A WARNING
-Always pay attention to traffic even when
the cruise control is switched on. You are
always responsible for your speed and
the distance between your veh icle and
other veh icles .
- For safety reasons, the cruise contro l
should not be used in the city, in stop­
and-go traffic, on twisting roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro­
planing) -risk of accident .
- Turn off the cruise control temporarily
when entering turn lanes, highway exit
lanes or in construction zones .
- Please note that inadvertently "resting"
your foot on the accelerator pedal causes the cruise control not to brake. This is
because the cruise control is overridden
by the driver's acceleration.
- If a brake system malfunction such as
overheating occurs when the cruise con­
trol system is switched on, the braking
function in the system may be switched off. The other cruise control functions re­
ma in active as long as the indicato r light
mmlm (US models) !Iii (Canadian mod­
e ls) is on.
(D Tips
The brake lights illuminate as soon as the
brakes decelerate automatically.
Changing speed
Applies to vehicles: wi th cruise co ntrol
• Press lever in the 0 or 0 direction
¢ page 77, fig. 79 to increase or decrease
your speed .
• Release the lever to
save that speed.
Change speed in in crements of 1 mph (1 km/
h) by lightly pressing the lever. If you keep the
lever pressed down, you will a lter your speed
in 5 mph (10 km/h) increments.
You can also press the accelerator pedal down
to increase your speed, e.g . if you want to

ESP includes and/or works together with the
anti-lock brake system (ABS) , brake assist sys ­
tem, anti -slip regulation (ASR) , e lectronic dif­
ferential lock ( EDL) and e lectronic interax le
d ifferential lock* . ESP is swi tched on all the
time. In certain situat ions when you need less
traction , you can switch off ASR by pressing
the button
[ru <::;> page 186, fig . 161 . Be sure
to switch ASR on again when you no longer
n eed less t raction.
Anti-lock br aking s ystem (ABS)
ABS prevents the wheels from locking up
when braking . The veh icle can still be steered
even during hard braking . Apply steady pres­
sure to the brake pedal. Do not pump the ped ­
a l. A puls ing in the bra ke peda l indicates that
the system is he lping you to brake the vehicle.
Brake assist system
The brake assist system can decrease brak ing
d istance.
It increases braking power when the
d river p resses the brake pedal quic kly in emer­
gency situations. You must press and ho ld the
b rake peda l until the situation is over. In vehi­
cles with adaptive cruise control*, the brake
assist system is more sensitive if the distance
detected to the vehicle ahead is too small.
Anti -slip regulati on (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road conditions. This makes it easier to
start, accelerate and drive up hills .
Electronic differential lock (EDL )
The ED L brakes wheels that are spinn ing and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-whee l drive* . This function is available up
to about 75 mph (120 km/h).
I n extreme cases, ED L automat ica lly switches
off to help keep the brake on the braked whee l
from overheating . EDL will switch on again au ­
tomatically when conditions have returned to
normal.

Electronic intera xle differ ential l ock */
s el ecti ve w heel torque cont rol *
The electronic interaxle differential lock (front
whee l drive) or the se lective whee l torque
control (all-wheel dr ive) operates when dr iv­
ing through curves . The front wheel on the in­
s ide of the curve or both wheels on the inside
of the curve are braked selectively as needed .
T his min imizes sliding in the front wheels and
allows for more p recise d riving through
curves . T he applicable system may no t acti­
vate when driv ing in wet or snowy conditions.
A WARNING
-
- ESP , ABS, ASR, EDL and the e lectronic in­
teraxle diffe rential lock function* cannot
overcome the laws of physics. This is es­
pecially important on slippery or wet
roads . If the systems begin acting to sta­
bilize your veh icle, you shou ld immedi­
ately change you r speed to match the
road and traffic cond itions. Do not let
the increased safety provided by these
systems tempt you to take risks. Do ing
so will increase the risk o f a loss of vehi ­
cle control, collision and serious persona l
inju ries.
-A lways adapt your speed to road, traffic
and weather conditions . The risk of los ­
ing control of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead . ESP, ABS, the brake ass ist system,
EDL, ASR and the e lectronic interax le dif­
fe rential lock fu nction* cannot prevent
coll is ions .
- Always accelerate with spec ial care on
even, smooth su rfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with these assistance systems that cannot al­
ways he lp to red uce the risk of loss of ve -
hicle control. .,.

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 discharged .
If starting capability is jeopardized due to en­
ergy consumption, the following warning ap­
pears in the MMI display :
Please start the engine soon or the system
will be turned off.
The warning indicates that the system will be
turned off automatically after 3 minutes . If
you wish to continue using the functions , you
have to start the engine.
With the engine running
Although electrical energy is generated when
the vehicle is being driven , the battery can be ­
come discharged . This happens mostly when
little energy is being generated and a great
deal consumed and the battery's state of
charge is not optimal.
To bring the energy balance back into equili­ brium, consumers which require especially
large amounts of energy are temporarily cut
back or switched off . Heating systems in par­
ticular require 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 temporarily cut back or switched
off. These systems will be available again as
soon as the energy balance has been restored.
You will also notice that engine idle speed has
been increased slightly. This is normal and not
a cause for concern . By increasing engine idle
speed the additional energy required is gener­
ated and the battery is charged.

