Winter operation
The cold time of year places a special strain on
the battery, resulting in reduced starting pow
er. So before the cold weather starts, have the battery inspected and charged as necessary.
A WARNING
-All work on the battery requires technical knowledge. Please contact an authorized
Audi dealer or another authorized facility
for questions about the battery -danger
of acid burns and explosion hazard!
- The battery must not be opened! Do not try to change the battery's liquid level,
otherwise detonating gas will escape
from the battery- explosion hazard!

A WARNING
Whenever working on the battery or on
the electrical system, there is the risk of injury, accident and even fire. Read and
heed the following WARNINGS:
- Always wear eye protection . Do not let
battery acid or any lead particles get on
your skin or clothing. Shield your eyes.
Checking and filling 179
Explosive gases can cause blindness or
other injury.
- Battery acid contains sulfuric acid. Sulfu
ric acid can cause blindness and severe
burns.
- Always wear gloves and eye protection.
Do not tilt the battery because acid
could leak out of the ventilation open
ings.
- If you get battery acid in your eyes or
on your skin, immediately rinse with
cold water for several minutes and get medical attention.
- If you should ingest any battery acid,
seek medical attention immediately.
- Do not expose the battery to an open
flame, electric sparks or an open light.
- Do not smoke.
- Do not interchange the positive and neg-
ative cables.
- When working on the battery, be sure
not to short-circuit the terminals with
tools or other metal objects. This would
cause the battery to heat up very quickly,
which could lead to damage or explosion
and personal injury.
- When a battery is charged, it produces
hydrogen gas which is explosive and
could cause personal injury.
- Always keep the battery well out of the
reach of children.
- Before work is done on the electrical sys
tem, disconnect the negative ground ca
ble.
- Before performing any work on the elec trical system, switch off the engine and ignition as well as any electrical equip
ment. The negative cable on the battery
must be disconnected. If you are just go
ing to replace a light bulb, then it is
enough to switch off the lights.
- Before disconnecting the battery, switch
off the anti-theft alarm system! Other
wise you will set off the alarm.
- When disconnecting the battery, first
disconnect the negative cable and then
the positive cable.

¢page 37.
When charging at low voltages (e.g . with a
trickle charger ), the battery cables do not
have to be disconnected first. Before charging
at
high voltages, i.e. "fast charging", you
must disconnect both cables. In either case,
follow the instructions from the manufacturer
of the charger .
Fastcharging a battery is
dangerous ¢ & in
Working on the battery on page 179 .
It re
quires special charging equipment and the knowledge to go with it. We recommend hav
ing your battery fast charged only by a quali
fied workshop.
A discharged battery can
freeze at tempera
tures of only 32 °F (0 °C) . Allow a frozen bat
tery to thaw completely before attempting to
charge it¢ & . However, we recommend not
using a thawed battery again because the bat
tery casing can be cracked due to ice forma
tion and can leak battery acid .
Do not open the battery caps when charging
the battery.
_& WARNING
-
Charging a battery can be dangerous.
- Never charge a frozen battery .
It may ex
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out first.
- Do not reuse batteries which were fro
zen. The battery housing may have
cracked and weakened when the battery
froze.
- Charge the battery in a well ventilated
area. Keep away from open flame or elec
trical spark. Do not smoke. Hydrogen gas
generated by the battery is explosive.
- To reduce the danger of explosion , never
connect or disconnect charger cables
while the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted by a compe
tent technician with the proper equip ment.
Checking and filling 181
- Battery acid that may spill during charg
ing should be washed off with a solution
of warm water and baking soda to neu
tralize the acid .
@ Note
Never use a fast charger as a booster to
start the engine. This will seriously dam
age sensitive electronic components, such
as control units, relays, radio, etc ., as well
as the battery charger .
(D Tips
-The vehicle battery must not be charged
with a standard small charger that plugs
into the cigarette lighter or outlet .
- Only charge the battery through the con
nections in the luggage compartment.
Replacing the battery
The new battery mus t have the same specifi
cations as the old one.
Your vehicle is equipped with an intelligent
energy management system for distributing
electricity¢
page 147 . The battery charges
better in vehicles with the energy manage
ment system than in vehicles without the sys
tem . To ensure that the additional power is
available after replacing the battery , replacing
with the same type of battery from the same manufacturer (like the battery that was deliv
ered with the vehicle) is recommended. An au
thorized dealer must code the battery in the
energy management control module.
The new battery must have the same capacity,
voltage (12 volts), current and design and it
must be sealed with plugs. The battery must
conform to the standards TL 825 06 (from
April 2008) and VW 7 SO 73 (from April 2010).
Since the vehicle battery is difficu lt to reach,
we recommend having the battery replaced by
an authori zed Audi RB dealer or other quali-
fied workshop . ..,. •

