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
insu rance company.
Number of keys
You can check the number of keys assigned to
your vehicle in the Infotainment system . To do
this, select the
IM ENU I 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.
Electronic immobilizer
The immob ilizer prevents unauthorized use of
the vehicle .
Under certain circumstances, the vehicle may not
be able to start if there is a key from a different
veh icle manufacturer on the key chain.

Data in the master key
When dr iving, service and maintenance-re levant
data is continuously stored in your remote con­
trol key. Your A udi service advisor can read out
this data and tell you about the work your vehicle needs . This applies also to vehicles with a con­
venience key*.
Personal convenience settings
If two people use one vehicle, it is recommended
that each person always uses "their own" master
key . When the ign ition is turned off or when the
vehicle is locked, personal convenience settings
for the following systems are stored and as­
s igned to the remote master key.
- Climate control system
-Steering wheel heating*
-Central lockin g system
-Interior lighting*
-Exter ior lighting
- Rain sensor
- Memory function*
- Park ing a id *
-Adaptive cr uise control *
-Active lane assist*
-Side assist*
-Traff ic jam assist*
- Distance warning*
-Audi pre sense*
- Speed warning *
The stored settings are automatically recalled
when you unlock the vehicle, open the doors or
turn on the ignition .
~ WARNING
Always take the vehicle key with you when
leaving the vehicle, even for a short period of
time. This applies particularly when children
rema in in the vehicle . Otherwise the children
could start the engine or operate electrical
equipment such as power windows .

snow and ice. Always read and follow safety
precautions¢.&. .
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions. However, using winter or all season tires
on
all four wheels in the winter is recommended,
because this will improve the
braking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
¢ page 358, Snow chains.
Replacing tires
For vehicles with all wheel drive, only wheels with
the same rolling circumference should be used.
Avoid using tires with different tread depths
¢ page 348, New tires or wheels.
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficult terrain .
A WARNING
-Also, in vehicles with all wheel drive, adapt
your driving style to the current road and
traffic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the risk of an acci­
dent .
- The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi­
cle. Do not be tempted to accelerate to a
high speed when the road is slippery, be­
cause this increases the risk of an accident .
- Note that on wet streets, the front wheels
can "hydroplane" if driving at speeds that
are too high. Unlike front wheel drive
vehicles, the engine does not rev higher sud­
denly when the vehicle begins hydroplaning.
For this reason, adapt your speed to the
road conditions to reduce the risk of an acci­
dent.
Intelligent Technology
Energy management
The starting ability is optimized
T he energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engtne.
When a vehicle with a conventional energy sys­
tem is not driven for a long time, the vehicle bat­
tery is drained by equipment (for example, the
immobilizer). In certain circumstances , there
could may not be enough energy to start the en­
gine.
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.
The energy management system Is made up of
battery diagnosis, idling current management,
and dynamic energy management.
Battery diagnosis
The battery diagnosis determines the vehicle bat­
tery charge level. The sensors determine the bat­
tery voltage, the battery current, and the battery
temperature. The current charge level and the
performance of the vehicle battery are deter­
mined based on this.
Idling current management
The idling current management decreases the
energy used while parked. With the engine
switched off, it manages the energy distribution
to the different electrical components . Data from
the battery diagnosis is taken into account for
this.
Depending on the vehicle battery charge level,
electrical equipment is switched off one item af­
ter the other to prevent the vehicle battery from draining and to maintain the starting ability.
Dynamic energy management
While driving, dynamic energy management dis­
tributes the appropriate amount of energy to the
electrical equipment.
It controls the battery
charge level so that the amount of energy is not
