Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
~
Shut t he engine off when you are not driving
the vehicle.
~
Do not warm up the vehicle by letting the en-
gine run at idle .
The idling phase is automat ically reduced for
veh icles with the Start-Stop-System. It is effi-
cient to switch off the engine in vehicles without
the Start-Stop-System when stopped at ra ilroad
crossings and long red lights . Turning the engine
off for just 30-40 seconds saves more fuel than is
burned by sta rt ing the engine ag ain.
It takes a long t ime for the engine to warm up
fu lly when it is runni ng at idle . Howeve r, wear
and noxio us emiss ions a re espe cially high when
the eng ine is wa rm ing up. So you sho uld drive
away as soon as you sta rt t he engi ne and avo id
running at high rpms whi le the engine is still
warming up .
(D Note
Do not leave engine idling unatten d ed after
starting . If warning lights should come on to
indicate im proper operation, they wou ld go
unheeded. Extended idling a lso produces
heat, wh ich could result in overheat ing or
other damage to the vehicle or other proper-
ty.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel.
~
Have your veh icle serviced at regu lar intervals.
By having your veh icle reg ularly serviced by an
Audi dea ler helps to ensure that it runs proper ly
and econom ically. The condition of your veh icle
not on ly affects its safety and ability to ho ld its
value, it a lso affects
fuel consumption .
Check you r oil each time you fill your tank.
The amount of oil used is re lated t o e ngine load
a nd speed.
Driving and the envir o nment
It is normal for the oil consumption of a new e n-
gine to reach its lowest value after a certain mi le-
age has been dr iven.
You m ust dr ive your vehicle abou t 3,0 0 0 m iles
(S,0 00 kilometers) befo re yo u can properly as -
sess oil consumption .
Th is also ap plies t o fue l cons um pt ion and eng ine
output .
CD Note
- Have your vehicle maintained pro perly and
in accordance with t he se rvice recommend a-
tions in your War ra nty
& Main t en a nce book-
let . Lack of proper maintenan ce as we ll as
improper use of the vehicle will impair the
function of the em ission cont rol system and
could lead to damage.
- Do not alte r or remove any component of
the Emission Contro l System unless ap-
proved by the man ufacturer.
- Do not alte r or remove any device, such as
heat shields, switches, ign it ion wires,
valves, which are designed to protect your
vehicle's Emission Contro l System a nd othe r
im portan t vehicle components .
Fewer short trips
Fuel consumption will always be relatively high
on short trips.
~
Try to avoid driv ing short distances with a cold
eng ine .
The engine and cata lytic conve rter have to reach
their opt imal
operating temperature to reduce
fuel consumpt io n and noxious emiss ions effec-
tively.
Just afte r starting, a cold engine in a mid-size car
only achieves a fuel economy of 6-8 m iles per
gallo n (30-40 l/ 100 km) . After about a half a
mile, fuel economy climbs to 12 mpg (20 l/100
km) . Afte r about
2.5 miles (4 km), the eng ine is
at its proper operat ing temperature and fue l
eco nomy has reached a no rma l level. So you can
see th at you should avoid sho rt tr ips wheneve r
poss ible. .,.
