@ For the sa ke of the env ironment
- Engine oi l should never enter the sewer sys­
tem or come into contact with the ground
under any circumstances.
- Pay attention to legal requirements when
disposing of empty oil containers.
The engine oil consumption may be up to 0.5 quart/600 m iles (0.5 liter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumption may be higher during the
first 3,000 miles (5,000 km). Because of this,
the engine oil level must be checked regular­ ly.
It would be best to check each time you re­
fue l your vehicle and before long dr ives.
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,
alw ays r ea d and heed all WARNINGS Q .&.
in Working in the engine compartment on
page 244.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
n ance booklet. This is very important because the
l ubri cat ing propert ies of o il diminish gradually
d ur ing normal vehicle use.
Under some c ircumstances the eng ine o il should
be changed more frequently . Change oil more of­
ten if you d rive mostly short distances, ope rate
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 da rk 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 p roper disposal, along
with the special tools and necessa ry expertise re­
qu ired, we strong ly recommend that you have
Ch eck ing and Filling
your oi l changed by an authorized Audi dealer or
a qualified service station .
If yo u choo se to ch ange yo ur oil your self, please
note the follow ing important info rmation:
A WARNING

-To redu ce the r is k of burns from hot eng ine
oil, let the engine cool down to the touch.
- W hen remov ing the oil d rain plug w ith your
fingers, stay as far away as possib le. Always
keep your forearm parallel to the ground to
he lp 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 oil in yo ur 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

mend occasionally chec king the coo la nt level
manually.
If you must add coolant, use a m ixt ure of wa ter
a nd coo lant add it ive. Mixing the coolant additive
with d istilled water is recommended.
Coolant additive
The coolant additive is made of ant i-freezing and
corros ion protection agents. Only use the fo llow­
ing coolant add it ives. These addit ives may be
m ixed w it h each other.
Coolant additive Specification

The amount of coo lant add itive that needs to be
mixed wit h water depends on the climate where
the vehicle will be operated . If the coolant addi ­
tive percentage is too low, the coolant can free ze
and damage the engine.

and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and being pushed out of the cooling system.
A WARNING
The cooling system is pressurized and can be­
come very hot . To reduce the risk of burns
from hot coolant:
- Do not open the coolant expansion tank cap when the eng ine is hot. This increases the
risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coolant tank cap with a large, thick cloth .
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure on the cap .
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the ex­
haust system or hot engine components .
The ethylene g lycol in engine coolant can
catch fire under certain circumstances.
- 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.
(D 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
cont inue driving. See an authorized Audi deal­
er or authorized Audi Service Facility for assis­
tance.

The windshield washer reservoir{!} contains the
cleaning solution for the windshield and the
headlight washer system*¢
page 246, fig. 189.
The reservoir capacity is found in ¢ page 299.
To reduce the risk of lime scale deposits on the
spray nozzles, use clean water with low amounts
of calcium. Always add window cleaner to the wa­
ter. When the outside temperatures are cold, an
ant i-freezing agent should be added to the water
so that it does not freeze.
(D Note
-The concentration of anti-freezing agent
must be adjusted to the vehicle operating
conditions in the respective cl imate. A con­
centration that is too high can lead to vehi-
cle damage.
- Never add radiator anti-freeze or other addi-
tives to the washer fluid. .,.

tain distance driven, a message appears in the
Infotainment system display each time the ig­
nition is switched on or off . The remaining dis­
tance or time is displayed briefly.
- Inspection or oil change due: if your vehicle
has reached an inspection or oi l change interval
or both intervals at the same time, the mes­
sage

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
