What impairs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted.
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety
risks for everybody in the vehicle increase and you also
become a hazard to everyone else on the road
=>& .There ­
fore:
Do not let yourself be distracted by passengers or by
using a cellular telephone .
NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc.).
- Observe all traffic laws, rules of the road and speed limits
and plain common sense .
- ALWAYS adjust your speed to road, traffic and weather
conditions.
- Take frequent breaks on long trips. Do not drive for more
than two hours at a stretch.
- Do NOT drive when you are tired, under pressure or when
you are stressed .
& WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used. •

Child restraints on the front seat - some
important things to know
- Be sure to read the important information and head the
WARNINGS for important details about children and
Advanced
Airbags=> page 210.
Even though your vehicle is equipped with an Advanced Airbag
System, make certain that all children, especially those 12 years and
younger, always ride in the back seat properly restrained for their
age and size . The airbag on the passenger side makes the front seat
a potentially dangerous place for a child to ride. The front seat is not
the safest place for a child in a forward -facing child safety seat. It
can be a very dangerous place for an infant or a child in a rearward ­
facing seat.
The Advanced Airbag System in your vehicle has been certified to comply with the Requirements of United States Federal Motor
Vehicle Safety Standard 208 as applicable at the time your vehicle
was manufactured.
The Standard requires the front airbag on the passenger side to be
turned off ("suppressed") if a child up to about one year of age
restrained in one of the rear-facing or forward-facing infant
restraints listed in Federal Motor Vehicle Safety Standard 208 with
which the Advanced Airbag System in your vehicle was certified has been installed on the front passenger seat. For a listing of the child
restraints that were used to certify compliance with the US Safety
Standard ::::, page 212.
The PASSENGER AIR BAG OFF light in the instrument panel tells you
when the front Advanced Airbag on the passenger side has been
turned off by the electronic control unit.
Each time you turn on the ignition, the
PASSENGER AIR BAG OFF
light will come on for a few seconds and:
• will stay on if the front passenger seat is not occupied,
Controls and equip­
ment Safety first
Vehicle operation
• will stay on if there is a small child or child restraint on the front
passenger seat,
• will go off if the front passenger seat is occupied by an adult as
registered by the weight-sensing
mat ::::, page 198, "Monitoring the
Advanced Airbag System" .
The
PASSENGER AIR BAG OFF light comes on when the control unit
detects a total weight on the front passenger seat that requires the
front airbag to be turned off.
If the total weight on the front passenger seat is more than that of
a typical 1 year-old child but less than the weight of a small adult,
the front airbag on the passenger side can deploy (the
PASSENGER
AIR BAG OFF
light does not come on). If the PASSENGER AIR BAG
OFF
light does not come on, the front airbag on the passenger side
has not been turned off by the electronic control unit and can
deploy if the control unit senses an impact that meets the condi­
tions stored in its memory.
For example, the airbag may deploy if:
• a small child that is heavier than a typical 1 year-old child is on
the front passenger seat (regardless of whether the child is in one
of the child safety seats
listed ::::, page 212), or
• a child who has outgrown child restraints is on the front
passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG
OFF
light comes on in the instrument cluster and stays on.
The front airbag on the passenger side may
not deploy (the
PASSENGER AIR BAG OFF light does not illuminate and stay lit) even
if a small adult or teenager, or a passenger who is not sitting upright
with their back against a non-reclined backrest with their feet on the
vehicle floor in front of the seat is on the front passenger seat
=> page 168, "Proper seating position for the driver".
If the front passenger airbag deploys, the Federal Standard requires
the airbag to meet the "low risk" deployment criteria to reduce the risk of injury through interaction with the airbag . "Low risk" deploy­
ment occurs in those crashes that take place at lower decelerations _,,.

& WARNING
A child in a rearward -facing child safety seat installed on the front
passenger seat will be seriously injured and can be killed if the
front airbag inflates
-even with an Advanced Airbag System .
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the ba ckrest , center arm rest , door or roof .
• Always install rear-facing child safety seats on the rear seat .
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on ,
immediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
Audi dealer .
• Forward-facing child safety seats installed on the front
passenger's seat may interfere with the deployment of the airbag
and cause serious personal injury to the child .
& WARNING
If, in exceptional circumstances , you must install a forward-facing
child restraint on the front passenger's seat:
& WARNING (continued)
• Always make sure the forward-facing seat has been designed
and certified by its manufacturer for use on a front seat with a
passenger front and side airbag .
• Never put the forward-facing child restraint up against or very
near the instrument panel.
• Always move the passenger seat into its rearmost position in
the seat's fore and aft adjustment range, as far away from the
airbag as possible before installing the forward-facing child
restraint. The backrest must be adjusted to an upright position.
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on.
& WARNING
To reduce the risk of serious injury , make sure that the PASSENGER
AIR BAG OFF light will be displayed whenever a child restraint is
installed on the front passenger seat and the ignition is switched
on.
• If the PASSENGER AIR BAG OFF light does not stay on, perform
the checks
described => page 198, "Monitoring the Advanced
Airbag System" .
• Take the child restraint off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR
BAG OFF light does not stay on.
• Have the airbag system inspected by your Audi dealer immedi ­
ately .
• Always carefully follow instructions from child restraint manu ­
facturers when installing child restraints .
& WARNING
If, in exceptional circumstances, you must install a forward or
rearward -facing child restraint on the front passenger's seat :

& WARNING
To reduce the risk of injury when an airbag inflates, always wear
safety belts properly .
• If you are unrestrained , leaning forward , sitting sideways or out
of position in any way , your risk of injury is mu ch higher .
• You will al so receive serious injuries and could even be killed if
you are up again st the airbag or too close to it when it inflates -
even with an Advanced
Airbag => page 187.
& WARNING
A child in a rearward-facing child safety seat installed on the front
passenger seat will be ser iously injured and can be killed if the
front airbag inflate s -even with an Advanced Airbag System.
• Although the Advan ced Airbag System in your vehicle is
designed to turn off the front airbag when a rearward -facing child
restraint has been installed on the front passenger seat , nobody
can ab solutely guarantee that deployment is impo ssible in all
c onceivable situat ions that may happen during the useful life of
your vehicle. _,,.
