pressure label lists the recommended cold tire inflation pressures
for the vehicle at its maximum capacity weight and tires that were
on your vehicle at the time it was manufactured.
If you wish to improve comfort when operating the vehicle at
normal load (up to 3 occupants), you can adjust tire pressures to
those specified for normal vehicle load. Before operating the vehicle
at maximum load , you must increase the tire pressures to those
specified for maximum vehicle load
=> &.
Bear in mind that the tire pressure monitoring system* can only
monitor the tire pressures you have stored. The system does not
recognize the load condition of your vehicle .
The effec tiveness of the tire pressure mon itoring system* will be
impaired if you store normal load pressures but then operate the
vehicle at its maximum load=>&. See the
illustration=>
page 330, fig. 274 for the location of the label
either o n driver's side 8-pillar or inside the fuel filler flap (color of
the actual label and exact location on the vehicle will vary slight ly).
Note that the following tab le is accurate at the time of going to
press and is subject to change. In the event of discrepancies, the t ire
pressure label (On USA vehicles, the tire pressure label is located on
the driver's side 8-pillar. On Canada vehicles, the tire pressure label
is located either on the driver 's side 8-pillar or inside the fuel fil ler
flap) always takes precedence.
The table below lists the recommended cold tire inflation pressures
for the Audi mode l covered by your Owner's Literature at the
vehicle's capacity weight and the tire sizes installed on the respec­
tive models as original equipment, or as a factory option.

& WARNING (continued )
front wheel is lifted off the ground , placing the Automatic Trans­
mission 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 spare wheel, make sure that you replace the
flat tire/wheel in its storage area properly and tighten the knurled
retaining screw securely.
[ i J Tips
Before changing the wheel, you must activate the jacking mode, so
that the automatic controls for the Adaptive Air Suspension do not
make it more difficult to lift the vehicle with the jack =>
page 791. •
Changing a wheel
When you change a wheel, follow the sequence described
below step-by-step and in exactly that order.
1. Activate the vehicle jacking mode~ page 191.
2. Remove the decorative wheel cover*. For more details
see also
~ page 355, "Decorative wheel covers" or
~ page 355, "Wheels with wheel bolt caps" .
3. Loosen the
wheel bolts ~ page 356.
4. Locate the proper mounting point for the jack and align
the jack below that point~
page 356.
5. Lift the car with the jack~ page 356.
6. Remove the wheel with the flat tire and then install the
spare
~ page 358 .
7. Tighten all wheel bolts lightly. 8.
Lower the vehicle with the
jack.
9. Use the wheel bolt wrench and
firmly tighten all wheel
bolts
~ page 356.
10. Replace the decorative wheel cover*.
11. Deactivate the vehicle jacking mode~ page 191.
& WARNING
Always read and follow all WARNINGS and information :::::> 6 in
" Raising the vehicle" on
page 356 and => page 359. •
After changing a vvheel
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.
- Check the
tire pressure on the spare wheel immediately
after mounting it.
- As soon as possible , have the
tightening torques on all
wheel bolts checked with a torque wrench. The correct tightening torque is 90 ft lb (120 Nm) .
- Have the flat tire
replaced as soon as possible.
[ i J Tips
• 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. .,_

Taking the wheel off/installing the spare
Follow these instructions step-by-step for changing the
wheel
Fig . 291 Changing a
wheel: using the
screwdriver handle
!with the blade
removed) to turn the
bolts
Fig . 292 Changing a
wheel: alignment pin
inside the top hole
After you have loosened all wheel bolts and raised the
vehicle off the ground, remove and replace the wheel as
follows:
Removing the wheel
-Use the hexagonal socket in the screwdriver handle to
completely remove the topmost wheel bolt and set it
aside on a
clean surface => fig. 291. -
Screw the threaded end of the
alignment pin from the
tool kit hand-tight into the empty bolt hole=> fig. 292.
- Then remove the other wheel bolts as described above .
- Take off the wheel leaving the alignment pin in the bolt
hole.
Putting on the spare wheel
- Lift the spare wheel and carefully slide it over the align­
ment pin to guide it in place.
- Use the hexagonal socket in the screwdriver handle to
screw in and tighten all wheel bolts
slightly.
- Remove the alignment pin and insert and tighten the
remaining wheel bolt slightly like the rest.
Turn the jack handle counter-clockwise to lower the
vehicle until the jack is fully released.
- Use the wheel bolt wrench to tighten all wheel bolts
firmly=>
page 356. Tighten them crosswise, from one
bolt to the (approximately) opposite one, to keep the
wheel centered.
[ i ] Tips
Never use the hexagonal socket in the handle of the screwdriver to
loosen or tighten the wheel bolts.
• Pull the reversible blade from the screwdriver before you use the
hexagonal socket in the handle to turn the wheel bolts.
• When mounting tires with
unidirectional tread design make sure
the tread pattern is pointed the right way=>
page 359.
• The wheel bolts should be clean and easy to turn. Check for dirt
and corrosion on the mating surfaces of both the wheel and the .,,_

Bulbs
Replacing light bulbs
For your safety, we recommend that you have your autho­
rized Audi dealer replace burned out bulbs for you.
It is becoming increasingly more and more difficult to replace
vehicle light bulbs since in many cases, other parts of the car must
first be removed before you are able to get to the bulb. This applies
especially to the light bulbs in the front of your car which you can
only reach through the engine compartment.
•
Sheet metal and bulb holders can have sharp edges that can cause
serious cuts, and parts must be correctly taken apart and then prop-.,

& WARNING
Contact with high-voltage components of the ele ctri cal system
and improper replacement of gas discharge (Xenon) headlight
bulbs can cause ser ious personal injury and death .
• Xenon bulbs are pressurized and can explode when being
changed .
• Changing Xenon lamps requires the special training, instruc ­
tions and equipment .

Batteries contain electricity , acid , and gas . Any of these can cause
very serious or fatal injury. Follow the instructions below for safe
handling of your vehicle 's battery .
• Always shield your eyes and avoid leaning over the battery
whenever possible .
• A discharged battery can freeze at temperatures just below
32 °F (0 °C l. Before connecting a jumper cable , you must thaw the
frozen battery completely , otherwise it could explode.
• Do not allow battery a cid to contact eyes or skin . Flush any
contacted area with water immediately.
• Improper use of a booster battery to start a vehicle may cause
an explosion.
• Vehicle batteries generate e xplosive gases . Keep sparks, flame
and lighted cigarettes away from batteries.
• Do not try to jump start any vehicle with a low ac id level in the
battery.
• The voltage of the booster battery must also have a 12-Volt
rating . The capacity (Ahl of the booster battery should not be
lower than that of the discharged battery . Use of batteries of
different voltage or substantially different "Ah " rating may cause
an e xplosion and personal injury .
• Never charge a frozen battery. Gas trapped in the ice may cause
an explosion .
• Never charge or use a battery that has been frozen . The battery
case may have be weakened.
• Use of batteries of different voltage or substantially different
capacity (Ah ) rating may cause an explosion and injury . The
capacity (Ahl of the booster battery should not be lower than that
of the discharged battery . .,_
