204 Tires and wheels
Handling characteristics change when
dr iving with low air pressure or with flat
tires even with special run-flat tires
A low pressure or flat front tire affects vehicle
handling characteristics by pulling the vehicle
slightly to the side where the tire is mounted
and reduces braking performance.
A low pressure or flat
rear tire also affects
driving characteristics by pul ling to the side
where the tire is mounted and also reduces
brak ing performance. The effect on vehicle
handling is most not iceable when driving
around curves.
& WARNING
Changed vehicle handling characteristics
when driving in the run -flat mode can
cause loss of vehicle contro l, a c rash and
serious personal in jury.
- Driving on special run-flat tires in the
run-flat mode will change vehicle han­
dling characteristics during braking,
when cornering and under heavy acceler­
ation .
- Never drive faster than the maximum
rated speed of 50 mph (80 km/h) when
dr iv ing in the run-flat mode .
- Always adjust vehicle speed to traffic,
road and weather cond itions and drive
slower than the max imum rated speed if
necessary weather and road conditions
are taken into account.
- Always obey speed limits and other traf­
fic laws.
(D Note
We a lways recommend driving w ith even
more care when using these specia l tires in
the run-flat mode. Always avo id sudden
maneuvers.
Replacing run-flat tires and rims
Applies to veh icles: w it h Run -flat tires
Your vehicle was especially designed to use
special run-flat tires .
You may use and combine only approved run­
flat tires and special matching rims that have
been designed for run -flat tires . Mounting
special run-flat tires on standard whee ls will
not work and will not provide the advantages
fo the run-falt feature. Never use special run­
flat tires on standa rd whee l rims.
After dr iving w ith a t ire in the run-flat mode,
always have the veh icle and affected tire(s)
and rim(s) inspected by an author ized Audi
dealer. Tires that have been dr iven in the run­
flat mode must be rep laced .
& WARNING
=
Use of damaged run-flat tires and rims can
cause vehicle damage that can lead to loss
of vehicle control, a crash and serious per­
sonal injury.
- Always have the vehicle and affected
tire(s) and r im(s) inspected by an author­
ized Audi dealer after driving a tire in the
run-flat mode.
- Tir es that have been dr iven in the run­
flat mode must be replaced.

the floor so that no t ire sea lant can run out
into the veh icle.
• Place the electric air pump in the luggage
compartment for the t ime being .
• Start driv ing right away so that the sealant
is distributed in the tire.
_&. WARNING
- Follow the manufacturer's safety instruc­
tions on the decal for the air pump and
the sealan t bottle.
- If a tire pressure of 1.8 bar cannot be
achieved after pumping for 5 minutes,
the tire is too severe ly damaged. Do not
continue to drive.
- Seek professional assistance if it is not
possible to repair the tire with the tire
sealant.
(D Tips
- Do not operate the electric air pump for
more than 6 minutes without stopping,
otherwise it can overheat . When the air
pump has cooled down, you can continue
to use it.
- If sea lant has escaped, allow it to dry,
then you can pee l it off.
Final check
App lies to vehicles: wit h Tire Mobility System
After driving for a short distance, tire
pressure must be checked
• After driving for about 10 minutes, stop and
check the tire pressure .
• If tire pressure is still at least 1.3 bar, in­
flate the tire to specified pressure (see driv­
ers side B-pillar), drive to the next repa ir
shop and have the tire and the sealant bot­
tle replaced.
• If tire pressure is less than 1.3 bar, the tire
is too severely damaged. Do not continue to
drive . Seek professional assistance. .,.

