You can call up the fo llowing information in the
on-board computer:
- Da te
- Dr iv ing time from the short-te rm memory
-Average consumption from the short -term
memory
- Average speed from the short-term memory
- Distance driven from the short-term memory
- Current fuel consumption
- Short-term memory overv iew
- Long-te rm memory overview
The short-term memory collects driv ing inf orma­
tion from the time the ign ition is switched on un­
til it is switched off. If you continue driving with­
i n two hours after switch ing the ignit ion off, the
new values are included when ca lculating the cur­
rent trip information.
Unlike the short-term memory, the long-term
memory is not erased automatically. You can se­
lect the time period for evaluating trip informa ­
tion yourself .
Fuel consumption
The current fu el consumption can be shown us­
in g a bar graph ¢
fig. 8. The average consump­
tion stored in the short-term memory is also dis­
played . If the bar is green, your vehicle is saving
fuel through one of the fo llowing functions :
-Recuperation : electrical energy can be stored in
the vehicle battery when the vehicle is coast ing
or dr iving down hill. The bar will move towa rd
0 .
-Cylinder on demand system*: the engine auto­
matically switches four cylinders (4 .0L TFSI) or
six cylinders (6.3L FSI) off when lower power
output is required and other conditions are
met. This change is not noticeable to the pas­
sengers . The cylinders w ill switch on again
when higher power output is needed .

Driving
Economical and environmentally-friendly
driving
The amount of fue l consumption, the environ ­
mental impact and the wear to the engine,
brak es and tir es d epends mostly on your driving
style. W ith an anticipatory and economic driv ing
style, fuel consumption can be reduced by ap­ proximately 10-15% . The following tips will help
you conserve the environment and your money at the same time .
Anticip atory d riving
A vehicle uses the most fuel when acce lerating.
When you drive with ant ic ipat ion , you do not
need to brake as often and so you accelerate less .
When possible, let your ve hicle coast w ith a
g ear
e ngag ed ,
for example , when you notice that the
next traffic light is red. This produ ces a n eng ine
b raking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumption to zero (f uel shut-off during decelera ­
tion).
Shift effici ently
An effective way to save f uel is to upshift earlie r.
Staying in a gear too long uses fue l unnecessari ­
ly. Press down on the accelerator pedal slowly
and avoid "k ick-down".
Avoid full acceleration
You sho uld rare ly t ravel at the maximum vehicle
speed. High speeds cause a disp roportiona tely
h igh increase in fuel consumption, emissions and
traffic noise . Slower driving saves fuel.
Reduce idling time
The Start-Stop system * helps to reduce the id ling
time automatically . In vehicles witho ut the Start­
S top sys tem* , it is efficient to switch the eng ine
off when stopped at ra ilroad cross ings a nd long
red lights . Stopping t he engine for 30 -40 sec ­
onds already saves more fuel than the amount of
extra fuel needed to restart the eng ine .
It takes a very long time in idle to wa rm the en­
gine up to operating temperature . Wea r and
emissions are especially high in the warm -up
phase. Therefore, yo u should begin driving im-
74
mediate ly after s tarting the engine . Avoid high
RPMs whi le doing this.
Have maintenance performed regularly
By having maintenance pe rformed regu la rly on
you r vehicle, you can help to reduce fuel con ­
s u mption before you even sta rt to drive. The
maintenance condition of your vehicle not on ly
affects traffic safety and long-term value but al ­
so impacts fuel consumption. A poorly main­
ta ined engine can lead to fuel consumption that
i s 10% higher than normal.
Avo id short trip s
The engine and exha ust cleaning system must
reach their optima l operating temperature to ef­
fect ive ly reduce consumpt ion and emissions.
A cold engine uses a d isproportionately high
amount of fue l. The engine reaches operating
temperat ure and cons umption no rmalizes on ly
after approximate ly four kilometers.
Check the tire pre ssure
To save fuel, ma ke sure the tires are always in­
flated to t he corre ct pressure
¢ page 291 . The
fuel consumption can increase by 5% if the pres­
sure is only 0 .5 bar too low. Due to the increased
roll ing resistance, low tire pressures w ill also
lead to greater tire wear and will affect driving
behavior.
D rive with summer tires when possib le because
th is can increase fue l economy by up to 10%.
Eliminate unnecessary we ight
Since eve ry po und of extra weight increases f uel
consump tion, it pays to remove any unnecessa ry
weight .
A roof rac k increases the w ind resis tan ce on the
vehicle and shou ld be removed when it is not
needed . You will save approximately 12% o f you r
fuel when at speeds from 62-75 mph (100-120 km/h) .
Save energy
The eng ine d rives the genera tor , which gene rates
e lectric ity; the fuel consumpt ion also increases
with t he demand for e lec tricity . T he refore, switch ..,_

