(D Tips
Always replace child restraints that were
installed in a vehicle during a crash. Dam­
age to a child restraint that is not visible
could cause it to fail in another collision
situation.
Advanced front airbag system and children
Your vehicle is equipped with a front "Ad­
vanced Airbag System" in compliance with United States Federal Motor Vehicle Safety
Standard (FMVSS) 208 as applicable at the
time your vehicle was manufactured .
T he Advanced Airbag system in your vehicle
has been certified to meet the "low-risk" re­
quirements for 3-and 6-year old children on
the passenger side and small adults on the
driver side. The low risk deployment criteria
are intended to reduce the risk of injury
through interaction with the airbag that can
occur, for example , by being too close to the
steering wheel and instrument panel when
the airbag inflates . In addition, the system
has been certified to comply with the "sup­
pression" requirements of the Safety Stand­
ard, to turn off the front airbag for infants up
to 12 months who are restrained on the front passenger seat in child restraints that are list­
ed in the Standard .
Even though your vehicle is equipped with an
Advanced Airbag system, all children, espe­
cially those 12 years and younger, should al­
ways ride in the back seat properly restrained
for their age and size. The airbag on the pas­
senger side makes the front seat a potentially
dangerous place for a child to ride. The front
seat is not the safest place fo r a child in a for­
ward-facing child safety seat. It can be a very
Child Safety 173
dangerous place for an infant or a larger child
in a rearward-facing seat.
The vehicle's Advanced Airbag System has a
capacitive passenger detection system in the
front passenger seat cushion that can detect
the presence of a baby or a child in a child re­
straint system on this seat.
The capacitive passenger detection system
registers the changes that result in an electri ­
cal field when a child, a child restraint, and a
baby blanket are on the front passenger seat .
The change in the measured capacitance due
to the presence of a child, a child restraint,
and a baby blanket on the front passenger
seat is related to the child restraint system resting on the seat . The measured capacitance
of a child restraint system varies depending
on the type of system and specific make and
model.
The electrical capacitance of the various
types, makes, and models of child restraints
specified by the U.S.National Highway Traffic
Safety Administration (NH TSA) in the relevant
safety standard are stored in the Advanced
Airbag System control unit together with the capacitances typical of infants and a 1-year
old child. When a child restraint is used on the
front passenger seat with a typical 1 year-old infant, the Advanced Airbag System compares
the capacitance measured by the capacitive passenger detection system with the data
stored in the electronic control unit.
Child restraints and Advanced front
airbag system
Regardless of the child restraint that you use,
make sure that it has been certified to meet
United States Federal Motor Vehicle Safety
Standards and has been certified by its manu­
facturer for use with an airbag. Always be sure
that the child restraint is properly installed at
one of the rear seating positions. If in excep­
tional circumstances you must use it on the
front passenger seat, ca refully read all of the
information on child safety and Advanced Air-
bags and heed all of the applicable ..,.

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of veh icle control. It works
only when the eng ine is running. ESC detects
certain difficult driv ing s ituations, including
when the vehicle is beginning to spin (yaw) out of cont ro l and helps you to get the vehicle
back under control by select ively brak ing the
wheels, and/or red ucing engine powe r and
p roviding steering assistance to help hold the
ve hicle on the driver's intended course . The in­
dicator light
m in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
phys ics. It will not a lways be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
h elp you master situat ions where there is a
sudden change in the coefficient of fr iction of
the road surface. When there is a sect io n of
d ry road that is s udden ly cove red with water,
slush o r snow, ESC canno t perform the same
way it would on the dry su rface.
If the vehicle

stead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because con-
Int ellig ent technolog y 193
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
D uring fast corner ing, particular ly on wind ing
roads, ESC cannot always deal as effectively
with difficult dr iv ing s ituations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic and weather conditions . ESC can­
not override the vehicle's physical lim its, in­
crease the availab le tract ion, or keep a veh icle
o n the road if road departu re is a result of
driver ina ttent io n. Instead , ESC imp roves the
poss ibility of keep ing the vehicle under con­
trol and on the road during extreme maneu­
vers by using the driver's steering i nputs to
help keep the vehicle go ing in the intended di­
rect ion. If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC includes and/or works together with the
anti-lock brake system (ABS), brake ass ist sys­
tem, ant i-slip regu lation (ASR), electron ic dif­
ferential lock (EDL), dynam ic steer ing* and
El ectronic interax le differentia l lock* /selective

the time. In ce rtain sit uat io ns when yo u need
less traction, you can sw itch off ASR by press­
ing the b utton
[fil ¢ page 195, fig. 178. Be
s u re to switch ASR on again when you no lon­
ger need less traction .
Anti-lock braking system (ABS )
ABS prevents the whee ls from locki ng up
when b raking. The vehicle can st ill be stee red
even during hard braking . App ly steady pres­
su re to the brake peda l. Do not pump the ped­
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle.
Brake a ssis t sy ste m
The brake ass ist system can decrease braking
distance . It increases braking power when the
driver presses the brake peda l quickly in emer­
gency s ituations. You must press and hold the
brake pedal unti l the situation is over. In .,,.

