234 Driving and en vironm ent
,8. WARNING
-Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the diesel par
t icu late filter could start a fire .
- Do not apply an underbody protectant in the exhaust system area or a fire could start.
Avoid damaging the vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam
aged.
This is especia lly true for vehicles with low
slung chassis (sports chassis)* and fully load
ed vehicles.
Shutting down vehicle
If you would like your vehicle to remain inop
erative for a longer period of time, contact an
Audi or other specialized dealer . They can ad
vise you on necessary precautions e.g . corro
sion prevention, maintenance and storage. Pay attention to additional information con
cerning the battery. Refer to
c::> page 268.
Operate your vehicle
economically and minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving style
- operating conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your
fuel consumption by 10-15 percent . This sec
tion will give you some tips on how you can help the environment and your pocketbook.
(D Tips
The consumption estimates as published by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre
spond to your actual consumption on the road, which will vary depending upon vehi
cle load and speed, road and weather con
dit ions, trip length, etc.
· Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they ore ac
celerating.
., Avo id unnecessary accelerating and brak ing.
Vehicles use the most fuel when they are ac
celerating . If you anticipate what is going to
happen next, you will need to brake less and,
thus, acce lerate less. Let the vehicle coast
whenever possible -for examp le 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 consump
tion, engine wear, and does not disturb the environment.
Fuel consumption, exhaust emissions and en
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
than the posted speed limit and weather con
ditions permit.
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
11-Shut the engine off when you are not driving
the vehicle.
11-Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traffic
jams, when waiting for trains to pass at rail
road cross ings, or at traffic lights that have
long waits on red. Turning the engine
off for
just 30-40 seconds saves more fuel than is
burned starting the engine again.
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
(D Note
Do not leave engine idling unattended af
ter starting. If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over
heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel .
11-Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
authorized Audi dealer helps to ensure that it
runs properly and economically. The condition
of your vehicle not only affects its safe ty and
ab ility to hold its value, it also affects fuel
consumption .
Check your oil each time you fill your tank.
Driving and environment 235
The amount of oil used is re lated to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven.
You must drive your vehicle about 3,000 miles
(S,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en
gine output.
(D Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec
ommendations in your Warranty
& Main
t enance booklet. Lack of prop er mainte
nance as well as improper use of the ve
hicle will impair the function of the
emission cont ro l system and could lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
11-Try to avoid driv ing short distances w ith a
cold engine.
T he engine and cata lytic converter have to
reach their optimal operating temperature to
reduce fuel consumpt ion and noxious emis
s ions effectively .
Just after starting, a co ld engine in a mid-size
car on ly achieves a fuel economy of 6-8 mi les
per gallon (30-40 l/l00km). After about a
half a mile, fuel economy climbs to 12 mpg
(20 l/100 km). After about
2 .5 miles (4 km), liJI,

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 sea
sonal adjustment is more likely to be made in
time.
(CT) Note
- Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo
nents 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 responsibility 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 prob lems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
Applies to vehicles: with gasoline engine
A major concern among many auto manufac
turers 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 effec
tive.
Audi recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your
engine of peak performance.
(D Note
Damage or malfunction due to poor fuel
quality is not covered by the Audi New Ve
hicle Limited Warranty.
Diesel fuel
Applies to vehicles: with diesel engine
Always use ULSD (Ultra Low Sulfur Diesel) sul
fur content 15 ppm or less.
The ULSD (Ultra Low Sulfur Diesel) meets the
ASTM-D-975 (grade 2).
Diesel fuel with a higher concentration than
ULSD-Diesel No. 2 ASTM D975 and Bio-die
sel with a higher concentration than 5
% like
811, 820 or 8100 are strictly prohibited.
Service station fuel pumps are labeled with
the correct fuel information for easy recogni
tion by the user. If the diesel fuel pump is not
labeled ask the station operator what fuel is
being dispensed before filling up your vehicle.
Service stations offering Diesel fuel are gener
ally located on truck routes or major high
ways. Directories of Diesel fuel stations are usually available at Diesel fuel stations.
Some states in the USA require permits to
purchase Diesel fuel. Check with your State
Motor Vehicle Department.
Diesel fuel may not be available outside the
USA and Canada. Be sure to check before trav-
eling to other countries.

Winter operation
At temperatures below 20° F (-7° C), Diesel
fuel No.
2 loses its fluidity due to wax separa
tion, which may clog the fuel filter or tank fil
ter and keep the engine from running .
To help the filter from being clogged by wax,
the fuel filter in your vehicle is automatically
preheated. Preheating the fuel filter makes
operation of your vehicle possible with Diesel
fuel No . 2 down to -10° F (-24° C).
If you expect temperatures below 5° F
(-15° C) ask your fuel dealer whether their
Diese l fuel No. 2 is sufficiently winterized for
the prevailing and expected temperatures.
If not winterized or insufficiently winterized
Diesel fuel has already thickened to the extent
that the engine will not start, warm the vehi
cle up by leaving it in a heated garage.
It is normal that the engine noise leve l (die
seling) is louder during the warm-up period in
winter.
It is also norma l when whitish-blue
smoke comes out of the tailpipe after start ing
and during warm-up . The amount of smoke
depends on the outs ide temperature.
Do not let your Diese l engine id le unnecessari
ly after a cold start. Driving off slowly will
shorten the warm-up period .
A WARNING
-Never use "starting assist fluids." They
may be potent ially explosive or cause a
"run-away" engine condition. This could
result in serious engine damage and per
sonal injury.
- Never use fuel line anti-freeze offered for
gasoline engines .
0 Note
- Refueling with gasoline when your vehi
cle has a diesel engine can cause very se
rious and expens ive engine and fuel sys
tem damage that is not covered by any
A udi Limited Warranty.
- If you put any amou nt of incorrect fuel in
the fuel tank, do not start the engine un-
