2012 AUDI A8 fuel

-When not in use, to reduce fuel consump­
tion, wind noise and to guard against theft.
A WARNING
- Use of an unapproved roof rack or incor­
rect mounting of an approved roof rack
can cause the roof rack or the items at­
tached to it to fall off the roof onto the
road .
- Objects falling from the roof of a veh icle
can cause a crash and personal injury .
- Only mount the roof rack on the desig­
nated locations on the roof
c::> fig . 70 .
-The roof rack system must be installed
exactly according to the instructions pro­
vided.
- When driving w ith a roof rack system,
changes to the center of gravity and wind
resistance can change the veh icle han­
dling and lead to a collision . Always
adapt your driv ing and your speed to the
current conditions.
0 Not e
-Your vehicle warranty does not cover any
damages to the vehicle caused by using
r oof racks or mount ing structures not
approved by Audi for your vehicle. The
same applies to damage resulting from
incorrect roof rack installation.
- Always check the roof rack mountings
and hardware before each trip and dur­
ing a trip to make sure everything is se­
cure ly tightened . If necessary, retighten
the mount ings and check the ent ire sys­
tem from t ime to t ime.
- After mounting a roof rack system, or
when you transport objects on the roof
of your veh icle, the height of the vehicle
i s naturally increased. Be careful when
driv ing under low br idges or in parking
garages for example. This could cause
damage to the load and even the vehicle
i tself.
- Make sure the open rear lid and the sun­
roof* do not come into contac t with the
roof rack .

Loading the roof rack
Always distribute loads evenly. Make sure
anything on the roof rack is securely tied
down .
.. Always distribute the loads on the roof rack
even ly .
.. Always attach items to the roof rack secure-
ly before you d rive off .
The maximum permissible roof weight is
2 20
lb (100 kg ).
The roof weight is the total of
the weight of the roof rack, the attachments
and the cargo you a re carrying. You must also
not exceed the maximum load we ight for the
roof rack you are using .
When using a roof rack system which has a l ower load ca rrying capaci ty , you must not use
up the tota l maxim um permissible load car ry ­
i ng capacity specified above . Instead, you
sho uld load the roof rack system only to the
maximum capacity specified by the manufac ­
turer of the roof rack system.
A WARNING
---Weak, damaged or improper straps used
to secure items to the roof rack can fail
during hard braking or in a collis ion and
cause ser ious personal injury.
- Make sure the roof rack is installed exact­
ly as specified above
c::> page 68.
-Always use su itable mount ing straps for
securing items to the roof rack to help
p revent items from sh ifting or flying for­
ward.
- Items on the roof rack must always be
securely mounted.
- The use of a roof rack can negat ively af­
fect the way a veh icle hand les . Cargo
that is large, heavy, bulky, long or flat
will have a greater negat ive influence on
the vehicle's aerodynamics, center of gravity and overall handling . Always
drive s lowly, avoid sudden braking and
maneuvers when transporting cargo on
the roof of your vehicle .

70 Seats and storage
-Never exceed the maximum permissible
load carrying capacity of the roof of your
vehicle, the permissible axle weights and
the permissible total weight of your vehi­ cle
c::, page 276, Weights .
@ For the sake of the environment
As a result of the increased wind resist­
ance created by a roof rack, your vehicle is
using fuel unnecessarily. So remove the
roof rack after using it.

Automatic Transmission
tiptronic (8-speed
transmission)
Introduction
Your vehicle is equipped with an electronically
controlled 8-speed automatic transmission .
Upshifting and downsh ifting take place
auto­
matically .
The driver also has the option to shift the
gears
manually r::;, page 112 .
Dynamic Shift Progr am (DSP)
When a moderate driving style is used, the
transmission selects the most economica l
driving mode. The transmission upshifts at a lower RPM and downshifts at a higher RPM to
improve fuel efficiency.
The transmission switches to a sporty mode after a kick-down or when the driver uses a
sporty driv ing style characterized by quick ac­
celerator pedal movements, heavy accelera­
tion, frequent changes in speed and traveling
at the maximum speed.
Selecting the best driving mode is a continu­
ous process. However, the transmiss ion will
also jump to a sporty driving mode if you
press the acce lerator pedal quick ly . When you
do this, the transmission shifts down into a
lower gear, wh ich makes it possible to acceler­
ate quickly (for examp le, when passing anoth­
er vehicle) without having to press the pedal
down into the k ick -down area. Once the trans ­
miss ion has shifted up again, it returns to the
original driving mode as long as it matches
the current driving style.
When driving in hills and mountains, the gear
selection adapts to the grade. This prevents
constant upshifting and downshifting when
driving uph ill.