N .... 0 0 :c ' Using the proper engine oil is important for the
functionality and service 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.
- Vehicles with gasoline eng ine: ACEA A3 o r
API SM with a viscosity grade of SAE OW-30,
SAE SW-30 or SAE SW-40.
- For more information about engine oil that has been approved for your vehicle, please
contact e ither your authorized Audi dea ler
or A udi Customer Relat ions at
1 (800) 822-2834 or visit our web site at
www.audiusa.com or www.aud icanada .ca.
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all of
its moving parts .
In order to provide effective lubr ication and coo l­
ing of internal engine components, all internal
combustion engines consume a certain amount
of oil. Oil consumption varies from engine to en­
g ine and may change significant ly over the life of
Ch eck ing and Filling
the engine. Typ ica lly, engines with a specified
break-in period (see ¢
page 73) consume more
o il during the break -in per iod than they consume
after oil consumption has stabili zed.
Under normal cond itions, the rate of oil con ­
sumption depends on the quality and viscosity of
the oil, the RPM (revo lutions per minute) at
which the engine is operated, the amb ient tem­
perature and road condit ions. Further factors are
the amount of o il dilution from water condensa­
t ion or fuel residue a nd the oxidat ion level of the
o il. As any engine is subject to wear as mileage
builds up, the oil consumption may increase ove r
t ime unt il repla cement of worn components may
become necessary .
With a ll these variab les coming into play, no
sta ndard rate of o il cons umption can be estab­
l is h ed or spec ified. The re is no alternative to reg­
u lar and frequent checking of the oi l level, see
Note .
If the yellow engine o il leve l warning symbo l in
t h e instr ume nt cl uster
II lights up, yo u should
check the o il level as soon as possible
¢ page 2 76 . Top off the o il at your earliest con ­
venience
¢ page 276.
A WARNING
-Before you check anyth ing in the engine com-
partment, always read and heed all WARN­
INGS
¢ .& in Working in the engine compart­
ment on page 271 .
@ Note
Driving with an insufficient oil level is likely to
cause severe damage to the eng ine.
(D Tips
- The oil pressu re warning display. is not
an indicator of the o il le vel. Do not rely on
i t. Instead, check the oil level in you r en­
g ine at regular inter vals, preferabl y each
time you refuel, and alw ays before go ing
on a long trip .
-If you have the impression your engine con­
sumes excessive amou nts of oil, we recom-
mend that you consult your Aud i dea le r to .,,.

Checking and Filling
have the cause of your concern properly di­
agnosed. Keep in mind that the accurate
measurement of oil consumption requires
great care and may take some time. Your
Audi dealer has instructions about how to
measure oil consumption accurately.
Checking the engine oil level
A pp lies to: ve hicles w ith oil leve l indicator
The engine oil level can be checked in the Info­
tainment system
Observe the safety precautions c:::> &. in Working
in the engine compartment on page 2 71.
.. Park your vehicle on a level surface.
.. Shut the engine off when it is warm .
.. Switch only the ignition back on.
.. Wait approximately two minutes.
.. Select: the
ICARI function button > Car systems
control button > Servicing & checks> Oil level.
.. Read the oil level in the display . Add engine oil
if the bar in the oil level indicator is just before
"min"
<=:> page 276.
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 regularly. It
would be best to check each time you refuel your
vehicle and before long drives.
@ Tips
The oil level indicator in the display is only an
informational display. If the oil level is too
low, a minimum oil warning appears in the in­
strument cluster. Add oil and close the hood.
The current oil level is displayed in the Info­
tainment system the next time the ignition is
switched on .

A WARNING
Always adapt the tire pressure
to your driving style and vehicle load.
-Overloading can lead to loss of vehicle control and increase
the risk of an accident. Read and follow the important safe­
ty precautions inc:::> page 295,
Tires and vehicle load limits.
-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­ creases tire wear and has a
Tire pressure table
Please note that the information
contained in the following table
was correct at the time of print­ ing, and the information is sub­
ject to change . If there are differ­
ences between this information
and the tire pressures specified
on the label on the driver's side 8- pillar, always follow the specifica-

braking behavior, which in­
creases the risk of an accident.
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
@ For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption.
(D Tips
Audi recommends using the
tire pressure specified for a normal load c:::>
