does not make the veh i­
cle heav ier than the veh icle's Gross Vehi­
cle Weight Rating .
A WARNING
- Incorrect tire pressures and/or underin­
flation can lead to a serious o r fatal acci­
dent .
- Incorrect tire pressures and/or underin­
flation cause increased tire wea r and can
affect the handli ng of the vehicle.
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fa il­
ure, including a blowo ut and sudde n de­
fla tion, 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
ti re pressu re label and in the table
¢ page 231, Cold tire inflation pressure.This
mea ns tha t the pressu re m ust be chec ked and
adjus ted when the t ire has not been dr iven fo r
more than a couple of miles (kilometers) a t
low speeds d uring the previous three ho urs.
Air in the tires expands when the tire heats up
as a result of interna l frict ion as it flexes in
u se. The tire pressure is higher when the tire
has warmed up than whe n it is "cold ."
It is the inflation pressure in a "co ld" t ire that
counts. Therefore, you should never let a ir o ut
of a warm tire to match "Cold t ire inflat ion
pressure" recomme ndat io ns¢
page 231 . The
ti res wou ld then be unde rinflated and could
fail suddenly .
The t ire pressure label on your Audi lists the
recommended co ld tire inflation pressures at
max imum capac ity for the new, orig inal
equipment tires that were on your ve hicle at
the time it was ma nufactu red. For the lo ca­
t ion of the labe l

Most tires lose air natura lly ove r time . They
can a lso lose some air if you d rive over a pot­
hole or hit a curb while par king.
It is usually

-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 KG OR XXX LBS"on your vehi­
cle's placard (tire inflation pressure label)
¢fig. 182.
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" kilo­
grams or
"XXX" pounds
shown on the sticker
¢fig. 182.
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
vehicle. Consult this manual
to determine how this re­ duces the available cargo

Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed rims. If differen t rims are fit­
ted, the correct wheel bolts with the r ight
length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
secure ly and that the brake system funct ions
correctly .
In ce rtain circumstances, you may not use
wheel bolts from a different vehicle -even if it
i s the same model~
page 2 71.
_& WARNING
Improperly tig htened o r maintained whee l
bolts can become loose ca using loss of
contro l, a co llision and serious persona l in­
jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­
erly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can
become loose while driving if greased or
oiled, even if tightened to the specif ied
torque .
- Only use wheel bolts that belong to the
rim being installed .
- Never use different wheels bolts on your
vehicle .
-Always maintain the correct tighten ing
torque for the wheel bo lts to reduce the
risk of a wheel loss. If the tightening tor ­
que of the wheel bolts is too low, they
can loosen and com e out when the veh i­
cl e is moving. If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be­
come loose.

Low aspect ratio tires
Your Audi is factory -equ ipped w ith low aspect
ratio tires . T hese tires have been thoroughly
tested and been se lected specifically fo r your
model for their superb perfo rmance, road fee l
and hand ling under a variety o f driv ing condi ­
t ions . As k your authorized A udi dealer for
more details .
T he low aspect ratio of these tires is ind icated
by a numera l of
55 or l ess in the tire's s ize
designation. The numeral represents the ratio
of the tire's sidewa ll height in relation to its
tread width exp ressed in percentage . Conven­
tiona l tires have a he ight/w idth ratio of 60 or
more .
The performance of low-a spect-r atio tire s is
pa rt icul arly s ens itive to imp ro per i nfl ation
pressure. It is therefore import ant that low
aspect ratio tires are inflated to the specified pre ssure and that the inflation pressure is
r e gularly checked and maintained . Tire pres­
sur es should be checked at l east once a
month and always before a long trip
~ page 233, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w it h potholes, c urbs, g ull ies
o r ridges on the road, pa rticul arly if the tire is
u nderinfla ted .
In orde r to minimize the occurrence of impact
damage to t he tires of your vehi cle, we recom­
mend tha t you observe the following preca u­
tions:
- Always ma inta in recommended inflation
pressu res. Check your tire pressure eve ry
2 ,000 miles (3,000 km) and add air if neces -
sary. ..,.

-Drive carefully on roads with potholes, deep
gullies or ridges. The impact from driving
thro ugh or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Aud i dealer. Replace a damaged
t ire as soon as possible .
- Inspect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see . Damage can lead to loss of
air and underinflation, wh ich could eventu­
ally cause ti re fail ure. If you be lieve that a

Reduced performance in winter /cold
season condit ions
All t ires are des igned for certa in pu rposes.
The low aspect ratio, ultra high pe rformance
tires originally installed o n your vehicle are in­
tended for max imum dry and wet road per­
formance and handling . They are not suitable
for cold, snowy or icy weather condit ions. If
you dr ive under those circumstances, you
should equip your veh icle with all-season or
winter t ires, which offer better traction under
those cond itions . We suggest you use the re c­
ommended snow or all-season tires specified
for your ve hicl e, or their equ ivalent .

Tire pressure
monitoring system
U) General notes
Ap plies to vehicles: with tire pressure monitoring system
Each t ire , includ ing the spare (if provided),
should be che cked mo nth ly when cold and in-
Tire s an d wheel s 245
flated to the inflation pressure recommended
by the vehicle man ufact urer on the vehicle
placard or tire inflat ion pressure labe l. (If your
vehicle has tires of a different size than the
s ize indicated o n the vehicle placard or tire in­
flat ion pressure labe l, you shou ld determine
the proper t ire inflation pressu re for those
tires) .
As an added safety feature, your veh icle has
been equipped with a tire pressure monitoring
system ( TPMS) that illum inates a low tire
pr essure te lltale when one o r more of you r
tir es is s ignificant ly unde r-inflated. Acco rding ­
ly, when the low tire pressure tell tale illumi­
nates, you shou ld stop and check you r tires as
soon as possib le, and inflate them to the
proper pressure . Driving on a significant ly un­
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure. Under-inflation al­
so reduces fuel effic iency and tire tread life,
and may affect the vehicle's hand ling and
stopp ing abil ity .
Please note that the TPMS is not a substit ute
for proper tire ma intenance, and it is the driv­
er 's respons ibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to tr igger illuminat ion of the
T PMS low ti re p ressu re tellta le.
Your vehicle has also been equipped with a
T PMS ma lfunction ind icator to ind icate when
the system is not operating p rope rly . T he
T PMS ma lfun ction indicator is comb ined w ith
the low tire pressure te lltale . Whe n the sys ­
tem detects a malfunc tion, the telltale will
flash for approximate ly one mi nute and then
remain continuously i lluminated. T his se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunct ion exists .
When the malfunction indicato r is illum inat­
ed, the system may not be ab le to detect or
s ignal low tire pressure as intended. TPMS
malfu nctions may occur for a var iety of rea­
sons, including the installation of replace­
ment or a lternate tires or wheels on the vehi ­
cle that p revent the TPMS from functioning
properly. Always check the TPMS malfunction
t e llt ale after rep laci ng one or more tires o r ..,.
