2012 AUDI A5 COUPE fuel consumption

216 Driving and environment
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 vehicle by letting the
engine run at idle .
It makes sense to shut off the engine in traffic
jams, when waiting for trains to pass at rail ­
road crossings, or at traff ic lights that have
l ong wa its on red. Turning the engine off for
just 30-40 seconds saves more fue l than is
burned starting the eng ine again .
It takes a long time for the engine to warm up
fully when it is running at idle. However , wear
and noxious emissions 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
heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
... Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
authorized Audi dealer helps to ensure that it runs properly and economically . The condition
of your vehicle not only affects its safety and
ability to hold its value, it also affects
fuel
consumption .
Check your oil each time you fill your tank.
The amount of oi l used is re lated to engine
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.
(D Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet . Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avoid driv ing short distances with a
cold engine .
The engine and cata lytic converter have to
reach their optimal
operating temperature to
reduce fuel consumpt ion and noxious emis­
s ions effectively .
Just after starting, a co ld engine in a mid-size
car only achieves a fuel economy of 6-8 mi les
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy cl imbs to 12 mpg
(20 l/100 km) . After about
2 .5 miles (4 km), ll>

temperatures stay below freezing point for l ong periods.
Detergent add itives in the o il w il l make fresh
oil look dark after the eng ine has been run ­
ning fo r a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
D am ag e or m alfun ction s due to lack of
ma intenanc e
It is essential that you change your oil at the
r ecommended inte rva ls using only engine o il
t hat complies wi th A udi oi l standard
VW 502 00. Yo ur Limited New Vehicle War­
ranty does not cover damage or malfunctions
d ue to fa ilure to fo llow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manua l and Warranty
&
Maintenance book let . Your dea ler will have to
deny warranty coverage u nless you present to
the dea ler p roof in the fo rm of Serv ice or Re­
pa ir Orde rs that all s chedu led maintenance
wa s pe rformed in a t imely manner .
Engine oil consumption
The engine in your vehicle dep ends on an ade­
quate amount of oil to lubricate and cool all
of its moving parts.
In o rder to provide effective l ubrication and
cool ing of i nternal engine components, a ll in­
ternal comb ustion eng ines consume a cert ain
amo unt of o il. Oil cons umption varies from
engine to engine and may change significantly
over the life of the engine. Typ ica lly, engines
with a specified break-in per iod (see
c::;, page 213) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under norma l conditions, the rate of oil con ­
sumpt ion depends on the quality and viscosity
of the oil, the RPM (revo lutions per m inute) at
which the engine is operated, the amb ient
temperature and road condit ions. Furthe r fac­
tors ar e the amount of o il d ilution from wate r
condensation or fuel residue and the ox ida­
tion level of the oi l. As any engine is s ubje ct to
Checkin g and fillin g 241
wear as m ileage builds up, the oil consump ­
tion may increase over time until replacement
of worn components may become necessary.
Wi th a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be es ­
tablished or specified. There is no alternative
to regular and frequent check ing of the o il lev ­
el, see
Note .
If the yellow engine oil leve l warning symbo l
Ill in the instrument cluster lights up, yo u
sho uld check the oil leve l as soon as possib le
c::;, page 242. Top off the oil at your earliest
convenience
c::;, page 242.
A WARNING
Before you check anythi ng i n the engi ne
compartment, always read a nd heed all
WARNINGS
c::;, .&. in Working in th e engine
c ompartment on page 23
7.
(D Note
D riving w ith a n insufficient o il level is like­
ly to cause sever e damage to the engine .
(D Tips
- The oil pressure warning display. is
not an indicator of the oil level. Do not
rely on it . Instead, check the oil level in
your engine at regu lar intervals , pref­
erably each time you refuel, and alway s
before going on a long trip .
-If you have the impression yo ur engi ne
c ons umes ex ce ssive amoun ts of o il, we
recommend that you consul t an a uthor­
ized Aud i dea ler to have the cause of
your concern properly d iagnosed. Keep in
mind that the accurate measu rement of
oil consumption requ ires great care and
may take some t ime. An authorized Aud i
dealer has instructions about how to
measu re oil co nsumption accurately.

