2018 AUDI A4 ESP

All of this takes place in the blink of an eye, so
fast that many people don't even realize that the airbags have deployed . The airbags also inflate
with a great deal of force and it is important for
occupant safety that nothing should be in their
way when they deploy .
Fully inflated airbags in comb ination with proper­
ly worn safety belts slow down and limit the oc­
cupant 's forward movement and help to reduce
the r isk of injury .
Important safety instructions on the knee
airbag system
Airbags are only supplemental restraints . Always
wear safety belts correctly and ride in a proper
seating position.
There is a lot that you and your passengers must
know and do to help the safety be lts and airbags
to provide s upplemental protection .
,& WARNING
An inflating knee airbag can cause ser ious in­
jury. Wearing safety bel ts incor rectly and im­
proper seating posit ions increase the r isk o f
serious personal injury and death whenever a
vehicle is being used.
- The knee airbag system cannot protect you
prope rly if you are seated too close to any of
the a irbag locat ions. When ad justing their
seat positions, it is important that both the
dr iver and the front passenger keep their
upper bod ies a nd knees at the following
min imum safe d istances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instrument
panel.
- at least 4 inc hes (10 cm) between the
knees and the lower part of the instru­
ment panel.
- The risk of persona l injury increases if you
lean forward or to the side, or if the seat is
improper ly positioned and you are not wear­
ing your safety belt. The risk increases even
more should the a irbag deploy.
- Always make sure that the knee airbag can
inflate without interference. Objects
be-
Airb ag sys tem
tween you and the airbag can increase the
risk of injury in an accident by interfering
wit h the way the airbag deploys or by being
pushed into yo u as the a irbag deploys.
- Never let anybo dy, especi ally children or
anima ls r ide in the footwell i n front of the
passenger seat. If the airbag deploys, this
can result in serious o r fatal in juries.
- Never carry objects of any kind in the foo t­
well area in front of the driver's or pas­
senger's seat . Bulky objects (shopp ing
bags, for example) can interfere with or
prevent proper dep loyment of the airbag.
Small objects can be thrown th rough t he
vehicle if the airbag deploys and injure you
o r your passengers.
- Make sure the re a re no cracks, deep scratch­
es o r othe r damage in the area of the inst ru­
ment panel where the knee airbags a re lo­
ca ted.
- If ch ildren are incorrectly seated, their risk
of injury inc reases in a coll is ion

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fi g. 2 44 Side a irbag locat ion in the drive r's sea t
The side airbags are located in the s ides of the
front seat
backrests ~ fig. 244 and the rear back­
res t* facing the doo rs.
The side airbags installed for the front seating
pos itions have been des igned and certified to
help reduce the risk of in ju ry that can be caused
by a irbags when they inflate, pa rticul arly when

the airbag will inflate when it is not
supposed
to, or will not inflate when it
should.
How supplemental side airbags work
Side airbags deploy instantly and can help re­ duce the risk of upper torso injuries for occu­
pants who are properly restrained.
Fig. 245 Infla ted side airbags on left side of veh icle, rear
side airbag opt ional equipment
When the system is triggered, the airbag is filled
with propellant gas and breaks through a seam in
the seat surface area.
It expands between the
side trim panel and the passenger. In order to
help provide this additional protection, the side
airbag must inflate within a fraction of a second
at very high speed and with great force . The sup­
plemental side airbag could injure you if your
seating position is not proper or upright or if
items are locat ed in the area where the supple­
mental side airbag expands. This applies espe­
cially to
children¢ page 295, Child safety. Sup­
plemental side airbags inf late between the occu­
pant and the door panel on the side of the vehicle
that is struck in certain side
collision ¢ fig. 245.
Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
help to reduce the risk of injury to the upper part
of the body.
A fine dust may develop when the airbag deploys.
This is normal and does not mean there is a fire
in the vehicle .
Airbag system
Important safety instructions on the side
airbag system
Airbags are only supplemental restraints. Always
properly wear safety belts and ride in a proper
seating position .
There is a lot that you and your passengers must
know and act accordingly to help the safety belts
and airbags do their job to provide supplemental
protection.
A WARNING
An inflating side airbag can cause serious or
fatal injury. Improperly wearing safety belts
and improper seating positions increase the
risk of serious personal injury and death
whenever a vehicle is being used.
- In order to reduce the risk of injury when
the supplemental side airbag inflates:
- Always sit in an upright position and never
lean against the area where the supple­
mental side airbag is located.
- Never let a child or anyone else rest their
head against the side trim panel in the
area where the supplemental side airbag inflates.
- Always make sure that safety belts are
worn correctly,
- Do not let anyone sitting in the front seat
put their hand or any other parts of their
body out of the window.
- Always make sure that the side airbag can
inflate without interference.
- Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
Audi.
- Never use additional seat cushions that
cover the areas where the side airbags de­ ploy.
- 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.
-
- Objects between you and the airbag can in­
crease the risk of injury in an accident by in­
terfering with the way the airbag unfolds or

