on. T o prevent engine damage, please
observe the following notes about the tempera­
ture ranges.
Cold range
If o nly 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 under normal driving conditions . The
LEDs farther to the right may turn on if the en­
gine is under heavy load or the outside tempera­
ture is high. This is no cause for concern as long

as the. indicator light in the Infotainment dis­
play does not turn on. If the red LED in the rig ht
s ide of the display and the. indicator light in
the d isplay turn on, the coolant temperature is
too high ~page 12.
CD Note
-Auxi lia ry headlights and other ac cessories in
front of the cooling-air intake impair th e
cooling
effect o f the coolant. T his increases
the risk of the engine overheating during
high
outside temperatures and heavy en­
gine load.
- T
he 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 will increase . See an authorized
Audi dealer or authorized Audi Service Fa­
c ility
for assist ance.
Fuel level

tom LED blinks red when the fuel level is very
low.
The
fuel tank capacity of your vehicle is listed in
the Technical Data section¢ page 299.
0 Note
Never drive until the tank is completely emp­
ty.
The irregular suppl y of fuel that results
from that can cause engine misfi res. Uncom­
busted fuel will then enter the exhaust sys­
tem. Th is can cause overheating and damage
to the catalytic converter.
Indicator Lights
Description
The indicator lights in the instrument cluster
blink or turn on. They indicate functions or mal­
functions.
Wit h some ind icator lights, messages may ap­
pear and warning signals may sound. The indica ­
tor lights and messages in the display can be cov­
ered by other displays. To show them again, se­
lect the tab for the indicator lights and messages
using the multifunction steering wheel
¢page 19. If there are several malfunctions,
you can display them one at a time using the
thumbwheel.
Some indicators lights in the display can turn on
in several colors.
Overview
Some indicator lights turn on briefly as a function
check when you switch the ignition on. These sys­
tems are marked with a./ in the following tables.

o System indicator light (MIL)
The system indicator light (MIL) is part of the On
Board Diagnostic system (OBD II). The ¢.j sym­
bol turns on when the ignition is switched on and
turns
off again once the engine is started and
running
at a steady idle speed. This indicates that
the MIL is functioning correctly.
The indicator

-Determine the depth before driving through
water.
-Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water.
- Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
- Avoid driving
through salt water (corrosion).
Economical and environmentally-friendly
driving
The amount of fuel consumption, the envi ron­
mental impact and the wear to the engine,
b rakes and tires depends mostly on yo ur driving
style. Wit h
an anticipatory and economic driv ing
style, fu
el consumption can be reduced by ap­
proximately 10-lSo/o. The following tips will help
you conserve the environment and your money at
the same time.
Anticip atory driv ing
A veh icle uses the most fuel when a ccele rating.
When you drive with anticipation, you do not
need to brake as often and thus acce lerate less.
When possible, let your vehicle coast with a gea r
engaged -for example, when you notice that the
next traffic light is red.
Avoid full acceleration
You should rarely travel at the maximum vehicle
speed. High speeds cause a disproportionately
high increase in fuel consumption, emissions and
traffic noise. Slower driving saves fuel.
Reduce idling time
It pays off to stop the engine, for example when
at railroad crossings or traffic lights with longer
red lights. Stopping the engine for 30-40 sec­
onds already saves more fuel than the amount of
extra fuel needed to restart the engine.
It takes a very long time in idle to warm the en­
gine up to operating temperature. Wear and
emissions are especially high in the warm-up
Driving
phase. Therefore, you should begin driving im­
mediately after starting the engine. Avoid high
RPMs while doing this.
Service regularly
By servic ing you r vehicle regularly, you can help
to reduce fuel consumption before you even start
to drive . The maintenance condition of your vehi­
cle not only affects traffic safety and long-term
val ue b ut also impacts fuel co nsumptio n.
A poorly serviced engine can lead to fuel con­
sumption that is 10% higher than normal.
Also check the oil level when refueling. The oil
con sumpti on
depends largely on the engine load
and speed. It is no rmal for the oil consumption
of a new engine to reach its lowest point only af­
ter a certain amount of use. Therefore, the oil
consumption can only be properly judged after
approximately 3,000 mi (5,000 km) have been
driven.
Avoi d short trip s
The engine and exhaust cleaning system must
reach their optimal operating tempera tu re to ef­
fectively reduce consumption and emissions.
A cold engine consumes a disproportionately
high
amount of f u el. The engine is at operating
temperature and consumption has normalized
only after approximately four kilometers.
Q) Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other proper­
ty.
CD Note
-Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty & M ain tenance book-
let. Lac k of proper mai ntenance as well as
improper use of th e vehi cle w il l impair the
function of the emission control system and
cou ld lead to damage. .,..

