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.
Number of keys
You can check the number of keys ass igned to
your vehicle in the Infotainment system . To do
this, select the
I MENU 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 immobilizer prevents unautho rized use of
the vehicle .
Unde r certain circumstances, the vehicle may not
be able to start if there is a remote contro l key
from a different vehicle manufacturer on the key
chain .
Data in the master key
When driving , service and maintenance- relevant
data is continuously stored in your remote con­
trol key . Your Audi service adviso r can read out
this data and te ll you about the work your vehicle
needs. This applies also to veh icles 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 ignition is turned
off or when the
ve hicle is locked, persona l convenience settings
for the following systems are stored and as­
signed to the remote master key .
- Climate control system
- Parking aid*
- Active lane assist*
- Side ass ist*
- Drive select

Opening and closing
A WARNING
If you leave the vehicle, switch the ignition off
and take the vehicle key w ith you. This applies
particularly when children remain in the vehi­
cle . Otherwise the child ren cou ld start the en­
g ine or operate electrical equ ipment such as
power windows.
(D Note
Protect the remote control key against high
temperatures and direct sunl ight.
(D 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
yo ur vehicle is locked!

Avoid full acceler ation
You sho uld rare ly t rave l a t t he maxim um vehicle
speed . High speeds cause a disproportionately
h igh increase in fuel consumption, emissions and
traffic noise . Slower driving saves fuel.
Reduce idling time
It pays off to stop the eng ine, for example when
at ra ilroad crossings or traffi c lights w ith longer
red lights . Stopping the engine for 30 -40 sec­
onds already saves more fuel than the amount of
extra fuel needed to restart the engine.
I t takes a very long time in idle to wa rm the en­
gine up to operating tempera ture . Wea r and
emissions are especially high in the warm -up
p hase . Therefore, you should begin driving im ­
mediately after starting the engine. Avoid high
RPMs while do ing th is.
Hav e ma intenanc e performed r egularly
By having maintenance performed regu lar ly on
your vehicle, you can he lp to reduce fuel con ­
sumption before yo u even start to drive. The
maintenance condition of your vehicle not only
affects traffic safety and long-term va lue but al­
so impacts
fu el con sumpt ion .
A poorly maintained engine can lead to fuel con ­
sumpt ion that is 10% higher than norma l.
A lso check the
o il l evel when refueling . The oil
consumpt ion
depends large ly on the engine load
and speed. It is normal for the oil consumption
of a new eng ine to reach its lowest point only af­
ter a certain amount of use. Therefore, the oil
consumption can only be properly judged after
approx imately 3,000 m i (S,000 km) have been
driven.
Avoid short trips
The engine and exhaust clean ing system must
reach their opt imal
op erating temp eratur e to ef­
fective ly reduce consumpt ion and emiss ions.
A co ld engine uses a disproportionately h igh
amount of fuel. The eng ine reaches operating
temperature and consumpt ion normalizes only
afte r approx imately
2.5 miles (4 km) .
Driving
@ Note
Do not leave engine idling unattended after
start ing. If warning lights sho uld come on to
i ndicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could resu lt in overheating or
other damage to the veh icle o r other proper­
ty.
@ Note
- Have your ve hicle ma intained properly and
in accordance w ith the service recommenda­
tions i n your Warranty
& Main tenance book­
let. La ck of prope r mai nte nan ce as we ll as
imp rope r use of t he ve hicle will impa ir the
function of the em iss ion cont ro l system and
co uld lead to damage .
- Do not alte r or remove any compone nt o f
t he Emission Contro l System unless ap ­
proved by the man ufacturer .
- Do not alte r or remove any dev ice, s uch as
heat shields, switc hes, ignition wires,
valves, which are designed to protect your
vehicle's Emission Contro l System and other
impo rtant ve hicle components.
(D Tips
The cons umption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and T ransport Canada may not co rre­
spond to your actual consumption on the r oad, wh ich w ill vary depending upon veh icle
l oad and speed, road and weather cond itions,

-Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
Aud i.
- Never use add itiona l seat cushions that
cover the areas where the s ide airbags in­
flate.
- Damage to the origina l seat covers or to
the seam in the area of the side airbag module must always be repaired immedi­
ately by an authorized Audi dealer.
- The airbag system can deploy only once . Af­
ter an airbag has been deployed, it must be
rep laced with new rep lacement parts de­
signed and approved especially fo r you r
Audi mode l version. Replacement of com­
plete airbag systems or airbag components
must be performed by qualified workshops
only . Make sure that any airbag service ac­
tion is entered in your Audi Warranty

Airbag syste m
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash. For example, using tire-rim
combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension, including the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic cont rol u nit. Some suspension c hanges
can, for example, increase the fo rce leve ls meas­
u red by the sensors and make t he a irbag system
deploy in crashes in which it wou ld not deploy if
the changes had not been made. Other kinds of
changes may reduce the force levels measured by
the sensors and prevent the a irbag from deploy­
ing when it should.
A WARNING
-
Changing the vehicle's suspension including use of unapproved tire-rim combinations can
change Advanced Airbag perfo rmance and in­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
ter istics as the components o riginally instal­
led on your vehicle .
-Never use tire-rim combin ations that have
not been approved by Audi .

