- 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 . Be ing trapped in a vehicle can
lead to serious persona l injury.
- Never let children p lay in or around the
vehicle .
- Never let passengers r ide in the luggage
compartment . Veh icle occupan ts must
always be proper ly restrained in one of
the vehicle's seating positions.
(D Tips
- Air circulation helps to reduce window
fogging . Sta le air escapes to the o utside
th rough vents in the trim pane l. Be su re
to keep these slots free and open.
- The tire pressure must correspond to the
load . The t ire pr essure is shown on the
tire p ressu re label. The tire pressure la
bel is loc ate d on the driver's s ide B-pi lla r.
The tire pressure label lists the recom
men ded cold t ire inflat ion pressu res for
the veh icle at its maximum capacity
weight and the tires that were on your
vehicle at the time it was manufact ured.
For recommended t ire pressures for nor
mal load conditions, please see chapter
Q page 251.
Tie-downs
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items .
Use the tie-downs to secure your cargo prop
erly ¢ page 145, Loading the luggage com
partment .
In a coll is ion, the laws of phys ics mean that
even smaller items that are loose in the vehi
cle will become heavy missiles that can cause se
rious injury. Items in t he vehi cle possess en
ergy which vary with vehicle speed and the
weight of t he item . Vehicle speed is the most
s ignificant factor.
F or example, in a frontal collision at a speed
of 30 mph (48 km/h), the forces acting on a 10 -lb (5 kg) object a re abo ut 20 times the
normal weight of the item. This means that
the weight of the item would sudden ly be
about 200 lbs . (90 kg) . You can imag ine the
injur ies that a 200 lbs . (90 kg) item fly ing
fr ee ly t hro ugh the passenger compa rtment
cou ld cause in a col lision like this.
_& WARNING
We ak, damaged or imprope r straps used
to secure items to tie-downs can fail dur
i ng hard braking or in a collision and cause
se rious pe rsonal injury.
-Always use s uita ble mo unt ing straps an d
p roperly secu re items to the tie-downs in
the l uggage compa rtment to he lp pre
vent items from shift ing or fly ing fo r
ward as dangerous missiles.
- When the rea r seat backrest is folded
down, a lways use suitable mounting
straps and properly secure items to the
tie-downs in the luggage compartment
to hel p prevent items from fly ing for
ward as dangerous missiles into the pas
senger compartment.
- Never attach a chi ld safety seat t ether

Reporting Safety
Defects
Applicable to U.S.A.
If yo u b eli eve that your vehi cle
has a def ect whi ch could cau se
a crash or could cau se injury or
death, you should immediately
inform the National Highway
Traffic Safet y Administration ""
Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da
ta Recorder (EDR), installed by some manu
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re
corders".
Some state laws restrict the retr ieval or down
loading of data stored by EDR's that were in
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron
ic control modules for various vehicle systems
such as, for examp le, engine function, emis
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op
eration for diagnostic and repair purposes.
The recording capacity of the electronic con
trol modules is limited to data (no sound is re
corded) and only a small amount of data is ac
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip
ment.
Electronic Stabilization
Control (ESC)
Description
The Electronic Stabilization Control (ESC) rein
forces driver safety. It reduces the risk of slip
ping and improves driving stability. ESC de
tects critical s ituations such as the vehicle
Intelligent technology 197
oversteering and understeering or the whee ls
spinning . The vehicle is stabilized by applying
the brakes or reducing eng ine torque . Once
the ESC is active, the indicator light
G1 blinks
in the instrument cluster.
ESC includes the anti-lock brake system (ABS),
brake assist system, anti-slip regulation
(ASR), electronic differential lock (EDL), dy
namic steering*, hill descent assist and selec
tive wheel torque control.
Anti-lock brake system (ABS)
ABS prevents the whee ls from locking up
when braking . The vehicle can still be steered
even during hard braking. App ly steady pres
sure to the brake pedal. Do not pump the ped
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle .
Brake assist system
The brake assist system can decrease braking
distance. It increases braking power when the
driver presses the brake pedal quickly in emer
gency situations . You must press and hold the
brake pedal until the situation is over . In
vehicles with adaptive cruise control*, the
brake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels beg in to sp in and adapts the force to
the road conditions. This makes it easier to
start, accelerate and drive up hill s.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the othe r whee ls .
T his function is available up to about 78 mph
(125 km/h) .
In extreme cases, EDL automatically switches
off to help keep the brake on the braked wheel
from overheat ing. EDL will switch on again au
tomatically when conditions have returned to
normal.

- 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 tire 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. 205 Tire press ure label: 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
square 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 pressu re 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.
Therefo re, you shou ld neve r let air out of a
warm tire to ma tch "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,

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 3 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
vehicle equ ipment dur ing the model year, a l
ways compare the tire size designation on the
tire pressure labe l on you r veh icle w it h the
tires on your vehicle. Ma ke su re that the tire
size info rmation on the vehicle label is the
same as the size of the tires on the vehicle.
This is especia lly important if the vehicle be
longs to someone else or you bought the vehi- cle w
ith different rims/t ires or you bought the
vehicle as a prev iously owned vehicle.
Remember, your safety and that of your pas
sengers also depends on making sure that
load lim its are not exceeded. Vehicle load in
cludes eve rybody and everyth ing in and on the
vehicle. These load l imits a re techn ica lly refer
red to as the vehicle's Gross Vehicle Weight

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 B-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 label¢

.8, 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
trol 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 .
.8, 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.
Tires and wheels 253
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 251, 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 higher 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 251 . 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¢
page 251, fig. 205 .
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
used today are underinflated just by looking
at them.
Therefore, be sure to check tire pressures at
least once a month and always before going
on a long trip. Make sure to take the number
of people and the amount of luggage into ac
count when adjusting tire pressure for a trip -
even one that you would not consider to be
"long." See¢
page 255, Tires and vehicle
load limits
for more important information .
Always use an accurate tire pressure gauge
when checking and adjusting inflation pres
sures. Check all of the tires and be sure not to ..,. •