reduced speed to the nearest service sta­
t ion to c heck t he tire pressure a nd add
air as required.
Driving without va lve stem caps can cause
damage to the tire va lves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are secure ly
mounted on the valve .
@I For the sake of the environment
Underinflated tires will also increase the
fue l consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any t ire can carry.
A vehicle that is ove rloaded w ill not ha ndle
well and is more difficult to stop. Over load ing
can no t on ly lead to loss of vehi cle contro l,
but can also damage important pa rts of the
ve hicle and can lead to sudden tire failure, in­
cluding a blowout and sudd en deflation that
can cause the veh icle to crash.
Your safety and that of yo ur passenge rs a lso
depends on making s ure that load limits are
not exceeded . Vehicle load includes everybody
and everyth ing in and on the vehicle . These
load limits are techn ically referred to as the
ve hicle's
Gross Veh icle W eight Rat ing
(" GVWR ").
T he "GVWR" incl udes the we ight of the basic
vehicle, all f actory installed accessories, a full
tank of fuel, oil, coolant and other fluids plus maximum load . T he maximum load includes
the number of passengers that the vehicle is in tended to carry ("seating capacity") with a n
assumed weig ht of 150 lbs . (68 kg) for e ach
passenger at a des igna ted seat ing pos ition
and the tota l we ight of any l uggage in the ve ­
h icle. If you tow a trailer, the weight of the
tra iler hitch and the tong ue weight of the
loaded trailer must be included as part of the
ve hicle load . T
he
Gro ss Axle We ight Rating ("GAWR") is
the maximum load that can be applied at each
of the veh icle's two axles .
T he Gross Vehicle Weigh t Rat ing and the
G ross Ax le Weight Rating are listed on the
safety comp liance sticker label located either
on the dr iver's s ide B-pillar or on the ins ide of
the fuel fi ller flap . Audi has
4 seating pos i­
t ions, 2 in the front and 2 in the rear for to tal
seat ing capac ity of 4 . Each seating position
has a seat belt ¢
page 154, Safety belts.
The fact that there is an upper limit to yo ur
vehicle 's Gross Vehicle Weight Rating means
that the total weight of whatever is being car­ ried in the vehicle ( includ ing t he weight of a
t railer hitch and the tongue weight of the
l oaded tra ile r) is lim ited. The more passen­
gers in the vehicle or passengers w ho are
heavier tha n t he standard we ights assumed
mean that less weight can be carried as lug ­
gage.
T he tire pressure label o n your Aud i also lis ts
the max imum combi ned weight of a ll of the
occupants and luggage or other cargo that
t h e vehicle can carry. Fo r the location of the
label ¢

A WARNING
-Overloading a vehicle can cause loss of ve-
h icle contro l, a crash or other accident, se­
rious pe rsonal injury, and even death .
- Carrying more we ight than your veh icle
was des igned to carry will prevent the
veh icle from handling properly and in­
crease the risk of the loss of vehicle con­
trol.
- The b rakes on a vehicle that has been
overloaded may not be abl e to stop the
veh icle w it hi n a safe distance .
- Tires on a vehicle that has been overload­
ed can fail s udden ly, incl uding a blowo ut
a nd sud den defla tion, causing loss of
con trol an d a crash.
- Always make sure that the total load be­
i n g tr anspor ted - incl ud ing t he weight o f
a trailer hitch and the tongue we igh t of a
~

-Always make sure the transm ission se­
lector lever (automatic transmiss ion) is
in "P" (Park position) or Neutral (manual
transmission) and the park brake is firm­
ly appl ied .
® For the sake of the environment
-Changing the eng ine settings w ill ad­
versely affect em ission levels. This is det­
rimental to the environment and increas­
es fuel consumption .
- Always observe env ironmental regula­
tions when d ispos ing of old engine oil,
used brake fluid, dirty engine coolant,
spent batter ies or worn out t ires.
- Undeployed airbag modules and p reten­
s ioners might be classified as Perchlo­
rate Material -special handling may ap ­
ply, see www.dtsc.ca .gov/hazardous­
waste/perch lorate . When the veh icle or
parts of the restraint system including
airbag modules safety belts with preten­
s ioners are scrapped, all applicable laws
and regulations must be observed. Your
authorized Audi dealer is familiar w ith
these requirements and we recommend
that you have your dealer perform this
serv ice for you .
