Safety systems monitoring

which increases the risk of serious injuries or

death. Only have an authorized Audi dealer

or authorized Audi Service Facility make re-

pairs or modifications to a vehicle.

The  indicator light in the instrument cluster

monitors the safety systems such as the airbags

(including the control modules, sensor, and wir-

ing) and the belt tensioners. It turns on when you

turn on the ignition and turns off after several

seconds.

– 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.

If the indicator light does not turn on when the

ignition is turned on, does not turn off after sev-

eral seconds, or turns on or flashes while driving,

there may be a malfunction in one of the safety

systems. Drive to an authorized Audi dealer or

authorized Audi Service Facility immediately to

have the malfunction corrected.

– 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.

WARNING

Have the malfunction in the safety systems in-

spected immediately. Otherwise, there is a

risk that the systems may not activate during

an accident, which increases the risk of seri-

ous injury or death.

Tips

If you are transporting children in the vehicle,

read the information and follow the safety

precautions ðpage 79.

Sitting correctly and safely

Description

Fig. 71 Airbag overview image (deployment area/deployed airbags)

The locations of the airbags are labeled with

“AIRBAG”. The following airbags are installed in

your vehicle:

condition of the object that the vehicle hits (hard

or soft), the angle of impact, vehicle speed, etc.

The deciding factor for the deployment of the air-

bag system is the deceleration that occurs during

an accident. Sensors in the vehicle are designed

to detect the severity of an accident in conjunc-

tion with the control module, and to provide a

targeted and timely deployment of the restraint

system. If the vehicle deceleration that is meas-

ured during an accident is below the specified

reference values in the control module, then the

airbags will not deploy, even though the vehicle

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.

Airbags offer the best possible protection in your

vehicle during an accident when they are used to-

gether with safety belts that are fastened cor-

rectly, and when vehicle occupants are sitting in a

correct seating position. Airbags are a supple-

mentary restraint system and do not replace

safety belts.

The deployment of the front passenger's airbag

will depend on the occupancy of the seat

ðpage 77.

Airbags may deploy during front impact, side im-

pact, or rollover accidents.

The deployment range for the airbag system can-

not be defined for every situation, since the cir-

cumstances surrounding accidents can vary wide-

ly. Factors that play an important role include the

within milliseconds. Inflated airbags reduce the

movement of persons in the vehicle who are

wearing safety belts in the direction of the im-

pact and thus help to reduce the risk of injury.

They can help to protect the head, upper body,

and lap, for example. However, there is the possi-

bility that airbag deployment can cause injuries.

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 a collision, the deployment force will

adapt to the person in the vehicle.

The airbag system works when the ignition is

turned on.

Components

The advanced airbag system consists of the fol-

lowing components:

If you or other passengers in the vehicle have

physical limitations that prevent sitting in a cor-

rect position, modifications to the vehicle may be

necessary. For more information, contact an au-

thorized Audi dealer or authorized Audi Service

Facility, or call Audi customer support at

1-800-822-2834.

– Front airbags in the steering wheel and in the

instrument panel on the front passenger's side:

these can protect persons in the front seats

during a collision

– 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 safety belt latch: these de-

tect if the safety belts are fastened

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.

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 occu-

pant detection sensor measures the electrical ca-

pacity on the front passenger’s seat. The pas-

senger's airbag is activated or deactivated de-

pending on the electrical capacity that is meas-

ured.

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 front passenger’s

side has been certified for “suppression” for in-

fants approximately 12 months old and younger,

The passenger's airbag is activated if:

– The electrical capacity is higher than the

threshold stored in the control module
