2011 AUDI Q7 ignition

Intelligent technology
'-------------------------------------------------
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the remote key or power seat adjust­
me nt, may not be available. The convenience functions will be avail­
able again when you turn on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for example, with the engine turned off or
use other MMI functions, the battery is being discharged.
If start ing capability is jeopardized due to energy consumption, the
following warning appears in the MMI display:
Please start engine, otherwise system will switch off in
3 minutes .
The warning indicates that the system will be turned off automati­
cally after 3 minutes. If you wish to continue using the functions, you
have to start the engine.
With the engine running
Although electrical energy is generated when the vehicle is being
driven, the battery can become discharged. This happens mostly
when little energy is being generated and a great deal consumed and
the battery's state of charge is not optimal.
To bring the energy balance back into equilibr ium, consumers which
require especially large amounts of energy are temporarily cut back
or switched off. Heat ing systems in particular require a great deal of
energy. If you notice, for example, that the heated seats* or the
heated rear window are not heating, they have been temporarily cut
back or switched off. These systems will be available again as soon as
the energy balance has been restored .
You will also notice that engine idle speed has been increased
slightly. This is norma l and not a cause for concern. By increasing
engine idle speed the additional energy required is generated and the
battery is charged.
Driver notification in the instrument
cluster display
If battery power drops into the range where it can limit the ability of
the engine to start, this is shown in the instrument cluster display
with the following driver message:
i...-3 Low battery charge: battery will be charged while driving
This notification reminds you that the starting capability of the
engine may be limited. As soon as you start driving again, the battery
w ill be recharged and the notification will go out.
Driver notification appears and goes out again
If th is driver notification appears after the ignition is turned on or
whi le driving and it goes out again after a while, the battery has been
adequately recharged.
Driver notification appears and does not go out
again
If this driver notification appears after the ignition is turned on o r
wh ile driving and does not go out again, the battery's state of charge
is not in the optimal range. Starting ability is restricted. Have the
battery checked as soon as possible by an authorized Audi dealer or
qualified workshop. •

Engine compartment
Be especially careful when cleaning the engine compa rt­
men t.
Always switch off the ignition before cleaning the engine=:>& .
Plenum panel
Remove leaves from the plenum panel in front of the win dshi eld
unde r th e eng ine hood . T hi s prevents the water d rain holes from
becoming b locked, and it prevents debris from entering the vehicle
inter io r th rough the heat ing and vent ilation ducts .
Corrosion protection
The eng ine compartment and transmission have been cor rosion­
protected at the factory.
Good ant i-cor rosion treatment is very impo rtant , pa rtic ular ly in the
w inter . If the vehicle is frequently driven on sa lt treated roads, the
en tire eng ine compar tment and plenum p anel sho uld be thoroug hly
cleaned at the end of winter and retreated to prevent salt damage. At
t he same t ime, the underside of the vehi cle should be washed as well.
If the e ng ine compartment is clea ned at any t ime with grease
removing so lutions
2l , or i f you have the engine washed , the anti ­
co rros io n treatment is a lmost a lways removed as w ell.
It is t herefore
essential to have a long-last ing corrosion p rotect ion reapplied to all
surfa ces, seams, jo ints and compo nents in the engi ne co mpa rt ment .
& WARNING
Be aware: The engine compartment of any motor vehicle is a
potentially hazardous area .

