If you wish to improve comfort
when operating the vehicle at
normal load (up to 3 occu­
pants), you can adjust tire
pressures to those specified
for normal vehicle load. Before
operating the vehicle at maxi­ mum load, you must increase
the tire pressures to those
specified for maximum vehicle
load
c> .&. .
Bear in mind that the tire pres­
sure monitoring system can on­
ly monitor the tire pressures
you have stored. The system does not recognize the load
condition of your vehicle.
The effectiveness of the tire pressure monitoring system
will be impaired if you store normal load pressures but then
operate the vehicle at its maxi­
mum load

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.

& 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 labe l on the veh icle
<:?page 235. Driving with a t ire with low
pressure causes the tire to overheat and
can res ult in failure of the tire . Low pres ­
sure can a lso have a negat ive 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 cond itions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor ind i­
cator may be de layed .
- Ask your author ized dealer if r un-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 ident ificat ion "AO" or
"RO" ¢ page 248 have been matched
with your A udi tire pressure monitoring
system. We recommend that you use
these tires.
- The tire pressure monitoring system can
on ly mon itor the t ire pressure of the
driving tires . Check the tire pressu re of
the spa re wheel in the luggage com part­
ment so tha t if ne cessary i t is ready for

Note that the following table was accurate
at the time of print 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 iff icu lt to replace vehicle light bulbs s ince in
many cases, other parts of the car must first
be removed before you are able to get to the
bu lb . Thi s appl ies 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 cuts, 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 housings that have not been
properly resealed.
For 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 bulbs and the expertise.
Gas discharge lamps (Xenon lights):
Due to the high electrical vo ltage, have the
bu lbs rep laced by a qualified technician.
Headlights with Xenon light can be identified
by the high voltage sticker.
LE D headlights* require no ma intenance .
Please contact your authorized Aud i dealer if a
bu lb needs to be replaced.
A WARNING
Contact with high-voltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head­
light bulbs can cause serious personal in­
jury and death . -
Xenon bulbs are pressurized and can ex­
plode when being changed.
- Changing Xenon lamps requires the spe­
cial training, instructions and equip­
ment.
- Only an authorized Audi 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 other qualified work­
shop. Serious personal injury may result
from improperly performed work.
(D Tips
- If you st ill prefer to replace the light
bulbs yourself, be aware that the engine
compartment is a hazardous area to
work in
~ page 214~ &
-It is best to ask your authorized Audi
dealer whenever you need to change a
bulb.

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
(D 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 safe­
ly. Refer to the manufacturer's specifications.
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
Emergency situations 273
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
JU ry.
- 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 214.
(D 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. ..,. •
