2014 AUDI S4 ESP

-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 .
-Always read and heed all WARNINGS whenever using a child restrained in ave­
hicle is being used¢

(D Note
If you leave the child restraint with the
tether strap firmly installed for severa l
days, this cou ld leave a mark on the up­
holstery on the seat cushion and backrest
in the area where the tether strap was in­
s t alled. The upho lstery would a lso be per­
manently stretched around the tethe r
s tr ap. This applies especially to leat her
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.

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 . ..,.

190 Intelligent technology
Operating conditions and d riving hab it s
The brakes on today 's automob iles are st ill
subject to wear, depending largely on operat ­
ing conditions and driving habits
c::> ,& . On
vehicles that are either driven mostly in stop­
and-go city traffic or are driven hard, the
brake pads should be checked by your author­
ized Audi dealer more often than specified in
the
W arranty & M ainte nance booklet . Failure
to have your brake pads inspected can result
in reduced b rake pe rformance.
On steep slopes, you should use the brak ing
effect of the eng ine . This way, you prevent un ­
necessa ry wear on the brake system. If you
must use you r brakes, do not hold the brakes
down continuously . P u mp the b rakes at inter­
va ls.
Operating nois e
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity .
Effect of w ater and ro ad sa lt
In certain situat ions, for example after driving
through wate r, in heavy ra in, after overn ight
condensation or after washing your car, the brak ing effect can be reduced by moistu re or
i ce on the bra ke roto rs and b rake pads . The
b rakes must be dried fi rst with a few ca ref ul
brake app lications .
At h igher speeds and with the w indshie ld w ip­
e rs turned on, the brake pads press agains t
the bra ke rotors for a short amount of time.
This occurs a t regular intervals without the
driver noticing and provides for better brake response time under wet conditions.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered
road and the brakes are not used. Likewise,
you clean off accumulated sa lt coating from
brake discs and pads with a few caut ious ap ­
plications of the brake
c::> ,& .
Cor rosion
There may be a tendency for dirt to bui ld up
on the brake pads and corrosion to form on the d
iscs if the car is not driven regu larly or
o n Ly for short trips with litt le use of the
brakes.
If t he brakes a re not used frequently, o r if cor­
r os ion has formed on the discs, it is adv isable
to clean off the pads and discs by braking
firmly a few times from a moderately h igh
speed
c::> .&. .
Fault s in the brak e syst em
If you shou ld notice a sudden increase in
brake pedal trave l, then one of the two brake
circuits may have fai led
c::> .& .
Low br ake fluid lev el
Malfunctions ca n occu r in the b ra ke system if
t h e b rake fluid level is too low. The brake flu id
l evel is monitored electronica lly.
Brake booster
The brake booster inc reases the pressure that
you generate with the b rake peda l. It works
o n ly when the engine is runn ing
.c::> .&
Brake lining wear status
Brake lining wear may be checked by visual in­
spect io n of the condition of the brake pads
th rough the open ings in the wheel. If neces­
sary, the wheel may be removed fo r thi s i n­
spe ct ion
c::> page 255, Changing a wheel.
.&, WARNING
- New b rake pads don' t have the bes t stop­
ping power and m ust be "bro ken -in" dur ­
ing the initial 100 to 150 miles (150 to
200 kilometers) of normal c ity driving.
You can compensate for this by pressing the brake pedal more firmly. Th is also
applies later when new pads are instal­
led.
- You shou ld perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Othe r road use rs must no t be put at risk -
you may ca use an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range. Do not ride
~

194 Intelligent technology
Plea se start the engin e soon or th e system
w ill be tu rned off.
The warning ind icates that the system will be
turned off automa tic ally after 3 m inu tes. If
you wish to continue using the functions , you
have to start the engine .
With the engine running
Although electrical e nergy is generated when
the vehicle is be ing driven , the battery can be­
come d ischarged. This happens most ly when
little energy is being generated and a great
deal consumed and the battery 's state of
charge is not optimal.
To br ing the energy balance back into equili­
brium, consumers which require especia lly
large amounts of energy are temporarily c ut
back or switched off. Heating systems in par·
ticular requ ire a great deal of energy. If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they have been temporar ily cut back or switched
off. These systems will be ava ilable again as
soon as the energy ba lance has been restored.
You will also notice that engine idle speed has been increased slightly . This is norma l and not
a cause fo r concern . By increas ing engine idle
speed the add itiona l ene rgy required is gener­
ated and the batte ry is charged.

Driving and
environment
The first 1
1000
miles
(11500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1 ,500 km) .
For the first 600 mile s (1,000
kilometers ):
.,. Do not use full throttle.
.,. Do not drive at engine speeds that are more
than 2/3 of the max imum permitted RPM .
From 600 to 1,000 mile s (1 ,000 to
1,500 kilometers ):
.. Speeds can gradually be increased to the
maximum perm iss ible road or eng ine speed .
During and after br eak-in period
.. Do not rev the engine up to h igh speeds
when it is cold. Th is applies whether the
transmission is in N (Neutral) or in gear.
After the break- in peri od
.. Do not exceed max imum eng ine speed un­
der any circumstances .
.. Upshift into the next higher gear before
reaching the red area at the end of the tach­
ometer scale c.>page 10.
During the first few hours of driving, the en­
g ine's internal friction is higher than later
when all the moving parts have been broken
in . How well this break -in process is done de ­
pends to a considerable extent on the way the
ve hicl e is driven du ring the first 1,000 miles
(1,500 kilome ters).
(D Note
Extremely h igh engine speeds are auto­
mat ica lly reduc ed. However, t hese rpm
lim its are programmed for a n engine well
r u n- in, not a new engine.
Driving and environment 195
@) For the sake of the environment
Do not drive with unnecessarily high en­
g ine speeds -upshifting ear ly saves f uel,
reduces noise and protects the environ­
ment.
New tires
If your vehicle is running on new tires, drive
very carefully for the first 350 miles (500 ki lo­
meters) after fitting.
.&, WARNING
N ew tires tend to be sl ippery and mus t al­
so be "b roken -in" . Be sure to remember
this dur ing the f irst 350 m iles (500 kilo­
meters) . Brake gently . Avoid fo llowing
closely behind other vehicles or other sit­
uations that m ight require sudden, hard
b raking .
Avoid damaging the
vehicle
When you are d rivi ng on poo r roads, or over
cu rbs, steep ramps, etc., make certa in that
low- ly in g parts s uch as spo ile rs and ex ha ust
system parts do not bottom o ut and get dam ­
aged.
Th is is espec ially true for veh icles with low­
s lung chassis (spo rts chas sis)* and fully load ­
ed vehicles.
Driving through water
on roads
Note the following to avoid ve hicle damage
when driving through water, for e xamp le on
flooded roads:
- The wa ter must not be any higher than the
bottom of the vehicle body .
- Do not dr ive faster than walk ing speed .

