156 Intelligent technology
If starting capability is jeopa rdized due to en­
ergy consumption, a message appears in the
driver information disp lay.
You have to start the engine to charge the
battery.
With the engine running
A lthough electrical energy is generated when
the vehicle is being driven, the battery can be­
come discharged. This happens most ly when
little energy is being generated and a great
deal consumed and the battery's state o f
charge is not optima l.
To bring the energy balance back into equili­
brium, consumers which require especially
l arge amounts of energy are temporarily cut
back or switched off. Heating systems in par­
ticular require a great dea l of energy. If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporar ily cut back or switched
off. These systems will be ava ilable again as
soon as the energy balance has been restored.
You will also notice that engine idle speed has been increased slightly . This is normal and not
a cause for concern . By increas ing engine idle
speed the add itiona l energy required is gener­
ated and the battery is charged.
Driver notification in the instrument
cluster display
If battery power drops into the range where it
can limit the ability of the engine to start, th is
is shown in the instrument cluster display
with the following driver message:
(•) Low battery charge : battery will be
charged while driving
This notification reminds you that the starting
capability of the engine may be limited. As
soon as you start driving again, the battery
will be recharged and the notification will go
out.
Driver notification appears and goes out
again
If this driver notification appears after the ig­
nition is turned on or whi le driving and it goes
out again after a while, the battery has been
adequately recharged.
Driver notification appears and does not
go out again
If this driver notif ication appears after the ig­
nition is turned on or while driving and does
not go out again, the battery 's state of charge
is not in the optimal range. Starting ability is
restricted . Have the battery checked as soon
as possible by an autho rized Aud i dea le r o r
qualified wo rkshop.

160 Driving and en vi ro nment
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
.,. Shut the engine off when you are not dr iving
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 ra il­
road crossings, or at traff ic l ights that have
l ong wa its on red . Turning the engine
off fo r
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
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 whi le the engine
is sti ll warming up.
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate imp roper 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 serv iced at regular inter-
vals.
By having your vehicle regularly serviced by an
Audi dea ler helps to ensure that it runs prop­
erly and economica lly. The cond it ion of yo ur
vehicle not only affects its safety and ability to
hold its value, it also affects fuel consump­
tion .
Check you r oil ea ch time you fill you r tank. T
he amount o f oi l used is re lated to engine
load and speed.
It i s normal fo r the oil consump tion of a new
engine to reach its lowest value after a certa in
mileage has been d riven.
You must drive your veh icle about 3,000 m iles
(S,000 kilometres) before yo u can properly
assess oil consumpt ion.
T his also app lies to fue l consumption and en­
gine o utput.
(D Note
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
& Main­
t enance boo klet . Lack of p roper ma inte­
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 sh ie lds, switches, ign it ion w ires,
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 w ith a
cold engine .
T he engine and cata lytic converter have to
reach their opt imal operat ing temperature to
reduce fuel consumption and nox ious emis­
s ions effectively .
- Ju st after starting, a cold engine in a mid­
size car burns the fue l at a poor rate of 6-8
m iles per gallon (30-40 l/l00km). Half a
m ile down the road , the mileage improves
to 12 MPG (20 l/100 km). It w ill take the

172 Cleaning and protection
• Once the stain is no longer visib le, use a soft
dry cloth or tissu e to soak up the moisture .
Do not use leather cleaning produc ts on Al ­
cantara .
You may use a suitable shampoo fo r remov ing
dust and dirt.
Dust and grit in the pores and seams can
scratch and damage the surface . If the car is
l eft stand ing i n the sun fo r long pe riods, the
A lcantara should be p rotected against direc t
sun light to preven t it from f ad ing. Slig ht color
va ria tions will develop in normal use an d are
not an indication of material deterioration .
CI) Note
-Never use chemi cal solven ts (e.g. lighter
fl uid , turpentine), waxes, shoe po lish or
s imilar products on Alcantara ® sur faces.
- To avoid damage, have stubborn stains
r emoved by a commerc ia l cleaning spe ­
cia list.
- Do no t use br ushes, st iff sponges or sim­
ilarly abrasive cleaning a ids.
Safety belts
Only well-maintained safety belts work relia ­
bly when ne eded .
Heavily soiled safety belts may not retr act
p rope rly.
• Keep be lts clean.
• For cleaning, use a m ild soap and wate r sol­
u tio n. Le t be lts d ry thoro ughly and away
from direct s unli gh t.
• Do no t all ow ine rtia reel safety be lts to re­
t ract before they are completely d ry .
• Check the condition of your safety belts
reg­
ularly.
A WARNING
Damaged safety belts can break in a crash.
1l Use o nly th e co rrec t cle anin g so lu ti on s. Ne ver use gas­
oli ne or d ie se l fuel.
- Anyth ing that might damage yo ur sa fety
be lts could mean that you and your pas­
sengers would not be adequate ly pro ­
tected in an accident .
- Safety belt performance depends on co r­
rect insta llation. Never remove be lts
from the veh icle to clean them .
- Do not use chemical clea ning agents,
b leach or dyes . They have corrosive prop­
ert ies which wea ken the webb ing .
- When clean ing your safety be lts, inspect
them for damage . If you discover dam ­
age, see your Audi dea ler .
