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 powerplant 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
lubrication 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

i m medi at ely.•
Changing brake fluid
Have the brake fluid changed by an experienced techni­
cian.
Brake fluid absorbs moisture from the ai r. If the water content in the
brake fluid is too high, corrosion in the brake system may result
after a period of time. The boiling point of the brake fluid wil l also
decrease considerably and decrease braking performance .
Therefore, the brake fluid must be changed
e ver y two years. Always
use new brake fluid which conforms to Federa l Motor Vehicle Stan ­
dard "FMVSS 116 DOT 4" .
The brake fluid reservoir can be difficu lt to reach , therefore, we
recommend that you have the brake fluid changed by your autho­
rized
Audi d ealer. Your dealer has the correct tools, the right brake
fluid and the know-how to do this for you.
& WARNING
• Bra ke fluid i s poisonous . It mu st be stored on ly in the close d
ori ginal container out of the rea ch of children!
• Bra ke fa ilure can result from old or inappropri ate brake fluid .
Observe the se pre caution s:
- Use o nly brake fluid that meets SAE spe cifi ca tion
J 170 3 and
c onform s to Fed era l Moto r Vehic le Sta nda rd 116 . Always c heck

and is more difficult to stop. Overloading can not only lead to loss
of vehicle control, but can also damage important parts of the
vehicle and can lead to sudden tire failure, including a blowout and
sudden deflation that can cause the vehicle to crash.
Your safety and that of your passengers also depends on making
sure that load limits are not exceeded. Vehicle load includes every ­
body and everything in and on the vehicle. These load limits are
technically referred to as the vehicle's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the weight of the basic vehicle, all factory
installed accessories, a full tank of fuel, oil, coolant and other fluids
plus maximum load. The maximum load includes the number of
passengers that the vehicle is intended to carry ("seating capacity")
with an assumed weight of 150 lbs (68 kg) for each passenger at a
designated seating position and the total weight of any luggage in
the vehicle. If you tow a trailer, the weight of the trailer hitch and the
tongue weight of the loaded trailer must be included as part of the
vehicle load.
The
Gross Axle Weight Rating ("GAWR") is the maximum load that
can be applied at each of the vehicle's two axles.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating
are listed on the safety compliance sticker label located either on
the driver's side B-pillar or on the inside of the fuel filler flap. Your
Audi has 5 seating positions, 2 in the front and 3 in the rear for total
seating capacity of 5. Each seating position has a safety belt
=>
page 137, "Safety belts".
The fact that there is an upper limit to your vehicle's Gross Vehicle
Weight Rating means that the total weight of whatever is being
carried in the vehicle (including the weight of a trailer hitch and the
tongue weight of the loaded trailer) is limited. The more passengers
in the vehicle or passengers who are heavier than the standard
weights assumed mean that less weight can be carried as luggage.
The tire pressure label on your Audi also lists the maximum
combined weight of all of the occupants and luggage or other cargo that the vehicle can carry.
For the location of the label=>
page 247,
fig. 180.
& WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or
other accident, serious personal injury, and even death.
• Carrying more weight than your vehicle was designed to carry
will prevent the vehicle from handling properly and increase the
risk of the loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe distance.
• Tires on a vehicle that has been overloaded can fail suddenly,
including a blowout and sudden deflation, causing loss of control
and a crash.
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehicle's Gross Vehicle Weight Rating. •
Determining correct load limit
Use the example below to calculate the
total weight of the passengers and luggage or other things that you plan to
transport so that you can make sure that
your vehicle will not be overloaded.

Tires and wheels -_______________ _____.
Incorrect wheel alignm ent
Inc orrect wheel alignment ca n cause excessive tire wear, impairing
the safety of the vehicle . If tires show excessive wear, have the
whee l alignment chec ked by an autho rized A udi deale r or qu alifie d
wor kshop .
All Wheel Drive
Vehicles with quattro® must always have tires of the same size,
co nst ructi on an d tread type . For detail s see =>
page 196 .
& WARNING
Sudden tire failure can lead to lo ss of control, a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indi cators.
• Worn tire s are a safety hazard , they do not grip well on wet
roads and increase your risk of "hydroplaning " and loss of control.
• Always keep chemicals that can cau se tire damage , such a s
grease , oil , gasoline and brake fluid away from tires.
• Tires age even if they are not being used and can fail suddenly ,
especially at high speeds . Tire s that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds .
• Never mount used tire s on your vehicle if you are not sure of
their "previou s hi story. " Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failu re and loss of vehi cle control. •
