Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs. and
80 lbs . (18 kg and 36 kg) who are less than 4
ft.
9 in. (57 inches/1.45 meters) tall.
Fig. 252 Rear seat; chi ld proper ly restrained in a booster
sea t
The vehicle's safety belts alone will not fit most
children until they are at least 4
ft. 9 in. (57 in­
ches/1.45 meters) tall and weigh about 80 lbs.
(36 kg). Booster seats raise these children up so
that the safety belt will pass properly over the
stronger parts of their bodies and the safety belt
can help protect them in a crash.
.,. Do not use the convertible locking retractor
when using the vehicle's safety belt to restrain
a chi ld on a booster seat .
.. The shoulder belt must lie as close to the cen­
ter of the child's collar bone as possible and
must lie fla t and snug on the upper body.
It
must never lie across the throat or neck. The
lap belt must lie across the pelvis and never
across the stomach or abdomen. Make sure the
belt lies flat and snug. Pull on the belt to tight­
en if necessary .
.,. If you must transport an older child in a boos­
ter seat on the front passenger seat , you can
use the safety belt height adjustment to help
adjust the shoulder portion properly .
.. Secure unused safety belts on the rear seat
r:=>page 301.
Children up to at least 8 years old (over 40 lbs. or
18 kg) are best protected in child safety seats
de­
signed for their age and we ight. Experts say that
the skeletal structure , part icularly the pelvis , of
these children is not fully developed, and they
Child safety
must not use the vehicle safety belts without a
suitable child restraint .
It is usually best to put these children in appro­
priate booster seats. Be su re the booster seat
meets all applicab le safety standards .
Booster seats raise the seating position of the
child and reposition both the lap and shoulder
parts of the safety belt so that they pass across
the child's body in the right places. The routing of
the belt over the chi ld's body is very important
for the ch ild's protection, whether or not a
boos­
ter seat is used. Children age 12 and under must
always ride in the rear seat.
Ch ildr en who are at least 4
ft. 9 in. (57 inches/
1.45 meters) tall can generally use the vehicle 's
three point lap and shoulder belts . Never use the
lap belt portion of the vehicle 's safety belt alone
to restrain any ch ild, regard less of how big the
ch ild is. Always remember that childr en do not
have the pronounced pelvic structure required for
the proper function of lap belt portion of the
ve­
hicle's three point lap and shoulder belts . T he
child's safety absolutely requires that a lap belt
portion of the safety belt be fastened snugly and
as low as possible around the pe lvis. Never let
the lap belt portion of the safety belt pass over
the child 's stomach or abdomen .
In a crash, airbags must inflate within a blink of
an eye and with considerab le force. In order to do
its job, the airbag needs room to inflate so that it
will be there to protect the occupant as the
occu­
pan t moves forward into the airbag .
A vehicle occ upant who is out of position and too
close to the a irbag gets in the way of an inflating
airbag. When an occupant is too close , he or she
will be struck violently and will receive serious or possibly even fata l injury .
In order for the airbag to offer protection, it is
important that all vehicle occupants, especially
any children, who must be in the front seat
be­
cause of exceptiona l circumstances, be properly
restrained and as far away from the airbag as
poss ible. By keeping room between the child 's

the risk of a n acc ident beca use it can cause
the tire to burst.
- Always adapt your driving to the road and
traff ic conditions. Drive carefully and red uce
yo ur speed on icy or slippery roads. Even
winter tires can lose traction on b lack ice.
@ For the sake of the environment
Reinstall summe r tires at the approp riate
time, because they provide better hand ling
when roads are free of snow and ice. S ummer
tires cause less road noise, tire wear and fuel
consumption.
(D Tips
You can also use all season tires instead of
w inter t ires. Please note that in some coun­
tries w here w inte r ti res are req uired, only
w inter t ires with the
& symbol may be per ­
m itted.
Snow chains
Snow ch ains not only i mprove the d riving in win ­
t er ro ad cond itions, b ut also the brak ing.
... Only insta ll snow chains o n the front wheels .
T h is applies also to ve hicles w ith all wheel
drive* .
... Check an d cor rect the sea ting of the snow
c h ains a fte r dr iv ing a few feet, i f necessary. Fo l­
l ow the instructions from the manufacturer .
... Note the maximum permitted speed when d riv ­
ing with snow chains . Do not exceed 30 mp h
(SO km/h).
Use of snow chains is on ly pe rmitted with certain
rim/t ire combinations due to technical reasons.
Check with an authorized Audi dealer o r autho r­
ized Aud i Service Fac ility to see if yo u may use
snow chains.
Use
fine -mesh snow chains . They must not add
more t han 0.53 in (13.5 mm) in height, includ ing
the chain lock .
You must remove the snow c hains on roads wit h­
out snow. Othe rw ise, you could impa ir dr iv ing
ab ility and damage the tires.

A WARNING ~
Using incorrect snow chains or installing snow
cha ins i ncor rectly can result in loss of veh icle
con trol, which increases the risk of a n acci­
d ent.

Low-profile tires
Applies to: vehicles with low-profile tires
Your vehicle is equip ped wi th low -profi le t ires* at
t h e factory. Compa re d t o o ther tire/r im com bina ­
tions, low -profi le tires offer a w ider tread surface
and a larger rim diameter with shorter tire side­
walls . This results in an agile dr iv ing style. How­
ever, it may reduce the leve l of com fort and in­
crease road noise whe n driving on roads in poor
cond it ion.
Low-p rofile ti res can become damaged mo re
q uick ly than standard tires when dr iv ing ove r
l a rge bumps, potholes, manhole covers, speed
bumps and curbs . Therefore, it is particularly im­
po rtan t to maintain the correct tire pressure
<:;> page 344.
To reduce the risk of damage to the tires and
rims, drive very caref ully on poor roads.
Check your wheels regu larly eve ry 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 o r damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dea ler or authorized Audi

wash operator to reduce the risk of acci­dents.
- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings .
- After washing the vehicle, the brak ing effect
may be delayed due to mo isture on the
brake rotors or ice in the w inter . This in­
creases the risk of an acc ident. The brakes
must be d ried fi rst w ith a few careful b rake
applications.
(D Note
- If you wash t he vehicle in an automatic car
wash, yo u m ust fold the exte rior m irrors in
to reduce the risk of damage to the mirrors.
Power folding exte rior m irrors* must on ly
be fo lded in a nd out using the power folding
fu nct ion.
- To reduce the risk of damage to the rims
and tires, compare the width between the
whee ls on your vehi cle w it h t he dis tan ce be­
tween the g uide rai ls in the
car wash.
- To reduce t he risk of damage, compare the
height and width o f you r vehicle wi th the

- T o red uce the risk of pa int damage, do not
was h the vehicle in d irect sun light .
- T o red uce the risk of d am age to the s urf ace,
do not use insect removing sponges, k itche n
sponges or similar items .
- Mat te finish painted veh icle components:
- To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax .
- Never use protective wax. It can destroy
the matte finish effect .
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint . The paint cou ld be damaged
when the stickers or magne ts are re­
moved .
@ For the sake of the environment
Only wash t he vehicle in facilities s pec ially de­
s ign ed for that pu rpose . This will reduce the
