— Push the lever upward firmly so that the
steering wheel position does not change un-
intentionally while driving, which would in-

crease the risk of an accident.

Head restraints
General information
Applies to: vehicles with adjustable head restraints

B4G-0454



Fig. 60 Correctly adjusted head restraints
Make sure that:
— The upper edge of the head restraint is as even
as possible with the top of your head
— The head restraint is as close as possible to the
back of the head
— The head restraints in any occupied rear seats
are all the way up

Z\ WARNING
— There is one head restraint for each seating
position. All vehicle occupants must adjust
the head restraint correctly before every
trip. Having head restraints that are not ad-
justed correctly or not installed in the vehi-
cle increases the risk of a neck injury during
sudden or unexpected driving or braking
maneuvers or in a collision.
— Only remove the rear seat head restraints if
it is necessary to install a child safety seat
=> page 72. Stow the removed head re-
straints securely, for example in the luggage
compartment. Reinstall the head restraints
immediately once the child safety seat has
been removed. Driving without head re-
straints increases the risk of serious neck in-
juries.

Safety belts
Each seat is equipped with a three-point safety
belt. Safety belts that are worn correctly are the
most effective way to reduce the risk of serious or
fatal injuries in a collision. Therefore, wear your
safety belt correctly and make sure that all vehi-
cle passengers are also wearing their safety belts
correctly when the vehicle is moving.
Even though your vehicle is equipped with an air-
bag system, every vehicle passenger must still al-
ways wear the appropriate safety belt. In addi-
tion to their normal protective function, safety
belts also hold vehicle occupants in the correct
seating position in the event of a collision so that
the airbags can deploy correctly and provide addi-
tional protection. Safety belts provide protection
during collisions when the airbags do not deploy
or if they have already deployed.

Z\ WARNING
The risk of serious or fatal injury increases if
the safety belt is not fastened, if it is worn in-
correctly, or if it is damaged.
— All vehicle occupants, including the driver,
must fasten their safety belts correctly be-
fore every trip and must always keep their
safety belts fastened during the trip, regard-
less of whether the seat is equipped with an
airbag or not. This also applies to children

64


that are seated in a child safety seat that is
appropriate for their weight and age and
that is secured with a safety belt.
In the event of a collision, vehicle occupants
that are not wearing safety belts could be
propelled through the vehicle interior and
collide with vehicle components, such as the
steering wheel, instrument panel, wind-
shield, or doors. In some situations, vehicle
occupants could also be ejected from the ve-
hicle. Vehicle occupants in the rear seats
who do not wear safety belts not only en-
danger themselves, but also other people in
the vehicle.
Only one person may be fastened with a
safety belt at a time. Never secure more
than one person, including children, with a
single safety belt.
Never allow children or infants to ride on an-
other person's lap and be belted into the
safety belt with them.
Insert the belt buckle only in the belt latch
belonging to the corresponding seat, so that
the protective function is not impaired.
To ensure the maximum protective function
of the safety belts, all vehicle passengers
must sit in the correct seating position
=> page 59.
Check the condition of your vehicle’s safety
belts regularly > page 248. If you find dam-
age to the belt webbing, the belt connec-
tions, the retractor, or the buckle, have the
damaged safety belt replaced by an author-
ized Audi dealer or authorized Audi Service
Facility.
The safety belts must not be removed or
modified in any way. Do not attempt to re-
pair the safety belts yourself.
Safety belts that are strained during an acci-
dent, and thus stretched, must be replaced
by an authorized Audi dealer or authorized
Audi Service Facility.

safety belt is not fastened or it has been unfas-
66

tened while the vehicle is in motion. Above cer-
tain speeds, additional warning tones will sound.
Belt retractor lock
The safety belts on the rear seats and on the
front passenger seat are equipped with a belt re-
tractor lock.
— If you secure a child safety seat with a safety
belt, the belt retractor lock on the safety belt
may need to be activated. Follow the instruc-
tions from the child safety seat manufacturer.
— When a vehicle passenger has fastened a safety
belt, the belt retractor lock should not be acti-
vated. If the belt retractor lock has been acti-
vated unexpectedly, deactivate it.

