Gasoline additives
Applies to: vehicles with gasoline engine
A majo r concern among many auto manufactur ­
ers is carbon deposit build-up caused by the type
of gasoline you use.
A lthough gasoline grades d iffer from one manu­
facturer to another, they have cer tain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves . A l­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website (www .toptiergas .com) .
Check ing and F illing
A fter an extended period of using inadequate
fuels, carbon deposit bui ld-ups can rob your en ­
gine of peak performance.
@ Note
Damage or ma lf u nction due to poor fue l qual ­
ity is not covered by the A udi New Vehicle
L imited Warranty .

A WARNING
Not pay ing attention when fueling or han ­
dling fuel incorrectly can lead to fires, explo­
sions or serious injur ies.
- Fue l ignites easily and can cause serious
burns and other injur ies.
-
- If you do not switch the engine off when fu­
eling and/or do not insert the fuel nozzle
completely into the tank open ing, fuel can
leak out or run over. Leaked fuel can ignite
and start a fire .
- Do not use the telephone while fueling . The
electromagnetic rays can cause sparks,
which can ignite fuel vapors and start a fire .
- Do not sit in your vehicle wh ile fueling. If
you must make an exception and enter your
veh icle again while fueling, close the door
a nd touch metal to d ischa rge stat ic elect ric­
ity before to uching the f uel no zz le. Static
e lec tricity ca n create spa rks, which ca n ig ­
n ite vapors when fueling.
- Do not smoke or have an open flame in the
a rea whe n fue lin g you r veh icle or filling a
fue l container because this increases the
risk of an explosion.
- F or your safety, carrying fuel containe rs in
your veh icle is not recommended . Whet her
fu ll or empty, the container can leak and
cause a fire in the event of an accident.
- If you must make an exception and trans­
port a fuel container, note the fo llowing:

lL t:0 ....
"' ......
"' .... 0 0 :c ' -Never f ill the fuel container with fuel
while it is in or on the vehicle. Stat ic elec­
tr icity is discharged when filling which can
cause the fuel vapors to ignite and in­
creases the r isk of an explos ion.
- Always p lace a fuel container on the
ground before fi lling.
- Always hold the fuel nozzle comp letely in
the fuel container when f il li ng .
- If the fuel container is made of metal, the
fuel nozzle must always be in contact with the conta iner when filling it w ith fuel. Th is
prevents static electr ic ity from discharg­
ing.
- Never sp ill fuel in the veh icle or the lug­
gage compartment. Evaporated fue l is ex­
p losive and increases the risk of serio us in­
jury or dea th.
- Follow legal requir ements when using,
sto ring and transpor ting fue l contai ners .
- M ake sure the fuel conta iner confo rms to
i nd ust ry st anda rds (ANSI/AS TM F852 -86).
(D Note
- Remove spilled fuel from vehicle paint im­
mediate ly, because it can damage paint.
- Never dr ive unti l th e fuel tank is comp letely
empty . The ir regular supply of fuel that re­
su lts from that ca n caus e engine misfires.
U ncomb usted fuel w ill enter the exha ust
system a nd i ncre ase the risk of damage to

Checking and Filling
If you must add coolant, use a mixture of water
and coolant additive . Mixing the coolant additive
with distilled water is recommended.
Coolant additive
The coolant additive is made of anti-freezing and
corros ion protection agents. Only use the follow ­
ing coo lant additives .
Coolant additive Specification
Gl2evo
TL 774 L
Gl2++ TL 774 G
Gl3
TL 774 J
These additives may be mixed wi th each othe r.
The amount of coo lant additive that needs to be
mixed with water depends on the climate where
the vehicle will be operated. If the coolant addi ­
tive percentage is too low, the coo lant can free ze
and damage the engine.

@ Note
-Before the start of winter, have an author­
ized Audi dealer or authorized Audi Service
Faci lity check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. This is especially important
when driving in colder climates .
-If the appropriate coolant additive is not
available in an emergency, do not add any
other addit ive for risk of damaging the en­
g ine . If this happens, only use water and re­
store the correct mixture ratio with the
specified coolant additive as soon as possi­ ble.
-Only refill with new coolant.
-Radiator sealant must not be mixed w ith
the coolant.

Checking the engine coolant level
~ Park the vehicle on a level surface .
~ Switch the ignit io n off.
~ Read the coolant level on the coolant expansion
tank ~ page 2 74. The coolant leve l must be be­
tween the MIN and MAX markings when the en­
gine in co ld. When the engine is warm it can be
slightly above the MAX marking,
Adding coolant
Requirement: there must be a residual amount of
coolant in the expansion
tank ~(©) .
~ Let the engine cool down .
~ Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockwise
~.&. -
~ Add coo lant mixed in the correct ratio
~ page 277 up to the MAX marking.
~ Make sure that the f luid level remains stable.
Add more coolant if necessary .
~ Close the cap securely .
Coo lant loss usually indicates there is a leak . Im ­
mediate ly drive your vehicle to an authorized
Audi dealer or authorized Audi Service Fac ility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant bo iling t hrough overheat ing
and being pushed out of the cooling system .

Emergency assistance
There are some restrictions on the use of the
spare tire. The spare tire has been designed spe­
cifically for your type of vehicle. Do not replace it
with the spare tire from another type of vehicle.
There are different types of spare tires available
depending on the equipment
c::> page 320.
Removing the spare tire
• Lift the cargo floor by the plast ic ha ndle
c::> fig. 282.
• Hook the hand le into the luggage compartment
weathe r strip.
• Turn the handwheel counter-clockwise and re-
move it.
• Remove the spare tire.
Snow chains
For technical reasons, the use of snow chains on
the compact spare tire is not permitted.
If you have to drive w ith snow chains and a front
tire fails , mount the spare t ire in place of a rear
tire . Install the snow chains on the rear tire that
you removed, and install that in place of the
front tire that failed.
A WARNING
-After installing a spare tire, the tire pres­ sure must be checked as quickly as possible.
- Do not drive faster than 50 mph (80 km/h)
with a compact spare tire. Driving faster
than that increases the risk of an accident.
- To reduce the risk of an accident, avoid full­
throttle acceleration, heavy braking, and
fast cornering with the compact spare t ire.
- To reduce the risk of an accident, never drive
with more than one compact spare tire.
- Norma l summer or winter tires must not be
mounted on the compact spare wheel rim.
A WARNING
- Never use the spare tire if it is damaged or if
it is worn down to the tread wear indicators.
- If the spare tire is more than 6 years old, use it only in an emergency and with ex­
treme caution and careful dr iving .
- The spare tire is intended only for tempora­
ry and short-term use.
It should be replaced
320
as soon as possible with the normal whee l
and tire.
- For technical reasons, the use of tire chains
on the spare tire is not permitted. If it is
necessary to drive with tire chains, the spare
wheel must be mounted on the front axle in
the event of a flat in a rear tire . The newly
ava ilable front wheel must then be installed
in place of the rear wheel w ith the flat tire.
Installing the tire chain before mounting
the wheel and tire is recommended.
- Loose items in the passenger compartment
can cause serious personal injury during
hard braking or in an accident. Never store
the inflatable spare tire or jack and tools in
the passenger compartment .