Driving and
environment
The first 1,000 miles
(1,500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the fir st 600 miles (1,000
kilometers ):
.,. Do not use full throttle.
... Do not drive at engine speeds that are more
than 2/3 of the max imum permitted RPM.
... Avoid hig h engine speeds.
From 600 to 1,000 mile s (1 ,000 to
1,500 kilometers):
... Speeds can gradually be increased to the
max imum pe rm iss ible road or eng ine speed .
During and after break-in per iod
.,. Do not rev the engine up to high speeds
when it is cold. Th is app lies whether the
transm ission is i n N (Neutra l) or in gear.
After the break-in period
... Do not exceed maximum engine speed un­
der any circumstances.
.,. Upshift into the next hig her gear
before
reaching the red area at the end of the tach­
ometer scale
c:> page 10.
During the first few hours of driving, the en­
g ine's interna l friction is higher than later
when all the moving parts have been broken
in . How well this break- in p rocess is do ne de­
pends to a conside rable extent on th e way the
ve hicl e is driven d uring the first 1,0 00 miles
(1, 500 k ilome ters).
0 Note
E xtremely high engi ne speeds are auto­
mat ica lly reduced. However, these rpm
lim its are progr amme d for an engine well
r u n- in, not a new engine .
{® For the sake of the environment
Do not drive with unnecessarily high en­
g ine speeds - upshifting ear ly saves fuel,
reduces no ise and protects the environ­
ment.
, New tires
If your vehicle is runni ng on new tires, drive
part icularly caref ul for the first 350 miles
(500 kilomete rs) afte r fitt ing .
A WARNING
New tires tend to be sl ippery and mus t al­
so be "broken -in" . Be s ure to remember
this dur ing the fi rst 350 mi les ( 500 kilo ­
meters) . Brake gently . Avoid fo llow ing
closely behind other vehicles or other sit­
uations that m ight require sudden, hard
braking .
New brake pads
Remember that new brake pads do not have a
full bra king effect dur ing the fi rst 250 m iles
(400 kilomete rs) afte r they a re insta lled .
New brake pads have to be "burnished in" be­
fo re t hey have optima l grab
c:> A .
During the break- in period, you should avoid
putting severe loads on the brakes. Severe
l oads include, for example, sudden hard brak­
i ng, in particular at very high speeds or, for
example, on mounta in passes .
A WARNING
New b rake pa ds don't have t he bes t stop­
pi ng power and mus t be "broke n-in " dur­
i ng the in iti al 1 00 to 150 mi les (150 to
20 0 k ilometers) of no rma l city driving . You
can compensate for this by pressing the
br ake peda l mo re f irm ly . This also applies
l ater when new pads are installed.

