(D Tips
-Air condit ioning and heating is powered
electrically if you select climate control us­
i ng the charging timer . This may also be
used in confined spaces such as garages .
-Using the auxiliary air conditioning wh ile
charging can also reduce the charge level of
the high-vo ltage battery.
-The high-voltage battery also charges in
power save mode .
-If the charging process is in progress, it will
not be interrupted when power save mode
switches on.
-The charging process can be interrupted at
any time . Press the active button on the ve­
hicle to do
this ~ page 111, fig. 122.
-The cl imate control output wh ile charging
depends on the capacity of the electrical
connection . Additional information on cl i­
mate control can be found under
~ page 118.

(D Tips
-If a household socket is used for the charg­
ing process, the cha rging power level is au­
t oma tically set to 100%. If m ultip le electri­
cal consumers are connected to a circu it,
the charging power may be limited to 50%
when charging with a household socket in
order to relieve the load on the electrical in­
stallation.
-If an industrial socket is used for the charg­
ing process, the charging power level is au­
tomatically set to 50%. To rece ive the maxi­
mum charging power, the value must be set
to 100% .
-A selected value remains set until the power
cable is connected again .

enough fuel in the tank.
(D Tips
-T he tem perature that the climate con trol
system adjusts to depends on the last tem­
perat ure yo u set in the climate contro l unit
¢ page 71 .
-Using the auxiliary air conditioning while
charging can a lso reduce the charge level of
the high -voltage battery.
-T he climate cont rol system does not auto­
matically switc h on or off earlier if the hig h­
voltage battery charge o r fuel leve l is too
low .

Cleaning/maintenance
information
Appl ies to : vehicles wi th plug-in hybrid drive
When was hing your vehicle with a pressure wash­
er, always follow the operat ing instruct ions pro­
vided with the pressure washer . This is especially
i mportant in regard to the pressu re and spray ing
distance. Do not dire ct cleaning spray at the
charg ing unit in the rad iator g rille or at t he
charg ing dock*/charging cl ip *. Keep a d istance of
a t least 16 in (40 cm) .
Do not remove snow and ice with a pressure
washer .
Never use cone nozzles or high pressure nozzles .
The water temperature must not be above 60
°C.
Remove contaminants on the Audi e -tron system
with a dry towel.
Remove contaminants on the charging do ck*/
charg ing clip* wi th a wet towel dampened w ith
alcohol-free clean ing solution .
A WARNING ~
-Never immerse t he Audi e-tron charging
system and connecto rs in water.
- The A udi e -tron charging system must on ly
be cleaned when the control unit is com­
p letely disconnected from the power supp ly
and from the vehicle.
(D Note
To dec rease the risk of discoloration, never
clean the c harging doc k*/charging clip * with

-If tests need to be performed with the en­
gine running, there is additional danger due
to moving components (such as the ribbed belt, alternator and radiator fan) and from
the high-voltage ignition system.
-Never reach into the radiator fan. The elec­
tric auxiliary fan is controlled by tempera­
ture and can switch on suddenly.
-Do not under any circumstances activate the
throttle inadvertently (for example, by hand
from the engine compartment) if the vehi­
cle is stationary but the engine is running
and a gear is engaged. Otherwise, the vehi­
cle will start to move immediately and this
could result in an accident.
-Pay attention to the following warnings list­
ed when work on the fuel system or on the
electrical equipment is required.
- Do not smoke .
-Never work near open flames.
- Always have a working fire extinguisher
nearby
- All work on the battery or electrical system
in your vehicle can result in injuries, chemi •
cal burns, accidents or burns. Because of
this, all work must be performed
only by an
authorized Audi dealer or authorized Audi
Service Facility.
-To reduce the risk of electric shock and in­
jury, never touch the following components when the engine is running or is being start­
ed :
- Ignition cable
-Other components in the electronic high-
voltage ignition system
-If you must check or perform work on the
engine while it is running:
-Set the parking brake and place the selec­
tor lever in the P (park) position first .
- Always proceed with extreme caution so
that clothing, jewelry or long hair do not
become caught in the radiator fan, fan
belt or other moving components or do
not come into contact with hot compo­
nents. Tie back long hair before beginning
work and do not wear clothing that can
hang down into the engine .
Checking and Filling
-Limit your exposure to exhaust and chemi­
cals to as short a time as possible
c:> A .
A WARNING
-California Proposition 65 Warning:
-Engine exhaust, some of its constituents,
and certain vehicle components contain or
emit chemicals known to the State of Cali­
fornia to cause cancer and birth defects and
reproductive harm . In addition, certain flu­
ids contained in vehicles and certain prod­
ucts of component wear contain or emit
chemicals known to the State of California
to cause cancer and birth defects or other
reproductive harm.
- Battery posts, terminals and related acces­
sories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harms.
Wash hands after handling.
(D Note
When filling fluids, be sure not to mix the flu­
ids up. Otherwise severe malfunctions and en­
gine damage will occur.
@ For the sake of the environment
You should regularly check the ground under
your vehicle in order to detect leaks quickly. If
there are visible spots from oil or other fluids, bring your vehicle to an authorized Audi deal­
er or authori zed Audi Service Facility to be
checked.

A WARNING
=
-If the brake fluid level is below the MIN
marking, it can impair the brak ing effect
and d riving safety, wh ich increase the risk of
a n accident . Do no t continue dr iving . See a n
a uthor ized Audi dealer or author ized A udi
Serv ice F acility for a ssistance.
- I f the b rake fl uid is old, b ubbles may form
i n t he bra ke sys tem dur ing heavy bra king.
This wo uld impair braking per formance an d
d riving safety, which increases the r is k of an
accident.
- T o ensu re the brake system fu nctions cor­
rectly, only use brake fluids that comp ly
with VW standard 501 14 or F M VSS -116 DOT 4.
(D Note
- If the brake flu id leve l is above the MAX
marking, bra ke f luid may leak o ut over the
edge of the reservo ir and result in damage
to the vehicle.
- Do not get any b rake fl uid on the vehicle

Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you.
It is becoming increasingly more and more diffi­
cu lt to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­
moved before you are able to get to the bulb.
This applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment.
Sheet meta l and bulb holders can have sharp
edges that can cause serious cuts, parts must be
correctly taken apa rt and then properly put back
together to help prevent breakage of parts and
