Engine oil
Engine oil specifications
The engine oil used must conform to exact speci­
fications.
The service interval display in the instrumen t
cluster of your vehicle will inform you when it is
time for an o il change. We recommend that you
have your oi l changed by an authorized Audi Se rv­
ice Advisor.
If you must add oil between oil changes, use an
oi l that matches the Audi oil quality standard
listed on the sticker. The sticker is located at the
front of the eng ine compartment

Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­
tion .
Before you check anyth ing in the eng ine compart­
ment,
a lways rea d and heed all WARNINGS¢ &
in Working in the engine compartment on
page 271.
The engine oil must be changed according to the intervals specified in your Warranty
& Mainte­
nance booklet . This is very important because the
lubricat ing propert ies of oil diminish gradually
during normal vehicle use.
Under some circumstances the engine oi l should
be changed more frequently. Change oil more of­
ten if you drive mostly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traffic condit ions, or have your vehi­
cle where temperatures remain below freezing
for extended periods .
Detergent additives in the oil will make fresh oil
look dark after the engine has been running for a
short time . This is normal and is not a reason to
change the oil more often than recommended .
Because of the problem of proper disposal, along
with the special tools and necessary expertise re­
qu ired, we strongly recommend that you have
your oil changed by an authorized
A ud i d ea ler or
a qualified service station .
If y ou choo se to change yo ur o il y o urse lf, please
note the following important information:
A WARNING
To red uce the risk of personal injury if you
must change the engine oil in your veh icle
yourself:
- Wear eye protection .
- To reduce the risk of burns from hot engine
o il, let the eng ine cool down to the touch.
-
- When removing the o il drain plug with your
fingers, stay as far away as poss ible. Always
Ch eck ing and Filling
keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one large enough to hold at
least the total amount of oil in your engine.
- Engine oil is poisonous. Keep it well out of the reach of children.
- Continuous contact with used engine oil is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water .
CI) Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adversely affect your Audi limited New Vehi­
cle Warranty.
® For the sake of the environment
- Before chang ing your oi l, first make sure
you know where you can properly d ispose of
the used oil.
- Always dispose of used engine o il properly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine o il by tak ing it to a used
eng ine oil collection fac ility in your area, or
contact a service station .
Cooling system
Coolant
The engine cooling system is filled with a mixture
of purified water and coolant additive at the fac­
tory. This coolant must not be not changed .
T he coo lant level is monitored through the. in­
dicator light¢
page 20. However, we do recom­
mend occasionally checking the coolant leve l
manually.
If you must add coolant, use a mixture of wate r
and coolant additive . Mixing the coolant additive
with dist illed water is recommended.

The coolant additive is made of anti-freezing and
corrosion protection agents. Only use the fo llow­
ing coolant additives .

These additives may be mixed with each other.
The amount of coolant additive that needs to be
mixed w ith water depends on the climate where
the vehicle will be operated . If the coolant addi­
tive percentage is too low, the coo lant can freeze
and damage the engine.

(D Note
-Before the start of winter, have your author­
ized Audi dealer or authorized Audi Service
F ac ility check if the coolant additive in you r
vehicle matc hes the percentage appropriate
fo r the clim ate. This is espe cially important
when driving in colder climates .
-If the appropriate coolant addi tive is not
available in an emergency, do not add any
other additive for risk of damaging 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 coo lant.
- Radiator sealant must not be mixed with
the coo lant.

.,. Switch the ignit ion off.
.,. Read the coolant level on the coolan t expansion
tank
¢page 274. The coolant leve l must be be­
tween the M IN and MAX markings when the en­
gine in cold . When the engine is warm it can be
slightly above the MAX marking .
Adding coolant

.. Add coolant mixed in the correc t ratio
~ page 277 up to the MAX marking.
.,. Make sure that the fluid level remains stable.
Add more coolant if necessary .
.,. Close the cap securely .
Coo lant loss usually indicates there is a leak . Im­
med iate ly 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 leak ing, a loss can come
from the coolant boiling through overheat ing
and being pushed ou t of the cooling system .

_& WARNING
-The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the engine is hot. This increases the
risk of burns .
- The coolant add itive 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 sw itch
on even if the ignition is switched off, which
increases the risk of injury.
CD 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 driv ing. See an authorized Audi deal­
er or authorized Audi Service Facility for assis­
tance.

made of steel wires, wrapped or
reinforced by ply cords and that is
shaped to fit the rim .
Bead separation
means a breakdown of the bond
between components in the bead.
Cord
means the strands forming the
plies in the tire.
Cold tire inflation pressure
means the tire pressure recom­
mended by the vehic le manufac­
turer for a tire of a des ignated
size that has not been driven for more than a couple of miles (kilo­
meters) at low speeds in the
three hour period before the tire pressure is measured or adj usted.
Curb weight
means the weight of a motor ve­
hicle w ith standard equipment in ­
cluding the maximum capacity of
fuel, oil, and coolant, air condi ­
tioning and additiona l weight of
op tional equipment.
E x tra load tire
means a tire des igned to operate
at higher loads and at h igher in -

flation pressures than t he corre­
spond ing standa rd tire. Extra load
tires may be identified as "XL",
"xl" , "EXTRA LOAD" , or "RF" on
the sidewall.
Gross A xle Weight Rating
("GAWR ")
means the load-carrying capacity
of a single axle system , measured
at the ti re-gro und interfaces.
Gross Vehicle Weight Rating
("GVWR")
means the max imum total loaded
weight of the vehicle .
Groove

Wheels
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of
150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion 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 includ­
ed 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 fact that there is an upper
limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
296
carried in the vehicle (including
the weight of a trailer hitch and the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as l uggage .
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar
¢ page 293,
fig. 267.
.&_ WARNING
-
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal 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.
