A WARNING
-Always adapt your driving to the traffic flow.
- Only use the Launch Control Program when road and traffic conditions allow it and oth­
er drivers will not be endangered or an­
noyed by your driving and the veh icle's ac­
celeration .
- Please note that the dr iving wheels can spin
and the vehicle can break away whe n sport
mode/offroad mode is switched on, espe­
ci al ly when the road is slippery.
- Once you have accelerated, you should
switch spo rt mode/off road mode off by
pre ssing the
l.$ OFFI b utton .
@ Tips
- The transmiss ion temperature may increase
s ignificantly after us ing the Launch Con trol
P rogram. If that happens, the p rogram may
not be available for a few minutes. It w ill be
available again after a cool-down period.
- When a ccele rating using the Lau nch Control
program, all veh icle parts are subject to
heavy loads . This can resul t in inc reased
wear .

Inte llig ent Techn olo gy
In extreme cases, EDL automatically switches off
to help keep the brake on the braked wheel from
overheating. EDL will switch on aga in automati­
cally when conditions have returned to normal.
St eer ing r ecomm endation
The ESC helps to stabilize the vehicle by chang ing
the steering torque .
I n vehicles with dynamic steering*, ESC also
helps to stabilize the stee ring in critical situa­
tions.
Electron ic inter axle differential lock*/
sel ective whe el t orque control *
The electronic interaxle differentia l lock (front
wheel drive) or the selective wheel torque control
(a ll whee l drive) operates when driving through
curves . The front wheel on the inside of the curve
or both wheels on the inside of the curve are
braked selectively as needed. This allows more
precise driving in curves. The applicable system
may not activate when driving in wet or snowy
conditions.
.,&. WARNING
- The ESC and its in tegrated systems canno t
overcome the laws of phys ics. This is espe­
c ially important on slippery or wet roads.
If
the systems begin acting to stabilize your
Switching on /off
vehicle, you should immediately change
your speed to match the road and traffic
conditions. Do not let the increased safety
provided by these systems tempt you to
take risks. Doing so will increase the risk of
a loss of vehicle control, collision and seri­
ous personal injuries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of los ing con­
trol of the vehicle increases when driving
too fast, espec ially through curves and on
slippery o r wet roads, and when driving too
close to vehicles up ahead . The ESC and its
integrated systems cannot always prevent
collisions -there is still a risk of accidents!
- Always accelerate with specia l 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
systems that cannot always help to reduce
the risk of loss of vehicle control.
@ Tips
- ABS and ASR only work correct ly when all
four wheels are equipped with identical
t ires. Different tire sizes can lead to a reduc­
t ion in engine power.
- You may hear noises when the systems de­
scribed are working.
ESC turns on automatically when you start the engine .

Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels.
F ue l economy, environmenta l impact, and we ar
on your engine, brakes and tires la rgely depend
on three factors :
- you r persona l dr iving sty le
- operating conditions
- technical lim itations
If you anticipate what you need to do next and
drive economically, you can eas ily cut your fue l
consumption by
10-15 percen t. This section will
g ive you some tips on how you can help the envi ­
ronment and yo ur pocketbook .
(!) Tips
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not cor re­
spond to your actual consumption on the
road, which will va ry depending upon vehicle
load and speed, road and wea ther condi tions,
t rip length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
" Avoid unnecessary accelerating a nd braking .
Veh icles use the most fuel when they are acceler ­
ating . If you anticipate what is going to happen
next , you will need to brake less and, thus, accel­
e rate less . let the vehicle coast wheneve r possi ­
b le -fo r example when yo u see that the next traf­
fic light is red .
Driving and the envir onment
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage .
"Try and keep well below your car 's maximum
speed.
Acce lerating gently reduces fuel consumption,
engine wear, and does not disturb the environ­
ment.
Fuel consumption, exhaust emissions and engine
noise increase disproport ionately 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 cond itions permit .
Reducing unnecessary idling
Even when your car is jus t idling it burns up fuel.
" Shut the eng ine off when you are not driving
the vehicle.
" Do not warm up the vehicle by lett ing the en-
gine run at idle.
It makes sense to shut off the engine in traffic
jams, when waiting for trains to pass at railroad cross ings, or at traff ic lights that have long waits
on red . Turning the engine off for just
30 -40 sec ­
onds saves more f uel than is burned starting the
. . engine again.
It takes a long time for the eng ine to warm up
fully when it is running at idle . However, wear
and noxious emissions are especially h igh when
the engine is warming up . So yo u should dr ive
away as soon as you start the eng ine and avoid
runn ing at high rpms w hile the engine is st ill
warming up .
(D Note
Do not leave eng ine idling unattended after
s tart ing. If wa rning lights sho uld come on to
i ndicate improper operation, they would go
unheeded . Extended idling also prod uces
heat, which could resu lt in overheating or
other damage to the vehicle or other proper­
ty.

