• Always make sure that the side airbag can inflate without
interference:
-Never install se at covers or replacement upholstery over the
front seatbacks that have not been specifically approved by
Audi .
- Never use additional seat cushions that cover the areas
where the side airbags inflate .
- Damage to the original seat covers or to the seam in the area
of the side airbag module must always be repaired immedi
ately by an authorized Audi dealer.
• The airbag sy stem can be activated only once. After an airbag
has inflated, it must be replaced by an authorized Audi dealer or
qualified technician who has the technical information , training
and special equipment necessary.
• The airbag sy st e m can be deployed only onc e. After an airbag
has been deployed, it must be replaced w ith new replacement
parts de signed and approved es pecially for your Audi model
version . Replacement of complete airbag systems or airbag
components must be performed by qualified workshops only.
Make sure that any airbag service action is entered in your Audi
Warranty
& Maintenance booklet under AIRBAG REPLACEMENT
RECORD.
• In accidents when an airbag is deployed, the vehicle battery
separates the alternator and the starter from the vehicle electrical
system for safety reason s with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circu it interrupter must only be
performed by a qualified dealer -risk of an a ccident!
- If the vehicle or the circu it interrupter is scrapped, all appli

and for the different models of the same kind of child restraint
offered by child restraint manufacturers.
The weight ranges for the individual types, makes and models of ch ild
restraints that the NHTSA has specified in the Safety Standard
together with the weight ranges of typical infants and typical 1 year
old child have been stored in the control unit of the Advanced Airbag
System. When a child restraint is being used on the front passenger
seat with a typical 1 year-old chi ld, the Advanced Airbag System
compares the weight meas ured by the weight sensing mat with the
information stored in the electronic control unit .
The electronic contro l unit a lso registers the tension on the front
passenger safety belt. The tension on the safety belt for the front
passenger seat will be different for an adult who is properly using the
safety belt as compared to the tension on the belt when it is used to
attach a child restraint to the seat . The sensor below the latch for the
safety belt for the front seat passenger measures the tension on the
belt. The input from this sensor is then used with the weight to
"decide", whether there is a child restraint with a typical 1 year-old
child on the front passenger seat and whether or not the airbag must
be turned off .•
Child restraints and Advanced Airbags
Regardless of the child restraint that you use, ma ke sure that it has
been certified to meet United States Federal Motor Vehicle Safety
Standards and has been ce rtified by its manufacturer for use with an
airbag . Always be sure that the child restraint is properly installed at
one of the rear seating positions. If in exceptional circumstances you
must use it on the front passenger seat, carefully read all of the infor
mation on ch ild safety and Advanced Airbags and heed all of the
app licab le WARNINGS. Make certain that the child restra int is
correctly recognized by the weight-sensing mat inside the front
passenger seat, that the front passenger airbag is turned off and that
the airbag status is always correctly signaled by the
PASSENGER AIR
BAG OFF
light.
Controls and equip ment Safety first Vehicle operation
Many types and models of child restra
ints have been available over
t he years, new models are introduced reg ularly incorpo rating new
and improved designs and older models are taken out of product ion.
Chi ld restraints are not standardized. Child restraints of the same
type typ ically have d ifferent weights and sizes and differe nt 'foot
prints,' the size and shape of the bottom of the child restraint that
sits on the seat, when they are installed on a vehicle seat . These
differences make it virtually impossib le to certify compliance with

