2013 AUDI S4 SEDAN light

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

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 .

r::> page 199.
Fabrics and fabric coverings
Fa brics and fabric coverings (e.g. seats, door
trim panels, etc.) should be cleaned at regular
intervals with a vacuum cleaner. This removes
surface dirt particles which could become em­ bedded in the fabr ic through use. Steam
cleaners should not be used, because the
steam tends to push the dirt deeper into the
fabric and lock it there.
Cleaning and protection 205
Normal cleaning
Generally, we recommend using a soft sponge
or a lint -free microfiber cloth to the clean fab­
ric. Brushes shou ld only be used for carpets
and floor mats, since other fabric surfaces
could be harmed by brushes.
Normal sur face stains can be cleaned using a
commercially available foam cleaner . Spread
the foam on the s urface of the fabric with a
soft sponge and work it in gently. Do not satu­
rate the fabric. Then pat the foam dry using
absorbent, dry cloths (e.g. m icrofiber cloth)
and vacuum it after it has dried completely.
Cleaning stains
Stains caused by beverages (e.g. coffee, fr uit
jui ce, etc.) can be treated with a mild deter­
gent solution. Apply the detergent solution
with a sponge. In the case of stubborn stains,
a detergent paste can be applied directly to
the stain and worked into the fabric. After­
wards, use copious amounts of clean water to
remove the remaining deterge nt. Apply the
water with a damp cloth or sponge and pat
the fabric dry with an absorbent, dry cloth.
Stains from choco late or makeup should have
detergent paste rubbed into them. After­
wards, remove the soap with water (damp
sponge).
Alcohol can be used to treat stains from
grease, oil , lipstick or a ballpoint pen. Melted
grease or dye must be patted off using ab­
sorbent materia l.
It may be necessary to re ­
treat the areas with detergent paste and wa­
ter.
In the case of genera l soiling of the upho ls­
tery and cover material, we recommend hiring
a specia list t hat has the equipment to clean
the seat covers and other fabr ic surfaces by
shampooing and spray extraction.
