Introduction
Applies to: vehicles with hybrid drive
Gener al inform ation
The hybr id drive is a combined drive concept that
automatically switches between combustion en­
g ine and e lectr 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 facilit ies in accord­
ance w ith Aud i regulat ions.
The high voltage system is composed of the fol­ lowing h igh voltage components : the h igh volt­
age battery, the power electron ics, the e lectr ic
motor, the high voltage A/C compressor and the
orange high voltage wir ing.
High voltage 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 batte ry. Additional informat io n
about the h igh vo ltage battery can be found un­
der
¢ page 107 .
The high voltage battery service plug is also
found underneath an orange cover under the car ­
go floo r. The service plug is provided only 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 volt­
age component can result in a fatal electric
shock. The components in the high voltage
system are marked with a warning label which
warns against the h igh voltage .
- Never perform work on orange high voltage
cables or on high voltage components . Only
authorized repair fac ilities that are certified
may perform wo rk on the high voltage sys­
tem .
100
-Never open or remove the service plug cover
in the center of the cargo floor .
- Never damage, alter or
remove the orange
high voltage cable or disconnect it from the
high voltage system .
- Audi regulat ions 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 considerably less idling, driving and op­
erating noise than when the combust ion en­
g ine is running. Th is may make it difficu lt or
impossible fo r othe rs such as pedestrians and
chi ldren to hear and notice the vehicle when it
is in ele ct rical drive mode . Th is can lead to
collisions and inj uries, for example in low
traffic areas, when maneuvering or when driv­ ing 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 ca use coll is ions and severe or fatal
injuries . When the vehicle enters dr ive ready
mode , the status message
h) Jrid ih. J ap­
pears br iefly in the instrumen t cluster display
and the need le in the powe r meter points to
READ Y ¢page 101.
- When exi ting the vehicle, make su re these­
lecto r lever is in 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 . Immediately drive your
ve­
hicle to an authorized repair facility and
have it inspected.
- Do not transport fluids in open containers in
the luggage compartment. Spilled fluids
can seep underneath the cargo floor. Th is
can damage the high voltage system.

Vehicle not ready to start. See owner's
manual
This message appears if the high voltage battery
charge level is too low. The vehicle can no longer
be started with its own power. The high voltage
battery must be charged with a charger or the ve­
h icle must be jump started with the aid of anoth­
er vehicle.
After the connecting the charger or jumper ca­
bles, the ignition must be turned off for approxi­
mately two minutes and then turned on again .
After no more than one m inute, one of the fol­
lowing indicator lights turns on in the instrument
cluste r display .
B Charging battery. Please wait ...
If the indicator light turns on and this message
appears, the high voltage battery is charg ing or
the vehicle is be ing jump started with assistance
from another veh icle .
If the 12 volt batteries are dead, the- indi­
cator light turns on . The charging procedure
takes longer in this case because the 12 volt bat­
ter ies are charged first. The procedure goes fast­
er with the ig nition sw itched off.
Vehicle ready to start.
This message appears if the charging procedure
was successful. The vehicle may be started again .
Battery could not be charged enough to start
vehicle .
This message appears if the charging procedure
was not successful or it was interrupted. Th is
may happen if the charger or the battery in the
veh icle that is assisting is too weak.
If the veh icle
can not be started, see an authorized repa ir facil i­
ty for ass istanc e.
(D Tips
-The charger should deliver a current of at
l east 30 A. Otherwise charging the high
voltage battery will take considerably Ion-
108
ger. A current between 50 A and 70 A is ide ­
al.
- Th e veh icle that is assisting should be some­
what within the same vehicle class when
jump starting a vehicle. A smaller vehicle's
battery may be drained.
- After approximately 30 minutes, the charg­
ing procedure ends because the ignit ion is
automatically turned off. If you would like
to cont inue to charge the battery, turn the
ignition on again.

