0 Note
Driving with an insufficient oil level is likely to cause severe damage
to the engine.
[ i] Tips
• The oil pressure warning display~ is not an indicator of the oil
level. Do not rely on it. Instead, check the oil level in your engine at
regular intervals, preferably each time you refuel, and always before
going on a long trip.
• If you have the impression your engine consumes excessive
amounts of oil, we recommend that you consult your Audi dealer to
have the cause of your concern properly diagnosed. Keep in mind
that the accurate measurement of oil consumption requires great
care and may take some time . Your Audi dealer has instructions
about how to measure oil consumption accurately. •

The oil level needs to be checked at regular intervals. The best times
to do this are whenever you refuel and prior to long tr ips.
Depending on the way the vehicle is driven and the operating condi­
tions, oil consumption can be up to 1 quart per 1 .200 miles (1 liter
per 2.000 km) . Consumption may be higher within the first 3 .000
miles (5.000 km) .•

models; 60% for Canadian models). This mixture both assures the
necessary frost protection 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 coolant in the summer by
adding plain water.

• Before winter sets in, have the coolant checked to see if the
coo lant additive in your vehicle is sufficient to meet the climate
conditions. This is especia lly important if you live in a region where
the winter is extremely cold . If necessary, increase the proportion of
coolant additive to 60%.
• When adding coolan t additive to your coo ling system,
remember:
-We recommend using only coolant additive
G12+ + (check the
label) for your vehicle. This coolant additive is avai lable at autho­
riz ed Audi dealers. Other types of antifreeze can significantly reduce corrosion protection. The resulting corrosion can cause a
loss of coolant and serious engine damage.
• Do not add any type of radiator leak sealant to your vehicle's
engine coolan t. Adding radiator repair fluid may adversely 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.

- Read the e ngine coo lant level from the coo lant expan -
sion tank~ fig. 242. With a cold engi ne, the coolant level
sho uld be between the "min" and "max" markings. W hen
the engine is warm, the level may be slightly above the
"max" marking .

T o obtain an accurate reading, the engine must be switched off .
The expansion tank in your vehic le is equipped with an e lectric
coolant level sensor.
When the coolant level is too low, the warning light in the Auto ­
Check System ~
page 37 will blink until you add coo lant and the
level has been restored to normal. Even though there is an electric
coolant level sensor, we still recommend you check the coo lant level
from time to time .
Coolant loss
Coolant loss may indicate a leak in the cooling system. In the event
of coolant loss, the cooling system should be inspected immedi­
ately by your authorized Audi dealer . It is not enough merely to add
coo la nt.
In a sealed system, losses can occur only if the boiling point of the
coolant is exceeded as a result of overheating .
0 Note
Do not add any type of radiator leak sealant to your vehicle's engine
coolant . Adding radiator repair fluid may adversely affect the func­
tion and performance of your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty. •
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine compartment,
always read and heed all WARNINGS~ & in "Working in
the engine compartment" on
page 301.
- Turn off the engine.
- Let the engine cool down. Place
a thick rag over the coolant expansion tank
~ page 308, fig. 242 and carefully twist the cap counter­
clockwise ~& .
Add coolant.
- Twist the cap on again
tightly .
Replacement engine coolant must conform to exact specifications
~ page 307, "Coolant". Even in an emergency, if coolant additive
G12++ , G12 + or G12 is not availab le, do not use a different additive .
Use plain water instead until you can get the correct add itive and
can restore the correct ratio. This shou ld be done as soon as
possible.
If you have lost a considerab le amount of coolant, then you should
add cold antifreeze and cold water only when the engine is cold .
A lw ays use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Excess coolant will be
forced out through the pressure relief valve in the cap when the
eng ine becomes hot.
& WARNING
• The cooling system is under pressure and can get very hot.
Reduce the risk of scalding from hot coolant by following these
steps.
-Turn off the engine and allow it to cool down .
- Protect your face , hands and arms from escaping fluid and
steam by covering the cap with a large , thick rag.
- Turn the cap slowly and very carefully in a counter-clockwise
direction while applying light , downward pressure on the top
of the cap.
- To avoid being burned, do not spill antifreeze or coolant on
the exhaust system or hot engine parts. Under certain condi-
tions , the ethylene glycol in engine coolant can catch fire . ...

