tire and the pressure you need and add the a ir
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the tires on your vehicle as listed on the on
your veh icle and in this manual and the kind
of dr iving you plan to do .
Never ex ceed the ma ximum infl ation pres­
su re list ed on the t ire s ide wall for an y rea­
son.
Remember that the vehicle manufacturer, not
the t ire manufacturer, determ ines the correct
tire pressure for the t ires on your vehicle.
It is important to check the tire pressure when
the tires are cold.
- Read the req uired ti re press ure from the tire
pressure label. The tire pressu re labe l is lo­
cated on the drive r's side 8 -p ill ar . The tire
pressure label lists the recommended cold
t ire inflation pressures for the vehicle at its
maximum capacity weight and the tires that
were on your vehicle at the time it was man­
ufactured . For recommended t ire pressures
for normal load condit ions, please see chap­
ter ¢
page 234.
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve .
- Place the air pressure gauge on the valve.
- The tire pressures should only be checked
and adjusted when the tires are cold. The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Re install the valve stem cap on the valve.
When should I ch eck th e tir e pre ssure?
The correct tire pressure is especially impor­
tant at high speeds . The pressure should
therefore be checked at least once a month
and always before start ing a journey. Do not
forget to check the tire pressure for the spare
wheel.
Wh en should I adjust th e tire p re ss ures ?
Ad just the tire pressure to the load you are
carry ing . After changing a wheel
or replacing
Tires an d wheel s 237
whee ls you have to adjust the ti re pressu res
on all whee ls. In addition, yo u m ust then initi­
a lize the new tire pressures in the t ire pres­
sure monitoring system*¢
page 248.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire fa ilure, loss of
control, collision, serious personal injury
or even death.
- When the
ti] warning symbol appears in
the instrument cluster, stop and inspect
the t ires.
- Inco rrect tire pressure and/or underinfla­
tion can cause increased tire wear and can affect the handling of the vehicle and
stopping ability.
- Inco rrect tire pressures and/or unde rin­
flation can a lso lead to sudden t ire fail­
ure, including a blowou t and sudden de­
f lation, caus ing loss of veh icle contro l.
- The drive r is responsib le for the correct
tire pressures for all tires on the veh icle.
The applicable pressure values are locat ­
ed on a sticke r on the driver's side 8-pil­
lar.
- On ly when all tires on the vehicle are fil ­
led to the correct pressure, the tire pres­
sure mon itor ing system* can work cor­
rectly.
- The use of incorrect tire pressu re va lues
can lead to acc idents or other damage.
Therefore it is essential that the driver
observe the spec ified t ire pressure values
for the t ires and the correct pressures for
the function of the t i re p ress ure monito r­
ing system*.
- Always inf late t ires to the recommended
and correct t ire p ressure before dr iv ing
off.
- Driving with unde rinflated tires bend
mo re, lett ing t hem get too hot resulting
in tre ad separation, sudden tire failure
and loss of cont rol.
- Excessive speed and/overloading can
cause heat b uild- up, sudden tire failure
and loss of cont rol.

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 whee ls on the veh i­
cle that prevent the TPMS from funct io ni ng
p roperly . Always check the T PMS malfunct ion
tellta le afte r 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 pressure monitoring system
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. 179 Display : underinflatio n warning
Using the ABS sensors, the tire pressure moni­
toring system compares the t ire tread circum­
ference and vibration characteristics of the in­
d iv idual tires . If the pressure decreases in one
or mo re tires, th is is indicated in the instru­
ment clus ter with a
IE warning symbol and a
message ¢
fig. 179. The driver message in the
display goes out after 5 seconds. The driver message can be displayed again by pressing
the
! SET ! button. If only one tire is affected,
the display will indicate its pos ition.
The tire pressure monitoring system must be reset via radio or MMI* each time the pres­
sures are adjusted (e.g . when switching be ­
tween partia l and full load pressure) or after
changing or replacing a t ire on your vehicle
¢
page 250. The TPMS indicator only moni­
tors the tire pressure that you have prev iously

Bulbs
Replacing 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
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 . T his appl ies especially to the light bu lbs
in the front of your car which you can on ly
reach through the engine compartment .
Sheet metal and bulb ho lders can have sharp
edges that can cause ser ious cuts, parts must
be correctly taken apart and then p roperly put
back together to help prevent breakage of
parts and long term damage from water that
can enter housings that have not been proper­
l y resealed.
F or your safety, we recommend that you have
your authorized Audi dealer replace any bulbs
for you, since your dealer has the proper tools,
the correct bu lbs and the expertise.
G as disch arge la mp s (Xe no n li ght s)*:
Due to the high electrical vo ltage, have the
bu lbs rep laced by a qualified technician.
H eadlights with Xenon l ight a re identified by
the high voltage sticker.
& WARNING
Changing Xenon lamps without the neces ­
sary equipment can cause serious personal
injury.
- Bul bs are pressurized and can exp lode
when being changed . Potential risk of in­
jury!
- On vehicles equipped with gas discharge
bulbs (Xenon light) * life-threatening in­
jur ies can result from improper handling
of the high-voltage portions of such
lamps!
- Only your authorized Aud i dea ler or a
qualified workshop should change the
bulbs in gas discharge lamps. There a re
Fu ses and bulb s 261
parts with sharp edges on the open ings
and on the bulb holders that can cause
serious cuts. If you are uncertain about
what to do, have the work performed by
an author ized Audi dealer or other quali­
fied workshop . Ser ious personal injury
may result from improperly perfo rmed
wo rk.
(j) Tips
- If you still prefer to replace the light
bulbs yourself , be aware that the engine
compartment is a hazardous area to
work in

262 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 operations.
Starting by pushing or
towing
Q;) Note
Vehicles with an automatic transmission
cannot be started by pushing or towing.
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 vehicle,
using a
pair of jumper cables to start the en­
gine .
Jumper cables
Use only jumper cables of sufficiently
large cross section to carry the starter current
safely. Refer to the manufacturer's specifica­
ti ons.
Use only jumper cables with
insulated termi­
nal clamps which are distinctly marked :
plus(+) cable in most cases colored red
minus (-) cable
in most cases colored black .
A WARNING
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 lean­
ing over the battery whenever possible. -
A discharged battery can freeze at tem­
peratures just below 32 °F (0 °C). Before
connecting a jumper cable, you must
thaw the frozen battery completely, 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 voltage 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 different voltage
or substantially different "Ah" rating
may cause an explosion and personal in­
jury.
- Never charge a frozen battery. 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 batteries of different voltage or
substantially different capacity (Ah) rat­
ing may cause an explosion 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 all
WARNINGS¢
page 208, Engine com­
partment.
@ Note
- Applying a higher voltage booster bat­
tery will cause expensive damage to sen­
sitive electronic components, such as
control units, relays, radio, 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. ..,.
