Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide
supplemental protection to properly restrain
ed occupants.
Fi g. 1 73 Side curtain a irbags, d river 's side: s ide curta in
a ir bag location
The s ide curtain airbags are located o n both
sides of the interior above the front and rea r
side windows
c:.> fig. 173 . They are ident ified
by the word "AIRBAG" on the windshield
frame and the center roof p illar.
The s ide curtain airbag system supp lements
the safety belts and can help to reduce the risk of injury for occupants' heads and upper
torso o n the side of the vehicle tha t is struc k in a side collision
. The side curtain airbag in
flates in side impacts and only when the vehi cle acceleration registered by the control un it
is h igh enough . If this rate is below the refer
ence value programmed into the control unit,
the side airbags will not be triggered, even
t h ough the car may be bad ly damaged as a re
su lt of the co llision .
It is not possib le to de
fine an airbag triggering range that will cover every possib le ang le of impact, s ince the cir
cumstances will vary cons iderably between
one collision and another. Important factors
include, for example, the nature (hard or soft)
of the impacting object, the angle of impact,
vehicle speed, etc .
c:,, page 175, How side cur
tain airbags work .
Aside from their normal safety function, safe
ty belts work to help keep the driver or front
passenger in position in the event of a colli
sion so that the side curtain airbags can pro
vide protection .
The airbag system is not a substit ute for your
safety belt . Rather, it is part of the overall oc
cupant restraint system in your vehicle. Al
ways remember that the a irbag system can
only help to protect you if you are wear ing
you r saf ety belt and wearing it properly . This
is anothe r reason why yo u should always wear
yo ur safe ty belts, no t just because the law re
quires yo u to do soc:.>
page 145, General
notes .
It is important to remember that w hile the
s ide cur tain airbag system is designed to help
reduce the likelihood of ser ious injur ies, other
injuries, for example, swelling, bruising, and
minor ab rasions can also be associated with
these a irbags upon dep loyment. Remember
too, these airbags will deploy only once and
only in certain kinds of accidents -your safety
belts are always there to offe r protection .
The s ide curtain a irbag system basic ally
cons ists of:
- The e lectronic control module and external
side impact sensors
- The side curtain airbags above the front and
rear s ide windows
Audi pre sense Preventative passenger
protection
App lies to veh icles: with Audi p re se nse
Audi pre sen se can ini tiate steps to help pro
t ect vehicle occupants in certain situations.
The funct ions descr ibed depend on equipment
installed in your vehicle:
Audi pre sense basic
The following functions can be triggered in
cert ain driving situations :
- Tightening of the safety belts (for example,
during heavy braking) : the front safety belts
have reversible belt pretensioners. If a colli
sion does not occur, the safety belts loosen
slightly and are ready to be tightened again .
- Closing the windows and the sunroof* : the
windows and the sunroof" close leaving a
small open gap .
Audi pre sense basic functions can be trig
gered at speeds above 20 mph (30 km/h) .
Vehicles with Audi drive select*: the deploy
ment time is adapted in dynamic mode.
Audi pre sense front (vehicles with
adaptive cruise control*)
Audi pre sense front includes the functions in
Audi pre sense basic. In addition, within the
limits of the system, the likelihood of a colli
sion with the vehicle immediately ahead is al
so calculated . If the system senses an immi
nent collision the following functions can be
tr iggered:
- Braking guard
¢ page 100
-Tightening the safety belts
- Closing the windows and the sunroof* ( leav-
ing a small open gap)
Audi pre sense rear (vehicles with Audi
side assist*)
Audi pre sense rear includes the functions in
Audi pre sense basic. In addition, the likeli
hood of a rear-end col lision with the vehicle
coming from behind is also calculated. If the
Audi pre sense 197
risk of a collision is detected, the following
functions can be triggered :
- Tightening the safety belts
- Closing the windows and the sunroof* (leav-
ing a small open gap)
- Adjusting the seats: the settings for the
power head restrains, the upper sections of
the backrests and the pneumatic side bol
sters* are optim ized for the front seats and
the outboard rear seats*. If a collision does
not occur, the previous seat settings are re
stored.
Audi pre sense plus
Audi pre sense plus includes the funct ions in
Audi pre sense front and Audi pre sense rear.
Error message
Audi pre sense: not available
Preventative passenger protection is not avail
able. See your authorized Audi dealer immedi
ately to have the malfunction corrected .
A WARNING
Audi pre sense cannot overcome the laws
of physics.
It cannot prevent a collision. Do
not let the increased safety provided
tempt you to take risks. This will increase
the risk of a collision and serious personal
injuries.
- The sensors cannot always detect all ob
jects . This increases the risk of a colli
sion.
-Audi pre sense does not detect people or
animals or objects that are crossing the
veh icle's path ¢
page 94.
- The radar sensor's vision can be reduced
by heavy rain, ice, snow, heavy road spray
and reflections from guard rails, tunnel
entrances, etc. These and similar condi
tions can prevent vehicles from be ing ac
curately detected and in some cases they
may not be detected at all.

A WARNING
-
A hood that is not completely latched
could fly up and b lock your view while dr iv

-When you close the engine hood, check it
to make sure the safety catch has p roper
ly engaged. The hood sho uld be flush
with the surrou nding vehicle body pa rts.
- If you notice while driv ing t hat the hood
is not s ecured prope rly, stop at onc e and
close it.
(D Tips
The oil level indicator in the MMI Display is
only an information d isp lay. If the oil leve l
is low, a minimum oi l warning appears in
the instrument cluster. Add oil

Determining th e oil le ve l
.. Park your vehicle on a level surface.
.. Let the engine run in idle briefly while it is at
operating temperature and then shut the
engine off .
.. Wait approximately two minutes .
.. Remove the oil dips tick. W ipe off the oil dip
stick with a clean cloth and insert it all the
way in again.
.. Remove the dipstick again and then read the
oil level

checked regularly.
It would be best to check
each time you refuel your vehicle and before
