A WARNING ,~
Heavy loads will influence the way your ve­
hicle handles. To help reduce the r isk of a
loss of control leading to ser ious personal
injury:
-Always keep in m ind when transporting
heavy objects, that a change in the cen­
ter of g ravity can also cause changes in
vehicle handling:
- Always distribute the load as even ly as
possible.
- Place heavy objects as far forward in
the luggage compartment as possible.
- Never exceed the Gross Ax le Weight Rat­
ing or the Gross Vehicle Weight Rating
specified on the safety compliance stick­
er on the left door jamb. Exceeding per­ missible we ight standards can cause the
vehicle to slide and handle differently .
- Please observe information on safe driv­
ing
i:> page 90.
A WARNING
To help prevent poisonous exhaust gas
from be ing drawn into the veh icle, always
keep the rear lid closed while dr iving.
- Never transport objects larger than those fitting completely into the luggage
area because the rear lid cannot be fully
cl osed.
- If you absolutely must drive with the rear
lid open, observe the follow ing notes to
reduce the risk of poisoning:
- Close all windows,
- Open all air outlets in the instrument
panel,
- Sw itch off the air recircu lation,
- Set the fresh ai r fan to the h ighes t
speed .
A WARNING
Always make sure that the doors, all win­
dows and the rear lid are securely closed
and locked to reduce the risk of injury
when the veh icle is not being used.
Dr iving S afel y 97
-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 o ut. Being trapped in a vehicle can
lead to serious personal injury.
- Never let ch ildren play i n or around the
veh icle .
- Never let passengers ride in the luggage
compartment. Vehicle occupants must
always be prope rly restra ined in one of
the vehicle 's seating pos it ions .
(D Tips
- Air circulation helps to reduce window
fogging. Stale a ir escapes to the outside
through vents in the trim panel, on the
left side of the luggage compartment. Be sure to keep these s lots free and
open.
- The tire pressure m ust 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.
The tire pressure label lists the recom­
mended co ld tire inflation pressures for
the vehicle at its maximum capacity
we ight and the tires that were on your
vehicle at the t ime it was manufactured .
For recommended tire pressures for nor­
ma l load cond itions, please see chapter
i=>page 200.
Tie-downs
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items.
Use the t ie-downs to secure your cargo prop­
erly
c> page 96, Loading the luggage com­
partment .
In a collision, the laws of physics mean that
even smaller items that are loose in the vehi-
cle w ill become heavy missiles that can cause .,.

@ For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate
Material -special handling may apply, see
www.dtsc.ca .gov/hazardouswaste/per­
chlorate. When the vehicle or parts of the
restraint system including airbag modules
and safety belts with pretensioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authorized
Audi dealer is familiar with these require­
ments and we recommend that you have
your dealer perform this service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control
unit. Some suspension changes can, for exam­
ple, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in which it would not deploy if the
changes had not been made. Other kinds of
changes may reduce the force levels meas ­
ured by the sensors and prevent the airbag
from deploying when it should.
The sensors in the safety belt buckle for the
driver and front passenger seat tell the elec­
tronic control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high­
er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular collision, it is possible that an airbag
will not deploy at a seating position where the safety belt is being used but will inflate at the
position where the safety belt is not being
used. It is important that nothing interfere
with the safety belt buckles so that the sen-
Airbag system 123
sors can send the correct information about
safety belt use to the electronic control unit.
A WARNING
Changing the vehicle's suspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
formance and increase the risk of serious personal injury in a crash.
- Never install suspension components
that do not have the same performance characteristics as the components origi­
nally installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
A WARNING
-
Items stored between the safety belt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the electronic con­
trol module and prevent the Advanced Air­
bag System from working properly.
- Always make sure that nothing can inter­ fere with the safety belt buckles and that
they are not obstructed.
Knee airbags
Description of knee a irbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants.

Automatic car wash
The vehicle can be washed in almost any
modern automatic car wash .
The vehicle paint is so durable that the vehicle
can normally be washed without problems in
an automatic car wash. However, the effect on
the paint depends to a large extent on the de­
sig n of the fac ility, the filtering of the wash
water, the type of wash and care mater ial , etc.
If the paint has a dull appearance afte r go ing
through the car wash or is scratched, bring
this to the attention of the operator immedi­
ately. If necessary, use a different car wash.
Before going through a ca r wash, be s ure to
take the usual precautions such as closing the
windows. Remove antenna if applicable .
If you have installed additional accessories on
the vehicle -such as spoilers, e tc. -it is best to
ask the car wash operator i f these should be
removed .
A WARNING
Always read and heed all WARNINGS and
the information ¢
page 164.
(D Note
- Fold the exterior mirrors -flat the re is a
risk of damaging the exterio r mirrors .
Power folding exterior mi rrors must not
be fo lded in or out by hand. Use the pow­
er function!
- Compare the track of your vehicle w ith
the d istance between the guide ra ils of
the facility- there is a risk of damage to
the wheels and tires .
- Compare the width of your vehicle wit h
the width of the tu nnel at the fac ility.
Washing the vehicle by hand
A lot of water is needed when washing a vehi­
cle by hand.
~ Befo re you start washing, make sure you
have read and understood the WARNINGS
¢ A in General informa tion on page 164 .
Cleaning and protec tion 165
~ First soak all dried d irt unt il it is soft, then
rinse it off.
~ As you clean yo ur vehicle, start w it h the
roof and work your way down to the bottom,
using a sponge, a sponge g love or a clean
brush .
~ Rinse the sponge o r the sponge glove often,
flushi ng it clean each time.
~ Use spec ia l car shampoo only fo r very per­
sisten t dirt.
~ Rinse the car thoroughly wit h water.
~ Use a chamois leather to gent ly wipe the ex -
terior dry .
U se a separate sponge for cleaning the
whee ls, door s ills and other regions exposed
to road dirt. In this way, yo u wi ll not scratch
the paint wit h coarse particles imbedded in
the sponge the next time you wash the car.
A WARNING
- Wash your vehicle only when the ignition
is switched off to reduce the risk of a
crash .
- Always read and heed all WARNINGS and
other information ¢
page 164.
(D Note
-Never try to remove dirt, mud or dust if
the surface of the veh icle is dry. Never
use a dry cloth or sponge, s ince this
cou ld scratch your vehicle's paint or win­
dows .
- Never wash your car in bright sun light.
Drops of wate r act as mag nifying lenses
and may damage yo ur paint .
- Whe n you wash your car in the winter: if
you rinse yo ur vehicle with a hose, be
c ar efu l not to aim the stream of water
directly at locks, or at doo r or hatch
openi ngs -they can free ze sh ut.
- Never use sponges designed to
remove
insec ts, or any k itche n sco uring sponges
or s imil ar p rod ucts. They can damage
your paint finish .
- Never use a dry cloth or sponge to clean
the headlights . Only use wet cloths o r
•
•

