Anti-loc k br aking sy stem (ABS )
ABS prevents the wheels from locking up when
brak ing . T he vehicle can st ill be stee red even dur ­
ing hard braking. App ly steady pressure to the
brake peda l. Do not pump the peda l. A pulsing in
the brake pedal indicates that the system is help­
ing you to brake the vehicle.
Brake assist sy ste m
The brake assist system can decrease braking dis ­
tance. It increases braking power when the dr iver
presses the brake pedal quick ly in emergency sit­
uations. You must press and ho ld the brake pedal
until the situation is over.
Anti -slip regulation (ASR )
ASR reduces engine power when the drive whee ls
begin to spin and adapts the force to the road
conditions. This makes it easier to start, acceler ­
ate and dr ive up h ills.
Electronic diff erential lock (EDL )
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive wheel or wheels if the vehicle is equipped w ith all-whee l
drive*. This function is available up to about 60
mph (100 km/h) .
I n extreme cases , EDL automatically switches off
to help keep the brake on the braked wheel from
overheating . EDL wi ll switch on again automati­
cally when conditions have returned to normal.
A WARNING
- ESC, ABS, ASR and EDL cannot overcome the
laws of phys ics. Th is is especially important
on slippery or wet roads. If the syst ems be­
gin act ing to stab ilize your vehicle, you
sho uld immediately cha nge your speed to
match the roa d and traffic con ditions. Do
not let the increased safety provided by
these systems tempt you to take risks . Do­
ing so wi ll increase the risk of a loss of vehi­
cle contro l, collis ion and serio us personal in­
juries .
- Always adapt your speed to road, traffic and
weather cond it ions. The risk of losing con­
tro l of the veh icle increases when driving
Int ellig ent t echnolo gy
too fast, especially through curves and on
slippery or wet roads, and when dr iving too
close to vehicles up ahead. ESC, ABS, the
brake assist system, EDL and ASR cannot
prevent coll is ions .
- Always accelerate with special care on even,
smooth surfaces such as those that are wet
or covered with ice and snow. The drive
wheels can spin even with these assistance sys tems that cannot always help to reduce
the risk of loss of veh icle control.
(D Tips
- ABS and ASR only wo rk correctly when all
four wheels are eq uipped with ident ical
tire s. Different tire s izes can lead to a reduc­
t ion i n engine power.
- Yo u may hear noises when the systems de­
sc ribed a re wo rking.
- If the ind icator light GJ or II (USA mod­
els) ;tiJ (Canada models) appea rs, there
may be a malfunction~

Switching on/off
ESC turns on automatically when you start the
engine.

In certain situations, it might make sense to a l­
low some slip. For example:
- Rocking the vehicle to free it when it is st uck
- Driving in deep snow or on loose gro und
- Dr iving with snow chains

The exclusive use of unleaded fuel is critically im­
portant for the life of the catalytic converter and
proper functioning of the engine.
A WARNING
- Do not park or operate the vehicle in areas where the hot exhaust system may come in contact with dry grass, brush, fuel spill or
other material which can cause a fire .
- Do not apply additional undercoating or
rustproofing on or near the exhaust mani­
fold, exhaust pipes, catalytic converter or
heat shields. During driving, the substance
used for undercoating could overheat and
cause a fire.
([) Note
-Be aware that just one tank filling with lead­
ed
fuel will already seriously degrade the
performance of the catalytic converter.
- Do not exceed the correct engine oil level
~page 160.
- Do not drive until the fuel tank becomes
completely empty. The engine could misfire.
Unburned fuel could also get into the ex­
haust system and this could cause the cata­
lytic converter to overheat.
- Do not turn off the ignition while the vehicle
is moving.
- Do not continue to operate your vehicle un­
der these conditions, as otherwise fuel can
reach the catalytic converter. This could re­
sult in overheating of the converter, requir­
ing its replacement.
- To assure efficient operation of the Emission
Control System:
- Have your vehicle maintained properly and in accordance with the service recommen­
dations in your Warranty
& Maintenance
booklet.
- Lack of proper maintenance as well as im­
proper use of the vehicle will impair the
function of the emission control system
and could lead to damage.
Driving and environment
{® For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. This depends on the sulfur
content of the fuel being used. Using a differ­
ent brand of fuel may help, or filling the tank
with lead-free super grade gasoline .
Shutting down vehicle
If you would like your vehicle to remain inopera­
tive for a longer period of time , contact an Audi
or other specialized dealer. They can advise you
on necessary precautions e.g. corrosion preven­
tion, maintenance and storage. Pay attention to
additional information concerning the battery.
Refer to~
page 164.
Operation and
maintenance
Fuel economy, environmental impact, and wear
on your engine, brakes and tires largely depend
on three factors:
-your personal driving style
- operating conditions
- technical limitations
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 consump­
tion.
The amount of oil used is related to engine load
and speed.
It is normal for the oil consumption of a new en­
gine to reach its lowest value after a certain mile­
age has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly as­
sess oil consumption .
This also applies to fuel consumption and engine output . .,,.

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.
T he coo ling system is sealed and genera lly re­
quires little attention.
The cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed. The coolant consists of a mixtu re of
specially conditioned wate r and the manufactur­
er's glycol-basedcoolant additive Gl3 antifreeze
with anticorrosion additives (50% for USA mod­ els; 60% for Canadian models). This mixture both
assures the necessary frost protection and pro­
tects metal components in the engine's cooling
system from corrosio n and scaling. It also ra ises
the boiling point of the coolant .
