2013 AUDI S4 fuel cap

220 Checking and filling
-To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood .
- Keep children away from the engine com ­
partment .
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant could spray out.
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames. Fluids in the engine com­ partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running:
- First, fully apply the parking brake,
move selector lever of automatic trans- mission to
"P" (Park); put manual
transmission in Neutral.
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts . Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine .
- Minimize exposure to emission and
chemical hazards

A WARNING
=
California Proposition 65 Warning:
- Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth de­
fects and reproductive harm. In addition,
certain fluids contained in vehicles and
certain products of component wear con­
tain or emit chemicals known to the
State of California to cause cancer and
birth defects or other reproductive harm.
- Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive harms. Wash hands after handling.
(D Note
When adding fluids, always make sure that
they are poured into the proper container
or filler opening, otherwise serious dam ­
age to vehicle systems will occur.
@) For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly. If
you see spots from oil or other vehicle flu­ ids, have your vehicle inspected by an au­
thorized Audi dealer.

-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .
(D Note
Please note that summe r and wi nte r tires
are designed for the cond itions that are
Glossary of tire and loading terminology
Accessory weight means the comb ined weight (in excess of
those sta ndard items which may be rep laced)
of au toma tic transmission, power steer ing ,
power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are availab le as factory-installed equip­
ment (whether installed or not) .
Aspect ratio
means the rat io o f the height to the w idth of
the tire in percent . Numbers of 55 or lower in ­
dicate a low sidewall for improved steering re­
sponse and better overa ll handling on dry
pavement .
Bead
means the part of the t ire t hat is made o f
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the r im.
Bead separation
means a b reakdown of the bond between
components in the bead .
Cord means the strands forming the plies in the
tire.
Tire s an d wheel s 235
typica l in those seasons . Aud i recommends
using winter tires during the winter
months . Low temperatures signif icant ly
dec rease the e lasticity of summer t ires,
which affects tract ion and brak ing ability.
If summer t ires are used i n very co ld tem ­
peratures, cracks ca n form o n the tread
bars , res ulting in perma nen t tire damage
that can cause loud driving noise and un­
bala nced ti re s. Audi i s not respon sible for
th is type of damage .
Cold tire inflation pressure
means the t ire p ress ure recommended by t he
vehicle manufacture r fo r a tire o f a des ignated
s ize t hat has not bee n driven for more than a
coup le o f miles (k ilometers) at low speeds in
the three hour period before the tire press ure
is m easured or adjusted.
Curb weight
me ans the we ight of a motor ve hicle with
st andard equipmen t incl ud ing the max imum
capacity of fuel, oi l, and coolant, air condi ­
tioning and additional weig ht of optiona l
equipment.
Extra load tire
means a t ire design to oper ate a t higher load s
and at higher inflation pressures than the cor­
responding standa rd tire . Extra load tires may
be identified as "XL", "x l", "EXTRA LOAD", o r
"RF" on the sidewal l.
Gross Axle Weight Rating ("GAWR")
me ans the load-ca rry ing capac ity of a single
axle system , measured at the tire -ground in­
te rfaces.
Gross Vehicle Weight Rating ( "GVWR ")
mea ns the maximum total loaded we ight of
the ve hicl e. .,..

24 2 T ire s and wheel s
-Adjust the tire pressure to the load you are
carrying.
- Reinsta ll the va lve stem cap on the valve .
When should I check the tire pres sur e?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and a lways before starting a journey. Do not
forget to check the tire pressure for the spare
wheel.
When should I a dju st the tire p re ss ures?
Adjust the tire pressure to the load you are
carry ing . After changing a wheel
o r replacing
wheels you have to adjust the tire pressures
on all wheels . In addition, you must then initi­
alize the new tire pressures in the tire pres­
sure monitoring system*
r:!> page 253.
A WARNING
Incorrect tire pressures and/or underinf la­
tion can lead sudden tire failure, loss of
control, collision, ser ious personal injury
or even death.
- When the
II] warning symbol appears in
the instrument cluster, stop and inspect
the tires .
- Incorrect tire pressure and/or underinfla­
t ion can cause increased t ire wear and
can affect the handling of the veh icle and
stopp ing ability.
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fa il­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
- The driver is responsible for the correct
t ire press ures fo r all tires on the vehicle .
T he applicable p ressure va lues are locat­
ed on a sticker on the driver's side B -pil ­
lar.
- Only when a ll ti res on the vehicle are fi l­
led to the correct pressure, the tire pres­
sure monitoring system* can work cor­
rect ly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver observe the specified t
ire pressure val ues
for the tires and the correct pressures for
the function of the ti re pressure monitor­ing system*.
- Always inflate tires to the recommended
and correct t ire pressure before dr iv ing
off.
- Driving with underinflated tires bend
more, letting them get too hot resulting
in tread separation, sudden tire failure
and loss of control.
- Excessive speed and/overloading can
cause heat build-up, sudden tire failure
and loss of cont rol.
- If the tire pressure is too low or too high,
the t ires will wear prematurely and the
veh icle w ill not ha ndle well.
- If the tire is not flat and you do not have
to change a wh eel immediately, drive at
red uced speed to the nearest service sta­
tion to check the t ire p ressure and add
air as required.
Q) Note
D riving without valve stem caps can cause
damage to the tire valves. To prevent this,
a lways make sure tha t factory insta lled
valve stem caps on all whee ls are sec urely
mounted on the valve.
@ For the sake of the environment
U nderinflated tires w ill also incre ase the
fuel consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any tire can carry.
A vehicle that is over loaded will not handle
well and is more d iff icult to stop. Overloading
can not only lead to loss of vehicle control,
but can also damage important parts of the
vehicle and can lead to sudden tire fa ilure, in­
cl ud ing a b lowout and sudden deflation tha t
can cause the vehicle to crash.
Your safety and that of your passengers also depends on making sure that load limits are .,..
