• For security reasons, replacement keys are only available from
Audi dealers. •
Master key with remote control
The remote control allows you to lock or unlock the
vehicle electronically.
Fig. 24 Fold-up
master key with
remote control
-To fold the key out and back in place, press the release
button~ fig. 24.
The transmitter and battery are located in the head of the remote
control. The receiver is located inside the vehicle. The maximum
effective range depends on several things . Remember, if the battery
is weak, the effective range decreases.
If you need to replace the remote contro l, or if you need to have it
repaired, you must see your authorized Audi dealer. Only then can you
use the key again.
Personalizing the master key
When the ignition is turned off or when the veh icle is locked, various
convenience settings are stored automatically and assigned to the
key that was used. The settings that are ass igned to the master key
are recalled automatically when the vehicle is un locked, when the
door is opened o r when the ignition is sw itched on. Settings are saved for the following systems:
•
Climate control
• Central locking
• Ambient lighting
• Windows
• Park ing System*
• Seat memory*
The
Remote control key function must be activated in the MMI
=> page 80, so that the settings for the driver's seat (including the
sett ings for the steering column and exterior mirrors) a re saved on
the master key through the seat memory when the vehicle is locked,
and are set automat ically when the vehicle is unlocked.
[ i ] Tips
• If the ignit ion is switched on, the remote control system is deacti­
vated.
• The remote control system can be affected by other systems oper­
ating in the same frequency range close to the vehicle, such as mobile
telephones, telev isio n broadcasting s tations, etc.

Safety tips
T he s ide assist detection may be limited w hen driving aro und narrow
str eet co rn ers, on hill y stree ts, and under p oor we ath er co nditions . It is possib
le that the radar senso rs may also detect other objects,
such a s high or st agg ere d gu ardr ails.
Side assis t does not measure ac tual lane wid th . T he sys tem assumes
a fixe d lane w idth . Detection in the le ft and rig ht lanes is based on
th is ass um ed lan e width . Wh en drivi ng on narrow ro ads or w hen
driv ing to t he left or r ight of t he cente r of a t ravel lane, it is possib le
that vehicles will be de te ct ed th at are
no t in th e lan e nex t to th e lane
you a re us ing.
& WARNING
• Improper reliance on the side assist system can cause collisions
and serious personal injury:
-Never rely only on side assist when changing lanes.
- Always check rear view mirrors to make sure that it is safe to
change lanes.
• Side assist cannot detect all vehicles under all conditions­
danger of accident!
• Side assist cannot detect vehicles in time to alert you when
they approach from behind at very high speed , or fall drop back
very quickly.
• The radar sensor's
vision can be reduced or entirely blocked by
rain, snow, and heavy spray. This can result in side assist not
adequately detecting vehicles or, in some cases, not detecting
them at all . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle .
• Please note that side assist indicates there are approaching
vehicles, or vehicles in your blind spot , only after your vehicle has
reached a driving speed of at least 19 mph (30 km/h).
• Side assist signal does not work around tight corners (turning
radius less than 328 feet, or 100 m) .
• Side assist is no replacement for the driver's full attention . The
driver alone is responsible for lane changes and similar driving
maneuvers. Always keep an eye on the direction you are traveling
and the relevant area around the vehicle.

& WARNING (conti nued)
• Always make sure that the side a irbag can inflate without
interference :
- Never in stall seat covers or replacement uphol stery over the
front seatbacks that have not been specifically approved by
Audi .
- Never use addit ional se at cushions that cover the areas
where the side ai rbags inflate.
- Damage to the or iginal seat covers or to the seam in the area
of the side airbag module must always be repaired immedi­
ately by an author ized Audi dealer.
• The airbag system can be activated only on ce. After an airbag
has inflated, it must be replaced by an authorized Audi dealer or
qualified technician who has the techni cal information, t raining
and special equipment necessary.
• The airbag sy stem can be deploy ed only once. After an airbag
has been dep loyed , it must be replaced with new replacement
parts designed and approved e specially for your Audi model
version. Replacement of complete airbag systems or a irbag
components must be performed by qualified workshops onl y.
Make sure that any airbag service action is entered in your Audi
Warranty
& Maintenance booklet under AIRBAG REPLACEMENT
RECORD .
• For s afety reason s in s evere accidents, the alternator and
starter are separated from the vehicle battery with a pyrotechnic
circuit interrupter.
-Work on the pyrotechnic circuit interrupter must only be
performed by a qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter is sc rapped , all appli ­
cable safety precautions must be followed.

tions must be observed. Yo ur authorized Aud i dealer is familiar w ith
t hese requi reme nts and we recommend tha t yo u have yo ur dealer
perform th is service for you. •
Other things that can affect Advanced
Airbag performance
Chang ing the vehicle's suspension system can change the way that
t h e Advan ced Airbag System pe rforms in a cr ash . For e xamp le, usi ng
tire-rim combinations not app roved by Audi, lowering the vehicle,
c hang ing the stiffness o f th e suspension, incl uding the sp rings,
suspension struts, shock absorbers etc. can change the forces that
are meas ured by the a irbag sensors and sent to the ele ct ronic contro l
unit . Some suspension changes can, fo r exam ple, increase the force
levels measured by the senso rs and make the airbag system deploy in
crashes in which i t would not deploy if the changes had no t been
ma de . Other kinds of changes may reduce the force levels meas ured
by the sensors and p revent the airbag from dep loying when it should.
T he sensors in the safety belt b uckle for the drive r and front
p as senge r se at tell the e lectroni c cont rol mo dule if the sa fe ty belt is
latched or not . If the safety belt is being used, t he front a irbag w ill
dep loy a t a s lightly h igher r ate o f vehicle decele ration t han if t he
safety belt is not be ing used . Therefo re, in a par ticular collis io n, it is
possible that an a irba g w ill not dep loy at a seating position where the
safety belt is being used but w ill inflate at the posit ion where the
safety belt is not be ing use d. It is im portant that nothing interfere
w it h t he safety belt bu ckles so that t he sensors can se nd the co rrect
info rmation about safety be lt use to the electronic contro l unit.

Battery replacement
The new battery must have the same specifications and
dimensions as the original equipment battery.
Inte lligent energy management in your veh icle is responsible for
dis trib uti ng the elect ric al ene rgy throughout yo ur vehi cle
::} page 249. The intelligent energy management system will keep
t he e ngine battery charged be tter then vehicles withou t this system.
To make sure the additional e lectrical energy is available once again
after you have changed the ba tte ry, we recom mend that you in sta ll
batter ies of the same type and manufacture only (the same as those
installed at the t ime your vehicle was delivered). Specifications are
listed on the battery hous ing. You r authorized dealer must code the
battery in t he energy ma nageme nt system to enab le yo u to use the
energy management functions corre ct ly aft er replac ing the battery.
If it is not poss ible to use a battery of this type, the new battery must
have the same capacity, vo ltage ( 12 volts), ampe rage, co nstr uction
and plug sea ling.
When install ing the battery, make sure the ign it ion and a ll electrica l
c ons umers are tur ned off.
