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.

164 Airbag sys te m
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the a irbag as poss ible, before insta lling
the forward-facing child restraint. The backrest must be adjusted to an upr ight
posit ion.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
t ime w henever the ignition is switched
on.
Advanced Airbag System components
The fron t passenger sea t in your vehicle h as a
lot of very important par ts of the Advanced
Airbag System in it. These parts include t he
weight -sensing mat, sensors, wiring, brack­
ets, and more. The function of the system in
the front passenger seat is checked by the
e lectronic control un it when the ignit ion is on.
The control unit mon itors the Advanced Air­
bag System and turns the airbag indicator
l ight on when a ma lfunction in t he system
components is detected. The func tion of the
a ir bag ind icator light is described in greater
detai l be low . Because the front passenger
seat contains important parts of the Ad­
vanced A irbag System, you m ust take care to
prevent it from be ing damaged. Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag Sy stem
consists of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/deceleration
to provide information to the Advanced Air­
bag System abou t the seve rity of the crash.
- An electron ic co ntrol unit, with integ rated
crash sensors for front and side impacts .
T he cont ro l unit "dec ides " w het her to fire
the front airbags based on the information
received from the crash senso rs . The contro l
unit a lso "decides" whethe r the safety be lt
pretensioners should be activated . -
An Advanced A irbag w ith gas generator and
cont ro l valve for the d river inside the steer­
ing wheel h ub.
- An Advanced A irbag with gas ge nerator and
contro l valve inside the instrument pane l for
the front passenger.
- A weight-sensing mat under the up ho lstery
pad ding of the front passenger seat cushion
that measures the total weight on the seat.
The informat ion registered is sent continu­
ously to the electronic contro l unit to regu­
late deployment of the front Advanced Air­ bag on the passenger side .
- An airbag monitor ing system and i ndicator
light in the i nstr ument cluster ~
page 168 .
-A sensor in each front seat registers the dis­
tance between the respective seat a nd the
steer ing whee l o r i ns trument panel. The i n­
formation registered is sent cont inuously to
t he ele ctr onic cont ro l uni t to regula te de­
p loyment o f the front Advance d Airbags .
- The
PASSENGER AIR BAG OFF ligh t comes
on and st ays on in the cen ter o f the instr u­
ment panel
~ page 168, fig . 169 and tells
you whe n the front Advanced Airbag on the
passenger side has been tu rned off .
- A sensor below the safety be lt latch for the
front seat passenger to measure the tension on the safety be lt . The tension on the safety
be lt and the weight registered by the
weight-sensing mat he lp the control unit
"decide" whether the front airbag for the
front passenger seat should be turned off or
not

Monitoring the
Advanced Airbag System
Airbag monitoring indicator light
Two separate indicators monitor the function
of the Advanced Airbag System: the airbag
monitoring indicator light and the
PASSEN ­
GER AIR BA G OFF
light.
The Advanced Airbag System (including the
electronic control unit, sensor circuits and sys­
tem wiring) is monitored continuously to
make sure that it is functioni ng properly
whenever the ignit ion is on. Each t ime you
turn on the ignition, the airbag monitoring in­
d icator light
fl will come on fo r a few seconds
(self diagnosti cs) .
The system must be inspected when the
indicator light
fl:
- does not come on when the ignit ion is
swit ched on,
- does not go out a few seconds after yo u
have swi tched on the ign ition, o r
- comes on w hile d riving .
If an airbag system malfunction is detected,
the indicator light will first start flash ing to
catch the driver's atte ntion and then stay on
continuously to se rve as a constant reminder
to have the system inspected immediately .
If a malfunction occurs that turns the front
a irbag on the passenger side off, the
PASSEN­
GER AIR BAG OFF
li ght will come on and stay
on whenev er the ignition is on.
A WARNING
An air bag system that is not func tioni ng
prope rly ca nnot provide supplemen tal p ro­
t ect ion in a fron tal cr ash .
-If the airbag indic ator light¢ p age 15
comes whe n the vehicle is be ing used,
have t he system inspected immediate ly
by yo ur aut ho rized Aud i dea ler . It is pos­
sible that the a irbag will inf late when it
is not s upposed to, or w ill not inflate
when it should.

212 Trailertowing
Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a trai ler, p lease remember
that the additional load will affect durability,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
For this reason, always fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
T ra ile r hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­
ble for your vehicle and trailer and mu st be
mounted securely on the veh icle's chassis at a
technically sound location. Use only a trailer
h itch with a removable ball mount. A lways
check with the trai ler h itch manufact urer to
make sure that you are using the correct
hitch.
Do n ot use a bumper hi tch.
The hitch must be installed in such a way that
it does not interfere with the impact-absorb­
ing bumper system . No modifications should
be made to the vehicle exhaust and brake sys­
tems . From t ime to time, check that all hitch
mounting bo lts remain securely fastened.
When you are not towing a trailer, remove the
trailer h itch ball mount. This prevents the
h itch from causing damage should your veh i­
cle be struck from behind
¢ A .
Traile r brak es
If your tra iler is equipped w ith a braking sys­
tem, check to be sure that it conforms to a ll
regulat ions . The trailer hydraulic brake system must not be
direct ly connected to the vehicle's hydraulic
brake system
~ A .
Saf ety ch ain s
Always use safety chains between your veh icle
and the trai le r.
Trail er light s
Trailer lights must meet all regulations. Be
sure to check w ith your authorized Audi dealer
for correct wiring, sw itches, and relays.
Mirror s
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors .
It is important
that you always have clea r vis io n to the rear.
,8. WARNING
- I f a trai ler has electrical brakes p lease
note that these brakes are not activated
by the factory -fitted control unit -risk of
accident!
- Afte r removing the trailer hitch, do not
store it in your vehicle. In case of sudden
braking, the hitch could fly forward and
injure you or your passengers.
- Never install a "weight distributing" or
"load equalizing" trailer hitch on your ve­
h icle. The vehicle was not designed for
these kinds of trailer h itches. The h itch
attachment can fail, caus ing the trailer
to tear loose from the veh icle.
- The Gross Vehicle Weight Rating for your
veh icle, found on the safety compliance
label on the driver's s ide B-pillar, must
never be exceeded under any c ircumstan­
ces. Exceeding the Gross Vehicle Weight
Rating of yo ur vehicle is likely to damage
your vehicle, and such damage will not
be covered by yo ur Limited New Ve hicle
Warranty . Exceeding the Gross Vehicle
Weight Rating will a lso change the per­
formance and handling characteristics of
your veh icle, wh ich could cause a crash
resulting in serious injury or death.
