same kind of child rest raint offered by child
restraint manufact urers.
The weight ranges fo r the ind ividual types,
makes and mode ls o f chi ld restra ints that the
NHTSA has specified in the Safety Standard
together with the weight ranges of typical in­
fants and typical 1 year-o ld child have been
stored in the control unit of the Advanced A ir­
bag System. When a child restraint is being
used on the front passenger seat with a typi­
cal 1 year-old ch ild, the Advanced Airbag Sys­
tem compa res the we ight measured by the
weight sensing mat with the informat io n sto r­
ed i n the ele ct ron ic cont ro l uni t.
The electron ic control unit also registers the
tension on the front passenge r safety belt .
The tens io n on the safety be lt fo r the front
passenger seat will be d iffe ren t for an ad ult
who is prope rly using the safety belt as com­
pared to the tension on the be lt whe n it is
used to attach a chi ld restraint to the seat.
The sensor below the latch for the safety be lt
for the front seat passenger meas ures the
tension on the be lt. The input from this sen­
sor is then used with the we ight to "decide",
whether there is a ch ild restraint w ith a typ ical
1 year-o ld child o n the front passenger seat
and whe ther or not the ai rbag must be tu rned
off.
Child restraints and Advanced Airbags
Regardless o f the child restraint t hat you use,
make sure that it has been ce rtified to meet
United States Federal Motor Vehicle Safety
Standards and has been certified by its manu­
facturer for use with a n airbag. Always be sure
that the child restraint is properly instal led at
one of the rear seat ing pos itions .
If in excep­
tional c ircumstances you must use it on the
fro nt passenger sea t, caref ully read all of the
i n format ion on c hild safety and Advanced A ir­
bags and heed a ll of the app licab le WAR N­
I NGS . Ma ke certain that the child restraint is
correctly recognized by the weig ht-sensing
mat inside the front passenger seat, that the
fro nt passenger airbag is turned off and that the a
irbag sta tus is always cor rect ly signa led
by the
PASSENGER AIR BAG OFF light .
Many types and models of child res traints
h ave been available over the yea rs, new mod­
els are introduced regu larly incorporating new
and improved designs and o lde r mode ls are
ta ken out o f product ion . Ch ild restra ints are
not standard ized . Child restraints of the same
type typically have different weights and sizes
and different 'footpr ints,' the size and shape
of the bottom of the ch ild restra int that sits
on the seat, when they are insta lled on a vehi­
cl e seat. These d iffe rences make it v irtually
i mpossible to certify compl ian ce wi th t he re­
quiremen ts for advanced airbags with eac h
and every chi ld restraint that has eve r been
sold in the past or wi ll be sold over the course
of the useful life of your veh icle.
F or t his reason, the United S tates National
Highway T raffic Safety Adm inist ration has
published a list of specific type, ma kes and
models of child restraints that must be used
to certify comp liance of the Advanced Airbag

-On wet road surfaces , be careful not to
dr ive too fast because the front wheels
cou ld beg in to slide on top of the water
(aquaplaning). If this should occur, you
will have no warning from a sudden in­
c rease in engine speed as with a front­
wheel drive vehicle. A lways d rive at

Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimi zes the
availabili ty of elec trical energy for s tarting
t he engine.
If a vehicle with a conventional energy system
is not driven for a long period of time, the bat­
te ry is d ischarged by idling current consumers
(e.g . immobilizer) . In certain ci rcumstances it
can result i n there bei ng ins ufficient ene rgy
ava ilab le to start th e engi ne .
Intell igen t energy management in y our veh i­
cle hand les the d istribution of electrical ener­
gy. Starting ab ility is markedly improved and
the life of the battery is extended .
Basically, energy management consists of
battery diagnos is , idling current manage­
ment
and dynamic en ergy management .
Battery diagnosis
Battery d iagnosis continuously determ ines
the state of the battery. Sensors determ ine
battery vo ltage, ba tte ry current and battery
temperature . This dete rm ines the current
state of charge and the powe r of the battery.
Idling current management
Idling current management reduces energy
consumption while the vehicle is stand ing.
W ith the igni tion switched off, it cont ro ls the
energy s upply to the va rious e lectr ica l compo ­
n ents . Data from battery diagnosis is consid­
e red. D
epend ing on the ba tte ry's state o f cha rge ,
indivi dual cons umers a re g radually turned off
to prevent excessive discharge of t he battery
and th us maintain starting capability.
Dynamic energy management
While the vehi cle is being d riven, dynami c en ­
ergy management distr ibutes the energy gen ­
erated accord ing to t he needs of the indivi du­
al components . It regulates consumption, so
t h at more electrical energy is not being used
t h an is be ing generated and ensures an opti­
mal state of charge fo r the battery .
(D Tips
-But even ene rgy management cannot
negate the limits of physics. Consider
t ha t the powe r and life of a battery are
limited.
- If start ing ability is t hreatened , the indi­
cator light(•) appears ~
page 17.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severe ly taxed in short-d istance
driv ing, in city traff ic and during the cold time
of yea r. Ab undant electrical e nergy is re­
quired, but on ly a little is generated . It is also
c rit ical if th e engi ne is no t ru nning and e lectri­
ca l c ompone nts are t urned on . In this in ­
sta nce ene rgy is be ing consumed but none i s
being gene ra ted .
It is in prec isely these s ituations that you will
not ice ene rgy management a ct ive ly reg ulat­
in g t he di stribu tion of ene rgy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of seve ral days or weeks , e lectr ica l compo­
n ents a re g radually cut bac k or sw itched off.
T h is reduces energy consump tion and ma in­
ta in s start ing c apabili ty over a longer pe riod .