Catalytic converter
It is very important that your emission con­trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
.. Always use lead-free gasoline¢ page 215,
Fuel supply.
.,. Never run the tank down all the way to
empty.
.,. Never put too much motor oil in your en-
gine
¢ page 225, Adding engine oil~-
.,. Never try to push- or tow-start your veh icle.
The catalytic converter is an eff icient "clean­
up" device built into the exhaust system of
the vehicle . The catalytic converter burns
many of the pollutants in the exhaust gas be ­
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critically
importa nt for the life of the cata lytic convert­
e r and proper functioning of the engine.
A WARNING
-
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust pipes, catalytic con­
verter or heat shields. During driving, the
substance used for undercoating cou ld
overheat and cause a fire.
0 Note
- Be aware that just one tank filling with
leaded fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil level
¢ page 225.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis­
fire . U nburned fuel could a lso get i nto
Dri vin g and en vironm ent 195
the exhaust system and this cou ld cause
the catalytic converter to overheat .
- Do not switch off the ignit ion while the
vehicle is mov ing.
- Do not continue to ope rate your veh icle
unde r these conditions, as othe rwise fuel
can reach the catalytic converter. This
co uld result in overheating of the con­
verter, requir ing its replacement .
- To assure efficient operation of the Emis ­
sion Control System:
- H ave your vehicle maintained prope rly
and in accordance w ith the se rv ice rec­
ommendat ions in you r Warranty &
M aintenance boo klet.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle w il l impair
the function of the em ission contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control System is
operat ing properly, the exha ust gas can
have a sul fur -li ke exhaust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or filling the tank with lead-free super
grade gasoline .
Avoid damaging the
vehicle
When you are drivi ng on poo r roads, or over
c ur bs, s teep ramps, etc., ma ke certai n that
low -lying parts s uch as spoilers and exhaust
system pa rts do not bottom o ut and get dam­
aged.
T h is is espec ially true for veh icles w ith low­
s lung chassis (spor ts chassis)* and fully load­
ed vehicles. •

196 Driving and en vironm ent
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than wa lking speed.
A WARNING
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
sto re the full braking effect.
@) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Check the depth of the water before dr iv­
i ng through it.
- 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 vehi­
cle to drive through safely.
- Avoid dr iving through salt water because
i t can cause corrosion.
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels.
Fuel economy, environmenta l impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving style
- operating conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt ion by 10-15 percent . This sec­
t ion will give you some tips on how you can
help the env ironment and your pocketbook.
@ Tips
The consumption estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehi­
cle load and speed, road and weather con ­
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.,. Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are ac­
ce lerating. If you anticipate what is going to
happen next, you will need to brake less and,
thus, acce lerate less . Let the vehicle coast
whenever possible - for example when you see
that the next traffic light is red.

Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
"" Try and keep well below your car's maxi-
mum speed.
Accelerating gently reduces fuel consump­ tion, engine wear, and does not disturb the
environment.
F ue l consumption, exhaust emissions and en ­
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will be reduced by one half. Never drive faster
than the posted speed limit and weather con­
d itions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
"" Shut the engine off when you are not driv­
ing the vehicle.
"" Do not warm up the veh icle by letting the
engine run at idle .
It makes sense to shut
off the engine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings, or at traffic lights that have
l ong wa its on red. Turning the engine
off fo r
just
30-40 seconds saves more fue l than is
bu rned starting the eng ine again .
It takes a long time for the engine to warm up
fu lly when it is running at idle. However, wear
and nox ious em issions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over-
Dri vin g and en vironm ent 197
'
heating o r othe r damage to the veh icle or
other p roperty .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
"" Have your veh icle serviced at reg ular i nter-
vals.
By having your veh icle regu la rly serviced by an
Audi dealer he lps to ensu re that it runs prop­
erly and economically. The condition of your
vehicle not only affects its sa fety and ability to
hold its value, it a lso affects
fuel con sump­
tion .
Check your oil e ach t ime you fill your tank .
The amount of o il used is re lated to eng ine
load and speed .
It is normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has been driven .
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(U) Note
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Ma in­
tenance booklet . Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
em iss io n cont ro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control Sys tem unless ap­
proved by the manufacture r.
- Do not alter or remove any device, such
as heat shie lds, swit ches, ign it ion w ires,
valves, which are designed to p rotec t
your vehicle's Emission Control System
and other important vehicle compo­
nents .

198 Driving and environment
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avo id driving short distances with a
cold eng ine.
The engine and catalyt ic converter have to
reach their optimal
operating temperature to
reduce fuel consumption and noxious emis­
sions effect ively .
Just after starting, a cold engine in a mid-size
car only achieves a f uel economy of 6-8 miles
per gallon (30-40 l/100 km). After about a
half a m ile, fuel economy climbs to 12 mpg
(20 l/100 km). After about
2.5 miles (4 km),
the engine is at its proper operat ing tempera­
ture and fue l economy has reached a normal
l eve l. So you can see that you sho uld avoid
short trips wheneve r possible.
The
outside temperature is also critical in this
r egard. Your car consumes more fuel in the
winter than in the summer.
