118 Audi sid e as sist
- Improper reliance on the side ass ist sys­
tem can cause co llisions and serious
persona l injury:
- Never rely only o n side assist when
ch anging lanes.
- Always check rear view m irrors to make
sure that it is safe to change lanes.
- Side ass ist cannot detect a ll vehicles un­
der all cond it ions -danger of ac cident!
- Please note that side assist indicates
there are approachi ng veh icles, o r
vehicles in your blind spot, on ly afte r
yo ur vehicle has rea ched a driving speed
of at least 19 mph (30 km/h).
- In certain s ituations, the system may not
f unc tion o r its fun ct io n may be lim ite d.
For example:
- if veh icles are approaching or being left
behind very quick ly . The display may
not turn on in time.
- in poor weather co ndit ions such as
heavy ra in, snow or heavy m ist .
- on very wide lanes, in tight curves or if
there is a rise in the road surface.
Vehicles in the adjacent lane may not be detected because they are outside
of the sensor range.
(D Note
The sensors ca n be displaced by impacts or
damage to the bumpe r, wheel housing and
unde rbody . This can affect the system.

There are some important things you have to know to make sure that the effectiveness of
the system will not be impaired and that dis­
carded components do not cause injury or pol­
lute the environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag from deploying when needed or deploying an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way.
- Never attach any objects such as cu­
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc.) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work­
shop.
- Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
Airbag system 171
-Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it
must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only
once. After an airbag has been deployed, it must be replaced with new replace­
ment parts designed and approved espe­
cially for your Audi model version. Re­ placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only.
Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- In accidents when an airbag is deployed,
the vehicle battery separates the alterna­
tor and the starter from the vehicle elec­
trical system for safety reasons with a
pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified dealer - risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.
{® For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate Material -special handling may apply, see

204 Intelligent technology
With the engine turned off
If you listen to the radio, for example, with
the engine turned off or use othe r MMI* func­
tions, the battery is being discharged .
If sta rting capability is jeopardized due to en­
e rgy consumption, the following warning ap­
pears in the radio or MMI* display:
Please start engine, otherwise system will
switch off in 3 minute s.
The warning ind icates that the system will be
turned off automatically after 3 m inutes .
If
you wish to continue using the functions , you
have to start the engi ne.
With the engine running
Although electrical energy is generated when
the vehicle is being driven, the battery can be­
come discharged . This happens most ly when
l ittle energy is be ing generated and a great
deal consumed and the battery's state of
cha rge is not optimal.
To br ing the energy balance back into equili­
brium, consumers which require especially
l arge amounts of energy are tempo rari ly cut
back or switched off. Heating sys tems in par­
ticular requi re a great dea l of energy . If you
notice, for example , that the heated seats* or
the heated rear window are not heating, they
have been temporar ily cut back or switched
off. These systems will be ava ilable again as
soon as the energy balance has bee n restored.
You will a lso notice that engine idle speed has
been increased slightly. This is norma l and not
a cause for concern . By increasing engine idle
speed the add itional energy required is gener­
ated and the battery is charged .

