180 Driving and en vironm ent
8_ WARNING
After driving through water, mud, slush,
etc ., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
store the full braking effect.
(D Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv­
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switc h the engine off when driving
t hr ough water.
- Keep in mind that oncoming vehicles
may c reate waves that raise the water
l evel and make it too deep fo r you r vehi­
cle to dr ive through safely.
- Avoid dr iving thro ugh salt water because
i t can ca use corrosion.
Warming up and
cooling down
-
By carefully warming up and cooling down
your ve hicle, you can he lp ensure that it is not
overstressed unnecessarily dur ing sporty driv ­
ing.
When warming up, the vehicle is d riven at a
maximum engine speed of 6000 RPM in order
to raise the engine oi l temperature to a mini ­
mum of 140
°F (60 °(). The tires also only
reach their full road holding capability once
they have warmed up .
The cooling fan can contin ue to run in your ve­
h icle after the engine is switched off. Howev­
er, driving the vehicle to cool it down is part ic­
ularly important. During sporty driving, the
engine and brakes, the ex ha ust system, and
the transm ission all become extremely hot.
B efore you park the vehicle, you shou ld drive it for a few miles/kilometers at
light load in
the low rpm range to allow it to cool down.
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
.. Always use lead-free gasoline c:> page 190,
Fuel supply.
.. Never run the tank down all the way to emp­
ty .
.. Never put too much moto r oil in your engine
c:> page 199, 't::71 Adding engine oil .
.. Never try to p ush- or tow -sta rt yo ur vehicle.
The catalytic converter is an efficient "clean­
up" device bu ilt into the exhaust system of
t h e vehi cle. The cata lytic conve rter bu rns
many of the pollu tan ts i n t he exh aust gas be­
f ore they are re lease d into the atmosphere.
T he exclusive use of unleaded fue l is critica lly
impor tant for the life of the catalyt ic convert­
er and prope r fu nct ion ing of the engi ne.
8_ WARNING
- T he temperature of the exhaus t system
is high, both when driving and after stop ­
p ing the engine.
- Never touch the exhaus t tail pipes once
they have become hot . This cou ld result
in burns .
- Do not park or operate the vehicle i n
areas where the hot exha ust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additional undercoating or
rustproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
ver ter or heat shields . Dur ing driv ing, the
substance used for undercoating could
overheat and cause a fire.

Many gasoline grades are blended to perform
especia lly we ll 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.
Q;) 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
spec ified criter ia in this chapter .
- If you are unable to determine whether
or not a particular fuel blend meets the
spec ificat ions, ask your service station or
i ts 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 respons ibility of Audi and are not
covered under the New Vehicle or the
Emission Control System Warranties.
- If you experience a loss of fue l economy
or driveability and performance prob­ l ems 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 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 cer tain
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.
Fuel supply and filling your fuel tank 191
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, built -up carbon deposits can rob your
engine of peak performance.
CJ) Note
Damage or malfunction due to poor fuel
quality is not covered by the Audi New Ve­
hicle Limited Warranty.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
s ide panel behind the fuel filler flap.
If the power locking system should fail, you
can still open the flap manually -for detailed
instructions see
~ page 193.
You can find the fuel tank capacity of your ve ­
hicle in
~page 262 .
The label on the inside of the fuel filler flap
tells you the correct fuel for your vehicle. For
more information about fuel specifications,
see
~ page 190 .
Your vehicle fuel tank has an on-board refuel­
ling vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and pollut ing the environment while you
refuel your vehicle. In order to fill the tank
properly while protecting the environment,
please follow this refueling procedure careful­
ly.
A 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 con­
tainers, full or empty, may leak and could
cause a fire in a collision . If you must
transport fuel to use for your lawn mower, ..,.
