2010 AUDI A5 COUPE fuel

The amount of oil used is related to engine load and speed .
It is normal for the oil consumption of a new engine to reach its
lowest va lue after a certain mileage has been driven.
You must drive your vehicle about 3,000 mi les (5,000 kilometers)
before you can properly assess oil consumption.
This also applies to fuel consumption and engine output.
0 Note
• Have your vehicle maintained properly and in accordance with
the service recommendations in your Warranty

booklet. Lack of proper maintenance as well as improper use of the
vehic le wi ll impair the function of the emission control system and
cou ld lead to damage.
• Do not alter or remove any component of the Emiss ion Contro l
System unless approved by the manufacturer.
• Do not alter or remove any device, such as hea t shields,
switches, ignition wires, valves, which are designed to protect your
vehicle's Emission Control System and other important vehicle
components. •
Fewer short trips
~-----------------
Fu e I consumptio n will always be relat ively high on short
tri ps.
- Try to avo id driving s hor t distan ces wit h a cold engine.
The engine and catalytic converter have to reach their optimal oper­
ating t emper ature
to reduce fuel consumption and noxious emis­
sions effective ly .
Just after starting, a cold engine in a mid-size car only achieves a
fue l economy of 6 -8 miles per gallon (30 -40 1/100 km). After about a
half a mile, fuel economy climbs to 12 mpg (201/100 kml. After about
2.5 miles (4 km), the engine is at its proper operating temperature

and fuel economy has reached a normal level. So you can see that
you sh ould avoid short trips whenever possib le .
The

Trailer load d is trib ut ion
Be sure the load in the trailer is held securely in place to prevent it
from shifting forward, backward or sideways.

tions" on
page 249.
En gin e c ool ing syst em
Towing a trailer makes the engine work harder. It is important that
the cooling system 's performance is up to the additiona l load. Make
sure that the cooling system has enough flu id.
Ti re press ure
When towing a trailer, inflate the tires of your vehicle to the cold tire
pressure listed under "Full load" on the labe l located either on the
driver's side B-pillar (visible when the door is open} or inside the fuel
filler flap . Inflate trailer tires to trai ler and tire manufacturers' spec ­
ifications.
Ligh ts
The headlight settings should be checked with the trailer attached
before driving off . Check to make sure both vehicle and trailer lights
are working properly .
Safe ty c hain s
Be sure trailer safety chains are properly connected from the trailer
to the hitch on the vehicle. Leave enough slack in the chains to
permit turning corners. When you install safety chains, make sure
they will not drag on the road when you are driving.
The chains should cross under the trailer tongue to prevent it from dropping in case of separation from the hitch.

Driving instructions
Driving with a trailer always requires extra care and
consideration.
To obtain the best possible handling of veh icle and trailer,
please note t he following :
Do not tow a loaded trailer when your car itself is not
loaded .
- Be especia lly careful when passing other vehicles .
Observe speed l imits .
Do not drive at the maximum permissible speed.
Always apply brakes early.
Monitor the temperature gauge.
W eight distrib utio n
Towing a loaded trailer with an empty car results in a h ighly
unstable distribution of weight . If this cannot be avoided, drive at
very low speeds only to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control. This means that
t he tow vehicle should be loaded to the extent possible and permis ­
sible, while keeping the trailer as light as possib le under the circum ­
stances . Whenever possible, transfer some cargo to the luggage
compartment of the tow vehicle whi le observing tongue load
requirements and vehicle loading considerations.
S pee d
The higher the speed, the more difficu lt it becomes for the d river to
control the rig. Do not drive at the maximum permissible speed.
Reduce your speed even more if load, weather or wind conditions
are unfavorable -particularly when going downhill .
Reduce vehicle speed
i mmed iatel y if the trailer shows the slightest
sign of swaying .
Do not try to st op the swa ying b y accelerating.

Care of exterior
Washing
F requent washing protects the vehicle.
The best protection against environmental influences is frequent
washing a nd waxing. How often this is required depends on :
• How much the vehicle is used
• Where the vehic le is pa rked (garage, in the open under trees,
etc.I
• The seasonal and weather cond itions
• Environmental influences
The longer bird dropp ings, insects, tree resin, road and industrial
grime, tar, soot, road salt and other materials remain on the vehicle
b ody, the more lasting their destructive effects will be. High temper ­
atures caused by exposure to intense sunlight intensify the corro -
sive effect, particularly when humidity is high as wel l. .,

Fuel supply and filling your fuel tank
Gasoline
Fuel supply Using the right fuel helps keep the environment clean and
prevents engine damage.
Fuel r ecomm end ati on
The fuel recommended for your vehic le is unl eade d prem ium grade
gaso line . See also ~
page 337, "Data". Audi recommends using TOP
T IER Detergent Gasoline with a minimum octane rating of 91 AKI (95
RON). For more information on TOP TIER Detergent Gaso line, please
go to the official website (www.toptiergas .com).
The recommended gasoline octane rating for your engine can also be found on a label located on the inside of the fuel fille r flap. This
rating may be specified as AK I or RON .
Your vehic le may also be operated us ing unleaded regular gasoline
with a minimum octane rating of 87 AKl/91 RON . However, using 87
AKl/9 1 RON octane fuel will slightly reduce engine performance.
Use unle ad ed ga so line only . Unleaded gaso line is avai lable
throughout the USA, Canada, and in most European countries. We
recommend that you do not take your vehicle to areas or countr ies
where un leaded gasoline may not be available .
For more information on refueling your vehicle, see~
page 266 .
Octane ra tin g
Octane rating indicates a gaso line's ability to resist engine
damaging "knock" caused by premature ignition and detonation.
Therefore, buying the correct grade of gaso line is very important to
help prevent possible engine damage and a loss of engine perfor ­
mance.
F ue l supply and fillin g you r fu el tank
Gasoline most common ly used in the United States and Canada has
the following octane ratings that can usua lly be found on the filler
pump:
• Premium Grade : 91 -96 AKI
• Regular Grade: 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti Knock Index= (R +M)/2 = (RON +MON)/2
RON = Research Octane Number
MON
= M otor Octane Number .
0 Note
• Do not use any fue l with octane ratings lower than 87 AKI or 91
RON otherwise expensive engine damage will occur .
• Do
not use leaded gasoline. The use of leaded gasoline w ill
severe ly damage your vehicle's catalytic converter and its abi lity to
control exhaust emissions. •
Blended gasoline
Use of g aso line containing alco hol or M TB E ( meth yl
t er tiary butyl e ther )
You may use unleaded gasoline blended with alcohol or MTBE
(commonly referred to as oxygenates) if the blended mixture meets
the follow ing criteria:
Bl end of g asoline m eth anol (wood al coho l or methyl alc oh ol)
• Anti-knock index must be 87 AKI or higher .
• Blend must contain no more than 3% methanol.
• Blend must contain more than 2% co-solvents.
Vehicle care I t •

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, built-up carbon
deposits can rob your engine of peak performance.

- 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 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 cap properly and completely.
& 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.
