appears in the display as well. The ASR can be deactivated at any
speed.
The ASR should normally be activated all the time . Only in certain
exceptional situations when some s lip is desirable does it make
sense to deactivate the ASR. Examples:
• when driving with tire chains
• when driving in deep snow or on loose ground and
• when rocking the vehicle loose after it has become stuck.
When the abnormal situation is over, you should activate the ASR
again.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i ] Tips
To ensure that the ASR works properly, al l four wheels must be fitted
with identical tires. Any differences in rol ling radius of the tires can
cause the system to reduce engine power when this is not desired.

Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending large ly on operating conditions and driving habits:::::>& .
On vehicles that are either driven mostly in stop-and-go city traffic
or are driven hard, the brake pads should be checked by your autho-
Intelligent technology
rized Audi dealer more often than specified in the Warranty & Main­
tenance booklet.
Fai lure to have your brake pads inspected can
resu lt in reduced brake performance .
On steep slopes, you shou ld use the braking effect of the engine.
This way, you prevent unnecessary wear on the brake system. If you
must use your brakes, do not hold the brakes down continuous ly.
Pump the brakes at intervals.
Moisture or road salt
If you are driving faster than 31 mph (50 km/h) and the windshield
wipers are on, the brake pads will briefly touch the brake discs in
regular intervals so as to improve reaction time when braking on
wet surfaces. You , the driver, wil l not notice anything.
Under certain conditions, for example, when driving th rough water
or very heavy rain , or even after washing your vehicle , the braking
effect can be reduced due to moisture (or in freezing conditions ice)
on the brake pads. A few careful brake applications should dry off
the brake pads or remove any ice coatings .
The ef fectiveness of the brakes can be reduced when the vehicle is
driven on a salt -covered road and the brakes are not used . Here too ,
you should clean off accumulated sa lt coating from brake discs and
pads with a few carefu l applications of the brake:::::>&.
Corrosion
There may be a tendency for dirt to build up on the brake pads and
corrosion to form on the discs if the car is not drive n regularly or
only for short trips with litt le use of the brakes .
I f the brakes are not used frequently, or if corrosion has formed on
the discs, it is advisable to clean off the pads and discs by braking
firm ly a few times from a moderately high speed:::::>& .
Faults in the brake system
If you shou ld notice a sudden increase in brake pedal travel, then
one of the two brake circuits may have failed:::::>&. ..,

[ i ] Tip s
The consumption estimates as published by ENVIRONMENTAL
PROTECTION AGENCY (EPA) and Transport Canada may not corre ­
spond to your actua l consumption on the road, which wi ll vary
depending upon vehic le load and speed, road and weather condi­
tions, trip length, etc .•
Drive smoothly and keep a tookout ahead
Vehicles use the most fuel when they are accelerating.
- Avoid unnecessary accelerating and brak ing.
Vehicles use the most fuel when they are accelerating . If you antici ­
pate what is going to happen next, you will need to brake less and,
thus, accelerate less. Let the vehicle coast whenever possible -for
examp le when you see that the next traffic ligh t is red .
Avoid full thrott e
Driving at moderate speeds saves fuel and improves your
mileage.
- Try and keep we ll below your car's maximum speed.
Acce lerating gently reduces fuel consumption, engine wear, and
does not disturb the environment .
Fuel consumption, exhaust emissions and engine noise increase
disproportionately at high speeds. If you drive at approximate ly
three quarters of top speed, fuel consumption will be reduced by
one half. Never drive faster than the posted speed limit and weather
conditions permit. •
Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
- Shut the engine off when you are not driving the vehicle.
-Do not warm up the vehicle by letting the eng ine run at
idle.
It makes sense to shut off the engine in traffic jams, when waiting
for trains to pass at rai lroad crossings, 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 sti ll warm ing up .
0 Note
Do not leave engine idling unattended after starting. If warning
lights should come on to indicate improper operation, they would
go unheeded . Extended id ling a lso produces heat, which could
resu lt in overheating 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 intervals.
By having your vehicle regularly serviced by an authorized Audi
dea ler helps to ensure that it runs properly and economically. The
condition of your vehicle not only affects its safety and abi lity to
hold its value, it also affects
f ue l co nsu mpti on.

