Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro
tects the engine from freezing in the winter .
The cooling system is sealed and generally re
quires little attention .
The cooling system has been filled at the fac
tory with a permanent coolant which does not
need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly
col-based coolant additive G12++ antifreeze
with anticorrosion additives (50% for USA
models; 60% for Canadian models). This mix
ture both assures the necessary frost protec
tion and protects metal components in the
engine's cooling system from corrosion and
scaling. It also raises the boiling point of the
coolant.
Do not reduce the concentration of the cool
ant in the summer by adding plain water.
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main
tain antifree ze protection and cooling efficien
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi
cle heating and engine cooling system.
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31 °F ( -3 5 °C) USA
- -40 °F ( - 40 °C) Canada.
You can mix the G12 ++ coolant additive with
other additives (G12+ or G12). Always check
with your authorized Audi dealer.
& WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS
~ .&. in Working in the engine
compartment on page 220.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
Checking and filling 22 7
your vehicle is sufficient to meet the cli
mate conditions. This is especially impor
tant if you live in a region where the win
ter is extremely cold. If necessary, in
crease the proportion of coolant additive
to 60% .
- When adding coolant additive to your
cooling system, remember :
- We recommend using only coolant ad
ditive G12++ (check the label) for your
vehicle. This coolant additive is availa
ble at authorized Audi dealers. Other
types of antifreeze can significantly re
duce corrosion protection. The result
ing corrosion can cause a loss of cool
ant and serious engine damage.
- Do not add any type of radiator leak seal
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.

Dr iving without va lve stem caps can cause
damage to the t ire va lves . To prevent this,
always make sure that factory installed
valve stem caps on all wheels are secu re ly
mounted on the va lve .
@) For the sake of the environment
Underinflated tires will a lso increase the
fue l consumption.
Tires and vehicle load limits
There are limits to the amount of load or
weight t hat any veh icle and any t ire ca n car ry.
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overload ing
can not on ly lead to loss of vehicle contro l,
but can a lso damage important parts of the
vehicle and can lead to sudden tire failure, in
cluding a blowout and sudden deflation that
can cause the ve hicle to crash.
Your safety and that of yo ur passenge rs a lso
depends on making sure th at load limits are
no t exceeded. Vehicle load includes everybody
and everyth ing in and on the vehicle. These
load limits a re tech nica lly referred to as the
ve hicle's
Gross Veh icle Weight Rating
("GVWR").
The "GVWR" includes the we ight of the basic
ve hicle, all factory installed accessories, a full
tank of f uel, oil, coo lant and othe r fluids plus
max imum load. The maximum load includes
the number o f passenger s that the ve hicl e is
intended to carry ("se ating capacity") w it h an
assumed weig ht o f 150 lbs (68 kg) for each
passenger at a designated seating position
and the tota l weight of any luggage in the ve
h icle. If you tow a trailer, the weight of the
trailer hitch and the tong ue weight of the
Tire s an d wheel s 243
loaded tra ile r must be included as part of the
vehicle load .
T he
Gro ss Ax le Weight Rating (" GAWR") is
the max imum load th at can be applied at each
of the vehicle's two axles .
T he Gross Vehicle Weight Rat ing and t he
G ross Ax le Weig ht Ra ting are l iste d on the
s af ety comp liance s tic ke r la bel lo cated on the
driver's side 8 -pillar . Yo ur Audi has 5 sea ting
positions,
2 in the front and 3 in the rear fo r
total seating capacity of
5. Eac h seating posi
tion has a safety be lt
c> page 133 , Safety
belts.
The fact that there is an upper limit to yo ur
vehicle's Gross Vehicle We ight Rating means
that the total weig ht of whatever is being car
ried in the vehicle (includ ing the weight of a
tra ile r hitch a nd the tongue weight of the
loaded tra ile r) is lim ited . The more passen
gers in the vehicle or passengers w ho are
heavier than the sta ndard we ights assumed

occupants and l uggage or other cargo that
t h e ve hicl e can carry. For the locat ion of the

.&_ WARNING
-=
Overloading a vehicle can cause loss of ve-
h icle cont ro l, a c rash or other accident, se
rious pe rsonal injury, and even death.
- Ca rrying more we ight tha n your veh icle
was des igned to carry wi ll prevent the
veh icle from handling properly and in
crease the risk of the loss of vehicle con
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
ve hicle w it hi n a safe distance .
- Tires o n a vehicle that has been over load
ed can fail suddenly, including a blowout
a nd sud den defla tion , causing loss of
cont rol and a crash .

continental limits of the United States or Can
ada, there is the possibility that
- unleaded fuels for vehicles with cata lytic
converter may not be available;
- fuel may have a considerably lowe r octane
rating. Improper fuel may cause engine
damage ;
- service may be inadequate due to lack of
proper service facilities, tools or testing
equipment ;
- replacement pa rts may not be readily availa
ble.
- Navigation systems for vehicles built for the
U.S.A. and Canada will not necessar ily work
in Europe, and may not work in other coun
tries outside North America .

Maintenance
General
Your vehicle has been designed to help keep
maintenance requirements to a minimum.
However, a certain amount of regular mainte
nance is still necessary to assure your vehicle's
s afety, economy and rel iability. For detailed
vehicle maintenance consult your Warranty &
Maintenance booklet.
Under difficult operating conditions, for ex
ample at extremely low outside temperatures,
i n very dusty regions , when towing a trailer
very frequently, etc., some service work
should be performed between the intervals
specified. This applies particularly to:
- oil changes, and
- cleaning or replacing the air filter .
(® For the sake of the environment
By regularly maintaining your vehicle, you
help make sure that emission standards
are maintained, thus minimizing adverse
effects on the environment.
Important considerations for you and
your vehicle
