All wheel drive (quattro)
A ppl ies to: ve hicles wit h all wheel drive
In oil wheel drive, oil four wheels ore powered.
General info rmation
I n all wheel drive, t he driving power is divided be
tween all four wheels . This happens automatical
ly depending on your driving behavior as well as
the current road conditions. Also see
¢ page 92.
The a ll wheel d rive concept is designed for h igh
engine powe r. Your vehicle is exceptionally pow
erful and has excellent driving characteristics both under norma l driving conditions and on
snow and ice. Always read and fo llow safety pre
cautions ¢.&. .
Winter t ires
By using all wheel drive, yo ur vehicle has good
forward motion with standard tires in w inter con
ditions. However, we recommend using winter or
all season tires on
all four whee ls in the winter,
because this will improve the
broking effect.
Snow cha in s
If there are snow chain laws, snow chains must
a lso be used on vehicles with a ll wheel drive
¢ page 186, Snow chains.
Replacing t ires
F or vehicles w ith all wheel dr ive, only wheels w ith
the same ro lling circumference shou ld be used .
Avoid using tires with different tread depths
¢ page 178, New tires or wheels .
A WARNING
-Also, in vehicles with a ll wheel drive, adapt
your dr iv ing style to the current road and
traff ic conditions. Do not let the increased
safety provided tempt you into tak ing risks,
because th is increases the r is k of an acci
dent.
- The braking ability of your veh icle is limited
to the tract ion of the wheels . In this way, it
is not diffe rent from a two whee l dr ive vehi
cl e. Do not be tempted to accelerate to a
high speed when the road is slippe ry, be
cause this increases the risk of an accident .
Intellig ent Technology
- Note that on wet streets, the front wheels
can "hydrop lane" if dr iv ing at speeds that
are too high . Un like front wheel drive
veh icles, the engine does not rev higher sud
denly when the vehicle begins hydroplan ing .
For this reason, adapt yo ur speed to the
road conditions to red uce the risk of an acci
dent.
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a vehicle with a conventiona l energy sys
tem is not driven for a long time , the vehicle bat
tery is drained by equipment (for example, the
immobilizer). In certa in circumstances, there
could may not be enough energy to start the en
gine.
Yo ur vehicle is equipped with an intel ligent ener
gy management system for distributing electrici
ty . Th is sign ificantly improves the start ing ability
and increases the vehicle battery life .
The energy management system Is made up of
battery diagnosis , idling current manag em en t,
and dynamic energy manag ement .
Battery diagn osis
The battery diagnosis determines the vehicle bat
tery charge level. The sensors determine the bat
tery voltage, the battery current, and the battery
temperature. The current charge level and the
performance of the vehicle battery a re deter
mined based on this.
Idling current management
The idling current management decreases the energy used while parked. With the engine
switched off, it manages the energy dis tribution
to the d ifferent e lectr ica l components. Data from
the battery d iagnosis is taken into account for
t hi s.
97

Intelligent Technology
Depending on the vehicle battery charge level,
electrical 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 manag ement
W hile driving, dynamic energy management d is
trib utes 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 be ing generated in or
der to mainta in a n optima l vehicle battery charge
level.
(D Tips
- Ene rgy management cannot ove rcome the
l aws of physics . Note that the charge level
and length of the vehicle battery life a re
l imi ted.
- When the starting ability is endangered, the
(•) indicator light turns on
~ page 13 .
What you should know
Maintaining the starting ability is the highest
priority.
A lot of stress is placed on the vehicle battery
when dr iv ing short d ista nces, dur ing c ity dr iving,
and at cold times of the year . A lot of energy is
used but little is ge nerated.
It is a lso critical
when the engine is not runn ing but e lectr ica l
eq uipment is switc hed o n. In this case, energy is
used bu t none is ge ne ra te d.
In s ituations like this, energy manageme nt will
actively regu late the d istribution of ene rgy .
Long periods without use
I f yo u do not drive your vehicle for seve ral days or
weeks, electrical equipment is gradually scaled
back or switched off . This red uces energy use and
ensu res the veh icle w ill be able to star t afte r long
pe riods of time . Some convenience functions ,
such as inte rior lighting or powe r seat adjust
men t, may not be available unde r certa in ci rcum
s tances. These co nvenience functions will be
ava ilab le again once you switch the ign ition on
and start the engine .
98
With the engine switched off
The vehicle b attery wi ll dr ain if you use Info tain
ment func tions such as lis teni ng to the radio
while the engine is switched off.
The veh icle's abili ty to s ta rt may be impa ired by
the e nergy use, a message will appe ar i n t he I n
fota inment system display.
The message indicates that the system wi ll
swi tch off autom atically soon .
If you would lik e
to co ntin ue usi ng the func tio ns , you mus t start
t h e engine.
With the engine running
Althoug h electrica l energy is gene rated w hile
driv ing, the veh icle ba tte ry can dra in. This can
happe n if li tt le ene rgy i s generate d but much is
u sed, and the ch arge level of the vehi cle b attery
i s not optimal.
To resto re t he ba lan ce of energy, co mponents
t h at req uire large amo unts of energy a re tempo
ra rily sc aled b ack or sw itche d off. Heat ing sys
tems in partic ular re quire a great deal of energy .
If you notice, for example, that the seat heating*
or r ear window defogger is not work ing, then it
has been tempora rily reduced or switched off.
These systems are avai lab le aga in as soon as t he
energy supply has bee n restored .
In ad dition, yo u may notice that the idle speed
has slightly increased. That is normal and no
cause for concern. By increasing the idling speed,
the addit ional required energy will be ge nerated
and the veh icle battery w ill be charged .
