250 Tires and wheels
When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low tire pressure as intended . TPMS
malfunctions may occur for a variety of rea­
sons, including the installation of replace­ ment or alternate tires or wheels on the vehi ­
cle that prevent the TPMS from funct ioning
properly . Always check the TPMS malfunction
telltale after replacing one or more t ires or
wheels on your veh icle 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
Applies to vehicles: with tire p ressure mo nitoring syste m
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. 181 Display : underinflatio n warning
Fig. 182 Display : Syste m mal functio n
Using the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum­
ference and vibration characteristics of the in­
d ividual tires.
If the pressure decreases in one
or more tires, th is is indicated in the instru­
ment cluster with a warning symbol
'9] and a
message ¢
fig . 181.
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad- justed
(e.g. when switching between partial
and full load pressure) or after changing or re­
placing a tire on your vehicle ¢
page 251. You
can find the recommended tire pressures for
your vehicle on the label on driver 's side B-pil­
lar ¢
page 235 .
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the tire pressure in one or more tires is too
low,
- the tire has structural damage,
- the tire pressure was changed, wheels rotat -
ed or replaced but the TPMS was not reset

A WARNING
--If the tire pressure indicator appears in
the instrument cluster display, one or more of your tires is significant ly under­
inflated. Reduce you r speed immediately
and avoid any hard steer ing 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 235. Driving on a
significantly under- inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to

proximate ly) opposite one, to keep the
whee l centered.
@ Note
When removing or installing the wheel,
the rim could hit the brake rotor and dam­
age the rotor. Work carefully and have a
second person help you.
@ Tips
Never use the hexagonal socket in the han­
dle of the screwdriver to loosen or tighten
the wheel bolts .
- Pull the reversible b lade from the screw­
driver before you use the hexagonal
socket in the handle to turn the whee l
bo lts.
- When mounting tires with
unid irectional
t re ad design
make sure the tread pat­
tern is pointed the right way
~ page 258.
- The wheel bolts should be clean and easy
to turn . Check for d irt and corrosion on
the mat ing surfaces of both the whee l
and the hub. Remove all dirt from these
s ur faces before remo unt ing the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction .
Using a sp are t ire w ith a tre ad pattern
intended for use in a specific direction
When using a spare t ire with a tread patter n
intended for use in a spec ific d irection , please
note the following :
- The direct ion of rotation is marked by an ar­
row on the side of the ti re .
- If the spare tire has to be installed in the in­
correct direct ion, use the spare tire only
temporarily s ince the tire will not be able to
achieve its optim um performance cha racter­
is tic s wit h regard to aquap la ni ng, no ise and
wear .
- We recommend that you pay part icu la r at­
t en tion to th is fact d uring wet wea ther and
t ha t you adjust you r speed to match road
conditions .
- Replace the fl at tir e with a new o ne an d
have it insta lled on you r vehicle as soon as
possible to restore the handling advantages
of a u nidirectional tire .
Notes on wheel changing
Please read the information ¢ page 242, New
tires and replacing tires and wheels
if you a re
going to use a spare tire which is different
from the ti res on your vehicle .
After you change a tire:
- Check the tire pre ssure on the spare imme­
diately after install ation.
- Have th e whe el bolt tight ening torqu e
c hecked with a torque wrench as soon a s
possible by your author ized Audi dealer or
a qualified service stat ion.
- With steel and alloy wheel rims, the wheel
bolt s are cor re ctl y tightened at a torque of
90 ft lb (120 Nm ).
- If you noti ce that the wheel bolts are cor­
roded and diffi cult to turn while changing
a ti re , they should be replaced before you

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized 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
bu lb. Th is applies especia lly to the light bu lbs
i n 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 ser ious cuts, and parts
must be correctly taken apart and then prop­
e rly p ut back together to help prevent break­
age of parts and long term damage from wa­
ter that can enter housings that have not been properly resealed.
F or your safety, we recommend that you have
your authorized Audi dealer replace any bu lbs
for you, since your dealer has the proper tools, the correct b ulbs and the expertise.
Gas disc harge la mp s (X enon li ght s):
Due to the high electrical voltage, have the
bu lbs rep laced by a qualified technician.
H eadlights with Xenon l ight can be identified
by the high voltage stic ke r.
LED headlights* requ ire no ma intenance .
Please contact your autho rized Aud i deale r if a
bu lb needs to be replaced.
Fu ses and bulb s
A WARNING
Contact with h igh-vo ltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head­
light bulbs can cause ser ious personal in­
jury and death.
- Xenon bulbs are pressur ized and can ex­
plode when being changed.
- Changing Xenon lamps requ ires the spe­
cial tra ining, instructions and equip­
ment.
- On ly an authorized Audi dealer or other
qualified wor kshop should change the
bu lbs in gas discharge lamps .
A WARNING
There are parts with sharp edges on the
openings and on the bulb holders tha t can
cause serious c uts.
- If you are uncertain abo ut what to do,
have the work performed by an author­
ized Audi dealer or other qualified work­
shop . Ser ious personal inj ury may result
from improperly performed work.
(D Tips
- If you must replace the light bulbs your­
sel f, a lways remember that the engine
compartment of any vehicle is a hazard­
ous area to work in. A lways read and
heed all WARNINGS
¢ page 210, Engine
compartment¢ ,&..
- It is best to ask your authorized Audi
dealer whenever yo u need to change a
bulb.

264 Emergency situations
Emergency situations
General
This chapter is intended for trained emer­
gency crews and working personnel who
have the necessary tools and equipment to
perform these ope rations.
Starting by pushing or
towing
Q;) Note
Vehicles w ith an automatic transmission
cannot be started by pus hing o r tow ing.
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi­
cle.
If the engine should fail to start because of a
discharged or weak battery, the battery can be
connected to the battery of
another veh icle,
using a
pair of jumpe r cables to start the en­
g ine .
Jumper cables
Use only jumper cables of sufficiently large
cross section to carry the starter current safe­
ly. Refer to the manufacturer's specif ications.
Use only jumper cables with
insulated termi­
na l clamps which are distinctly marked:
plus(+) cable in most cases colored red
minu s(-) cable
in most cases colored black .
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal
inju ry. Follow the instructions below for
safe handling of your veh icle's battery.
- Always shield you r eyes and avoid lean­
ing over the battery whenever possible.
- A discharged battery can freeze at tem­
peratures just be low 32 °F (0 °C). Before connecting a
jumper cable, you must
thaw the frozen battery complete ly, oth­
erwise it could explode.
- Do not allow battery acid 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 explosive gas­
es. Keep sparks, flame and lighted ciga­
rettes away from batteries.
- Do not try to jump start any vehicle with a low acid level in the battery.
- The vo ltage of the booster battery must
also have a 12-Volt rating. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged bat­
tery . Use of batteries of d ifferent voltage
or substantially different "Ah" rating
may cause an exp losion and personal in­
jury.
- Never charge a frozen batte ry. Gas trap­
ped 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 batter ies of different voltage or
substantially different capacity (Ah) rat­
ing may cause an exp losion and injury.
The capacity (Ah) of the booster battery
should not be lower than that of the dis ­
charged battery.
- Before you check anything in the engine
compartment, always read and heed a ll
WARNINGS
¢page 210, Engine com­
partment.
«I) Note
-Applying a higher voltage booster bat­
tery will cause expensive damage to sen­
sitive electronic components, such as
contro l units, relays, rad io, etc.
- There must be no electrical contact be­
tween the vehicles as otherwise current
could already start to flow as soon as the
positive(+) terminals are connected. ..,_
