Opening and closing

the vehicle within a short time to remove
the vehicle key, then the vehicle will lock au-
tomatically. This prevents the vehicle from
being left unlocked for long periods of time.
The key will then be locked inside the vehi-
cle.
— If the convenience key* that was used last is
detected inside the luggage compartment,
it will not be possible to lock the luggage
compartment and the luggage compart-
ment lid will open. The turn signals will
flash several times to indicate this. The
doors will lock. Always take the convenience
key with you, or unauthorized people may
be able to enter the vehicle.
@ Tips
— Do not leave valuables unattended in the ve-
hicle. A locked vehicle is not a safe!
— The LED in the driver's door rail blinks when
you lock the vehicle. If the LED lights up for
approximately 30 seconds after locking,
there is a malfunction in the central locking
system. Have the problem corrected by an
authorized Audi dealer or authorized Audi
Service Facility.

Fig. 18 Your vehicle key set
Remote or convenience key*
The convenience key* is a remote control key with
special functions > page 28 and > page 71.
You can unlock/lock your vehicle with the remote
control key. To fold the key out and back in place,
press the release button > fig. 18.
26
Number of keys
You can check the number of keys assigned to
your vehicle in the Infotainment system. To do
this, select the [MENU] button > Vehicle > left
control button > Service & checks > Vehicle in-
formation. This way, you can make sure that you
have all the keys when purchasing a used vehicle.


Replacing a key
If a key is lost, see an authorized Audi dealer or
authorized Audi Service Facility. Have this key de-
activated. It is important to bring all keys with
you. If a key is lost, you should report it to your
insurance company.
Electronic immobilizer
The immobilizer prevents unauthorized use of
the vehicle. Under certain circumstances, the ve-
hicle may not be able to start if there is a key
from a different vehicle manufacturer on the key
chain.
Data in the master key
During driving, data that is relevant for service
and maintenance is continuously stored on your
master key. Your Audi service advisor can read
out this data and tell you about the work your ve-
hicle needs. This applies also to vehicles with a
convenience key*.
@) Note
Protect the remote control key against high
temperatures, direct sunlight, and moisture.
@) For the sake of the environment
° Do not dispose of remote control keys in
household trash. They contain materials that
can be recycled. Contact an authorized Audi
dealer or authorized Audi Service Facility for
more information.
Gi) Tips
— The operation of the remote control key can
be temporarily disrupted by interference
from transmitters near the vehicle working
in the same frequency range (such as a cell
phone or radio equipment). Always check if
your vehicle is locked.

Driving

— Turn off electrical equipment that is not need-
ed, for example seat heating*.
— Anticipate upcoming traffic situations while
driving to avoid unnecessary acceleration and
braking.
— Avoid driving at high speeds.
— Avoid adding extra weight to the vehicle if pos-
sible, for example by not leaving roof racks or
bike racks installed when they are not needed.
— Make sure the tire pressure is correct.
— Have maintenance performed regularly on the
vehicle.
— Do not drive with winter tires during the summ-
er.
— Do not let the engine run while the vehicle
parked.
— Use the Start/Stop system.
— Utilize the engine braking effect.
— Avoid driving short distances when possible.
— Plug-in hybrid drive: brake early and evenly to
use the recuperation function.
@) Tips
The amount of noise produced by the vehicle
can increase significantly when driving with a
sporty style. Show respect to others around
you and the environment with the way you op-
erate your vehicle, especially at night.
Energy management
Your vehicle is equipped with an intelligent ener-
gy management system for distributing electrici-
ty. This significantly improves the starting ability
and increases the vehicle battery life.
G) Tips
— If you drive short distances frequently, the
vehicle battery may not charge enough
while driving. As a result, convenience func-
tions for electrical equipment may be tem-
porarily unavailable.
— The vehicle battery will gradually drain if
the vehicle is not driven for long periods of
time, or if electrical equipment is used
when the engine is not running. To ensure
that the vehicle can still be started, the
82
electrical equipment will be limited or
switched off.
S Engine stopped: power steering and brake
booster not possible
There is a malfunction in the engine or the fuel
supply. More force is needed to steer and brake
the moving vehicle when the engine is stopped.
If the vehicle is rolling, try to bring it to a stop off
to the side from moving traffic. See an author-
ized Audi dealer or authorized Audi Service Facili-
ty for assistance.
EB EB Drive system: malfunction! Safely stop
vehicle
There is a malfunction in the plug-in hybrid sys-
tem. The brake booster and the power steering
may stop working. Stop the vehicle immediately
at a suitable location or as soon as possible. Park
the vehicle in a safe place outdoors that is not
near buildings, roof overhangs, carports or simi-
lar structures. Switch the ignition off. Have the
problem corrected by an authorized Audi dealer
or authorized Audi Service Facility.
B i B Electric drive: overheated! Safely stop
vehicle and check coolant
The coolant level is too Low or the coolant tem-
perature is too high. Stop the vehicle in the out-
doors as soon as it is safely possible. Switch the
ignition off.
Read the important safety precautions > A in
Coolant on page 312 and check the coolant level
= page 312. If the coolant level is OK, the mal-
function may be caused by the system overheat-
ing. Let the vehicle's electric drive system cool
down for some time.
— If the message turns off after cooling down and
switching the ignition back on, you can contin-
ue driving. Contact an authorized Audi dealer or
authorized Audi Service Facility immediately to
have the malfunction corrected.
— If the indicator light stays on, contact an au-
thorized Audi dealer or authorized Audi Service
Facility.

High-voltage system

High-voltage system
General information
Introduction
Applies to: vehicles with plug-in hybrid drive
All work done on the high-voltage system must
only be performed by certified high-voltage tech-
nicians at authorized Audi dealers or authorized
Audi Service Facilities in accordance with Audi
guidelines.
The high-voltage system is composed of the fol-
lowing high-voltage components, among other
things: the high-voltage battery, the power elec-
tronics, the electric motor, the high-voltage A/C
compressor, the high-voltage heater, the charg-
ing system and charging port, and the orange
high-voltage wiring.
The high-voltage battery is located on the vehicle
underbody in front of the rear axle and does not
require any maintenance from the driver.

ZA WARNING
The voltage in the high-voltage system is life-
threatening. Touching a damaged high-volt-
age component can result in a fatal electric
shock. The components in the high-voltage
system are marked with a warning label which
warns against the high-voltage.
— 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 the orange high-
voltage cables or on other high-voltage
components. Only authorized repair facili-
ties that are certified may perform work on
the high-voltage system.
— 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 tools or heat sources
near the high-voltage system and high-volt-
age cables.
— Gases that escape from the high-voltage
battery can be poisonous or flammable.

96

— Damage to the high-voltage battery could
cause the high-voltage battery to leak im-
mediately or in the future, and poisonous or
flammable gases could escape. Do not in-
hale the gases!
— Do not expose yourself to any leaking fluids
and do not come into contact with them.
— The high-voltage battery electrolyte fluid is
caustic. If electrolyte fluid comes into con-
tact with the skin, flush 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 medical profes-
sional.
— In the event of a technical emergency, in-
form the responders that the vehicle is
equipped with a high-voltage battery.
@) 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 96.
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 >
