Engine oil

If the engine oil level is too low
If you need to add engine oil, use an oil that is
listed on the sticker. The sticker is located at the
front of the engine compartment > page 234,
fig. 156.
If the recommended engine oil is not available, in
an emergency you may add a maximum of 1
quart (1 liter) of ACEA C3 or API SN engine oil
one time until the next oil change.
For more information on the correct engine oil
for your vehicle, contact an authorized Audi deal-
er or authorized Audi Service Facility. Have the oil
changed by an authorized Audi dealer or author-
ized Service Facility.

Checking and Filling

@ For the sake of the environment
— Before changing the engine oil, make sure
you can dispose of the used engine oil cor-
rectly.
— Engine oil must always be disposed of cor-
rectly. Do not dump it in the yard, in the for-
est, or in open water, river channels, or sew-
ers.
— Have your used engine oil recycled by bring-
ing it to a used oil collection site or contact
a gas station.
Cooling system
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.
The coolant level is monitored using the B indi-
cator light. However, occasionally checking the
coolant level manually is recommended.
Messages
& Turn off engine and check coolant level. See
owner's manual
The coolant level is too low.
Stop driving and switch the engine off. Check the
coolant level > page 239.
— If the coolant level is too low, add coolant
=> page 239. Only continue driving once the in-
dicator light turns off.
Ba Coolant temperature: too high. Please let
engine run while vehicle is stationary
Let the engine run at idle for a few minutes to
cool off, until the indicator light turns off.
— If the indicator light does not turn off, do not
continue driving the vehicle. See an authorized
Audi dealer or authorized Audi Service Facility
for assistance.
| Coolant system: malfunction! Please turn
off engine
Do not continue driving, shut the engine off, and
switch the ignition off.
238
— See an authorized Audi dealer or authorized
Audi Service Facility for assistance.
Coolant additive
The coolant additive is made of anti-freezing and
corrosion protection agents. Only use the follow-
ing coolant additives. These additives may be
mixed with each other.


Coolant additive Specification
Gl12evo TL774L
G12++ TL774G
G13 TL774J

The amount of coolant additive that needs to be
mixed with water depends on the climate where
the vehicle will be operated. If the coolant addi-
tive percentage is too low, the coolant can freeze
and damage the engine.



Coolant Freeze protec-
additive tion
Warm min. 40% min. -13 °F
regions max. 45% (-25°O
Cold min. 50% max. -40 °F
regions max. 55% (-40 °C)

@) Note
— Before winter weather begins, have an au-
thorized Audi dealer or authorized Audi
Service Facility check if the coolant additive
in your vehicle matches the percentage ap-
propriate for the climate. This is especially
important when driving in colder climates.
— If the appropriate coolant additive is not
available in an emergency, do not add any
other additive. You could damage 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 coolant.
— Radiator sealant must not be mixed with
the coolant.
— Due to the risk of engine damage, the cool-
ing system should only be refilled by an au-
thorized Audi dealer or authorized Audi
Service Facility. An authorized Audi dealer or >

al information.
Checking the coolant level
> Park the vehicle on a level surface.
> Switch the ignition off.
> Open the hood > page 232.
The coolant expansion tank for some engines is
located in the water drip tray under a cover. Slide
the
cover that is located below the windshield
wiper on the front passenger's side toward the
windshield and remove the cover.
> Check the coolant level in the coolant expan-
sion tank > page 234, fig. 156 using the outer
markings @) > fig. 158. The coolant level must
be between the markings @) when the engine is
cold. When the engine is warm it can be slight-
ly above the upper marking.
> When you add coolant to the expansion tank,
please refer to > page 238, Cooling system.
Adding coolant
Requirement: there must be a residual amount of
coolant in the expansion tank >@.
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled water is recommended.
> Allow the engine to cool.
> Place a large, thick towel on the coolant expan-
sion tank cap.
> Push the release button @ © fig. 158 on the
cap and carefully turn it to the left until you
feel resistance > /\.
> Push the release button again and remove the
cap completely.
> Add coolant mixed in the correct ratio
=> page 238 up to the MAX marking.
> Make sure that the fluid level remains stable.
Add more coolant if necessary.
> Turn the cap to the right to tighten it until you
feel resistance a second time.
Coolant loss usually indicates that there is a leak.
Immediately 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 leaking, coolant loss can re-
sult from the coolant boiling due overheating
and then being forced out of the cooling system.

ZA\ WARNING
— The engine compartment in any vehicle can
be a dangerous area. Stop the engine and al-
low it to cool before working in the engine
compartment. Always follow the informa-
tion found in > page 231, General informa-
tion.
— Never open the hood if you can see or hear
steam or coolant escaping from the engine
compartment. This increases the risk of
burns. The cooling system is under pressure.
When you no longer see or hear steam or
coolant escaping, you may open the engine
compartment with caution.
— When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
— Coolant additive and coolant can be danger-
ous to your health. For this reason, store the
coolant in the original container and away
from children. There is a risk of poisoning.


() Note
Do not continue driving if the coolant expan-
sion tank is empty. Do not add any coolant,
because air could enter the cooling system
and damage the engine. See an authorized

Wheels

Glossary of tire and loading
terminology
Accessory weight
means the combined weight (in
excess of those standard items
which may be replaced) of auto-
matic transmission, power steer-
ing, power brakes, power win-
dows, power seats, radio, and
heater, to the extent that these
items are available as factory-in-
stalled equipment (whether in-
stalled or not).
Aspect ratio
means the ratio of the height to
the width of the tire in percent.
Numbers of 55 or lower indicate a
low sidewall for improved steer-
ing 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.
248
Cord
means the strands forming the
plies in the tire.
Cold tire inflation pressure
means the tire pressure recom-
mended by the vehicle manufac-
turer for a tire of a designated
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 pres-
sure is measured or adjusted.
Curb weight
means the weight of a motor ve-
hicle with standard equipment in-
cluding 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 in-
flation pressures than the corre-
sponding standard tire. Extra load
tires may be identified as “XL”,
“xl”, “EXTRA LOAD”, or “RF” on
the sidewall.

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
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 Rating
(“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-
258
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
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
luggage.
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.
