— the capacitive passenger detection system,
which switches the front seat passenger's fron-
tal Advanced Airbag on and off, detects a
change in the status of the front passenger
seat.
As soon as the PASSENGER AIR BAG OFF 7¥; ON
® light stops blinking, always make sure that the
airbag status (on or off) as shown by the light is
proper for the age, size and electrical capacitance
of the person occupying the front passenger seat.
Always make sure that the safety belt for the
front passenger seat is properly fastened.

occupied;
— will come on if the electrical capacitance meas-
ured by the capacitive passenger detection sys-
tem for the front passenger seat equals the
combined capacitance of an infant up to about
one year of age and one of the rearward-facing
or forward-facing child restraints listed in Fed-
eral Motor Vehicle Safety Standard 208 with
which the Advanced Airbag System in your vehi-
cle was certified; For a listing of the child re-
straints that were used to certify your vehicle's

Child safety

Child safety
Important information
Introduction
The physical principles of what happens when
your vehicle is in a crash apply also to children
=> page 183, What happens to occupants not
wearing safety belts?. But unlike adults and
teenagers, their muscles and bones are not fully
developed. In many respects children are at
greater risk of serious injury in crashes than
adults.
Because children's bodies are not fully developed,
they require restraint systems especially de-
signed for their size, weight, and body structure.
Many countries and all states of the United
States and provinces of Canada have laws requir-
ing the use of approved child restraint systems
for infants and small children.
Ina frontal crash at a speed of 20-35 mph
(30-56 km/h) the forces acting on a 13 lbs (6 kg)
infant will be more than 20 times the weight of
the child. This means the weight of the child
would suddenly be more than 260 lbs (120 kg).
Under these conditions, only an appropriate child
restraint properly used can reduce the risk of seri-
ous injury. Child restraints, like adult safety belts,
must be used properly to be effective. Used im-
properly, they can increase the risk of serious in-
jury in an accident.
If you must install a child restraint on the front
passenger seat in exceptional circumstances, be
sure to read and heed the important information
and warnings > page 190. Infants and other chil-
dren who are properly restrained in an appropri-
ate child restraint that is for their size and age
can benefit from the protection that supplemen-
tal side airbags provide in some kinds of crashes.
For more information please see information pro-
vided by the:

(NHTSA), currently at : http://www.safercar.gov
(for the USA)

Consult the child safety seat manufacturer's in-
structions in order to be sure the seat is right for
your child's size > page 213, Important safety
instructions
for using child safety seats. Please
be sure to read and heed all of the important in-
formation and WARNINGS about child safety, Ad-
vanced Airbags, and the installation of child re-
straints in this chapter.
There is a lot you need to know about the Ad-
vanced Airbags in your vehicle and how they work
when infants and children in child restraints are
on the front passenger seat. Because of the large
amount of important information, we cannot re-
peat it all here. We urge you to read the detailed
information in this owner's manual about airbags
and the Advanced Airbag System in your vehicle
and the very important information about trans-
porting children on the front passenger seat.
Please be sure to heed the WARNINGS - they are
extremely important for your safety and the safe-
ty of your passengers, especially infants and
small children.

ZA WARNING
All vehicle occupants and especially children
must be restrained properly whenever riding
in a vehicle. An unrestrained or improperly re-
strained child could be injured by striking the
interior or by being ejected from the vehicle
during a sudden maneuver or impact. An un-
restrained or improperly restrained child is al-
so at greater risk of injury or death through
contact with an inflating airbag.

ZA 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.

The effectiveness of winter tires is reduced great-
ly when the tread is worn down to a depth of
0.157 in (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re-
gardless of the remaining tread.
@) For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear, and fuel
consumption.
G) Tips
You can also use all season tires instead of
winter tires. Please note that in some coun-
tries where winter tires are required, only win-
ter tires with the “ symbol may be permit-
ted.
Snow chains improve both driving and braking in
winter road conditions.
> Only install snow chains on the front wheels.
> Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol-
low the instructions from the manufacturer.
> Note the maximum speed of 30 mph
(50 km/h). Observe the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author-
ized Audi Service Facility to see if you may use
snow chains.
You must remove the snow chains on roads with-
out snow. Otherwise, you could impair driving
ability and damage the tires.

ZA\ WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci-
dent.

CG) Note
— Snow chains can damage the rims and
wheel covers* if the chains come into direct
contact with them. Remove the wheel cov-
ers* first. Use coated snow chains.
— Using snow chains that add more than 0.53
in (13,5 mm) of height can severely damage
the wheel housings and other vehicle com-
ponents.
@) Tips
When using snow chains, it may be advisable
to limit the ESC > page 87.
ee cil med
Applies to: vehicles with low-profile tires
Compared to other tire/rim combinations, low-
profile tires offer a wider tread surface and a
larger rim diameter with shorter tire sidewalls.
This results in an agile driving style. However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi-
tion.
Low-profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers, and
curbs. Therefore, it is particularly important to
maintain the correct tire pressure > page 250.
To reduce the risk of damage to the tires and
rims, drive very carefully on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/cracks
on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an
authorized Audi dealer or authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand-
ard tires.

Driving in other
countries
Government regulations in the United States and
Canada require motor vehicles to comply with
emissions regulations and safety standards.
Therefore, vehicles that were produced for the
U.S. and Canadian markets are different from ve-
hicles produced for other countries.
If you plan to use your vehicle outside of the
United States or Canada, it is possible that:
— Fuel may have a significantly lower octane rat-
ing. Unsuitable fuels can cause engine damage.
— Proper maintenance and repair work may not
be possible because special service equipment,
tools, or measuring devices needed for your ve-
hicle may not be available.

— Replacement parts may not always be availa-
ble.
— Navigation systems for vehicles built for the
U.S.A. and Canada will not necessarily work in
Europe, and may not work in other countries.

General information
Due to the increasing complexity of technology in
these vehicles, as well as the safety and environ-
mental standards that apply, you can only per-
form a very limited amount of repairs and modifi-
cations to the vehicle yourself.
Proof of maintenance work may be required to
submit a claim within the warranty period.
We recommend that you have your vehicle serv-
iced by an authorized Audi dealer or authorized
Audi Service Facility and that Audi Genuine Parts
and Audi Genuine Accessories are used. This
helps to ensure that your vehicle's functionality,
performance, and safety are not impaired.
Maintenance and repairs
Your vehicle was designed to help keep mainte-
nance requirements to a minimum. Some regular
maintenance is required to help ensure that your
vehicle runs in a safe, economical, and reliable
manner. Please refer to your Warranty & Mainte-
nance Booklet for more detailed information
about vehicle maintenance.
When operating the vehicle under more extreme
operating conditions, for example when outside
temperatures are very low or in very dusty envi-
ronments, certain maintenance should be per-
formed between the specified intervals.
