fuel cap AUDI A5 COUPE 2010 User Guide

Fuel supply and filling your fuel tank Refuelling procedure
- Insert the fuel nozzle from the gasoline pump into the
fuel filler neck as far as it will go.
- Select a medium refuelling rate so that the nozzle switches off automatically when the tank is full.
Putting the fuel cap back on
- After filling your tank, twist the fuel cap clockwise as far
as it will go.
- Close the fuel filler flap.
To avoid fuel spilling or evaporating from the fuel tank always close
fuel cap properly and completely.
& WARNING
Improper refueling or handling of fuel can cause fire, explosion
and severe burns.
• Fuel is highly flammable and can cause severe burns and other
injuries.
• Failure to shut the engine off while refueling and/or to insert
the pump nozzle fully into the fuel filler neck could cause fuel to
spray out of filler neck or to overflow. Fuel spray and overflowing
fuel can cause a fire.
• Never use a cellular telephone while refueling. The electromag­
netic radiation can cause sparks that can ignite fuel vapors and
cause a fire.
• Never get back into your vehicle while refueling. If in excep­
tional circumstances you must get back in your vehicle while refu­ eling, make certain that you close the door and touch metal to
discharge static electricity before touching the filler nozzle again.
Static electricity can cause sparks that can ignite fuel vapors
released during refueling.
& WARNING (continued)
• Never smoke or have an open flame anywhere in or near your
vehicle when refueling or filling a portable fuel container.
• For your safety, we strongly recommend that you do not travel
with a portable fuel container in your vehicle. The container, full or
empty may leak and could cause a fire, especially in a crash.
• If, under exceptional circumstances, you must transport a
portable fuel container, please observe the following:
-Never fill a portable fuel container while it is anywhere in or
on the vehicle (for example, in the luggage compartment, or on
the trunk). Static electricity can build up while filling and can
ignite fuel vapors causing a fire.
- Always place a portable fuel container on the ground before
filling.
- Always keep the filler nozzle completely inside the portable
container before and during filling.
- If filling a portable container made of metal, the filler nozzle
must always be in contact with the container. This will help
prevent static electricity from discharging and cause a fire.
- Never spill fuel inside the vehicle or luggage compartment. Fuel vapors are highly flammable .
- Always observe local and state/provincial laws regarding the
use, storage and transportation of fuel containers.
- Make certain the fuel container meets industry standards
(ANSI / ASTM F852-86l.
0 Note
If any fuel has spilled onto the car, it should be removed immedi -
ately to prevent damage to the paint. _.,

<£> For the sake of the environment
As soon as the correctly operated nozzle switches off automatically
for the first time, the tank is full. Do not try to add more fuel because
fuel may spill out. In addition, the expansion space in the fuel tank
will be filled -causing the fuel to overflow when it becomes warm
and pollute the environment.
[ i] Tips
• Running your engine while refuelling may cause vapors to
escape or even cause fuel to spill out of the tank. This would then
shut off the fuel nozzle before the tank is full.
• Do not refuel your vehicle with the ignition turned on. The fuel
gauge may otherwise not indicate the correct fuel level after refuel ­
ling .
• The fuel filler flap of your vehicle is not locked when you lock the
vehicle from the inside .•
Unlocking the fuel filler flap by hand
You can open the fuel filler flap by hand if the power
locking system should fail.

Driving with an insufficient oil level is likely to cause severe damage
to the engine.
[ i] Tips
• The oil pressure warning display~ is not an indicator of the oil
level. Do not rely on it. Instead, check the oil level in your engine at
regular intervals, preferably each time you refuel, and always before
going on a long trip.
• If you have the impression your engine consumes excessive
amounts of oil, we recommend that you consult an authorized Audi
dealer to have the cause of your concern properly diagnosed. Keep
in mind that the accurate measurement of oil consumption requires
great care and may take some time. An authorized Audi dealer has
instructions about how to measure oil consumption accurately. •
Checking the engine oil level
Read oil level
Fig. 223 MMI Display;
Oil level indicator
Select: Function button [CARI> Oil level.
- Park your vehicle so that it is horizontally level. Shut
the engine off when it is at operating temperature.
Wait approx. two minutes. Read the oil level in the MMI* Display=> fig. 223. Add
engine oil if the bar of the oil level indicator is near "Min"
=>
page 275
Depending on the way the vehicle is driven and the operating condi­
tions, oil consumption can be up to a 1/2 quart per 600 miles (0.5
liter per 1000 kml. Consumption may be higher within the first 3000
miles (5000 kml.
[ i] Tips
The oil level indicator in the MMI* Display is only an information
display. If the oil level is too low, a minimum oil warning appears in
the instrument cluster. Add oil
=> page 275. If the hood has been
opened, the current oil level is shown in the instrument cluster the
next time the ignition is switched on. •

crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
low speed.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power steering,
power brakes, power windows, power seats, radio, and heater, to
the extent that these items are available as factory-installed equip­
ment (whether installed or not).
Aspect ratio means the ratio of the height to the width of the tire in percent.
Numb ers of 55 or lower indicate a low sidewall for improved
steering response and better overall handling on dry pavement.
Bead
means the part of the tire that is made of steel wires, wrapped or reinforced by ply cords and that is shaped to fit the rim.
Bead separation means a breakdown of the bond between components in the bead.
Cord
means the strands forming the plies in the tire.
& WARNING (continued)
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
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 driving, always stop as soon as it is safe to do so and check
the wheels and tires for damage . •
Cold tire inflation pressure
means the tire pressure recommended by the vehicle manufacturer
for a tire of a designated size that has not been driven for more than
a couple of miles (kilometers) at low speeds in the three hour period
before the tire pressure is measured or adjusted.
Curb weight means the weight of a motor vehicle with standard equipment
including the maximum capacity of fuel, oil, and coolant, air condi­
tioning and additional weight of optional equipment.
Extra load tire
means a tire design to operate at higher loads and at higher infla ­
tion pressures than the corresponding standard tire. Extra load tires
may be identified as "XL",
"xi", "EXTRA LOAD", or "RF" on the side ­
wall.
Gross Axle Weight Rating ("GAWR")
means the load-carrying capacity of a single axle system, measured
at the tire -ground interfaces.
Gross Vehicle Weight Rating ("GVWR"l
means the maximum total loaded weight of the vehicle.

Sidewall
means that portion of a tire between the tread and bead.
Speed rating means the speed at which a tire is designed to be driven for
extended periods of time. The ratings range from 93 mph (150 km/h)
to 186 mph (298 km/h)=>
page 300. You may not find this informa ­
tion on a ll tires because it is not required by law.
The speed rating letter code, where applicable, is molded on the tire sidewa ll and indicates the maximum perm issible road speeds=>
&
in "Winter tires" on page 304.
Tire pressure monitoring system*
means a system that detects when one or more of a vehicle 's tires
are under inflated and illuminates a low tire pressure warning te ll­
tale.
Tread
means that portion of a tire that comes into contact with the road.
Tread separation
means pu lling away of the tread from the tire carcass.
Treadwear indicators (TWI)
means the projections within the principa l grooves designed to give
a visual indication of the degrees of wear of the tread . See
=>
page 297, "Tread Wear Indicator (TWI)" for more information on
measuring tire wear.
Uniform Tire Quality Grading
is a tire information system developed by the United States National
Highway Traffic Safety Adm inistration (NHTSA) that is designed to
help buyers make relative comparisons among tires. The UTQG is
not a safety rati ng and not a guarantee that a tire will last for a
prescribed number of miles (kilometers) or perform in a certain way.
It simply gives tire buyers additional informat ion to combine with
other considerations, such as price, brand loyalty and dealer recom-mendations. Under UTQG, tires are graded by the tire manufac­
t urers in three areas: treadwear, traction, and temperature resis­
tance . The UTQG information on the tires, molded into the
sidewalls.
U .S. DOT Tire Identification Number (TIN }
This is the tire's "seria l number". It begins with the letters "DOT"
and indicates that the tire meets al l federa l standards. The next two
numbers or letters indicate the plant where it was manufactured,
and the last four numbers represent the week and year of manufac­
ture. For example,
DOT ... 2209 ...
means that the tire was produced in the 22nd week of 2009 . The
other numbers are marketing codes that may or may not be used by
the tire manufacturer . This information is used to contact
consumers if a tire defect requires a reca ll.
Vehicle capacity weight
means the rated cargo and luggage load plus 150 lbs. (68 kilograms)
times the vehicle's tota l seating capacity as listed on the label
located either on the driver's side 8-pillar or on the inside of the fuel
filler flap.
Vehicle maximum load on the tire
means that load on an individual tire that is determined by distrib­
uting to each axle its share of the maximum loaded vehicle weight
and dividing by two.
Vehicle normal load on the tire
means that load on an individual tire that is determined by distrib­
uting to each axle its share of the curb weight, accessory weight,
and normal occupant weight (distributed in accordance with table
below =>
page 291) and dividing by two. _..

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.
Fig. 229 Tire pressure
label: located either on
driver's side B-pillar or
inside the fuel filler flap
Tir e pressure generally refers to the amount of air in a tire that it
needs it to do its job and safely carry the combined load of the entire
vehicle and its contents. T ire pressure is measured in kilopascals
(kPa), the international measuring unit and in pounds per square
inch (PSll. Tire pressure is based in part on the vehicle's design and
load limit -the greatest amount of weight that the vehicle can carry
safely and the tire size . The proper tire pressure is frequently
referred to as the "recommended cold tire inflation pressure." Air in
the tires expands when the tire heats up because of internal friction
when it flexes in use. The tire pressure is higher when the tire has
warmed up than when it is "cold." It is the inflation pressure in a
"cold" tire that counts. Therefore, you should never let air out of a
warm tire to match "cold tire inflation pressure" recommendations.
The tires would then be underinflated and could fail suddenly.

