2010 AUDI Q7 fuel

Driving and environment
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are accelerating.
- Avo id unnecessary acce lerating and braking .
Vehicles use the most fuel when they are accelerati ng. If you antici­
pate what is going to happen next, you will need to brake less and,
thus , accelerate less. Let the vehicle coast whenever possible - for
example when you see that the next traffic light is red. •
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
- Try and keep well below your car's maximum speed.
Accelerating gently reduces fuel consumption, engine wear, and does
not disturb the environment.
Fuel consumption , exhaust emiss ions and eng ine no ise increase
disproportionately at high speeds. If you drive at approximately three
quarters of top speed, fuel consumption w ill be reduced by one ha lf.
Never drive faster than the posted speed limit and weather condi­
tions pe rm it. •
Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
- Shut the eng ine off when you are not driving the vehicle.
- Do not warm up the vehicle by letting the eng ine run at
idle .
It makes sense to shu t off t he eng ine in traffic jams, when wa it ing for
tra ins to pass at railroad crossings, or at traffic lights that have long waits on red
. Turning the eng ine off for just 30-40 seconds saves
more f uel than is burned start ing the engine aga in.
It takes a long t ime for the engine to warm up fully when it is ru nning
at idle . However, wear and noxious emissions are especia lly high
when the eng ine is wa rming up. So you shou ld drive away as soon as
you start the engine and avoid running at high rpms while the engine
is still warming up .
0 Note
Do not leave engine idling unattended afte r start ing. If warning
lights should come on to indicate improper operation, they would go
unheeded. Extended idling also produces heat, which cou ld result in
overhea ting or other damage to the vehicle or other property. •
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
- Have your vehicle serviced at regular intervals.
By having your vehicle regularly serv iced by an authorized Aud i dealer
helps to ensure that it runs properly and economically. The condition
of your vehicle not only affects its safe ty and ability to hold its value,
it a lso affects fuel con sumption .
Che ck your o il e ach time you fill your t ank.
T he amo unt of oil used is related to engine load and speed.
It is normal for the o il consumption of a new engine to reach its
lowest val ue afte r a certa in m ileage has been d riven.
You must drive your veh icle about 3,000 m iles (5,000 kilometers)
before you can properly assess oi l consumption .
T his also app lies to f uel consumption and engine ou tput. ._

• Do not a lter or remove any device, such as heat shie lds, switches,
ign ition w ires , va lves, which are desig ned to protec t your ve hicle's
Emission Contro l System and other important veh icle components .•
Fewer short trips
F uel consumptio n will always be relatively high on short
trips .
-Try to avoi d drivi ng s ho rt dis tances wit h a cold engine .
The engine and catalytic converter have to reach their optima l oper­
ating temperature
t o reduce f uel consum ptio n a nd noxio us em is ­
sions effectively.
Just after starting, a cold engine in a mid -s ize car on ly achieves a fuel
economy of 6-8 m iles per gallon (30- 40 l/l00km) . After about a ha lf
a mile, fuel economy climbs to 12 mpg (20 l/100 km). After abo ut
2 .5 m iles ( 4 km), t he engine i s at its p rop er operat ing temper ature
and fue l economy has reached a normal level. So yo u can see that you
sho uld avoi d short t rips whenever possible.
T he
out side temperature is a lso c ritical in this regard. Your car
cons umes mo re fue l in the winter than in the summer. •

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 363, "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 289.
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. •

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
Blend of g asoline and ethanol (grain alcohol or ethyl alcohol )
• Anti-knock index must be 8 7 AKI o r higher .
• Blend must not conta in more than 10% ethanol.
Blend of gasoline and M TBE
• Anti-knoc k index must be 87 AKI o r highe r.
• Blend must conta in not more than 15% MTB E.
Sea sonally adjusted ga soline
Many gasoline grades are b lended to perform especially well for
w inte r or summer d riving. Duri ng seasonal change-ove r, we s uggest
that you fill up at busy gas stat ions where the seasonal adjus tment is
mor e likely to be made in time.

If you expect temperat ures below 5° F (-1S° C) ask yo ur fuel dealer
whether their Diesel fuel No . 2 is suffic iently w interized for the
prevailing and expected temperat ures.
If not winterized or insuff ic ie ntly w inte riz ed Diese l fuel has already
thickened to the extent that the engine w ill not start, warm the
vehicle up by leaving i t in a heated garage.
It is normal that the eng ine noise level (dieseling) is louder during the
warm-up period in winte r. It is also normal when whitish -blue smoke
comes out of t he tailpipe afte r start ing and du ring warm-up. The
amount of smoke depends on the outside temperature .

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 f ill 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 fue l can cause misfiring. Gasoline could enter the
exhaust system and damage the catalytic converter. •