There is a lot that yo u and your passengers must
know and do to help the safety be lts and airbags
do their job to provide supplemental protect ion.
A WARNING
Improperly wearing safety belts and improper
seating posit ions increase the risk of serious
personal inju ry and death whenever a vehicle
is being used.
- Never let occupants p lace any parts of the ir
bodies in the area from which the side cur­
ta in a irbag inflate.
- Always make sure that the side curtain air­
bags can inflate witho ut interferen ce.
- Use the built- in coat hooks on ly for light­
weight cloth ing. Neve r leave any heavy or
sharp-edged obje cts in t he pockets that may
in terfere w ith airbag deployment and can
ca use personal injury in a collision.
- Never use hangers to hang clothes on the
hoo ks.
- Only use factory-installed s un shades or, if
shades installed after the veh icle leaves the
factory, use only genuine Aud i sun shades.
- Never swing the sun viso rs ove r to the side
windows if things such as pens, ga rage door
openers, hands-free speakers, etc . are at­
tached to the sun visors. They co uld come
294
loose and cause serious injury if the side cu r­
tain airbag inflates.
- A deploying airbag inflates in a fraction of a
second and with great force.
- Never attach objects to the cover or in the
deployment zone of a side curtain airbag .
- The a irbag deployment zones must be kept
clear at all times. Make s ure there are no
objects, pets, o r other persons in the space
between any vehicle occupant and any air­
bag at any time.
- Do not attach any accessories to the doors.
A WARNING
- The a irbag system can deploy on ly once. If
the airbag has been triggered, the system
m ust be rep laced by an authorized A udi
dealer or qualified workshop .
- Always have work invo lv ing the side curtain
airbag system, remova l and installat ion of
the airbag components, or other repairs
pe rformed by a q ualified dealership. Other­
w ise the airbag system may not work cor­
rectly.
- Never attempt to mod ify any componen ts of
the airbag system in any way.

Child safety
Important information
Introduction
The rear seat is generally the safest place in a
collision .
The physical principles of what happens when
your vehicle is in a crash apply also to children
c:> page 264, What happens to occupants not
wearing safety belts? .
But unlike adults and
teenagers, their muscles and bones are not fully
developed. In many respects children are at
greater r isk of serious injury in crashes than
adults .
Because children's bodies are not fu lly devel­
oped, they require restraint systems especially
designed for their size, weight, and body struc­
ture. Many countries and all states of the United
States and provinces of Canada have laws requir­
ing the use of approved child restraint systems
for infants and small children .
I n a frontal crash at a speed of 20 -35 mph (30 -
56 km/h) the forces acting on a 13-pound (6 kg)
infant will be more than 20 times the weight of
the child . This means the weight of the chi ld
would suddenly be more than 260 pounds (120 kg) . Under these conditions, only an appro­
priate child restraint properly used can reduce
the r isk of serious injury . Child restra ints, like
adult safety belts, must be used properly to be
effect ive. Used improperly, they can inc rease the
risk of serious injury in an accident.
All ch ildren, especially those 12 years and young­
er must always ride in the back seat proper ly re­
stra ined for their age and size. If you must install
a child restraint on the front passenger seat in
exceptional circumstances, be sure to read and
heed the important information and warnings
c:> page 2 72. Infants and other children who are
properly restrained in an appropriate child re­
straint that is for their size and age can benefit
from the protection that supplemental side air­
bags provide in some kinds of crashes.

