~ Engine oil pressure
The red engine oil pressure warning symbol
requires immediate service or repair .
If the . symbo l appears in the disp lay and
flashes, the o il pressure is too low . In add ition
to the symbol, the followi ng message also ap ­
pears in the display :
Switch off engine! Oil pressure is too low
.. Pull off t he roa d and stop the ve hicle .
.. Shut the eng ine down.
.. Check the engine oil level¢

.. Contact your authori zed Audi dealer for as -
sistance if necessa ry.
Engine oil level too low
If the engine oil leve l is too low , top off oil to
the p roper level
¢ page 169 .
Engine oil level OK
If the . sym bo l starts flas hing ag ain even
t h o ug h t he eng ine oi l level checks OK on the

(D Tips
- The engine oil pressure symbol. is
not an indicator for a low engine oil lev­
el. Do not rely on it. Instead, check the oil level in your engine at regular inter­
vals, preferably each time you refuel, and always before going on a long trip .
- The yellow oil level warn ing indication
Ill requires oil refill or workshop serv­
ice without delay. Do not wait until the

Auto Check Control
Some f unct ions and vehicle components are
scanned for their operati ng sta tus when yo u
switch the ign ition on and whi le you a re driv­
ing. Malfunctions or req uired service proce­
dures ar e signaled audib ly and indicated by
red and yellow i lluminated symbols and re ­
m inders in the display.
A WARNING -
- Never rely exclusively on the outside
temperature display to determine if a
road surface is icy or not . K eep in m ind
that road surfaces, espec ially br idges
and overp asses, co uld be ice covered and
slippe ry even at an outside tempe ra tu re
above 4 1 °F (+5 °C).
- Always remembe r, even if the "snow­
f lake" symbo l (ice warning) does not ap­
pear in the disp lay, black ice could be on
the road .
- A lways reduce your speed and d rive with
specia l care in cold weather cond itions
when the chance of encountering icy
road surfaces increases.
(D Tips
- If the vehicle is stationary, or if you are
dr iving at a very low speed, the tempera­
t u re s hown in the d isp lay m ight be
slightly h igher than the actual o utside
temperature. Th is is caused by the heat
being radiated from the engine .
- On vehicles with Audi Nav igat ion sys­
tem *, the displays may differ from their
normal appearance during navigation .

Master key with remote control
The remote control allows you to lock or un­
lock the vehicle electronically .
The transmitter and battery are located in the
head of the remote control. The receiver is lo­
cated inside the vehicle. The maximum effec ­
tive range depends on several things . Remem­
ber, if the battery is wea k, the effective range
decreases.
If you need to replace the remote control, or if
you need to have it repaired, you must see
your author ized Audi dealer. Only then can
you use the key again.
(D Tips
- If the ignition is sw itched on, the remote
control system is deactivated .
- The remote control system can be affect­ ed by other systems operating in the
same frequency range close to the vehi­
cle, such as mobi le telephones, televi­
sion broadcasting stations, etc.

-If you must install a rearward facing
child safety seat on the front passenger
seat because of exceptional circumstan­ ces and the
PA SSE NGER AI R BAG OFF
light does not appear and stay on have
the a irbag system inspected by your Audi
dealer.
- A tight tether or other strap on a rear­
ward-fac ing child restra int attached to
the front passenger seat can put too much pressure on the weight-sens ing
mat in the seat and register more weight
than is actually on the seat. The heavier
weight registered can make the system
work as though an adu lt were on the seat
and deploy the Advanced Airbag when it
must be suppressed caus ing serious or
even fatal injury to the child .
- If, in exceptional circ umstances, you
must install a forward-facing child re­
st raint on the front passenger seat, a l­
ways move the seat into its rearmost po­
sit ion in the seat's fo re and aft adjust­
ment range, as far away from the airb ag
as possib le . The backrest m ust be adjust­
ed to an upright position. Make sure that
the
PASSENGER AIR BAG OFF light
comes on and stays on all the t ime when­
ever the ignition is switched on.
A WARNING
- If the PASSENGER AIR BAG OFF light
does not go out when an adult is sitting
on the front passenger seat after taking
the steps described above, have the air­
bag system inspected by your Aud i deal­
er before transporting anyone on the
front passenger seat.
(Di Tips
If the weight-sensing mat in the front pas­
senger seat detects an empty seat, the
front airbag on the pa ssenge r side will be
t urned off, and
PASSENGER AIR BAG OFF
w ill stay on .

