Child safety
Important information
Introduction
The rear seat is generally the safest place in a
collision .
The physical principles of what happens when
your vehicle is in a crash apply also to children
c:> page 191, 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 r isk of serious injury in crashes than
adults .
Because children's bodies are not fu lly devel­
oped, they requ ire restraint systems especially
des igned for their size, we ight, and body struc­
ture. Many countr ies 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 .
I n a frontal crash at a speed of 20- 3 5 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 chi ld
would suddenly be more than 260 lbs (120 kg). Under these conditions, only an appropriate child
restraint properly used can reduce the risk of se ­
rious injury . Child restraints, l ike adult safety
belts, must be used properly to be effective .
Used imp roperly, they can increase the risk of se­
rious injury in an accident.
All ch ildren, especially those 12 years and young­
er must always ride in the back seat proper ly re­
stra ined for their age and size. If you must install
a child restra int on the front passenger seat in
exceptional circumstances, be sure to read and
heed the important information and warnings
c:> page 198. Infants and other children who are
properly restrained in an appropriate child re­
straint that is for their si ze and age can benefit
from the protection that supplemental side air­
bags provide in some kinds of crashes.

(NHTSA), currently at: http :/ /www.safe ­
rcar.gov (for the USA)
- Transport Canada Information Centre, current-

Consult the chi ld safety seat manufacturer's in­
structions in order to be sure the seat is right for
yo ur child's size
c:> page 225 , 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,
Advanced Airbags, and the installation of child restra ints 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 informat ion, we cannot re­
peat it all he re . We urge you to read the detailed
information in this owner 's ma nual about airbags
and the Advanced Airbag System in your vehicle and the very important information about trans ­
porting children on the front passenger seat.
P lease 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 .
A WARNING
-- Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seat ing pos ition. Always restrain
any child age 12 and under in the rear.
- All vehicle occupants and especially children must be restrained prope rly whenever r iding
in a vehicle. An unrestra ined or improperly
rest rained child cou ld be inju red by striking
the interior or by being ejected from the ve­ hicle during a sudden maneuver or impact.
An unrestrained or improperly restrained
child is also at greater risk of injury or death
through contact w ith an inflating a irbag.
-A suitable ch ild restraint properly installed
and used at one of the rear seating positions
provides the h ighest degree of protection
for infants and small children in most acci­
dent situat ions.

of an accident.
Winter tires
W inter tire s significan tly improve the vehicle 's
handling when driving in w inter condi tions. Be­
cause of the ir construction (width, compound,
tread pattern) , summe r tires p rovide less trac­
tion o n ice and snow.
.. Use w inter t ires o n all four wheels .
.. Only use w inter t ires that are approved for your
vehicle .
.. Please note that the maximum permitted
speed may be lower with winter tires
¢ & -An
a utho riz ed Aud i dea le r o r authorized Audi Serv­
ice Facility can inform you about the maximum
permitted speed fo r you r tires.
.. Check the tire pr essu re after installing whee ls
¢ page 265.
The effectiveness of winter tires is reduced great ­
ly whe n the tread is wor n down to a depth of
0 .157 in (4 mm). The character istics of winter
tires also decrease great ly as the tire ages, re­
gardless of the remaining tread.
A WARNING
- Never dr ive faste r than the maxim um per ­
mitted speed for your t ires . This cou ld cause
the tires to heat up too much. This increases
t h e risk of an a cciden t be ca use i t can c ause
t h e tire to burst.
- Always adapt yo ur driv ing to t he r oad and
t ra ffic conditions. Drive ca refully and red uce
yo ur sp eed on icy or slippery roads. Even
winte r tires can lose traction on black ice .
@ For the sake of the environment
Reinstall su mme r tir es at the approp ria te
t ime, because they provide bet ter ha ndling
when ro ads are free of snow a nd ice. S ummer
t ires cause less road noise, ti re wea r and fuel
consumption.