(NHTSA), currently at: http:/ /www.safe ­
rcar.gov (for the USA)
- Transport Canada Information Centre, current-
ly at: http://www.tc .gc.ca (for Canada)
Consult the child safety seat manufacturer's in­
structions in order to be sure the seat is right for
yo ur child's size
c:> page 299, Important safety
instructions for using child safety seats .
Please
be sure to read and heed all of the important in­
formation and WARNINGS about child safety,
Advanced Airbags, and the installation of child
restra ints in this chapter .
There is a lot you need to know about the Ad­
vanced Airbags in your vehicle and how they work
when infants and children in child restraints are on the front passenger seat . Because of the large
amount of important informat ion, we cannot re­
peat it all he re. We urge you to read the detailed
information in this owner 's manual about airbags
and the Advanced Airbag Sys tem in yo ur vehicle
and the very important information about trans­
porting children on the front passenger seat.
P lease be sure to heed the WARNINGS -they are
extremely important for your safety and the safe­
ty of your passengers, especially infants and
small children.
A WARNING
-- Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seat ing pos ition. Always restrain
any child age 12 and under in the rear.
- All vehicle occupants and especially children
must be restrained properly whenever riding
in a vehicle. An unrestrained or imp roperly
rest rained child could be injured by striking
the interior or by being ejected from the ve­ hicle during a sudden maneuver or impact.
An unrestrained or improperly restrained
child is also at greater r isk of injury or death
through contact w ith an inflating a irbag.
-A suitable ch ild restraint properly installed
and used at one of the rear seating positions
provides the h ighest degree of protect ion
for infants and small children in most acci­
dent situat ions.

does not come on and stay on, immediate­
ly install the forward-facing child seat in a
rear seating position and have the airbag
system inspected by your authorized Aud i
dealer.
- Always buckle the child seat firmly in
p lace even if a ch ild is not sitt ing in it. A
loose child seat can fly around during a
sudden stop o r in a collision.
-Always read and heed all WARNINGS whenever using a child restraint in a vehi­
cle ~ page 263, Safety belts, ~ page 2 71,
Airbag system
and ~ page 295, Impor­
tant information .
@ Tips
Always replace ch ild restraints that were in­
stalled in a vehicle dur ing a crash. Damage to
a child restraint that is not visib le co uld cause
it to fail in anothe r collision situation .
Advanced front airbag system and children
Your vehicle is equipped with an "Advanced Air­
bag System" in compliance with United States
Federal Motor Vehicle Safety Standard (FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your veh icle was manufactured.
The Advanced Airbag system in your vehicle has
been certified to meet the "low-risk" require­
ments for
3-and 6-year old children on the pas­
senger side and small adults on the driver side.
The low risk deployment crite ria are intended to
reduce the risk of injury through inte raction with
the airbag that can occur, for examp le, by being
too close to the steering whee l and instrument
panel when the airbag inflates . In addition, the
system has been certified to comply with the
"suppression" req uirements of the Safety Stand­
ard, to turn off the front airbag for infants up to
12 months who are restra ined on the front pas­
senger seat in child restraints that are listed in
the Standard .
Child safety
Even though your vehicle is equipped with an Ad­
vanced Airbag system, all chi ldren, especially
those 12 years and younger, should always ride in the back seat properly restrained for their age
and size. The airbag on the passenger side makes
the front seat a potentia lly dangerous place for a
child to ride . The front seat is not the safest place
for a ch ild in a forward-fac ing ch ild safety seat .
It
can be a very dangerous place fo r an infant o r a
la rger ch ild i n a rea rwa rd-facing seat .
T he veh icle 's Advanced Airbag System has a ca­
pacit ive passenger detection system in the front
passenge r seat cushion that can detect the p res­
ence of a baby or a ch ild in a child restra int sys­
tem on this seat .
The capacitive passenger detection system reg is­
te rs the changes that result in an electrical field
when a child, a ch ild restraint, and a baby b lan ket
are on the front passenger seat. The change in
the measured capacitance due to the presence of
a chi ld, a child restraint, and a baby blanket on
the front passenger seat is related to the child
restra int system resting on the seat. The meas­
ured capacitance of a child restraint system var­
ies depend ing on the type of system and specific
make and model.
The electrical capac itance of the various types,
makes, and models of child restraints specif ied
by the U .S.National Highway Traff ic Safety Ad ­
min istrat ion (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys­
tem contro l unit together with the capacitances
typ ica l of infants and a 1-year old child. When a
child restraint is used on the front passenger
seat with a typical 1 year-old infant, the Ad­
vanced Airbag System compares the capacitance
measured by the capacitive passenger detection
system with the data stored in the electronic con­
trol unit .
Child restraints and Advanced Airbags
Regardless of the ch ild restraint that you use,
make sure that it has been certified to meet Safe­
ty Standards and has been ce rt ified by its manu­
fact urer for use w ith an airbag . Always be su re
that the child restraint is properly installed at

