Airbag system -----------------=~-
& WARNING (continued )
• Always install forward or rear-facing child safety seats on the
rear seat -even with an Advanced Airbag Sy stem.
• If you must install a rearward -facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not appear and stay on,
immediately inst all the rear -facing child safety seat in a rear
seating position and have the airbag system inspected by your
authorized Audi dealer.
• A tight tether or other strap on a rearward-facing child restraint
attached to the front pas senger seat can put too much pressure
on the weight-sensing mat in the se at and reg ister more weight
than is actually on the seat. The heavier weight registered can make the system work as though an adult were on the seat and
deploy the Advanced Airbag when it must be suppressed causing
serious or even fatal injury to the ch ild .
• If, in exceptional circumstance s, you must install a forward ­
facing child restraint on the front passenger seat, always move the
seat into its rearmost position in the seat's fore and aft adjust ­
ment range , as far away from the airbag as possible . The backrest
must be adjusted to an upright position . Make sure that the
PASSENGER AIR BAG OFF light comes on and stays on all the time
whenever the ignition is switched on .
& WARNING
• If the PASSENGER AIR BAG OFF light does not go out when an
adult is sitting on the front passenger seat after taking the steps
described above, make sure the adult is properly seated and
restrained at one of the rear seating positions .
• Have the airbag sy stem inspected by your authorized Audi
dealer before transporting anyone on the front passenger seat .

& WARNING
Improper care , servicing and repair pro cedures can increase the
risk of personal injury and death by preventing an airbag from
deploying when needed or deploying an airbag unexpectedly :
• Never cover, obstruct, or change the steering wheel horn pad
or airbag cover or the instrument panel or modify them in any way .
• Never attach any objects such as cupholders or telephone
mountings to the surfaces covering the airbag units .
• For cleaning the horn pad or instrument panel , use only a soft ,
dry cloth or one moistened with pla in water . Solvents or cleaners
could damage the airbag cover or change the stiffness or strength
of the material so that the airbag cannot deploy and protect prop ­
erly .
• Never repair , adjust , or change any parts of the airbag system .
• All work on the steering wheel , instrument panel, front seats or

Trailer towing tips
Important to know
Your vehicle handles differently when towing a trailer because of
the additional weight and different weight distribution. Safety,
performance and economy will greatly depend on how carefully you
load your trailer and operate your rig.
Before you actually tow your trailer, practice turning, stopping and
backing up in an area away from traffic. Keep practicing until you
have become completely familiar with the way your vehicle -trailer
combination behaves and responds.
Backing up is difficult and requires practice. Backing up with a
trailer generally requires steering action opposite to that when
backing up your vehicle without a trailer.
Maintain a greater distance between your vehicle and the one in
front of you. You will need more room to stop. To compensate for
the trailer, you will need a larger than normal turning radius.
When passing, remember that you cannot accelerate as fast as you normally would because of the added load. Make sure you have
enough room to pass. After passing, allow plenty of room for your
trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane changes.
[ i] Tips
• Do not tow a trailer during the break-in period of your vehicle. • If you tow
a trailer, your Audi may require more frequent mainte­
nance due to the extra load~
page 401. •
Parking on a s1ope
Do not park on a slope with a trailer. If it cannot be
avoided , do so only after doing the following:
When parking:
-Apply the foot brake.
- Have someone place chocks under both the vehicle and
the trailer wheels.
- With chocks in place, slowly release 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.
- Start the engine.
- Move the selector lever to
D.
-Release the parking brake and slowly pull out and away
from the wheel chocks.
- Stop and have someone retrieve the wheel chocks.
[ i] Tips
I f you move the selector lever of the automatic transmission to P
before applying the parking brake and before blocking the wheels, II-

& WARNING (continu ed )
• Incorrect tire pressure and /or under inflation can cause
in creased tire wear and can affect the handling of the vehicle and
stopping ability .
• Incorrect t ire pressures and /o r underinflat ion can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing lo ss of vehicle control .
• The driver is respon sible for the correct tire pressures for all
tires on the vehicle. The applicable pre ssure values are located on
a sticker on the driver 's side 8-pillar or on the inside of the fuel
filler flap .
• Only when all tires on the vehicle are filled to the correct pres ­
sure , the tire pressure monitoring sy stem can work correctly .
• The use of incorrect tire pressure values can lead to accidents
or other damage . Therefore it is essential that the driver observe
the specified tire pressure value s for the tires and the correct pres ­
sures for the function of the tire pressure monitoring system.
• Always inflate tires to the re commended and correct tire pres ­
sure before driving off .
• Driving with underinflated tires bend more , letting them get
too hot resulting in tread separation , sudden tire failure and loss
of control.
• Ex cessive speed and /overloading can cause heat build-up ,
s udden tire failure and lo ss of control .
• If the tire pres sure is too low or too high , the t ires will wear
prematurely and the vehicle will not handle well .
• If the tire is not flat and you do not have to change a wheel
immediately , drive at reduced speed to the nearest service station
to check the t ire pressure and add air as required.

