observe the following notes about the tempera­
ture ranges.
Cold rang e
If o nly the L EDs 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

(D Note
-Aux iliary head lights and other accessories in
front of the coo ling-a ir intake impa ir the
cooling effect o f the coolant. This increases
the risk of the engine overheating during high outside temperatures and heavy en ­
gine load.
- T he front spoiler a lso helps to distribute
cooling air correctly while driving . If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the eng ine over­
heating w ill increase. See an authorized

Driving
Avoid full acc ele ra tion
You sho uld rare ly travel at the maximum vehicle
speed . High speeds cause a disp roportionately
high increase in fuel consumption, emissions and
traffic noise . Slower driving saves fuel.
Reduce idling time
It pays off to stop the engi ne, for examp le when
at rai lro ad crossings or tr affic 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 resta rt the engine.
It t akes a very long time in idle to wa rm the en­
g ine up to operating tempe ra ture . Wear and
emissions are especially high in the warm-up
p hase . Therefore, yo u should begin driving im ­
mediately after starting the engine. Avoid high
RPMs while do ing th is.
Have ma intenanc e performed r egularly
By having maintenance performed regular ly on
your vehicle, yo u can help to reduce f uel con­
sumpt ion before you even start to dr ive. The
maintenance condition of your vehicle not only
affects traffic safety and long-term value but a l­
so impacts
fuel consumpt ion .
A poorly maintained engine can lead to fuel con­
sumpt ion that is 10% higher than normal.
A lso check the
oil le vel when refueling . The o il
consumption
depends large ly on the engine load
and speed. It is normal for the oil consumpt ion
of a new eng ine to reach its lowest point only af­
ter a certain amount of use. Therefore, the oil
consumption can o nly be properly judged after
approx imately 3,000 m i (S,000 km) have been
d riven.
Avoid short trips
The engine and exhaust cleaning system must
reach the ir opt imal
operating temperature to ef­
fectively red uce consumption and em iss ions.
A co ld engine uses a disproportionately h igh
amount of fuel. The engine reaches operating
temperature and consumpt io n normalizes only
afte r approximately
four kilometers.

(D Note
Do not leave engine idling unattended after
starting. If warning lights sho uld come on to
i ndicate imprope r operation, they would go
unheeded. Extended idling also produces
h eat, which could result in overheating or
other damage to the vehicle o r other proper­
ty.
(D Note
- Have your ve hicle ma intained properly and
in accordance with the service recommenda­
t ions i n your Warranty
& M aintenance book­
let. La ck of prope r mai nte na nce as we ll as
imp roper use o f the ve hicle will impa ir the
func tion of the emission cont ro l sys tem and
cou ld lead to damage.
- Do not alte r or remove any compone nt of
the Emission Contro l System unless ap ­
proved by the man ufacturer.
- Do not alte r or remove any dev ice, such as
heat shields, switches, ig nition w ires,
valves, which are designed to protect your
vehicle's Emission Contro l System and other
important veh icle components.

Facility immediately to have the malfunction cor­
rected. The color of the indicator light depends
on the vehicle speed.
A WARNING
-
Driving at higher speeds without the rear
spoiler deployed can impair handling charac­ teristics, making the vehicle harder to con ­
trol.
- Always make sure that the spoiler is de­
ployed when driving at speeds over 85 mph
(140 km/h). If the rear spoiler warning/indi­
cator light in the instrument cluster comes
on, the rear spoiler may not have deployed.
- Never drive at speeds higher than 85 mph
(140 km/h) if the spoiler is not deployed .
Have the spoiler inspected as soon as possi­
ble by an authorized Audi dealer or qualified
workshop.
- Always obey speed limits and other traffic
laws.
A WARNING t =
Improper operation of the rear spoiler can
cause crushing injuries.
-
- Always make sure that nobody, especially
children, is in the way when the rear spoiler
is deployed or retracted.
(D Note
- Never push on the vehicle on the rear spoil­
er. This could cause damage.
- To prevent damage to the rear spoiler do
not lean or place anything on it.
- Only operate the rear spoiler manually when
the luggage compartment lid is close and
the rear spoiler moving parts are not
blocked. Otherwise, damage could occur.
@ Tips
Clean the rear spoiler compartment every 2 to
3 months. To function correctly, the rear
spoiler must be free of ice , snow and leaves.
Intelligent Technology
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engtne.
When a vehicle with a conventional energy sys­
tem is not driven for a long time, the vehicle bat­
tery is drained by equipment (for example, the
immobilizer). In certain circumstances , there
could may not be enough energy to start the en­
gine.
Your vehicle is equipped with an intelligent ener­
gy management system for distributing electrici­
ty. This significantly improves the starting ability
and increases the vehicle battery life.
The energy management system Is made up of
battery diagnosis, idling current management
and dynamic energy management.
Battery diagnosis
The battery diagnosis determines the vehicle bat ­
tery charge level. The sensors determine the bat­
tery voltage, the battery current, and the battery
temperature. The current charge level and the
performance of the vehicle battery are deter­
mined based on this.
Idling current management
The idling current management decreases the
energy used while parked. With the engine
switched off , it manages the energy distribution
to the different electrical components. Data from
the battery diagnosis is taken into account for
this.
Depending on the vehicle battery charge level,
electrical equipment is switched off one item af­
ter the other to prevent the vehicle battery from draining and to maintain the starting ability.
Dynamic energy management
While driving , dynamic energy management dis­
tributes the appropriate amount of energy to the
electrical equipment.
It controls the battery
charge level so that the amount of energy is not ..,_

Checking and Filling
@ For the sake of the environment
-Engine oil should never enter the sewer sys­
tem or come into contact with the ground
under any circumstances.
- Pay attention to legal requirements when
disposing of empty oil containers.
(D Tips
The engine oil consumption may be up to 0.5 quart/600 miles (0.5 liter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumption may be higher during the
first 3,000 miles (5,000 km). Because of this,
the engine oil level must be checked regular­
ly .
It would be best to check each time you re­
fuel your vehicle and before long drives.
Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­
tion.
Before you check anything in the engine compart­
ment, always read and heed all WARNINGS
q .&.
in Working in the engine compartment on
page 235.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance booklet. This is very important because the
lubricating properties of oil diminish gradually
during normal vehicle use.
Under some circumstances the engine oil should
be changed more frequently . Change oil more of­
ten if you drive mostly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traffic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
look dark after the engine has been running for a
short time. This is normal and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposal, along
with the special tools and necessary expertise re­
quired, we strongly recommend that you have
240
your oil changed by an authorized Audi dealer or
a qualified service station.
If you choose to change your oil yourself , please
note the following important information:
& WARNING
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
-
-To reduce the risk of burns from hot engine
oil, let the engine cool down to the touch.
- When removing the oil drain plug with your
fingers, stay as far away as possible. Always
keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one large enough to hold at
least the total amount of oil in your engine.
- Engine oil is poisonous. Keep it well out of
the reach of children.
- Continuous contact with used engine oil is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water .
(D Note
Never mix oil additives with your engine oil.
These additives can damage your engine and adversely affect your Audi Limited New Vehi­
cle Warranty.
@I 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 .

Wheels and Ti res
General information
.,. Check 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.
.,.Have faulty tires or rims re­
placed immediately.
.,.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 .
.,. Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D N ote
-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
2 4 6
and b raking 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.