Sitting correctly and safely


you. This increases the risk of serious or fa-
tal injuries. Make sure that every vehicle
passenger has their safety belt correctly fas-
tened and is sitting in a correct seating posi-
tion > page 59. This is necessary regardless
of whether the seat is equipped with an air-
bag or not.
— Never place your feet on the instrument
panel, out of the window, or on the seat sur-
faces. To help ensure that the airbag system
can deploy correctly, never bend forward or
lean on the door or the side window. Other-
wise, serious and possibly fatal injuries can
occur if the airbags deploy.
— People, animals, or objects between the
Passengers and the airbag system can inter-
fere with the correct deployment of the air-
bag or can be thrown through the vehicle in-
terior, increasing the risk of serious or fatal
injuries. Make sure that nothing is located
between the vehicle occupants and the air-
bag system. Do not secure or transport any
objects within the deployment zone of the
airbag systems, especially on the steering
wheel, on the instrument panel, on the
doors, on the windows, or in the footwell.
— Never put stickers on the airbag system cov-
ers or cover them with any objects.
— Only lightweight clothing should be hung
from the garment hooks in the vehicle. Do
not use clothes hangers to hang clothing.
The pockets of the clothing must not con-
tain any heavy, breakable, or sharp-edged
objects. This could impair the effectiveness
of the side curtain airbags.
— You must not use seat or protective covers
that are not specifically approved for use on
Audi seats with side airbags. Since the side
airbags deploy from the seat backrest, such
covers could impair the protective function
of the side airbags.
— Damage to the original seat covers in the
side airbag deployment area must always be
repaired by an authorized Audi dealer or au-
thorized Audi Service Facility.
— Airbag system components are installed at
various locations in your vehicle. Incorrect
work or repairs on the vehicle could damage

68
the airbag system components or impair
their functionality. This may prevent the air-
bags from deploying or cause them to de-
ploy incorrectly in the event of an accident,
which increases the risk of serious or fatal
injuries. Only have an authorized Audi dealer
or authorized Audi Service Facility make re-
pairs or modifications to a vehicle.
— The airbag system can only provide protec-
tion during one collision. If there is another
collision, the airbag system will not deploy
again. If the airbag system has deployed,
have it replaced immediately by an author-
ized Audi dealer or authorized Audi Service
Facility.
— Fine dust may appear if the airbags deploy.
This is completely normal and does not indi-
cate a fire in the vehicle. The fine dust can ir-
ritate the skin and mucous membranes in
the eyes and can cause difficulty breathing,
particularly for individuals who have or have
had asthma or other health issues that af-
fect breathing. Exit the vehicle or open the
windows or doors to get access to fresh air.
G) Tips
If you are transporting children in the vehicle,
read the information and follow the safety
precautions > page 72.
Safety systems monitoring
The ka indicator light in the instrument cluster
monitors the safety systems such as the airbags
(including the control modules, sensors, and wir-
ing) and the belt tensioners. It turns on when you
switch the ignition on and turns off after several
seconds.

If the ka indicator light does not turn on when
the ignition is switched on, does not turn off af-
ter several seconds, or turns on or flashes while
driving, there may be a malfunction in one of the
safety systems. Drive to an authorized Audi deal-
er or authorized Audi Service Facility immediately
to have the malfunction corrected.

Sitting correctly and safely

may be severely damaged from the accident. In
these cases, the vehicle occupants will be pro-
tected by the safety belts if they are fastened and
worn correctly.
The deployment of the front passenger's airbag
will depend on the occupancy of the seat
=> page 70.
Each deployed airbag is filled with gas. When this
occurs, the airbag covers open and the airbags
unfold with great force into the deployment zone
within milliseconds. Inflated airbags reduce the
movement of passengers wearing safety belts in
the direction of the impact and thus help to re-
duce the risk of injury. They can help to protect
the head, upper body, and lap, for example. How-
ever, there is the possibility that airbag deploy-
ment can cause injuries.
The airbag system only works when the ignition
is turned on.
If you or other vehicle passengers have physical
limitations that prevent sitting in a correct posi-
tion, modifications to the vehicle may be neces-
sary. For more information, contact an author-
ized Audi dealer or authorized Audi Service Facili-
ty, or call Audi customer support at
1-800-822-2834.
@ Tips
The side curtain airbags in your vehicle have
ejection mitigation functions. This reduces
the risk of being ejected from the vehicle inte-
rior during an accident, especially in the event
of a vehicle rollover.
Advanced a ea)

