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

too high ~page 12.
CD Note
-Auxi lia ry headlights and other ac cessories in

Switching the ignit ion on/off
""To switch the ignition on/off, press the
I START ENGINE STOPI button. Do not press the
brake pedal while doing this.
Starting the engine
"" Press the brake pedal and move the selector
lever
into the P or N position~.&_.
... Press the I START ENGINE STOPI button
~fig. 60. The engine will start.
If the engine should not start immediately, the
starting process is automatically stopped after a
short time. Repeat
the starting process.
.&. WARNING
-I
-Never allow the engine to run in confined
spaces -danger
of asp hyxia tion.
- Never
turn off the engine before the vehicle
has come to a complete stop.
- The brake booster and power steering only
work when
the engine is running. If the en­
gine
is off, you have to use more force when
steering
or braking. Because you cannot
steer and brake
as you usually would, this
could lead to crashes and serious injuries.
CD Note
Avoid high engine speed, full throttle, and
heavy engine load
as long as the engine has
not reached operating temperature yet. You
could damage the engine.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This re­
duces unnecessary emission
s.
Tips
-Some noise after starting the engine is nor­
mal and is no cause for concern.
-
If you leave the vehicle with the ignition
switched on,
the ignition will switch off af­
ter a certain amount of time. Make sure that
electrical equipment such as the exterior
lights are switched off.
Driving
Stopping the engine
... Bring the vehicle to a full stop.
""Move the selector lever into the P position.
... Press the I START ENGINE STOPI button
~page 58, fig. 60.
Emergency off
If it is necessary in unusual circumstances, the
eng i
ne can be switched off while the vehicle is
moving. Briefly press the I START ENGINE STOPI
button twice in a row or press and hold for longer
than
two seconds.
.&. WARNING
!-='
- Never turn off the eng ine before the vehicle
has come to a complete stop.
-
Please note that the brake booster and pow­
er steering
only work when the engine is
r unn ing. When
the engine off, you must use
more force
to steer or brake the vehicle. Be­
cause the usual steering and braking capa­
bility is not available, the risk of accidents or
injuries increases.
- For safety reasons, always park
the vehicle
with the selector lever in the P position.
Otherwise, there
is the risk that the vehicle
could roll.
-
After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes -even with the ignition switched
off. It can also switch on again after some
time if the coolant temperature rises as the
result of heat buildup or ifthe eng ine com­
partment is heated by the sun's rays and the
engine is hot.
CD Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off -there is a risk of damaging the
engine. For this reason, let the engine run for
at idle for approximately two minutes before
shutting it off.

@ For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exhaust gas can have a
sulfur-like
exhaust gas smell under some op­
erating states. This depends on the sulfur
content of the fuel being used. Using a differ­
ent brand of fuel may help, or filling the tank
with lead-free super grade gasoline.

circumstances. This increases the risk of
burns.
-
If tests need to be performed with the en­
gine running, there is additional danger due
to moving components (such as the ribbed
belt, alternator and radiator fan) and from
the high voltage ignition system.
-Do not under any circumstances give gas in­
advertently (for example, by hand from the
engine compartment) if the vehicle is sta­
tionary but the engine is running and a gear
is engaged. Otherwise the veh icle will start
to move immediately and could result in a
crash.

-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.

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 .

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.
