& 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.

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.

Replacing bulbs
F or your safety, we recommend that you have your autho­
ri zed Audi dealer replace any bulbs for you.
It is becoming increasingly more and more diff icult to rep lace vehicle
ligh t bulbs since in many cases, other parts o f the car must fi rst be
removed before yo u are able to get to the bulb . This applies especially
to the light bu lbs in the front of your car which you can on ly reach
throug h the engi ne compartment .
Sheet meta l and bu lb holders can have sharp edges that can ca use
ser ious cuts, parts must be co rrectly t aken ap art and the n properly
put back together to he lp prevent breakage of parts and long term
d am age fro m water t hat c an enter housings that have no t been p rop­
erly resea led.
For your safety, we recommend that you have you r authorized Audi
dealer replace any bulbs fo r you, since yo ur dealer has t he p roper
too ls, the correct bu lbs and the expertise.
Gas discharge lamp s (Xenon light s)* :
Due to the high electr ica l voltage , have the bulbs replaced by a qual­
ified technicia n. Hea dlights w ith Xenon light are ident ified by the
high voltage sticker .
& WARNING
Changing Xenon lamps w ithout the necessary equipment can
cause serious personal injury.
• Bulbs are pressur ized and can explode when being changed.
Potential risk of injury !
• On vehicles equipped with gas discharge bulbs (Xenon light )*
lif e-threatening injurie s can re sult from improper handling of the
high- voltage port ions of such lamps ! .,_
