you cannot maintain this minimum dis­
tance, the airbag system cannot protect
you properly.
- If physical limitations prevent you from
sitting 10 inches (25 cm) or more from
the steering wheel, check with your au­
thorized Audi dealer to see if adaptive
equipment is available.
- If the steering wheel is aligned with your
face, the supplemental dr iver's a irbag
cannot provide as much protection in an
accident. Always make sure that the

Repair, care and disposal of the airbags
Parts of the a irbag system are installed at
many different places on your Audi. Installing,
removing, serv icing o r repairing a part in an
area of the vehicle can damage a part o f an
ai rbag system and prevent that system from
working properly in a co llision.
There are some important things you have to know to make sure that the effect iveness of
the system will not be impai red and that dis­
carded components do not cause injury or po l­
lute the environment.
A WARNING
-Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag from deploy ing when needed or deploying
an airbag unexpectedly:
- Never cover, obstruct, or change the steering wheel ho rn pad or airbag cover
or the instrument pane l or modify them
in any way .
- Never attach any objects such as cu­
pholders or telephone mountings to the
surfaces covering the airbag uni ts.
- For cleaning the horn pad or instrument
pane l, use only a soft, d ry clo th or one
moistened w ith plain water. Solvents or
cl eaners co uld damage the airbag cover
or change the stiffness o r strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repa ir, adjust, or change any parts
of the airbag system.
- All wo rk on the stee ring wheel, inst ru ­
ment pane l, front seats or electrical sys­
tem (incl uding the installation of aud io
equipment, cellular telephones and CB
A irbag system 193
radios, etc.) must be performed by a
qualif ied technic ian who has the training
and specia l equipment necessary.
- For any work on the airbag system, we
strongly recommend that yo u see your
authorized Audi dealer or qualified work­
shop.
- Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the s ide a irbag
can inflate without interference:
- Never install seat covers or rep lace­
ment upholste ry over the front se at­
backs tha t have not been specifically
approved by Audi.
- Never use addi tional seat c ushions that
cover the areas where the side ai rbags
inflate.
- Damage to the orig inal seat covers or
to the seam in the area of the side ai r­
bag module must a lways be repaired
i mmediately by an author ized Audi
dealer.
- The airbag system can be activated only
once . After an airbag has inflated, it
must be replaced by an authorized Aud i
dea ler or qualified technician who has
the technical information, training and
specia l equipment necessary .
- The airbag system can be deployed only once . After an airbag has been deployed,
it must be replaced with new replace­
ment pa rts designed and approved espe­
cially fo r you r A udi model version . Re­
placement of complete airbag systems
or airbag components must be pe r­
formed by qualified workshops on ly .
Make sure that any airbag serv ice action

238 Trailer towing
your vehicle-trai ler combination behaves and
responds.
Backing up is difficult and requires practice.
Backing up with a trailer genera lly requi res
steering action opposite to that when backing
up your vehicle without a trailer .
Maintain a greater distance between your ve­
hicle and the one in front of you. You will need
mo re room to stop. To compensate for the
trai ler, you will need a larger than norma l
turning radius.
When passing, remember that you cannot ac ­
celerate as fast as you normally would be­
cause of the added load. Make sure you have
enough room to pass. After passing, allow
plenty of room for your trai ler before chang ­
ing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, you r A ud i may re­
quire more frequent maintenance due to
the extra load
~page 319.
Parking on a slope
Do not pork on a slope with a trailer. If it can­
not be avoided , do so only ofter doing the fol­
lowing:
When parking:
.. Apply the foot brake .
.. Have someone place chocks under both the
vehicle and the trai ler wheels .
.. With chocks in p lace, slowly re lease the
brakes until the whee l chocks absorb the
load .
.. Turn the wheels towards the curb .
.. Apply the parking brake .
.. Move the selector lever to
P.
When restarting after parking:
.. Apply the foot brake .
.. Start the engine. ..
Move the selector lever to
D.
.. Release the parking brake and s low ly pull
out and away from the wheel chocks .
.. Stop and have someone retrieve the wheel
chocks .
(D Tips
If you move the selector lever of the auto­
matic transmission to
P before applying
the parking brake and before blocking the
wheels, you may have to use more force later to move the lever out of the
P posi­
tion.

