Hybrid drive
Introduction
Applies to vehicles: with hybri d dr ive
General information
The hybrid drive is a combined drive concept
that automat ically switches between combus­
tion engine and e lectric dr ive types or com­
b ines them.
All work on h igh voltage systems is intended
only for high voltage technicians and may only
be performed by authorized service facilities
in accordance with Audi regulations.
The high voltage system is composed of the
following h igh voltage components : the high
voltage battery, the power electronics, the
e lectric motor, the high voltage A/C compres­
sor and the orange high voltage wiring.
High voltage battery
The high voltage battery is located in the lug­
gage compartment underneath the cargo
floor. You do not need to perform any mainte­
nance work on the high voltage battery . Addi ­
tional information about the high voltage bat­
tery can be found under
r=> page 105.
The high voltage battery serv ice plug is a lso
found underneath an orange cover under the
cargo floor. The service plug is provided on ly
for use by service personnel 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
voltage component can result in a fatal
electric shock. The components in the high
voltage system are marked with a warn ing
label which warns against the high volt­
age.
- Never perform work on orange high volt­
age cables or on high voltage compo­
nents . On ly authorized repair facilities
Hybr id 97
that are certified may perform work on
the high voltage system.
- Never open or remove the service plug
cover in the center of the cargo floor.
- Never damage, alter or remove the or­
ange high voltage cable or disconnect it
from the high voltage system.
- Audi regulations must be followed dur­
ing all work performed on the high volt­
age system and high voltage compo­ nents.
A WARNING
While in electric drive mode, the vehicle
produces considerably less idling, driving
and operat ing noise than when the com­
bustion engine is running. This may make
it difficult or impossible for others such as
pedestrians and children to hear and no­
tice the vehicle when it is in electrical drive
mode. This can lead to co llisions and inju­
ries, for examp le in low traffic areas, when
maneuvering or when driving in reverse.
A WARNING
-
-
Never leave the vehicle unattended while
in the drive ready mode. The vehicle could
begin moving if the accelerator pedal is
pressed, even if the combustion engine is
switched off . This may cause collisions and
severe or fata l injuries. When the vehicle
enters drive ready mode, the status mes­
sage
ybr I P cl, appears briefly in the in­
strument cluster disp lay and the needle in
the power meter points to
READY
r=> page98 .
-When exiting the vehicle, make sure the
selector lever is in the P position, the ig­
nition is switched off and the hybrid sys­
tem is deactivated .
(D Note
-The high voltage system can be damaged
if the vehicle underbody comes into con­
tact with the ground . Immediate ly drive
your vehicle to an authorized repair fa­ cility and have it inspected.

98 Hybrid -Do not transport fluids in open contain­
ers in the luggage compartment. Spilled
fluids can seep underneath the cargo
floor. This can damage the high voltage
system.
Starting the vehicle
App lies to vehicles: with hybrid drive
The vehicle is started and turned off either
with the ignition key~
page 83 or with the
I START ENGIN E STOP ! button* ~ page 86 in
the same way as a conventional vehicle .
When starting the vehicle, the needles in the instrument cluster move upward briefly .
When the vehicle enters drive ready mode,
the status message
hybrid ready appears
briefly in the instrument cluster display and
the needle in the power meter points to

the instrument cluster display.
The functions and operating modes described
be low are se lected automatica lly by the vehi­
cle control system, depending on the vehicle
operat ing status. This ensures that the vehicle
is always in the correct operating mode. One
exception is the enhanced electric driving
mode (EV mode), which is activated by the
driver
¢pag e 100.
Driving with the combustion engine
The vehicle is powered by the combustion en­
gine. The h igh voltage battery is charged si­
multaneously, if needed.
Full acceleration (boost)
In full acceleration, the vehicle is powered by
both the combustion engine and the electric
motor . This operating mode is called
Boost
and is on ly available for a short amount of
time because it uses so much energy. Availa ­
bility depends on the high voltage battery
charge level.
The boost operating mode is activated by
pressing the accelerator pedal all the way
down.
Electric driving
The vehicle can be driven completely electri­
ca lly depending on the high vo ltage battery
charge level and the driving resistance. The
combust ion eng ine turns off at that t ime.
The combustion engine starts when accelerat ­
ing or when the high voltage battery charge
level drops be low a certain threshold. The ve­
hicle resumes e lectric driving once the accel­
eration and the high voltage battery charge
level permit.
Enhanced electric driving mode (EV
mode)
Pressing the 1~ 1 button ¢ fig. 109 can extend
the usual limits on electric driving so that you
can always drive in electric mode, if the condi­
t ion of the e lectr ica l system permits . The op­
erating mode is then set to maximum electric
drive @,@ ¢
page 98, fig. 108. It can be
driven complete ly elec trically for up to 1.8
miles (3 km) at a constant 37 mph (60 km/h) .
T he following conditions must be met to act i­
vate the enhanced e lectr ic drive:
- The high voltage battery must be suffic ient­
ly charged.
- The temperature of the 12 volt batter ies
and the hig h voltage battery must be suffi­
cient.
- The vehicle speed must not be higher than
62 mph (100 km/h).
- The transmission must not be in tiptronic
mode.

