- Switch the cruise control off temporarily
when dr iv ing in turning lanes, highway
exits or in construction zones.
- Please note that unconsciously "resting"
your foot on the accelerator pedal causes
cru ise contro l not to brake. This is due to
the control system being overridden by
the driver's acceleration.
- Never use the cruise control when driving
off-road or on unpaved roads. The cruise

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

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.
Page 103 of 316

-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.
