chlorate. When the vehicle or parts of the
restraint system including airbag modules
and safety belts wit h pretens ioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authorized
Aud i dea ler is familiar wit h these requ ire­
ments and we recommend that you have
your dea le r perfo rm this se rv ice for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-r im combinations not approved by Aud i,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion st ruts, shock absorbers etc. can change
the forces that are measured by the a irbag
sensors and se nt to the electron ic control
un it. Some suspension changes can, for exam­
p le, increase the force levels meas ured by the
sensors and make the airbag system deploy in
crashes in which it would not deploy if the
changes had not been made. Other kinds of
changes may reduce the force levels meas­ ured by the sensors and prevent the a irbag
from deploying when it should.
A WARNING
Changing the vehicle's suspension includ­
ing use of unapproved tire -rim combina­
tions can change Advan ced A irbag per­
formance and increase the risk of serio us
personal in jury in a crash.
- Never install suspension components
that do not have the same performance character istics as the components origi­
nally installed on your vehicle.
- Never use tire-rim combinatio ns that
have not been approved by A udi.
Knee airbags
Description of knee airbags
Applies to vehicles: with knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants.
F ig . 1 65 Driver's knee airbag
The driver knee airbag is in the ins trumen t
pane l underneath t he steering wheel
¢ fig. 165, the airbag for the passenger is at
about the same height in the instrument pan­
el underneat h the glove compartment.
T he knee airbag offe rs additional p rotection
to the driver 's and passenger's knees and up­
per and lower th igh areas and supplements
the protection provided by the safety belts.
If t he front airbags dep loy , the knee ai rbags
also dep loy in frontal coll isions when the de­
ployment threshold stored in the contro l unit
is met
¢ page 15 7, More important things to
know about front airbags.
In addition to their norma l safety function,
safety belts help keep the dr iver or front pas­
senger in position in a fronta l collision so that
the a irbags can provide supplemental protec­
t ion .
The airbag system is not a substit ute for your
safety belt. Rather, it is part of the overa ll oc­
cupant restra int system in your vehicle. Al­
ways remember that the a irbag system can
o nly help to protect you if you are weari ng
your safety belt and wea ring i t properly. This
is why you should always wear your safety
belt, not just beca use the law requi res you to
do so

182 Child Safety -Always follow the manufacturer's in­
structions provided with the child safety
seat or infant carrier.
- Always move the front passenger seat in­
to the rearmost position of the passen­
ger seat's fore and aft adjustment range,
and as far away from the airbag as possi­ ble before installing the child restraint .
- Always make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its
fore and aft adjustment range.
-Always make sure the backrest is in an
upright position.
- Never place or use any electrical device (such as a laptop, CD player, electronic
games device, power inverter or seat
heater for child seats) on the front pas­
senger seat if the device is connected to
the 12-volt socket or the cigarette light­
er socket.
- If a seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys­
tem on this seat.
- Make sure that there are no wet objects
(such as a wet towel) and no water or
other liquids on the front passenger seat
cushion.
- Never place objects on the seat (such as
a laptop, CD player, electronic games de­
vice, power inverter or seat heater for child seats). These may influence the
electrical capacitance measured by the
capacitive passenger detection system
and can also fly around in an accident
and cause serious personal injury.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched
on.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install the forward-facing child seat
at a seating position on the rear seat and have the airbag system inspected by your
authorized Audi dealer. -
Take the child restraint off the front pas­
senger seat and install it properly at one
of the rear seat positions if the
PASSEN­
GER AIR BAG OFF
light does not stay on
whenever the ignition is switched on.
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. 175 Rear seat: child properly restrained in a boos­
te r seat
The vehicle 's safety belts alone will not fit
most children until they are at least 4 ft . 9 in.
(57 inches/1.45 meters) tall and weigh about
80 lbs. (36 kg). Booster seats raise these chil­
dren up so that the safety belt will pass prop­
erly 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 re­
strain a child on a booster seat.
.. The shoulder belt must lie as close to the
center of the child's collar 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 across the stomach or abdomen .
Make sure the belt lies flat and snug. Pull on
the belt to tighten if necessary .
.,. If you must transport an older child in a
booster seat on the front passenger seat,
you can use the safety belt height adjust­
ment to help adjust the shoulder portion
properly. ..,.