(D Note
-Never try to remove dirt, mud or dust if
the surface of the vehicle is dry. Never
use a dry cloth or sponge, since this
could scratch your vehicle's pa int or w in­
dows .
- Never wash your car in bright sunlight.
Drops of water act as magnifying lenses
and may damage your paint.
- When you wash your car in the w inter: if
you r inse your vehicle w ith a hose, be
careful not to aim the stream of water
direct ly at locks, or at door or hatch
openings - they can free ze shut.
- Never use sponges des igned to remove
i nsects, or any kitchen scouring sponges
or similar products. They can damage
you r paint finish.
- Never use a dry cloth o r sponge to clean
the headligh ts. On ly use we t cloths or
sponges to prevent scratches.
It i s best
to use soapy wate r.
- You sho uld remove debris (su ch as in­
sects) from the head ligh t lenses on a
r egular basis, for example when refuel ­
ing your vehicle . Never use a dry cloth or
sponge to clean the head lights. Only use
wet cloths or sponges to prevent
scratches.
It is best to use soapy water.
@ For the sake of the environment
On ly wash the vehicle in facilit ies specially
designed for that purpose. Th is w ill reduce
the risk of d irty water contaminated with
oil from entering the sewer system. In
some areas, wash ing vehicles outs ide of
these facilit ies is prohib ited.
Washing your vehicle with a power
washer
Cleaning the exterior of your car with a high ­
pressure power washer is safe as long as you observe a few simple rules .
~ Before us ing the powe r washe r, make sure
yo u have re ad an d u nderstood the WARN-
Cleaning and protec tion 19 1
INGS ¢ A in General information on
page 189 .
~ Always follow the operating instr uctions for
the power washer.
~ Make sure that the jet on the spray hose pro­
duces a "fan shaped sp ray" .
~ Do not hold the sp ray nozzle too close to
soft mater ials .
Never use a pow er washer to clean the power
top itself.
Keep a distance from soft materia ls s uch as
rubber hoses or insulating material as well as
sensors and camera lenses.
When cleaning the vehicle with a power was h­
er
always follow the operating instructions .
This applies part icu larly to the operating pres­
sure and the spraying d istance. Do not point
the spray d irectly at the seals around the s ide
windows, around the doo rs, on the rea r lid or
o n the powe r top. Likewise, do not po int it di­
re ct ly at tires, rubbe r hoses, insulat io n ma te ­
ria l or senso rs
¢ page 193. Hold the spray
nozzle at leas t 1.3 ft (0. 4 m) away from the
vehicle.
Do no t use a high-p ressu re power was her to
remove snow and i ce .
Do not use a jet which sprays water in a d irect
stream o r one that has a rotat ing jet.
Water temperature should not exceed 140 °F (60
°() .
A WARNING
Neve r wash t ires with a jet t hat sprays wa­
ter in a direct stream . Thi s could cause in­
v isi ble d amage to the t ire s and weaken
them, even if the spr ay is from a re lative ly
l ong dis tance and for a sho rt time. Dam­
aged and weakened tires can fail and cause
accidents and personal in jury.
([) Note
- Never use a power washer to clean the
powe r top itse lf .

