Applies to: Cabriolet/Sportback : The tether an­
chors for the rear seating positions are located
on the backside of the rear seatbacks
~ fig. 262.
A tether is a straight or V-shaped strap that at­
taches the top part of a child restraint to special
anchorage points in the vehicle .
T he purpose of the tether is to reduce the for­
ward movement of the child restraint in a crash,
in order to help reduce the risk of head injury
that could be caused by striking the vehicle inte­
rior .
Forward facing child restraints manufactured af­
ter September 1, 1999, are required by U .S. fed­
eral regulations to comply with new child head
movement performance requirements . Th ese
new performance requirements make a tether
necessary on most new child safety seats .

Audi recommends
~ castroL //g/:fl;[ff}g f'rf!J7.f'"«JD,'1A1.
Audi recommends Longlife high performance
engine oil from Audi Genuine Parts
Using the proper engine oil is important for the
functionality and s ervice life of the engine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
year .
(D Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet .
-Use only a high quality engine oil that ex-
pressly complies with the Audi oil quality
standard specified for your vehicle's engine .
Using any other oil can cause serious engine
damage.
-Do not mix any lubricants or other additives
into the engine oil. Doing so can cause en­
gine damage.
(D Tips
If you need to add oil and there is none availa­
ble that meets the Audi oil quality standard
your engine requires, you may add a total of
no more than 0.5 qt (0.5 l) of a high-quality
"synthetic"oil that meets the following speci­
fications.
-ACEA A3 or API SM with a viscosity grade of
SAE 0W-30, SAE 5W-30 or SAE 5W-40.
-For more information about engine oil that
has been approved for your vehicle, please

· Engine oil consumption
T he engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool oil of
its moving ports .
In order to provide effective lubrication and cool­
ing of internal engine components, all internal
combustion engines consume a certain amount
of oil. Oil consumption varies from engine to en­ gine and may change significantly over the life of
the engine . Typically, engines with a specified
break-in period
(see ¢ page 74) consume more
oil during the break-in period than they consume
after oil consumption has stabilized.
Under normal conditions, the rate of oil con­
sumption depends on the quality and viscosity of
the oil , the RPM (revolutions per minute) at
which the engine is operated, the ambient tem­ perature and road conditions. Further factors are
the amount of oil dilution from water condensa­
tion or fuel residue and the oxidation level of the
oil. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
ti me until replacement of worn components may
become necessary.
With all these variables coming into play, no standard rate of oil consumption can be estab­
lished or specified . There is no alternative to reg­
ular and frequent checking of the oil level , see
Note.
If the yellow engine oil level warning symbol II
in the instrument cluster lights up, you should
check the oil level as soon as possible
¢ page 321. Top off the oil at your earliest con­
venience
¢ page 321.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS
¢ page 316.
(D Note
Driving with an insufficient oil level is likely to
cause severe damage to the engine.
IJII,

Checking and Filling
When the engine is warm it can be slightly above the upper marking.
Adding coolant
Plug-in hybrid drive* : Your vehicle has two cool­
ant expansion tanks that are separate from each
other. The smaller of the two expansion tanks
must not be opened
¢ page 104. Read and fol­
low the important safety precautions ¢
A in
Coolant on page 105 .
Requirement: there must be a residual amount of
coolant in the expansion tank
¢ (D .
~ Let the engine cool down.
~ Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockwise
¢_&. .
~ Add coolant mixed in the correct ratio
¢page 323 up to the upper marking.
~ Make sure that the fluid level remains stable.
Add more coolant if necessary.
~ Close the cap securely.
Coolant loss usually indicates there is a leak . Im­
mediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected.
If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and being pushed out of the cooling system.
.,&. WARNING
The cooling system is pressurized and can be­
come very hot. To reduce the risk of burns
from hot coolant:
- Do not open the coolant expansion tank cap
when the engine is hot. This increases the
risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coolant tank cap with a large, thick cloth.
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure on the cap.
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the ex­
haust system or hot engine components.
324
The ethylene glycol in engine coolant can
catch fire under certain circumstances.
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children . There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
(D Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system and
damage the engine . If this is the case, do not
continue driving . See an authorized Audi deal­
er or authorized Audi Service Facility for assis­
tance.
- Before the start of winter, have an author­
ized Audi dealer or authorized Audi Service
Facility 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 additive. You could damage the en­
gine. 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 with the coolant.
· Radiator fan
The radiator fan switches on automatically by it­
self
An auxiliary electric radiator fan switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan
can continue running for up to 10 minutes
-even
with the ignition off.
It can even switch on again
later by
itself ¢.& , if .,..

vehicle is parked in intense su nlight .
_& WARNING
- To reduce the risk of personal injury never
touch the radiator fan .
- The auxiliary elect ric fan is temperature
contro lled and can switch on suddenly even
w hen the eng ine is not running.
- The auxiliary radiator fan switches on auto­ matically when the engine coo lant reaches a