@) For the sake of the environment
-Before changing your oil, first make sure
you know where you can properly dispose of
the used oil.
- Always
dispose of used engine oil properly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle
used engine oil by taking it to a used
engine oil collection facility in your area, or
contact a service station.
Coo Ling system
Coolant
The engine coolant performs two functions: it
keeps
the engine from overheating and it pro­
tects the engine from freezing in the winter.
The cooling system is sealed and generally re­
q uires
little attention.
The cooling
system has been filled at the factory
with a
permanent coolant which does not need to
be changed. The coolant consists of a mixture of
specially conditioned water and the manufactur­
er's glycol-based coolant additive G13 antifreeze
with anticorrosion additives (50% for USA mod­
els; 60% for Canadian models). This mixture
both assures the necessary frost protection and
protects metal components in the engine's cool­
ing
system from corrosion and scaling. It also
raises
the boiling point of the coolant.
Do not reduce the concentrat ion of the coolant in
the summer by addi ng p la in water. The propor­
tion of coolant additive must be at least 50°/o
but not more than 60°/o to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
gine cooling system.
For year-round driving,
antifreeze is added at the
factory for temperatures down to:
- -
31 °F ( -35 °C) USA
- -40 °F ( -40 °C) Canada.
242
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled
water is recommended.
A WARNING
~ h . Before you check anything in t e engine com-
partment, always read and heed all WARN­
INGS C)page 236.
CD Note
-Before winter sets in, have the coo lant
checked to see if the coolant additive in you r
vehicle is
sufficient to meet the climate con­
d itions. This is especia l
ly important if you
live
in a regio n where the winter is extre m e­
ly cold . If necessary, increase the proportion
o f coo la
nt ad ditive to 60o/o.
-When add ing coolant additive to your cool­
ing
system, remember:
-We recommend using only coolant addi­
tive G12++
or G13 (check the label) for
your vehicle. This coolant additive is avail­
able at authorized Audi dealers. Other
types of antifreeze can significantly re­
duce corrosion protection. The resulting
corrosion can cause a loss of coolant and
serious engine damage.
-Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding ra­
dia to r repair fluid may adversely
affect the
func tion and performance of your cooling
system and could result in damage not cov ­
ered by your New Veh icle Limited W arranty .

Read and follow the WARNINGS before check­
ing anything
in the engine compartment
Qpage236.
Checking the engine coolant level
""Park your vehicle on a level surface.
"" switch the ignition off.
.. Read the coolant level on the coolant expansion
tank
Q page 238, fig. 184. 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 marking.
Adding coolant
Requirement: there must be a res idual amount of
coo l
ant in the expans io n tank c:?(i) .
""Let the engine cool down.
.. Place a cloth over the coolant expansion tank
cap and unscrew
the cap counterclockwise
c:?,8..
""Add coolant mixed in the correct ratio
i:?page 242 up to the upper marking.
""Make sure that the fluid level remains stable.
Add more coolant if necessary.
"" Close the cap securely .
A coolant loss suggests a leak. Immediately drive
your vehicle
to an authorized Audi dealer or au­
thorized
Audi Service Facility and have the cool­
ing system inspected.
If the cooling system is not
leaking, a loss can come from
the coolant boiling
through overheating and being pushed
out of the
cooling system.
.&. WARNING
-The cooling system is pressurized and can be-
come very hot.
To reduce the risk of burns
from hot coolant:
-
Do not open the coolant expansion tank cap
w ith
the engine hot. There is a risk of burns .
- Stop
the engine and allow it to cool.
-
Protect your face, hands and arms from es-
caping coolant and
steam by covering the
coolant tank cap with a large, thick cloth.
- Turn
the coolant tank cap counterclockwise
slowly and keep light pressure on
the cap.
-
To reduce the risk of burns, do not allow any
antifreeze or coolant to dr
ip onto the ex-
Checking and Filling
ha ust system or hot engine components.
The ethylene glycol in engine coolant can
catch fire under certain circumstances.
- The coolant additive and the coolant can be
dangerous to your health.
For this reason,
keep
the coolant in the original container
away from children. There is a
risk of poi­
soning.
-When working in the engine compartment,
remember
that the radiator fan can switch
on even if
the ignition is switched off, which
increases
the risk of personal injury.
CD Note
Do not add coolant if the expans ion tank is
empty . Air could enter the cooling system and
damage
the eng ine. If this is the case, do not
continu e driving. See an authorized
Audi dea l­
er or authorized
Audi Service Facility for assis­
tance.
Radiator fan
The radiator fan switches on automatically by it­
self.
An auxiliary electric radiator fan switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch
the engine off, the auxiliary fan
can continue running for
up to 10 minutes -even
with
the ignit ion off. It can even switch on again
later by itself c:? & . if
- the temperature of
the engine coolant rises due
to
the heat build-up from the engine in the en­
gine compartment, or
-
the engi ne compartment heats up because the
vehicle is parked in intense sunlight.
.&. WARNING
-To reduce the risk of personal injury never
touch
the radiator fan.
- The auxiliary electric fan
is temperature
controlled and can switch on suddenly even
when
the engine is not running.
