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
li mited.
- If starting ability is threatened, the indi­
cator light (•) appears¢
page 17.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time
of year. Abundant e lectrica l energy is re­
quired, but only a little is generated.
It is also
crit ical if the engine is not running and electri­
cal components are turned on. In this in­
stance energy is being consumed but none is be ing generated .
It is in precisely these situations that you wi ll
notice energy management actively regulat­
ing the distribution of energy.
Vehicle stands for an e xtended period
If you do not drive your vehicle over a period
of severa l days or weeks, electrical compo­
nents are gradually cut back or switched
off.
This reduces energy consumption and main­
tains starting capab ility over a longer period.
Some of the conven ience functions may not
ope rate, such as the inter ior lights or the
power seat adjustment. The conven ience
f u nctions w ill 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 engine turned
off or use other MMI func­
tions, the battery is being discha rged .
If starting capability is jeopardized due to en­
ergy consumpt ion, the following warning ap­
pears in t he MMI display:
Please start the engine soon or the system
will be turned off.
The wa rn ing ind icates that the system will be
turned
off automatically after 3 minutes. If
you wish to continue using the functions, yo u
have to start the engine.
With the engine running
Although electrical energy is generated when
the vehicl e is being driven, the battery can be­
come discharged. This happens mostly when
little energy is being generated and a great
deal consumed and t he battery's state of
charge is not opt imal.
To bring the energy ba lance back into equili­
brium , consumers which require especially
large amounts of energy are temporari ly cut
back or switched
off. Heating systems in par­
t icular require a great deal of energy. If you
notice, for example, that the heated seats" or
the heated rear window are not heating, they
have been temporarily cut back or sw itched
off. These systems w ill be available again as
soon as the energy balance has been restored.
You will also notice that engine idle speed has
been increased slightly . This is normal and not
a cause for concern. By increasing engine idle
speed the addi tional energy requi red is gener­
ated and the batt ery is charged.

210 Trailer towing
A lways apply brakes early. When driving
downhill, shift into a lower gear to use the en­
g ine braking effect to slow the vehicle . Use of
the brakes alone can cause them to overheat
and fail.
Air su spen sion *
When driving with a trai ler, activate the trailer
mode of the air suspension. Switch the air
suspension trailer mode on when you are tow­
ing a trailer. This will limit the regulation by
the air suspens ion while driving. Select in the
MMI:
! CARI function button> (C ar)* sys te m s
control button > Vehicl e se tting s> Air s usp .:
t o wing > On .
Coolant t emperatur e
The coolant temperature gauge¢ page 11
must be observed carefully. The coolant tem­
perature can increase if you drive on long in­
clines in a low gear at high engine speeds. Re­
duce your speed immed iate ly if the LEDs in
the top pa rt of the display turn on.
For more information about indicator lights,
refer to. ¢ page 16 .
A WARNING
Anyone not properly restrained in a mov­
ing veh icle is at a much greater risk in an
accident. Never let anyone r ide in your car
who is not prope rly wearing the restraints
provided by Audi .
Trailer towing tips
Important to know
Your vehicle handles differently when tow ing
-
a trailer because of the addit ional weight and
d ifferent weight dist ribution. Safety, perform­
ance and economy w ill greatly depend on how
carefu lly you load your trailer and operate
your rig.
Before you actually tow your trailer, practice
turn ing, stopp ing and back ing up in an area
away from traffic. Keep practicing until you
have become comp letely familiar with the way your vehicle
-trailer combination behaves and
responds .
Backi ng up is diffic ult and requi res p ractice.
Backing up w ith a trailer generally req uires
steering action opposite to that when backing
up your vehicle without a trailer.
Maintai n a greater d ista nce between yo ur ve­
hicle and the one in fron t of yo u. You w ill need
more room to stop. To compensate for the
trailer, you will need a larger than normal
turning radius.
When passing, remember that you cannot ac­ ce le rate as fast as you norma lly would be­
ca use of the added load. Make sure you have
enough room to pass . After passing, allow
plenty of room for your trailer before chang­
ing lanes again.
Avoid jerky starts, sharp tu rns o r rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the extra load ¢
page 294.
Parking on a slope
Do not park on a slope with a trailer. If it can­
not be avoided, do so only after doing the fol­
lowing:
When parking:
.,. App ly the foot brake .
.,. Have someone place choc ks unde r both the
vehicle and the trailer wheels.
.,. With chocks in place, slowly release the
brakes unt il the whee l chocks absorb the
load .
.,. Turn the whee ls towards the curb.
.,. Apply the parking brake.
.,. Select the P selector lever posit ion.
When re sta rting after p ark in g :
.,. App ly the foot brake .
.,. Start the engine.

@ Tips
-The oil pressure warning display. i s
not an indicator of the oil level. Do not
rely on it. Instead , check the oil level in
your engine at regular intervals, pref­
erably each time you refuel , and always
before going on a long trip .
-If you have the impression your engine
consumes excessive amounts of oil, we r ecommend that you consult your Audi
dealer to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate measurement of oil con­
sumption requires great care and may
take some time. Your Audi dealer has in ­
structions about how to measure oil con­
sumption accurately.

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. 205 Display: underinflation warning
Fig. 206 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
ment cluster with a warning symbol
rD] and a
message
c:> fig . 205.
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad­
justed (e.g. when switching between partial
and fu ll load pressure) or after changing or re­
placing a tire on your vehicle
c:> page272 . 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
c:>page247.
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,

c:> page 272. If the indicator light
does not turn off or if it turns on shortly
thereafter, immediately drive your vehicle to
an authorized Audi dealer or authorized repair
facility to have the malfunction corrected.
_& WARNING
- If the tire pressure indicator appears in
the instrument cluster display, one or
more of your tires is significantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures. In­
flate the tire pressure to the proper pres­
sure as indicated on the vehicle's tire
pressure label<=:>
page 247 . Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must check the tire pressures regularly.
