- The engine oi l consumption may be up to
0.5 quart/600 miles (0.5 liter/1,000 km),
depending on driving style and operating
conditions. In RS models, the oil consump­
tion may be up to 1 qt/600 mi (0.8 L/ 1,000 km). Consumption may be higher
during the first 3,000 miles (5,000 km). Be­
cause of this, the engine oil level must be
checked regular ly.
It would be best to check
each time you ref uel your veh icle and befo re
l ong d rives.
Changing the engine oil
We recommend that hove your oil changed by on
authorized Audi dealer or a qualified service sta­
tion .
Before you check a nyth ing in the eng ine compart­
ment,
alway s re ad and heed all WARNING S 9 &.
in Working in the engine comportment on
page 199.
The engine oil must be changed according to the
intervals specified in you r Warranty
& Mainte­
n ance booklet. This is very impo rtant because the
l ub ricating properties of oil diminish gradually
during normal vehicle use.
Unde r some ci rcumstances the e ngine o il should
be cha nged more frequently . Change oil mo re of­
ten if yo u drive mostly short distances, operate
the vehicle in dusty areas or under predominant ly
stop-and-go traffic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
l ook dark after the engine has been running for a
short time. Th is is normal and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposa l, along
with the special tools and necessary expertise re­
q ui red, we strongly recommend that you have
your oil changed by an authorized
A ud i dealer or
a qualified service station.
If you choose to chang e your o il your self, please
note the following important information:
Ch eck ing and Filling
A WARNING
To reduce the risk of persona l injury if you
must change the eng ine oil in you r vehicle
yourself:
- Wear eye protect ion.
-
- To reduce the r isk of burns from hot engine
oil, let the engine cool down to the touch.
- When remov ing the oil drain plug w ith your
f ingers, stay as far away as possible. Always
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 la rge enough to hold at
least the tota l amount of oi l in you r engine .
- Engine oil is poisonous. Keep it we ll out of
the reach of children.
- Continuous contact with used engine o il is
harmf ul to your skin. Always protect your
skin by washing oil off thoroughly with soap
and wate r.
Q) Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adverse ly affect you r 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 e ngine o il properly .
Do not dump it on ga rden soil, wooded
areas, into open streams o r down sewage
dra ins.
- Recycle used e ngine o il by ta king it to a used
eng ine oil collection fac ility in yo ur area, or
c ont act a se rvice station.
Cooling system
Coolant
The eng ine cooling system is fi lled w ith a mixture
of purified water and coolant additive at the fac-
tory. This coolant m ust not be not changed . .,._

Check ing and F illing
The coolant leve l is monitored through the. in­
dicator light ¢
page 14. However, we do recom­
mend occasionally check ing the coo lant level
manually.
I f you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with d istilled water is recommended.
Coolant additiv e
The coolant addi tive is made of anti-freezi ng and
corros ion protection agents. Only use the fo llow­
ing coolant additives . These additives may be
mixed with each other.
Coolant additive Specification

TL 774 G
The amount of coolant add itive 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 coolant can freeze
a nd damage the engine.

Note
-Before the start of winter, have your author­

Fac ility check if the coolant additive in you r
vehicle matches the percentage approp riate
fo r the clim ate. Thi s is especially important
when driving in co lder climates .
- If the approp riate coolant additive is not
available in an emergen cy, do no t add any
other additive. You cou ld damage the en ­
gine. If this happens, only use water and re­ store the correct mixture ratio with the
spec ified coolant additive as soon as possi­
ble.
- Only refill with new coo lant.
- Radiator sealant must not be mixed w ith

_& 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 .

Facility.
A WARNING
-
- If the brake fluid level is below the MIN
marking, it can impair the braking effect
and driving safety, which increase the risk of
an accident . Do not continue dr iving . See an
author ized Audi dealer or author ized Audi
Service Facility for assistance.
- If the brake fluid is old, bubbles may form
in the brake system dur ing heavy braking .
This would impair braking performance and
driving safety, which increases the r isk of an
accident.
- To ensure the brake system functions cor­
rectly, only use brake fluids that comply
with VW standard 50114 or FM VSS -116 DOT 4.
CD Note
-If the brake f luid level is above the MAX
marking, brake f luid may leak out over the
edge of the reservoir and result in damage
to the vehicle.
- Do not get any brake fluid on the vehicle
paint, because it wi ll corrode the paint.

Please note the important safe­
ty precautions regarding tire pressure ¢
page 221 and load
limits¢
page 224.
Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
224
tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­
sengers also depends on making
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

Weights
Gross Vehi cle We ight Rating
The G ross Veh icle Weight Rating (GVWR), and
the Gross Axle Weight Rating (GAWR) for front
and rear are listed on a sticker on the door jamb
on the driver's side.
The G ross Veh icle Weight Rating includes the
weight of the basic vehicle p lus full fuel tank, oi l
and coolant, p lus maximum load, which includes
passenger weight (150 lbs/68 kg per designated
seating position) and luggage we ight
c:> A .
Gross Axle Weight Rating
The Gross Axle We ight Rating is the max imum
l oad that can be applied at each axle of the vehi ­
cle
c:> &, .
Vehicle capacity weight
The vehicle capac ity we ight (max . load) is listed
e ithe r o n the dr iver's side 8-pilla r or inside the
fuel filler f lap .
A WARNING
-
-The actual Gross Ax le Weight Rating at the
front and rear axles sho uld not exceed the
permissible weights, and their comb inat ion
must not exceed the Gross Vehicle We ight
Rating.
- Exceeding perm iss ible weight ratings can
result in vehicle damage, acc idents and per­
sonal inj ury .
Dimensions
Techn ical data
(D Note
- The vehicle capacity weig ht figures apply
when the load is d istributed evenly in the
vehicle (passengers and luggage). When
transport ing a heavy load in the luggage
compartment, carry the load as near to the
rear axle as possible so that the vehicle's
hand ling is no t impa ired .
- Do not exceed the maximum perm iss ible
ax le loads or the maximum gross vehicle
we igh t. A lways remember that the vehi cle's
hand ling will be affected by the extra load.
T he refore, adjust your speed acco rd ingly.
- Always observe lo cal regulations.