Fig. 69 Headliner: indicator light to display the status of
the front passenger's airbag
70
The Advanced Airbag System in your vehicle has
been certified to comply with the requirements
of the United States Federal Motor Vehicle Safety
Standard (FMVSS) 208, as well as Canada Motor
Vehicle Safety Standard (CMVSS) 208 as applica-
ble at the time your vehicle was manufactured.
According to these requirements, the front Ad-
vanced Airbag System on the passenger’s side
has been certified for “suppression” for infants
approximately 12 months old and younger, and
for “low risk deployment” for children aged 3 to
6 years old (as defined in the standard).
The advanced airbag system will activate or deac-
tivate the front passenger's airbag based on the
occupancy of the seat. If a front airbag deploys
during an accident, the deployment force will
adapt to the passenger.
Components
The advanced airbag system consists of the fol-
lowing components:
— Front airbags in the steering wheel and in the
instrument panel on the front passenger's side:
these can protect the front passengers during
an accident
— Passenger occupant detection sensor in the
front passenger's seat: this detects if the front
passenger's seat is occupied (for example, by a
person or a small child in a child safety seat)
— Seat position sensors on the front seats: these
determine the distance between the seat and
the steering wheel or instrument panel
— Sensors in the front seat belt latch: these de-
tect if the safety belts are fastened
—The PASSENGER AIR BAG OFF #;, ON @
indicator light in the headliner: this indicates if
the front passenger's airbag is activated or de-
activated
- ka indicator light in the instrument cluster:
this monitors the function of the Advanced Air-
bag System components to ensure they are
functioning correctly
How the components function together
The passenger occupant detection sensor in the
front passenger's seat detects if the front pas-
senger's seat is occupied. The passenger

8W1012721BB
Sitting correctly and safely

occupant detection sensor measures the electri-
cal capacity on the front passenger’s seat. The
passenger's airbag is activated or deactivated de-
pending on the electrical capacity that is meas-
ured.
The passenger's airbag is activated if:
— The electrical capacity is higher than the
threshold stored in the control module
— The electrical capacity is the same as or greater
than the electrical capacity of a typical adult
The passenger's airbag is deactivated if:
— The electrical capacity is lower than the thresh-
old stored in the control module
— The electrical capacity is the same as or less
than the electrical capacity of a typical one-
year-old child in a child safety seat that has
been used for certification in accordance with
FMVSS 208
If the front passenger's airbag is activated, the
PASSENGER AIR BAG ON @ indicator light
will turn on. If the front passenger's airbag is de-
activated, the PASSENGER AIR BAG OFF #;
indicator light will turn on.
The deployment force of the front airbags adapts
based on whether or not the safety belt is used
and the distance between the seat and the steer-
ing wheel/instrument panel. For example, if a
person is too close to the front airbag, the front
airbag will deploy with less force to help reduce
the risk of injury.
Meaning of PASSENGER AIR BAG OFF 3; ON
® indicator light
When the ignition is switched on, the system de-
tects whether the front passenger's seat is occu-
pied. PASSENGER AIR BAG OFF #;, ON @
will turn on for several seconds during this proc-
ess. Then it will indicate whether the front pas-
senger's airbag is activated or deactivated.
— PASSENGER AIR BAG OFF 8¥;: the front
passenger's airbag is deactivated and will not
deploy in the event of an accident.
— PASSENGER AIR BAG ON @®: the front pas-
senger's airbag is activated and could deploy in
the event of an accident.
If a change to the occupancy status of the front
passenger's seat is detected,
PASSENGER AIR BAG OFF #, ON @ will
flash for several seconds and will then display the
status of the front passenger's airbag.
Always make sure the indicator light corresponds
to the occupancy of the front passenger's seat.
— An adult or individual of similar size in the
front passenger's seat: the front passenger's
airbag must be activated, so
PASSENGER AIR BAG ON ® must remain
on.
— An individual of smaller size (for example, an
adolescent or small adult) in the front pas-
senger's seat: the front passenger's airbag
must be activated, so
PASSENGER AIR BAG ON @ must remain
on.
— Child in a child safety seat on the front pas-
senger's seat: the front passenger's airbag
must be deactivated, so
PASSENGER AIR BAG OFF #%; must remain
on.
— Front passenger's seat not occupied: the front
passenger's airbag must be deactivated, so
PASSENGER AIR BAG OFF ®, must remain
on.

