With the engine turned off
If you listen to the radio, for example, with
the engine turned off or use other MMI func­
tions, the battery is being d ischa rged.
I f starting capability is jeopardized due to en­
e rgy consumpt ion, the following warning ap­
pears in the MMI display:
Please start engine, otherwise system will
switch off in 3 minutes.
The warning ind icates that the system will be
turned off automatically after 3 minutes. If
you wish to cont inue using the functions, you
have to start the engine.
With the engine running
Although electrical energy is generated when
the vehicle is be ing driven, the battery can be­
come discharged . Th is happens mostly when
little energy is be ing generated and a great
deal consumed and the battery's state of
charge is not optimal.
To br ing the energy balance back into equili ­
brium, consumers which require especially
l arge amounts of energy are temporarily cut
back or swit ched off. Heating systems in par­
t icular requ ire a great deal of energy.
If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporari ly cut back or switched
off. These systems will be avai lab le again as
soon as the energy balance has been restored.
You will a lso notice that engine idle speed has
been increased slightly . This is norma l and not
a cause for concern . By increasing 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, this
Intelligent technology 229
is shown in the instrument cluster display
with the following driver message:
(•) I.ow battery charge: battery will be
charged while driving
T h is not ificat ion reminds you that the start ing
capability of the engine may be limited. As
soon as you start driv in g again, the battery
will be recharged and the not ific at ion w ill go
out.
Driver notification appears and goes out
again
If t his driver notification appears after the ig­
nition is tu rned 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 notification appears after the ig­
nition is turned on or whi le driving and does
not go out again, the battery's state of charge
is not in the optimal range. Starting ab ility is
restricted . Have the battery checked as soon
as possible by an authorized Aud i dealer or

Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
11-Shut the engine off when you are not driving
the vehicle.
11-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 cross ings, or at traffic lights that have
long waits on red. Turning the engine
off for
just 30-40 seconds saves more fuel than is
burned starting the engine 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 .
11-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
ab ility to hold its value, it also affects fuel
consumption.
Check your oil each time you fill your tank.
Driving and environment 233
The amount of oil 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 certain
mileage has been driven.
You must drive your vehicle about 3,000 miles
(S,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
t enance booklet. Lack of prop er mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission cont ro l system and could 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 .
11-Try to avoid driving short distances w ith a
cold engine.
T he 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/l00km). After about a
half a mile, fuel economy climbs to 12 mpg
(20 l/100 km). After about
2.5 miles (4 km), liJI,

Trailer towing weights
W ith a factory-installed tra iler hitch, the
maximum permissible trailer we ight is 6,600
l bs (3,000 kg). The maximum permissible un­
braked trailer weight is 1,650 lbs (750 kg).
With an
aftermarket trailer hitch, the maxi­
mum permissible t railer we ight is 5,500 lbs
(2,500 kg). These specifications apply when
driving on roads having an incline of less than
12%.
Permissible tongue load
For best vehicle handling under these
changed cond itions, adjust the trailer load so
that the tongue load is at the maximum al­
l owable or slightly lower. You can get an ap­
prox imation of the tongue load with a bath­
room scale or you can measure the load at a
trucking company or weighing station .
With a
factory-installed tra iler hitch, the
maximum permissible load on the ball hitch
Trailer towing 239
may not exceed 660 lbs (300 kg). With an af­
termarket
trailer hitch, the maximum permis ­
s ib le load on the ba ll hitch may not exceed
550 lbs (250 kg).
It is recommended to use
the maximum permissible load.
Trailer load distribution
Be sure the load in the trailer is held secure ly
in place to prevent it from shifting forward,
backward or sideways.
Never allow a passenger to ride in a trailer
¢.& in Driving instructions on page 240.
Ball mount
The trailer hitch may only be used w ith suita­
ble ball mount and ball ¢
fig. 232. Installa­
t ion of the hitch ball must be carried out in ac­
cordance with the manufacturer's instruc­
tions. At the height dimension of 1.5 in
(38.5 mm) a tolerance of+/- 0.5 in (12 . 7 mm)
is perm issib le.
Engine cooling system
Towing a trailer makes the engine work hard­
er . It is important that the cooling system's
performance is up to the additional load .
Make sure that the cooling system has enough
fluid .
Tire pressure
When towing a tra iler, inflate the tires of your
vehicle to the cold tire pressure listed under
" Full load" on the tire pressure label. The tire
pressure label is located on the driver's side B­
pillar . Inf late trailer tires to trai ler and t ire
manufacturers' spec ificat ions .
Lights
The headlight settings sho uld be checked with
the trailer attached before driving
off . Check
to make sure both vehicle and trailer lights
are working properly .
Safety chains
Be sure trailer safety chains are properly con­
nected from the trailer to the hitch on the

Using the proper engine oil is important for
the functionality and service life of the en­
g ine. Your engine was factory -filled with a
h igh-quality oil which can usually be used
t h roughout the entire year.
Your Limited New Vehicle Warranty does not cover damage or ma lf u nctions due to
fa ilure to follow recommended mainte­
nance and use requirements as set forth in
the Audi Owner's Manual and Warranty
&
Ma intenance booklet .
- Use only a high quality eng ine oil that ex­
pressly complies w ith the Audi o il quality
sta ndard specified for your veh icle's e n­
gine . U sing any other oil can cause seri­
ous eng ine dam age.

Eng ine oil consumption
To provide effect ive lub rication and cooling for
internal engine pa rts, all inte rnal combust ion
engines use some oil. Oil consumption varies
Checkin g and fillin g 259
from engine to engine and may change ove r
the life of the engine. Engines tend to use
more o il during the break-in period than they
do afterward, when o il cons umption has sta­
bili zed. Depending on the way the vehicle is
driven and the operati ng conditions, oil con ­
sumption can be up to 1 quart per 1,200
mil es(! lite r per 2,000 km) . Consumption
may be higher wi thin the fi rs t 3,000 m iles
(5,000 km) .
Un der normal cond itions, the rate of oil con­
sumption depends on o il quality as well as v is­
cosity, engine speed (rpm), outs ide tempera­
ture, road condi tions, the amount of oil d il u ­
t ion caused by condensed water or fue l resi­
due, and oxidation of the oi l. Oi l consump tion
may inc rease with engine wear over time, un ­
ti l replacement of worn engine parts may be ­
come necessary.
Beca use of all these variables, there is no
standard or "norma l" rate of o il cons umption .
We urge you to check the engine oil le vel at
regular intervals, p referably e very time you
fill the fuel tank, and always before a long
trip .
The oil p ressure wa rning light. is not an
indicato r of low engine oil le vel. If the wa rn ­
ing light does not go out after starting, or
flash es while dri ving (above 1500 rpm ), a
buzzer will sound . It indicates that the oil
pres sure is too low. Stop the engine immedi­
ately, che ck the engine oil level and add oil if
n ec ess ary. If the engine oil level i s normal,
but the light continues to flash , do not keep
driving or let the engine idle, as dam age may
occur .
If you believe yo ur engine uses too much o il,
we recommend that you consul t your author ­
ized Audi dea ler so that the ca use of yo ur con­
cern can be proper ly diagnosed . Keep in mind
that acc urate measurement of oil consump­
tion req uires great care and may take some
time . Your Audi dealer h as ins truc tions for
how to measure oil consumption accurately .

Coolant lo ss
Coolant loss may indicate a l ea k in t he cooling
system. In the event of coolant loss, the cool ­
ing system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant.
I n a
se ale d system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
A WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps.
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag .
- Turn the cap slowly and very carefully in
a counter-clockwise direction wh ile ap­
