Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide
supplemental protection to properly restrain ­
ed occupants.
Fig . 164 Side c urtain airbags, dri ver 's side: s ide curta in
a irb ag location
The side curtain airbags are located on both
sides of the interior above the front and rear
side windows
c:.> fig. 164. They are identified
by the word "AIRBAG" on the windshield
frame and the center roof pi llar.
The s ide curtain airbag system supplements
the safety belts and can help to reduce the risk of injury for occupants' heads and upper
torso on the side of the vehicle that is struck in
a side collision. The side curtain airbag in­
flates in side impacts and only when the vehi­
cle acceleration registered by the control unit
is high enough . If this rate is below the refer­
ence value programmed into the control unit,
the side airbags will not be triggered, even
though the car may be badly damaged as a re­ su lt of the collision .
It is not possib le to de­
fine an airbag triggering range that will cover every possible angle of impact, since the cir­
cumstances will vary considerably 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 169, 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
s ion so that the side curtain airbags can pro­
vide protection .
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall oc­
cupant restraint system in your vehicle. Al­
ways remember that the airbag system can
only help to protect you if you are wear ing
your safety belt and wearing it properly . This
is another reason why you should always wear
your safety belts, not just because the law re­
quires you to do soc:.>
page 136, General
notes .
It is important to remember that wh ile the
s ide curtain airbag system is designed to help
reduce the likelihood of serious injuries, other
injuries, for example, swelling, bruising, fric­
tion burns and minor abrasions can also be as­
sociated with these airbags 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 offer pro ­
tection.
The side curtain airbag system basically
consists of:
- The electronic control module and external
side impact sensors ..,..

190 Audi pre sense
Audi pre sense
Preventative passenger
protection
A pp lies to veh icles: with Audi pre se nse
Audi pre sense can initiate steps to help pro­
tect vehicle occupants in certain situations.
The functions described depend on equ ipment
installed in your vehicle:
Audi pre sense basic*
The following functions can be triggered in
certain 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 Aud i 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 c::>poge
88
-Tightening the safety be lts
- 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 collision with the vehicle
coming from behind is also calcu lated.
If the risk
of a co llision is detected, the following
functions can be triggered:
- Tig htening the safety belts
- Closing the windows and the sunroof* (leav-
ing a small open gap)
Audi pre sense plus*
Audi pre sense plus includes the functions 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.
_& 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 r isk of a collis ion and serious personal
in juries .
- The sensors cannot always detect all ob­
jects. This increases the risk of a colli­
s10n.
-Aud i pre sense does not detect people or
an im als or objects that are crossing the
veh icle's path c::> page
82.
-The radar sensor's vis ion can be reduced
by heavy rain, ice, snow, heavy road sp ray
and reflections from guard rails, tunnel
entrances, etc. These and similar condi­
tions can prevent vehicles from being ac ­
curately detected and in some cases they
may not be detected at all.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the function of
the Audi pre sense system. Have your au­
thorized Audi dealer check to make sure
that the system is working properly.
