pears briefly in the instrument cluster display
and the needle in the power meter points to
READY ¢ page 9 5.
-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
93

e-tron
for the high voltage battery can lead to seri­
ous damage and/or a decrease of the capacity
void coverage under the New Vehicle Limited
Warranty.
