2009 AUDI Q7 fuel cap

Fuel supply and filling your fuel tank
Blend of gasoline and ethanol (grain alcohol or ethyl alcohol}
• Anti-knock index must be 87 AKI or higher.
• Blend must not contain more than 10% ethanol.
Blend of gasoline and MTBE
• Anti-knock index must be 87 AKI or higher.
• Blend must contain not more than 15% MTBE.
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 seasonal adjustment
is more likely to be made in time.
0 Note
• Methanol fuels which do not meet these requirements may
cause corrosion and damage to plastic and rubber components 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 responsi ­
bility 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 problems due to the use of one of these fuel blends,
we recommend that you switch to unblended fuel. •
Gasoline additives
A major concern among many auto manufacturers is carbon
deposit build-up caused by the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another,
they have certain things in common. All gasoline grades contain
substances that can cause deposits to collect on vital engine parts,
such as fuel injectors and intake valves. Although most gasoline
brands include additives to keep engine and fuel systems clean,
they are not equally effective.
Audi recommends using TOP TIER Detergent Gasoline. For more
information on TOP TIER Detergent Gasoline, please go to the offi­
cial website (www.toptiergas.com).
After an extended period of using inadequate fuels, carbon deposit
build-ups can rob your engine of peak performance.
(D Note
Damage or malfunction due to poor fuel quality is not covered by
the Audi New Vehicle Limited Warranty. •

Your vehicle fuel tank has an on -board refuelling vapor recovery
sys tem. Th is feature helps to prevent fue l vapors from escapin g
from the tank and polluting the environment wh ile you refue l your
veh ic le . I n order to fill the tank properly while protecti ng the envi­
ronment, please follow this refuel ing procedure carefully .
& WARNING
Under normal operating conditions , never carry additional fuel
c ontainers in your car . Ga s canister s and other containers used to
transport fuel can be dangerous . Such conta iners , full or empty,
may leak and could cause a fire in a collision . If you mu st transport
fuel to use for your lawn mower , snow blower , etc. , be very c areful
and always ob serve local and state laws regarding the u se , tran s­
port ation and storage of su ch fuel containers . Make certain the
c ontainer meets industry standard s (ANSI/ASTM F852 · 86 1.
0 Note
Neve r d rive your vehicle until the fuel tank is completely emp ty . The
irregular supp ly of fuel can cause misfiring . Gasoline could enter
t he e xhaus t system and damage the cataly tic converter. •

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 filler 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 filler cap properly and completely. An improperly closed fuel
filler cap may also cause the MIL lamp=>
page 29 to come on.
& 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
refuelling. •
Unlocking the fuel filler flap by hand
You can open the fuel filler flap by hand if the power
locking system should fail .

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 ­

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 360. 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 363.
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 357, "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 a ll 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 ... 2208 ...
means that the tire was produced in the 22th week of 2008 . T he
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 351) and dividing by two. _..
