2009 AUDI Q7 refuelling

On-Board Diagnostic system (08D)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIU ~ in the instrument cluster
~ page 17, fig. 7 is part of the On-Board Diagnostic (OBD ID system.
The warning/indicator light illuminates when the ignition is
switched on and goes out after the engine starts and the idle has
stabi lized . This indicates that the MIL is working properly.
If the light does not go out after the engine is started, or illuminates
while you are driving, a malfunction may exist in the engine system.
If the light starts flashing, the catalytic converter could be damaged.
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerations) and have the condition
corrected. Contact your authorized Audi dealer.
If the light illuminates, the electronic speed limiter may also be
malfunctioning . For more information~
page 29, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate
~ page 327. •
On-Board Diagnostics
Con tro ls and eq uip­
ment
Fig . 16 Location of
Data Link Connector
(D LC )
Driver information display
On-Board Diagnostics monitors the components of your emission
control system. Each monitored component in your engine sys tem
has been assigned a code. In case of a malfunction, the component
wil l be identified and the fault stored as a code in the control
module memory .
The M IL light may also illuminate if there is a leak in the on -board
fuel vapor recovery system. If the light illuminates after a refuelling,
stop the vehicle and make sure the fuel filler cap is properly closed
~ page 327.
In order to make an accurate diagnosis, the stored data can only be
d isplayed using special diagnostic equipment (generic scan tool for
08D).
In order to connect the special diagnostic equipment, push the plug
into the Data Link Connector (DLC). The DLC is located to the right of
the hood release~ fig. 16.
Your authorized Audi dealer or qualified workshop can interpret the
code and perform the necessary repair. •
Electronic speed limiter
Your vehicle may be factory equipped with tires that are rated for a
maximum speed of 130 mph (210 km/h). This is less than the
maximum speed of your vehicle. To reduce the risk of sudden tire
failure and loss of control if the vehicle is operated at excessive
speeds, your vehicle also has an electronic speed limiter. The elec­
tronic speed limiter prevents your vehicle from going faster than the
tire speed rating. For more information~
page 359.
If the engine control unit receives faulty vehicle roadspeed signa ls,
the Malfunction Indicator Lamp (MIU will i lluminate . If this
occurs, contact the nearest authorized Audi dealer for assistance. .,.

The labe l on the inside of the fuel filler flap tel ls you the correct fuel
fo r your vehicle . For mo re information about fuel specifications, see
=> page 325.
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 .
