AUDI S4 2014 Owners Manual

-Always be especially careful if you must
install a rearward facing child safety seat
on the front passenger seat in exception­
al circumstances.
- A tight tether strap on a rearward-facing
child restraint attached to the front pas­
senger seat can put too much pressure
on the weight-mat in the seat and regis­
ter a heavier weight in the Advanced Air­
bag System. The heavier weight regis­
tered can make the system work as
though an adult were on the seat and de­ ploy the Advanced Airbag when it must
be suppressed causing serious or even
fatal injury to the child.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched
on.
- If the PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install the rearward-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer.
Activating the convertible lock ing
retractor
Use the convertible locking retractor to se­
cure a child restraint.
Always heed the child safety seat manufactur­
er's instructions when installing a child re­
straint in your vehicle. To activate the conver­
tible locking retractor:
.. Place the child restraint on a seat, prefera­
bly on the rear seat.
.. Slowly pull the belt
all the way out.
.. Route it around or through the child re­
straint belt path¢.&,_.
.. Push the child safety seat down with your
full weight to get the safety belt really tight.
.. Insert the belt tongue into the buckle for
that seating position .
.. Guide the safety belt back into the retractor
until the belt lies flat and snug on the child
safety seat .
Child Safety 1 79
.. You should hear a "clicking" noise as the
belt winds back into the inertia reel. Test the
convertible locking retractor by pulling on
the belt. You should no longer be able to
pull the belt out of the retractor. The con­
vertible locking retractor is now activated .
.. Make sure that the red release button is fac­
ing away from the child restraint so that it
can be unbuckled quickly.
.. Pull on the belt to make sure the safety belt
is properly tight and fastened so that the
seat cannot move forward or sideways more
than one inch (2.5 cm).
A WARNING
Using the wrong child restraint or an im­
properly installed child restraint can cause
serious personal injury or death in a crash.
- Always make sure that the safety belt re-
tractor is locked when installing a child
safety seat. An unlocked safety belt re­
tractor cannot hold the child safety seat in place during normal driving or in a
crash.
- Always buckle the child safety seat firmly
in place even if a child is not sitting in it.
A loose child safety seat can fly around
during a sudden stop or in a crash.
- Always make sure the seat backrest to
which the child restraint is installed is in
an upright position and securely latched
into place and cannot fold forward. Oth­
erwise, the seatback with the child safety
seat attached to it could fly forward in
the event of an accident or other emer­
gency situation .

180 Child Safety
Deactivating the convertible locking
retractor
The convertible locking retractor for child re­
straints will be deactivated automatically when the belt is wound all the way back into the retractor .
.,. Press the red button on the safety belt buck­
le. The belt tongue will pop out of the buck­
le .
.. Guide the safety belt all the way back into
its stowed position.
Always let the safety belt retract completely into its stowed position. The safety belt can
now be used as an ordinary safety belt with­
out the convertible locking retractor for child
restraints.
If the convertible locking retractor should be
activated inadvertently, the safety belt must
be unfastened and guided completely back in­
to its stowed position to deactivate this fea­
ture. If the convertible locking retractor is not
deactivated, the safety belt will gradually be­
come tighter and uncomfortable to wear .
A WARNING
Improperly installed child safety seats in­
crease the risk of serious personal injury
and death in a collision.
- Never unfasten the safety belt to deacti­
vate the convertible locking retractor for
child restraints while the vehicle is mov­
ing. You would not be restrained and
could be seriously injured in an accident.
- Always read and heed all WARNINGS
whenever using a child restrained in ave­
hicle is being used¢

LATCH Lower
anchorages and tether
for children
Child Restraint System anchors and how
are they related to child safety
To provide a s impler and more pract icable way
to attach the child restraint on the vehicle
seat, Federal regu lations require special lower
anchorages in vehicles and dev ices on new
child restraints to attach to the vehicle ancho­
rages.
The combination of the tether anchorages and
the lower anchorages is now generally called
the
LA TCH system for "Lower Anchorages and
Tethers for Children ."
F orward-facing child restraints manufactured
after September 1, 1999, are required by U.S.
federal regulations to comply with new ch ild
head movement performance requirements .
T hese new performance requirements make a
tether necessary on most new child seats.
I nstalling a chi ld restraint that requires a top
tether without one can seriously impair the
performance of the chi ld restraint and its ab il­
ity to protect the child in a co llision . Installing
a child restraint that requires a top tether
without the top tether may be a v iolation of
state law.
Ch ild restraint manufacturers offer LATCH
lower anchorages on their ch ild seats with
hook -on or push-on connectors attached to
adj ustable straps.
In addition to the LATCH lower anchorages,
these child restraint systems usually require
the use of tether straps to help keep the child
restra int firmly in place .
A WARNING
Improper insta llation of chi ld restraints
w ill increase the risk of inju ry and death in
a crash.
- Always follow the instructions p rov ided
by the manufacturer of the ch ild re-
Child S afety 181
straint you intend to install in your vehi­
cle.
- Never install a chi ld restraint without a
properly attached top tether strap if the
child restraint manufacturer's instruc­
tions require the top tether strap to be
used.
- Improper use of child restraint LATC H
lower anchorage points can lead to injury
in a collision . The LATC H lowe r anchorage
points ar e designed to withstand on ly
those loads imposed by correctly fitted
child restraints.
- Never mo unt two ch ild restra int systems
on one LA T C H l ower anchorage point.
- Never secure or a ttach any luggage or
o ther item to the LATCH lower anchorag­
es.
a) Tips
In Canada, the terms "top tether" with
"lower u niversal anchorages" (or "lower
universa l anchorage ba rs") are used to de­
scribe the sys tem.
- In other countries, the t erm " ISOFIX" is
used to describe the lower a nch o rages.

