A WARNING
-Never open the hood when there is steam or
coolant escaping from the engine compart­
ment, because there is a risk that you could
be burned. Wait unt il no steam or coolant is
escaping.
- For safety reasons, the hood m ust always be
closed securely while driv ing. Because of
this, always check the hood after closing it
to make sure it is latched correctly . The
hood is latched if the front corners cannot
be lifted.
- If you no tice that t he hood is not latched
while you are driving, stop immediate ly and
close it, because driving when the hood is
not latched increases the r isk of an accident.

Check ing and F illing
Using the proper engine oil is impo rtant for the
functionality and service life of the engine. Your
engine was facto ry-filled with a h igh-quality oi l
which can usually be used throughout the entire
year.
@) Note
Your Limited New Vehicle War ranty 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 Warran ty
& Maintenance booklet.
- Use only a high quality eng ine oil t hat ex-
p ressly complies with the Audi oil qua lity
standard specified for your vehicle's engine.
Using a ny o ther oil can cause serious engine
d am age.
- D o not mix any lubricants o r other addit ives
i nto the engine oil. Doing so ca n cause en­
g ine damage.
(D Tips
I f you need to add oil and there is none availa­
ble t hat meets the Audi o il quality standard
your eng ine requi res, you m ay ad d a tot al of
no more than 0.5 q t (0.5
l) of a h igh-quali ty
"synthe tic"oil that meets t he following speci ­
fications.
- Applies to: gasoline engine: ACEA A3 or
API SM with a viscosity g rade of SAE 0W-30,
SAE SW -30 or SAE SW-40.
- Applies to: diesel engine: ACEA C3 or API C F
with a viscosity grade of SAE 0W-30 or
SAE SW-30.

or Audi C ustome r Relat ions at
1 (800) 822-2834 or visit our web site at
www.audiusa.com or www .aud icanada .ca.
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all of
its moving parts .
In order to provide effective lubr ication and cool­
ing of internal engine components, a ll inter nal
202
combust ion engines consume a certa in amo unt
of oil. Oil consumption varies from engine to en­
gine and may change signi ficantly over the life of
the engine. Typically, engines w ith a specified
break-in period (see
c:::;, page 66) consume more
o il dur ing the break-in per iod than they consume
af ter o il consumption has stab ilized .
Under normal cond itions, the rate of oil con­
sumption depends on the quality and viscos ity of
the oil, the RPM (revo lutions per m inute) at
wh ich the engine is operated, the amb ient tem­
perature and road condit ions. Furt her facto rs a re
the amo unt of o il di lution from wate r condensa ­
t ion or fue l resid ue an d the oxidation level of the
o il. As any engine is sub je ct to wear as mileage
builds up, the oi l cons umption may increase ove r
time unt il replacement of worn components may
become necessary.
With a ll these va riab les coming into p lay, no
standard rate of oil consumption can be estab ­
li shed or spec ified. The re is no alte rnative to reg­
ul ar and freq uent checking of the oi l level, see
Note .
If the yellow engine oi l level warning symbo l in
the instr ument cluster
El lights up, yo u should
check the o il level as soon as possible
c:::;, page 203. Top off the o il at your ea rliest con­
venience
c:::;, page 203.
A WARNING
Before you check a nyth ing in the e ng ine com­
par tment, always read and heed all WARN­
IN GS
c:::;, .&. in Working in the engin e compart­
ment on page 198.
(D Note
Drivi ng w it h an insuff ic ient oil level is likely to
cause severe damage to the eng ine.
(D Tips
- The oil pressure warn ing d isplay. is not
an indicator of the oil level. Do not rely on
it. Instead, check the oil level in your en­
gine at regular intervals, preferably each
time you refuel, and alway s before going
on a long trip .

dicator
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction .
Fig. 192 Instrument clus ter : indicator ligh t w ith message
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread circumfer­
ence and vib ration characteristics of the individu­
al tires.
If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
RE and a message.
If only one tire is affected, the location of that
tire will be indicated.
The tire pressures must be stored in the Infotain ­
ment system again each time the pressures
change (switching between partial and full load pressure) or after changing or replacing a tire on
your vehicle ¢
page 230 . 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
¢page 220, fig.191 .
Tire tread circumference and v ibration character­
istics can change and cause a tire 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
