& 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 l~ad
particles get on your skin or clothing. Shield your eyes . Explosive
gases can cause blindness or other injury.
• Battery acid contains sulfuric acid. Sulfuric 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, immedi·
ately 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 negative cables.
& WARNING (co ntinued )
• 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 system, disconnect the
negative ground cable.
• Before performing any work on the electrical system, switch
off the engine and ignition as well as any electrical equipment.
The negative cable on the battery must be disconnected. If you are
just going 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! Otherwise you will set
off the alarm.
• When disconnecting the battery, first disconnect the negative
cable and then the positive cable.
• Before reconnecting the battery, make sure all electrical
consumers are switched off. Reconnect the positive cable first and
then the negative cable. Never interchange the cables· this could start a fire!
• Never charge a frozen or a thawed-out battery. It could
explode! If a battery has frozen , then it must be replaced. A
discharged battery can freeze over at 32°F (0°C).
• Make sure the vent hose is always attached to the opening on
the side of the battery .
• Never use batteries which are damaged . There is the danger of
an explosion! Always replace a damaged battery. _,.

& WARNING
Incorrect tire pressures and/or underinflation can lead sudden tire
failure, loss of control, collision , serious personal injury or even
death.
• When the warning symbol appears in the instrument
cluster, stop and inspect the tires .
• Incorrect tire pressure and/or underinflation can cause
increa sed tire wear and can affect the handling of the vehicle and
stopping ability.
• Incorrect tire pressures and /or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation ,
causing loss of vehicle control.
• The driver is responsible for the correct tire pressures for all
tires on the vehicle. The applicable pressure values are located on
a sticker on the driver's side B·pillar.
• Only when all tires on the vehicle are filled to the correct pres­
sure , the ti re pressure monitoring system* can work correctly.
• The use of incorrect tire pressure values can lead to accidents or
other damage. Therefore it is essential that the driver observe the
specified tire pressure values for the tires and the correct pres­
sures for the function of the tire pressure monitoring system*.
• Always inflate tires to the recommended and correct tire pres­
sure before driving off.
• Driving with underinflated tires bend more, letting them get
too hot resulting in tread separation, sudden tire failure and loss
of control.
• Excessive speed and/overloading can cause heat build-up,
sudden tire failure and loss of control.
• If the tire pressure is too low or too high, the tires will wear
prematurely and the vehicle will not handle well.

& WARNING
• If the tir e pres sure indicator appears in the instrument cluster
display, one or more of your tires i s significantly under-inflated.
Reduce your speed immediately and avoid any hard steering or
braking maneuvers. Stop as soon a s possible and check the tires
and their pressures . Inflate the tire pressure to the proper pres­
sure as indicated on the vehicle 's tire pressure label=>
page 300.
Driving on a significantly under -inflated tire causes the tire to
overheat and can lead to tire failure. Under -inflation also is likely
to impair the vehicle's handling and stopping ability.
& WARNING (co ntinued )
• The driver is re sponsible for maintaining the correct tire pres­
sures . You must check the tire pres sures regularly .
• Under certain conditions (such as a sporty driving style , winter
conditions or unpaved roads) , the pressure monitor indicator may
be delayed.
• Ask your authorized Audi dealer if run-flat tires may be used on
your vehicle . Your vehicle registration becomes invalid if you u se
the se tires when not permitted. Damage to your vehicle or acci­
dents could also result.

& WARNING (continued)
• Make sure that passengers wait in a safe place away from the
vehicle and well away from the road and traffic.
• To help prevent the vehicle from moving suddenly and possibly
slipping off the jack, always fully set the parking brake and block
the wheel diagonally opposite the wheel being changed with the
folding chocks or other objects. When one front wheel is lifted off
the ground, placing the Automatic Transmission in "P" (Park) will
not prevent the vehicle from moving.
• Before you change a wheel, be sure the ground is level and
firm. If necessary, use a sturdy board under the jack.

F or your safety, we recomm end that you have your autho ­
riz ed Audi dealer replace any bulbs for you .
It is becoming increasing ly mo re and more d ifficult to replace vehicle
light bulbs since in many cases, other parts of the car must f irst be
removed before yo u are ab le to get to the bu lb. This app lies especially
to the light bulbs in the front of your car which you can only reac h
t hrough the eng ine comp artment.
Sheet metal and bu lb holders can have sharp edges that can cause
serious c uts, parts must be correctly taken apart and then properly
put back together to he lp prevent breakage of parts and long term
damage from water t hat can enter housings that have not been prop­
erly resea led.
For your safety, we recommend that you have your authorized Audi
dealer replace a ny bu lbs for yo u, since yo ur dealer has the proper
too ls, t he cor rect bu lbs and the expertise.
Gas discharge lamps (Xenon lights)*:
•
Due to the high electrical voltage, have the bulbs replaced by a qua l­
ified techn ici an . Hea dligh ts w ith Xenon light are i dent ified by t he
hig h voltage sticker.
& WARNING
Changing Xenon lamps without the necessa ry equipment can
c aus e seriou s personal injury.
• Bulbs are pressurized and can e xplode when being changed.
Potential risk of injury!
• On veh icle s equipped with gas discharge bulbs (Xenon light)*
life-threatening injuries can result from improper handling of the
high- voltage portions of such lamps!
• Only your authorized Audi dealer or a qualified workshop
should change the bulbs in gas discharge lamps. There are parts
with sharp edges on th e openings and on the bulb holder s 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 . Serious personal injury m ay result from improperly
performed work.
[ i ] Tips
• If yo u still p refer to rep lace the l igh t bul bs yourself, be aw are t hat
the engine compartment is a hazardous area to work in~
page 272,
"En gine compartment" ~& .
• It is best to ask your authorized Audi dealer whenever you want to
c h ange a bulb. •
