Hybrid drive
Introduction
App lies to veh icles: w ith hybr id drive
Gener al inf orm ation
The hybr id drive is a combined drive concept that
automatically switches between combustion en
g ine and electr ic drive types or combines them.
All work on h igh voltage systems is intended only
for h igh voltage technicians and may only be per
formed by authorized service facilities in accord
ance w ith Aud i regulations.
The high voltage system is composed of the fol lowing h igh voltage components: the h igh volt
age battery, the power electronics, the e lectr ic
motor, the h igh voltage A/C compressor and the
orange h igh vo ltage w iring.
High volta ge battery
The high voltage battery is located in the luggage
compartment underneath the cargo floor . You do
not need to perform any maintenance work on
the high voltage battery. Additional information
about the h igh vo ltage battery can be found un
der
r::!v page 105 .
The high voltage battery service plug is a lso
found underneath an orange cover under the ca r
go floo r. T he service plug is provided on ly for use
by service personne l and must not be removed by
others who are not trained to use it .
A WARNING
The voltage in the high voltage system is life
threatening. Touching a damaged high vo lt
age component can result in a fatal electric
shock. The components in the high voltage
system are marked w ith a warning label wh ich
warns against the h igh voltage.
- Never perform work on orange h igh voltage
cables or on high voltage components. Only
authorized repair facilities that are certified
may perform wo rk on the high voltage sys
tem.
98
- Never open or remove the service plug cover
in the center of the cargo floor.
- Never damage, alter o r remove the orange
high voltage cable or disconnect it from the
high voltage system.
- Aud i regu lations must be followed during
all work performed on the high voltage sys
tem and high voltage components.
A WARNING
While in electric dr ive mode, the veh icle pro
duces considerab ly less id ling, driving and op
erat ing no ise than when the combustion en
g ine is running. This may make it difficult or
impossible fo r othe rs such as pedes trians and
chi ld ren to hear and notice the veh icle when it
is in electrical drive mode . This can lead to
collisions and inj uries, for example in low traf
fic areas, when maneuvering or when driving
in reverse.
A WARNING
Never leave the vehicle unattended whi le in
the drive ready mode. The vehicle could begin moving if the accelerator peda l is pressed,
even if the combustion engine is switched off .
This may cause collisions and severe or fatal injuries. When the vehicle enters dr ive ready
mode, the status message
h• .,rid ii J ap
pears br iefly in the instrumen t cluster display
and the needle in the powe r meter points to
READ Y ¢ page 99.
-When exi ting the vehicle, make sure these
lecto r lever is i n the P position, the ignition
is switched off and the hybrid system is de
activated.
(D Note
- T he h igh voltage system can be damaged if
the vehicle underbody comes into contact
with the ground. Immediate ly drive your ve
hicle to an authorized repair facility and
have it inspected.
- Do not transport fluids in open containers in
the luggage compartment. Spill ed fluids
can seep underneath the cargo floor. This
can damage the high voltage system.

Starting the vehicle
Applies to vehicles: with hybrid drive
The vehicle is started and turned off either w ith
the ign ition key
q page 84 or with the
IS TAR T ENGINE STOP I button* ¢page 87 in the
same way as a conventional vehicle .
When starting the vehicle, the need les in the in
strument cluster
move upward br iefly. When the
vehicle enters d rive ready mode, the status mes
sage
hybrid ready appears briefly in the instru
ment cluster display and the needl e in the power
meter points to READY
q page 99.
Depending on the operation mode of the hybr id
system, there are two possib le drive ready modes
after the vehicle has been started:

