Fig. 161 Side curta in airbags, driver's side: s ide curtain air­
bag locat ion
The side curtain airbags are located on both sides
of the interior above the front and rear side win­
dows
Q fig . 161. They are identified by the word
"AIRBAG" on the windshield frame.
The side curtain airbags contain features that provide ejection mitigation to help prevent vehi­
cle occupants or parts of their bodies from being
completely or partially ejected from the vehicle
inter ior in certain side impacts and veh icle roll-
overs.

Airbag system
The s ide curtain airbag system supp lements the
safety belts and can he lp to reduce the risk of in­
jury for occupants' heads and upper to rso . The
side curtain airbag inflates in s ide impacts and
only when the veh icle acce leration registered by
the co ntro l unit is h igh eno ugh . If this rate is be ­
low the refe re n ce value programmed in to the
con trol unit, the s ide curta in a irbag will no t be
tr iggered, even though the ca r may be bad ly
d a mage d as a r esult of the collis io n.
It is not pos­
sib le to def ine an a irbag tr iggering range that
will cover every possib le ang le o f impact, since
the circumstances will vary considerably between
one co llision and another. Important factors in­
clude, for example, the nature ( hard or soft) of
the impacting object , the angle of impact, vehicle
speed, etc.
¢ page 168, How side curtain air­
bags work .
Aside from their normal safety function, safety
be lts work to help keep the driver or front pas­
senger in pos it io n in the event of a collision so
that t he side curtai n airbags can provide protec ­
tion .
The a irbag system is not a substitute for your
safety belt . Rathe r, it is part of the overa ll occu ­
pant restrain t system i n your veh icle . Always re­
membe r th at th e airbag system can only help to
p rotect yo u if you a re we aring your safety bel t
and wearing it pro perly . T hi s is anothe r reason
why you should always we ar your s afety belts,
not just because the law requires you to do so
¢ page 138, General information .
It is import ant to remember th at whi le t he s ide
curt ain ai rbag system is des igned to help reduce
the likelihoo d of serious injur ies, other injuries,
for example, swe lling, b ruising, friction burns
and minor abrasions can also be assoc iated with
these airbags upon deployment . Remember too,
these airbags will deploy only once and only in
certa in kinds of acc idents

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
¢page 226. It also
compares the current tire pressures with the
stored tire pressures and gives a warning in the
driver information system if the tire pressure is
different from what is
stored ¢ page 226 .
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 226:
- 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
