2013 AUDI S4 SEDAN warning

A WARNING ,~ ~
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
store the full brak ing effect.
([) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv­
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine off when driving
th rough water.
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for you r vehi­
cle to drive th rough safely.
- Avoid dr iving through sa lt water because
i t can ca use corrosion.
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function ­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
11-Always use lead-free gasoline q page 210,
Fuel supply .
"'" Never run the tank down a ll the way to
empty.
11-Never put too much motor oil in your en-
gine
q page 220, ~ Adding engine oil .
11-Never try to push -or tow-start your veh icle .
The catalytic converter is an efficient "clean­ up" device built into the exhaust system of
the vehicle . The catalytic converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere .
Drivin g and en vironm ent 193
The exclusive use of unleaded fuel is critically
important for the life of the catalytic convert­
er and proper funct ion ing of the engine.
A WARNING
-
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other mate rial wh ich can
cause a fir e.
- Do not apply additional undercoating or rustp roof ing on or near the exhaust
manifold, exhaust pipes, catalytic con­
ve rter or heat shields. During driv ing, the
substance used for undercoating co uld
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fu el w il l already ser iously de­
gra de the performance of the catalytic
c onverte r.
- Do not ex ceed t he cor rect eng ine oil level
qpage 220.
- Do not drive until the fue l tank becomes
comple tely empty. The engine co uld m is­
fire . Unburned fuel could also get in to
the exhaust system and th is co uld cause
the catalytic converter to overheat .
- Do not turn off the ignition while the ve ­
hicle is moving.
- Do not continue to ope rate your veh icle
unde r these conditions, as otherwise fuel
can reach the catalytic converte r. T his
cou ld result in overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis ­
sion Control System:
- H ave you r vehicle maintained prope rly
and in accorda nce w ith the serv ice rec­
ommendat ions in yo ur Warranty &
M ain tenance boo klet.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle w ill impair
the function of the em ission contro l
system and could lead to damage . ..,. •

(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which could 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 serv iced at regular inter-
vals .
By having your vehicle regularly serviced by an
authori zed Audi dealer helps to ensure that it
runs properly and economically . The condition
of your vehicle not only affects its safety and
ab il ity to hold its value, it also affects
fuel
consumption.
Check your oil each time you fill your tank.
The amount of oil used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven.
You must drive your vehicle about 3 ,000 miles
(5,000 kilometers) before you can properly
assess oi l consumption.
This a lso applies to fuel consumption and en­
g ine output .
0 Note
-Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper mainte ­
nance as well as improper use of the ve­
hicle will impair the function of the
emission control system and could lead
to damage.
Driving and environment 195
- 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 shields, switches, ignition wires,
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 rela tively
high on short trips .
.,. Try to avoid driving short distances with a
cold engine.
The engine and cata lytic converter have to
reach their opt imal
operating temperature to
reduce fuel consumpt ion and noxious emis­
sions effectively .
Just after starting, a co ld engine in a mid-size
car only achieves a fuel economy of 6-8 miles
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy climbs to 12 mpg
(20 l/100 km) . After about
2 .5 miles (4 km),
the engine is at its proper operat ing tempera­
ture and fuel economy has reached a normal
level. So you can see that you should avoid
short trips whenever possible.
T he
outside temperature is also cr itical in th is
regard. Your car consumes more fue l in the
winter than in the summer.

196 Trailer towing
Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a trai ler, p lease remember
that the additional load will affect durability,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
For this reason, always fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
Trailer hitch Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­
ble for your vehicle and trailer and must be
mounted securely on the veh icle's chassis at a
technically sound location. Use only a trailer
hitch with a removable ball mount. Always
check with the trailer hitch manufacturer to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that
it does not interfere with the impact-absorb­
ing bumper system . No modifications should
be made to the vehicle exhaust and brake sys­
tems . From time to time, check that all hitch
mounting bolts remain securely fastened.
When you are not towing a trailer, remove the
trailer hitch ball mount. This prevents the
hitch from causing damage should your vehi­
cle be struck from behind
¢ A.
Trailer brakes
If your tra iler is equipped with a braking sys­
tem, check to be sure that it conforms to a ll
regulations . The trailer
hydraulic brake system must not be
direct ly connected to the vehicle's hydraulic
brake system
~ A.
Safety chains
Always use safety chains between your vehicle
and the trai le r.
Trailer lights
T railer lights must meet all regulations. Be
sure to check w ith your authorized Audi dealer
for correct wiring, sw itches, and relays.
Mirrors
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors . It is important
that you
always have clear vis io n to the rear.
,8. WARNING
- If a trailer has electrical brakes please
note that these brakes are not activated
by the factory-fitted control unit -risk of
accident!
- Afte r removing the trailer hitch, do not
store it in your vehicle. In case of sudden
braking, the hitch could fly forward and
injure you or your passengers.
Operating instructions
Maximum trailer weight
-
A trailer for your vehicle is limited to a typical
class 1 or class 2 tra iler.
Trailer load distribution Be sure the load in the trailer is held secure ly
in place to prevent it from shifting forward,
backward or sideways.
Never allow a passenger to ride in a trailer
¢ A in Driving instructions on page 197.
Engine cooling system
T owing a trailer makes the engine work hard ­
er. It is important that the cooling system's
performance is up to the additional load.
Make sure that the cooling system has enough
fluid . .,..