Driving and environment
------------------------------------------------'
depending upon vehicle load and speed, road and weather conditions,
trip length, etc. •
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are accelerating .
-Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are accelerating. If you antici
pate what is going to happen next, you will need to brake less and,
thus, accelerate less. Let the vehicle coast whenever possible - for
example when you see that the next traffic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
- Try and keep well below your car's maximum speed.
Accelerating gently reduces fuel consumption, engine wear, and does
not disturb the environment .
Fuel consumption, exhaust emissions and eng ine noise increase
disproportionately at high speeds . If you drive at approximately three
quarters of top speed, fuel consumption will be reduced by one half.
Never drive faster than the posted speed limit and weather condi
tions permit. •
Reducin~ unnecessary idling
Even when your car is just idling it burns up fuel.
-Shut the engine off when you are not driving the vehic le .
- Do not warm up the vehicle by letting the engine run at
idle.
Controls and equip ment Safety first Vehicle operation It makes sense to shut off the engine in traffic jams, when waiting for
trains to pass at railroad crossings, or at traffic lights that have long
waits on red. Turning the engine off for just 30 -40 seconds saves
more fuel than is burned starting the engine again .
It takes a long t ime for the engine to warm up fully when it is running
at idle. However, wear and noxious emissions are especia lly high
when the eng ine is warming up. So you should dr ive away as soon as
you start the engine and avoid running at high rpms while the engine
is still warming up.
0 Note
Do not leave engine idling unattended after starting . If warning
lights should come on to indicate improper operation, they would go
unheeded. Extended idling also produces heat, which could result in
overheat ing or other damage to the vehicle or other property. •
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel .
- Have your vehic le serviced at regular intervals .
By having your vehicle regularly serviced by an authorized Audi dealer
helps to ensure that it runs properly and economically . The condit ion
of your vehicle not on ly affects its safety and ability to hold its val ue,
it also affects fuel consumption.
Check your oil each time you fill your tank.
Th e amount of oil used is related to engine load and speed.
It is normal for the oil consumption of a new engine to reach its
lowest value after a certain mileage has been driven.
You must dr ive your veh icle about 3,000 miles (5,000 kilometers)
before you can properly assess oi l consumption .
Thi s also applies to fuel consumption and eng ine output.

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the right kind of oil.
The engine in your Audi is a sophisticated power plant that was built
to exacting specifications. This engine needs the right kind of engine
oil that meets specifications regarding quality and viscosity so that it
can run smoothly and reliably. Choosing the right oil and changing oil
within the time and mileage intervals printed in your vehicle's
Warranty
& Maintenance booklet matters a lot more today than it did
years ago. Audi has developed a special quality standard for engine oil
that will help assure that your vehicle's engine will get the lubrication
it needs for proper operation.
Modern engine lubrication has taken a quantum leap in the last few
years. Many synthetic oils available today provide better engine lubri
cation that can outlast traditional petroleum-based oils, making
them a smart choice for use throughout the life of your Audi.
Whether you use synthetic or petroleum-based engine oil, the oil that
you use must conform to Audi's oil quality standard VW 502 00 to help keep your vehicle's engine running smoothly and help prevent
the formation of harmful deposits, sometimes called "sludge", that
over time can lead to expensive repairs.
Safety first
At the time of printing, engine oils available in the U.S. and Canada
that meet the exacting specifications of Audi oil standard VW 502 00
are synthetic engine oils. This does not mean, however, that every
synthetic engine oil will meet Audi oil standard VW 502 00. So always
be sure that you use an approved oil.
To help prevent the formation of harmful deposits use only oil with
the following specifications printed on the oil container:
Audi oil standard VW 502 00
Oil container labels may carry the specification singly or in combina
tion with other designations and oil quality standards.
Viscosity
Engine oils are graded according to their viscosity. The proper
viscosity grade oil for your engine depends on climactic or seasonal conditions where you drive. You can use oil with a viscosity grade of
SAE SW40 across all temperature ranges for normal driving condi
tions.
However, if engine oil viscosity grade SAE SW40 is not available, you
can also use viscosity grade SAE SW-30 or SAE OW-40 as long as it
meets Audi oil quality standard VW 502 00 specifications.
Because engine oil that meets the Audi oil standard may not be avail
able everywhere when you need it, we strongly recommend that you
always carry with you an extra quart (liter) of oil that expressly
conforms to the VW 502 00 specification, in case you have to top off
the oil while on the road.
Only if the level of the oil is at or below the minimum mark - and no
oil that expressly conforms to Audi oil standard VW 502 00 specifica
tions is available -may you top off with a high quality engine oil, pref
erably synthetic-based, that meets ACEA A3, ACEA AS or ACEA BS or
API SL specifications, but even then, only in viscosity grades SAE SW-
40, SAE SW-30, or SAE OW-40. However, during the entire time
between oil change intervals, never top off with more than a total of
0.5 qt/liter engine oil that does not conform to Audi oil specification
vw 502 00. ..

