Booster seats and safety belts
Properly used booster seats can help protect
children weighing be tween 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. 14 2 Re ar seat: child pro perl y restrain ed in a booster
seat
T he vehicle's safety belts alone will not fit most
children unti l they are at least 4
ft . 9 in . (57 in­
ches/1.45 meters) tall and we igh about 80 lbs .
(36 kg) . Booster seats raise these children up so
that the safety bel t will pass properly over the
stronger parts of their bodies and the safety belt
can help protect them in a c rash.
.,. Do not use the co nvertib le locking retractor
when using the vehicle's safety bel t to restra in
a ch ild on a boos ter sea t.
.. The shoulder be lt must lie as close to the cen­
te r of the child's co llar bone as possible and
must lie flat 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
ac ross the stomach or abdomen . Make sure the
belt lies flat and snug . Pull on the belt to tight­
en if necessary .
.,. If you must transpo rt an older chi ld in a boos­
ter seat on the front passenger sea t, you can
use the safety belt height adj ustmen t to help
adjust the shoulder port ion properly .
Child sa fe ty
.. Secure unused sa fety belts on the rear seat
i=> page 177.
Childre n up to at least 8 yea rs old (over 40 lbs or
18 kg) are best protected in child safety seats de ­
s igned for their age and weight . Experts say that
the skeleta l structure, particularly the pelvis, of
these chi ldren is not f ully deve loped, and they
must not use the vehicle safety belts without a
su itable child restraint .
It is usually best to put these child ren in appro­
priate booster seats . Be sure the booster seat
meets all applicab le safety standards.
Booster seats ra ise the seating position of the
child and reposit ion both the lap and shoulder
parts of the safety belt so that they pass across
the chi ld's body in the right places. The routing of
the be lt over the chi ld 's body is very important
for the ch ild's protection, whether or not a boos ­
te r seat is used . Children age 12 and under must
always ride in the rear seat.
Children who are at least 4
ft. 9 in . (57 inches/
1.45 meters) tall can generally use the vehicle's
th ree po int lap and shoulder be lts . N ever use the
lap belt portion of the veh icle's safety belt a lone
to re strain any child , regardles s of how b ig the
c hi ld i s. A lways remember that c hildren do no t
have the pronounced pe lv ic struct ure required for
the p roper function of lap belt port ion of the ve­
hicle 's t hree point lap and shoulder be lts . The
c h ild 's safety abso lutely requires that a lap belt
portion of the safety belt be fastened snug ly and
as low as possible around the pelvis . Never let
the lap belt portion of the safety belt pass over
the ch ild's stomach or abdomen .
In a crash, a irbags must inflate within a blink of
an eye and with considerable force . In order to do
its job, the airbag needs room to inflate so that it
will be the re to p rotect the occ upant as th e occu­
pant moves fo rward into the airbag .
A vehicle occupant who is out of posit ion and too
close to the a irbag gets in the way of an inflating
airbag . When an occupan t is too close, he o r she
will be struck violent ly and w ill receive ser ious or
poss ibly eve n fa ta l injury. .,,.

means the combined we ight (in
excess of those standard items
which may be replaced) of auto­
matic transmission, power stee r­
ing, power brakes , power win­
dows, power seats, radio, and heater, to the extent that these
items are available as fac to ry-in­
stalled equipment (w hether in ­
stalled or not).
Aspect ratio
means the ratio of the height to
the width of the tire in percent .
Numbers of 55 or lower ind icate a
low si dewall for imp roved steer­
ing response and better overa ll
handling on dry pavement . .,.

Tires and wheel s
-Always adapt your driving to the road and
traff ic conditions. Dr ive carefully and red uce
yo ur speed on icy or slippery roads. Even
winter tires can lose tract io n on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow a nd ice. Summer
tires cause less road noise, tire wear and fuel
consumptio n.
(D Tips
You can also use all season tires instead of
w inte r tires. Please note that in some coun­
t ries w here winter tires are requ ired, on ly win­
t er tire s wi th the .& symbol may be pe rm it­
t ed.
Snow chains
Snow chains improve traction in the snow .
.,. Only install snow chains on the front wheels.
Th is applies also to veh icles with all wheel
drive* .
.,. Ch eck and correct the seating of th e snow
c h ains if necessa ry afte r dri ving a few feet. Fo l­
l ow the ins tructions from the manuf acturer.
.,. Note t he max imum permit ted speed w hen driv ­
ing with snow chains . Do not exceed 30 mph
(SO km/h).
Snow chains not only improve the
driving in win ­
ter road conditions, but a lso t he
braking .
Use of s now chai ns is o nly pe rm itted with certa in
r im/t ire comb ina tion s due to techn ica l reason s.
Chec k w ith an au thori zed A udi d ealer or au tho r­
ized A udi Service Facility to see if yo u may use
snow cha ins.
Use
fine -mesh snow chain s. They mus t not add
mo re th an 0 .5 3 inch ( 13.S mm) in height, in clu d­
ing the chain lock.
You must remove the chai ns when dr iv ing on
roads tha t are
free of snow. W hen r oads are free
of snow, snow chains can imp air handling an d

'
damage the tires, and the chains wi ll quick ly be
dest royed.
A WARNING
Using incorrect snow chains o r insta lling snow
cha ins incor rectly can res ult in loss of veh icle
c o ntrol, which increases the risk of an acc i­
dent.
(D Note
- Snow chains can damage the rims/wheel
cove rs* if the c hains come into direct c on­
tact with them. Remove the wheel covers*
first . Use coa ted snow cha ins.
Low aspect ratio tires
Your A udi is fac to ry-eq uipped w ith low aspect ra­
t io t ires. These t ires have been thoroug hly tes ted
a nd been sele cted specifi ca lly f or your mode l for
the ir su perb pe rformance, r oad fee l and h andlin g
u nder a var iety of dr iv ing con ditions. As k your au ­
t h orized Aud i dea le r fo r more details .
The low aspe ct ratio of these tires is ind icated by
a n umer al of
55 or less in the t ire's s ize design a­
tion . The nume ral represents the ratio of the
ti re's si dewall height in relatio n to its tread width
expressed i n pe rcentage. Conventional tires have
a height/width rat io o f 60 o r more .
The performance of low-aspect-ratio tire s is par­
ticularly sensitive to imprope r inflation pres­
sure. It is therefore important that low aspect ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained. Tire pressures should be checked at least once a month and always
b efor e a long trip

What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged mo re eas i­
l y by impact w ith potho les, c urbs , g ull ies o r
