Warning light in the instrument cluster
display
If the. warning light in the instrument clus ­
ter disp lay flashes, this can mean one of two
things: either the coolant
t empera ture is too
high, or the coolant
level is too low
¢ page 31.
If the needle is well in the upper area of the
gauge, the coolant temperature is too high.
Stop the vehicle, switch the engine off, and
allow it to cool.
If the warni ng light comes on
again after driving a short distance, contact
an author ized Audi dealer or other qualif ied
workshop.
_& WARNING
- Always observe the warning in
¢ page 230, Engine compartment, be­
fore opening the hood and checking the engine coolant level.
- Never open the engine hood if you see or hear steam, or if you see engine coolant
dripping from the engine compartment.
You could burn yourself . Let the engine
cool off first so that you cannot hear or
see any steam or e ngine coolant .
CD Note
-Mounting additional lights or accessories
in front of the a ir inlets reduces the cool­
ing effect of the rad iator. At high outside
temperatures or high engine load, the
engine could overheat .
- The front spo iler has been designed to
properly distribute the cooling air when
the veh icle is moving. If the spoiler is
damaged, this could reduce the cooling
effect and the engine co uld then over­
heat. Ask you r aut horized Aud i dealer for
assistance.
Tachometer (engine rev counter )
The tachometer indicates the engine RPM
(revolutions per minutes).
If engine RPM drops be low 1,500, you should
downshift to the next lower gear . Th e red area at
the end of the scale indicates maximum
perm issible eng ine RPM after the break-in pe­
riod. Before reaching this area, move these­
lector lever to position
D (Drive) or ease your
foot off the accelerator pedal.
CD Note
The tachometer needle @ ¢ page 10,
fig. 3
should on ly briefly be in the red
zone: you cou ld damage your eng ine! The
beginn ing of the red zone var ies depend-
i ng on the engine.
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise .

"t::7: Engine oil pressure malfunction
The red engine oil pressure warning symbol
requires immediate service or repair. Driving
with a low oil pressure indication is likely to
cause severe engine damage.
If the . symbo l on the d isplay flashes, the
engine oil pressure is too low. A driver mes­
sage appears as well to exp la in the malfunc­
tion in more detail. The driver warning goes

page 242.

If the engine does not start immediately, stop
trying after 10 seconds and then try to restart
the eng ine about 30 seconds later .
After a cold engine is star ted, there may be a
brief period of increased noise because oil
pressure must first bui ld up in the hydraulic
va lve adjusters. This is normal and not a cause
for concern.

- The brake booster and servotron ic only
work when the engine is runn ing . With
the ignition turned off, you have to apply
more force when steering or brak ing.
Since you can not steer and stop normal ­
ly, th is can lead to acc idents and serious
in ju ries .

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>

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 .
- Never spill flu ids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electr ic fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap when the eng ine is still warm. The cool­
ant system is pressur ized and hot coo l­
ant could spray out .
-Protect your face, hands and arm from
steam or hot eng ine coolant by placing a
thick rag over the cap when you open the coolant reservoir .
-If work on the fuel system or the electri­
cal system is necessary :
- A lways disconnect the battery.
- Never smo ke or work near heaters or
open flames . Fluids in the engine com ­
partment co uld start a fire.
- Keep an approved fire ext inguisher im­
mediately available.
- T o avoid ele ctrical shock and persona l in ­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repa ir
with the engine running:
- Fi rst, fully apply the parking bra ke,
move se lec to r l ever o f automat ic trans- mission to
"P" (Park); put manua l
transmission in Neutra l.
- Always use extreme caution to p revent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts. Tie back hair before
starting, and do not wea r clothing that
will hang o r droop into the engine.
- M inim ize exposure to em iss ion and
chemical hazards

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

(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

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.

not grip well on wet roads and increase
your risk of "hydroplaning" and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from t ires.
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds . Tir es that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on your vehicle if
you are not sure of their" previous histo ­
ry ." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
