- Always make sure that the rear seat backrest to which the center rear safety
belt* is attached is securely latched
whenever the rear center safety belt is
being used to secure a child restraint.
- If the backrest is not securely latched, the child and the child restraint will be
thrown forward together with the back­ rest and will strike parts of the vehicle
interior. The child can be seriously in­
jured or killed.
- Never install rear-facing child safety
seats or infant carriers on the front pas­
senger seat. A child will be seriously in­
jured and can be killed when the passen­ ger airbag inflates.

tion.
- An improperly installed child restraint
can interfere with the airbag as it de­
ploys and seriously injure or even kill the
child.
-Always carefully follow the manufactur­
er's instructions provided with the child
safety seat or carrier.
- After checking to make sure that the child restraint is properly installed, make
certain that the child restraint is correct­ ly recognized by the capacitive passenger
detection system in the front passenger
seat and that the
PASSENGER AIR BAG
OFF
light signals the correct front pas­
senger frontal airbag status.
& WARNING
-Forward-facing child restraints:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
- Never put the forward-facing child re­
straint up, against or very near the in­
strument panel.

-Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible before installing
the forward-facing child restraint. The
backrest must be adjusted to an upright
position.
- Make sure that the
PASSENGER AIR BAG

could beg in t o slide on top of the water
(aq uaplaning). If this sho uld occur, you

Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting
the engine.
If a vehicle with a conventional energy system
is not driven for a long period of time, the bat­
tery is d ischarged by idling current consumers
(e.g . immobilizer) . In certain circumstances it
can result in there being insufficient energy
avai lab le to start the engi ne .
Intell igent energy management in your veh i­
cle hand les the d istribution of electrical ener­
gy. Starting ab il ity is markedly improved and
the life of the battery is extended .
Basically, energy management consists of
battery diagno sis, idling curr ent manage­
ment
and dynami c energ y man agement .
Battery diagno sis
Battery diagnosis continuously determines
the state of the battery. Sensors determ ine
battery vo ltage, battery current and battery
temperature . This determ ines the current
state of charge and the powe r of the battery.
Idling current man agement
Idling current management reduces energy
consumption while the vehicle is stand ing.
W ith the ignition switched off, it contro ls the
energy supply to the various electr ical compo­
nents . Data from battery diagnosis is consid­
e red. Depend
ing on the battery's state of cha rge ,
individua l consumers are g radually turned off
to prevent excessive discharge of the battery and th us maintain starting capability.
Dynamic energy manag ement
While the vehi cle is being d riven, dynamic en ­
ergy management distributes the energy gen ­
erated accord ing to t he needs of the individ u­
al components . It regulates consumption, so
that more electrical energy is not being used
than is being generated and ensures an opti­
mal state of charge fo r the battery .
(D Tips
-But even energy management cannot
negate the limits of physics. Consider
tha t the powe r and life of a battery are
limited.
- If start ing ability is threatened , the indi­
cator light
(•i appears r:::;, 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 year . Abundant electrical energy is re­
quired, but on ly a little is generated . It is also
c rit ical if the engine is not r unning and e lectri­
ca l components are tu rned on . In this in­
sta nce ene rgy is be ing consumed b ut none is
being gene ra ted.
It is in prec isely these s ituations that you will
notice ene rgy management a ctive ly regu lat­
i ng t he d istribu tion of ene rgy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks, electr ica l compo­
nents a re g radually cut back or sw itched off.
T h is reduces energy consumption and ma in­
ta ins start ing capability over a longer pe riod .
Some of the convenience func tions may not
opera te, such as the interio r lights or the
power seat adjustment. The convenience
ll-

functions will be available again when you
switch on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for example, with
the eng ine turned off or use othe r MM I fu nc­
tions, the battery is being discha rged.
I f starting capability is jeopardized due to en­
e rgy consumpt ion, the fo llow ing warning ap­
pears in the MMI disp lay :
Plea se start the eng ine soon or th e sys tem
w ill b e turn ed off .
The warning ind icates that the system will be
turned off automatically after 3 m inutes . If
you wish to cont inue us ing the functions , you
have to start the engine.
With the engine running
Although electrical energy is generated when
the vehicle is be ing driven, the battery can be­
come discharged . Th is happens mostly when
little energy is be ing generated and a great
deal consumed and the battery's state of
charge is no t optimal.
To br ing the energy balance back into equili ­
b rium, consumers which require especially
l arge amounts of energy are tempo rarily cut
back or swit ched off. Heating systems in par­
ticular requ ire a g reat dea l o f energy. If you
notice, fo r example, that the heated seats* or
the heated rear window are not heating, they have been temporari ly cut back or switched
off. These systems will be ava ilab le again as
soon as the energy balance has been 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 itiona l energy required is gener­
ated and the battery is charged.

214 Cleaning and protection
-When cleaning your safety belts, inspect
them for damage.
If you discover dam­
age, see your Audi dealer .
- Always read and heed all WARNINGS and
other information
c> page 204.
Engine compartment
Be especially careful when cleaning the en­
gine compartment.
Always switch off the ignition before clean­
ing the engine
c> .&..
Plenum panel
Remove leaves from the plenum pane l in front
of the windsh ield under the engine compart­
ment. This prevents the water dra in ho les
from becoming blocked, and it prevents de­
bris from entering the vehicle interior through
the heating and venti lation ducts .
Corrosion protection
The engine compartment and transmission
have been corrosion -protected at the factory.
Good ant i-corrosion treatment is very impor­
tant, particularly in the winter. If the veh icle
is frequent ly driven on salt treated roads , the
enti re engine compartment and plenum panel
should be tho roughly cleaned at the end of
winter and retreated to prevent sa lt damage.
At the same time, the underside of the vehicle
should be washed as we ll.
If the engine compartment is cleaned at any
time with grease removing solutions
1l, or if
you have the engine washed, the anti-corro­ sion treatment is a lmost always removed as
well. It is therefore essential to have a long­ lasting corrosion protection reapplied to all
surfaces, seams, joints and components in the
engine compartment .
1l Use o nly the co rrect cle anin g so lu ti on s. Ne ver use gas­
o lin e or d ie se l fuel.
A WARNING
Be aware: The eng ine compartment of any
motor vehicle is a potentially hazardous
area .
- Before work ing in the engine compart­
ment, be sure to read the information
c> page 220.
-Before reach ing into the front panel, al ­
ways sw itch off the ignition . Otherwise,
the windshield wiper system could unin­
tentionally be switched on, possibly
causing personal injury from the moving
wiper linkage .
- Never reach into the area around or
touch the radiator fan. The auxiliary fan
is temperature controlled and can sw itch
on suddenly -even when the ignition is
off.
- Do not wash, wax or dry the engine with
the engine running . Moving or hot parts
could injure you.
- Do not clean the underside of the chas­
sis, fenders, wheel covers, or other hard
to reach parts without protecting your hands and arms . You may cut yourself on
sharp-edged metal parts.
