A WARNING
-The demands of traffic require your fu ll at­
tention. Always read the chapter
~ page 155, Traffic safety information.
- Obey all traff ic laws when driving.
- The route calculated by the navigation sys- tem is a recommendation for reaching your destination. Obey traffic lights, stopping re­
strictions, one-way streets, lane change re­
strictions, etc.
{Q) Note
- If the dr iving directions conflict with traff ic
laws, obey the traffic laws.
- To reduce the risk of an accident, adjust the
volume of the navigation system so that sig­ nals from outs ide the veh icle, such as police
and fire s irens, can be heard easily at all
t imes.
@ Tips
- Snow and obstruct ions on the GPS antenna
or interference caused by trees and large
buildi ngs can impair satellite reception and
affect the sys tem's ability to dete rmine the
vehicle pos ition. Several deactivated or ma l­
functioning satellites can also inter rupt GPS
reception and affect the system's ability to
determine the vehicle position.
- Because street names sometimes change, the names stored in the MMI may in rare cases differ from the actual street name .

Check ing and F illing
I f you must add oi l between oi l changes, use an
oil that matches the Audi oi l quality standard
listed on the st icker. The sticker is located at the
front of the engine
compartment <=> page 325,

e ngin e oil from Audi G enuin e Part s
Using the proper engine oil is important for the
functionality and service life of the eng ine. Your
engine was factory-filled with a h igh-quality oil
which can usually be used throughout the entire
yea r.
0 Note
Your Limited New Vehicle Warranty does not
cover damage o r malfunctions due to failure
to follow recommended maintenance and use
requirements as set fo rth in the Aud i Owner's
Man ual and Warranty
& Maintenance booklet.
- Use only a high qual ity eng ine oi l th at ex-
p ressly complies with the Audi oil q uality
standard specified for your vehicle's engine .
Using any other oil can cause se rious engine
damage .
- Do not mix any lubricants or other additives into the engine oil. Doing so can cause en­
gine damage.
(D Tips
If you need to add oil and there is none availa ­
ble that meets the Audi oi l quality standard
your engine requi res, you may add a total of
no more than 0.5 qt (0.5 l) of a h igh-quality
"synthet ic" o il that meets the following speci­
fications.
- Vehicles with gasoline eng ine: ACEA A3 or
API SM with a viscosity grade of SAE OW-30,
SAE 5W-30 or SAE 5W-40.
- Vehicles w ith diesel eng ine: ACEA C3 or
API CF with a v iscosity grade of SAE OW-30
or SAE 5W-30 .
- For more information about engine oi l that
has been approved for your vehicle, please
contact eithe r your authorized Aud i dealer
or Audi Custome r Relat ions at

Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all of
its moving ports.
In order to prov ide effect ive lub ricat ion and cool ­
ing of internal engine components, all internal
combustion engines consume a certain amount
of oil. Oil consumption var ies from engine to en­
gine and may change significantly over the life of
the engine. Typically, engines w ith a specified
break-in period
(see<=> page 80) consume more
o il dur ing the break-in per iod than they consume
after o il consumption has stabi lized .
U nder normal cond itions, the rate of oil con­
sumption depends on the quality and viscos ity of
the oil, the RPM (revolutions per m inute) at
wh ich the engine is operated, the amb ient tem­
perature and road condit ions. Furthe r facto rs a re
t h e amo unt of o il di lution from wate r condensa­
t ion or fue l residue a nd the oxidat ion level of the
oi l. As any engine is subject to wear as mileage
builds up, the oi l consumption may increase ove r
ti me until replacement of worn components may
become necessary.
With a ll these variab les coming into p lay, no
standard rate of oil cons umption can be estab ­
li shed or specified . There is no alternative to reg­
ular and frequent checking of the oil level, see
Note .
If the yellow engine oil leve l warning symbo l El
in the instrument cluster lights up, you should
check the o il level as soon as possible
<=> page 32 7. Top off the o il at your earliest con­
venience
<=> page 32 7.
A WARNING
Before you check anyth ing in the e ngine com­
partment, always read and heed all WARN­
I NGS<=> .&. in Working in the engine compart-
ment on page 323.

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.
This applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment.
Sheet metal and bulb holders can have sharp
edges that can cause serious cuts, parts must be
correctly taken apart and then properly put back
together to help prevent breakage of parts and
l ong term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your author ized Audi dealer replace any bulbs for
you, s ince your dealer has the proper tools, the
correct bulbs and the expert ise.
Fuses and bulbs
Gas discharge lamps (Xenon lights) :
Due to the high e lectr ical voltage, have the bulbs
replaced by a qualified technician. Headlights
with Xenon light are identified by the high volt­
age sticker .
LED headlights*
LED headlights require no maintenance. Please
contact your authorized Audi dealer if a bulb
needs to be replaced .
.&, WARNING
Changing Xenon lamps without the necessary
equipment can cause serious personal injury.
- Bulbs are pressurized and can explode when
be ing changed. Potential risk of injury!
- On veh icles equipped with gas discharge
bu lbs (Xenon light) life-threatening injuries
can resu lt from improper handling of the
h ig h-vo ltage portions of such lamps!
- Only your authorized Audi dealer or quali­
fied workshop should change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the
bulb holders that can cause serious cuts. If
you are uncertain about what to do, have the work performed by an authorized Audi
dealer or qualified workshop. Ser ious per­
sonal injury may result from improperly per­
formed work.
(D Tips
- If you st ill prefer to replace the light bulbs
yourself, be aware that the engine compart­ ment is a hazardous area to work
in¢ A in
Working in the engine compartment on
page 323.
- It is best to ask your authorized Audi dealer
whenever you want to change a bulb .