passenger seat is checked by the electronic con­
tro l unit when the ignition is on . The control unit
monitors the Advanced A irbag System and turns
the airbag indicator light on when a malfunct ion
in the system components is detected. The func­
tion of the airbag indicator l ight is descr ibed in
greater detai l below . Because the front passen­
ge r seat conta ins important parts of the Ad­
vanced A irbag System, you must take care to p re ­
ve nt i t from being damaged. Damage to the seat
may prevent the Advanced Airbag for the fron t
passenger seat from doing its job in a crash.
The front Advanced Airbag System consists
of the following :
-Crash sensors in the front of the vehicle that
measure vehicle acceleration/deceleration to
provide information to the Advanced Airbag
System a bout the severity of the crash.
- An e lectronic control unit, with integrated
crash sensors for front and side impacts. The
control unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors. The control unit a lso "de­
c ides" whether the safety belt pretens ioners
should be activated .
- An Advanced Airbag with gas generator and
control
valve for the driver ins ide the steer ing
wheel hub .
- An Advanced Airbag with gas generator and contro l
valve inside the instrument pa nel for
the front passenger.
- A weig ht-sensing mat under the upho lstery
padd ing of the front passenge r seat cushion
t h at meas ures the total weight on the seat. The
i nforma tion registered is sent continuously to
the e lectron ic cont rol unit to reg ulate dep loy­
ment o f the front Adv a need A irbag on the pas­
senger side .
- An airbag monito ring system and indicator
li ght in the instrument cluster
¢ page 158.
-A senso r in eac h front sea t registers the dis­
tance between the respective seat and the
steering wheel or instrument pane l. The infor­
mation reg istered is sent contin uously to the
electronic control unit to regulate deployment
of the front Adva need A irbags.
Airb ag sys tem
-The PASSENGER AIR BAG OFF light comes on
and stays on in the center of the instrument
pane l¢
page 159, fig . 167 and te lls yo u when
the front Advanced Airbag on the passenger side has been turned off.
- A sensor below the safety be lt latch for the
front seat passenger to measure the tension on the safety belt. The tension on the safety belt
and the we igh t registered by the weight -sens­
ing mat help the contro l unit "decide" whethe r
t he front airbag fo r th e fron t passe nger seat
should be tu rned off o r not ¢
page 149, Child
restrain ts on the front seat -some impor tant
things to know.
- A sensor in the s afety be lt latch for the drive r
an d for the front seat passenger that senses
whether tha t safety be lt is la tched o r not and
transmits this information to the e lectronic
control un it.
A WARNING ,-
Damage to the front passenge r seat can pre-
vent the front airbag from working properly.
- Improper repair or disassembly of the front
passenger and driver seat will p revent the
Advanced A irbag System from f unct ion ing
properly .
- Repairs to the front passenger seat must be
performed by qualified and p roper ly trai ned
wo rkshop personne l.
- Never remove the front passenger or d river
seat from the vehicle.
- Never remove the upholstery from the front
passenger seat.
- Never d isassemble o r remove parts from the
seat or disco nnect w ires from it.
- Never carry sharp objects in your pockets or
p lace them on the seat . If the weight-sens­
ing mat in the passenger seat is punctu red
it cannot work p roper ly .
- Never carry things on your lap or carry ob­
jects on the passenge r seat . S uch items can
increase t he weight reg istered by the
weight-sensing mat and s end the wro ng in­
formation to the a irbag con trol u nit.
- Never store i tems unde r the front passenger
seat. Parts of the Advanced Airbag System

Airbag syste m
-Never h old things i n your hands or on your
lap whe n the vehicle is in use.
- Never transport items on or in the area of
the front passenger seat. Objects could move into the area of the front airbags dur­
ing brak ing or other sudden maneuver and
become dangerous projectiles that can
ca use serious personal injury if the a irbags
inflate.
- Never place or attach accessor ies or other
objects (such as cupholders, telephone
brackets, large, heavy o r bulky objects) on
the doors, over or nea r the area marked
"AIRBAG" on the steering wheel, instru­
ment pane l, seat backrests or between
those areas and yourself. These objects could cause injury in a c rash, especially
when the airbags inflate.
- Never recline the front passenger's seat to
transport objects. Items can also move into
the area of the side airbag or the front a ir­
bag dur ing braking or in a sudden maneu­
ver. Objects near the airbags can become projectiles and cause injury, particularly
when the seat is reclined.
A WARNING
The fine dust created when airbags deploy can
cause breathing p roblems for people w ith a
his to ry of asthma or o ther b reathing condi­
tions .
- T o reduce the risk of brea thing problems,
those w ith asthma or o ther respiratory con­
ditions should get fresh air right away by
getting out of the vehicle or o pening win­
dows or doors.
- If you are in a collision in which airbags de ­
ploy, wash your hands and face with mild
soap and water before eat ing.
- Be careful not to get the dust into your eyes,
or into any cuts or scratches.
- If the resid ue should get into your eyes,
flush them with water .

Important safety instructions on

_& WARNING
An airbag system that is not funct ion ing prop­
er ly cannot provide supplemental p rotection
in a frontal crash.

- If the airbag indicator light r=> page 13
comes when the veh icle is being used, have
the system inspected immediately by your
author ized Audi dealer. It is possible that
the airbag will inflate when it is not sup­
posed to, or wi ll not inflate when it should.
_& WARNING
I f the front a irbag inflates, a ch ild without a
chi ld restraint, in a rea rward-facing chi ld safe­
ty seat or in a forward -fac ing chi ld restrain t
that has not been proper ly ins talled will be
seriously injured and can be killed .
- Even tho ugh you r vehicle is equipped with
an Advanced A irbag System, make certain
that a ll children, espec ia lly 12 years and
younger, always ride on the back seat prop­ erly restrained for their age and size.
- Always install forward or rear-facing child
safety seats on the rear seat -even with an
Advanced A irbag System.
- If you must insta ll a rearward-facing child
safety seat on the front passenger seat be­
cause of exceptional circumstances and the
PA SSEN GER AIR BA G OFF light does not
appear and stay on, immediately install the
rear-facing child safety seat in a rear seat ing
position and have t he a irbag system in­
spected by yo ur autho rized Aud i dea le r.
- A t ight tether or other strap on a rearward­
facing chi ld restraint attached to the front
passenger sea t can put too much pressure
on the weight-sensing mat in the seat and
register more weight than is actually on the
seat. The heavier weight registered can
make the system work as though an adu lt
were on the seat and deploy the Advanced
Airbag when it must be suppressed causing
serious or even fatal injury to the child.
- If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger seat, always move the
seat into its rearmost position in the seat 's
fore and aft ad justment range, as far away
from the airbag as poss ible. The back res t
m ust be adjus ted to an upr ight position.
