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>

230 Cleaning and protec tio n
• Dab at the stain . Start at the outside and
work inwards .
• Once the stain is no longer visible, use a
soft dry cloth or t issue to soak up the mois­
ture.
Do not use leather cleaning products on Al­
cantara ®.
You may use a suitable shampoo for removing
dust and dirt .
Dust and gr it in the pores and seams can
scratch and damage the surface. If the car is
l eft standing in the sun for long periods, the
A lcantara ® should be protected against direct
sunlight to prevent it from fading. Slight color
variations will develop in normal use and are not an indication of material deterioration .
- Never use chemical solvents (e.g . lighter
fluid, turpentine), waxes, shoe polish or
s imilar products on Alcantara ® surfaces .
- To avoid damage, have stubborn stains
removed by a commerc ial cleaning spe­
cia list.
- Do not use br ushes, stiff sponges or sim­
i larly abrasive cleaning aids.
Safety belts
Only well-maintained safety belts work relia ­
bly when needed.
• Keep be lts clean.
• For cleaning, use a mild soap and water sol­
ution. Let be lts dry thoroughly and away
from direct sunlight.
• Do not allow inertia reel safety belts to re­
tract before they are completely dry.
• Check the condition of your safety belts
reg­
ularly.
Heavily soiled safety belts may not retract
properly .
A WARNING
Damaged safety belts can b reak in a crash . -
Anything that might damage your safety
be lts could mean that you and your pas­
sengers would not be adequately pro­
tected in an accident.
- Safety belt performance depends on cor­
rect insta llation. Never remove be lts
from the veh icle to clean them .
- Do not use chemical clean ing agents,
bleach or dyes. They have corrosive prop­
erties which weaken the webb ing.
- When clean ing your safety belts, inspect
them for damage . If you discover dam­
age, see your authorized Audi dealer .
- Always read and heed all WARNINGS and
other information

' Engine compartment
Be especially careful when cleaning the en­
gine comportment.
Alwa ys switch off the ign ition before cle an­
i ng the eng ine
c> .&, .
Plenum pan el
Remove leaves from the plenum panel in front
of the windshield under the engine hood . This
prevents the water drain holes from becoming
blocked, and it prevents debris from enter ing
the vehicle interior through the heating and
ventilat ion ducts.
Cor rosi on protec tion
The engine compartment and transmission
have been corrosion -protected at the factory .
Good anti- corrosion treatment is very impor­
tant, particu larly in the w inter.
If the vehicle
is frequently driven on salt treated roads, the
entire engine compartment and plenum panel
shou ld be thoroughly cleaned at the end of
winter and retreated to prevent salt damage.
At the same time, the underside of the vehicle
should be washed as well. ..,_

238 Check ing and filling
- Apply the parking brake.
- Move selector lever of automatic trans- mission to "P" (Park); put manual trans­
mission in Neutral.
- Always let the engine coo l down . Hot
components will burn skin on contact.
- To reduce the risk o f being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment. Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood.
- Keep children away from the engine com­
partment .

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil .
The engine in your Audi is a sophisticated
power plant that was bu ilt to exacting specifi­
cations . This eng ine needs the right k ind of
engine oil that meets specifications regarding
quality and viscosity so that it can run
smooth ly and reliab ly. Choosing the right oil
and changing oil within the time and mileage
intervals printed in your vehicle's Warranty
&
Maintenance booklet matters a lot more to­
day than it did years ago . Audi has developed
a specia l quality standard for engi ne oil that
will help assure that your vehicle's engine will
get the lubrication it needs for proper opera-
tion. .,..

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

(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

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.

244 Checking and filling
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
quires little attention .
The cooling system has been filled at the fac­ tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly ­
col-basedcoolant additive G12++ antifreeze
with anticorrosion add itives (SO% for USA
models; 60% for Canadian models). This mix­
ture bo th assures the necessary frost protec­
tion and protects metal components in the
engine's coo ling system from corrosion and
scaling. It also raises the boiling point of the
coolant.
Do not reduce the concentration of the cool­
ant in the summer by adding plain water .
The
proportion of coolant additive must be at
least 50 % but not more than 60%
to main­
tain antifree ze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi ­
cle heating and engine cooling system .
For year-round driving, antifree ze is added at
the factory for temperatures down to:
- - 31°F (- 35 °C) USA
- -40°F ( - 40°C) Canada.
You can mix the G12 ++ coolant additive with
other additives (G12+ or G12). Always check
with your authorized Audi dealer.
_&. WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ¢
A in Working in the engine
compartment on page 237.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in your vehicle is sufficient to meet the cli
­
mate conditions. This is especia lly impor­
tant if you live in a reg ion where the win ­
ter is extreme ly cold. If necessary, in­
crease the proportion of coolant additive
to 60% .
- When adding coolant additive to your
cooling system, remember :
- We recommend using only coolant ad­
ditive G12++ (check the label) for your
vehicle . This coolant additive is availa­
b le at authorized Audi dealers . Other
types of antifreeze can significant ly re­
duce corrosion protection. The result­
ing corrosion can cause a loss of cool­
ant and serious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Add ing radiator repair fluid may adverse ­
ly affect the function and performance of
your cooling system and cou ld resu lt in
damage not covered by your New Vehicle
Limited Warranty.