Always apply brakes early. When driving
downhill, shift into a lower gear to use the en­
g ine braking effect to slow the vehicle . Use of
the brakes a lone can cause them to overheat
and fail.
Air suspension*
When driving with a trai ler, activate the trailer
mode of the air suspension. Switch the air
suspension trailer mode on when you are tow­
ing a trailer. This will limit the regulation by
the air suspension while driving. Select in the
MMI:

towing > On .
Coolant temperature
The coolant temperature gauge¢ page 11
must be observed carefully. The coolant tem­
perature can increase if you drive on long in­
clines in a low gear at high engine speeds . Re­
duce your speed immed iately if the LEDs in
the top pa rt of the display turn on.
For more information about indicator lights,

A WARNING
Anyone no t properly restrained in a mov­
ing veh icle is at a much greater ris k in an
accident . Never let anyone ride in your car
who is not properly wearing the restraints
provided by Audi .
Trailer towing tips
Important to know
Your vehicle handles differently when tow ing
a trailer because of the addit ional weight and
d ifferent weight distribution . Safety, perform­
ance and economy w ill greatly depend on how
carefully you load your trailer and operate
your rig.
Before you actually tow your trailer, practice
M N turning, stopping and backing up in an area 0
~ away from traffic. Keep practicing until you
~ have become comp lete ly fam iliar with the way 1.1'1 ,...., 1.1'1 ,....,
Trailer towing 207
your vehicle-trai ler combination behaves and
responds.
Backing up is difficult and requires practice .
Backing up with a trailer generally req uires
steering action opposite to that when backing
up your vehicle without a trai ler.
Maintain a greater distance between your ve­
hicle and the one in front of you. You will need
more room to stop. To compensate for the
trailer , you wi ll need a larger than normal
turning rad ius.
When passing, remember that you cannot ac­
ce lerate as fast as you norma lly would be­
cause of the added load. Make sure you have
enough room to pass . After passing, allow
plenty of room for your trailer before chang­
ing lanes again .
Avoid jerky starts, sharp turns or rapid lane changes.
(D Tips
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the extra load ¢
page 292.
Parking on a slope
Do not park on a slope with a trailer. If it can­
not be avoided, do so only after doing the fol­ lowing:
When parking:
.,. App ly the foot brake .
.,. Have someone p lace chocks under both the
vehicle and the trailer wheels.
.,. With chocks in place, slowly release the
brakes until the wheel chocks absorb the
load .
.,. Turn the wheels towards the curb.
.,. Apply the parking brake .
.,. Select the P selector lever posit ion.
When re starting after parking:
.,. App ly the foot brake.
.,. Start the engine.

-Always inflate tires to the
recommended and correct
tire pressure before driving
off .
-Driving with underinflated tires bend more, letting
them get too hot resulting
in tread separation, sudden
tire failure and loss of con­
trol.
-Excessive speed and/over­ loading can cause heat
build-up, sudden tire failure
and loss of control.
-If the tire pressure is too low or too high, the tires
will wear prematurely and the vehicle will not handle
well.
- If the tire is not flat and you
do not have to change a
wheel immediately, drive at
reduced speed to the near­
est service station to check
the tire pressure and add air
as required.
@ Note
Driving without valve stem
caps can cause damage to
the tire valves. To prevent
this, always make sure that
factory installed valve stem caps on all
wheels are secure­
ly mounted on the valve.
@) For the sake of the environment
Underinflated tires will also
increase the fuel consump­
tion.
Tires and vehicle load limits
There are limits to the amount of load or weight that any vehi­
cle and any tire can carry. Ave ­
hicle that is overloaded will not
handle well and is more diffi­
cult to stop. Overloading can not only lead to loss of vehicle
control, but can also damage
important parts of the vehicle
and can lead to sudden tire fail­
ure, including a blowout and
sudden deflation that can cause
the vehicle to crash.
Your safety and that of your
passengers also depends on
making sure that load limits are
not exceeded. Vehicle load in­
cludes everybody and every­
thing in and on the vehicle.
These load limits are technical­
ly referred to as the vehicle's

Tire pressure indicator appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
Fig. 200 Display : und erinflatio n warn ing
Fig. 201 Display: Syste m malfunction
Using the ABS sensors , the tire pressure moni­
toring system compares the tire tread circum­
ference and vibration characteristics of the in­
dividual tires.
If the pressure decreases in one
or more tires, this is indicated in the instru­
ment cluster with a warning symbol
[9] and a
message ¢
fig. 200.
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad­
justed (e. g. when switching between partial
and full load pressure) or after changing or re­
placing a tire on your vehicle¢

thereafter, immediately drive your vehicle to
an authorized Audi dealer or authorized repair
facility to have the malfunction corrected.
A WARNING
- If the tire pressure indicator appears in
the instrument cluster display, one or
more of your tires is significantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures. In­
flate the tire pressure to the proper pres ­
sure as indicated on the vehicle's tire
pressure label¢
page 244 . Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining the correct tire pressures. You must
check the tire pressures regularly. ..,

A WARNING 1=
You or your passengers could be injured
while changing a wheel if you do not fol­
low these safety precautions:
- If you have a flat tire, move a safe dis­
tance off the road. Turn off the engine,
turn the emergency flashers on and use
other warning devices to alert other mo­
torists.
- Make sure that passengers wait in a safe
place away from the vehicle and well
away from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the
jack, always fully set the parking brake
and block the wheel diagonally opposite
the wheel being changed. When one
front wheel is lifted off the ground, plac­
ing the Automatic Transmission in P
(Park) will
not prevent the vehicle from
moving.
- Before you change a wheel, be sure the
ground is level and firm. If necessary,
use a sturdy board under the jack.
- Always store the vehicle tool kit, the jack
and the replaced tire in the luggage com­
partment
¢ page 132.
{!) Tips
Before changing the wheel, you must acti­
vate the jacking mode, so that the auto­ matic controls for the Adaptive Air Sus­
pension* do not make it more difficult to
lift the vehicle with the jack¢