Make sure that the cooling system has enough
fluid.
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the cold tire pressure listed under
"Full load" on the label located on the driver's
side B-pillar (visible when the door is open).
Inflate trailer tires to trailer and tire manufac­
turers' specifications.
Lights
Check to make sure both vehicle and trailer
lights are working properly.
Safety chains
Be sure trailer safety chains are properly con­
nected from the trailer to the hitch on the ve­
hicle. Leave enough slack in the chains to per­
mit turning corners . When you install safety
chains, make sure they will not drag on the
road when you are driving.
The chains should cross under the trailer
tongue to prevent it from dropping in case of
separation from the hitch.
Adjusting the Audi drive select
Make sure the vehicle is on a level surface be­
fore hitching up the trailer and before adjust­
ing the tongue weight. The vehicle must be in
auto or comfort driving mode and not raised
qpage 102, ~CD .
Make sure that the vehicle is lowered. In Info­
tainment, select:
ICARI function button> Low­
er
control button.
If you must drive under poor road conditions,
you can raise the vehicle
after coupling the
trailer or
after adjusting the tongue weight
qpage 104.
- Changes in temperature or load can af­
fect the height of the vehicle .
- Always select
auto or comfort mode.
Otherwise, the tongue load specified for
your vehicle will no longer be applicable.
Trailer towing
Driving instructions
Driving with a trailer always requires extra
care and consideration .
To obtain the best possible handling of vehicle
and trailer, please note the following:
... Do not tow a loaded trailer when your car it­
self is not loaded.
... Be especially careful when passing other
vehicles.
... Observe speed limits .
... Do not drive at the maximum permissible
speed.
... Always apply brakes early .
... Monitor the temperature gauge.
Weight distribution
Towing a loaded trailer with an empty car re­
sults in a highly unstable distribution of
weight. If this cannot be avoided, drive at very
low speeds only to avoid the risk of losing
steering control.
A "balanced" rig is easier to operate and con­
trol. This means that the tow vehicle should
be loaded to the extent possible and permissi­
ble, while keeping the trailer as light as possi­
ble under the circumstances. Whenever possi­
ble, transfer some cargo to the luggage com­
partment of the tow vehicle while observing
tongue load requirements and vehicle loading
considerations.
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed. Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -particularly
when going downhill .
Reduce vehicle speed
immediately if the trail­
er shows the slightest sign of swaying .
Do not
try to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds
for vehicles towing trailers are lower than for
regular vehicles . ..,..

242 Tires and wheels
-If you notice unusual vibra­
tion or if the vehicle pulls to
one side when driving, al­
ways stop as soon as it is
safe to do so and check the
wheels and tires for dam­
age.
0 Note
-Please note that summer and winter tires are de­
signed for the conditions
that are typical in those sea­
sons. Audi recommends us­
ing winter tires during the
winter months. Low tem­ peratures significantly de­
crease the elasticity of
summer tires, which affects
traction and braking ability. If summer tires are used
in
very cold temperatures, cracks can form on the tread
bars, resulting in perma­
nent tire damage that can
cause loud driving noise and
unbalanced tires. Audi is not
responsible for this type of
damage.
-Burnished, polished or chromed rims must not be used in winter road condi­
tions. The surface of the
rims does not have suffi­
cient corrosion protection
for this and could be perma­
nently damaged by road salt
or similar substances.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in
excess of those standard items
which may be replaced) of auto­ matic transmission, power
steering, power brakes, power
windows, power seats, radio, and heater, to the extent that
these items are available as fac­
tory-installed equipment (whether installed or not).
Aspect ratio
means the ratio of the height to
the width of the tire in percent.
Numbers of 55 or lower indi­
cate a low sidewall for im­
proved steering response and
better overall handling on dry
pavement.

260 Tires and wheels
A WARNING
Sudden tire failure can lead
to loss of control, a crash and serious personal injury!
-Never drive a vehicle when the tread on any tire is worn down to the wear indica­
tors.
-Worn tires are a safety haz­
ard, they do not grip well on
wet roads and increase your risk of "hydroplaning" and
loss of control.
-Always keep chemicals that
can cause tire damage, such
as grease, oil, gasoline and brake fluid away from tires.
-Tires age even if they are
not being used and can fail
suddenly, especially at high
speeds. Tires that are more
than 6 years old can only be used in an emergency and
then with special care and at lower speeds.
-Never mount used tires on your vehicle if you are not sure of their "previous histo­
ry." Old used tires may have
been damaged even though
the damage cannot be seen
that can lead to sudden tire
-failure and loss of vehicle control.
New tires and replacing
tires and wheels
New tires and wheels have to
be broken in.

Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed r ims. If differen t rims are fit­
ted, the correct wheel bolts with the right l ength and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -eve n if it
i s the same model
~ page 296.
_&. WARNING
Improperly tig htened or maintained whee l
bolts can become loose ca using loss of
contro l, a co llision and serious persona l in­
jury.
- Always keep the wheel bolts and the threads in the wheel hubs clean so the
whee l bolts can turn easily and be prop­
erly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose wh ile driving if greased or
o iled, even if tightened to the specif ied
torque .
- Only use wheel bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle .
-Always maintain the correct tighten ing
torque for the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor ­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cl e is moving.
If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be­
come loose.

Low aspect ratio tires
Your Audi is factory-equ ipped w ith low aspect
ratio tires . These tires have been thoroughly
tested and been selected specifically for your model for their superb perfo rmance, road fee l
and hand ling u nder a variety of driving condi­
tions . Ask your au thorized Aud i dealer for
more details .
T he low aspect ratio of these t ires is ind icated
by a numera l of
55 or l ess in the tire's si ze
designation. The n umera l represents the ra tio
of the ti re's sidewall height in relation to its
tread width expressed in percentage . Conven­
tiona l tires have a height/width ratio of 60 or
more.

What you c an do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact w it h potholes, curbs, gull ies

In order to minimize the occurrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the following p re ca u­
tions:
- Always ma inta in recommended inflation
p ressures . Check your tire pressu re eve ry
