For your own safety and to reduce the risk of in­
jury in the event of an accident, we recommend
that you adjust the driver's seat to the following
position :
,.. Adjust the driver's seat so that you can easily
push the pedals all the way to the floor wh ile
k eeping your knee(s) s lightly bent
c:> .&_ .
,.. Adjust the angle of the seatback so that it is in
an upright position so that your back comes in
full contact with it when you drive.
,.. Adjust the steering wheel so that there is a dis ­
tance of at least 10 in (25 cm) between the
steering wheel and your breast bone
c:> fig. 150.
If not possible, see your authorized Audi deal­
ersh ip about adaptive equipment .
,.. Adjust the steering wheel so that the steering
whee l and airbag cover points at you r chest and
not at your face.
180
,.. Grasp the top of the steering wheel with your
elbow(s) slightly bent.
,.. Fasten and wear safety belts correctly
c:> page 190 .
,.. Always keep both feet in the footwell so that
you are in control of the vehicle at all times .
For detailed information on how to adjust the
driver's seat, see
c:> page 46, Front seats.
A WARNING
Drivers who are unbelted, out of position or
too close to the airbag can be seriously in -
ju red by an airbag as it unfolds. To help re-
duce the risk of serious pe rsonal injury:
-Always adjust the driver's seat and the
steer ing wheel so that the re are at least
10 in (25 cm) between your breastbone and
the steering wheel.
-Always adjust the driver's seat and the
steer ing whee l so that there are at least 4 in
(10 cm) between the knees and the lower
pa rt of the instrument pane l.
- Always hold the steering wheel on the out­
side of the steering wheel rim with your
hands at the 9 o'clock and 3 o'clock posi­
tions to help reduce the risk of personal in­
jury if the dr iver's a irbag inflates.
- Never hold the steering wheel at the
12 o'clock position or with your hands at
other positions inside the steering whee l
rim or on the steering wheel hub . Holding
the steering wheel the wrong way can cause
serious injuries to the hands, arms and head
if the driver's airbag inflates
- Pointing the steering wheel toward your face decreases the ability of the supplemen­
tal driver's airbag to protect you in a coll i­
sion.
- Always sit in an upright pos it ion and never
lean against or place any part of your body
too close to the area where the airbags are
located.
- Before driving, always adjust the front seats
properly and make sure that all passengers
-
are properly restrained . ..,.

Safe driving
on the safety compliance sticker on the left
door jamb. Exceeding permissible weight
standards can cause the vehicle to slide and handle differently .
- Please observe information on safe driving
9 page 179.
A WARNING
To help prevent poisonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed while driving.
- Never transport objects larger than those
fitting completely into the luggage area be­ cause the rear lid cannot be fully closed .
- If you absolutely must drive with the rear lid open, observe the following notes to reduce
the risk of poisoning:
- Close all windows,
- Close the convertible top,
- Open all air outlets in the instrument pan-
el,
- Switch off the air recirculation,
- Set the fresh air fan to the highest speed .
A WARNING
.
-
Always make sure that the doors, all win­
dows, the convertible top and the rear lid are
securely closed and locked to reduce the risk
of injury when the vehicle is not being used.
- After closing the rear lid , always make sure
that it is properly closed and locked.
- Never leave your vehicle unattended espe­
cially with the rear lid left open . A child
could crawl into the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out. Be­
ing trapped in a vehicle can lead to serious
personal injury.
- Never let children play in or around the vehi­
cle.
- Never let passengers ride in the luggage compartment. Vehicle occupants must al­
ways be properly restrained in one of the ve­
hicle's seating positions.

@ Tips
- Air circulation helps to reduce window fog­
ging. Stale air escapes to the outside
through vents in the trim panel, on the left
side of the luggage compartment. Be sure
to keep these slots free and open.
- The tire pressure must correspond to the
load. The tire pressure is shown on the tire
pressure label. The tire pressure label is lo­
cated on the driver's side B-pillar . The tire
pressure label lists the recommended cold
tire inflation pressures for the vehicle at its
maximum capacity weight and the tires that
were on your vehicle at the time it was man­
ufactured. For recommended tire pressures
for normal load conditions , please see chap­
ter ¢page255.
Tie -downs
The luggage compartment is equipped with four
tie-downs to secure luggage and other items.

In a collision, the laws of physics mean that even
smaller items that are loose in the vehicle will
become heavy missiles that can cause serious in­
jury. Items in the vehicle possess energy which
vary with vehicle speed and the weight of the
item . Vehicle speed is the most significant factor.
For example , in a frontal collision at a speed of
30 mph (48 km/h), the forces acting on a 10 lbs
(4.5 kg) object are about 20 times the normal
weight of the item. This means that the weight
of the item would suddenly be about

-Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
Aud i.
- Never use add itiona l seat cushions that
cover the areas where the s ide airbags in­
flate.
- Damage to the origina l seat covers or to
the seam in the area of the side airbag module must always be repaired immedi­
ately by an authorized Audi dealer.
- The airbag system can deploy only once . Af­
ter an airbag has been deployed, it must be
rep laced with new rep lacement parts de­
signed and approved especially fo r you r
Audi mode l version. Replacement of com­
plete airbag systems or airbag components
must be performed by qualified workshops
only . Make sure that any airbag service ac­
tion is entered in your Audi Warranty
&
Maintenance booklet under AIRBAG RE­
PLACEMENT RECORD.
- For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechn ic circuit
interrupter.
-Work on the pyrotechnic circu it interrupt­
er must only be performed by a qualified
technicians who have the experience, in­
formation and special tools necessary to perform the work safely.
-If the vehicle or the circuit interrupter is
scrapped, all app licab le safety precautions
must be followed.

Airbag syste m
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash. For example, using tire-rim
combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension, including the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic cont rol u nit. Some suspension c hanges
can, for example, increase the fo rce leve ls meas­
u red by the sensors and make t he a irbag system
deploy in crashes in which it wou ld not deploy if
the changes had not been made. Other kinds of
changes may reduce the force levels measured by
the sensors and prevent the a irbag from deploy­
ing when it should.
A WARNING
-
Changing the vehicle's suspension including use of unapproved tire-rim combinations can
change Advanced Airbag perfo rmance and in­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
ter istics as the components o riginally instal­
led on your vehicle .
-Never use tire-rim combin ations that have
not been approved by Audi .

General information
~check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob ­
jects from the tire tread.
~ If driving over curbs or similar
obstacles, drive slowly and ap­ proach the curb at an angle.
~Have faulty tires or rims re­
placed immediately.
~ Protect your tires from oil,
grease and fuel.
~ Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
~Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
_&. WARNING -
-Never drive faster than the maximum permitted speed
for your tires. This could cause
the tires to heat up too much.
This increases the risk of an
accident because it can cause
the tire to burst .
-Always adapt your driving to the road and traffic condi-
244
tions . Drive carefully and re­
duce your speed on icy or slip­
pery roads . Even winter tires
can lose traction on black ice.
(@ Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
i n those seasons . Aud i recom­
mends using winter tires dur­
ing the winter months . Low
temperatures significantly de­
crease the elasticity of summ­
er 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
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be used in winter driving condi­
t ions. The surface of the r ims
does not have sufficient corro­
sion protection for this and
could be permanently dam ­
aged by road salt or similar
substances.
