2017 AUDI Q7 fuel cap

Cockpit overv iew
@ For the sake of the environment
Upshifting early helps you to save fuel and re­
duces operating noise.
@ Tips
Depending on the engine : the engine speed
may be limited when the engine is cold -the
full engine output will not be ava ilable . When
the engine is at operating temperature, the
red area in the tachometer moves to a h igher
RPM range .
Fuel level
The display (j) ~ page 10, fig. 3 or ~ page 10,
fig. 4 only functions when the ign ition is swi tch­
ed on . When the display has reached the reserve
mark, a red LED turns on and the~ indicator
light t urns on~
page 31. The red LED wi ll blink
when the fuel level is very low .
For the tank capacity in you r vehicle , refer to the
Technical Data
~ page 379.
Cl) Note
Never drive until the tank is completely emp­
t y. The irregular supp ly of fuel that results
from that can cause engine misfires . Uncom­
busted fuel will then enter the exhaust sys ­
tem . This can cause overheating and damage
to the cata lytic converter .

On-Board Diagnostic
System (OBD)
Malfunction indicator lamp (MIL)
The malfunction indicator lamp (MIL) ¢'4 in the
instrument cluster is part of the On-Board Diag­
nostic System (OBD II).
The indicator light turns on when the ignition is
switched on and turns off once the engine is
started and is running in idle at a stable speed.
This indicates that the MIL is functioning correct­
ly .
If the light does not turn off after starting the
engine
or turns on while driving, this may indi­
cate there is a malfunction in the engine. If the indicator turns on, the catalytic converter may be
damaged .
Drive
with reduced engine performance (avoid
high speeds for extended periods of time and/or
fast acceleration) and have the malfunction cor­
rected. See an authorized Audi dealer or author ­
ized Audi Service Fac ility .
The electronic speed limiter may be faulty if the
indicator light turns on . For additional informa­
tion, see¢
page 102, Electronic speed limiter .
The MIL indicator light may also turn on if the
fuel filler cap is not closed correctly

On-Board Diagnostics
Fig. 19 Locatio n of Data Li nk Connector (DLC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
s igned a code. In case of a malfunction , the com­
ponent will be identified and the fault stored as a
code in the control module memory.
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel filler cap is prop­
erly closed (only vehicles with gasoline engine)
<=>page 316 .
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (generic scan tool for OBD).
In order to connect the special diagnostic equip­
ment, push the plug into the Data Lin k Connector
(DLC). The DLC is located to the right of the hood
release
¢ fig . 19 .
Your authorized Aud i dealer or qualified work­
shop can interpret the code and perform the nec­
essary repair.
_& WARNING ~ ~ ·
Do not use the diagnostic connector for per-
sonal use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a colli­
sion!

The fuel tank capacity of your vehicle is listed in
the
T ec hnical Dat a section ~ page 3 79.
To avoid fuel spill ing or evaporating from the fuel
tank always close fuel cap p roperly and com­
p letely . An improperly closed fue l filler cap may
a lso cause the MIL lamp~
page 21 to come on.
A WARNING -
Not paying attention when fueling or han ­
dling fue l incorrectly can lead to fires, exp lo ­
sions or serious in juries.
- Fuel ignites easily and can cause serious
burns and other injuries.
- If you do not switch the engine off when fu ­
eling and/or do not insert the fuel nozz le
completely into the tank opening, fue l can
leak out or run over. Leaked fuel can ignite
and start a fire.
- Do not use the telephone whi le fueling. The
electromagnetic rays can cause sparks,
wh ich can ignite fuel vapors and start a fire.
- Do not sit in your vehicle while fueling. If
you must make an except ion and enter your
vehicle again wh ile fue ling, close the door
and touch meta l to discharge static electric­
ity befo re touch ing the fue l nozzle . Static
elect ricity can create spar ks, wh ich can ig ­
ni te vapo rs when fue ling.
- Do not smoke or have an open flame in the
area when fueling your veh icle o r filling a
f uel contai ner because th is increases the
risk of an explos ion .
- For yo ur safety , carrying f uel containers in
yo ur vehicle is no t recommended. Whethe r
f ull or empty, the conta iner can leak a nd
cause a fire in the event of an accident .
- If you must make an exception and trans­
port a fuel container, note the following :
- Never fill the fuel container with fuel
while it is in or on the vehicle. Stat ic elec­
tr icity is d ischa rged when filling wh ich can
cause the f uel vapors to ignite and in­
creases the r isk of an explos ion.
- Always p lace a fuel containe r on the
g ro u nd before fi llin g.
Ch eck ing and Filling
-Always hold the fue l nozzle completely in
the fuel container when filling.
- If the fuel container is made of metal, the
fuel nozzle must always be in contact with
the container when filling it with fuel. This
prevents stat ic electricity from discharg­
ing .
- Never spill fuel in the vehicle or the lug­
gage compartment. Evaporated fuel is ex­
plosive and increases the risk of serious in­
jury or death .
- Follow lega l requirements when using,
stor ing and transporti ng fuel conta iners .
- Make sure the fuel container conforms to
industry standards (ANSI/AS TM F8S2-86).
@ Note
- Remove spilled fuel from vehicle pa int im­
mediately, because it can damage paint.
- Never drive unti l the fuel tank is complete ly
empty. The irregular supply of fue l that re­
sults from that can cause eng ine misfires.
Uncombusted fuel will enter the exhaust
system and increase the risk of damage to
the catalytic converte r.
- If the fue l tank runs complete ly empty in a
vehicle with a
diesel eng ine , the ignition
must remain swit ched on fo r at least 30
se conds afte r ref ueli ng before starti ng the
eng ine. It may take longer than usual fo r
t he engine to s tart, even up to a minu te.
T his is because the air must first b leed out
of the fue l system when starting the eng ine.
@ For the sake of the environment
Do not overfill the fuel tank, otherwise fuel
can leak out when the veh icle is warming up.
(D Tips
D iesel ve hicles are eq uipped w ith a diesel mis­
fueling guard .
It allows the vehi cle to be fu­
eled on ly with a diesel fuel pump nozzle. A
worn or damaged nozzle or a nozzle that is
too small may not be able to open the diese l
misfueling guard. If this is the case, try turn­
i ng the nozzle before inserting it in the fue l
filler neck, use a different fuel pump, o r see