Check ing and F illing
@ For the sake of the environment
- Under no circumstances can the oil come in
contact with the sewage network or the soil.
- Observe and fo llow legal regulations when
disposing of empty oil containers .
Changing the engine oil
We recommend that hove your oil changed by on
authorized Audi dealer or a qualified service sta­
tion .
Before you che ck anything in the eng ine compart ­
ment,
always read and heed all WARNINGS ¢ A
in Working in the engine comportment on
page 203.
The engine oil must be changed according to the i n tervals specified in your Warranty
& Mainte­
nance booklet . This is very important because the
lubricat ing propert ies of oil diminish gradually
during normal vehicle use.
Under some circ umstances the eng ine oi l sho uld
be changed more frequently. Change oil more of­
ten if yo u drive most ly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traffic cond it ions , or have your vehi­
cle where temperatures remain below freezing
for extended periods .
Detergent additives in the oil will make fresh oil
look dark after t he engine has been run ning for a
short t ime . T his is normal and is not a reason to
cha nge the oil mo re often than recommended .
Because of the prob lem of proper disposal, along
with the special tools and necessary expertise re­
qu ired, we strongly recommend that you have
your oil c hanged by an aut ho rized
Audi dealer o r
a qualif ied se rvice station .
If you choose to change your o il yourself , please
note the following important informat ion:
A WARNING
To re duce the risk of pe rsonal injury if you
must c hange t he engine oil in your ve hicle
yo urs elf:
- W ear eye protection .
208
-
-To reduce the r is k of burns from hot engine
oil, let the engine cool down to the touch .
- W hen removing the oil drain plug with your
fingers, stay as far away as possible. Always
keep your forearm pa rallel to the ground to
he lp prevent hot oil from run ning down your
arm .
- Drain t he oil into a container designed for
this purpose, one large enough to hold at
leas t the tota l amou nt of oil in you r engine.
- Engi ne oil is poisonous . Keep it well out of
the reach of childre n.
- Continuous contact wit h used engine o il is
ha rmf ul to your skin. Always protect your
skin by washi ng oil
off thoroughly with soap
and wate r.
(D Note
Neve r mix oil additives with yo ur engine oil.
These additives can damage your e ngine and
adverse ly affect your A udi L imi ted New Vehi ­
cle Warranty .
@ For the sake of the environment
-Be fore chang ing you r oi l, first make sure
you know where you can properly dispose o f
t h e used oil.
- Always dispose of used e ngine o il pro perly .
Do not d ump it on garden so il, wooded
areas, into op en streams o r down sewage
drains.
- Recycle used e ngine o il by tak ing it to a used
eng ine oil collect io n fa cil ity in you r area, o r

Cooling system
Coolant '
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from free zing in the winter.
The coolin g system is sealed and generally re­
quires little attention .
The coo lin g sys tem h as been filled a t the fac to ry
wi th a pe rmanent coolan t which does not need to
be changed. The coo lant consists of a mixture of .,.

Check ing and F illing
blink until you add coolant and the level has been
restored to normal. Even though there is an e lec ­
tr ic coolant level sensor, we still recommend you
check the coo lant level from time to time.
Coolant los s
Coolant loss may indicate a l e ak in the cooling
system. In the event of coolant loss, the cooling
syst em should be insp ected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant.
I n a
s e aled system, losses can occur only if the
boiling point of the coo lant is exceeded as a re­
sult of overheating.
A WARNING
The cooling system is under pressure and can get very hot. Reduce the risk of scalding from
hot coolant by following these steps.
- Turn off the eng ine and allow it to cool
down .
- Protect your face, hands and arms from es­
caping fluid and steam by covering the cap
with a large, thick rag.
- Turn the cap slowly and very carefully in a
counter-clockwise direction wh ile apply ing
l ight, downward pressure on the top of the
cap .
- To avo id being burned, do not sp ill anti ­
freeze or coolant on the exhaust system or
hot eng ine parts . Under certain conditions,
the ethy lene g lycol i n engine coolant can
catch fire.
{Q) Note
Do not add any type of radiator leak seala nt
to your veh icle's engine coolant . Adding radia­
to r repa ir fluid may adversely affec t the func­
tion and performance of yo ur cooling system
and could result in damage not covered by
your New Vehicle Limited Warranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anyth ing in the eng ine compart­
ment,
a lwa ys re ad an d heed all WARNINGS

or in an emergency Gl2+. Do not use a
different additive . In an emergency use plain wa ­
ter unt il you can get the correct addit ive and can
restore the correct rat io. Th is should be done as
soon as possible.
If you have lost a considerable amount of cool­
ant, then you should add cold antifreeze and cold
water only when the engine is cold.
Always use new engine coo lant when refilling .
Do not fi ll coolant above the "MAX " mark. Excess
coolant will be forced out th rough the pressure
relief valve in the cap when the engine becomes
hot.
A WARNING
- The cooling system is under pressure and can get very hot. Reduce the risk of scalding
from hot coolant by following these steps.
- Turn off the engine and a llow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap s low ly and very ca refully in a

ing devices to alert other motorists.
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the jack,
always fully set the parking brake and block
the wheel diagonally opposite the wheel be­ ing changed with the folding chocks or oth­
er objects . When one front whee l is lifted
off the ground, placing the Automat ic
T ransmission in "P" (Par k) w ill