The fluid level may drop slightly after some time due to the auto
matic adjustment of the brake pads. This is not cause for alarm.
If the brake flu id level falls considerably below the "MIN " mark, the
brake warning/indicator light (U.S. models:
BRAKE , Canadian mode ls:
{(j)) ) will come on=> page 18 and=> page 33. Do not continue to
ope rate the vehicle. The complete brake system should be thorough ly
checked by an authorized Audi dealer or qualified workshop and the
cause corrected. If the brake fluid level is too low, the brake
wa rning/ind icator light will illuminate. Contact an authorized Aud i
dealer
immediately .
[I] Tips
The brake fluid reservoir is located undernea th the cover. •
Changing brake fluid
Hove the broke fluid changed by on experienced techni
Clon.
Brake fluid absorbs moisture from the air. If the water content in the
brake fl uid is too high, corrosion in the brake system may result after
a period of time. The boiling point of the brake fluid will also decrease
considerably and decrease braking performance.
Therefore, the brake flu id must be changed
every two years. Always
use new brake fluid which conforms to Federal Motor Vehicle Stan
dard "FMVSS 116 DOT 4".
The brake fluid reservoir can be difficult to reach, therefore, we
recommend that you have the brake fluid changed by your authorized
Audi dealer. Your dealer has the correct tools, the right brake fluid
and the know-how to do this for you .
& WARNING
• Brake fluid is poi sonous. It must be stored only in the closed
original container out of the reach of children!
Safety first
& WARNING (continued )
• Brake failure can result from old or inappropriate brake fluid.
Observe these precautions:
-Use only brake fluid that meets SAE specification
J 1703 and
conforms to Federal Motor Vehicle Standard 116. Always check
with your authorized Audi dealer to make sure you are using
the correct brake fluid . The correct type of brake fluid is also
indicated on the brake fluid reservoir.
- The brake fluid must be new. Heavy use of the brakes can
cause a vapor lock if the brake fluid is left in the system too
long. This can seriously affect the efficiency of the brakes as
well as your safety. This could result in an accident .
0 Note
Brake fluid will damage the paint of your vehicle.
ffi For the sake of the environment
Because of the prob lem of proper disposal of brake fluid as well as
th e special tools required and the necessary expertise, we recom
mend that you have the brake fluid changed by your author ized Audi
dealer. •
Battery
General information
Under normal operating conditions, the battery in your Audi does not
need any maintenance . With high outside temperatures or long daily
drives we recommend that you have the electro lyte level checked by
an authorized Audi dealer or qualified workshop . The electrolyte leve l
should also be checked each t ime the battery is charged=> page 288.

vehicle at the tim e it was manufactured.
If you wish to improve comfort when operating the vehicle at
normal load (up to 3 occupants) , you can adjust tire pressures to
those specified for normal vehicle load. Before operating the
vehicle at maximum load, you must increase the tire pressures to
those specified for maximum vehicle load
=> &.
Bear in mind that the tire pressure monitoring system* ca n only
monitor the tire pressures you have stored. The system does not
recogn ize the load condit ion of your vehicle.
The effectiveness of the tire pressure monitoring system* wi ll be

and serious personal injury.
• Always u se tire s, rim s and wheel bolts that meet the specifica
tions of original factory -installed tires or other combinations that
have been specifically approved by the vehicle manufacturer.
• Tires age even if they are not being used and can fail suddenly,
e specially at high speed s. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speed s.
• Never mount used tires on your vehicle if you are not sure of
their "previous history ." Old u sed tires may have been damaged

tire failure and loss of vehicle control.
• All four wheels must be fitted with radial t ires of the same
type , size (rolling circumference ) and the same tread pattern .
Driving with different tires reduces vehicle handling and can lead
to a loss of control.
• If the spare ti re is not the same as the t ires that are mounted
on the vehicle -for example with winter tires -only use the spare
tire for a short period of time and drive with extra care. Refit the
normal road wheel as soon as safely possible .
• Never drive faster than the ma ximum speed for which the tires
on your vehicle are rated becau se tire s that are driven faster than
their rated speed can fail suddenly .
• Overloading tire s cau se heat build-up, sudden tire failure,
including a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properly inflated
and not over or unde rinflated.
• For technical reasons it is not always possible to u se wheels

& WARNING
Improperly tightened or maintained wheel bolts can become
loose causing loss of control, a collision and serious personal
injury .
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened.
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled, even
if tightened to the specified torque.
• Only use wheel bolts that belong to the rim being installed .
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss. If the tightening torque of
the wheel bolts is too low, they can loosen and come out when the
vehicle is moving. If the tightening torque is too high, the wheel
bolts and threads can be damaged and the wheel can become
loose.

The performance of low-aspect-ratio tires is particularly sensitive to
improper inflation pressure . It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pressure is regularly checked and maintained. Tire pre s
sures should be checked at least once a month and always before a
long trip~ pag e 297, "Ch ecking tire pre ss ur e".
