Start-Stop-System
Descript ion
A ppl ies to vehicles: with Sta rt-Stop-System
The Start-Stop -System can help increase fuel
economy and reduce CO
2 emissions.
In the Start-Stop-mode, the eng ine shuts off
automatically when the vehicle is stopped,
such as at a traffic light. The ignition remains
sw itched on during this stop phase. The en­
gine will be automatically restarted when
needed.
The last Start-Stop-System setting (o n/off us­
ing the button
lr.;, .. I) will be restored when the
ignition is turned on. The LED in the
1r.;, .. 1 but­
ton turns on when the Start-Stop-System is
switched off manually.
Basic requirements for the Start-Stop
mode
- The driver's door is closed .
- The driver's seat belt is latched.
- The hood is closed.
- The vehicle must have been driven faster
than 2.5 mph (4 km/h) since the last stop .
- A tra iler is not hitched to the veh icle .
A WARNING
- Never turn off the engine before the ve­
hicle has come to a complete stop. The
full function of the brake booster and the
power steering is not guaranteed. You
On the road 91
must use more force to turn or brake if
necessary. Because you cannot steer and
brake as you usually would, this could
lead to crashes and ser ious injuries.
- To reduce the risk of injuries, make sure
that the Start-Stop-System is turned off
when working in the engine compart­
ment

Hybrid
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

.,. To turn on EV mode, press the 14'1 button.
The indicator light in the button will turn
on . The. indicator light a lso turns on in
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 l~ I button ¢ fig. 108 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. 107. 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.

-Offroad mode and hill descent assist must
not be turned on
c::> 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 :
- Th e ign ition is turned off.
- Th e
1.:1"1 button is pressed again.
- The high voltage battery charge level is low .
- The veh icle speed is higher than approxi -
mately 62 mph (100 km/h).
- The
S selector lever position or tiptronic
mode is selected .
- 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 combustion
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 selected, 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 elect ric 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 in 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. 107 @. 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
c::> page 98, fig. 107 @.
The energy recovery is shown in the MMI dis­
play
c::> 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 comb ustion engine
is low.
- The temperature of the catalyt ic converter is
low .
- The power output needed for the A/C sys-
t em is high.
- The vehicle speed is hig h.
- 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 mo re 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 Ma x charge.