198 Driving and en vironm ent
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
.,. Shut the engine off when you are not dr iving
the vehicle.
.,. Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traffic
jams, when waiting for trains to pass at ra il­
road crossings, or at traff ic lights that have
l ong wa its on red . Turning the engine
off fo r
just 30-40 seconds saves more fue l than is
burned s tarti ng the eng ine again .
It takes a long time for the engine to warm up
fu lly when it is running at idle . Howeve r, wear
and nox ious em issions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights shou ld come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over­
heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
... Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
authorized Audi dealer he lps to ensure that it
runs properly and economically . The condition
of your vehicle not only affects its safety and
ab ility to hold its value, it also affects
fuel
consumpt ion .
Check you r oil ea ch time you fill you r tank.
The amount o f oi l used is re lated to engine
load and speed.
It i s normal fo r the oil consump tion of a new
engine to reach its lowest value after a certa in
mileage has been d riven.
You must drive your veh icle about 3,000 m iles
(S,000 kilometers) before you can properly
assess oil consumpt ion.
T his also app lies to fue l consumption and en­
gine o utput.
(D Note
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
& Main­
t enance boo klet . Lack of p roper ma inte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
-Do not alter or remove any device, such
as heat sh ie lds, switches, ign it ion w ires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avoid dr iv ing short distances w ith a
cold engine .
T he engine and cata lytic converter have to
reach their opt imal
operat ing temperature to
reduce fuel consumpt ion and nox ious emis­
s ions effectively .
Just after starting, a co ld eng ine in a mid-s ize
car only achieves a fuel economy of 6-8 m iles
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy cl imbs to 12 mpg
(20 l/100 km) . After about
2 .5 miles (4 km), ll>

the engine is at its proper operating tempera­
ture and fuel economy has reached a normal
level. So you can see that you should avoid
short trips whenever possib le.
The
outside temperature is also critical in this
regard. Your car consumes more fuel in the
winter than in the summer .
allroad: Driving offroad
General information
Applies to vehicles: atlroad
When driving offroad, the funct ions for the
e lectronic stab ilization control (ESC) are ex­
panded. The ESC-Offroad-Mode can be activat­
ed in driving situations in which a wheel lock
or a differentia l lock function is needed
c::> page 188. In addit ion, your Audi provides
continuous all wheel drive .
Your Audi is however , not an offroad vehicle.
Never drive the vehicle in terrain which is not
suitable for the vehicle, or which exceeds
your driving skills. Never take any unneces­
sary risks!
After driving offroad
-After driving offroad, remove branches and
other debris from the radiator grille, under ­
body, and wheels. Look especially for objects
(stones) that have been caught in the tire
tread .
- Clean the body and the vehicle underbody
and inspect the vehicle for possible damag­
es.
- Clean off the dirty windows, headlights, tail
lights and the license plate.
- Perform a brake test (especially after driving through water).
A WARNING
- Be espec ially aware and attentive when
dr iv ing under diff icult conditions . Dam­
ages to the vehicle and injuries may oc­
cur when driving at an excess ively high
speed or with incorrect driving maneu­
vers.
Driving and environment 199
- Always adjust your speed and handling
to the roads, terrain, traff ic and weather
conditions. Drive especially slow if off­ road with low visibility.
- Please note that the wheels can spin and
the vehicle can break away when the ESC
Offroad Mode is switched off, especially
when the road is slippery .
- Driving stability is reduced in the ESC
Offroad mode .
® For the sake of the environment
Avoid harming the environment and take
nature into cons ideration.
(D Tips
Only drive where it is allowed and always
stay on the provided roads and paths.
Driver messages
Applies to vehicles : a ll road
There is only one right way to drive in difficult
conditions: slowly and with caution!
When dr iving offroad, observe the following:
... Never drive the vehicle i n terrain which is
not suitab le for the vehicle, or which ex­
ceeds your driv ing ski lls. Never take any un­
necessary risks!
... Drive slow ly and cautiously!
... Pay attention to the
ground clearance of
your vehicle! This may vary depending on the load and composition of the ground and
the environment. The driver is therefore re­
sponsible for deciding whether a veh icle can
handle a specific situation.
... Act ivate the
ESC -Offroad-Mode c::> page 188
as needed.
Difficult terrain
Never dr ive in areas that are not familiar to
you and drive slowly when offroad and be pre­
pared and expect the unexpected (e.g. pot­
holes, boulders, tree stumps, etc.)
To prevent the vehicle from bottoming and avo id damage to the underbody, you should
drive straight across severe bumps in the