-ESC offroad mode and hill descent assist
must not be turned on¢
page 198 .
The combust ion eng ine tu rns on and inter­
rupts
the enhanced electric d rive mode when
the vehicle is accelerated. The gray indicator
light
l!I also turns on in the disp lay. The en­
hanced electric drive mode resumes automati ­
cally once acceleration stops.
The enhanced e lectric drive mode is
deactivat­
ed if at least one of the following conditions is
met :
- The ign ition is turned
off.
- Th e 1.:1"1 button is pressed again.
- The high voltage battery charge level is low .
- The vehicle speed is higher than approxi -
mately 62 mph (100 km/h).
- The S selector lever position or tiptronic
mode is selected .
- ESC offroad mode or hill descent assist is
switched on .
T he
ld" I button must be pressed to reactivate
it .
Start-Stop function
The combustion engine is operated on ly as
needed. Generally, the combustion engine
turns
off when the vehicle is stationary and
the high voltage battery powers the electrical
vehicle systems.
The purpose of automatica lly shutting the
combustion engine
off in hybrid drive mode is
to save fuel. All of the important veh icle sys­
tems, such as steering, brakes and the A/C
system, cont inue to remain active. In some
cases , systems may require the combustion
engine to cont inue running when the vehicle
is stationary. When dr iv ing in congested traf­
fic for long per iods of time, the comb ustion
engine w ill cycle on when the vehicle is sta­
tionary to keep the high voltage battery
charged.
Gliding
I f the gas pedal is not pressed and the D posi­
tion is selec ted, the combustion engine re-
Hybrid 101
mains turned off up to speeds of approxi ­
mately 99 mph (160 km/h). Driving conserva­
tive ly like this can reduce fuel consumption.
Energy recovery (recuperation)
When braking, the electric motor will act as a
generator creating e lectric energy that is then
stored in the high voltage battery. This also
occurs when the ve hicle is coasting or driving
downhi ll. The combustion engine is automati­
cally turned
off i n this case.
The vehicle is braked with the electric motor
by applying ear ly and even pressure to the
brakes and using short pedal movements
¢
page 98, fig. 108 @. By doing this, a large
amount of the kinetic energy is recovered and
may be stored as electric energy in the high
voltage battery . During heavy braking, the
convent ional brakes are also act ivated
¢ page 98, fig. 108 @.
The energy recovery is shown in the MMI dis­
play ¢
page 104.
Automatic start of the combustion engine
Various operating conditions cause the com­
bust ion engine to start automat ically :
- The high voltage battery charge leve l is low.
- The temperature of the combustion engine
is low.
- The temperature of the catalytic converter is
low .
- The power output needed for the A/C sys-
t em is high.
- The vehicle speed is high.
- The vehicle acceleration is high.
- The inclin e is steep.
- High charge level for the high voltage bat-
tery when coasting. In th is case, the h igh
voltage battery cannot absorb any more en ­
ergy and so the electric motor cannot slow
down the veh icle. The combustion engine
tu rns on (engine brake). In this situation the
h igh voltage battery will show a Max charge.

pa ir set.
Charging the batteries
Applies to vehicles: with hybrid drive
The vehicle is equipped with two 12 volt bat ­
ter ies and a h igh voltage battery.
If the
12 volt batter ies are dead, they may be
charged with a charger or the vehicle may be
jump started with assistance from another ve­
hicle in the same way as a conventional vehi­
cle .
The same applies to the high voltage battery
if it is d ischarged . However, in this case, the
charg ing process is accompanied w ith mes­
sages in the inst rument cluste r display. The
i gnit ion m ust be switched on and all unneces­
sary electric components m ust be turned off.
The connections in the engine compartment
are used for both charging and jump starting

manual
This message appears if the high voltage bat­
tery charge level is too low. The vehicle can no
l onge r be started with its own power. The
high voltage battery must be charged with a
charger or the vehicle must be jump started
with the aid of another vehicle.
Afte r the connecting the cha rger or jumper ca­
b les, the ignition must be turned off for ap­
proximately two minutes and then turned on
again. After no more than one m inute, one of

with assistance from another vehicle.
If the 12 vo lt batteries are dead, the -
indicator light turns on. The charging proce­
dure takes longer in this case because the
12
volt batteries are charged first. The procedure
goes faster with the ignition switched off.

This message appears if the charging proce­
dure was successfu l. The vehicle may be start­
ed again.
Battery could not be charged enough to
start vehicle.
T his message appears if the charging proce­
dure was not successful or it was interrupted.
This may happen if the charger or the battery
in the veh icle that is assist ing is too weak.
If
the vehicle cannot be started, see an author­
ized repa ir facility for assistance .
(D Tips
- The charger should deliver a current of at
least
30 A. Otherwise charging the high
voltage battery will take considerably longer. A current between
50 A and 70 A
is ideal.
- The ve hicle that is assist ing should be
somewhat within the same vehicle class
when jump starting a vehicle. A smaller
vehicle's battery may be drained.
- After approximately
30 minutes, the
c harging procedure ends because the ig­
nition is automatically turned off.
If you
would like to continue to charge the bat­
tery, turn the ignition on again.