-Never mount used tires on yo ur vehicle if
yo u 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 tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, 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 , p erformance and safe ty of a vehicle.
Fi g. 14 2 T ire p ress ure la b el: loca ted on driver's side B·
p ill ar
Tire pressure genera lly refers to the amount
of air in a t ire 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 i nterna·
tional measur ing unit and in pou nds pe r
squa re inc h (PSI). Tire pressure is based in
par t on the vehicle's desig n and load limit -
the greatest amoun t of weight that the vehi·
cle can carry safe ly and the t ire size . The prop·
er tire pressure is freq uently referred to as the
" recommended cold tire inf lation pressure."
A ir in the tires expands when the tire heats up
because of internal frict ion when it flexes in
use . The t ire p ressu re is higher when the tire
h as wa rmed up tha n when it is "cold ." It is the
in flat io n pressu re i n a "cold" tire that counts.
Th erefore, you shou ld neve r let air ou t of a
warm tire to match " co ld tire inflat ion pres­
sure" recommendations . The t ires wo uld then
be underinflated and could fail su ddenly .
M ain taining p roper t ire pr essu re is one of the
most im po rt an t th ings you ca n d o to he lp
avoid sudden tire failure. Underin fla ted t ires
a re a ma jo r cause of s udden tire failure. Keep·
i n g tires at the right pressure is also impor­
tant for safe and responsive vehicle handling,

Because technical changes may be made to
ve hicle equipment during the model year, a l­
ways compare the tire size designation on the tire press
ure label on your vehicle with the
tires on your vehicle. Make sure that the tire

same as the size of the tires on the veh icle .
This is especially important if the vehicle be-

vehicle with diffe rent rims/ti res or you bought
the vehicle as a previously owned vehicle.
Remembe r, your safety and that of your pas­
sengers also depends on mak ing sure that
l oad limits are not exceeded . Vehicle load in­
cludes everybody and everything in and on the
ve hicle . 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 veh icle 's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rat ing a re listed on the
safety compliance st icker labe l located on the
d river's side B-pi llar. T he tire pressure label on
your Audi lists the maximum combined weight of a ll of the occupants and luggage or
othe r cargo that the vehicle can carry. For the
locat ion of the tire pressure label¢
fig. 142.
A WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
r ious personal injury, and even death.
- Carry ing more weight than your vehicle
was designed to carry will prevent the
vehicle from handling p roperly and in­
c rease the risk of a loss of veh icle con­
tro l.
- T he brakes on a veh icle that has been
overloaded may not be ab le to stop the
vehicle within a sa fe distance.
- Ti res on a vehicle that has been overload­
ed can fail suddenly causing loss of con­
tro l and a crash .
A WARNING
-Incorre ct 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 wear and can affect the handling of the vehicle .
- Incorrect tire pressures and/o r underin­
flation can also lead to sudden tire fai l­
ure, incl uding a blowo ut 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
t ire pressure label and in the table
¢
page 200, Cold tire inflation pressure. This
means tha t the pressu re must be che cked and
adjus ted whe n the t ire has not been dr iven fo r
more than a couple of miles (kilometers) at
l ow speeds d uring the previous t hree ho urs.
Air in the tires expands when the tire heats up
as a result of interna l friction as it flexes in
use. The tire pressure is higher when the tire
has warmed up than when it is "cold."
It is the inflation pressure in a "co ld" tire that
counts. Therefore, you should never let air out
of a warm tire to match "Cold tire inflat ion
pressure" recommendat ions ¢
page 200 . The
t ires would then be unde rinflated and could
fail suddenly .
The tire pressure label on your Audi lists the
recommended co ld tire inflation pressures fo r
the new, orig inal equ ipment tires that were
on your veh icle at the time it was manufac­
tu red. Fo r the location of the labe l

Most t ires lose air naturally over t ime . They
can a lso lose some air if you d rive over a pot­
hole or hit a curb while park ing. It is usually
not poss ible to see whethe r the rad ial tires
u sed today are underinfla ted just by loo king
at them .
T he refore, be sure to check t ire p ressu res at
least on ce a mo nth and a lways befo re going
on a long trip. Ma ke s ure to ta ke the n umbe r
of peop le and the amount of luggage into ac ­
count when adjusting tire pressure for a trip -
even one that yo u wo uld not consider to be
"long." See ¢
page 204, Tires and vehicle
load limits
for more important information.
Always use an accurate tire press ure ga uge
when checking and ad justing inflation pres­
s u res. Check all of the tires and be sure not to ..,.
