Care and cleaning


ZA\ WARNING
—To reduce the risk of accidents, only wash
the vehicle when the ignition is off and fol-
low the instructions from the car wash oper-
ator.
—To reduce the risk of cuts, protect yourself
from sharp metal components when wash-
ing the underbody or the inside of the wheel
housings.
— After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the winter. This in-
creases the risk of an accident. The brakes
must be dried with a few careful brake appli-
cations.

() Note
— If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Power folding exterior mirrors* must only
be folded in and out using the power folding
function.
—To reduce the risk of paint damage, do not
wash the vehicle in direct sunlight.
—To reduce the risk of damage, do not wash
decorative decals* with a pressure washer.
—To reduce the risk of damage, do not wash
the power top* with a pressure washer.
—To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges, or similar items.
— When washing matte finish painted vehicle
components:
— To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
— Never use protective wax. It can destroy
the matte finish effect.
— Do not place any stickers or magnetic
signs on vehicle components painted with
matte finish paint. The paint could be
damaged when the stickers or magnets
are removed.
(@) For the sake of the environment
Only wash the vehicle in facilities specially de-
signed for that purpose. This will reduce the
risk of dirty water contaminated with oil from
entering the sewer system.

Fuses and bulbs

long term damage from water 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 voltage, have the bulbs
replaced by a qualified technician. Headlights
with Xenon light are identified by the high volt-
age sticker.
LED headlights*
LED headlights require no maintenance. Please
contact your authorized Audi dealer if a bulb
needs to be replaced.

ZA\ WARNING
Changing Xenon lamps without the necessary
equipment can cause serious personal injury.
— Bulbs are pressurized and can explode when
being changed. Potential risk of injury!
— On vehicles 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 quali-
fied workshop should change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the
bulb holders that can cause serious cuts. If
you are uncertain about what to do, have the
work performed by an authorized Audi deal-
er or qualified workshop. Serious personal
injury may result from improperly per-
formed work.

@ Tips
—If you still prefer to replace the light bulbs
yourself, be aware that the engine compart-
ment is a hazardous area to work in > A\ in
General information on page 304.
—Itis best to ask your authorized Audi dealer
whenever you want to change a bulb.