Lower anchorages secure the child restraint in
the seat without using the vehicle 's safety
belts. Anchorages provide a secure and easy­
to-use attachment and m inim ize the possibili­
ty of improper child restraint installation .
All chi ld restraints manufactured after Sep­
tember 1 , 2002, must have lower anchorage
attachments for the
LATCH system .
Remember that the lower anchorage points
are only intended for installation and attach­ ment of child restraints specifically certified
for use w ith
LATCH lower anchorages. Child
restra ints that are not equipped with the low­
e r anchorage attachments can still be instal- led in compliance with the child restraint
manufacturer's instructions on using vehicle
safety belts
.
A WARNING
-Improper use of LATCH lower anchorages
can cause serious personal injury in an ac­
cident.
- Always carefully follow the child re­
straints manufacturer's instructions for
proper installation of the child restraint
an d prope r use of the lower anchorages
or safety belts in your vehicle .
- Never secure or attach any luggage or
other items to the
LATCH lower ancho­

A tether is a straight or V-shaped strap t hat
attaches the top part of a ch ild restraint to
special anchorage po ints in the vehicle .
T he purpose of the tethe r is to re duce the for­
ward movement of the child rest raint in a
crash, in orde r to help reduce the risk of head
injury that cou ld be caused by striking the ve­
hicle interior.
Forward facing child restraints manufactured
after September 1, 1999, are requ ired by U .S .
federal regulations to comply with c hild head
movement performance requirements. These
new performance requirements make a tether
necessary on most new child safety seats. ...,

& WARNING
Improper insta llation of child restraints
will increase the risk of injury and death in a crash.
- Always follow the instructions provided
by the manufacturer of the ch ild re­
straint you intend to install in your Audi.
- Improper use of child restra int anchors
(including tether anchors) can lead to in­
jury in a co llision. The anchors are de­
signed to withstand on ly those loads im­
posed by correctly fi tted ch ild restraints.
- Never mount two ch ild restraint systems
on one LA TCH lower anchor po int.
- Never attach two child rest ra int systems
to one tethe r strap or tether anchorage.
- Never attach a tether strap to a tie-down
hook in the luggage compartment.
- Never use ch ild restra int te ther ancho­
rages to secure safety belts o r other
kinds of oc cupant rest ra ints.
- Never secure o r attach any luggage or
other items to the LATC H lowe r ancho­
rages o r to the tethe r ancho rs.
- If a tether or other strap is used to at­
tac h a child res traint to the front passen­
ger seat, make su re that it is not so
t igh t, that it causes the weight-sensing
mat to measure more weight than is ac­
t u ally on the seat.
- T he heav ier weight reg iste red can make
the Advanced Airbag System work as
though an adult were on the seat and de­
ploy the Advanced Airbag when it must
be suppressed causing serious or even
fatal injury to the child.

seats.
Using tether straps on rearward-facing
child restraints
Currently, few rearward-facing child restraint
systems come with a tether. Please read and h eed the child restraint system manufactur­
er's instructions carefully to determ ine how to
p roperly install the tethe r.