Important safety instructions for using
child safety seats
Correc t use of child safety sea ts substan tially re­
duces the risk of injury in an accident!
As the driver, you are responsible for the safety
of everybody in the vehicle, especially children:
~ Always use the right child safety seat for each
child and a lways use it
properly ~ page 301.
~ Always carefully follow the child safety seat
manufacturer 's instructions on how to route
the safety belt properly through the child safe­
ty seat .
~ When using the vehicle safety be lt to install a
child safety seat , you must first activate the
convertible locking retractor on the safety be lt
to prevent the child safety seat from moving
¢ page 306.
~ Push the child safety seat down with your fu ll
weight to get the safety be lt really tight so that
the seat cannot move forward or sideways
more than one inch (2.5 cm).
~ Secure unused safety belts on the rear seat
¢ page 301 .
Always remember: Even though your vehicle is
equipped with an Advanced Airbag system, all
children, especially those 12 years and younger,
should always ride in the back seat properly re­
stra ined fo r their age and size.
_& WARNING
Not using a ch ild safety seat, using the wrong
child safety seat or improper ly installing a
Ch ild safety
child restraint increases the risk of serious
personal injury and death.
-All vehicle occupants and especially children
must be restrained properly whenever riding
in a vehicle. An unrestra ined or improperly
restrained child could be injured by striking
the inter ior or by being ejected from the ve­
hicle dur ing a sudden maneuve r or impact .
An unrest rained or improperly restrained
child is a lso at greater r is k of injury or death
through contact w ith an inflating a irbag.
-Commerc ially availab le child safe ty seats
are requi red to comply with U.S . Federal
Motor Vehicle Safety Standard (FMVSS) 213
(in Canada CMVSS 213).
-When buying a child restra int, select one
that fits your ch ild and the vehicle .
-Only use child restraint systems that fully
contact the flat portion of the seat cush­
ion. The ch ild restraint must not t ip or
lean to either side . Audi does not recom­
mend using child safety seats that rest on
legs or tube-like frames. They do not pro­
vide adequate contact with the seat.
-Always heed all lega l requirements per­
ta ining to the insta llation and use of child
safety seats and carefu lly follow the in­
structions provided by the manufacturer
of the seat you are using .
-Never allow children under 57 inches
(1.45 mete rs) to wear a normal safety be lt.
They must a lways be restrained by a proper
child restraint system. Otherwise, they
could sustain injuries to the abdomen and
neck areas during sudden braking maneu­
vers or accidents .
-Never let more than one child occupy a child
safety seat.
-Never let babies or o lder children ride in a
vehicle while sitting on the lap of another
passenger .
-Holding a child in your arms is never a sub­
stitute for a chi ld restrain t system .
- The strongest person cou ld not ho ld the
ch ild with the forces that exist in an acci­
dent. The child will strike the interior of
the vehicle and can also be struck by the passenger.

