e-tron Plug-in hybrid drive
Introduction
A pp lies to: ve hicles w ith plug -in hybrid drive
General information
The plug- in hybrid drive is a drive concept that al­
lows yo u to choose between driving w ith the elec­
tr ic moto r, with the gaso lin e engine o r using a
comb inat io n of both.
All work done on the high-voltage system must
only be performed by certified high-voltage tech­
n icians at autho rized Aud i dea le rs or authorized
Aud i Serv ice Facilities in accordance with Audi
gu idelines.
The high-voltage system is composed of the fol­ low ing h igh-vo ltage components: the high-volt­
age battery, the powe r electron ics, the e lectr ic
motor, the high-voltage A/C compressor, the
high-vo ltage heater, the charging system and
charging port as well as the orange high-voltage
wiring.
The pedal referred to in this sect ion of the Own­
er's Manua l is the equivalent of the acce lerator
pedal (gas pedal) in a standard veh icle.
High-voltage battery
The high-voltage battery is located under the
rear bench seat in the veh icle and does not re­
qu ire any maintenance from the driver. Addition ­
a l information about the high-voltage battery can
be found under
Q page 108 .
A WARNING
The voltage in the high-vo ltage system is life­
threatening. Touching a damaged high-volt­
age component can result in a fatal e lectr ic
shock. The components in the high-voltage
system are ma rked with a warning label which
wa rns against the h igh-vo ltage.
- The voltage level in the high-voltage system
is still dangerous and potentially life-threat­
ening when the ignition is switched off.
- Never perform work on orange high-voltage
cables or on high-voltage components. Only
94
authorized repair facilities that are certified may perform work on the high-voltage sys­
tem.
- Never damage, alter or remove the orange
high-voltage cable or disconnect it from the
high-voltage system.
- Never perform any work using c utting, shap­
ing or sharp-edged too ls or heat sources
near the h igh-vo ltage system and high-volt­
age cables.
- Aud i regulat ions must be followed during
all work performed on the high-voltage sys­
tem and h igh-vo ltage components.
- When working on the h igh-vo ltage system
and h igh-voltage compone nts, make sure
the remote cont rol key is kept far enough
away from the vehicle so that there is no
ris k of the ignit ion be ing inadve rten tly
sw itched on.
- Gases that escape from the high-vol tage
b attery can be poisono us or flammable.
- Damage to the high-voltage battery could
cause the h igh-vo ltage battery to leak im­
media tely or in the fu ture, and poisonous or
flammab le gases cou ld escape . Do not in ­
ha le the gases!
- Do not expose yourse lf to any leaking fluids
and do not come into contact with them .
- The high-volt age battery e lectroly te fl uid is
caustic. I f electrolyte fluid comes into con ­
tact with the sk in, f lush the affected area
for at least 15 minutes with clean water.
Then wash the affected area with soap.
Have the affected area examined by a med i­
cal professional.
- In the event of a technical emergency, in­
form the responders that the vehicle is
equ ipped with a high-voltage battery.
A WARNING
Never leave the vehicle unattended when in
drive ready
mode ~ page 96 with a gear en­
gaged . The veh icle can start moving ("creep­
ing") even if the gaso line engine is switched
off, since the e lectr ic motor is still operating.
This may cause collis ions and severe or fatal

Monitoring the
Advanced Airbag System
Airbag monitoring indicator light
Two separate indicators monitor the function of
the Advanced Airbag System: the
E,I light and
the
PA SSEN GER AIR BAG OFF light.
The Advanced Airbag System as we ll as the side
airbags and side curtain airbags with eject io n
mitigation feat ures (incl uding the e lectronic con­
trol unit, sensors and system wiring) are all
monitored continuously to make sure that they
are functioning properly whenever the ignition is
on. Every t ime yo u turn on the ignition, the air­
bag system indicator light
m will come on for a
few seconds (function check) .
The s yste m must b e in spect ed wh en th e
indicato r light
El:
- does not come on when the ignition is switched
on,
- does not go out a few seconds after you have
switched on the ign ition, or
- comes on while driving.
I f an airbag system malfunction is detected, the
indicator light wi ll come o n to serve as a constant
reminder to have the system inspected immedi­
ately .
I f a malfunction occurs that turns the front air­
bag on the passenger side off, the
PA SSENGER
AIR BAG OF F
light will come on and stay on
whenever the ignition is on.
A WARNING
An airbag system that is not funct ion ing prop­
erly cannot provide supplemental p rotection
in a frontal crash.
- If the airbag indicato r light
c:> page 29
comes when the vehicle is be ing used, have
the system inspected immed iate ly by your
authori zed Aud i dealer.
It is possible that
the a irb ag will inf late w hen it is not sup­
posed to, or will not infla te whe n it shou ld .
Airb ag sys tem
PASSENGER AIR BAG OFF light
Fig. 2 44 Center console: passenger airbag off warning
light
T he PAS SENGER AIR BAG OFF light is located in
the cente r of the instrume nt panel
c:> fig . 244.
T he PASS ENGER AIR BAG OFF light w ill come o n
and stay on to tel l you when the front Advanced
Airbag on the passenger side has been turned off by the e lectronic control unit. If the b ulb for the
PASSENGER AIR BAG OFF light burns out, the
airbag indicator light
m will come on to signal a
malfunction in the Advanced Airbag System. Al­
though the burned-out bulb w ill not change the
way the front passenger's frontal airbag works, it
will no longer be possible to use the
PASSENGER
AIR BAG OFF
light to make sure that the a irbag
o n/off status is correct for the occupan t on the
front passenge r seat. Have the airbag system in­
spected imme diately by your au thori zed Audi
dealer.
The PASSENGER AIR BAG OFF light will blink
for about 5 seconds when:
- the ignition is sw itched on and
- the capacit ive passenger detection system,
which switches the front seat passenger's fron­
tal Advanced Airbag on and off, detects a
change i n the status of the front passenger
seat.
As soon as the
PA SSENGER AIR BAG OFF light
stops blinking, always make sure that the a irbag
status (on or off) as shown by the
PAS SENGER
AIR BAG OFF
light is proper for the age, si ze and
electrical cap acitance of the pe rson occ upying
the front passenger seat. A lways make s ure that
the safety be lt fo r the front passenger seat is
properly fastened.