Tire pressure monitoring system
(J_) General notes
Each tire, incl uding the spare (if provided),
should be checked month ly when co ld and inflat­
ed to the inf lation pressure recommended by the
ve hicle manufacturer on the vehicle placard or
tire inflat ion pressure label. (If your vehicle has
tires of a d ifferent s ize tha n the s ize indicated on
the veh icle placa rd or t ire inflation pressure la­
be l, you s hou ld determine the prope r tir e infla­
tion pressure fo r th ose tires).
As an added safety feature, your ve hicle has been
equ ipped w ith a t ire pressu re monito ring system
(TPMS) that ill uminates a low tire p ress ure tell­
tale whe n one or more of yo ur t ires is sign ificant ­
l y unde r-infla ted. Accord ingly, whe n the low tire
p ressure tellta le illuminates, yo u should stop and
check your tires as soon as possible, and inflate
them to the proper press ure. D riving on a signifi ­
cantly under-inflated tire causes the tire to ove r­
h eat and can lead to t ire failure. Under-inflation
a lso reduces fuel efficiency and ti re tread life,
and may affect the veh icle's handling and stop­
p ing ability .
P lease note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsib il ity to ma inta in correct tire pressure,
even if u nder-inflation has not reached t he leve l
to tr igger illum inat io n of t he TPM S low tire p res ­
sure telltale.
Your veh icle has also been equ ipped w ith a TPMS
malfunct ion ind icator to indicate when the sys­
tem is not operat ing properly. The TPMS ma l­
f u nction ind icator is combined w ith the low tire
p ressure tellta le. Whe n the system det ects a
mal function, the te lltale wi ll flash fo r approxi ­
mate ly one mi nute and then remain continuous ly
illum inated. This sequence will continue upon
subseq uent ve hicle start-ups as long as the ma l­
function ex ists .
W hen t he malfunctio n indicator is ill uminated,
the system may not be ab le to detect or signa l
low t ire press ure as intended. TPMS ma lfunctions
may occur for a var iety of reasons, including the
Wheels
insta llation o f replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning p roperly . Always check the
TPMS ma lfunction te lltale after replac ing one or
more tires or wheels on you r vehicle to ensure
t h at the rep lacement or a lternate tires a nd
wheels allow t he TPMS to continue to function
prope rly.
If the Tire Pressure Monitoring System
indicator appears
Applies to: vehicles with Tire Pressure Monitoring System in­
dicator
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
U sing the ABS se nsors, the t ire pressure monitor­
ing system compares the tire tread c ircumfer­
ence and v ibration characterist ics of the ind ividu­
al tires. If the pressu re changes in one o r more
t ir es, th is is indica ted in the Info tainment sys tem
display wi th an indica to r li ght
ti] and a message.
If only one ti re is affected, the location of tha t
tire will be indicated.
T he tire press ures mus t be store d in the Infota in­
me nt system agai n ea ch t ime t he p ressures
change (switching between partia l and full load
pressure) or after c hanging or replacing a tire on
yo ur vehicle

toring system on ly monitors the tire pressure you
have stored. Refer to the t ire pressure label for

Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale .
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly . Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Description
Applies to: vehicles with tire pressure monitor ing system
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
T he system uses sensors that measure the tem ­
perature and pressure in the tires . The data is
sent from these sensors to the control module by radio frequency.
T he tire pressure monitoring system shows the
current pressures and temperatures of the tires
in the Infotainment system while driving
¢ page 264. It also compares the current tire
pressures with the stored tire pressures and
gives a warning if the tire pressure is different
from what is stored
¢ page 264 .
Wheels
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures. You must store the tire pressures again
¢ page 264:
- every time the tire pressures change, for exam­
ple when the load in the vehicle changes,
- after replacing a tire, or
- if wheels with new wheel sensors are used.
_& WARNING
- The tire pressure monitoring system assists
the driver in monitoring tire pressures. The
driver is responsible for having the tires in­
flated to the correct pressure.
- Do not change the tire pressure when the
temperature of the tire is extremely high.
This could result in serious damage to the
tire and even cause the tire to burst, in­
creasing the risk of an accident.
- A tire with low pressure flexes more. This heats the tire up too much. This could cause
the tread to separate and even cause the
tire to burst, increasing the risk of an acci­
dent.
- The tire pressure monitoring system does not warn about damage or defects in the
tire construction that could cause the tire to
burst, for example. Inspect your tires regu­
larly.
(D Tips
- If tires are replaced, the sensors/valves do
not need to be removed or replaced . Just re­
placed the valve stem and, if necessary, the
valve and the wheel electronics. If you have questions, see an authorized Audi dealer or
authorized Audi Service Facility.
- An incorrect display or a malfunction in the
tire pressure monitoring system can occur
after using the tire mobility kit. Have the
sensors replaced by an authorized Audi
dealer or authori zed Audi Service Facility.
- For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see