Notice about data
recorded by vehicle
control modules
Your veh icle is not equipped with an Event Da­
ta Recorde r (EDR), ins talled by some manu­
facture rs fo r the express p urpose of capturing
data for retrieval after an accident or cras h
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restr ict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of retrieving data after an accident or crash
event without the owner's consent.
A ltho ugh yo ur vehicle is not equ ipped wit h an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, eng ine f unction, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during norma l vehicle op­
erat ion for diagnostic and repa ir purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded ove r a ve ry limited pe riod of
time and stored when a sys tem faul t or o ther
cond ition is sensed by a cont ro l u nit. Some of
the data then stored may re late to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condit ion. Stored data can only
be read and downloaded w ith special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of ve hicle control. It works
only when the eng ine is running. ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
o ut of control and he lps you to get the veh icle
back under control by se lectively braking the
whee ls, and/or reducing eng ine power and
providing steer ing ass istance to he lp hold the
vehicle o n the dr iver's intended course. The in­
dicator light
J.i) in the instrument cluster
blinks when ESC is ta king action to help yo u
control the veh icle.
ESC has limitations.
It is importa nt to remem­
ber that ESC cannot overcome the laws of
physics. It will not always be able to help out
under a ll cond it ions you may come up aga inst.
F or example, ESC may not always be able to
help you master situations where there is a
s u dden change in the coefficient of friction of
the road surface. When there is a section of dry road that is sudden ly covered w ith water,
s lush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the ve hicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle be cause con­
tact with the pavement has been in terrupted
and the vehicle cannot be braked or steered .
D uring fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic and weather condit ions. ESC can­
not override the vehicle's physical limits, in­
crease the availab le tract ion, or keep a ve hicle
on the road if road departure is a result of
driver inattent io n. Instead, ESC imp roves the
poss ibil ity of keeping the vehi cle under con ­
trol and on the road during extreme maneu­
vers by using the d river's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
ca uses you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.

ESC includes and/or works together with the
anti-lock brake system (ABS), brake assist sys ­
tem, anti -slip regulation (ASR) , e lectronic dif­
ferential lock (EDL), dynamic steering* and electronic i nteraxle differential lock* /selective
wheel torque control* . ESC is switched on all
the t ime. I n certain s ituations when you need
less traction, you can switch
off ASR by press­
i ng the button~~
page 188, fig. 174 or
~ page 188, fig. 175. Be sure to sw itch ASR
on again when you no longer need less trac­
tion.
Anti-lock b ra king s ystem (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even d uring hard brak ing . Apply ste ady p res­
sure to the brake pedal. Do not pump the ped­
a l. A pulsing in the brake peda l indicates t hat
the system is he lping you to brake the vehicle .
Brake assist system
The brake assist system can decrease bra king
d istance. It increases braking power when the
d river presses the brake pedal quick ly in eme r­
gency situations . You must press and hold the
brake peda l until the situation is over. In
veh icles w ith adaptive cru ise contro l*, the
brake assist system is more sensit ive if the
d istance detected to the veh icle ahead is too
small.
Anti- slip regulati on (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills.
Elect ronic diffe renti al lo ck (EDL )
The ED L brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or wheels if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL automatica lly switches
off to help keep the brake on the braked whee l
from overheating. EDL w ill switch on again au-
Intellig ent technolog y 187
tomat ica lly when conditions have returned to
norma l.
Dynamic steering*
On vehicles with dynam ic steering*, ESC helps
stab il ize the s teer ing in crit ica l sit uat io ns.
Electronic interaxle differential lock* /
selective wheel torque control*
T he electronic i nteraxle differential lock (front
whee l dr ive) or the se lective whee l to rque
control (all-whee l dr ive) opera tes when dr iv­
ing thro ugh curves. The front wheel on the in­
side of the c urve or both whee ls on the inside
of the curve are braked selectively as needed .
This min imizes sliding in the front wheels and
allows for more precise driving through
cu rves . The applicable system may not acti­
vate when dr iv ing in wet or snowy conditions.
A WARNING
- ESC, ABS , ASR, EDL dynam ic steering*
a nd the elect ronic interaxle differential
loc k* /se lective wheel torque control*
cannot overcome the laws of physics .
This is especially important on slippery
or wet roads. If the systems begin acting
to stabilize your veh icle, yo u should im­
mediately change your speed to match
the road and traff ic conditions. Do not
let the increased safety provided by
these systems tempt you to take r isks.
Doing so will increase the risk of a loss of
veh icle contro l, col lision and ser ious per­
sonal injuries.
- Always adapt your speed to road, traffi c
and wea ther conditions. The risk of los­
ing con tro l of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead. ESC, ABS, the brake ass ist sys­
tem, ASR, EDL dynam ic steering* and the
electronic interaxle differentia l lock*/se­
lective whee l torque control* cannot p re-
vent co llisions . ..,.

188 Intelligent technology
-Always accelerate with special care on
even, smooth surfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these assistance systems that cannot al­
ways help to reduce the risk of loss of ve­ hicle control.
(i_) Tips
-ABS and ASR only work correctly when
all four wheels are equipped with identi-
Switching on/off
cal tires. Different tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems
described are working.
- If the indicator light
bl or t!lJ (USA
models)/[IJ (Canada models) appears,
there may be a malfunction

The ESC is designed to function in levels. De­
pending on the level that is selected, the sta­
bilization function of the ESC is limited or
switched off. The amount of stabilization con­
trol will differ depending on the level.
The following situations are exceptions where
it may be useful to switch on sport mode (Se­
