Introduction
Applies to: vehicles with plug-in hybrid drive
General information
The plug- in hybrid drive is a drive concept that al­
lows you to choose between driving w ith the elec­
tr ic moto r, with the gaso lin e eng ine o r us ing a
comb inat io n of both.
All work done on the high-voltage system must
only be performed by certif ied h igh-voltage tech­
n icians at autho rized Aud i dea le rs or authorized
Aud i Serv ice Facilities in accordance with A udi
gu idelines.
The high-voltage system is composed of the fol­ low ing high-voltage components: the h igh -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 -vo ltage
wiring.
The pedal referred to in this sect ion of the Own­
er's Manua l is t he equivalent of the acce lerator
pedal (gas peda l) in a standard vehicle.
High-voltage battery
The high -voltage battery is located on the veh icle
underbody in front of t he rear ax le and does not
require any maintenance from t he d river. Addi ­
tional information about the high-vo ltage bat ­
tery can be found
under ¢ page 106.
A WARNING
The voltage in the h igh-vo ltage system is life­
threaten ing. 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 w ith a warning label wh ich
wa rns against t he h igh-vo ltage.
- The voltage level in the high-voltage system
is still dangerous and potent ially life-threat­
ening when t he ignit ion is switched off.
- Never perform work on orange high-voltage
cables or on high-voltage components. Only
92
authorized repair facilities that are certified may perform work on the high-vo ltage 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 cutting, shap­ ing or sharp-edged too ls or heat sources
near the h igh-vo ltage system and hig h-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 t he h igh-voltage 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
r is k of t he ignit io n be ing inadve rtent ly
sw itched on.
- Gases t hat escape from the high-vo ltage
b attery can be poisono us or flammab le.
- Damage to the h igh-voltage battery could
cause t he hi gh-vo ltage battery to lea k im­
mediately or in the fut ure, and poisono us or
flammab le gases co uld 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 h igh -voltage battery e lec troly te flui d is
caustic. If electro lyte fluid comes into con ­
tact with the skin, flus h the affected area
for at least 15 minutes with clean water.
Then wash the affected area with soap.
H ave the affected area examined by a med i­
cal professional.
- In the event of a technica l emergency, in­
form the responders that the vehicle is
equ ipped with a high-voltage battery.
A WARNING
Neve r leave the vehicle unattended when in
drive ready mode
¢ page 94 with a gea r en­
gaged . T he veh icle can start mov ing ("creep­
i ng") even if the gaso line engine is swi tched
off, since the e lectr ic motor is still ope ra ting.