Hybrid functions and operating modes
Appl ies to vehicles: with hybri d drive
Fig. 111 Center console: av bu tton
.,. To turn on EV mode, press the l.,,;v l button. The
indicator light in the button will turn on. The
• indicator light also turns on in the instru
ment cluster display.
The functions and operating modes described be
low are selected automatically by the veh icle con
trol system, depending on the vehicle operating
status. This ensures that the vehicle is always in
the correct operating mode. One exception is the
enhanced elect ric driving mode
(E V mode), which
is activated by the driver ¢
page 101.
Driving with the combustion engine
The vehicle is powered by the combustion engine.
The high voltage battery is charged simultane
ously, if needed.
Full acceleration (boost)
In full acceleration, the vehicle is powered by
both the combustion eng ine and the electric mo
tor . This operating mode is called
Boost and is
only available for a short amount of time because
i t uses so much energy. Availability depends on
the high voltage battery charge level.
The boost operating mode is activated by press in g the accelerator peda l all the way down.
Electric driving
The vehicle can be driven completely electrically
depending on the high voltage battery charge
level and the driving res istance . The combustion
engine turns off at that t ime .
Hybrid
The combustion engine starts when accelerating
or when the high voltage battery charge level drops below a certain thresho ld. The vehicle re
sumes electric driving once the acceleration and
the high voltage battery charge level permit .
Enhanced electric driving mode (EV mode)
Pressing the 1~· 1 button r::!> fig. 111 can extend the
usual limits on e lectric driving so that you can a l
ways drive in electric mode, if the condition of
the electrical system permits. The operating
mode is then set to maximum electric drive @,
@ <:!> page 99, fig . 110. It can be driven com
pletely electrically for up to 1.8 miles (3 km) at a
constant
37 mph (60 km/h).
The following conditions must be met to activate
the enhanced electric drive:
- The high voltage battery must be sufficiently
charged.
- The temperature of the
12 volt batteries and
the high voltage battery must be sufficient.
- The vehicle speed must not be higher than
62 mph (100 km/h).
- The transmission must not be in tiptronic
mode.
- Offroad mode and hill descent assist must not
be turned on
r::!;>page 192.
T he combustion engine turns on and interrupt s
the enhanced ele ctric drive mode when the vehi
cle is acce lerated. The gray ind icator light
I§ a l
so turns on in the display. The enhanced electric
drive mode resumes automatica lly once accelera
tion stops.
The enhanced electric drive mode is
deactivated
if at least one of the following conditions is met :
- The ignition is turned off.
- The
l~ ·I button is pressed aga in.
- The high voltage battery charge level is low .
- The vehicle speed is higher than approximately
62 mph (100 km/h) .
- The
S selector lever position or tiptronic mode
is selected.
- Offroad mode or hill descent assist is switched
on .
The
l "'-'' I button must be pressed to reactivate it. 1iJ11-

Hybrid
St art-Stop function
The combust ion engine is operated only as need
ed . Genera lly, the combustion engine turns
off
when the vehicle is stationary and the high volt
age battery powers the electrical vehicle sys
tems .
The purpose o f automatica lly shutting the com
bustion engine
off in hybrid drive mode is to save
fue l. All of the important vehicle systems, such
as steering, brakes and the A/C system, contin ue
to remain active. In some cases, systems may re
qu ire the combustion engine to continue running
when the vehicle is stationary. When driv ing in
congested traffic for long periods of t i me, the
combustion engine will cycle on when the veh icle
is stationa ry to keep the h igh voltage battery
charged .
Gliding
If the gas pedal is not pressed and the D position
is selected, the combustion engine rema ins
turned
off up to speeds of approximate ly 99 mph
(160 km/h). Dr iving conse rvative ly like this can
r educe fue l consumpt ion.
Energy recovery (recup eration )
When braking, the e lectr ic motor will act as a
generator creating electric energy that is then
s to red in the h igh voltage batte ry. This also oc
curs when the ve hicle is coas ting or dr iv ing down
hi ll. The combust ion engine is automatically
turned
off in t his case.

The vehicle is braked with the electric motor by
applying early and even press ure to t he brakes
and us ing short pedal movements¢
page 99,
fig. 110@. By do ing th is, a large amount of the
k inet ic energy is recovered and may be stored as
electric energy in the high voltage batte ry. Dur
i ng heavy braking, the convent ional brakes are al
so act ivated
¢ page 99, fig . 110 @.
The energy recovery is shown in the MMI display
¢page 105 .
Automatic start of the combu stion engine
Various operating conditions cause the combus
tion eng ine to start a utomatica lly :
- T he high vo ltage battery charge leve l is low.
- T he temperature of the combustion engi ne is
low.
- Th e temperature of the cataly tic converte r is
low.
- T he power output needed for the A/C system is
high.
- T he veh icle speed is high .
- The vehicle acceleration is h igh .
- The incline is steep.
- High charge level for the high voltage battery
when coasting. In this case, the hig h voltage
battery cannot absorb any more ene rgy and so
the electric motor cannot s low down the veh i
cle. The combustion engine tur ns on (eng ine
brake) . In this situation the high voltage bat
tery will show a Max cha rge.
Vehicle behavior
In the D posit io n, the hybrid system adapts
to the driving s ituat ion by automatically
sw itch ing between the combust io n engine
a nd e lectr ic dr ive types or by combini ng
them.

Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 119 Detect ion range
What can adaptive cruise control do?
The adaptive cruise control works in conjunction
with a radar sensor installed in the front of the
vehi cle
¢ page 107, fig. 116, which is subject to
designated system limits¢
page 109 . Stationary
objects are disregarded.
On open roads w ith no traff ic, adaptive cruise
control wo rks like a reg ular cruise control system.
The stored speed is maintained . When approach
ing a moving vehicle detected up ahead, the
adapt ive cruise control system automatically
slows down to match that vehicle's speed and
then maintains the distance that the driver previ
ously stored. As soon as the system does not de
tect a vehicle up ahead, adaptive cruise control
accelerates back up to the stored speed .
Which functions can be controlled?
When you switch adaptive cruise contro l on, you
can set the current speed as the "contro l speed"
¢ page 109, Switching on and off.
When driving , you can stop cruise control
¢
page 111 or change the speed ¢ page 110 at
any time.