Changing a wheel
Before changing a wheel
Observe the following precautions for your own and your
passenger's safety when changing a wheel.
-After you experience a tire failure, pull the car well away
from moving traffic and try to reach
level ground before
you stop => & .
- All passengers should
leave the car and move to a safe
location (for instance, behind the guardrail)=> &.
- Engage the
parking brake to prevent your vehicle from
rolling unintentionally=> &. -
Move
selector lever to position P =:> & .
- If you are towing a trailer: unhitch the trailer from your
vehicle.
- Block the diagonally opposite wheel with the folding
chocks or other objects.
- Take the
jack and the inflatable spare tire out of the
luggage compartment=>
page 370.
& WARNING
You or your passengers could be injured while changing a wheel if
you do not follow these safety precautions:
• If you have a flat tire, move a safe distance off the road. Turn off
the engine, turn the emergency flashers on and use other warning
devices to alert other motorists.
• Make sure that passengers wait in a safe place away from the
vehicle and well away from the road and traffic.
• To help prevent the vehicle from moving suddenly and possibly
slipping off the jack , always fully set the parking brake and block
the wheel diagonally opposite the wheel being changed with the
folding chocks or other objects. When one front wheel is lifted off
the ground, placing the Automatic Transmission in "P" (Park) will
not prevent the vehicle from moving.
• Before you change a wheel, be sure the ground is level and firm .
If necessary, use a sturdy board under the jack.
• After installing the inflatable spare tire, make sure that you
replace the flat tire/wheel in its storage area properly and tighten
the knurled retaining screw securely. •

After changing a wheel
A wheel change is not complete without the doing the
following.
- Store and secure the wheel you replaced in the spare
wheel well.
- Replace the tools and the jack in their proper location.
- As soon as possible, have the
tightening torques on all
wheel bolts checked with a torque wrench. The correct
tightening torque is 120 ft lb (160 Nm).
- Have t he flat tire
replaced as soon as possible.
[ i] Tips
• I f you notice that the wheel bolts are corroded and difficult to

- Let the compressor run until it has reached 50 PSI (3.5
bar). Switch the compressor off after running for 8
minutes at the most -danger of overheating!
& WARNING
The compressor and the tire filler hose can become extremely hot
while they are running -danger of burns!
0 Note
Switch the compressor off after running for 8 minutes at the most -
danger of overheating! Allow the compressor to cool down for a few
minutes before you use it again.
[ i] Tips
The compressor must not be connected to the cigarette lighter
socket, as this socket does not provide the required power .•
Tires with unidirectional tread design
Tires with unidirectional tread design must be mounted
with their tread pattern pointed in the right direction.
Using a spare tire with a tread pattern intended for use
in a specific direction
When using a spare tire with a tread pattern intended for use in a
specific direction, please note the following:
• The direction of rotation is marked by an arrow on the side of the
tire.
• If the spare tire has to be installed in the incorrect direction, use
the spare tire only temporarily since the tire will not be able to
achieve its optimum performance characteristics with regard to
aquaplaning, noise and wear. •
We recommend that you pay particular attention to this fact
during wet weather and that you adjust your speed to match road
conditions.
• Replace the flat tire with a new one and have it installed on your
vehicle as soon as possible to restore the handling advantages of a
unidirectional tire. •
Notes on wheel changing
Please read the information => page 359, "New tires and replacing
tires and wheels " if you are going to use a spare tire which is
different from the tires on your vehicle.
After you change a tire :
• Check the tire pressure on the spare immediately after installa­
tion.
• Have the wheel bolt tightening torque checked with a torque
wrench as soon as possible by your authorized Audi dealer or a
qualified workshop.
• With steel and alloy wheel rims, the wheel bolts are correctly
tightened at a torque of 120 ft lb (160 Nm).
• If you notice that the wheel bolts are corroded and difficult to
turn while changing a tire, they should be replaced before you check
the tightening torque.
• Replace the flat tire with a new one and have it installed on your
vehicle as soon as possible. Remount the wheel cover.
Until then, drive with extra care and at reduced speeds .
& WARNING
• If you are going to equip your vehicle with tires or rims which
differ from those which were factory installed, then be sure to read
the information
=> page 359, "New tires and replacing tires and
wheels". ..
