Using the prope r engine oil is important for the
functionality and s ervice life of the engine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
year .
Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's Manual and Warranty & Maintenance booklet .
- Use only a high quality engine oil that ex-
pressly complies with the Aud i oil quality
standard specified for your vehicle's engine.
Using any o ther oil can cause serious engine
damage.
- Do not mix any lubricants o r other additives
into the engine oil. Doing so can cause en­
gine damage.
@ Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
your eng ine requ ires, you may add a total of
no more than 0 .5 quart/li ter of a h igh-quality
"synthet ic"oil that meets the following speci ­
fications.
- ACEA A3 or API SM with a v iscosity grade o f
SAE OW-30, SAE SW -30 or SAE SW-40.

Engine oil consumption
T he engine in your vehicle depends on an ade­
qua te amoun t of oil to lubricate and cool all of
i t s moving par ts.
In order to provide effective lub rication and coo l­
ing of in te rnal engine components, a ll internal
combustion engines consume a cer tain amount
of oil. Oil consumption varies from engine to en ­
g ine and may change sign ificantly over the life of
the eng ine . Typically, eng ines with a spec ified
Ch eck ing and Filling
break-in period (see ¢ page 57) consume more
oi l during th e break-in period than they consume
after oil consumption has stabilized.
Under normal cond itions, the rate of oil con­
sumption depends on the q uality and viscos ity o f
the oil , the RPM (revolutions per minut e) at
which the engine is operated, the amb ient tem­
perature and road condit ions. Further factors are
the amount of oil dilution from w ater condensa­
tion or fuel resid ue and the oxidation level of the
o il. As any engine is subject to wear as mileage
builds up, the oi l consumption may increase ove r
t ime unt il repla cement of worn components may
become necessary.
With al l these variables coming into play, no
standard rate of o il consumption can be estab­
l ished or spec ified . T he re is no alte rnative to reg­
u la r and fre quent chec king of the o il level , see
Note .
If the yellow engine oil level warning symbo l II
in the instrument cluster lights up , you sho uld
check the o il level as soon as possible
¢ page 160. Top off the o il at your earliest con­
venience.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN ­
INGS¢ .&.
in Working in the engine compart­
ment on page 155.
(D Note
D riving wit h an insufficient oil level is likely to
cause severe damage to the engine .
(D Tips
- The oil pressure warn ing display. i s not
an indicato r of the o il le vel. Do not rely on
it . Instead, check the oil level in your en ­
gine at regular intervals , pre fe rabl y each
time you refuel, and alw ays befo re go ing
on a long trip .
-If you have the impression your engine con­
sumes excessive amounts of oi l, we recom­
mend that you consult an author ized Audi
dea ler to have the cause of your concern

The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switch ing between partial and full load
pressure) or after changing or replacing a tire on
your vehicle
c:::> page 184. The tire pressure moni­
toring system only monitors the tire pressure you have stored . Refer to the tire pressure label for
the recommended tire pressure for your vehicle
c:::> page 176, fig. 147.
Tire tread circumference and vibration character­ istics can change and cause a t ire pressure warn­
ing if:
- the tire pressure in one or more tires is too low
- the tire has structural damage
- the tire was replaced or the tire pressure was
changed and it was not stored

-Under certain conditions (such as a sporty
driving style, w inter conditions or unpaved
roads), the tire pressure monitoring system
ind icator may be delayed .
- Do not use run-flat tires on your vehicle. Us­
ing them when not permitted can lead to
veh icle damage or accidents.
(D Tips
- The tire pressure monitor ing system can al­
so stop working when there is an ESC mal­
function.
- Using snow chains may result in a system
malfunction.
- The tire pressure monitor ing system in your

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you .
It is becoming increasingly more and more diffi­
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­
moved before you are able to get to the bulb .
T his applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment .
Sheet metal and bu lb holders can have sharp
edges that can cause serious cuts, pa rts must be
correctly taken apart and then properly put back
together to help prevent breakage o f parts and
long term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your authorized Aud i dea ler rep lace any bulbs fo r
you, since your dealer has the proper tools, the
correct bulbs and the expertise.
Gas di schar ge la mps (Xe no n ligh ts):
Due to the high electr ical voltage, have the bulbs
rep laced by a qualified technician. Headlights
with Xenon light are identified by the hig h volt­
age st icker.
LED headlights* require no maintenance . Please
contact your authorized Audi dea ler if a bulb
needs to be replaced.
_&. WARNING
Changing Xenon lamps wi thout the necessary
equipment can cause serious personal injury .
- Bulbs are pressu rized and can explode when
be ing changed. Potent ial ris k of injury!
- On veh icles equipped with gas disc harge
bu lbs (Xenon light) life-threatening injuries
can resu lt from improper handling of the
high-vo ltage portions of such lamps!
- Only your authorized A udi dealer or quali­
f ied workshop sho uld change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the
201