Fuel supply
Applies to vehicles : w ith gasoline eng in e
Gasoline
Using the right fuel helps keep the environment clean and
prevents engine damage.
Fuel recommendation
The fuel recommended for you r vehicle is unleaded premium grade
gasoline . See also~
page 365, "Data". Audi recommends using TOP
TIE R Detergent Gasoline with a minimum octane rating of 91 AKI (95
RON) . For more information on TOP TIER Detergent Gasoline, please
go to the official website (www.toptiergas .com).
Th e recommended gasoline octane rating for your engine can also be
found on a labe l located on the inside of the fue l filler flap. This rating
may be specified as AK I o r RON.
Your vehicle may also be operated using unleaded regular gasoline
with a minim um octane rating of 87 AKl/91 RON . However, using 87
AKl/91 RON octane fuel will slightly reduce engine performance .
Use unleaded gasoline only. Unleaded gasoline is available
throughout the USA, Canada, and in most European countries. We
recommend that you do not take your vehicle to areas or countries
where unleaded gasoline may not be availab le.
For more information on refueling your vehicle, see~
page 293.
Octane rating
Octane rating indicates a gasoline's ability to resist engine damag ing
" kno ck" caused by prematu re ignition and detonation. Therefore,
buying the correct grade of gasoline is very important to help prevent
possible engine damage and a loss of engine performance.
Safety first
Gaso line most commonly used in the United States and Canada has
the following octane ratings that can usually be found on the filler
pump:
• Premium Grade: 91 - 96 AKI
• Regular Grade: 87 - 90 AKI
E xplanation of the abb reviations :
AKI= Anti Knock Index= (R +M)/2 = (RON+MON)/2
RON= Research Octane Number
MON= Moto r Octane Number.
0 Note
• Do not use any fuel with octane ratings lower than 87 AKI or 91
RON otherwise expens ive engine damage will occur.
• Do
not use leaded gasoline . T he use of leaded gasoline w ill
seve rely damage your veh icle's cata lytic converter and its ability to
control exhaust emiss io ns. •
Ap plies t o vehicl es: w ith gasoline eng in e
Blended gasoline
Use of gasoline containing alcohol or MTBE (methyl
tert iary butyl ether)
You may use unleaded gasoline blended w ith alcohol or MTBE
(common ly referred to as oxygenates) if the blended mixture meets
the following criteria:
Blend of gasoline methanol (wood alcohol or methyl alcohol)
• Anti-knock index must be 87 AKI o r higher.
• Blend must contain no more than 3% methanol.
• Blend must contain more than 2% co-solvents .
Vehicle care Technical data

Fuel supply and filling your fuel tank
Your vehicle fuel tank has an on-board refuelling vapor recovery
system . This feature helps to prevent fuel vapors from escaping from
the tank and polluting the environment while you refuel your vehicle.
In order to fill the tank properly while protecting the environment,
please follow this refueling procedure carefully.
& WARNING
Under normal operating conditions, never carry additional fuel
containers in your car. Gas canisters and other containers used to
transport fuel can be dangerous. Such containers, full or empty, may leak and could cause a fire in a collision. If you must transport
fuel to use for your lawn mower, snow blower, etc., be very careful and always observe local and state laws regarding the use, trans­
portation and storage of such fuel containers. Make certain the
container meets industry standards (ANSI/ASTM F852 -86).
0 Note
Never drive your vehicle until the fuel tank is completely empty. The
ir regular supply of fuel can cause misfiring. Gasoline could enter the
exhaust system and damage the catalytic converter. •

locking, the fuel filler flap is automatically unlocked or
locked. Refuel the vehicle with the ignition turned
off.
Taking the fuel cap off
- To open the fuel filler flap, press on the left side of the
flap ~ fig. 224 -arrow-.
- Unscrew fuel filler cap counter-clockwise and hang it on
the fuel filler flap~ fig. 225.
- Check the label on the inside of the fuel filler flap to deter­
mine if the vehicle must be fueled with gasoline or diesel
fuel.
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.

Fuel supply and filling your fuel tank
(I) Tips
• Runn ing your eng ine 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 ind icate the correct fuel level after refuel­
ling.
• Diesel vehicles* are equipped w ith a mechanism to prevent incor­
rect fueling. They can only be fueled with diesel pump nozzles. A
worn, damaged, or improperly specified nozz le may not allow this
mechanism to open, thereby preventing refueling. If you cannot
insert the pump nozzle, rotate it in the tank opening. This should
open the mechanism and allow refueling. •
Unlocking the fuel filler flap by hand
You can open the fuel filler flap by hand if the power
locking system should fail.

TDI clean diesel
App lies to veh icles: w ith diese l eng ine
General information
On TOI clean diesel vehicles, an urea solution (AdBlue®) is injected
into the exhaust system before a specia l catalytic converter to reduce
nitrogen emissions.
The Ad Blue is stored in a separate tank in the vehicle and f illed during
maintenance intervals. Under norma l driving conditions, there will be
enough Ad Blue to last from one maintenance interval to the next.
Because of this, the scheduled maintenance intervals should always
be followed.
The Ad Blue usage accounts for approximately 0.5% to 1 % of the
diesel fuel that is us ed. The Ad Blue tank capacity is approximately 6
gallons (23 liters). ..,_