(D Tips
You can also use a ll season tires instea d of
winter tires . Please note that in some coun­
tries where winter tires are required, on ly
winter tires w it h the
& symbol may be per­
mitted.
' Snow chains
S now cha ins not on ly improve the driv ing in win­
te r road cond it io ns, but a lso the b raking .
.. On ly install snow chai ns on the front wheels .
T his applies also to vehicles with all wheel
dr ive*.
.. Check and co rrect t he seating of the snow
chains after driving a few feet, if nece ssary. Fol­
low t he inst ructions from the m anufac turer.
.. Note the max imum speed of 3 0 mph (50 km/
h). Note the local regulations.
U se of snow c hains is only permitte d wit h cert ain
rim/ tire comb inat ions due to technical reasons.
Check with a n authorized Audi dealer or author ­
i zed Audi Service Facility to see if you may use
snow chains.
You m ust remove the snow chains on roads wi th­
out snow . Otherwise, you co uld impair driving
ability and damage the t ires .
A WARNING
Using incor rect snow chains or installing snow
cha ins incor rectly can result in loss of vehicle
control, which increases the risk of an acci­
dent .
(D Note
-Snow chains can damage the rims/wheel
covers* if the c hains come into direct con­
tact with them. Remove the w heel covers *
first . Use coated snow cha ins .
- Us ing snow c hains that add more tha n 0.53
in (13,5 mm) of height can seve rely damage
the whee l housings and o ther vehicle com­
ponents .

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra­
tio tires. These t ires have been thoroughly tested
and been selected specifically for your model for
their supe rb performance, road feel and handling
u nder a va riety of d riving conditions. As k your au­
thor ized Audi dealer for mo re details.
The low aspect ratio of these t ires is indicated by
a numeral of
55 or l ess in the tire's size designa­
tion. The numera l rep resents the rat io of the
tire's sidewall he igh t in relat io n to its tread w idth
expressed in pe rcen tage. Conventional t ires have
a height/w idth rat io of 60 or more .
The performan ce of low -a spe ct-ratio tire s is par­
ticular ly sen sit iv e to improper inflation pre s­
s ur e. It i s therefore import ant that low a spect
ratio tire s are infl ate d to the specified pre ssure
and that the inflation pre ssure i s regularl y
c hecked and mai nta ined . Tir e pre ssure s should
b e che cked at least once a month and alw ay s
before a long tri p ¢
page 265.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more easi­
ly by impact with potholes, curbs, gullies or
ridges on the road, particularly if the t ire is un­
derinflated .
In order to minimize the occurrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the follow ing precau­
tions:
- Always maintain recommended inflation pres­
sures. Check your tire pressure every 2,000
miles (3,000 km) and add a ir if necessary .
- Drive carefully on roads with potho les, deep
gul lies or ridges. The impact from driving
t h rough or ove r such obstacles can damage
you r tires. Impact w ith a curb may also cause
damage to your tires.
Wh eel s
- After any impac t, immed iate ly inspect your
tires or have them inspected by the nearest au­ thorized A udi dealer. Replace a damaged tire as
soon as possible.
- Inspect your tires every 2,000 mi les (3,000 km)
for damage and wear. Damage is not a lways
easy to see. Damage can lead to loss of air and
underinflation, wh ic h could eventually cause
tire fa ilure . If you believe that a t ire may have
been damaged, replace the tire as soon as pos­
sible.
- These tires may wear more quickly than others.
- Please also remember that, while these tires
delive r responsive handling, they may ride less
comfortably and make mo re noise than other
choices.
Reduced pe rfo rmance in winter /cold season
conditions
All t ires are des igned for certai n purposes. The
low aspect ratio, ultra h igh performance tires
o rigi na lly installed o n your vehicle are intended
fo r m aximum d ry and wet road per formance and
handling . They are not sui table for co ld, snowy or
icy weather conditions . If you drive under those
circumstances, you should equip yo ur vehicle
with all-season or winter tires, which offer better
tract ion under those conditions. We suggest you
use the recommended snow or all-season tires
specified for your veh icle, or their equivalent.
Refer to¢
page 2 70 for more detailed informa­
t ion regarding winter tires.

Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi ­
mately one minute and then remain continuously
illuminated . This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists .
When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly . Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function properly.
If the Tire Pressure Monitoring System
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 .
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread circumfer­
ence and vibration characteristics of the individu­
al tires. If the pressure changes in one or more
tires, this is indicated in the Infotainment system
display w ith an indicator light
RE and a message.
If only one tire is affected, the location of that
tire will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle
c::;, page 274 . The tire pressure moni­
toring system only monitors the tire pressure you have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
¢ page 265, fig. 199.
Wheels
Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if :
- the tire pressure in one or more tires is too low.
- the tire has structural damage.
- the tire was replaced or the tire pressure was
changed and it was not stored
c::;, page 274.
- the spare tire* is installed .

