cautions
¢ .&. .
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions. However, in winter we recommend using
winter or all season tires on
all four wheels, be­
cause this will improve the
broking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
c::> page 259, Snow chains.
Replacing tires
For vehicles with all wheel drive, only wheels with
the same rolling circumference should be used .
Avoid using tires with different tread depths
c::> page 251, New tires or wheels.
Offroad vehicle?
Your Aud i is not an offroad vehicle - there is not
enough ground clearance. For this reason, avoid
difficult terrain.
,& WARNING
- Also, in vehicles with all wheel drive, adapt
your driv ing style to the current road and
t ra ffic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the r isk of an acci­
dent.
- The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi­
cle. Do not be tempted to accelerate to a
high speed when the road is slippery, be­
cause this increases the risk of an accident.
- Note that on wet streets, the front wheels
can "hydroplane" if driving at speeds that
are too high. Unlike front whee l drive
vehicles, the engine does not rev higher sud­
denly when the vehicle begins hydroplaning.
For this reason, adapt your speed to the
road conditions to reduce the risk of an acci­
dent.

What impairs driving safety?
Safe driving is dire ctly related to the condition of
the vehicle, the driver as well as the driver's abili­
ty to concentrate on the road without being dis ­
tracted.
T he dr iver is responsib le for the sa fe ty of the ve ­
hicle and a ll of its occupants. If your ability to
drive is impai red, safety risks for everybody in the
vehicl e inc rease and you a lso become a hazard to
everyone else on the road
¢ A_ . Therefore:
.. Do not let yourse lf be distracted by passenge r
or by using a ce llular telephone .
.. NEVER drive when your driving ability is im ­
pa ired (by med ications, alcohol, drugs, etc.) .
.. Observe all traffic laws, rules of the road and
speed lim its and plain common sense .
.. ALWAYS adjust your speed to road, traffic and
weather conditions .

Airbag syste m
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
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, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic cont rol u nit. Some suspension c hanges
can, for example, increase the fo rce leve ls meas­
u red by the sensors and make t he a irbag system
deploy in crashes in which it wou ld not deploy if
the changes had not been made. Other kinds of
changes may reduce the force levels measured by
the sensors and prevent the a irbag from deploy­
ing when it should.
A WARNING
-
Changing the vehicle's suspension including use of unapproved tire-rim combinations can
change Advanced Airbag perfo rmance and in­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
ter istics as the components o riginally instal­
led on your vehicle .
-Never use tire-rim combin ations that have
not been approved by Audi .

Child sa fety
Advanced front airbag system and children
Your veh icle is equipped w ith a front "Advanced
A irbag System" in comp liance w it h United States
F edera l Motor Vehicle Safety Standard ( FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your vehicle was manufactured.
The Advanced Airbag system in your veh icle has
been certified to meet the " low-risk" require ­
ments for 3- and 6-year old children on the pas­
senger 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 a irbag inflates. In addit ion, the
system has been certified to comply w ith the
" su ppress io n" req uirements of the Safety S tand­
ard, to tu rn off the front airbag for infants up to
12 months who are restrained on the front pas­
senger seat in child restraints that are listed in
the Standard.
E ven tho ugh yo ur vehicle is equipped with an
Ad a
vanced Airbag system, a chi ld should a lways ride
in the seat proper ly restrained for its age and
size. The airbag on the passenger side makes the
front seat a potentially dangerous p lace for a
child to r ide . The front seat is not the safest place
for a child in a forward-facing child safety seat .
It
can be a very dange rous place for a n infant or a
larger child in a rearward-fac ing seat.
The vehicle's Advanced Airbag System has a ca­
pac itive passenger detect ion system in the front
passenger seat cush ion that ca n detect the pres­
ence of a baby or a child in a ch ild restraint sys­
tem on t his seat .
The capac it ive passenger detect ion system regis ­
ters the changes that result in an electr ical field
when a c hild, a child restra int, and a baby blanket
a re on the front passenge r seat. The change in
t he meas ured capacitance due to t he p resence o f
a child, a chi ld restraint, and a baby b lanket on
the front passenger seat is re lated to the chi ld
restraint system resting on the seat . The meas ­
ured capacitance of a ch ild restraint system var-
218
ies depending on the type of system and specific
make and mode l.
The elect rical capac ita nce of the va rious types,
makes, and models of child restra in ts speci fied
by the U.S . National Highway Tra ffic Safety Ad­
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys ­
tem control unit together with the capacitances
typ ica l of infants and a 1-year old child. When a
c hi ld restraint is used on the front passenger
seat w it h a typical 1 year-old infant, t he Ad­
vanced Airbag System compares the capacitance measured by the capacitive passenge r detect ion
system wi th the data stored in the e lec tronic co n­
tro l unit .
Child restraints and Advanced front airbag
system
Regardless of the ch ild restraint that you use,
make sure that it has been certified to meet Safe­
ty Standards and has been cert ified by its manu ­
factu rer for use w ith an airbag . If in exceptional
c ir cumstances you m ust use it on the front pas­
senger seat, ca refully read all of the information
o n chi ld safety and Advanced Airbags and heed
a ll of th e app licab le WARNINGS . Make certain
that the chi ld and chi ld restraint are correctly
recognized by the capacitive passenger detection
system in the front passenger seat, that the front passenger a irbag is turned off, and that the air­
bag status is always correct ly signa led by the
PASSENGER AIR BAG OFF ~; light.
Many types and models of child restra ints have
been available over the years, new models are in­
troduced regularly incorporating new and im­
proved designs and older models are taken out of
production . Ch ild rest rai nts are not standa rdized .
Child res tra ints of the same type typically have
d iffe rent weights and sizes and diffe re nt "foot ­
pr ints", the size and shape o f th e bo ttom of the
ch ild restraint that sits on the seat, w hen they
are installed on a vehicle seat . These differences
make it virtua lly impossib le to certify comp liance
with the requirements for advanced a irbags w ith
each and every child restra int that has ever been
sold in the past or will be sold over the course of
the useful life of your veh icle .

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout
