The following examples are unusual situations
where it may make sense to switch offroad mode
on to allow the wheels to spin:
- Rocking the vehicle to free it when it is stuck
- Dr iving in deep snow or on loose ground
- Driving on rough terrain when much of the car's
weight is lifted off the wheels (axle articula­

function is limited or switched off. The amount of
stabilization control will differ depending on the
level. For your safety, switch the offroad mode off in
advance.

Airbag syste m
-Fo r th eir own safety, all children, especially
12 years and younger, shou ld always ride in
the back properly restra ined for their age
and size .
Advanced front airbag system
Your veh icle is equipped with a front Advanced
Airbag System in compliance with Un ited States
F edera l Moto r Vehicle Safety Standard
208, as
well as Canada Motor Vehicle Safety Standard (C MVSS)
208 as app lica ble at the time your ve hi­
cle was manufactured.
The front Advanced Airbag System supp lements
the safety belts to prov ide addi tional pro te ct ion
for the dr iver's and front passenger's he ads and
upper bodies in frontal crashes. The airbags in ­
flate only in frontal impacts w hen the veh icle de ­
celeration is high enough .
The front Advanced Airbag System for the front
seat occupants is not a substitute fo r your safety
be lts. Rather, it is part of the overa ll occupant re­
straint system in your vehicle . Always remember
that the airbag system can on ly help to protect
you, if you are sitting upr ight, wearing your safe­
ty belt and wearing it properly . This is why you
and your passengers must always be properly re­
stra ined, not just because the law requ ires you to
be.
The Advanced Airbag System in your veh icle has
been cert ified to meet the "low risk" require­
men ts for 3 and 6 yea r-o ld children on the pas­
senge r side and very sma ll adults on the d river
side. The low r is k dep loymen t cr ite ria are intend­
ed to he lp reduce t he r is k of injury through inter ­
action with t he front ai rbag that can o ccu r, fo r
examp le, by being too close to the steering wheel
and instr ument pane l when the airbag inflates.
I n addi tion, the sys tem has been certified to
comp ly w ith the "suppression" requirements of
the Safety Standa rd, to tu rn
off the front ai rbag
for infants 12 months old and yo unger who a re
restrained on the front passenger seat in c hild re­
stra ints that are listed in the Standard
¢ page 139, Child restraints and Advanced Air ­
bags.
122
"Suppression" requires the front airbag on the
passenger side to be turned
off if:
- a child up to abo ut one year of age is restraine d
on the fron t passenger seat in one of the rear­
facing or forward -facing infant restraints listed
in Federal Motor Vehicle Safety Standard
208
w ith which the Advanced A irbag System in yo ur
veh icle was certified. For a list ing of the child
restraints that were used to cert ify your vehi­
cle's compliance with the US Safety Standard
¢ page 139,
-weight less than a threshold leve l stored in t he
control u nit is detected on the front passenger
seat .
When a person is detected on the front passen­ ger seat, weig hing more than the total weight of
a ch ild that is about 1 year old restrained in one
of the rea r-facing or forward-fac ing infant re­
straints (listed in Federal Motor Vehicle Safety
Stan dard
208 w ith w hich t he Adv anced Airbag
System i n your veh icle w as certified), the fro nt
airbag on the passenger side may or may not de­
ploy .
The
PASSENGER AIR BAG OFF lig ht comes o n
whe n the ele ct ronic con trol uni t detects a tot al
weight on t he fron t passenger sea t that req uires
the front airbag to be turned
off . If the PASSEN·
GER AIR BAG OFF
light does not come on, the
front airbag on the passenger side has not been
turned
off by the control unit and can dep loy if
the control unit senses an impact t hat meets the
cond it ions stored in its memory .
If the total weight on the front passenger seat is
more than that of a typ ica l 1 yea r-old, but less
than the weight of a small adult, the front airbag o n the passenge r side may deploy (the
PASSEN­
GER AIR BAG OFF
light does not come on) .
For example , the airb ag may deploy if:
- a small ch ild that is heav ier than a typica l 1
year-o ld child is on the front passenger seat
(regard less of whether the child is in one o f the
child safety seats listed¢
page 139),
-a child who has outgrown ch ild restraints is on
the front passenger seat.