ZA\ WARNING
— An adult or a person with a small stature
(such as a young person or small adult) seat-
ed on the front passenger's seat will not be
protected by the passenger's airbag in the
event of a collision if the passenger's airbag
is deactivated. This increases the risk of in-
jury and death. Always make sure that
PASSENGER AIR BAG ON ® remains on
while driving. If
PASSENGER AIR BAG ON @ does not
turn on, make sure the front passenger is
sitting correctly in the seat > page 59 and
that there are no objects covering the front
passenger's seat (such as blankets or pil-
lows). If PASSENGER AIR BAG ON ®
still does not turn on, the front passenger's
seat must not be used. Drive to an author-
ized Audi dealer or authorized Audi Service

hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Store objects securely while
driving.
— Only use the storage compartments in the
door trim panels to store small objects that
will not stick out of the compartment and
impair the function of the side airbags.
— Due to strength reasons, only secure objects
up to 11 lbs (5 kg) with the tie-downs*.
Heavier objects are not adequately secured.
There is risk of personal injury.
— Applies to: vehicles with garment hooks: On-
ly lightweight clothing should be hung from

Luggage compartment
General information
All pieces of luggage or objects must be securely
fastened in the luggage compartment. Note the
following to maintain good vehicle handling:
> Distribute the load evenly in the luggage com-
partment.
> Stow heavy luggage as far forward in the lug-
gage compartment as possible.
> Use non-elastic cords attached to the tie-downs
to secure objects.

ZA\ WARNING
— Applies to: vehicles with luggage compart-
ment cover: The luggage compartment cov-
er is not a surface for storing objects. Ob-
jects placed on the cover increase the risk of
injury to all vehicle occupants during sudden
driving or braking maneuvers or in the event

of an accident. >

Stowing and using


— Applies to: vehicles with luggage compart-
ment cover: The luggage compartment cov-
er must always be securely fastened when in
use to reduce the risk of an accident.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Always stow objects securely in
the luggage compartment and secure them
at the tie-downs. Use straps suitable for
heavy objects.
— If pieces of luggage or objects are secured
to the tie-downs with unsuitable or dam-
aged straps, this can increase the risk of in-
jury during braking maneuvers or accidents.
— When transporting heavy objects, the vehi-
cle characteristics will change due to the
shift in the center of gravity, which increases
the risk of an accident. You may need to
adapt your driving style and speed to the
current conditions.
— The cargo net is only strong enough to se-
cure light objects. Heavy objects are not ade-
quately secured. Attempting to secure heavy
objects increases the risk of injury.
— Never exceed the permitted axle and load
and vehicle weight > page 278.
— Never secure a child safety seat to the tie-
downs.
— Never leave your vehicle unattended, espe-
cially if the luggage compartment lid is
open. Children could enter the luggage com-
partment and close the luggage compart-
ment lid from the inside. This creates the
risk of fatal injury, since the children would
be locked in and may not be able to escape
by themselves.
— Do not allow children to play in or on the ve-
hicle. Close and lock the luggage compart-
ment lid as well as all other doors when you
leave
the vehicle.
— Never transport passengers in the luggage
compartment. Every passenger must be cor-
rectly secured with the safety belts in the
vehicle > page 64.
— Be careful when releasing the backrest and
folding
it forward. To reduce the risk of be-


ing pinched, pay attention and check when
folding backrests forward.
— The backrest must be securely latched so
objects cannot slide forward out of the lug-
gage compartment during sudden braking.
— The backrest must be latched securely to en-
sure that the safety belt is protecting the
center seating position.
— Always pull forward on the backrest to make
sure it is check if it is correctly locked in
place.


80
() Note
—To reduce the risk of damage, move the rear
head restraints down before folding the rear
backrests forward > page 63.
— When folding the backrest forward, make
sure the outer safety belts are in the belt
guide recess so that they do not get pinched
in the backrest lock and damaged. Other ob-
jects should be removed from the rear
bench seat to protect the backrest from
damage.
— To reduce the risk of damaging the front
seats, make sure there is enough space be-
tween the front seat and the rear seat
equipment when folding the center backrest
forward.
— If you move the front seat back when the
rear seat backrest is folded forward, you
could damage the head restraints on the
rear seat.
— Make sure that the heating grid strips for
the rear window defogger are not damaged
by abrasive objects.
— Applies to: vehicles with manual luggage
compartment cover: Let the luggage com-
partment cover roll up slowly to reduce the
risk of damage.
— Applies to: vehicles with partition net: Let
the partition net roll up slowly to reduce the
risk of damage.
(i) Tips
— The tire pressure must be adapted to the
load > page 237.
— You can purchase straps at specialty stores.
