— Never use additional seat cushions that
cover the areas where the side airbags in-
flate.
— Damage to the original 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
replaced with new replacement parts de-
signed and approved especially for your Audi
model version. Replacement of complete
airbag systems or airbag components must
be performed by qualified workshops only.
Make sure that any airbag service action is
entered in your Audi Warranty & Mainte-
nance booklet under AIRBAG REPLACEMENT
RECORD.
— For safety reasons in severe 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
technicians who have the experience, in-
formation and special tools necessary to
perform the work safely.
— If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions
must be followed.

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 control unit. Some suspension changes
can, for example, increase the force levels meas-
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
202
the changes had not been made. Other kinds of
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy-
ing when it should.

Z\ WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in-
crease the risk of serious personal injury in a
crash.
— Never install suspension components that
do not have the same performance charac-
teristics as the components originally instal-
led on your vehicle.
— Never use tire-rim combinations that have
not been approved by Audi.

Knee airbags
Description of knee airbags
The knee airbag system can provide supplemen-
tal protection to properly restrained front seat
occupants.

Fig. 161 Driver's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering wheel > fig. 161, the
airbag for the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and upper and
lower thigh areas and supplements the protec-
tion provided by the safety belts.
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the deployment >

Airbag system

The side airbags installed for the front seating
positions have been designed and certified to
help reduce the risk of injury that can be caused
by airbags when they inflate, particularly when
the occupant sitting next to it is not seated prop-
erly. The side airbag for the front passenger seat
can be used with properly installed child re-
straints. Please be sure to read the important in-
formation and warnings whenever using a child
restraint in a vehicle: Safety belts > page 180,
Airbag system > page 187, Child safety
> page 211.
The side airbag system basically consists of:
— the electronic control module and external side
impact sensors
— the two side airbags located in the sides of the
front backrests
— the airbag warning light in the instrument clus-
ter.
The airbag system is monitored electronically to
make certain that it is functioning properly at all
times. Each time you turn on the ignition, the air-
bag system indicator light will come on for a few
seconds (self diagnostics).
The side airbag system supplements the safety
belts and can help to reduce the risk of injury to
the driver's and front passenger's upper torso on
the side of the vehicle that is struck in a side col-
lision. The airbag deploys in side impacts and on-
ly when the vehicle acceleration registered by the
control unit is high enough. If this rate is below
the reference value programmed into the control
unit, the side airbags will not be triggered, even
though the car may be badly damaged as a result
of the collision. It is not possible to define an air-
bag triggering range that will cover every possi-
ble angle of impact, since the circumstances will
vary considerably between one collision and an-
other. Important factors include, for example,
the nature (hard or soft) of the impacting object,
the angle of impact, vehicle speed, etc.
= page 206, Important safety instructions on
the side airbag system.
Aside from their normal safety function, safety
belts work to help keep the driver or front pas-
senger in position in the event of a side collision
so that the side airbags can provide protection.
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall occu-
pant restraint system in your vehicle. Always re-
member that the side airbag system can only
help to protect you if you are wearing your safety
belt and wearing it properly. This is another rea-
son why you should always wear your safety
belts, not just because the law requires you to do
so > page 180, General notes.
It is important to remember that while the sup-
plemental side airbag system is designed to re-
duce the likelihood of serious injuries, other inju-
ries, for example, swelling, bruising, friction
burns and minor abrasions can also be associated
with deployed side airbags. Remember too, side
airbags will deploy only once and only in certain
kinds of accidents - your safety belts are always
there to offer protection.
Vehicle damage, repair costs or even the lack of
vehicle damage are not necessarily an indication
of over-sensitive or failed airbag activation. In
some collisions, both front and side airbags may
inflate. Remember too, that airbags will deploy
only once and only in certain kinds of collisions -
your safety belts are always there to offer protec-
tion in those accidents in which airbags are not
supposed to deploy or when they have already
deployed.
The side airbag system will not deploy:
— when the ignition is switched off
— in side collisions when the acceleration meas-
ured by the sensor is too low
— in front-end collisions
—in rear-end collisions
—in rollovers.
In some types of accidents the front airbags, side
curtain airbags* and side airbags may be trig-
gered together.

Z\ WARNING
- Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position > page 206.

— Always use the built-in coat hooks only for
lightweight clothing. Never leave any heavy
or sharp-edged objects in the pockets that
may interfere with side airbag deployment
and can cause personal injury in an accident.
— Always prevent the side airbags from being
damaged by heavy objects knocking against
or hitting the sides of the seatbacks.
— The airbag system can only be triggered
once. If the airbag has been triggered, the
system must be replaced by an authorized
Audi dealership.
— Damage (cracks, deep scratches etc.) to the
original seat covers or to the seam in the
area of the side airbag module must always
be repaired immediately by an authorized
Audi dealer.
— If children are seated improperly, their risk
of injury increases in the case of an accident
= page 211, Child safety.

— Never attempt to modify any components of
the airbag system in any way.
—Ina side collision, side airbags will not func-
tion properly if sensors cannot correctly
measure increasing air pressure inside the
doors when air escapes through larger, un-
closed openings in the door panel.
— Never drive with interior door trim panels
removed.