Tire pressure
When towing a trai le r, inflate the t ires of your
vehicle to the co ld tire pressure listed under
"Full load" on the label located on the driver's
side B-pillar (vis ible when the door is open).
Inflate trailer tires to trailer and tire manufac­
turers' specifications.
Light s
The headlight settings should be checked with
the trailer attached before driving off. Check
to make sure both vehicle and trai ler lights
are working properly.
Safety chains
Be su re tra iler sa fety 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 w ill not drag on the
road when you are driving.
The chains shou ld cross under the trai ler
tongue to prevent it from dropping in case of
separatio n from the hitch .
Driving instructions
Driving with a trailer always requires extra
core and consideration.
To obtain the best possible handling o f vehicle
and trai ler, p lease note the following:
.,. Do not tow a loaded trailer whe n your car it­
self is not loaded .
.,. Be especia lly careful when passing other
vehicles .
.,. Observe speed limits .
.,. Do not drive at the maximum permissible
speed .
.,. Always apply brakes ea rly .
.,. Monitor the temperature gauge.
Weight di stribution
Towing a loaded trai ler with an empty car re­
sults in a highly unstable distribution of
weight . If this cannot be avo ided, drive at very
low speeds only to avoid the risk of losing
steer ing control.
Trailer towing 197
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 keep ing the trailer as light as possi­
ble under the c ircumstances. Whenever poss i­
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 d iff icult 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 -pa rticularly
when going downhill.
Reduce veh icle speed
immediately if the trail­
er shows the slightest s ign of sway ing .
Do not
try to stop the swaying by accelerating.
Observe speed limits . In some areas, speeds
for vehicles tow ing tra ilers are lower than for
regular vehicles .
Always apply brakes early. When driving downh ill, 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 ¢ page 10
must be observed carefully . If the need le
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 .
A WARNING
Anyone not properly restrained in a mov ­
ing vehicle is at a much greater risk in an
accident . Never let anyone ride in yo ur car
who is not properly wearing the restraints
prov ided by Audi.

Cleaning and protect ion
General information
Regular core preserves vehicle value.
Any automobile is exposed to industrial
fumes , corrosive road salt, etc. A well cared
for Audi can look like new many years after
purchase . Regular and correct care w ill con­
tr ibute to maintaining the beauty and value of
your Aud i.
Furthermore, good care may be a condition
for substantiating a warranty claim should
corrosion damage or paint defects occur.
Your authorized Audi dealer has a variety of
dedicated vehicle-care products and can ad­
vise which ones to use for cleaning the exter i­
or and interior of your vehicle.
Whether you use products recommended by
Audi or other commercially available cleaning
agents, please make sure you apply them cor­
rectly .
.&, WARNING
-Cleaning agents may be poisonous. Keep
them out of the reach of children.
- Heed all caution labels.
- Always read directions on the container
before using any product. Follow the di­
rect ions carefully.
- Most chemical cleaners are concentrated
and have to be diluted .
- Use spot removing fluids only in well
ventilated areas.
- Do not use gasoline, kerosene, d iesel
fuel, nail polish remover or other volatile
fluids. They may be toxic, flammab le or
haza rdous in other ways. Do not wash,
wax or dry the vehicle with the ignition
on or the engine running.
- Do not clean the undersides of chassis,
fenders, wheel covers, e tc. without pro­
tecting your hands and arms. You may cut yourself on sharp-edged metal parts.
Cleaning and protection 199
-Moisture and ice on brakes may impair
brak ing effic iency¢
page 187. Test the
brakes carefully each time you wash the
veh icle.
@) For the sake of the environment
Select on ly environmentally friend ly clean­
i ng products . Leftover cleaning products
should not d isposed of in the household
waste.
Care of exterior
Washing
Frequent washing protects the vehicle .
The best protection against environmental i n­
fluences is
frequent washing and waxing . How
often th is is required depends on:
- How much the veh icle is used
- Where the veh icle is parked (garage, in the
open under trees, etc.)
- The seasonal and weather conditions
- Environmental influences
T he longer b ird droppings, insects, tree resin,
road and indus trial gr ime, tar, soot, road salt
and other materials remain on the vehicle
body, the more lasting their destructive ef­
fects will be . High temperatures caused by ex­
posure to intense sun light intens ify the corro­
sive effect, particularly when humid ity is high
as well.
Under certain circumstances,
weekly washing
may be necessary. Under other cond itions, a
monthly washing and waxing may be ade­
quate .
After the winter, the underside of the vehicle
should be thoroughly washed, preferab ly in a
professional car wash .

