Emergency assistance
& 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 ti re, move a safe d ista nee
off the road . Turn off the engine, turn the
emergency flashers on and use other warn·
ing 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 front and back of 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 .
- Always store the vehicle tool kit, the jack
and the replaced tire in the luggage com­
partment
c:> page 102 .
(D Tips
Obey all laws.
Changing a wheel
When you change a wheel, follow the sequence
described below step-by-step and in exactly that
order.
1. Remove the decorative wheel cover* or the
wheel bolt caps*. For more details see also
<=:>page 193.
2. Loosen the wheel bolts c:> page 193.
3. Locate the proper mounting point for the
jack and align the jack below that point
<=:>page 194.
4. Lift the car with the jack c:> page 194 .
5. Remove the wheel with the flat tire and then
install the
spare tire <=:>page 195.
6. Tighten all wheel bolts lightly.
7.
Lower the vehicle with the jack.

8. Use the wheel bolt wrench and firmly tighten
all wheel bolts in a crisscross pattern
<=:>page 193.
9. Replace the decorative wheel cover* or the
wheel bolt caps*.
& WARNING
Always read and follow all WARNINGS and in­
formation
c:> .&. in Raising the vehicle on
page 194
and <=:>page 196.
After changing a wheel
A wheel change is not complete without the do·
ing the following .
.,. Always store the vehicle tool kit, the jack* and
the replaced tire in the luggage compartment
c:>page 102.
.,. Check the tire pressure of the spare tire as soon
as possible .
.,. As soon as possible, have the
tightening tor·
ques
on all wheel bolts checked with a torque
wrench. The correct tightening torque is
10S ft lbs (140 Nm).
.,. Have the flat tire
replaced as soon as possible.
(D Tips
- If you notice that the wheel bolts are cor­
roded and difficult to turn while changing a
tire, they should be replaced before you check the tightening torque.
- Drive at reduced speed until you have the
tightening torques checked .

Emerg ency assis ta nce
Raising the vehicle
The vehicle must be li~ed with the jack first be­
fore the wheel can be removed .

,.. Activate the pa rking brake to prevent the vehi­
cle from rolling unintentionally .
,.. Move the selector lever to the P position.
,.. Find the
m arki ng (imprint) on the sill that is
nearest the wheel that will be changed
c> fig . 152. Behind the marking, there is a li ft ­
ing po int
on the sill for the vehicle jack.
• Turn the
veh icle jack located under the lifting
point on the s ill to ra ise the jack until the
jaw @¢
fig. 153 covers the notch on the veh i­
cle ¢
.&_, ¢(D .
,.. Align the vehicle jack so the jaw @covers the
notch and the base plate @ is flat on the floor .

actly
one l ocation fo r each wheel. The jack must
not be positioned at any other location
c> & ,
¢(I) .
So ft ground
under the jack can cause the vehicle
to slip off the jack . Always place the jack on firm
ground . Use a flat, stable support if necessary.

sl ippery su rf ace such as tile.
A WARNING
-
- You or your passengers could be injured
while changing a wheel if you do not follow
these safety precautions:

cause an injury if it does not have suffi­
cient hold on the vehicle.
- Use only the jack* supplied with your vehi­ cle to raise the vehicle. If you use a jack
from a different vehicle, your vehicle may
slip off the jack - risk of injury!
- Do not use the jack* supplied with your ve­
hicle to raise other vehicles, as these may
slip off the jack - risk of injury!
- A soft or unstab le surface under the jack
may cause the vehicle to slip off the jack .
Always provide a firm base for the jack on
the gro und .
If necessary, use a sturdy
board unde r th e jack .
- On hard, slippe ry surface (such as t iles)
use a rubber mat or s imilar to prevent the
jac k from slipping.

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you .
It is becoming increasingly more and more diffi­
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­
moved before you are able to get to the bulb .
T his applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment .
Sheet metal and bu lb holders can have sharp
edges that can cause serious cuts, pa rts must be
correctly taken apart and then properly put back
together to help prevent breakage o f parts and
long term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your authorized Aud i dea ler rep lace any bulbs fo r
you, since your dealer has the proper tools, the
correct bulbs and the expertise.
Gas di schar ge la mps (Xe no n ligh ts):
Due to the high electr ical voltage, have the bulbs
rep laced by a qualified technician. Headlights
with Xenon light are identified by the hig h volt­
age st icker.
LED headlights* require no maintenance . Please
contact your authorized Audi dea ler if a bulb
needs to be replaced.
_&. WARNING
Changing Xenon lamps wi thout the necessary
equipment can cause serious personal injury .
- Bulbs are pressu rized and can explode when
be ing changed. Potent ial ris k of injury!
- On veh icles equipped with gas disc harge
bu lbs (Xenon light) life-threatening injuries
can resu lt from improper handling of the
high-vo ltage portions of such lamps!
- Only your authorized A udi dealer or quali­
f ied workshop sho uld change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the
