ESP AUDI S4 2014 Repair Manual

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

202 Trailer towing
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the cold tire pressure listed under
"Full load" on the label located on the driver's
side B-pillar (visible when the door is open).
Inflate trailer tires to trailer and tire manufac ­
turers' specifications.
Lights
The headlight settings should be checked with
the trailer attached before driving off. Check
to make sure both vehicle and trailer lights
are working properly.
Safety chains
Be sure trailer safety chains are properly con­
nected from the trailer to the hitch on the ve­
hicle. Leave enough slack in the chains to per­
mit turning corners. When you install safety
chains, make sure they will not drag on the road when you are driving.
The chains should cross under the trailer
tongue to prevent it from dropping in case of
separation from the hitch.
Driving instructions
Driving with a trailer always requires extra
care and consideration.
To obtain the best possible handling of vehicle
and trailer, please note the following:
.,. Do not tow a loaded trailer when your car it­
self is not loaded.
.,. Be especially careful when passing other
vehicles.
.,. Observe speed limits .
.,. Do not drive at the maximum permissible
speed.
.,. Always apply brakes early.
.,. Monitor the temperature gauge.
Weight distribution
Towing a loaded trailer with an empty car re­
sults in a highly unstable distribution of
weight . If this cannot be avoided, drive at very
low speeds only to avoid the risk of losing
steering control. A "balanced" rig is easier
to operate and con­
trol. This means that the tow vehicle should be loaded to the extent possible and permissi­
ble, while keeping the trailer as light as possi­
ble under the circumstances. Whenever possi­
ble, transfer some cargo to the luggage com ­
partment of the tow vehicle while observing
tongue load requirements and vehicle loading
considerations.
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed. Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -particularly
when going downhill.
Reduce vehicle speed
immediately if the trail­
er shows the slightest sign of swaying .
Do not
try to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds
for vehicles towing trailers are lower than for
regular vehicles .
Always apply brakes early. When driving downhill, shift into a lower gear to use the en ­
gine braking effect to slow the vehicle . Use of
the brakes alone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge c> page 10
must be observed carefully . If the needle
moves close to the upper end of the scale, re­
duce speed immediately and/or turn off the
air conditioner.
If the coolant temperature warning light •
in the instrument cluster starts flashing, pull
off the road, stop and let the engine
idle for
about two minutes to prevent heat build-up .
_& WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not properly wearing the restraints
provided by Audi.

Trailer towing tips
Important to know
Your vehicle hand les different ly when tow ing
a trailer because o f the addit ional weight and
d iffe ren t weight distribution . Safety, perform ­
ance and economy w ill greatly depend on how
caref ully you load your trailer and operate
your rig.
B efore you actua lly tow your trailer, pr actice
turning, stopp ing and bac king up in an area
away from traffic. Keep practicing until you have become comp lete ly fam iliar with the way
your veh icle-trailer comb ination behaves and
responds.
Backing up is d ifficu lt a nd requires practice .
Backing up with a tra iler genera lly requires
steer ing action opposite to that when backing
up your vehicle without a trailer.
M aintain a g reater distance betwee n your ve­
h icle and the one in front o f you . You will need
mo re room to stop. To compensate for the
trailer, you will need a larger than normal
turning radius .
W hen pass ing, remember that yo u cannot ac ­
celerate as fast as yo u normally wo uld be­
cause of the added load. Make sure you have
e nough room to pass . After passing , allow
p lenty o f room fo r your tra iler before chang­
in g la nes aga in .
Avoid jerky starts, sharp turns or rap id lane
changes.
(D Tips
- Do not tow a tra iler during the break-in
period of you r vehicle.
- If you tow a trailer, your A udi may re­
quire more frequent maintenance due to
the extra load
o page 275.
Trailer towin g 203
Parking on a slope
Do not park on a slope with a trailer . If it can­
not be avoided, do so only after doing the fol­ lowing:
When parking:
.. App ly the foot brake.
.. Have someone p lace chocks under both the
veh icle and the tra iler wheels .
.,. With chocks in place, slowly release t he
bra kes unt il t he whee l chocks absorb the
load .
.. Tu rn the whee ls towards the curb.
.,. App ly the par king b rake .
.. Place an a utomatic transm ission* in P, re ­
spectively a manual transmission in first or
reverse gear.
When restarting after parking:
.,. App ly th e foot br ake .
.. Start the en gine.
.. Move the selector lever to D/S, respect ively
a man ual transmiss ion in first gea r.
.. Release the parking bra ke and s low ly pull
out and away from the wheel chocks .
.. Stop and have someone retr ieve the wheel
chocks.
@ Tips
If you move the selector leve r of the auto­
matic transmissio n* to P before applying
the pa rking brake and before blocking the
whee ls, you may hav e to use mor e forc e
l ater to move the le ver out of the P posi­
tion.

210 Fuel supply and filling your fuel tank
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
especially well for winter or summer driving. During seasonal change-over, we suggest that
you fill up at busy gas stations where the sea­
sonal adjustment is more likely to be made in
time.
CD Note
- Fuels containing a high percentage of
ethanol such as ESO and E85 may only be used in vehicles with flexible fuel en­
gines. Using high ethanol fuel in vehicles not equipped with flexible fuel engines
can cause severe engine damage.
- Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­ nents in the fuel system.
- Do not use fuels that fail to meet the
specified criteria in this chapter .
- If you are unable to determine whether
or not a particular fuel blend meets the
specifications, ask your service station or
its fuel supplier.
- Do not use fuel for which the contents
cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility of Audi and are not
covered under the New Vehicle or the
Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­
lems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Ethanol fuel (Bio -ethanol)
App lies to vehicles: with flexible fuel e ngi ne
You con recognize vehicles with a flexible fuel
engine by looking at the label on the inside of the fuel filler flap.
Vehicles with flexible fuel engines may be op­
erated with bio-ethanol fuels such as E85 (8S% ethanol and
15% gasoline) or with un­
leaded gasoline (91 AKI/ROZ 95). The vehicle
may also be operated with a mixture of these
fuels.
Your fuel consumption will increase when us­
ing bio-ethanol fuels due to the lower amount
of energy contained per unit volume in etha­
nol.
Warming up the flexible fuel engine in low temperatures
Due to the chemical composition of bio-etha­
nol, a certain amount of fuel ends up in the
engine oil when driving short distances in very
low temperatures . This fuel evaporates again
when the engine is warmed up.
II Please warm up engine.
If the driver message appears in the instru­
ment cluster display, drive with a warm en­
gine to reduce the oil level.
CD Note
- Never fill with methanol or with a higher
percentage of bio-ethanol than 85%
(E85). A higher percentage of bio-etha­
nol in the fuel can cause damage to the
engine or to the fuel system.
- If you use only E85, it is recommended
to fill the fuel tank completely with un­
leaded premium grade gasoline every
5,000 miles.
- If you experience starting, rough idle or
hesitation driveability problems, fill the
fuel tank completely with unleaded pre­ mium grade gasoline and drive it nor­
mally until the gasoline is used. See your
authorized Audi dealer if the problem
persists.
- Inform your authorized Audi dealer that
you are operating or have operated the
vehicle with E85.
- Read and follow the information and tips
about gasoline