Repair, care and disposal of the airbags
Parts of the airbag system are i nstalled at
many diffe rent p laces o n your Aud i. Insta llin g,
removing, servicing or repa iring a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a coll is ion.
T he re a re some important t hings you have to
know to make sure that the effectiveness o f
the system wi ll not be impaired and that dis­
carded components do not cause injury or pol ­
lute the environment.
A WARNING
Improper care, serv ic ing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an a irbag
from deploying when needed or deploying
an a irbag unexpec tedly:
- Never cover, obst ruct, or change the
steer ing whee l horn pad or airbag cover
or the inst rument panel or mod ify them
in any w ay .
- Never attach any objects s uch as c up
holders or telephone mountings to the
surfaces covering the a irbag un its .
- For cleaning the horn pad or instr ument
panel, use only a soft, dry cloth or one
mo istened with pla in water. Solvents or
cleaners could damage the airbag cover
or change the st iffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the a irbag system.
- All work on the steering wheel, instru­
ment panel, front seats or e lectr ica l sys­
tem (including the installation of audio
equ ipment, cellular telephones and CB
radios, etc.) must be performed by a
qualified technic ian who has the training
and specia l equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
author ized Audi dealer or qualified work-
shop.

Basically, energy management consists of
batter y di agno sis, idling cur rent man age­
ment
and d yn ami c en ergy m anagement.
Battery diagnosis
Battery d iagnosis continuously dete rmines
the state of the battery. Senso rs determ ine
battery vo ltage, battery current and battery
temperature. This determines the current
state of charge and the power of the battery.
Idling curre nt management
Idling c urrent management red uces energy
consumption while the vehicle is standing.
With the ignition switched off, it contro ls the
energy supply to the various electrica l compo­
nents . Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
individua l consumers are grad ually turned off
to prevent excess ive d ischarge of the battery
and thus mainta in start ing capability.
Dynam ic energ y manag em ent
While the vehicle is being driven, dynamic en ­
ergy management distributes the energy gen­
erated according to the needs of the individu­
a l components. It regu lates consumption, so
that more electrical energy is not being used
than is being generated and ensures an opti­
mal state of charge for the battery .
(D Tips
-But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are l imited.
- If starting ab ility is threatened, you are
i nformed by a warn ing
c!;> page 148,
Driver notification in the instrument
cluster display.
Int ellig ent technolog y 147
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driv ing, in city traff ic and during the cold time
of year . Abundant electrical energy is re ­
quired, but only a l ittle is generated .
It is also
c ritical if the engi ne is not running and electri­
ca l components are turned on . In this in­
stance ene rgy is be ing consumed but none is
being generated.
It i s in precise ly these situations that you will
notice ene rgy management act ive ly regu lat­
ing the d istribu tion of ene rgy.
V ehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks , e lectr ica l compo­
nents a re g radually cut back or switched off.
T his reduces energy consumption and ma in­
ta ins s tart ing capability over a longer pe riod .
Take into considerat ion that when you unlock
you r vehicle, some convenience functions,
s u ch as the remo te key o r power seat adjust­
ment, may not be available. The convenience
f unct ions wi ll be available again when you
turn on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for examp le, w ith
the engine tu rned o ff, the battery is being dis ­
charged .
If starting capabi lity is jeopardized due to en­
ergy consumption , a message appears in the
driver in formation d isplay.
You have to start t he engine to charge the
battery.
With the engine running
Although electrical energy is generated when
the vehicle is being driven, the battery can be­ come discharged . This happens mostly when
little energy is being gene rated and a great
deal consumed and the battery's state of
c h arge is not opt imal.