soon as possible, and inflate them to the
proper pressure . Driving on a significant ly un
der-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation a l
so reduces fuel efficiency and tire tread l ife,
and may affect the veh icle 's handling and
stopping ab ility.
Please note that the TPMS is not a substitute
for proper t ire maintenance, and it is the dr iv
er's responsib ility to ma inta in correct t ire
p ress ure , even if under- inflation has not
reached the leve l to t rigger illumination of the
TPMS low tire pressure telltale .
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indicate when
the system is not ope rating properly. The
TPMS malfunc tion indica to r i s combined wi th
the low t ire pr essu re tellta le. When the sys
tem detec ts a ma lf u nct ion, the te lltale will
flash for approximately one minute and then remain continuo usly ill uminated . This se
q uence will continue upon subsequent vehicle
start-ups as long as the malfunction ex ists.
When the malfunction indicator is ill uminat
ed, the system may not be able to detect or
signa l low t ire pressure as intended . TPMS
malfunct ions may occ ur for a variety of rea
sons, including the ins talla tio n of replace
ment or a lternate tires o r whee ls on the veh i
cle that prevent the TPMS from funct io ni ng
p roperly . Always check the TPMS malfunct ion
t ellta le afte r replacing one o r more t ires or
wheels o n your veh icle to ensure tha t the re
p lacemen t or a lternate tires and wheels allow
the TPMS to continue to function properly .
Introduction
The tire pressure monitoring system monitors
air pressure in all four road wheels while the
vehicle is moving .
As soon as the tire pressu re mo nitor ing sys
tem senses a s ignificant loss of a ir pressure in
one or severa l ti res, text messages and yellow
symbo ls appear in the instr ument cluster dis
p lay to alert the driver. The
[ti warning light
Tire s an d wheel s 201
in the instrument cluster comes on when the
ti re is significant ly underinflated .
T he wa rni ng lig ht
[ti also illu minates i n the
case of a system mal funct io n.
Be aware that t ire pressure is a lso dependent
o n the tempe ratu re of the t ire. For eve ry 18 ° F
(10 °C) incre ase in tir e te mper ature, tire pres
s u re inc reases by about 1.5 psi (0 .1 bar). The
ti re warms up while the ve hicle is moving and
tire p ress ure rises . So you sho uld ad just tire
pressure only when they a re
cold, when the
temperature of the tires is ro ughly the same
as the ambient a ir temperature.
In order to keep the tire press ure monito ring
system p roperly ca librated, t ire press ure on
all four tires sho uld be checked at regu lar in
terva ls.
The tire pressure is shown on the label located
on the dr iver's side B-pillar (v is ib le when the
door is open) .
A WARNING
When the tire pressure mo nitoring system
war ning light is lit , one o r m ore of your
tires is s ignificantly under-infla ted . You
shou ld stop and check your tires as soon as
pos sib le, and in flate t hem to the proper
p ress ure a s in dic ate d on the ve hicle's ti re
p ress ure lab el
¢page 187. Driving on a
significantly under -inflated ti re causes t he
tire to over heat and can lead to tire failure .
Under-inflat ion also is like ly to impair the
vehicle's handling and stopping ab ility.
@ For the sake of the environment
D riving wit h un der -inflated tires red uces
fuel efficiency an d tire t read life.
(D Tips
- E ach tire should be chec ked monthly
w hen the tem perature of the tires is
about the same as amb ient a ir tempera
t u re and set to the recommended infla
tion press ure as specified on the tire
pressure label¢
page 187.

.. Remove the "max. 50 mph" (80 km/h)
sticker from the sealant bottle and affix it to
the instrument cluster in the dr iver's view.
A WARNING
- Turn the hazard flashers on if you have a
flat tire in moving traffic. In this way you
protect yourself and other road users .
- Make sure that all passengers are in a
safe place, out of the dange r zone (fo r
example, behind a guard ra il).
