tive electronic components, such as control
units, relays, radio, etc., as well as the battery
charger.
Battery replacement
T he new battery must have the same specifica­
t ions and dimensions as the original equipmen t
bat tery.
Int elli g ent en ergy managem ent in your vehicle is
responsible for distributing the electrical energy
throughout your vehicle
r=> page 195. The intelli­
gent energy management system will keep the
engine battery charged better than veh icles w ith­
out this system . To make sure the addit ional
e lectrical energy is avai lab le once again after you
have changed the battery, we recommend that
you install batteries of the same type and manu­ facture on ly (the same as those installed at the
time your vehicle was delivered). Specifications
are listed on the battery housing. Your author­
i z ed dealer must code the battery in the energy
management system to enable you to use the en­
ergy management functions correctly after re ­
placing the battery .
The new battery must have the same capacity,
voltage (12 volts) , amperage, construction and
plug sealing .
When installing the battery, make sure the igni­
tion and all electrical consumers are sw itched
off.
CD Note
- Make sure the ventilation hose on the s ide
of the battery is connected, otherw ise
fumes or battery ac id can leak out.
- Vehicles with the Start-Stop-System* are equipped with a special cycle-proof AGM battery . Installing a d ifferent type of bat­
tery can cause problems in the vehicle elec -
234
trical system. When replacing the vehicle
battery, always install one with the same
specifications as the original battery .
- Battery mounts and clamps m ust always be
secured correctly.
- Read and follow the warnings under
¢ page 231, Working on the battery before
performing any work on the battery .
@ For the sake of the environment
Because of the p roblem of proper disposal of
a battery, we recommend your authorized

_& WARNING
Temperature grades apply to tires that are
properly inflated and not over or underinf lat ­
ed.
Tire pressure monitoring system
U) General notes
Applies to: vehicles with tire pressure monito ring system
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflat ion pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire infla­
tion pressure fo r those tir es) .
As an added safety feature, your vehicle has been
equipped with a t ire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant­
ly under-inflated . Accord ingly, when the low tire
p ressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop­
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsib ility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunct ion indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is comb ined w ith the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one minute and then remain cont inuous ly
illuminated. This sequence will continue upon
254
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunction indicator is illum inated,
the system may not be able to detect or s ignal
low tire pressure as intended . TPMS malfunctions
may occur for a variety of reasons, including the
i nstallation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
whee ls allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
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 . 209 Instrument cl uste r: indicator light with me ssage
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread c ircumfer­
ence and v ibration characteristics of the individu­
al tires.
If the pressure changes in one or more
ti res, this is ind icated in the instrument cluster
display with an indicator light
[I] and a message.
If only one tire is affected, the locat ion of that
tire will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle ¢
page 255. The tire pressure moni­
tor ing system only monitors the tire pressure you
have stored . Refer to the t ire pressure label for ..,.

Fuses a nd bul bs
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 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 bu lb .
This applies espec ially to the light bulbs in the
front of your car wh ich 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
m ust be correctly taken apa rt 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 properly re­
sealed.
For 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 bulbs and the expertise.
G as di sc harg e l am ps (Xe non li ghts):
Due to the high electrical voltage, have the bulbs
replaced by a qua lified technic ian . Headlights
with Xenon light can be identified by the high
voltage sticker.
LED headlights* require no maintenance. Please
contact your authorized Aud i dealer if a bulb
needs to be replaced.
A WARNING
Contact w ith high-voltage components of the
electrical system and improper rep lacement
of gas discharge (Xenon) headlight bulbs can
cause serious personal injury and death.
- Xenon bulbs are pressurized and can ex­
plode when being changed.
- Changing Xenon lamps requires the special training, instructions and equipment.
- Only an a uthorized Audi dea ler or other
qualified workshop should change the bulbs
in gas discharge lamps .
270
A WARNING
-
There are 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 authorized Audi
dealer or other qualified workshop. Ser ious
pe rsonal injury may resu lt from improperly
pe rformed wor k.
@ Tips
- If you must replace the light bulbs yourself,
always remember that the eng ine compart­
ment of any vehicle is a hazardous area to
work in. Always read and heed all WARN­ INGS ~
page 220.
-It is best to ask your authorized Audi dealer
whenever you need to change a bulb.

Starting with jumper
cables
If necessary, the engine can be started by con­
necting it to the battery of another vehicle .
If the engine shou ld fail to start because of a dis ­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumpe r cables to start the engine.
Jumper cables
Use only jumper cables of suffic iently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated term inal
clamps which are dis tinct ly marked :
plus(+) cable in most cases colored re d
minus( -) cable
in most cases colored blac k.

frozen battery completely, otherwise 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 exp losion.
- Vehicle batteries generate exp losive gases.
Keep sparks, flame and lighted cigarettes
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 battery. Use of
batter ies of different voltage or substantial­
ly different "Ah" rating may cause an exp lo­
sion 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 weak­
ened .
- Use of batter ies of different voltage or sub ­
stantially different capacity (Ah) rating may
cause an exp losion and injury. The capac ity
(Ah) of the booster battery should not be
lowe r than that of the discharged battery.
- Before you check anything in the eng ine
compartment, always read and heed all
WARNINGS

(D Note
-Applying a higher voltage booster battery
will cause expensive damage to sensitive
electronic components, such as control
units, relays, radio, etc.
- Th ere must be no electrical contact between
the vehicles as otherwise current could al­
ready start to flow as soon as the positive
