fuel additives AUDI S3 2015 Owners Manual

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.
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
specified criteria in this chapter .
- If you are unable to determine whether
or not a particular fuel blend meets the
specificat ions, ask your service station or
i ts fuel supp lier.
- 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
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
M
N fuel systems clean, they are not equally effec-o
iii 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.
CJ) Note
Damage or malfunction due to poor fuel
quality is not covered by the Audi New Ve­
hicle Limited Warranty.
Diesel fuel
App lies to vehicles : wit h diese l eng ine
Always use ULSD (Ultra Low Sulfur Diesel)
No. 2 . The ULSD No. 2 meets the ASTM D975.
Diesel fuel with concentrations of biodiesel
higher than 5
% such as B11, B2O or B1OO 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.
ULSD No. 2 may not be available outside the
USA and Canada. Be sure to check before trav­
eling to other countries.
ULSD No. 2 can become thicker in very cold
temperatures, and this can impair the en­
gine's starting and running. Depending on the
season, gas stations provide ULSD No . 2 that
flows better in cold temperatures so that you
can continue operating your vehicle as usual.
(D Note
- Your vehicle's diesel engine was de­
signed solely for use with ULSD No. 2.
Therefore, never use gasoline, heating
oil, other fuels or flow improvers. These
contain substances that will severely
damage the fuel system and the engine.
Such damage will not be covered by your
New Vehicle Limited Warranty.

~ If there was no Ad Blue left in the tank and a
range of
O mi (0 km) was displayed in the
instrument cluster, switch the ignition on
for about 15 seconds before starting the en­ gine.
_& WARNING
Ad Blue can irritate the skin, eyes and res­piratory system. If there is contact with
the fluid, flush immediately with plenty of
water. Consult a physician if necessary.
(D Note
- Only use Ad Blue that conforms to the standard ISO 22241-1. Do not mix any
additives with the Ad Blue and do not di­lute it with water .
- Do not add Ad Blue to the diesel tank or
add diesel fuel to the Ad Blue tank. Mix­
ing can lead to damage to the engine
and the Ad Blue tank system. Warranty
does not cover damage caused by this.
- AdBlue attacks surfaces such as painted
vehicle components, plastic and carpet.
Remove the fluid as quickly as possible
with a damp cloth and plenty of cold wa­
ter. If the Ad Blue has already crystal­ lized, use warm water and a sponge .
AdBlue residue that is not removed will
crystallize and can damage the affected
surface .
- Do not store the refill bottle in the vehi­ cle. If it leaks, the escaping Ad Blue could
damage the vehicle interior.
- Do not allow AdBlue to come into con­
tact with clothing . If there is contact
with the fluid, flush immediately with
plenty of water.
@ Tips
- You can obtain refill bottles from an au­
thorized Audi dealer or authorized Audi
Service Facility.
- Follow the AdBlue manufacturer's in­
structions for use and storage.
Checking and Filling 217
Hood
Working in the engine compartment
Special care is required if you are working in
the engine compartment
For work in the engine compartment such as
checking and filling fluids, there is a risk of
injury, scalding, accidents, and burns. For
this reason, follow all the following listed
warnings and general safety precautions.
The engine compartment is a dangerous
area.
c::> .&. .
_8 WARNING
To reduce the risk of injuries, complete the
following steps before opening the hood:
- Turn the engine off.
- Switch the ignition off.
- Set the parking brake.
- Place the selector lever in the P position.
- Let the engine cool down.
- Never open the hood when you see that
steam or coolant drips from the engine
compartment- there is a danger of burns! Wait until no steam or coolant
flows out .
- Keep children away from the engine com­
partment.
- Never spill fluids on a hot engine . These
fluids (such as the freeze protection con­
tained in the coolant) can catch fire .
- Avoid short circuits in the electrical sys­
tem, especially the battery .
- When working in the engine compart­
ment, remember that the radiator fan
can switch on even if the ignition is
switched off, which increases the risk of
personal injury.
- Never open the cap on the coolant ex­
pansion tank when the engine is warm.
The cooling system is under pressure.
- To protect your face, hands, and arms
from hot steam or coolant, cover the cap
with a large cloth when opening.