Child safety
A WARNING
Children on the front seat of any car even with
Advanced Airbags can be seriously injured or even killed when an airbag inflates. A child in
a rearward-facing child safety seat installed
on the front passenger seat will be seriously
injured and can be killed if the front airbag in ­
flates .
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child
against the backrest, center armrest, or
door .
- Always install rear-facing child safety seats
on the rear seat.
-If you must install a rearward facing child
safety seat on the front passenger seat in
exceptional circumstances and the
PASSEN­
GER AIR BAG OFF
light does not come on
and stay on, immediately install the rear­
facing child safety seat in a rear seating po­
sition and have the airbag system inspected
immediately by your Audi dealer.
A WARNING
If, in exceptional circumstances, you must in­
stall a forward-facing child restraint on the
front passenger's seat:
- Always make sure the forward-facing seat
has been designed and certified by its man­
ufacturer for use on a front seat with a pas­
senger front and side airbag.
- Always follow the manufacturer's instruc­
tions provided with the child safety seat or
carrier .
- Always move the front passenger seat to
the highest position in the up and down ad­
justment range and move it back to the
rearmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possible, before installing the for­
ward-facing child restraint.
- Always make sure that the safety belt upper
anchorage is behind the child restraint and
not next to or in front of the child restraint
so that the safety belt will be properly posi­
tioned.
138
- Always make sure that the PASSENGER AIR
BAG OFF
light comes on and stays on all the
time whenever the ignition is switched on.
(D Tips
Always replace child restraints that were in­
stalled in a vehicle during a crash. Damage 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 "Advanced
Airbag System" in compliance with United States
Federal 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 vehicle 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 airbag inflates. In addition, the
system has been certified to comply with the
"suppression" requirements of the Safety Stand­
ard, to turn 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.
Even though your vehicle is equipped with an Ad­
vanced Airbag system, all children, especially
those 12 years and younger, should always ride
in the back seat properly restrained for their age
and size. The airbag on the passenger side makes
the front seat a potentially dangerous place for a child to ride. The front seat is not the safest place
for a child in a forward-facing child safety seat. It
can be a very dangerous place for an infant or a
larger child in a rearward-facing seat.

New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility .
These facilities have the proper knowledge and are equipped with
the required tools and replace­
ment parts.
.,. New tires do not yet have the
optimum gripping properties. Drive carefully and at moderate
speeds for the first 350 miles (500 km) with new tires .
.,. Only use tires with the same de­
sign, size (rolling circumference)
and as close to the same tread pattern as poss ible on all four
wheels .
178
.,.Do not replace tires individually .
At least replace both tires on the
same axle at the same time.
.,. Audi recommends that you use
Audi Original Tires. If you would
like to use different tires, please
note that the tires may perform
differently even if they are the
same size ¢
,&..
.,. If you would like to equip your
vehicle with a tire/rim combina ­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi
dealer or authorized Audi Service Facility before making a pur­
chase ¢&, .
If the spare t ire is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
then only use the spare tire tem­
porarily in case of emergency and
drive carefully while it is in use. It
should be replaced with a regular
tire as soon as possible.
Applies to: vehicles with all wheel
drive: all four wheels must be
equipped with tires that are the
same brand and have the same
construction and tread pattern so
that the drive system is not dam­ aged by different wheel speeds . .,.

has the same circumference as
the regular tires.
& WARNING -
-Only use tire/rim combina­
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
-For technical reasons, it is not possible to use tires from oth­
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you select have enough clearance
to the vehicle . Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more
than six years old when abso-

lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on
your vehicle . Using them when
not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
