can result in there being insufficient energy
avai lab le to start the engine .
I ntell igent energy management in your vehi
cle handles the distribution of electrical ener
gy . Starting abi lity is markedly improved and
the life of the battery is extended .
Basically , energy management consists of
battery diagnosis , idling current manage
ment
and dynamic energy management.
Battery diagnosis
Battery diagnosis continuously determines
the state of the battery. Sensors determine
battery volta ge, battery current and battery
temperature. This determines the current
state of charge and the power of the battery.
Idling current management
Idling current management reduces energy
consumption while the vehicle is stand ing.
With the ignition switched off, it contro ls the
energy supply to the various e lectrica l compo
nents. Data from battery diagnosis is consid
ered.
Depending on the battery's state of charge,
individua l consumers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy management
While the vehicle is being dr iven , dynamic en
e rg y management distributes the energy gen
erated according to the needs of the individu
a l components. It regulates consumption, so
that more ele ctrical 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 energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are
limited .
- If starting ab ility is threatened, you are
i nformed by a warn ing
c> page 233,
Driver notification in the instrument
cluster display .
What you should know
The highest priority is given to maintaining
starting capability .
The battery is seve rely taxed in shor t-distance
driving, in city tra ffic and dur ing the cold time
of year . Abundant electrical energy is re
quired, but only a little is generated . It is also
critical if the engine is not running and e lectri
ca l components are turned on . In this in
stance energy is being consumed but none is
being generated.
It i s in precisely these situations that you will
notice energy management actively regulat
ing the distribution of energy.
Vehicle 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 are gradually cut back or sw itched off.
T his reduces energy consumption and main
ta ins start ing capability over a longer period .
Take into consideration that when you unlock
your vehicle , some conven ience functions ,
s uc h as the inte rior lights or the power seat
adjustment, may not be available. The con
venience functions will be available again
when you turn on the ignition and start the e ngine .
With the engine turned off
If you listen to the radio, for example, w ith
the engine turned off or use other MMI func
tions, the battery is being discharged .
If starting capability is jeopardized due to en
ergy consumption , the following warning ap
pears in the MMI display:
Please start engine, otherwise system will
switch off in 3 minutes .
The warning indicates that the system will be
turned off automatically after 3 minutes . If
you w ish to continue using the funct ions, you
have to sta rt the eng ine.

container meets industry standards (ANSI/
ASTM F852 -86).
(D Note
Never drive yo ur vehicle unt il the fuel tank
is complete ly empty. The irregular supply
of fuel can cause misfiring . Gasoline could
enter the exhaust system and damage the
catalyt ic converter.
Refuelling
F ig. 234 Righ t rear vehicle side: Opening th e fue l fill er
flap
F ig. 235 Fu el cap hooked on the opened fuel filler flap
When adding fuel, the ignition and any cellu
lar phones in the vehicle must be sw itched
off. When activating the central locking, the
fuel filler flap is automatica lly unlocked or
locked. Refuel the ve hicle w ith the ignition
turned
off.
Tak ing th e fu el cap off
• To open the fuel filler flap, press on the left
s ide of the flap¢
fig. 234 -arrow- .
• Unscrew fuel fil ler cap counter-clockwise
and hang it on the fuel fille r flap ¢
fig. 235.
• Check the label on the inside o f the f uel fill
er flap to determine if the vehicle must be
fueled with gasoline or diesel fuel.
Fuel suppl y and filli ng your fuel t ank 259
Refuelling p ro cedur e
• Insert the fuel nozz le from the gasoline
pump into the fuel fi ller neck as far as it wi ll
go .
• Select a medi um refue lling rate so that the
nozz le switches off automatically when the
tank is full.
Pu tting th e fuel cap bac k on
• After fi lling your tank, twist the fuel filler
cap clockwise as far as it wi ll go.
• Close the fue l filler flap.
T o avoid fuel spill ing or evaporating from the
fuel tank always close fuel filler cap proper ly
and completely. An improperly closed fuel fill
er cap may also cause the MIL lamp¢
page 2 7
to come on (only vehicles with gasoline en
gine).
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injur ies.
- Failure to shut the engine off wh ile refu
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fue l to spray out of filler neck or to over
f low. Fue l spray and overflowing fue l can
cause a fi re.
- Never use a cel lu lar telephone while re
fueling. The electromagnetic rad iation
can cause sparks that can ignite f uel va
pors and cause a fire.
- Never get back into your vehicle whi le re
fueling. If in exceptional circumstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge
stat ic electricity before touching the fill
er nozzle again. Static e lectricity can
cause sparks that can ignite fuel vapors re leased du ring refuel ing .
- Never smoke or have an open flame any
where in or near your veh icle when refu-
eling or filling a portab le fue l conta iner.

Selective catalytic
reduction
General information
App lies to vehicles : with diesel engine
On vehicles w ith select ive catalytic reduction,
an urea solut ion (Ad Blue ®) is injected into the
exhaust system befo re a nitrogen oxide cata
lytic converter to reduce nitrogen em iss ions.
The AdBlue is stored in a separate tank in the
veh icle. The AdBlue usage accounts for ap
p rox imately 0.5% to 1.2% of the diese l fuel
that is used. The Ad Blue tank capaci ty is ap
pr ox ima tely 6 gallons (23 liters).
You must refill the Ad Blue or have it refilled
by your authorized A udi dealer or qualified
wo rkshop as soon as the Ad Bl ue refill mes-
Fu el suppl y and filli ng your fuel t ank 261
sage appears in the instrument cluster
¢ page 262.
A WARNING
Failure to heed AdBlue refill info rmation in
the instrument cluster can prevent the ve hi cle from be ing started and dr iven. If the
vehicle cannot be driven and a n emerge ncy
a rises, pe rsonal injury can occur.
- Always have the AdBlue tank refilled well
befo re the tank runs dry .
(D Tips
- The instrument cluster d isp lay ind icates
the distance remain ing that can be driv
en ¢
page 261. If the Ad B lue tank is
completely empty, the engine will not
start again afte r the ignit ion is switched
off.
- Ad Blue is req uired by law to operate th is
veh icl e.
