Improperly worn safety belts
Incorrectly positioned safety belts can cause
severe injuries.
Wear ing safety be lts imprope rly can cause se ­
rio us inj ury or death. Safety be lts can on ly
wo rk when they are correct ly positioned on
the body. Improper seating positions reduce
the effect iveness of safety belts and will even
increase the r isk of injury and death by mov­
ing the safety belt to cr itical areas of the
body. Imprope r seat ing pos it ions also in­
crease the risk of serio us in jury and death
when an air bag deploys and str ikes a n occu­
pant who is not in the correct seating posi­
tion . A d river is responsib le for the sa fety of
all vehicle occupants and especially for chi l­
dren. Therefore:
~ Never permit anyone to ass ume an incorrect
sitting position in the veh icle w hile traveling
¢&_ .
A WARNING
Imprope rly worn safety belts increase the
r isk of serious personal injury and death
whenever a veh icle is being used. -
Always make sure that all vehicle occu­
pants are co rrectly restrained and stay in
a correct seating position whenever the
veh icle is being used .
- Always read and heed all WAR NINGS and
other important information

Safety belt preten­
sioners
How safety belt pretensioners work
In front, side and rear -end collisions above a
particular severity and in a rollover , safety
belts are tensioned automatically.
Reversible safety belt tensioners
T he safety belts on the fro nt sea ts ar e e qui p­
ped with powe r reversib le tensioners . The fo l­
lowing functions a re ava ila bl e when the driv­
er's/front passenger's safety belts are fas­
tened :
- Automatic tens ioners : at the star t of a drive,
the safety belts automat ica lly adjust to the
passe nger afte r a certain time period or ve ­
hicle speed. To switch the automatic ten­
sioners off, select the following in the MMI:
! CARI function button> Car systems > Vehi­
cle settings > Seats > Driver's seat or Pas­
s enger's seat
> Automatic belt t ensioner >

reve rsible tensioning function in minor co lli­
sion s.
Pyrotechnic safety belt pretensioners
The safety belts are equ ipped with safety belt
pre tensioners . The system is act ivated by se n­
sors i n front, s ide and rear-end co llisions of
great severity and in a rollover. This tig htens

regulations must be observed. Your au­
thorized Audi dealer is familiar with these requirements and we recommend that you
have your dealer perform this service 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-rim combinations not approved by Audi, lower ing the vehicle, changing the stiffness of
the suspension, including the springs, suspen­ sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control
un it . Some suspension changes can, for exam­
ple, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in which it would not dep loy if the
changes had not been made. Other kinds of
changes may reduce the force Levels meas­
ured by the sensors and prevent the airbag
from deploying when it should.
The sensors in the safety belt buckle for the
driver and front passenger seat tell the elec­
tronic control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high­
er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular collision, it is poss ible that an airbag
will not deploy at a seating position where the
safety belt is being used but will inflate at the
position where the safety belt is not being
used. It is important that nothing interfere
with the safety belt buckles so that the sen­
sors can send the correct information about
safety belt use to the electronic control unit.
A WARNING
Changing the vehicle's suspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
formance and increase the risk of serious personal injury in a crash.
Airbag system 157
-Never install suspension components
that do not have the same performance
characteristics as the components origi­
nally installed on your vehicle .
- Never use tire-rim combinations that
have not been approved by Audi.
A WARNING
-
Items stored between the safety belt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the electronic con­
trol module and prevent the Advanced Air­
bag System from working properly.
- Always make sure that nothing can inter­
fere with the safety belt buckles and that they are not obstructed.
Knee airbags
Description of knee airbags
The knee airbag system con provide supple­
mental protection to properly restrained
front seat occupants.
Fig. 149 Driver 's airbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
¢ fig . 149, the airbag for the passenger is at
about the same height in the instrument pan­
el underneath the glove compartment.
The knee airbag offers additional protection
to the driver's and passenger's knees and up ­
per and Lower thigh areas and supplements
the protection provided by the safety belts.
If the front airbags deploy, the knee airbags
also deploy in frontal col lisions when the de­
ployment threshold stored in the control unit .,,.