RE-Loss of pressure in at least one tire c::;, &,.
Check the tires and replace or repair if necessary.
Check/correct the pressures of all four tires and
store the pressure again in the Infotainment sys­
tem

pressure: malfunction! See owner's manual -If
mm appears after switching on the ignition or
while driving and then the indicator light
RE in
the instrument cluster also starts to blink for
about one minute and then stays on permanent­
ly, there is a system malfunction. Try to store the
correct tire pressures
c::;, page 2 74 . If the indica­
tor light does turn off or turns on again after a short period of time, drive to an authorized Audi
dealer or authorized Audi Service Facility immedi­
ately to have the malfunction corrected.
A WARNING
..-
- If the tire pressure indicator appears in the
display, reduce your speed immediately and
avoid any hard steering or braking maneu­
vers. Stop as soon as possible and check the
tires and their pressure.
- The driver is responsible for maintaining the
correct tire pressures . You must check the
tire pressures regularly .
- Under certain conditions (such as a sporty
driving style, winter conditions or unpaved
roads), the pressure monitor indicator may
be delayed.
- Do not use run-flat tires on your vehicle . Us­
ing them when not permitted can lead to
vehicle damage or accidents.

scope of maintenance and repairs which can be
carried out by vehicle owners.
Also, safety and
environmental
concerns place very strict limits
on the nature of repairs and adjustments to en­
gine and transmission parts which an owner can
perform .
Maintenance, adjustments and repairs usually re­
quire special tools, testing devices and other
equipment available to specially trained work­
shop personnel in order to assure proper per­
formance, reliability and safety of the vehicle and
its many systems .
Improper maintenance, adjustments and repairs
can impair the operation and reliability of your
vehicle and even void your vehicle warranty.
Therefore, proof of servicing in accordance with
the maintenance schedule may be a condition for
upholding a possible warranty claim made within
the warranty period.
Above all, operational safety can be adversely af­
fected, creating unnecessary risks for you and
your passengers.
If in doubt about any servicing, have it done by
your authorized Audi dealer or any other properly
equ ipped and qualified workshop. We strongly
urge you to give your authorized Audi dealer the
opportunity to perform all scheduled mainte­
nance and necessary repairs. Your dealer has the
facilities, original parts and trained specialists to keep your vehicle running properly.
Performing limited maintenance yourself
The following pages describe a limited number of procedures which can be performed on your vehi­
cle with ordinary tools, should the need arise and
trained personnel be unavailable. Before per­
forming any of these procedures, always thor­
oughly read all of the applicable text and careful­
ly follow the instructions given. Always rigorously
observe the
WARNINGS provided.
Before you check anything in the engine com­
partment, always read and heed all WARNINGS
c> & and c> & in Working in the engine compart­
ment on page 244.

A WARNING
-
- Serious personal injury may occur as a result
of improperly performed maintenance, ad­
justments or repairs .
- Always be extremely careful when working
on the vehicle. Always follow commonly ac­
cepted safety practices and general com­
mon sense. Never risk personal injury.
- Do not attempt any of the maintenance,
checks or repairs described on the following pages if you are not fully familiar with these
or other procedures with respect to the ve­ hicle, or are uncertain how to proceed.
- Do not do any work without the proper tools
and equipment. Have the necessary work
done by your authorized Audi dealer or an­
other properly equipped and qualified work­
shop.
- The engine compartment of any motor vehi­
cle is a potentially hazardous area. Never
reach into the area around or touch the radi­
ator fan. It is temperature controlled and
can switch on suddenly - even when the en­
gine is off. The radiator fan switches on au­
tomatically when the coolant reaches a cer­
tain temperature and will continue to run
until the coolant temperature drops.
- Always switch off the ignition before anyone
gets under the vehicle.
- Always support your vehicle with safety
stands if it is necessary to work underneath
the vehicle. The jack supplied with the vehi­
cle is not adequate for this purpose and
could collapse causing serious personal in­
Jury.
- If you must work underneath the vehicle
with the wheels on the ground, always make
sure the vehicle is on level ground, that the
wheels are always securely blocked and that
the engine cannot be started.
- Always make sure the transmission selector
lever (automatic transmission) is in P (Park
position) and the park brake is applied. ..,