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
difficult to replace vehicle light bulbs since in
many cases, other parts of the car must first
be removed before you are able to get to the
bulb . Th is appl ies especially to the l ight bulbs
in the front of your car which 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
must be co rrectly taken apart and then prop­
e rly 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 author ized Audi dealer replace any bulbs
for you, since your dealer has the proper tools,
the correct bu lbs and the expertise.
Gas disc harg e la mps (X enon l ig ht s}*:
Due to the high electrical voltage, have the
bulbs replaced by a qualified technician.
Headlights with Xenon light can be identified
by the high voltage sticker.
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 tra ining, 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.
@ Tips
- If you must replace the light bulbs your­
self, a lways remember that the eng ine
compartment of any vehicle is a hazard­
ous area to work in. A lways read and
heed all WARNINGS
¢page 165, Work­
ing in the engine compartment¢.&..
-It is best to ask your authorized Audi
dealer whenever yo u 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
g ine.
Jumper cables
Use only jumper cables of sufficiently
largecross section to safely carry the starter
current. Refer to the manufacturer's specifica­
tions.
Use only jumper cables which have
insulated
termina l clamps and are properly marked for
distinction :
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black.
_& 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 you r eyes and avoid lean­
ing over the battery whenever possible.
Emergency situations 21 7
-A discharged battery can already freeze
at temperatures just below 32 °F (0 °C).
Before connect ing a jumper cable, the
frozen battery must be thawed com­
pletely, 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 explosion.
- Vehicle batter ies generate explosive gas­
es. Keep sparks, flame and lighted c iga­
rettes away from batteries.
- Do not try to jump start any veh icle w ith
a low ac id 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 diff erent voltage
or substantially different "Ah" rat ing
may cause an exp losion and personal in­
jury.
- 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 batter ies of different voltage or
substantially different capacity (Ah) rat ­
ing may cause an exp losion and injury .
The ca pa city (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
c::;,page 165, Working in the
engine compartment.
(D Note
- App lying a higher voltage booster bat­
tery will cause expensive damage to sen­
sit ive electronic components, such as
control units, relays, rad io, etc .
- There must be no electrical contact be­
tween the vehicles as otherwise current
could already start to flow as soon as the
posit ive(+) terminals are connected. ..,. •

218 Emergency situations
@ Tips
The discharged battery must be properly
connected to the vehicle's electrical sys­
tem.
Use of jumper cables
Make sure to connect the jumper coble
clomps in exactly the order described below!
Fig. 165 Engine compart ment: Co nnectors for jumper
cables and charger
Fig. 166 Jump starting with the battery of another ve­
hicle: @discharged veh icle batte ry,® booste r battery
The procedure described below for connecting
jumper cables is intended to provide a jump
start for your veh icle.
Preparatory measures
1. Do not jump start a frozen battery! Re­
place such a battery!
2 . Otherwise apply the hand brake and put
the selector lever into P position.
3. For both vehicles switch off all consumers
and the ign ition.
Connecting/disconnecting the jumper
cable .
4. Connect one end of the red jumper cable
on the
jump start bolt@q fig. 166
(Bolts under red cover = "positive") of the
vehicle to be started @.
5. Connect the other end of the red jumper
cable to the positive terminal @of the
booster battery @.
6. Connect one end of the black jumper ca­
ble to the negat ive terminal @of the
booster battery @.
7. Connect the other end of the black jumper
cable to the negative terminal (bolt head)
@ in the external start ing point @ of
your vehicle.
8. Route the jumper cables so that they can­
not catch in any rotating parts in the en­
gine compartment.
Starting the engine
9. Start the engine of the vehicle providing
assistance and allow it to run at id le .
10. Now start the engine of the vehicle with
the discharged battery, wait for two to
three minutes until the engine "runs"
smoothly.
11. If the eng ine does not start: Stop try ing
after 10 seconds and then try again after
about 30 seconds.
12. In the vehicle that has received start as­
sistance, turn on the heater blower and
the rear window heating to elim inate any
vo ltage peaks when disconnecting . Driv­
ing lights must be switched off!
13 . Disconnect the cable while the engine is
running exactly in
reverse order to that
described in¢
page 218, Connecting/dis­
connecting the jumper coble ..
When do­
ing so, make sure that the cable cannot
contact rotating eng ine parts.
14. Close the cover on the positive terminal.
The battery is vented to the outside to prevent
gases from entering the vehicle inter ior. Make
sure that the jumper clamps are well connect­
ed with their
metal parts in full contact with
the battery terminals.
A WARNING ~
To avoid serious personal injury and dam-
age to the vehicle, heed all warnings and