& WARNING
Too much undercoating in the wrong pla­
ces can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exha ust
manifold, exhaust pipes, cata lytic con­
verter or heat shie lds . Wh ile driving, the
substance used for undercoating could overheat and cause a f ire.
- Always read and heed all WARNINGS and other information
c:> page 216.
Exhaust tail pipes
-
Road sa lt and other corros ive materia ls will
damage the mater ial in the exhaust tail p ipes
if they are not cleaned regula rly . Do not clean
the ta il p ipes with whee l cleaner, paint polis h,
chrome polish or othe r abrasive cleane rs.
C lean the tail p ipes wi th car care prod ucts
that are s uitab le for stain less stee l.
Your authori zed Audi dealer can provide clean­
in g p roducts t hat have been tested and ap­
p roved for you r vehi cle.
Care of interior
Radio and MMI* display
.,. Clean the d isp lay w ith a soft clea n cloth and
an LCD cleane r.
The display can be cleaned w ith a professio­
na lly available "LCD cleaner". The cloth shou ld
be slightly dampened with the clean ing flu id
to clean the display .
(D Note
To avoid scratching the display, you should
never clean it dry .
MMI control console
Applies to vehicles: with MMI
.. First clean the MMI control console with a
brus h to remove dust from the hous ing .
.,. The n w ipe the MMI con tro l c onso le w ith a
cl ean, soft, s ligh tly damp cloth .
Cleaning and protec tion 223
The M MI contro l console sho uld be cleaned
with a brush first so that no dirt is t rapped be­
tween the buttons and the housing . We rec­
ommend giving the MMI control conso le a fi ­
nal wipe with a cloth moistened with water
and dish washing detergent .
(D Note
To prevent damage, make s ure that no flu­
i d ever gets into t he MMI contro l conso le.
Aluminum trim
Use only neutral-pH products to remove spots
and deposits from aluminum surfaces .
Chrome care products a nd a lkaline cleaners
will attack a luminum surfa ces and ca n dam­
age them over t ime .
& WARNING ~
Always read and heed all WARN INGS and
other info rmation
c:> page 216.
Fabrics and fabric coverings
Fabrics and fab ric coverings (e.g . seats, door
trim pane ls, etc .) sho uld be cleaned at regular
intervals w ith a vacuum cle aner. This removes
su rface dirt particles which could become em­
bedded in the fabric through use . Steam
cleaners sho uld not be used , because the
steam te nds to p ush the dirt deeper into the
fabric and lo ck it the re.
Normal cleaning
Generally, we recommend us ing a soft sponge
o r a lint -free microfibe r clo th to t he clean fab ­
r ic. B rushes s hou ld only be used for carpets
and floo r mats, since othe r fabr ic surfa ces
cou ld be harmed by br ushes.
Normal su rface stains can be cleaned using a
comme rc ially availab le foam cleaner . Spread
the foam o n the su rface of t he fabric with a
soft sponge and wo rk it in gently . D o no t satu ­
ra te the f abric. Then pat the foam dry using
absorbent, dry cloths (e .g . m icrofi ber cloth)
and vac uum it after it has dried compl etely .

The oil level needs to be checked at regular in­
tervals . The best times to do this are whenev­
er you refuel and prior to long trips .
Depending on the way the vehicle is driven
and the operating conditions, oil consumption
can be up to a 1/2 quart per 600 miles (0.5
li­
ter per 1,000 km). Consumption may be high­
er within the first 3,000 miles (5,000 km).
@ Tips

A discharged battery can freeze at tempera­
tures of on ly 32 °F (0 °C). A llow a frozen bat­
tery to thaw completely befo re attempt ing to
cha rge it~ &. . H owever, we recommend not
using a thawed battery again because the bat­
tery casing can be cracked due to ice forma ­
tion and can leak battery acid.
Battery charging (Maximum charging rate
of
30 amps/14.8 Volt)
When charging at low voltages (e.g . with a
trickle charger ), the battery cables do not
have to be d isconnected first. The battery
caps should
not be opened when charging a
battery .
It is not necessary to remove the battery from
the luggage compartment.
Fast charging the battery (charging rate
above 14.8 Volts )
For technical reasons do not use a battery
charger that uses voltage greater than 14.8
Volts to charge your vehicle's battery.
.&_ WARNING
Charging a battery can be dangerous. -
Always follow the operating instructions
provided by the battery charger manu­
facturer when charging your battery.
- Never charge a frozen battery. It may ex­
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out first.
- Do not reuse batteries wh ich were fro­
zen. The battery housing may have
cracked and weakened when the battery
froze.
- Charge the battery in a well ventilated
area. Keep away from open flame or elec­
tr ica l spark. Do not smoke. Hydrogen gas
generated by the battery is explosive.
- To reduce the danger of explosion, never
connect or disconnect charger cab les
while the charger is ope rat ing.
- Fast charging a battery is dangerous and
should only be attempted by a compe­
tent technician with the proper equip­
ment.
- Battery acid that may spill dur ing charg­
ing should be washed off with a solution
of warm wat er and baking soda to neu­
tralize the acid.
(I) Note
Never use a fast charger as a booster to
start the engine. This will seriously dam­
age sensitive electronic components, such
as contro l units, re lays, radio, etc., as well
as the battery charger.
Battery replacement
The new battery must have the same specifi ­
cations and dimensions as the original equip ­
ment battery.
Intelligent energy management in your vehi­
cle is responsible for distributing the electri­
ca l energy throughout your vehicle
¢
page 203 . The intelligent energy manage­
ment system will keep the engine battery
charged better then vehicles without this sys­
tem . To make sure the additional electrical en­
ergy is ava ilable once again after you have
changed the battery, we recommend that you ..,.

-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .
