-Make sure that the selector lever is in the P
position and the ignition is switched off
when leaving the vehicle.
@ Note
-The high-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.
- The electric drive motor can become very
hot during operation . Do not stop the vehi­
cle if there is oil, fuel residue or other flam­
mable substances under or next to the vehi­
cle.
Special considerations for the high-voltage
battery
Applies to: vehicles with plug-in hybrid drive
Please first read and note the introductory infor­
mation and heed the warnings
¢page 92.
All batteries age with use and over time. There
are things you should know about the care of the
high voltage battery that will help it keep giving
you good service and reliability over time. Please
read and keep the following information in mind
while you enjoy the performance and economy of
your vehicle.
- Be sure to charge the high voltage battery be­
fore leaving the vehicle parked and unused for a longer period of time. Ideally the high-voltage
battery should have a charge level between
40 % and 60 % when parked for a long t ime .
- If the battery charge level is below 3 %, never
park the vehicle for more than 21 days without
charging the high-voltage battery. Should you
have to park the vehicle for a long time, make
sure that the charge level is sufficient to help
prevent the battery from aging prematurely.
- Frequent and consecutive charging of the high­
voltage battery when the charge level is above
e-tron
98 % can also decrease the capacity of the
high-voltage battery. Make sure the charge lev ­
el is be low 98 % when you start the charging
process.
- Should the vehicle be parked for longer than
2 days at temperatures below -13 °F ( -25 °C),
the high-voltage battery could free ze and not
be able to provide energy to the electric motor.
The battery will start working again, once it
warms up . The battery can be warmed up when
the outside temperature rises or when the vehi­
cle is garaged appropriately. The battery will al­
so warm up when being used (sw itching on the
air conditioner, the heater or by driving the ve­
hicle) . Should you have to park your vehicle at
very low temperatures for longer than 1 day,
make sure that the high-voltage battery does
not freeze by parking the vehicle in a garage
that is heated or protected from the outside
temperature.
- The high-voltage battery can be damaged and
the capacity can be decreased when the vehicle
is parked for longer than 24 hours when the
ambient temperature is higher than 118 °F
(48 °C). Always make sure that the h igh-volt­
age battery is not exposed to temperatures
above 118 °F (48 °C) for a long time.
- Never park the veh icle in areas that are lik ely to
be flooded, such as beaches or river banks, and
never drive the vehicle in WA TER, on flooded
roads or through water that is higher than the
bottom of the vehicle body. The high-voltage
battery, along with other vehicle components,
can be damaged severely if the high-voltage battery is exposed to open water especially for
a longer time. However, you can drive through
water on roads under certain conditions
~ page 72.
Failure to heed any of these requirements can
age the battery prematurely and lead to a perma­
nent decrease of the high-vo ltage battery's ca­
pacity.
(D Tips
Always make sure that the high-voltage bat­
tery is not exposed to extremely low and high
temperatures as well as to water espec ially
for a longer time. Failure to protect and care

Checking and Filling
If the recommended engine oil is not available,
in an eme rg enc y you may add a maximum of 1
quart(! liter) of ACEA C3 or API SN engine oil
one tim e until the next oil change.

Areas on the o il dipstick 9 fig . 268 .
(D If the engine oil leve l is just before the
mark ing
(D , then engine oil must be added .
See¢@.
@ Do not add engine oil.
(D Note
- T he engine o il level must not be below the
ma rking
(D , because this increases the risk
of engine damage.
- After add ing engine oil, the oil leve l must
not be above the marking @, because this
increases the risk of catalytic converter and/
or engine damage . Do not start the engine .
Contact an authorized Audi dealer or au­
thorized Audi Service Facility to have excess eng ine oil extracted if necessary .
(D Tips
- The engine oil consumption may be up to
0.5 quart/600 miles (0.5 liter/1,000 km),
depending on driving style and operating
conditions. Consumpt io n may be h igher
dur ing the fi rst 3,000 mi les (5,000 km) . Be­
c ause of this , the eng ine o il level must be
che cked regularly.
It is best to check each
t ime you refuel your vehicle and before long
drives .
- In order to prov ide effective l ubrication and
cooling of interna l engine components, a ll
internal combustion engines consume a cer ­
tain amount of oil. O il consumption varies
from engine to engine and may change sig­ nificantly over the life of the engine. Typi­
cally, eng ines with a specif ied break-in peri­
od consume more oil during the break-in pe ­
riod than they consume after o il consump­
t ion has stabilized .
- Under normal condit ions, the rate of oil
cons umption depends on t he quality and
viscosity of the oil, the RPM (revo lutions per
mi nute) at which the engine is ope rated, the
ambien t temperature and road conditions .
Further factors are the amount of oi l dilu­
tion from water condensation or fuel resi­ due and the oxidation level of the oil. As any
eng ine is subject to wear as m ileage builds
Ii>-

u. 00 .-< N l'­ N .-< 0 N > 00
up, the oil consumption may increase over
time unti l replacement of worn components
may become necessary .
- With a ll these variab les coming into p lay,
no standard rate of oil consumption can be
estab lished or specified. There is no alterna­
tive to checking the o il level regu larly and
frequently.
- If you have the impression your engine con ­
sumes excessive amounts of oil, we recom­ mend that you consult an authorized Aud i
dealer to have the cause of your concern properly d iagnosed . Keep in mind that the
accu rate measurement of oil consumption
r equ ires gre at ca re and may take some
time. An a uthorized Audi dea ler has instruc­
tions about how to measure oil consump ­
tion acc urately.
