therefore best to avoid rough tracks and un ­
even terrain as much as possible . Also refer to
<=:> page 203.
A WARNING
Always adjust your driving to road and traf­
fic conditions. Do not let the extra safety
afforded by all-wheel dr ive tempt you into
taking extra risks.
- Although the all-wheel dr ive is very ef­
fective, a lways remember that braking
capacity is limited by t ire traction . Yo u
should therefore not dr ive at excessive
speeds on icy or slippery road su rfaces.
- On wet road su rfaces, be careful not to
dr ive too fast because t he fro nt wheels
c ou ld beg in to s lide on top of the wa ter
(aq uaplaning). If this sho uld occ ur, you
will have no warning from a sudden in ­
crease in engine speed as with a front ­
wheel drive vehicle. A lways drive at
speeds wh ich are suited to the road con­
ditions -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimi zes the
availability of electrical energy for starting the engine .
If a veh icle wit h a conventional energy system
i s not d riven for a lo ng pe riod o f time, the bat­
tery is discha rged by idling cu rrent co nsu mers
(e .g. immobilizer) . In ce rtain c ircumstances it
can result in there being insufficient ene rgy
avai lab le to start the engine .
I n tell igen t energy m anagemen t in your veh i­
cle hand les the d istribu tion of electrical ener­
gy . Starting ab ility is marked ly imp roved and
the life of the battery is extended.
B asically , energy management consists o f
battery diagnos is , idling current manage­
ment
and dynamic ene rgy man agement.
Int ellig ent technolog y 199
Battery diagnosis
Battery diagnosis continuously de termines
the state of the battery . Sensors de termine
batte ry voltage, battery current and battery
temperature . This determines the current
state of charge and the power of the battery.
Idling current management
Idling curren t management reduces energy
consumption while the vehi cle is standing.
With the ignition switched off, it controls the
energy supply to the various electrica l compo­
nents. Data from battery diagnos is is cons id­
ered .
Depending on the battery's state of charge,
i ndivid ua l cons umers are g radually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability .
Dynamic energy management
While the vehicle is being driven, dynamic en ­
ergy ma nagement distrib utes the energy ge n­
erated accord ing to the needs of the individ u­
al components . It regulates consum ption, so
that more electrical energy is not being used
than is being generated and ensures an opti­
mal state of cha rge for the battery .
(D Tips
-But even ene rgy management cannot
negate the limits of physics. Consider
t hat the powe r and life of a battery are
limited .
- If start ing ability is threatened , the indi­
cator light (•) appears
c::> page 17 .
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 on ly a little is generated . It is also ..,. •

A WARNING
-Only wash the vehicle when the ignition
is off and follow the instructions from
the car wash operator to reduce the risk of accidents .
- To reduce the r isk of cuts, protect your­
self from sharp metal components when
wash ing the underbody or the inside of
the wheel housings.
- After washing the vehicle, the braking ef­
fec t may be delayed due to mo isture on
the brake rotors or ice in the winter. The
brakes must be dried first with a few
careful brake applications.
Q) Note
- If you wash t he vehicle in an automatic
car wash, yo u must fold the exterior m ir­
rors in to reduce the r is k of damage to
the mirrors. Power folding exterior mir­
rors* must only be folded in and out us­
ing the power folding function.
- To prevent paint damage, do not wash
the vehicle in direct sunlight . -
To reduce the risk of damage to the sur­
face, do not use insect removing spong­
es, kitchen sponges or similar items.
- Matte finish painted vehicle compo­
nents:
- To reduce the risk of damage to the surface, do not use polishing agents or hard wax.
- Never use car wash cycles that apply protective wax.
It can destroy the
matte fi nish effect.
- Do not place any stickers or magnet ic
signs on vehicle parts painted w ith
matte fi nish paint. The paint cou ld be
damaged when the stickers o r magnets
are removed.
@ For the sake of the environment
Only wash the vehi cle in facilities spec ial ly
designed for that purpose . This will red uce
the risk of dirty water contam inated with
oil from entering the sewer system.

232 Check ing and filling
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig . 191 Eng ine compartment: cover on the coolant
expa nsion tank
Before you check anything in the engine com­
partment,
a lwa ys re ad and h eed a ll WA RN­
INGS o .A in Working in the engine compart­
ment on page 224 .
., Park your vehicle on a level surface.
., Switch
off the ignit io n.
., Read the eng ine coolant level from the cool ­
ant expans ion tank
o fig . 191, o page 226,
fig. 188. With a cold eng ine, the coolant
level should be between the "min" and
"max" markings. When the engine is warm,
the leve l may be slightly above the "max"
marking.
The location of the coolant exp ans ion tank
can be seen in the engine compartment illus­
tration
o page 226.
To obtain an accurate read ing, the engine
must be switched
off.
The expans ion tank in your vehicle is equipped
with an e lectric coolant level sensor .
When the coolant level is too low, the warning
light in the Auto-Check System
o page 17 will
illum inate unt il you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level senso r, we
still recommend you check the coolant leve l
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cool ing
system. In the event of coolant loss, the cool- ing system shou
ld be inspected immediately
by your authorized Audi dea ler . It is not
enough mere ly to add coolant .
In a
sea le d system, losses can occur on ly if
the boiling point of the coo lant is exceeded as
a resu lt of overheating.
A WARNING
-The cooling system is under pressure and
can get very hot . Red uce the risk of scald­
i ng from hot coolant by fo llow ing these
steps.
- Turn
off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping flu id and steam by covering the
cap with a large, th ick rag .
- Turn the cap slowly and very carefully in
a counter-clockwise d irect ion while ap­
plying light, downward pressure on the
top of the cap .
- To avo id being burned, do not sp ill anti­
freeze or coolant on the exhaust system
or hot engine parts . Under certa in cond i­
tions, the ethylene glycol in engine cool­
ant can catch fire.
0 Note
Do not add any type of radiator leak seal­
ant to your veh icle's engine coolant . Add­
i ng radiator repa ir fluid may adverse ly af­
fe ct the funct io n and performance of your
cooling system and could result in damage not covered by your New Vehicle Limited
Warranty.
Adding coolant
Be very careful when adding engine coolant .

remain continuously illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low tire pressure as intended . TPMS
malfunctions may occur for a variety of rea­
sons, including the installation of replace­
ment or alternate tires or wheels on the vehi­
cle that prevent the TPMS from functioning
properly . Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the re­
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Appl ies to vehicles: with tire pressur e monitoring sys te m
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
Fig. 200 Display : underinflation warning
Fig. 201 Display: System malfunction
Using the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum­
ference and vibration characteristics of the in­
dividual tires. If the pressure decreases in one
or more tires, this is indicated in the instru-
Tires and wheels 259
ment cluster with a warning symbol [I] and a
message
c::, fig. 200.
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad­
justed (e.g. when switching between partial
and full load pressure) or after changing or re­
placing a tire on your vehicle
c::, page 260. The
TPMS indicator only monitors the tire pres­
sure that you have previously stored. You can
find the recommended tire pressures for your
vehicle on the label on driver's side 8-pillar
~page 244.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the tire pressure in one or more tires is too
low,
- the tire has structural damage,
- the tire pressure was changed, wheels rotat-
ed or replaced but the TPMS was not reset
c::, page 260 .