Catalytic converter
It is very important that your emission con­trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
.. Always use lead-free gasoline¢ page 211,
Fuel supply.
.,. Never run the tank down all the way to
empty.
.,. Never put too much motor oil in your en-
gine
¢ page 221, Adding engine oil~-
.,. Never try to push- or tow-start your veh icle.
The catalytic converter is an eff icient "clean­
up" device built into the exhaust system of
the vehicle . The catalytic converter burns
many of the pollutants in the exhaust gas be ­
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critically
importa nt for the life of the cata lytic convert­
e r 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
man ifold, exhaust pipes, catalytic con­
verter or heat shields. During driving, the
substance used for undercoating cou ld
overheat and cause a fire.
0 Note
- Be aware that just one tank filling with
leaded fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil level
¢ page 221.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis­
fire . U nburned fuel could a lso get i nto
Dri vin g and en vironm ent 193
the exhaust system and this cou ld cause
the catalytic converter to overheat .
- Do not switch off the ignit ion while the
vehicle is mov ing.
- Do not continue to ope rate your veh icle
unde r these conditions, as othe rwise fuel
can reach the catalytic converter. This
co uld result in overheating of the con­
verter, requir ing its replacement .
- To assure efficient operation of the Emis ­
sion Control System:
- H ave your vehicle maintained prope rly
and in accordance w ith the se rv ice rec­
ommendat ions in you r Warranty &
M aintenance boo klet.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle w il l impair
the function of the em ission contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control System is
operat ing properly, the exha ust gas can
have a sul fur -li ke exhaust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or filling the tank with lead-free super
grade gasoline .
Avoid damaging the
vehicle
When you are drivi ng on poo r roads, or over
c ur bs, s teep ramps, etc., ma ke certai n that
low -lying parts s uch as spoilers and exhaust
system pa rts do not bottom o ut and get dam­
aged.
T h is is espec ially true for veh icles w ith low­
s lung chassis (spor ts chassis)* and fully load­
ed vehicles. •

Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
"" Try and keep well below your car's maxi-
mum speed.
Accelerating gently reduces fuel consump­ tion, engine wear, and does not disturb the
environment.
F ue l consumption, exhaust emissions and en ­
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will be reduced by one half. Never drive faster
than the posted speed limit and weather con­
d itions permit .
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 veh icle by letting the
engine run at idle .
It makes sense to shut
off the engine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings, or at traffic lights that have
l ong wa its on red. Turning the engine
off fo r
just
30-40 seconds saves more fue l than is
bu rned starting the eng ine again .
It takes a long time for the engine to warm up
fu lly when it is running at idle. However, wear
and nox ious em issions 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
would go unheeded. Extended idling also produces heat, which cou ld result in over-
Dri vin g and en vironm ent 195
'
heating o r othe r damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
"" Have your veh icle serviced at reg ular i nter-
vals.
By having your vehicle regu larly serviced by an
Audi dealer he lps to ensu re that it runs prop­
erly and economically. The condition of your
vehicle not only affects its safety and ability to
hold its value, it a lso affects
fuel c onsump ­
tion .
Ch eck you r o il e ach time you fill your tank .
The amount of o il used is re lated to eng ine
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 vehicle 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.
(U) Note
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Ma in­
tenance booklet . Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
em iss ion 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 manufacture r.
- Do not alter or remove any device, such
as heat shie lds, swit ches, ign ition w ires,
valves, which are designed to p rotect
your vehicle's Emission Control System
and other important vehicle compo­
nents .

210 Cleaning and protection
-When cleaning your safety belts, inspect
them for damage.
If you discover dam­
age, see your Audi dealer .
- Always read and heed all WARNINGS and
other information
c> page 200.
Engine compartment
Be especially careful when cleaning the en­
gine compartment.
Always switch off the ignition before clean­
ing the engine
c> .&..
Plenum panel
Remove leaves from the plenum pane l in front
of the windsh ield under the engine compart­
ment. This prevents the water dra in ho les
from becoming blocked, and it prevents de­
bris from entering the vehicle interior through
the heating and venti lation ducts .
Corrosion protection
The engine compartment and transmission
have been corrosion -protected at the factory.
Good ant i-corrosion treatment is very impor­
tant, particularly in the winter. If the veh icle
is frequent ly driven on salt treated roads , the
enti re engine compartment and plenum panel
should be thoroughly cleaned at the end of
winter and retreated to prevent sa lt damage.
At the same time, the underside of the vehicle
should be washed as we ll.
If the engine compartment is cleaned at any
time with grease removing solutions
1l, or if
you have the engine washed, the anti-corro­ sion treatment is a lmost always removed as
well. It is therefore essential to have a long­ lasting corrosion protection reapplied to all
surfaces, seams, joints and components in the
engine compartment .
1l Use o nly the co rrect cle anin g so lu ti on s. Ne ver use gas­
o lin e or d ie se l fuel.
A WARNING
Be aware: The eng ine compartment of any
motor vehicle is a potentially hazardous
area .
- Before work ing in the engine compart­
ment, be sure to read the information
c> page 216.
-Before reach ing into the front panel, al ­
ways sw itch off the ignition . Otherwise,
the windshield wiper system could unin­
tentionally be switched on, possibly
causing personal injury from the moving
wiper linkage .
- Never reach into the area around or
touch the radiator fan. The auxiliary fan
is temperature controlled and can sw itch
on suddenly -even when the ignition is
off.
- Do not wash, wax or dry the engine with
the engine running . Moving or hot parts
could injure you.
- Do not clean the underside of the chas­
sis, fenders, wheel covers, or other hard
to reach parts without protecting your hands and arms . You may cut yourself on
sharp-edged metal parts.
-Always read and heed all WARNINGS and
other information