XL= reinforced or extra load tire. It may also appear as xl, EXTRA LOAD, or RF on the tire side­
wall.
The correct tire pressure for the spare wheel i s
l ocated on a label on the driver's side 8-pilla r.
Because technical changes may be made to
vehicle equ ipment dur ing the model year , al­
ways compare the tire size designation on the
tire pressure label on your vehicle w ith the
tires on you r vehicle. Ma ke su re that the tire
si ze information on the ve hicle label is the
same as the s ize of the t ires on the vehicle.
This is especially important if the vehicle be­ l ongs to someone else or you bought the vehi­
cle with different rims/tires or you bought the
ve hicle as a previously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on making sure that
l oad limits are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
vehicle. These load limits are technically refer­ red to as the vehicle's Gross Vehicle We ight
Rating ("GVWR") . The Gross Axle Weight Rat­
i ng ( "GAWR") is the maximum load that can
be appl ied at each of the veh icle's two axles.
The G ross Vehicle Weight Rating and the Gross Axle Weig
ht Rating are listed on the
safety comp liance sticker label located on the
drive r's side 8-pillar . The tire pressure labe l on
yo ur A udi lists t he maxim um combined
weight of all o f the occ upants and luggage or
othe r cargo that t he vehicle can carry. Fo r the
location of the tire press ure label ¢

A WARNING
Overloading a vehicle can cause loss of ve­
h icle control, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more we ight than your veh icle
was des igned to carry will prevent the
veh icle from handling properly and in­
crease the risk of a loss of vehicle con­
trol.
- The brakes on a vehicle that has been overloaded may not be able to stop the
veh icle w ith in a safe distance.
- T ires on a vehicle that has been overload ­
ed can fail suddenly ca using loss of con-
trol and a crash . ..,.

pressure label lists the recommended cold
tire i nflatio n pressures for the vehicle at its
maximum capacity we ight a nd the tires that
were on your vehicle at the time it was man ­
ufactured . For recommended t ire pressures
for normal load condit ions, please see chap ­
ter ~
page 2 78 .
-Turn the valve stem cap counter-clockwise
to remove it from the tire valve .
- Place the air pressure gauge on the valve.
- The tire pressures should only be checked
and adjusted when the tires are cold . The
s light ly raised pressures of warm tires must
not be reduced .
- Adjust the tire pressure to the load you are
carrying.
- Re insta ll the va lve stem cap on the valve .
When should I check the tire pressure ?
The correct tire pressure is especially impor ­
tant at high speeds . The pressure sho uld
therefo re be checked at least once a month
and a lways before start ing a journey. Do not
forget to check the tire pressure for the spare
wheel.
When should I adju st the tire pre ssures?
Ad just the tire pressure to the load you are
carrying. After changing a wheel
or replacing
wheels you have to adjust the tire pressures
on all wheels. In addition, you must then
store the new tire pressures i n the t ire pres­
sure mon itor ing system
~ page 294.
A WARNING
Incorrect tire pressures and/or unde rinfla­
tion ca n lead sudden tire failure, loss of
cont ro l, col lision, ser ious persona l inju ry
or even death.
- Whe n the wa rning symbo l
RI] appears in
the instrument cl uster, s top an d inspect
the tires.
- Incorre ct tire pressure and/or unde rinfla­
t ion can cause inc reased t ire wear and
can affect the handling o f the veh icle and
stopp ing ability.
- Incorrect tire pressures and/or underin­
flation can also lead to sud den tire fa il-
Tires an d wheel s 281
ure, including a blowout and sudden de­
flation, ca using loss of veh icle contro l.
- The driver is responsib le for the correct
tire pressures for all tires on the veh icle.
The applicable pressure values are locat­
ed on a sticker o n the dr iver's s ide B-pil­
lar .
- Onl y when all tires on the vehicle are fil­
led to the correct pressure, the t ire pres­
sure mon itor ing system can work cor­
rectly .
- The use of incorrect tire pressure va lues
can lead to acc idents or other damage .
Therefore it is ess ential that th e drive r
observe t he spec ified t ire p ress ure val ues
for the tires and the cor rect pressures for
the func tion of the t i re p ress ure moni to r­
ing system.
- Always in flate tires to the recommen ded
a nd correct t ire p ress ure be fore dr iv ing
off .
- D riving with unde rinf lated tires bend
mo re, letting them get too hot resulting
in tread separation, s udden tire failure
and loss of control.
- Excessive speed and/overloading can
cause heat b uild- up, sudden tire failure
and loss of control.
- If the tire pressure is too low or too high,
the t ires will wear prematurely and the
veh icle w ill not handle well.
- If the tire is not flat and you do not have
to change a wheel immediately, d rive at
red uced speed to the nearest service sta­
tion to check the t ire press ure and add
air as requ ired .
(D Note
Driving w ithout valve stem caps can cause
damage to the tire valves. To prevent this,
a lways make sure that factory installed
valve s tem caps o n all whee ls are sec urely
mounted o n the valve .
@ For the sake of the environment
Underinflated tires will also increase the
fuel consumpt ion.