192 Cleaning and protection
-To a void damaging yo ur vehicle, always
make sure that there is sufficient dis­
tance between the spray head and soft
mater ials like rubber hoses, p lastic parts
and sound-deaden ing mater ials as well
as sensors and camera lenses . Never aim
the spray head at t he same po int for a
l ong time. This also app lies to cleaning
headlights and painted bumpers . Re­
member: the cl oser the nozzle is to the
su rface o f the materia l, the greater the
stress on the mate rial.
Caring for vehicles with matte finish
paint
Ap plies to vehicles: with matte finish pa int
Vehicles with matte finish point require spe­
cial core due to the characteristics of the
poin t.
Washing by hand
To avoid damag ing the pa int when wash ing,
f irst remove dust and large particles from
your ve hicle . Insects, g rease spots and finger­
prints are best removed with a special cleaner
for matte finish paint .
Apply the product using a microfiber cloth. To
avoid damaging the paint surface, do not use
too m uch pressure.
R inse the vehicle t ho roughly with wa ter. Clean
the vehicle sta rting at the top and working to­
ward the bottom using a
neutral shampoo
and a soft mi crofiber cloth . Stop frequently to
rinse t he cloth thoroughly.
C lean the w heels and sill panels last. Use a
clean
s ponge on these areas .
R in se the veh icle tho roughly aga in and let i t
a ir dry . If there are any wa ter spots, t hey ca n
be removed using a
leather cloth.
C lean again with t he special cleaner for matte
fini sh paint
if ne cessa ry.
Removing stubborn dirt
Bird dropping s or tree sap
are best removed
with plenty of water a nd a m icrofiber cloth. You should
rinse off
ga soline re sidue immed i­
ate ly wit h plenty of water.
A WARNING
-
- Wash your vehicle only when the ign ition
is switched off to reduce the risk of a
crash.
-Always read and heed a ll WAR NINGS and
other information
c';> page 189.
(D Note
- Do not treat veh icle parts pa inted with
matte finish paint using polishing mate­
r ia ls or hard wax . These p roducts could
cause damage to the appearance or s ur­
face that cannot be repaired.
- Never use protective wax . It can destroy
the matte f inish effect .
- Do not place any stickers or magnetic
signs on vehicle parts painted with
matte finish paint . The paint could be
damaged w hen the stickers or magnets
are removed.
'
- To prevent paint damage, do not wash
the vehicle in d irect sunlight.
- To prevent damage to the pa int surface,
do not use insect remova l sponges ,
rough k itchen spo nges or sim ila r items.
- You should remove deb ris (such as i n­
sects) from the headlight lenses o n a
regu lar basis, for example w he n r efuel­
ing your vehicle . Only clea n the head­
ligh ts u sing a wet cloth or sponge, neve r
a dry one. Clean ing wi th so apy wate r is
recommended .

Power top care
The power top requires special care.
K eep ing you r top looking great and mak ing
c e rtain that it lasts a long time depend to a
great ex ten t on prope r use an d ca re. Remove .,.

bird d ropp ings as soon as possib le, since the
corrosive chemica ls in them wi ll cause the
rubber impregnat ion in your top to swell and
possibly allow the fabric to leak.
With
normal soiling , all yo u need to do is
clear the top with a soft brush and clear wa­
ter . Always brush in the direction of the fabric
from front to rear.
If the top is
very dirty and has spotted areas
clean it with a brush using a convertible top
cleaner . Always brush in the direction of the
fabric from front to rea r. Rinse w ith plenty of
clear water, and allow the top to air-dry .
Chamo is are not suitable for drying the top .
Never use gasoline, spot remover, benze ne,
pa int thinner or so lvents to remove spo ts. We
recommend that you only use cleaners espe ­
cially formu lated for use on convertible tops ,
and that you follow the produce use di rections
caref ully. Authori zed A udi deals can p rovide
deta iled information.
A WARNING
Always read and heed all WARNINGS and
the information on ¢
page 189.
Never use a high-pressure power washer to
clean the power top.
Wind deflector
App lies to vehicles: with wind deflector
Clear the wind deflector with water or, if it is
heav ily soiled, a chemically neutra l cleaning
solut io n.
A WARNING
Always read and heed a ll WARNINGS and
t he information on
¢page 189.
Sensors and camera lenses
-Remove snow wi th a hand brush and remove
ice with a de-icing spray that does not con­
ta in solvents .
Cleaning and protec tion 193
- Clean the sensors (adap tive c ruise control *,
parking system *) with a cleaning so lution
that does not contain so lvents and a soft
cloth.
@ Note
- If you wash your vehicle with a press ure
washer,
- make sure there is enough d istance to
sensors in the rear bumper.
- do not clean the camera lenses and the area a round them with the p ress ure
washer.
- N ever use warm o r hot wate r to remove
snow or ice from the came ra lens . This
c ou ld cause t he lens to crack.
- N ever clean the camera lens with abra­
sive products .
Waxing and Polishing
Waxing
A good wax coating protects the vehicle paint
to a la rge ex ten t agains t the envi ronmental
f a ctors lis ted under ¢
page 189, Washing and
even against s light scratches .
You can use a liquid car wax to protect yo ur
paint as soon as one wee k afte r you r vehicle
has been delivered.
Even if you regularly use a
wa xing process in
a utomat ic car washes, we recommend that
yo u manually a pply a coat o f wax to g ive the
pain t ex tra protection, par ticu larly if water no
longer beads on t he clean paint.
P rotect plast ic body parts w ith car wax in the
same w ay as the veh icle body .
During warm weather dead insects tend to
collect on the front bumper and on the fo r­
ward a rea of the hood. They are much easier
to remove from pa int that is waxed
often .
Polishing
Polish your vehicle only if the paint has lost its
shine and the gloss cannot be brought back
with wax . ..., •
