" N .... 0 0 <..:l ' The energy management system Is made up of
battery diagno sis , idling current management ,
and dynamic energy management.
Battery diagnosis
The batte ry diagnosis determines the vehicle bat ­
tery charge level. The sensors detect the battery,
the battery current, and the battery temperature.
The current charge leve l and the performance of
the vehicle battery are determined based on this.
Idling current management
The idl ing current management decreases the
energy used whi le pa rked . With the engine
switched off, it manages the energy distribution
to the different electrical components . Data from
the battery diagnosis is taken into account for
this.
Depending on the vehicle battery charge level,
e lectrical equipment is switched off one item af­
ter the other to prevent the vehicle battery from
draining and to maintain the starting ability.
Dynamic energy management
While driving, dynamic energy management dis ­
tributes the appropriate amount of energy to the
e lectrical equipment. It controls the battery
charge level so that the amount of energy is not
greater than the amount being generated in or­
der to mainta in an optimal veh icle battery charge
level.
(D Tips
- Energy management cannot overcome the
laws of physics . Note that the charge level
and length of the vehicle battery life are
limited.
- When the start ing ability is endangered, the
(•) indicator light turns on
~ page 14.
What you should know
Maintaining the starting ability is the highest
priority.
A lot of stress is placed on the vehicle battery
when dr iving short distances, during c ity dr iving,
and at cold times of the year . A lot of energy is
Intelligent Technology
u sed but little is generated. It is also critical
when the engine is not running but electrical
equipment is switched on. In this case, energy is
used but none is generated.
In situations like this, energy management wi ll
active ly regulate the distribution of energy .
Long periods without use
If you do not drive your vehicle for severa l days or
weeks, electrical equ ipment is gradually scaled
back or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods of time . Some convenience functions,
s u ch as interior lighting or power seat ad just­
ment, may not be ava ilable under certain circum­
stances. These conven ience functions will be
available again once you switch the ignition on
and start the engine.
With the engine switched off
The vehicle battery will dra in if you use Infotain ­
ment functions such as listening to the radio
whi le the engine is switched off .
T he vehicle's ability to start may be impaired by
the energy use, a message will appear in the In­
fotainment system display.
The message indicates that the system wi ll
switch off automatically soon. If you would like
to continue using the functions, you must start
the engine.
With the engine running
Although e lectr ica l ene rgy is generated while
driving , the vehicle battery can drain. This can
happen if litt le energy is generated but much is
used, and the charge level of the vehicle battery
is not optimal.
To restore the balance of energy, components
that require large amounts of energy are tempo­ rarily scaled back or sw itched off. Heat ing sys­
tems in particular requ ire a great deal of energy.
If you notice, for example, that the seat heating*
or rear window defogger is not work ing, then it
has been tempora rily reduced or sw itched off.
Th ese systems are available again as soon as the
energy supply has been restored. .,.

Checking and Filling
-A worn or damaged nozzle or a nozz le that
is too sma ll may not be ab le to open the
diesel misfueling guard . If this is the case,
try turning the noz zle before inserting it in
the fuel filler neck, use a different fuel p ump, or see an authorized Audi dealer or
aut horized Aud i Serv ice Facility for ass is­
ta nce.
- The misfueling guard does not open when adding fue l from a fue l conta iner . You can
bypass it by adding the diese l fuel s low ly.

Selective catalytic
reduction (AdBlue/DEF)
General information
Appl ies to: vehicles with selective catalytic reduct ion
In vehicles with selective catalyt ic reduction, a
u rea solution (AdBlue/DEF) is injected into the
exhaust system before a nitrogen oxide catalytic
conve rter to reduce nitrogen em issions . The urea
solution is known as Ad Blue or D EF (Diesel Ex­
haust Fluid) . Ad Blue is used in the follow ing .
The Ad Blue is carried in a separate tank in the ve­ hicle. The AdBlue usage acco unts for approxi ­
mately 0 .5% to 2 .5% of the diese l fuel that is
u sed .
When a message about refilling the AdBlue ap­ pears in the instrument cl uster display, you must
ref ill the Ad B lue yourself or have it refilled by an

Catalytic converter
Applies to: vehicles with gasoline engine
It is very important that your emission control
system (cataly tic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner.
.,. Always use lead-free gasoline c:> page 190 , Fuel
supply.
.,. Never run the tank down all the way to empty .
.,. Never put too much motor o il in your engine
c:> page 203, Adding engine oil.
.,. Never try to push- or tow-start your vehicle.
The catalytic co nverter is an efficient "clean -up"
device built into the exhaust system of the ve hi­
cle. The catalyt ic converter b urns many of the
po llutants in the exhaust gas before they are re­
leased into the atmosphere.
The exclusive use of un leaded fuel is cr itically im­
portant for the life of the catalytic converte r and
prope r funct ion ing of the eng ine .
_&. WARNING
The tempera ture of t he exhaus t sys tem is
h igh, bot h when driv ing and a fter stopping
the engine .
- Never tou ch the exhaust tail pipes once they
have become hot. This cou ld resu lt in burns.
- Do not park or operate the vehicle in ar eas
where the hot exhaus t sys tem may come in
contact with dry grass, b rush, fuel spill or
other material which can ca use a fire.
- Do not app ly additiona l undercoating or
r u stp roofing on or near the exhaust mani­
fold, exha ust pipes, cata lytic converter or
heat shields . D uring driving, the substance
used for undercoat ing could overheat and
cause a fire.
CD Note
- Be aware that just one tank fi lling with
leaded fuel w ill already seriously degrade
the performance of the catalytic converter .
- Do not exceed the correct engine oil leve l

Tire pressure monitoring system
Applies to: vehicles with Tire Pressure Monitoring System in­

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. 192 Instrument clus ter : indicator ligh t w ith message
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread circumfer­
ence and vib ration characteristics of the individu­
al tires.
If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
RE and a message.
If only one tire is affected, the location of that
tire will be indicated.
The tire pressures must be stored in the Infotain ­
ment system again each time the pressures
change (switching between partial and full load pressure) or after changing or replacing a tire on
your vehicle ¢
page 230 . The tire pressure moni ­
toring system only monitors the tire pressure you have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
¢page 220, fig.191 .
Tire tread circumference and v ibration character­
istics can change and cause a tire pressure warn­
ing if:
- the tire pressure in one or more tires is too low.
- the tire has structural damage.
- the tire was replaced or the tire pressure was
changed and it was not stored

_& WARNING ,..___
- If the tire pressure indicator appears in the
d isplay, reduce your speed immediately and
avoid any hard steering or braking maneu­
vers. Stop as soon as possible and check the
tires and their pressure.
- The driver is responsible for maintaining the
correct tire pressure. You must check the

- Under certain conditions (such as a sporty
driving style, winter conditions or unpaved roads), the tire pressure monitoring system
indicator may be delayed .
@ Tips
-The tire pressure monitoring system can al­