Main taining proper tire pressure is one of the most important
things you can do to help avoid sudden tire failure. Underinflated
tires are a major cause of sudden tire failure. Keeping tires at the
right pressure is also important for safe and responsive vehicle
handling, traction, braking and load carrying.
Tire pressures are
particularly important when the vehicle is being driven at higher
speeds, and then especially when heavily loaded even within the
permissible load-carrying capacities approved for your vehicle.
The recommended tire pressures for your Audi depend on the kind
of tires on your vehicle and the number of passengers and/or
amount of luggage you will be transporting.
On USA vehicles, the tire pressure label is located on the driver's
side B-pillar. On Canada vehicles, the tire pressure label is located
either on the driver's side B-pillar or inside the fuel filler flap . The tire
pressure label lists the recommended cold tire inflation pressures ..,.

The tire pressure label on your Audi lists the recommended cold tire
in flation pressures at maximum capacity for the new, origina l equip ­
ment tires that were on your vehicle at the time it was manufac­
tured. For the location of the label
~ page 291, fig. 229 .
Most tires lose air natural ly over time. They can a lso lose some air if
you drive over a pothole or hit a curb while parking. It is usually not
possible to see whether the radial t ires used today are underinflated
just by looking at them.
Therefore, be sure to check tire pressures at least once a month and always before going on a long trip. Make sure to take the number of
people and the amount of luggage into account when adjusting tire
pressure for a trip - even one that you would not consider to be
"long ." See ~
page 295, "Tires and vehicle load limits" for more
important information .
Always use an accurate tire pressure gauge when checking and adjusting inflation pressures. Check a ll of the tires and be sure not
to forget the spare tire . If the pressure in any tire is too high when
the tire is "cold," let air out of the tire s lowly with the edge of the tire
gauge and keep checking the pressure until you reach the pressure
that is correct for the load (passengers and luggage) and kind of
driving you p lan to do.
If the pressure in any tire is too low, note the difference between the
press ure in the cold t ire and the pressure you need and add the air
that you need to reach the correct pressure for the vehicle load
(passengers and luggage) for the tires on your vehicle as listed on
the on your vehicle and in this manual and the kind of driving you p lan to do .
Nev er e xce ed the m aximum i nflation pr essure listed on the tir e
s ide wall for any re aso n .
Reme mber that the veh ic le manufacturer, not the tire manufacturer,
determines the correct tire pressure for the tires on your vehicle .
It is important to check the tire pressure when the tires are cold.
• Read the required tire pressure from the tire pressure label. On
USA vehicles, the tire pressure label is located on the driver's side 8-pillar
. On Canada vehicles , the tire pressure label is located either
on the driver's side B -pi llar or inside the fuel fi ller flap . The ti re pres ­
sure labe l lists the recommended co ld tire inflation pressures for
the vehicle at its maximum capacity weight and the tires that were
on your vehicle at the time it was manufactured . For recommended
tire p ressu res for normal load conditions, please see chapter
=> page 291.
• Turn the va lve stem cap counte r-clockwise to remove it from the
tire valve.
• Place the air pressure gauge on the valve.
• T he tire pressures should only be checked and adjusted when
the tires are co ld . The s lightly raised pressures of warm tires must
not be reduced .
• Adjust the tire pressure to the load you are carrying.
• Reinstal l the valve stem cap on the valve.
Wh en should I ch ec k th e tir e pr ess ure?
The correct tire pressure is especially important 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 pres ­
sure for the spare wheel.
When should I adjust the tire p res sure s?
Adjust the tire pressure to the load you are carrying . After changing
a wheel
or replacing whee ls you have to adjust the tire pressu res on
a ll wheels . In addition, you must then initialize the new t ire pres­
sures in the tire pressure monitoring system*~

& WARNING (continu ed )
• Incorrect tire pressure and /or under inflation can cause
in creased tire wear and can affect the handling of the vehicle and
stopping ability .
• Incorrect t ire pressures and /o r underinflat ion can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing lo ss of vehicle control .
• The driver is respon sible for the correct tire pressures for all
tires on the vehicle. The applicable pre ssure values are located on
a sticker on the driver 's side 8-pillar or on the inside of the fuel
filler flap .
• Only when all tires on the vehicle are filled to the correct pres ­
sure , the tire pressure monitoring system * can work correctly .
• The use of incorrect tire pressure values can lead to accidents
or other damage . Therefore it is essential that the driver observe
the specified tire pressure value s for the tires and the correct pres ­
sures for the function of the tire pressure monitoring system *.
• Always inflate tires to the re commended and correct tire pres ­
sure before driving off .
• Driving with underinflated tires bend more , letting them get
too hot resulting in tread separation , sudden tire failure and loss
of control.
• Ex cessive speed and /overloading can cause heat build-up ,
s udden tire failure and lo ss of control .
• If the tire pres sure is too low or too high , the t ires will wear
prematurely and the vehicle will not handle well .
• If the tire is not flat and you do not have to change a wheel
immediately , drive at reduced speed to the nearest service station
to check the t ire pressure and add air as required.
