Coolant temperature indicator
The coolant temperature display c;, page 8,
fig. 3
CD only functions when the ignition is
sw itched on. To prevent engine damage, p lease
observe the following notes about the tempera­
ture ranges.
Cold range
If on ly the LEDs in the left area of the gauge turn
on, the engine has not reached operating tem­ perature yet. Avoid high engine speeds, full ac­
celerating and heavy engine loads .
Normal range
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on. If
the . indicator light in the Infotain­
ment system display turns on, the coolant tem­
perature is too high

(I;} Note
-Aux iliary head lights and other accessories in
front of the cooling-air intake impair the
cooling effect of the coolant. This increases
the risk of the engine overheating during
high outside temperatures and heavy en ­
gine load.
- The front spoiler also helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over­
heating w ill increase. See an authorized
Audi dealer or author ized Audi Service Fa ­
cility for assistance .
Fuel level
The indicator@ only func tions when the ignition
i s sw itched on. If the fuel level drops below 1.9
gal (7
L), a red LED will light up and the rD indi­
cator light will turn on
c::;, page 15. The LED
blinks red when the fuel level is very low.
The fuel tank capacity of your veh icle is listed in
the
Technical Data section c;, page 288. ..,.

lubricating properties of oil diminish gradually
during normal vehicle use.
Unde r some c ircu mstances the eng ine o il should
be changed more frequently . Change oil mo re of­
ten if you drive most ly short distances, ope rate
the vehicle in dusty areas or under predominant ly
stop-and -go traffic condit ions, or have your vehi­
cle where temperatures remain below free zing
for extended periods.
Detergent additives in the oil will make fresh oil
l ook dark after the engine has been running for a
short time. Th is is normal and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposa l, along
with the special tools and necessary expertise re­
qu ired, we strongly recommend that you have
your oil changed by an authorized
A ud i de ale r or
a qualified service station .
If you c hoo se to change your o il y our self , please
note the following important information:
A WARNING
To reduce the risk of personal injury if you
must change the engine oil in your veh icle
yourself:
- Wear eye protection .
- To reduce the risk of burns from hot engine oil, let the eng ine cool down to the touch.
-
- When removing the o il drain plug with your
fingers, stay as far away as poss ible. A lways
keep your forearm paralle l to the ground to
help prevent hot o il from runn ing down your
arm .
- Drai n the oil into a container designed for
this pu rpose, one large enough to hold at
least the total amount of oil in your e ng ine .
- Engine oil is poisonous . Keep it well out of
the reach of ch ild ren .
- Cont inuous contact w ith used eng ine oi l is
harmful to your sk in. A lways protect your
sk in by washing oil off thoroug hly w ith soap
and water.
@ Note
Never mix oil addit ives with your engine o il.
These additives ca n damage your eng ine and
Ch eck ing and F illing
adverse ly affect yo ur Audi Limited New Vehi­
cle Warranty.
@ For the sake of the environment
- Before chang ing yo ur oil, first make sure
you know where you can proper ly d ispose o f
the used oi l.
- Always dispose of used engine o il properly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine oi l by taking it to a used
engine oi l collection faci lity in you r area, or
contact a service station .
Cooling system
Coolant
The eng ine cooling system is fi lled w it h a m ixtu re
of purified water and coo lant additive at the fac ­
tory . This coolant must not be not c hanged.
T he coo lant level is mo nitored th ro ugh
the . in­
dicator light
<:!) page 12. However, we do recom­
mend occasionally checking the coolant leve l
manua lly.
If you must add coolant, use a mixture of wate r
and coolant additive . Mix ing t he coo lant add it ive
with dis tilled water is recommended.
Coolant additive
T he coolant add itive is made of anti-free zing and
cor rosion protect ion agents. On ly use the follow­
i ng coolant additives . These add itives may be
mixed wi th ea ch o the r.
Coolant additive Specification
G 13 TL 774 J
G12++ TL 774 G
The amount of coolant additive that needs to be
mixed with water depends on the cl imate where
the vehicle w ill be oper ated. If the coo lant add i­
t ive percentage is too low, the coolant can freeze
and damage the eng ine .

@ Note
- Before the start of winter, have an author­ ized Audi dealer or authorized Audi Service
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. Th is is especially important
when driving in co lder climates.
- If the appropriate coolant additive is not
available in an emergency, do not add any
other additive . You cou ld damage the en­
gine.
If t his happens, only use wate r and re­
store the correct mixture ratio with the
specified coolant additive as soon as possi­
ble .
- Only refill with new coo lant.
- Radiato r sealant must not be mixed w ith
the coo lant .

~ 0 > 00 ID
.. Read the coolant level on the coolant expansion
tank
c:::> page 236, fig. 180 . The coolant level
must be between the markings when the en­
gine in cold. When the engine is warm it can be
slightly above the upper mark ing .
Adding coo lant
Requirement : there must be a residual amount of
coolant in the expansion tank
c:::> @ .
.. Let the engine cool down.
.. Place a clot h over the coolant expansion tank
cap and unscrew the cap counterclockwise
c:::> ,A .
.. Add coo lant mixed in the correct rat io
c:::> page 239 up to the upper marking .
.. Make sure that the fluid level remains stable.
Add more coolant if necessary .
.. Close the cap securely .
Coolant loss usually ind icates there is a leak. Im­
mediate ly dr ive your vehicle to a n author ized
Audi dealer or author ized Audi Service Fac il ity
and have the cooling system inspected. If the
cooling system is not lea king , a loss can come
from the coolant boiling through overheat ing
and being pushed ou t of the cooling system .
Lil WARNING
- The cooling system is under pressure. Do
not open the coo lant expansion tank cap
when the engine is hot. This increases the risk of burns.
-The coolant additive 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 switch
on even if the ignition is switched
off, wh ich
increases the r is k of injury.
@ Note
Do not add coolant if the expans ion tank is
empty . A ir could enter the cooling system and

A WARNING
--
- Ser ious personal injury may occur as a result
of improperly performed maintenance, ad­
justments or repairs .
- Always be extremely careful when work ing
on the vehicle . Always follow commonly ac­
cepted safety practices and general com­ mon sense. Never risk pe rsonal inj ury.
- Do not attempt any of the maintenance,
checks or repairs described on the following pages if you are not fu lly famil iar with these
or other proced ures with respect to the ve­
h icle, or are uncerta in how to pro ceed.
- Do not do any work without the proper tools
and eq uipment. Have the necessary wo rk
done by your authorized Audi dealer or an­
other proper ly equipped and qualified work­
shop.
- The engine compartment of any motor vehi ­
cle is a potentially hazardous area . Never
reach into the area around or touch the radi­
ator fan.
It is temperature controlled and
can switch on suddenly
-even when the en­
g ine is off . The radiator fan switches on au­
tomatically when the coolant reaches a cer­
tain tempe rature and will cont inue to run
until the coolant temperature d rops.
- Always sw itch off the ignition before anyone
gets under the vehicle.
- Always support your veh icle with safety
stands if it is necessary to work underneath
the vehicle. The jack suppl ied with the veh i­
cle is no t adequate for this pu rpose and
could collapse caus ing serious personal in­
jury.
- I f you must wor k unde rneath the vehicle
with the wheels on the ground, always make
sure the vehicle is on level ground, that the
wheels are always securely blocked and that
the engine cannot be started.
- Always make sure the transmission se lector
lever (automatic transmiss ion) is in P (Park
position) and the park brake is applied.
