Safety belts
Only well-maintained safety belts work reliably when
needed.
- Keep belts clean.
- For cleaning, use a mild soap and water solution. Let
belts dry thoroughly and away from direct sunlight.
- Do not allow inertia reel safety belts to retract before
they are completely dry.
- Check the condition of your safety belts
regularly.
Heavily soiled safety belts may not retract properly.
& WARNING
Damaged safety belts can break in a crash .
• Anything that might damage your safety belts could mean that
you and your passengers would not be adequately protected in an
accident.
• Safety belt performance depends on correct installation. Never
remove belts from the vehicle to clean them .
• Do not use chemical cleaning agents, bleach or dyes. They have
corrosive properties which weaken the webbing.
• When cleaning your safety belts, inspect them for damage. If
you discover damage, see your authorized Audi dealer.
• Always read and heed all WARNINGS and other information
=:, page 206. •
Engine compartment
Be especially careful when cleaning the engine compart­
ment.
Always switch off the ignition before cleaning the engine =:> &.
Plenum panel
Remove leaves from the plenum panel in front of the windshield
under the engine hood. This prevents the water drain holes from
becoming blocked, and it prevents debris from entering the vehicle
interior through the heating and ventilation ducts .
Corrosion protection
The engine compartment and transmission have been corrosion­
protected at the factory.
Good anti-corrosion treatment is very important, particularly in the
winter. If the vehicle is frequently driven on salt treated roads, the
entire engine compartment and plenum panel should be thor ­
oughly cleaned at the end of winter and retreated to prevent salt
damage. At the same time, the underside of the vehicle should be
washed as well.
If the engine compartment is cleaned at any time with grease
removing solutions
3l, or if you have the engine washed , the anti­
corrosion treatment is almost always removed as well . It is therefore
essential to have a long-lasting corrosion protection reapplied to all
surfaces, seams, joints and components in the engine compart ­
ment.
& WARNING
Be aware: The engine compartment of any motor vehicle is a
potentially hazardous area.
• Before working in the engine compartment, be sure to read the
information
=:> page 217 . .,,_
31 Use only the correct cleaning solutions. Never use gasoline or diesel fuel.

& WARNING
To reduce the ri sk of personal inju ry if you mu st change the engine
oil in your vehicle your self:
• Wear eye prote ction .
• To reduce the ri sk of bu rn s from hot engine oil , let the engine
c ool down to the tou ch .
• When remo ving th e oil dr ain pl ug w ith your fing ers, s tay a s fa r
a w ay as po ssibl e. Alw ays keep your forearm p arallel to the grou nd
to help prevent hot oil from running down your arm .
• Drai n the oil into a container de signed for th is purpose , one
l a rg e enough to hold at le ast the tot al a mount of oil in your eng ine .
• Engine oil is poi sonou s. Keep it well out of the rea ch of children .
• Continuous contact with used engine oil i s harmful to your
skin. Always prote ct your skin by wa shin g oil off thoroughly with
s oap and water .
0 Note
Never mix oil additives with your engine oil. These additives can
damage your engine and adversely affect your Audi New Vehicle Limited Warranty .
~ For the sake of the environment
• Before changing your oil, first make sure you know where you
can proper ly dispose of the used oil.
• Always dispose of used engine oil properly . Do not dump it on
garden soil, wooded areas, into open st reams or down sewage
drains .
• Recycle used engine oi l by taking it to a used engine oi l collec ­
tion facility in your area, or contact a service station .•
Engine cooling system
Coolant
The engine coolan t perf orms two func tions: it keeps the
engine from overheating an d it protects the engine from
freezing in the winter.
The cooling system is sealed and general ly requires litt le attention.
The coo ling system has been fi lled at the factory with a permanent
coo lant which does not need to be changed. The coolant consists of
a mixture of water and the manufacturer's glycol -basedcoolant
additive G12+ + antifreeze with anti corrosion additives (50% for USA
models; 60% for Canadian mode ls) . This mixture both assures the
necessary frost protection and protects metal components in the
engine's cooling system from corrosion and scaling. It also raises
the boil ing point o f the coolant.
D o not reduce the concentration of the coo lant in the summer by
adding pla in water.
Th e proporti on of coolant additive must b e at
l e as t 50 % but not more than 60 %
to maintain antifreeze protection
and cooling efficiency . If the coolant frost protect ion is too low, the
coo lant could freeze and damage the vehicle heating and engine
coo ling system.
For year-round driving, antifreeze is added at the factory for temper ­
atures down to :
• -31 °F ( -35 °C) USA
• - 40 °F ( - 40 °C) Canada .
You can mix the G12 ++ coolan t additive with other additives G12 + or
G12. Always check with your authorized Audi dealer.
& WARNING
Bef ore you che ck anything in the engine compartment , alwa ys
read and heed all WARNING S
~ & in "Working in the engine
c ompartment " on
page 225.

Checking and filling -
---------------------=----"=---------
0 Note
• Before winter sets in, have the coolant checked to see if the
coolant additive in your vehicle is sufficient to meet the climate
conditions. This is especially important if you live in a region where
the winter is extremely cold. If necessary, increase the proportion of
coolant additive to 60%.
• When adding coolant additive to your cooling system,
remember:
-We recommend using only coolant additive G12+ + (check the
label) for your vehicle. This coolant additive is available at autho­
rized Audi dealers. Other types of antifreeze can significantly
reduce corrosion protection . The resulting corrosion can cause a
loss of coolant and serious engine damage .
• Do not add any type of radiator leak sealant to your vehicle's
engine coolant. Adding radiator repair fluid may adversely affect the
function and performance of your cooling system and could result
in damage not covered by your New Vehicle Limited Warranty .•
Checking the engine coolant level
The engine coolant level can be checked with a quick
glance.
Fig . 175 Engine
compartment : coolant
expansion tank
Before you check anything in the engine compartment,
always read and heed all WARNINGS==> & in "Working in
the engine compartment" on
page 225.
Turn off the ignition.
Read the engine coolant level from the coolant expan­
sion tank==> fig. 175. With a cold engine, the coolant level
should be between the "min" and "max" markings. When
the engine is warm, the level may be slightly above the
" max" marking.
The location of the coolant expansion tank can be seen in the
engine compartment illustration=>
page 226.
To obtain an accurate reading, the engine must be switched off.
The expansion tank in your vehicle is equipped with an electric
coolant level sensor.
When the coolant level is too low, the warning light in the Auto­
Check System =>
page 30will blink until you add coolant and the
level has been restored to normal. Even though there is an electric
coolant level sensor, we still recommend you check the coolant level
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling system. In the event
of coolant loss, the cooling system should be inspected immedi­
ately by your authorized Audi dealer. It is not enough merely to add
coolant.
In a
sealed system, losses can occur only if the boiling point of the
coolant is exceeded as a result of overheating.
0 Note
Do not add any type of radiator leak sealant to your vehicle's engine
coolant. Adding radiator repair fluid may adversely affect the tune- _..
