reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indica te when
the system is not operating properly . The
TPMS malfunction indicator is combined with
the low tire pressure tellta le . When the sys­
tem detects a malfunct ion, the telltale will
flash for approximately one minute and then
remain cont inuous ly illuminated. This se ­
quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction ex ists .
When the malfunct ion indicator is illuminat­
ed, the system may not be able to detect or
sig nal low t ire pressure as intended . TPMS
malfunct ions may occur for a variety of rea­
sons, including the installa tio n of replace­
ment or a lternate tires or whee ls on the veh i­
cle that prevent the TPMS from funct ion ing
properly. Always check the TPMS malfunction
tellta le after replacing one or more tires or
wheels on your veh icle to ensure that the re­
placement or alternate tires and wheels allow
the
TPMS to continue to function properly.

266 Tire s and wheels
& WARNING
-If the tire pressure warning light ti] in
the instrument cluster turns on, the
pressure in one or more tires is too low.
Reduce the vehicle speed immediately
and avoid any hard steering or braking
maneuvers . Stop as soon as possible,
check the t ire and inflate the tire to the
correct pressure, which is specified on
the tire pressu re label on the veh icle
¢ page 240. Driving with a t ire with low
pressure causes the tire to overheat and
can result in failure of the tire . Low pres ­
sure can a lso have a negative effect on
the driving and braking behavior of the
vehicle.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the t ire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor ind i­
cator may be delayed .
- Ask your author ized dealer if run-flat
t ires may be used on your vehicle.
- The tire pressure monitoring system can
also stop work ing when there is an ESC
malfunction.
- Using snow chains may result in a system
malfunction.
- The tires with the identification "AO" or
"RO" ¢ page 254 have been matched
with your Audi tire pressure monitoring
system. We recommend that you use
these tires.
- The tire pressure monitoring system can
only mon itor the t ire pressure of the
driving tires . Check the tire pressure of
the spare wheel in the luggage compart­ ment so that if necessary it is ready for
us e.

Storing tire pressures
Applies to vehicles: wit h tire press ure mo nitor ing system
A change in tire pressure or a change in tires
must be stored in the system.
The tire pressure is stored in the MMI.
.. Make sure before storing that the tire pres ­
sures of a ll four tires meet the specified va l­
ues and are adapted to the load. Otherwise
the system could malfunction

@ Tips
Note that the following table was accurate
at the time of pr int ing and is subject to
change.
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 increas ingly more and more
d ifficult to replace veh icle light bulbs since in
many cases, other parts of the car must first
be removed before you a re able to get to the
bu lb. This app lies especia lly 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 sha rp
edges that can cause ser ious c uts, and parts
must be co rrectly taken apart and then prop ­
erly put back together to help prevent break­
age of parts and long term damage from wa­
ter that can enter hous ings that have not been
properly resealed.
F or your safety, we recommend that you have
your authorized Audi dealer rep lace any bulbs
for you, since your dealer has the proper tools,
the correct bulbs and the expertise.
G as discha rge l amps (Xenon light s):
Due to the high elect rical voltage, have the
bu lbs rep laced by a qualified technician.
Headlights wi th Xenon light can be identified
by the high voltage sticker .
L ED headlights* requ ire no ma intenance .
Pl ease contact yo ur a uthorized Aud i dealer if a
bu lb needs to be replaced.
A WARNING
Contact with high-voltage components of
the electrica l system and improper re­
placement of gas discharge (Xenon) head­
light bulbs can cause serious personal in­
jury and death .
Fuses and bulb s 2 79
- Xenon bu lbs are pressur ized and can ex­
plode when being changed.
- Changing Xenon lamps requires the spe­
cial tra ining, instructions and equip­
ment.
- On ly an authorized A udi dealer or other
qualified workshop should change the bulbs in gas discharge lamps.
A WARNING
There are parts with sharp edges on the
openings and on the bulb holders that can
cause ser ious cuts .
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dealer or othe r qualified work­
shop. Ser ious personal inju ry may result
from imprope rly performed wo rk.
(D Tips
- If you still prefer to replace the light
bulbs you rself, be aware that the engine
compartment is a hazardous area to
work in
c:::> page 21 lc:::> &
- It is best to ask your authorized Audi
dealer whenever you need to change a
bulb.

280 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 vehicle,
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 217.
(D Note
-App lying a higher voltage booster bat­
tery will cause expensive damage to sen­
sitive electronic components, such as
contro l units, relays, radio, etc .
- Th ere must be no electrical contact be­
tween the vehicles as otherwise current cou ld already start to f low as soon as the
positive(+) terminals are connected. .,.
