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 until no steam or coolant is
escaping.
- If the hood is not latched completely, it
could fly up while you are driving and ob­
struct your vision.
- For safety reasons, the hood must always be
closed securely while driving. 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 notice that the hood is not latched
while you are driving, stop immediately and
close it, because dr iving when the hood is
not latched increases the risk of an accident .

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.
- Fo r more information abou t engine o il t ha t
has been approved for your vehicle, please
contact either your authorized Audi dea ler
or Audi Custome r Relat ions at

www .audiusa.com or www .aud icanada .ca.
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

Check ing and F illing
Cooling system
Coolant
The engine coo ling system is filled with a mixture
of pur ified wate r and coolan t addit ive at the fa c­
t ory . T his coo la nt must not be not changed .
The coolant leve l is monito red throug h the . in­
d icator light
¢ page 12. Howeve r, we do recom­
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

TL 774 J
G12++ TL 774 G
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.

Wheels and Tires
General information
1>-(heck your tires regularly for
damage (punctures , cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­ proach the curb at an angle.
1>-Have faulty tires or rims re­
placed immediately.
1>-Protect your tires from oil,
grease and fuel.
.,. Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
1>-Lay tires flat when storing and
store them in a cool , dry location
with as little exposure to light as possible.
_&. WARNING -
-Never drive faster than the
maximum permitted speed
for your tires . This could cause
the tires to heat up too much.
This increases the risk of an
accident because it can cause
the tire to burst .
-Always adapt your driving to the road and traffic condi-
166
tions. Dr ive carefully and re ­
duce your speed on icy or slip­
pery roads. Even winter tires
can lose traction on black ice .
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months . Low
temperatures significantly de­
crease the elasticity of summ­
er tires, which affects traction
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­
aged by road salt or similar
substances.

A WARNING 1 = -
The traction grade ass igned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor­ nering, hydroplaning or peak tract ion charac­
teristics.
A WARNING
The temperature grade for this t ire is estab­
lished for a t ire that is properly inflated and
no t overloaded. Excess ive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
(!) General notes
Applies to: veh icles with tire pressure monitoring system
-
Each tire, including the spare (if provided),
should be checked monthly when co ld and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placa rd or
tire i nflat ion pressure label. (If your vehicle has
tires of a different s ize tha n the s ize indicated on
the veh icle placard or tire inflation pressure la­
be l, yo u sh ou ld de termine the prope r tire infla­
tion pressure for those tires).
As an added safety feature, your veh icle has been
eq uipped w ith a tire pressu re monito ring sys tem
(TPMS) that ill uminates a low tire p ress ure te ll­
tale when one or more of your tires is significan t­
l y under-inflated. Accordingly, when the low tire
p ressure tellta le illuminates, you should stop and
check yo ur tires as soon as possible, and inflate
them to the proper pressure. Driving on a s ignifi­
cantly under-i nflated tire causes the tire to over­
h eat and can lead to t ire failure . Unde r-inflation
a lso reduces fuel efficiency and t ire t read life,
Wh eel s
and may affect the vehicle 's handling an d stop ­
ping ability.
Please note tha t the TPM S is not a s ubstitute fo r
prope r ti re maintenance, a nd it is the dr iver's re­
spons ibility to maintain co rrect t ire pressure,
even if under-inflatio n has not reached the level
to t rigge r ill umination of the TPMS low t ire pres­
s ur e te lltale .
Yo ur vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not ope rating properly. The TP MS ma l­
funct ion indicator is combined with the low t ire
pressure telltale. When the system detects a
malfu nction, the telltale w ill flash for app roxi­
mately one m inute and t hen rema in continuously
illuminated . Thi s seque nce w ill cont inue upon
s u bsequent vehicle star t-ups as long as the mal­
funct ion exists.
When the malfunction indicator is illum inated,
the system may not be able to detect o r signal
l ow tire p ressure as intended. TPMS malfunct ions
may occur fo r a v arie ty of reaso ns, including the
insta llation o f replacement or al ternate tires or
whee ls on the vehicle that p revent the TPMS
from functioning proper ly . Always check the
TPMS ma lf u nction te lltale after replac ing one or
more tires or wheels on yo ur vehicle to ensure
that the rep lacement or a lt ernate tires and
wheels allow the TPMS to continue to function prope rly.
' If the Tire Pressure Monitoring System
indicator appears
Applies to: vehicles wi th Tire Pressur e Mon ito ring System in·
dicator
The tire pressure indicator in the ins trument
cluster informs you if the tire pressure is too low
or if there is a system malfunction .
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread c ircumfer­
ence and v ibration characterist ics of the ind ividu ­
al tires. If the pressure changes in one o r more
whee ls, this is indicated in the inst rument cl uste r