Side curtain airbags
Description of side curtain airbags
Applies to: vehicles with side curtain airbags
The side curtain airbag system can provide sup-
plemental protection to properly restrained oc-
cupants.

Fig. 166 Side curtain airbags, driver's side: side curtain air-
bag location
The side curtain airbags are located on both sides
of the interior above the front and rear side win-
dows > fig. 166. They are identified by the word >

Airbag system

“AIRBAG” on the windshield frame and the cen-
ter roof pillar.
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
interior in certain side impacts and vehicle roll-
overs.
The side curtain airbag system supplements the
safety belts and can help to reduce the risk of in-
jury for occupants’ heads and upper torso. The
side curtain airbag inflates in side impacts and
only when the vehicle acceleration registered by
the control unit is high enough. If this rate is be-
low the reference value programmed into the
control unit, the side curtain airbag will not be
triggered, even though the car may be badly
damaged as a result of the collision. It is not pos-
sible to define an airbag triggering range that
will cover every possible angle of impact, since
the circumstances will vary considerably between
one collision 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 209, How side curtain airbags
work.
Aside from their normal safety function, safety
belts work to help keep the driver or front pas-
senger in position in the event of a collision so
that the side curtain airbags can provide protec-
tion.
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall occu-
pant restraint system in your vehicle. Always re-
member that the airbag system can only help to
protect you if you are wearing your safety belt
and wearing it properly. This is another reason
why you should always wear your safety belts,
not just because the law requires you to do so

It is important to remember that while the side
curtain airbag system is designed to help reduce
the likelihood of serious injuries, other injuries,
for example, swelling, bruising, friction burns
and minor abrasions can also be associated with
these airbags upon deployment. Remember too,

these airbags will deploy only once and only in
certain kinds of accidents - your safety belts are
always there to offer protection.
The side curtain airbag system basically
consists of:
— The electronic control module and external side
impact sensors
— The side curtain airbags above the front and
rear side windows with ejection mitigation fea-
tures
— The airbag indicator light in the instrument
panel
The airbag system is monitored electronically to
make certain it is functioning properly at all

The side curtain airbag is not activated:
— if the ignition is switched off,
— in side collisions when the acceleration meas-
ured by the sensor is too low,
—in rear-end collisions.

Z\ WARNING
— Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position > page 50,
Front seats.
— If the airbag indicator light > page 17
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer. It is possible that
the airbag will inflate when it is not sup-
posed to, or will not inflate when it should.

C) Note
If the engine oil level is too low or too high,
there is a risk of engine damage.
G) Tips
The oil level indicator in the display is only an
informational display. If the oil level is too
low, a minimum oil warning appears in the in-
strument cluster. Add oil and close the engine
compartment lid. The current oil level is dis-
played in the Infotainment system the next
time the ignition is switched on.
G) Tips
— The engine oil consumption may be up to
1 quart per 600 miles (0.8 liter/1,000 km),
depending on driving style and operating
conditions. Consumption may be higher dur-
ing the first 3,000 miles (5,000 km). The
engine oil level must be checked regularly.
It is best to check each time you refuel your
vehicle and before long drives.
— Because of the lubrication and cooling of
the engine, combustion engines consume
oil. The oil consumption varies depending
on the engine and may change during the
service life of the engine. Engines generally
consume more oil at the beginning during
the break-in period. Then oil consumption
stabilizes after the break-in period.
— Under normal conditions, oil consumption
depends on the quality and viscosity of the
oil, the engine RPM, the climate conditions,
and the road conditions. The dilution of oil
from condensation or fuel residue as well as
the age of the oil also play a role. Because
engine wear increases with mileage, oil con-
sumption will increase again over time until
it may be necessary to replace worn compo-
nents.
— Because all these variables play a role, it is
not possible to define an oil consumption
standard. Therefore, the oil level must be
checked regularly.

AN WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla-
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.

ZA\ WARNING
Temperature grades apply to tires that are
properly inflated and not over or underinflat-
ed.

Tire pressure monitoring
system
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat-
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la-
bel, you should determine the proper tire infla-
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS)
that illuminates a low tire pressure tell-
tale when one or more of your tires is significant-
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving ona signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop-
ping ability.
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.
Applies to: vehicles with tire pressure monitoring system
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
The 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.
The tire pressure monitoring system shows the
current pressures and temperatures of the tires
in the Infotainment system while driving
=> page 262. 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 262.
The system does not detect if the stored tire
pressures match the recommended tire pres-
sures. You must store the tire pressures again in
each of the following situations > page 263:
— Each time the tire pressures change, for exam-
ple when the load in the vehicle changes
— After replacing a tire
261

Wheels

— If wheels with new wheel sensors are used

Z\ 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, increas-
ing 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 accident.
— 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.

G) Tips
—If tires are replaced, the sensors and valves
do not need to be removed or replaced. Only
replace 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 authorized Audi Service Facility.

FCC regulations in the United States and the
Industry Canada regulations, see
