Bulbs
General notes
Changing bulbs requires a certain degree of
practical
skill.

LED*
lights are maintenance-free and cannot be

changed.
For repairs, please contact a qualified
workshop.
If
you
decide to change bulbs in the engine com­
partment yourself, be aware of the safety risks
involved
*
A in Working on components in the
engine compartment on page 295.
WARNING
- Take particular care when working on com­
ponents in the engine compartment if the
engine is warm - risk of burns!
- Bulbs are sensitive to pressure. The glass
can break when you touch the bulb, causing
injury.
- When changing bulbs, please take care not
to injure yourself on sharp edges, in particu­
lar on the headlight housing.
© CAUTION
-Always switch off the ignition before carry­
ing out any work on the electrical system -
danger of short circuiting!
- Switch off the Lights or parking lights before
you change a bulb.
- Take good care to avoid damaging any com­
ponents.

- Make sure that the covers are correctly seat­
ed on the headlights and the rear lights.
This will ensure that water cannot enter the
housings and cause the lights to malfunc­

tion.

- Do not touch the glass part of the bulb with
your bare hands; use a cloth or paper towel

instead.
Otherwise, the fingerprints left on
the glass will vaporise as a result of the heat
generated by the bulb, be deposited on the
reflector and impair its surface.
© CAUTION
When removing or installing the rear light,
take care not to cause any damage.
- Removing the rear light in particular can
lead to the paintwork or rear light becoming

damaged.
This is another reason why we
recommend having the bulbs changed by a
qualified workshop.
- Never use metal tools (e.g. a screwdriver) or
sharp or pointed plastic tools to lever out
the rear light - risk of damaging the paint.
- Make sure you have a soft cloth ready to
place under the glass on the rear light, to
avoid any scratches.
® For the sake of the environment
A qualified workshop can advise you how to
dispose of used bulbs in the proper manner.
© Note
- Please check at regular intervals that
alL

lighting (especially the exterior Lighting) on
your vehicle is functioning properly. This is
not only in the interest of your own safety,
but also in that of all other road users.
- Before changing a bulb, make sure you have
the correct new bulb.

Accessories

Accessories
and

cations
to the
vehicle
Accessories,
replacement parts
and

repairs
Always
ask
your dealer
or
specialist retailer
for

advice before purchasing accessories
and
re­
placement parts.
Your
car is
designed
to
offer
a
high standard
of

active and passive safety. For this reason,
we
rec­
ommend that you ask your Audi dealer
for
advice
before fitting accessories
or
replacement parts.
Audi dealers have
the
latest information from
the manufacturer and
can
recommend accesso­
ries and replacement parts which
are
suitable
for

your requirements. They can also answer
any

questions you might have regarding official
regu­

lations.
We recommend you
to
use only Audi accessories
and Audi Genuine Parts. Audi has tested these
products
for
suitability, reliability and safety.
Audi dealers have
the
necessary experience
and

facilities
to
ensure that
the
parts
are
installed
properly.
Although
the
market
is
constantly scrutinised,
Audi
cannot
judge
or
assume responsibility
for

the reliability, safety and suitability
of
non-genu­
ine products
-
even though
in
some instances,
these parts
may
have been approved
by
an
offi­

cially recognised technical testing authority
or

accompanied
by
an official approval certificate.
Any retro-fitted equipment which has a direct
ef­

fect on
the
vehicle and/or
the
way
it is
driven

(e.g.
cruise control system
or
electronically-con­
trolled suspension) must
be
approved
for
use
in

your vehicle and bear
the e
mark
(the
European
Union's approval symbol).
If any additional electrical components are fit­
ted which
do not
serve
to
controL
the
vehicLe
it­

self
(for
instance a refrigerator box, laptop
or

ventilator
fan,
etc.), these must bear the C€ mark
(manufacturer conformity declaration
in the Eu­

ropean Union).

A,
WARNING

Never attach accessories (such
as cup
holders
or telephone brackets)
to the
surfaces cover­
ing
the
airbag units
or the
areas around
the

airbags: this could cause injury
if
the airbag
is

triggered.

Modifications
Modifications must always
be
carried
out
accord­
ing
to our
specifications.
Unauthorised modifications
to the
electronic
components, software, wiring
or
data transfer
in

the vehicLe may cause malfunctioning. Due
to the

way
the
electronic components
are
linked togeth­
er
in
networks, other systems
may be
affected
by

the faults. This can seriously impair safety, lead
to excessive wear
of
components,
and
also inva­
lidate
the
type approval
for
your vehicle.
You will appreciate that your Audi dealer cannot
be held liable
for
any damage caused
by
modifi­
cations and/or work performed incorrectly.
We recommend that
all
work should
be
per­
formed
by
an Audi workshop using Audi Genuine

Parts.

/K
WARNING

- Incorrectly performed modifications
or
oth­

er work
on
your vehicLe can lead
to
malfunc­
tions and cause accidents.
-
Do not
use an additional
or
replacement
number plate holder other than
the
original
one fitted
at the
front
of
the vehicle.
Radio transmitters
and

business equipment
Transmitters
An external aerial
is
required
in
order
to
operate
radio equipment inside
the
vehicle. The maxi­
mum range
of
the equipment can only
be
ach­

ieved with
an
external aerial.
Retrofit installations
of
radio transmitters
in the

vehicle
are
subject
to
official approval and can
af­

fect
the
type approval
for
your vehicle.