-Read the brake fluid level from the brake fluid reservoir
~ fig. 243. The brake fluid level must be between the
"MIN" and "MAX" markings.
The brake fluid reservoir is located at the rear partition of the engine
compartment on the left side=> page 302.
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 fluid level falls considerably below the "MIN" mark, the
brake warning/indicator l ight (U.S. models:
BRAKE , Canadian models:
CCD> l will come on=> page 22 and=> page 30. Do not continue to
operate the vehicle . The complete brake syste m shou ld be thor ­
oughly checked by an authorized Audi dealer or other qualified
facility and the cause corrected. If the brake fluid level is too low, the
brake warning/indicator light will illuminate . Contact an authorized
Audi dea ler
immedi ately. •
Changing brake fluid
Have the brake fluid changed by an experienced techni ­
cian.
Brake fluid absorbs moisture from the air. 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 po int of the brake fluid will also
decrease considerably and decrease braking performance.
T herefore, the brake fluid must be changed
ever y two yea rs. Always
use new brake fluid which conforms to Federa l Motor Veh ic le Stan­
dard "FMVSS 116 DO T 4".
The brake fluid reservoir can be difficult to reach, therefore, we recommend that you have the brake fluid changed by your autho­
rized
Audi deal er. Your dealer has the co rrect tools, the right brake
fluid and the know-how to do this for you.

Tires
General notes
Tires may be the least appreciated and most abused parts
of a motor vehicle.
Tires may be the least appreciated and most abused parts of a
motor vehicle. Tires are, however, one of the most important parts
of a vehicle, particularly considering the comparative ly sma ll patch
of rubber on each tire that assures that all- important contact
between you, your vehicle and the road .
Maintaining the correct tire pressure, making sure that your vehicle
and its tires do not have to carry more weight than they can safely
handle, avoiding damage from road hazards and regu lar ly
inspecting tires for damage inc luding cuts , slashes irregular wear
and overa ll condition are the most important things that you can do
to help avoid sudden tire failure including tread separation and
b lowouts .
Avoiding dama ge
If you have to drive over a curb or similar obstacle, drive very slow ly
and as close as possible at a right angle to the curb.
A lways keep chemica ls includ ing grease, oil, gasoline and brake
f luid off the tires.
I nspec t the tires regularly for damage (cuts, cracks or blis ters, etc.l.
Remove any foreign bodies embedded in the treads.
Storing tires
Mark tires when you remove them to indicate the direction of rota ­
tion . This ensu res you to be ab le to mount them correctly when you
reinstal l them. When removed, the wheels or tires shou
ld be stored in a coo l, dry
and preferably dark place.
St ore t ires in a vertical posit ion if they a re not mounted on rims, in
a horizontal position if they are mounted on rims.
New tire s
New tires have to be broken in~&.
The tread dep th of new tires may va ry, according to the type and
make of tire and the tread pattern.
Hidden d ama ge
Damage to tires and rims is often not readily visible. If you notice
unusua l vibration or the vehicle pul ls to one side, this may indicate
that one of the tires has been damaged . The tires must be checked
immed iately by an authorized Audi dealer or qualified workshop .
Unidire ction al tir es
A unidirectio nal tire can be iden tif ied by arrows on the s idewa ll, that
point in the direction the tire is designed to rotate. You must follow
the specified direction of ro tation . This is necessary so that these
tires can deve lop their optimum characteristics regarding grip, road
noise, wear and hydroplaning resistance . For more information
~ page 349.

crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
low speed.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power steering,
power brakes, power windows, power seats, radio, and heater, to
the extent that these items are available as factory-installed equip­
ment (whether installed or not).
Aspect ratio means the ratio of the height to the width of the tire in percent.
Numb ers of 55 or lower indicate a low sidewall for improved
steering response and better overall handling on dry pavement.
Bead
means the part of the tire that is 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.
& WARNING (continued)
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• If you notice unusual vibration or if the vehicle pulls to one side
when driving, always stop as soon as it is safe to do so and check
the wheels and tires for damage . •
Cold tire inflation pressure
means the tire pressure recommended by the vehicle manufacturer
for a tire of a designated size that has not been driven for more than
a couple of miles (kilometers) at low speeds in the three hour period
before the tire pressure is measured or adjusted .
Curb weight means the weight of a motor vehicle with standard equipment
including the maximum capacity of fuel, oil, and coolant, air condi­
tioning and additional weight of optional equipment.
Extra load tire
means a tire designed to operate at higher loads and at higher infla ­
tion pressures than the corresponding standard tire . Extra load tires
my be identified as "XL",
"xi", "EXTRA LOAD", or "RF" on the side ­
wall.
Gross Axle Weight Rating ("GAWR")
means the load-carrying capacity of a single axle system, measured
at the tire -ground interfaces .
Gross Vehicle Weight Rating ("GVWR"l
means the maximum total loaded weight of the vehicle.

& WARNING (continu ed )
• The driver is respon sible for the correct tire pres sures for all
tire s on the vehicle . The applicable pre ssure values are located on
a sticker on the driver 's side B-pillar .
• Only when all tires on the veh icle are filled to the correct pre s­
sure , the tire pressure monitoring system can work correctly .
• The use of incorre ct t ire pressure values can lead to a ccidents
or other damage. Therefore it is essential that the driver observe
the specified tire pressure values for the tires and the correct pre s­
sures for the function of the tire pressure monitor ing system.
• Always inflate tires to the recommended and corre ct tire pres ­
sure before driving off.
• Driving with underinflated tires bend more , letting them get
too hot resulting in tread separation, sudden tire failure and loss
of control.
• Excessive speed and /overloading can cause heat build-up ,
sudden tire failure and loss of control.
• If the tire pre ssure is too low or too high, the tires will wear
prematurely and the vehicle will not handle well .
• If the tire is not flat and you do not have to change a wheel
immed iately , drive at reduced speed to the nearest service stat ion
to check the tire pres sure and add air as required.

Tires and vehicle load limits
There are limits to the amount of load or weight that any vehic le and
any t ir e can carry. A veh icle that is overloaded w il l not handle wel l
and is more difficu lt to stop. Overloading can not only lead to loss
o f veh ic le control, but ca n also damage impor ta nt parts of the
vehic le and can lead to sudden tire failure, inc luding a blowout and
sudde n defla tion that can cause the vehic le to crash .
Your sa fety and that o f your passen gers also depends on mak ing
sure that load limits are not e xceeded. Vehicle load includes every ­
body and everythi ng in and on the veh ic le. T hese load lim its a re
technica lly referred to as the vehicle's
Gross Vehi cle We ight Rating
(" GVWR") .
T he "GVWR" includes the weight of the basic vehic le, all factory
insta lled acces so ries, a ful l ta nk of fuel, oil, coolant an d othe r flui ds
p lus maximum load. The maximum load inc ludes the number o f
p asse ngers that the vehicle is inte nded t o carry ("sea ting capacity")
w ith an assu med we ight o f 150 l bs (68 kg) fo r each passe nger at a
designated seating position and the total weight of any luggage in
t he vehicle. If you tow a trailer, the we ig ht o f the tra iler h itch an d th e
tongue weight of the loaded trailer must be included as part of the
ve hicle l oad.
The
Gross Axle Weight Rating !"GAWR") is t he maximum load that
can be applied a t each of the vehicle's two ax les.
The Gross Veh icle Weig ht Rating and t he G ross Axle Weig ht Rat ing
are listed on the safety comp liance sticker labe l located on the
d river 's s ide B -pi llar . Y o ur Au di h as 5 s eating positi ons, 2 i n the fro nt
and 3 in the rear for total seating capacity of 5 . Each seating position
has a safe ty bel t~
page 205, "Safe ty belts".
The fact that th ere is an upper limit to your vehicle's Gross Vehicle
Weight Rating means that the total weight of whatever is being
carried in the vehic le (includ ing the we ight of a trai ler hitch and the
tong ue weight of the loaded trai ler) is limited. The more passengers
i n the v ehicle or pass engers wh o are heavie r than t he sta nd ard
we ights assumed mean that less weight can be ca rried as luggage . .,_