174 Child Safety
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. 158 Rear seat: child properly restrained in a boos­
ter 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.
Children up to at least 8 years old (over 40 lbs
or 18 kg) are best protected in child safety
seats designed for their age and weight. Ex­
perts say that the skeletal structure, particu­
larly the pelvis, of these children is not fully developed, and they must not
use the vehicle
safety belts without a suitable child restraint.
It is usually best to put these children in ap­
propriate booster seats. Be sure the booster
seat meets all applicable 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 child's body is very
important for the child's protection, whether
or not a booster 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 in­
ches/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 child, regard ­
less of how big the child is. Always remember
that children do not have the pronounced pel­
vic structure required for the proper function
of lap belt portion of the vehicle's three point
lap and shoulder belts. The child's safety ab­
solutely requires that a lap belt portion of the
safety belt be fastened snugly and as low as
possible around the pelvis. 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 considerable 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 occupant moves forward into the air­
bag.
A vehicle occupant who is out of position and
too close to the airbag 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 fatal in­
Jury.
In order for the airbag to offer protection, it is
important that all vehicle occupants, especial-
ly any children, who must be in the front seat
because of exceptional circumstances, be
properly restrained and as far away from the
airbag as possible. By keeping room between ..,_

200 Trailer towing
Trail er load dis tr ibut ion
Be sure the load in the trai ler is held securely
in place to prevent it from shifting forward,
backward or sideways.

~ .&. in Driving instructions on page 201.
Engine cooling sy stem
Towing a tra iler makes the eng ine work hard­
er . It is important that the cooling system's
performance is up to the addit ional load .
Make sure that the cooling system has eno ugh
flu id.
Tir e pressure
When tow ing a tra iler, inflate the t ires of your
vehicle to the co ld tire pressure listed under
" Full load" on the label loca ted o n the dr iver's
side B-pillar (v is ible when the door is open).
I nflate trailer tires to tra iler and tire manufac­
turers' specifications.
Lights
Check to make sure both veh icle and trailer
l ights are wor king p roperly.
Safe ty chain s
Be sure tra iler safety cha ins are properly con­
nected from the trailer to the hitch on the ve ­
h icle . Leave enough slack in the chains to per­
mit turning corners. When you install safety
cha ins, make sure they w ill not drag on the
road when yo u are driving.
The chains shou ld cross under the tra iler
tongue to prevent it from dropping in case of
separat ion from the hitch .

Otherwise, the tongue load specified for
your vehicle will no longer be applicable.
Driving instructions
Driving with a trailer always requires extra
core and consideration.
T o obtain the best possible hand ling of vehicle
and trailer, please note the fo llowing:
.. Do not tow a loaded t railer when you r ca r it­
self is not loaded .
.. Be especially carefu l when passing other ve ­
hicles .
.. Observe speed limits.
.. Do not drive at the maximum permissible
speed .
.. Always apply brakes early .
.. Monitor the temperature gauge .
Weight distribut ion
T owing a loaded trailer with an empty car re ­
s ul ts 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 keep ing the trailer as light as possi­
ble under the ci rcumstances. Whenever poss i­
ble, transfer some cargo to the luggage com­
partment of the tow vehicle while obse rv ing
tong ue load requi rements and vehicle load ing
considerations .
Speed
The higher the speed, the more d ifficu lt it be­
comes for the driver to control the rig. Do not

204 Cleaning and protec tio n
Automatic car wash
The vehicle can be washed in almost any
modern automatic car wash .
The vehicle paint is so durable that the vehicle
can normally be washed without problems in
an automatic car wash. However, the effect on
the paint depends to a large extent on the de­
sign of the facility, the filte ring of the wash
water, the type of wash and care mater ial , etc.
I f the pa int has a dull appearance afte r going
through the car wash or is scratched, bring
this to the attention of the operator immedi­
ately. If necessary, use a different car wash.
Before going through a car wash, be sure to
take the usual precautions such as closing the
windows and power roof . Factory installed an­
tennas must not be removed.
I f you have installed additional accessor ies on
the vehicle - such as spoilers, roof rack, etc. -
it is best to ask the car wash operator if these
should be removed .
When driving through an automatic car wash,
fi rst se lect the N position and then switch the
engine off. If you switch the engine off when N is engaged, the transmission remains in N
for approximately 30 m inutes and then Pis
engaged.

246 Tires and wheels
& WARNING
Sudden tire failure can lead to loss of con­
trol, 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 hazard, 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 be ing 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 dam­
aged 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 .