A WARNING
A child in a child safety seat installed with the
LATCH lower anchorages or with the standard
safety belt or a child in a booste r seat on the
rear seat could play with unused rear seat
safety belts and become entangled. This
cou ld cause the chi ld serious personal injury
and even death.
- Always secure unused rear seat safety belts
out of reach of children in child seats such
as by proper ly routing them aro und the

restraint is installed .
- Never activate the convertible locking re­
tractor when routing the safety belts around
the head restraints.
- Never let anyone sit at the center rear seat­
ing position if the center rear safety belt has
been routed around a rear head restraint.
Child safety seats
Infant seats
Babies and infants up to about one year old and
20 lbs. or
9 kg need special rearward-facing
child restraints that support the back, neck and
head in a crash.

Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs. and
80 lbs . (18 kg and 36 kg) who are less than 4
ft.
9 in. (57 inches/1.45 meters) tall.
Fig. 252 Rear seat; chi ld proper ly restrained in a booster
sea t
The vehicle's safety belts alone will not fit most
children until they are at least 4
ft. 9 in. (57 in­
ches/1.45 meters) tall and weigh about 80 lbs.
(36 kg). Booster seats raise these children up so
that the safety belt will pass properly over the
stronger parts of their bodies and the safety belt
can help protect them in a crash.
.,. Do not use the convertible locking retractor
when using the vehicle's safety belt to restrain
a chi ld on a booster seat .
.. The shoulder belt must lie as close to the cen­
ter of the child's collar bone as possible and
must lie fla t and snug on the upper body.
It
must never lie across the throat or neck. The
lap belt must lie across the pelvis and never
across the stomach or abdomen. Make sure the
belt lies flat and snug. Pull on the belt to tight­
en if necessary .
.,. If you must transport an older child in a boos­
ter seat on the front passenger seat , you can
use the safety belt height adjustment to help
adjust the shoulder portion properly .
.. Secure unused safety belts on the rear seat
r:=>page 301.
Children up to at least 8 years old (over 40 lbs. or
18 kg) are best protected in child safety seats
de­
signed for their age and we ight. Experts say that
the skeletal structure , part icularly the pelvis , of
these children is not fully developed, and they
Child safety
must not use the vehicle safety belts without a
suitable child restraint .
It is usually best to put these children in appro­
priate booster seats. Be su re the booster seat
meets all applicab le safety standards .
Booster seats raise the seating position of the
child and reposition both the lap and shoulder
parts of the safety belt so that they pass across
the child's body in the right places. The routing of
the belt over the chi ld's body is very important
for the ch ild's protection, whether or not a
boos­
ter seat is used. Children age 12 and under must
always ride in the rear seat.
Ch ildr en who are at least 4
ft. 9 in. (57 inches/
1.45 meters) tall can generally use the vehicle 's
three point lap and shoulder belts . Never use the
lap belt portion of the vehicle 's safety belt alone
to restrain any ch ild, regard less of how big the
ch ild is. Always remember that childr en do not
have the pronounced pelvic structure required for
the proper function of lap belt portion of the
ve­
hicle's three point lap and shoulder belts . T he
child's safety absolutely requires that a lap belt
portion of the safety belt be fastened snugly and
as low as possible around the pe lvis. Never let
the lap belt portion of the safety belt pass over
the child 's stomach or abdomen .
In a crash, airbags must inflate within a blink of
an eye and with considerab le force. In order to do
its job, the airbag needs room to inflate so that it
will be there to protect the occupant as the
occu­
pan t moves forward into the airbag .
A vehicle occ upant who is out of position and too
close to the a irbag gets in the way of an inflating
airbag. When an occupant is too close , he or she
will be struck violently and will receive serious or possibly even fata l injury .
In order for the airbag to offer protection, it is
important that all vehicle occupants, especially
any children, who must be in the front seat
be­
cause of exceptiona l circumstances, be properly
restrained and as far away from the airbag as
poss ible. By keeping room between the child 's
