Replacing wh eels/ tire s
Vehicles w ith all-wheel drive must a lways
have tires of the same size. Also avoid tires
with different tread depths. For details see
page ¢
page 284, New tires and replacing
tires and wheels .
.&_ 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
tak ing extra risks.
-Although the all-wheel dr ive is very ef­
fective, always remember that braking
capacity is limited by t ire traction . You
sho uld therefore not dr ive at excessive
speeds on icy or s lippery road surfaces.
- On wet road su rfaces, be careful not to
dr ive too fast because t he front wheels
cou ld beg in to s lide on top of the wa ter
(aquaplaning). If this sho uld occ ur, you
w ill have no warning from a sudden in­
crease in engine speed as with a front­
whee l drive vehicle. A lways drive at
speeds wh ich are suited to the road con­
ditions -risk of c rash.
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.
I f a vehicle w it h a conventional energy system
i s not driven for a long pe riod of time, the bat­
tery is disch arged by idling c urrent cons umers
(e .g. immobilizer) . In ce rtain c ircumstances it
can result in there being insufficient energy
ava ilab le to start the engine .
I n tell igen t energy management in your vehi ­
cle hand les the d istribution of electrical ener ­
gy . Starting abi lity is marked ly imp roved and
the life of the battery is extended.
Int ellig ent technolog y 229
Basica lly, energy management consis ts of
batte ry diagnosi s, idling cur rent manage­
ment
and dynamic energy management.
Battery diagnosis
B attery diagnosis continuously de termines
the state of the battery . Sensors determine
batte ry voltage, battery current and battery
temperature . This determines the current
state of charge and the power of the battery.
Idling current management
Id lin g cur ren t man agement reduces energy
consumption while the vehi cle is standing.
With the ig nition switched off, it controls the
energy supply to the various electrical compo­ nents. Data from battery diagnos is is cons id­
ered.
Depend ing on the battery's state of cha rge,
individual cons umers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy manag ement
While the vehicle is being driven, dynamic en ­
ergy management distrib utes the energy ge n­
erated according to the needs of the individ u­
al components. It regulates consumption, so
that more electrical energy is not being used
than is be ing generated and ensures an opti­
mal state of charge for the battery .
(D Tips
-But even e nergy management cannot
negate the limits of physics. Consider
t hat the powe r and l ife of a bat tery are
l imited.
- If start ing ability is threatened, you are
informed by a warning ¢

Driver notification in the instrument
cluster display.

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
t he 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.
- Compare the track of your vehicle with
the distance between the guide rails of
the facility -there is a risk of damage to
the wheels and tires .
- Compare the height and width of your
vehicle with the he ight and width of the
tunnel at the fac ility. -
To prevent paint damage, do not wash
the vehicle in direct sunlight.
- T o reduce the r isk o f 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
ha rd wax .
- Never use car wash cycles that apply protective wax.
It can destroy the
matte fin ish effect .
- Do not place any stickers or magnet ic
signs on vehicle parts painted w ith
matte fin ish paint. The paint cou ld be
damaged when the stickers o r magnets
a re removed.
@ For the sake of the environment
Only wash the ve hicl e in facilities spec ially
designed for that purpose . This will red uce
the r is k of dirty water contam inated with
oil from entering the sewer system.
Cleaning and care information
When clean ing and caring for individual vehi­
cle components, refer to the follow ing tables.
The information contained there is s imply rec ­
ommendations . For quest ions or for compo- nents that are not listed, refer to an author­
ized Audi dealer or a qualified workshop. Also

For year-round driv ing, antifreeze is added at
the factory for temperatures down to:
- - 31 °F (- 35 °C) USA
- - 40 °F ( - 40 °C) Canada .
If you mus t add coolant, use a mixture of wa­
ter and coolant additive. Mixing the coolant
additive with distilled water is recommended .
A WARNING
-
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ¢
A in Working in the engine
compartment on page 257.
(D Note
-Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions. This is especially impor­
tant if you live in a region where the win­
ter is extremely cold.
If necessary, in­
crease the proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad­
ditive Gl2++ or G13 for your vehicle.
This coolant additive is available at au­
thorized Audi dealers. Other types of
antifreeze can significantly reduce cor­
rosion protection . The resulting corro­
sion can cause a loss of coolant and se­
rious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in damage not covered by your New Vehicle
Limited Warranty.
Checking and filling 265
Checking the engine coolant level
T he engine coolant level can be checked with
a quick glance.
Fig. 245 En gin e compar tment: Coolant expansion tank
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS ¢ A in Working in the engine comport­
ment on page 257 .
.,. Park your vehicle on a level surface.
.,. Turn
off the ignition .
.,. Let the engine cool down.
.,. Place a thick rag over the coolant expans ion
tank ¢
fig. 245, c> page 259, fig. 241 and
carefully twist the cap counter-clockwise
¢,&. .
.,. Read the engine coolant level in the open
coolant expansion tank. With a cold engine,
the coolant level should be between the
"min " and "max" markings. When the en­
gine is warm, the level may be slightly
above
the "max" marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration
¢ page 259 .
To obtain an accurate reading, the engine
must be switched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor .
When the coolant level is too low, the warning
light in the Auto-Check System¢
page 32 will
blink until you add coolant and the level has
been restored to normal. Even though there is
an electric coolant level sensor, we still rec­ ommend you check the coolant level from
time to time .

292 Tires and wheels
TPMS malfunction indicato r is combined with
the low tire pressure telltale . When the sys­
tem detects a malfunct ion, the te lltale will
flash for approximately one minute and then
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 t ire pressure as intended. TPMS
malfunctions may occur for a variety of rea­
sons, includ ing the installat ion of replace­
ment or alt ernate tires or wheels on the vehi­
cle that prevent the TPMS from functioning
properly. Always check the TPMS malfunct ion
tellta le after replacing one or more tires or
wheels on your vehicle to ensure that the re­ p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
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. 254 D isplay: underinflat ion wa rning
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 instr u­
ment cluster with a
[D] warning symbol and a
message ¢
fig. 254. The driver message in the
display goes out after S seconds. The driver
message can be displayed again by pressing
the
! CHECK I button . If only one tire is affect­
ed, the display will indicate its position . The tire pressure
monitoring must be reset via
MMI each time the pressures are adjusted (e.
g. when switching between partial and full
load pressure) or after changing or replacing a
tire on your vehicle¢
page 293. The TPMS in­
dicator on ly monitors the tire pressure that
you have prev iously stored . You can find the
re commended t ire pressures for your vehicle
on the label on driver's s ide B-pillar
¢page 277.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the t ire pressure in one or more tires is too
low,
- the t ire has structural damage,
- the t ire pressure was changed, wheels rotat-
ed or replaced but the TPMS was not reset
¢page 293.
Warning symbols
[D] Loss of pressure in at least one tire¢.&. .
Check the tire or tires and replace or repa ir if
necessary. The
[I] indicator light in the instru­
ment cluster also illuminates
¢page 14.
Check/correct the pressures of all four tires
and reset TPMS via MMI.
@m (T ire Pressure Mon itor ing System) Tire
pressure: System malfunction!.
If ffiim appears afte r switching the ignition on
or whi le dr iving and the
[D] indicator light in
the instrument cluster blinks for approx i­
mately one minute and then stays on, there is
a system malfunct ion .
Attempt to store the correct tire pressure
¢
page 293. If the indicator light does not
turn off or if it turns on shortly thereafter, im­
med iate ly drive your vehicle to a n author ized
Audi dealer or authorized repair facility to
have the malfunction corrected.