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the right kind of
oil.
T he engine in your Audi is a sophisticated power plant that was built
to exacti ng specifications . This engine needs the right kind of
engine oil that meets specifications regarding qua lity and viscosity
so that it can run smoothly and reliably. 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 today
than it did years ago. Audi has developed a spec ial quality standard
for engine oi l that will help assure tha t your vehicle's engine will get
the lubr ication it needs for proper operation .
Modern engine lubrication has taken a quantum leap in the last few
years . Many synthe tic oi ls availab le today provide better engine
lubrication that can outlast traditional pet roleum-based oils ,
making them a smart choice for use throughout the life of your Audi.
Whether you use synthet ic or petroleum -based engine oil, the oi l
that you use must conform to Audi's oi l quality standard VW 502 00
to help keep your veh ic le's engine running smoothly and help prevent the formation of harmful deposits
, sometimes called
"sludge", that over time can lead to expensive repairs.
At the time of printing, engine oi ls avai lable in the U .S . and Canada
that meet the exacting specifications of Audi oil standard VW 502 00 are synthetic engine oils. This does not mean, however, that every
synthetic engine oil will meet Audi oil standard VW 502 00 . So
a lways be sure that you use an approved oi l.
To help prevent the formation of harmful deposits use only oil with
the fo llowing specifications printed on the oil container:
Audi oil sta ndard VW 502 0 0
Oil container labels may carry th e specification singly or in combi­
nation with o ther designa tions and oil quality standards.
Visc osit y
Engine oils are graded according to their viscosity . The proper
v iscosity grade oi l for your engine depends on c limactic or seasona l
conditions where you drive. You can use oil wi th a viscosi ty grade of
SAE 5W40 across al l temperature ranges for normal driving condi­
tions .
Howeve r, if engine oil viscosity grade SAE 5W40 is not available, you
can a lso use viscosity grade SAE 5W-30 or SAE 0W -40 as long as it
meets Audi oil qua lity standard VW 502 00 specifications.
Because engine o il that meets the Audi o il standard may not be
avai lable everywhere when you n eed it, we strongly recommend
that you a lways carry with you an extra quart (liter) of o il that
express ly conforms to the VW 502 00 specification, in case you have
to top off the oil while on the road .
Only if the level of the oil is at or below the minimum mark - and no
oi l that expressly conforms to Audi oil standard VW 502 00 specifi ­
cations is availab le - may you top o ff with a high qua lity engine oil,
preferably synthetic -based, that meets ACEA A3, ACEA A5 or
ACEA 85 or API SL specifications, but even then, on ly in viscosity
grades SAE 5W -40, SAE 5W -30, or SAE 0W -40. However, during the
en tire time between oil change intervals, never top off with more _,.

The fluid level may drop slightly after some time due to the auto­
m atic adjustment of the brake pads. This is not cause for alarm .
If the brake fluid level fal ls
considerably below the "MIN" mark , the
brake warning/indicator light (U.S. models :
BRAKE, Canadian models:
{(j))) will come on=> page 16 and => page 29. Do not continue to
operate the vehic le. The complete brake system should be thor ­
oughly checked by an author ized Audi dealer or qualified workshop
and the cause corrected . If the brake fluid level is too low, the brak e
warning/ind ica tor light will illuminate. Contact an authorized Audi
dea ler
immediatel y.
[ i J Tip s
The brake fluid reservoir is located underneath the cover. •
Changing brake fluid
Have the brake fluid changed by an experienced techni ­
cian.
Brake fluid absorbs moisture from the air . If th e water content in the
brake fluid is too h igh, corrosion in the brake system may result
after a period of time. The boi ling point of the brake fluid will also
decrease considerably and decrease braking performance .
Therefore , the brake fluid must be changed
ev ery tw o ye ars. Always
use new brake fluid which conforms to Federa l Motor Veh ic le Stan ­
dard "FMVSS 116 DOT 4".
T he brake fluid res ervoir can b e difficul t to reach, therefore, we
recommend that you have the brake fluid changed by your autho ­
rized
Audi de ale r. Your dealer has the correct tools, the right brake
fluid and the know -how to do this fo r you .

Battery
General information
Under normal operat ing conditions, the battery in your Audi does
not need any maintenance. With
high outside temperatures or long

T he correct tire pressure for the spare wheel is located on a label
either on the driver's side B -pi llar or inside the fuel filler flap.
Because technical changes may be made to vehicle equipment
during the mode l year, always compare the tire size designation on
the tire pressure label on your vehicle with the tires on your vehicle. Make sure that the tire size information on the vehicle labe l is the
same as the size of the tires on the vehicle. This is especially impor­
tant if the vehicle belongs to someone else or you bought the
vehic le with different rims/tires or you bought the vehicle as a previ ­
ously owned vehicle.
Remember, your safety and that of your passengers a lso depends
on making sure that load l imits are not exceeded. Vehicle load
includes everybody and everything in and on the vehicle . These load
limits are techn ically referred to as the vehicle's Gross Veh icle
Weight Rating ("GVWR"l. The Gross Axle Weight Rating ("GAWR"l is
the maximum load that can be applied at each of the vehicle's two axles. The Gross Vehicle Weight Rating and the Gross Axle Weight
Rating are l is ted on t he safety compliance sticker labe l located
either on the driver's side B-pillar or on the inside of the fuel fi ller

Checking tire pressure
The correct tire pressure for the tires originally installed
on your vehicle is listed on the tire pressure label located
either on driver's side B-pillar or inside the fuel filler flap .
The recommended tire pressures are on the ti re pressure label and
in the table=>
page 291, "Cold tire inflation pressure".This means
that the pressure must be checked and adjusted when the tire has
not been driven for more than a couple of mi les (kilometers) at low
speeds during the previous three hours. Air in the tires expands
when the tire heats up as a result of internal friction as i t flexes in
use. The tire pressure is higher when the tire has warmed up than
when it is "cold ."
It is the inflation pressure in a "cold" tire that counts. Therefore, you
should never let air out of a warm tire to match "Co ld tire inf lation
pressure" recommendations=>
page 291. The tires wou ld then be
underinflated and could fail suddenly. .,_
