Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi. Installing,
removing, servici ng or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a co llision.
There are some important th ings you have to
know to make sure that the effect iveness of
the system will not be impa ired and that dis­
carded components do not cause injury or po l­
lute the env ironment.
_& WARNING
Improper ca re, 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 unexpected ly:
- Never cover, obstr uct, o r change the
steering wheel horn 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 units.
- For cleaning the horn pad or instrument
pane l, use only a soft, dry cloth or one
moistened w ith plain water. Solvents or
cleaners co uld damage the airbag cover
o r change the stiffness or strength of the
material so tha t the airbag cannot de­
ploy and protec t prope rly.
- Never repa ir, adjust, or change any par ts
of the airb ag sys tem.
- All wo rk on the stee ring wheel, inst ru­
ment pane l, front seats or electrical sys­
tem (incl uding t he inst allation of aud io
equipment, cellular telephones and CB
radios, etc.) must be performed by a
qualified technician who has the training
and special equipment necessary.
A irbag system 197
-For any work on the airbag system, we
strongly recommend that yo u see your
author ized Audi dealer or qualif ied 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 upholstery over the fron t seat­
backs tha t have not been specifically
approved by Audi.
- Never use addi tional seat cushions that
cover the areas where the side a irbags
i nflate.
- Damage to the orig inal seat cove rs 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
deale r 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
men t pa rts designed and approved espe­
cially fo r you r A udi model version. Re­
placemen t of complete airbag systems
or airbag components mus t be per ­
formed by qualified workshops on ly .
Make sure that any airbag serv ice action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- For safety reasons in severe accidents,
the alte rnator and starter are sepa rated
from the veh icle battery with a pyrotech­
nic circuit inte rrupte r.
- W ork on the pyrotechnic c ircuit inter ­
rupter m ust only be pe rformed by a
qualified dea le r - risk of an accident!
- If the vehicle or the circuit interr upter
is scrapped, all applicable safety pre­
cautions must be fo llowed.

A WARNING 1-=
-ESC, ABS, ASR and EDL cannot overcome
the laws of physics. This is espec ially im­
portant on slippery or wet roads. If the
systems begin act ing to stab ilize your ve­
hicle, you should immediately change
your speed to match the road and traffic conditions. Do not let the increased sa fe­
ty provided by these systems tempt you
to take r isks. Doing so will increase the
risk of a loss of vehicle control, collision
and ser ious persona l injuries.
- Always adapt your speed to road, traffic
and weather conditions. The risk of los­
ing control of the vehicle increases when
dr iv ing too fast, especially through
curves and on slippery or wet roads, and
w hen driving too close to vehicles up
ahead. ESC, ABS, the b rake assist sys­
tem, ASR and EDL cannot prevent co lli­
sions.
Switching on/off --- -
Intellig ent technolog y 225
-Always accelerate with special care on
even, smooth surfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these assistance systems that cannot al­
ways he lp to reduce the risk of loss of ve­
hicle control.
@ Tips
- ABS and ASR only work correctly when
all four wheels are equipped with identi­
cal tires. D iffe rent tire sizes can lead to a
reduction in engine powe r.
- Yo u may hear noises when the systems
descr ibed are working.
- If the ind icator light
DJ or ~ (USA
mode ls)/ ii] (Canada models) appears,
there may be a malfunction~

The fo llow ing situations are exceptions where
it may be useful to switch on offroad mode to
allow the whee ls to spin: -
Rocking the vehicle to free it when it is stuck
- Dr iving in deep snow or on loose ground
- Driving with snow chains
- Dr iving on roug h terrain when much of the
car's weight is lifted off the whee ls (ax le ar ­
ticu lation)
- Dr iving downhi ll wh ile braking on loose

have become completely familiar with the way
your vehicle-trailer combination behaves and responds.
Backing up is difficu lt and requires practice.
Backing up with a trai ler genera lly requires
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
more 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 tra iler before chang­
ing lanes again .
Avoid jerky starts, sharp turns or rapid lane
changes.
@ Tips
- Do not tow a traile r during the break-in
period of your vehicle.
- If you tow a trailer, your A udi may re­
quire more frequent maintenance due to
the extra load
<=> page 316.
Parking on a slope
Do not park on a slope with a trailer. If it can­
not be avoided, do so only after 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 place, slowly re lease the
brakes until the wheel 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.
Trailer towing 243
.. 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 retr ieve 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
whee ls, you may have to use more force
l ater to move the lever out of the
P posi­
tion.

wall.
The correct tire pressure for the spare wheel is
located on a label on the driver's side 8-p illar .
Because technical changes may be made to
vehicle equipment 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 your vehicle. Make sure that the tire
size info rmation on the vehicle label is the
same as the size of the tires 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
vehicle as a previously owned vehicle.
Remember, your safety and that of yo ur pas­
sengers also depends on making s ure that load
limits are not exceeded . Veh icle load in­
cludes everybody and eve ryth ing in and on the
vehicle. These load limits are techn ica lly refer­
red to as the veh icle's Gross Vehicle Weight
Rating ("GVWR"). The Gross Axle We ight Rat­
ing ("GAWR") is the maximum load that can
be applied at each of the vehicle's two ax les.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating are listed on the
safety comp liance sticker label located on the
driver's side 8-pillar . The tire pressure label on
your Audi lists the maximum combined
weight of all of the occupants and luggage or
other cargo that the veh icle can carry . For the
location of the tire pressure label¢
fig. 249. ..,_

