Airbag syste m
the system inspected immediately by your
authorized Aud i dealer. It is possible that
the a irbag will inflate when it is not sup­
posed to, or will not inflate when it should.
A WARNING
If the front airbag inflates, a child without a
child restra int, or in a rearward-facing child
safety seat, or in a forward-facing child re­
st raint that has not been p roperly installed
w ill be seriously injured and can be killed.
- If you must install a rearward-fac ing child
seat on the front passenger seat because of
exceptional c ircumstances and the
PA SSEN­
GER AIR BAG
OFF ,;; light does not appear
and stay on, have the airbag system inspect­
ed by your Audi dealer.
- If, in exceptiona l circumstances, you must
install a forward-facing chi ld restraint on
the front passenger seat, always move the
seat into its rearmost pos ition in the seat's
fore and aft adjustment range, as far away
from the airbag as possible. The backrest
must be adjusted to an upright posit ion .
Make sure that the PASSENGER AIR BAG
OFF ,;; light comes on and stays on a ll the
t ime whenever the ignition is switched on.
A WARNING
If the PASSENGER AIR BAG OFF ~; ligh t does
not go o ut when an adult is s itting on the
front passenger seat after taking the steps described above, have the airbag system in­
spected by your Audi dealer before transport­
ing anyone on the front passenger seat.
(D Tips
If the capacitive passenger detection system
determines that the front passenger seat is
empty, the frontal airbag on the passenger
side w ill be turned off, and the

ing, servicing or repair ing a part in an area of the
vehicle can damage a part of an airbag system
and prevent that system from work ing properly
i n a coll is ion.
There are some important things you have to know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment .
A WARNING
Improper care, servicing and repair proce­
du res can increase the risk of personal in jury
and death by p reventing an airbag from de­
p loying when needed or deploy ing an a irbag
unexpectedly:
-
- Never cover, obstruct, or change the steer­
ing wheel ho rn pad or airbag cover or the in­
s trumen t panel or modify them in any way.
- Never attach any objects s uch as c up ho lde rs
or telephone mountings to the surfaces cov­
ering the a irbag un its.
- For cleaning the horn p ad or instr ument
panel, use only a soft, dry doth or one mois­
tened w ith plain water . Solvents or cleaners
could damage the airbag cover or change
the stiffness o r strength of the material so
that the airbag cannot deploy and protect properly.
- Never repair, ad just, or change any parts o f
the airbag system.
- All work on the steering wheel, instrument
panel, front seats or e lectr ica l system ( in­
cluding the installation of a udio eq uipment,
cellular te lephones and CB radios, etc.)
m ust be performed by a qualified techn ician
who has the training and spec ial equipment
necessary.
- For any work on the airbag system, we
strong ly recommend tha t you see you r au­
thori zed A udi dealer or qualified wo rkshop.
- Never modify the front bumper or pa rts of
the vehicle body.

fires and injuries .
- If you must transport fuel in a fue l contain ­
er, please note the following:
Ch eck ing and F illing
- Always place a fue l container on the
ground before filling . Never fill the fue l
container with fuel while it is in or on the
vehicle . Electrostatic charge can occur
wh ile refueling and the fuel vapors could
i gnite .
- For fuel containers made of metal, the fuel p ump nozzle must always maintai n
contact with the conta iner to reduce the
r isk of s tat ic charge.
- Insert the fuel pump nozz le as far as pos­
s ible into the fi lle r opening w hile refuel­
ing .
-Fo llow lega l requ irements when using,
stor ing and t ransporti ng f uel conta iners.
- Make su re that the fuel containe r meets
t h e in dust ry standa rds, for example ANS I
o r ASTM F8S2 -86.
@ Note
- Remove fuel that has overflowed onto any
veh icle components immediately to reduce
the risk of damage to the vehicle.
- Never drive unt il the fuel
tank is completely
empty. The irregula r supply of fue l that re­
sults from that can cause eng ine misfi res.
U nc ombus ted fuel will ente r th e exhaus t
system and increase the risk of damage to

Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility 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 malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation 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
wheels allow the TPMS to continue to function
properly.
Description
Applies to: vehicles with tire pressure monitor ing system
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
T he system uses sensors that measure the tem ­
perature and pressure in the tires . The data is
sent from these sensors to the control module by radio frequency.
T he tire pressure monitoring system shows the
current pressures and temperatures of the tires
in the Infotainment system while driving
¢ page 264. It also compares the current tire
pressures with the stored tire pressures and
gives a warning if the tire pressure is different
from what is stored
¢ page 264 .
Wheels
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures. You must store the tire pressures again
¢ page 264:
- every time the tire pressures change, for exam­
ple when the load in the vehicle changes,
- after replacing a tire, or
- if wheels with new wheel sensors are used.
_& WARNING
- The tire pressure monitoring system assists
the driver in monitoring tire pressures. The
driver is responsible for having the tires in­
flated to the correct pressure.
- Do not change the tire pressure when the
temperature of the tire is extremely high.
This could result in serious damage to the
tire and even cause the tire to burst, in­
creasing the risk of an accident.
- A tire with low pressure flexes more. This heats the tire up too much. This could cause
the tread to separate and even cause the
tire to burst, increasing the risk of an acci­
dent.
- The tire pressure monitoring system does not warn about damage or defects in the
tire construction that could cause the tire to
burst, for example. Inspect your tires regu­
larly.
(D Tips
- If tires are replaced, the sensors/valves do
not need to be removed or replaced . Just re­
placed the valve stem and, if necessary, the
valve and the wheel electronics. If you have questions, see an authorized Audi dealer or
authorized Audi Service Facility.
- An incorrect display or a malfunction in the
tire pressure monitoring system can occur
after using the tire mobility kit. Have the
sensors replaced by an authorized Audi
dealer or authori zed Audi Service Facility.
- For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see

Emergency situations
General
This chapter is intended for trained emergency
crews and working personnel who have the nec­
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
~ Note
Vehicles with an automatic transmission can­
not be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by con­
necting it to the battery of another vehicle .
If the engine should 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 jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
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 in­
jury. Follow the instructions below for safe
handling of your vehicle's battery .
-Always shield your eyes and avoid leaning
over the battery whenever possible.
-A dead battery can freeze at temperatures
around 32 °F (0 °C) . If the vehicle battery is
frozen, you must thaw it before connecting
the jump start cables. If you do not, this in-
Emergency situations
creases the risk of an explosion and chemi­
cal burns. After jump starting the vehicle,
drive to an authorized Audi dealer or author­ ized Audi Service Facility immediately to
have the vehicle battery checked.
- 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 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 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 battery. Use of
batteries of different voltage or substantial­
ly different "Ah " rating may cause an explo­
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 batteries of different voltage or sub­
stantially different capacity (Ah) rating may
cause an explosion and injury. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c>page 233.
@ Note
- Applying a higher voltage booster battery
will cause expensive damage to sensitive
electronic components, such as control
units, relays, radio, etc.
- There must be no electrical contact between
the vehicles as otherwise current could al­
ready start to flow as soon as the positive
( + ) terminals are connected.