200 Cleaning and protec tio n
Automatic car wash
The vehicle can be washed in almost any
modern automatic car wash .
The vehicle paint is so durable that the vehicle
can normally be washed without problems in
an automatic car wash. However, the effect on
the paint depends to a large extent on the de­
sign of the facility, the filtering of the wash
water, the type of wash and care mater ial , etc.
I f the pa int has a dull appearance afte r going
through the car wash or is scratched, bring
this to the attention of the operator immedi­
ately.
If necessary, use a different car wash.
Before going through a car wash, be sure to
take the usual precautions such as closing the
windows and the roof . Factory installed an­
tennas must not be removed.
I f you have installed additional accessor ies on
the vehicle - such as spoilers, roof rack, etc. -
it is best to ask the car wash operator if these
should be removed .
A WARNING

In the interest of the environment, the ve­
hicle should only be washed in special
wash bays.
Washing your vehicle with a power
washer
Cleaning the ex terior of your car wi th a high­
pressure power washer is safe as long as you
observe a few simple rules .
11-Before using the power washer, make su re
you have read and understood the WARN­
INGS
c:::> A in General information on
page 199 .
11-Always fo llow the operating instructions for
the power washer .
11-Make sure that the jet on the spray hose
produces a "fan shaped spray".
11-Do not ho ld the spray nozzle too close to
soft materia ls.
When cleaning the vehicle with a power wash­
er
always fo llow the operating instructions .
This applies particularly to the
operati ng
p re ssu re
and the s p ra yin g distance . Maintain
a sufficient d istance to soft mater ials such as
rubber hoses and sound/vibra tion deadening
materials (particularly on the underside of the
engine hood) . Do not use a jet wh ich sprays
water in a
direct stream or one that has a ro·
tat in g
jet.
Water temperature should not exceed 140 °F
(60 °() .
A WARNING
Never wash tires w it h a jet that sprays wa­
t er in a direc t stream. This cou ld cause in ­
visib le damage to t he tires and weake n
them, even if the spray is from a relatively
long distance and for a short time . Dam­
aged and weakened t ires can fai l and cause
accidents and persona l injury.
(D Note
To avo id damag ing your vehicle, always
make sure t hat there is sufficient distance
Cleaning and protec tion 20 1
between the spray head and soft materia ls
like rubber hoses, plastic parts and sound­
deaden ing mater ia ls. Never aim the spray
head at the same point for a long time.
This also applies to cleaning headlights
and painted bumpers . Remember: the
closer the nozzle is to the surface of the
mater ia l, the greater the st ress on the ma­
terial.
Sensors and camera lenses
- Remove snow w ith a hand br ush and remove
ice with a de -icing sp ray that does not con­
tain so lvents.
- Clean the senso rs (adap tive c ruise co ntrol *,
parking system *) with a cleaning so lution
that does not contain so lvents and a soft
cloth.
(D Note
- If you wash your vehicle with a pressure
washer,
- make sure there is enough distance to
sensors i n the rear bumper.
- do not clean the camera lenses and the
area a ro und them with the press ure
washer.

202 Cleaning and protec tio n
paint extra p rotection, particularly if water no
longer beads on the clean paint.
P rotec t plastic body parts with ca r wax in the
same way as the vehicle body.
During warm weather dead insects tend to
collect on the front bumper and on the for­
ward area of the hood. They are much easier
to remove from paint that is waxed
often.
Poli shing
Polish your vehicle only if the paint has lost its
shine and the gloss cannot be brought back
with wax.
If the polish used does not contain preserva­
tive compounds, the paint must be waxed af­
terwards.