-If the ti re is not flat and y ou do not have
to change a wheel immed iate ly, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required.
(D Note
Dr iving without va lve stem caps can cause
damage to the t ire va lves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are secu re ly
mounted on the va lve.
@) For the sake of the environment
Underinflated tires will a lso increase the
fue l consumption.
Tires and vehicle load limits
There are limits to the amount of load or
weight t hat any veh icle and any t ire ca n car ry.
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overload ing
can not on ly lead to loss of vehicle contro l,
but can a lso damage important parts of the
vehicle and can lead to sudden tire failure, in­
cluding a blowout and sudden deflation that
can cause the ve hicle to crash.
Your safety and that of yo ur passenge rs a lso
depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everyth ing in and on the vehicle. These
load limits a re tech nica lly referred to as the
ve hicle's
Gross Veh icle Weight Rating
("GVWR").
The "GVWR" includes the we ight of the basic
ve hicle, all factory installed accessories, a full
tank of f uel, oil, coo lant and othe r fluids plus
max imum load. The maximum load includes
the number o f passenger s that the ve hicl e is
intended to carry ("se ating capacity") w it h an
assumed weig ht o f 150 lbs (68 kg) for each
passenger at a designated seating position
and the tota l weight of any luggage in the ve­
h icle. If you tow a trailer, the weight of the
trailer hitch and the tong ue weight of the
Tire s an d wheel s 281
loaded tra ile r must be included as part of the
vehicle load .
T he
Gro ss Ax le Weight Rating (" GAWR") is
the max imum load th at can be applied at each
of the vehicle's two axles .
T he Gross Vehicle Weight Rat ing and t he
G ross Ax le Weig ht Ra ting are l iste d on the
s af ety comp liance s tic ke r la bel lo cated on the
driver's side 8 -pillar . Your Audi has 5 seating
positions, 2 in the front and 3 in the rear fo r
total seating capacity of 5. On vehicles with
s ix seats*, your vehicle has two front seats,
two seats in the second row seat ing and two
seats in the th ird row seati ng. On veh icles
with seven seats*, your vehicle has two front
seats, t hree seats in the second row s eating
and two seats in t he third row seating. Ea ch
seat ing pos itio n has a se at belt
~page 174,

The fact that ther e is a n upper limit to you r
vehicle's G ross Vehicle Weigh t Rati ng means
that the to tal weig ht of whatever is bei ng car­
ried in the vehicle ( in cl ud ing the weight of a
trailer hitch and the tongue weight of the l oa ded trai le r) is limite d. The more passen­
gers in the vehicle or passengers who are heavier than the standard we ights assumed
mean that less we ight can be carried as lug­

292 Tires and wheels
TPMS malfunction indicato r is combined with
the low tire pressure telltale . When the sys­
tem detects a malfunct ion, the te lltale will
flash for approximately one minute and then
remain continuously illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low t ire pressure as intended. TPMS
malfunctions may occur for a variety of rea­
sons, includ ing the installat ion of replace­
ment or alt ernate tires or wheels on the vehi­
cle that prevent the TPMS from functioning
properly. Always check the TPMS malfunct ion
tellta le after replacing one or more tires or
wheels on your vehicle to ensure that the re­ p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
Fig. 254 D isplay: underinflat ion wa rning
Using the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum­
ference and vibration characteristics of the in­
dividual tires. If the pressure decreases in one
or more tires, this is indicated in the instr u­
ment cluster with a
[D] warning symbol and a
message ¢
fig. 254. The driver message in the
display goes out after S seconds. The driver
message can be displayed again by pressing
the
! CHECK I button . If only one tire is affect­
ed, the display will indicate its position . The tire pressure
monitoring must be reset via
MMI each time the pressures are adjusted (e.
g. when switching between partial and full
load pressure) or after changing or replacing a
tire on your vehicle¢
page 293. The TPMS in­
dicator on ly monitors the tire pressure that
you have prev iously stored . You can find the
re commended t ire pressures for your vehicle
on the label on driver's s ide B-pillar
¢page 277.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the t ire pressure in one or more tires is too
low,
- the t ire has structural damage,
- the t ire pressure was changed, wheels rotat-
ed or replaced but the TPMS was not reset

Attempt to store the correct tire pressure
¢
page 293. If the indicator light does not
turn off or if it turns on shortly thereafter, im­
med iate ly drive your vehicle to a n author ized
Audi dealer or authorized repair facility to
have the malfunction corrected.
.&_ WARNING
- If the tire pressure indicato r appears in
th e ins trum ent cluster display, one or
more of your tires is significantly under­
inflated . Reduce your speed immediately ..,_

and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures. In·
flate the tire pressure to the proper pres­
sure as indicated on the vehicle's tire
pressure label ¢
page 2 77. Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor indi­
cator may be delayed.
- Ask your authorized Audi dealer if run­
flat tires may be used on your vehicle.
Your vehicle registration becomes invalid
if you use these tires when not permit­
ted. Damage to your vehicle or accidents could also result.
@ Tips
- The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction.
- Using snow chains may result in a system
malfunction.
- The tire pressure monitoring system on
your Audi was developed using tires with
the "AO" or "RO" identification on the
tire sidewall¢
page 284. We recom­
mend using these tires.
Reset tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro­ tated or changed, the TPMS must be reset via
MMI.
.,. Before resetting the TPMS, the current pres ­
sures of all four tires must correspond to
the specified values. Adjust the tire pressure and reset the pressure in the tire pressure
