Driv ing off
When driving off, always be sure to keep road conditions in mind as
you acce lerate. If one d rive w heel spins because it is on a surface with
less grip, gradua lly inc rease the press ure on the accelerator pedal
un til the car sta rts to move .
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads o n this whee l, t he EDL cuts out tem po­
ra rily. The vehicle rema ins operat iona l a nd be haves in the same way
as a ve hicle wit hout EDL.
As soon as the bra ke has coo le d down , ED L swit ches on again au to­
matically.
& WARNING
• When accelerating on slippery surfaces , such as on i ce or snow ,
alway s be careful when depre ssing the accelerator pedal. Even
with the EDL work ing , the drive wheels can spin and reduce your
ability to control your car. Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety ri sks . Always adapt your driving style to the road
conditions and traffic situation.
(I) Tips
If a fa ult occurs i n the ABS, the EDL is also not f unct io ni ng . This is
indic ated by t he A BS war ning ligh t=>
page 17.
Anti-Slip Regulation System (ASR)
The Anti- S lip Re gula tio n Sy stem preven ts the dr iven
w heels from spin ning w hen t he car is accelerating .
General notes
The Anti-S lip Reg ulation Sys tem (AS R) is in tegr ate d in the ele ctroni c
stabilization program (ESP) . When the ve hicle starts up and acceler­
at es, the whee ls are p reven ted from sp inning by adjust ing t he engine
power to match the amount of grip avai lable from the road surface.
How the system works
ASR performs automatically, i.e. witho ut the driver 's intervent ion.
W ith the a id of t he ABS sensors=>
page 244, ASR moni to rs the speed
of the dr iven wheels. If the wheels start to spin , th e engine torque is
redu ced a utomatically unti l the t ires find enou gh gr ip to lock onto
the road surface. T he system is active across the entire speed range .
Th e ASR works in conjunction with the ABS. If a malfunction sho uld
occ ur in th e ABS, th e AS R w ill also be out of action.
Activating
The ESP is automatically activated whe n the engine is started and it
performs a se lf-test. You can act ivate a deact ivate d ASR if required by
press ing the=>
pag e 240, fig. 201 button. Whe n it is act ivated, t he
message
ESP/ASR on appears briefly in t he disp lay. Vehicles with
front-wheel d rive a dea ct iva te d ASR a uto mat icall y re-ac tiva tes i tself
at a speed of 40 mp h (70 km/h) .
Deactivating
You can deact ivate t he ASR if required by pressing t he button (for less
t han 3 se conds) =>
page 240, fig. 2 0 1. Wi th the ASR dea ct ivated, the
ESP check light comes on, see=>
page 14. The message ASR off
appe ars i n the di sp la y as wel l. On vehicles wi th fro nt-whee l dr ive:
deactivation is possible only up to 30 mph (SO km/h) for safety
reas ons. Vehi cles w ith all -w heel drive: the AS R can be deac tivated at
any speed. ..

How the ABS system works
An au tom ati c c heck is m ade w hen a speed of about 4 mp h (6 km /h) is
reac hed. When th is happens, a pump ing no ise can be heard.
If an indivi dual w heel beg ins to rot ate too s low ly in relat ion to vehi cle
speed and tends to lock, t he A BS a utomat ically reduces brake pres­
sure to prevent that w heel from loc king .
Thi s au tom atic adju stm ent pr oces s w ill c au se a
slight vibration of
the brake pedal and some noises to alert you that vehicle speed must
be ad apted to exis tin g road and traff ic c ondi tio ns.
& WARNING
Although the ABS is very effective, always remember that braking
capability is limited by tire traction. Always adjust your driving
speed according to the road and traffic conditions. Do not let the
extra safety afforded by the ABS tempt you into taking extra risks.
The ABS cannot overcome the laws of physics.

Intelligent technology
'-------------------------------------------------
It is in precisely these situations that you will notice energy manage­
ment actively regulating the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period of several days or weeks,
electrical components are gradually cut back or switched off. This
red uces energy consumption and maintains starting capability over a
longer period.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the remote key or power seat adjust­
ment, may not be avai lab le. The convenience functions wi ll be ava il­
able again when you turn on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for example, with the engine turned off o r
use other MMI functions, the battery is being discharged.
If starting capability is jeopard ized due to energy consumption, the
following warning appears in the MMI display:
Please start engine, otherwise system will switch off in
3 minutes .
The warning indicates that the system will be turned off automati­
cally after 3 minutes. If you wis h to continue using the funct ions, you
have to start the engine.
With the engine running
Although electrica l energy is generated when the vehicle is being
dr iven, the battery can become 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 equilibrium, consumers which
req uire especially large amounts of energy are temporarily cut back
or switched off . H eating systems in particular 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 ava ilable again as soon as
the energy ba lance 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 addit ional energy required is generated and the
battery is charged. •
Driver notification in the instrument
cluster display
If battery powe r drops into the range where it can limit the ability of
the engine to start, this is shown in the instrument cluster display
w ith the following driver message:
1 Low battery charge: battery will be charged while driving
This notification reminds you that the starting capability of the
eng ine may be limited. As soon as you start driving again, the battery
will be recharged and the notification will go out.
Driver notification appears and goes out again
If this driver notification appears after the ignition is turned on or
wh ile driving and it goes out again after a while, the battery has been
adequately recharged.
Driver notification appears and does not go out
again
If this dr iver not ificat ion appears after the ign it ion is turned on or
whi le driving and does not go out again, the battery's state of charge
is not in the optimal range. Starting ability is restricted . Have the
battery checked as soon as possible at a dealership.

Driving and environment
(I] Tip s
The consumption estimates as pub lished by ENV IRONMENTAL
PROTECTION AGENCY (EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary
depending upon vehicle load and speed, road and weather conditions,
trip length, etc. •
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are accelerating .
-Avo id unnecessary accelerating and braking.
Vehicles use the most fue l when they a re accele rating. 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
example when you see that the next traffic l ight is red. •
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
- Try and keep well below your car's maximum speed .
Accelerating 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 approx imately three
qua rters of top speed, fuel consumption will be reduced by one half.
Never drive faster than the posted speed limit and weather condi­
tions permit.
a Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
-
Shut the engine off when yo u are not driving the vehicle.
- Do not warm up the vehic le 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, o r at traffic lights that have long
wa its on red . Turn ing the eng ine off for just 30-40 seconds saves
more fuel than is burned starting the engine again.
It takes a long t ime for the engine to warm up fully when it is running
at idle. Howeve r, wear and noxious emissions are espec ially high
when the eng ine is wa rm ing up. So you sho uld d rive away as soon as
you start the engine and avoid running at hig h rpms while the eng ine
is still warming 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 idling also produces heat, which cou ld result in
overheat ing o r othe r damage to the vehicle or other p roperty. •
Regular maintenanc_e ____________ _
A badly tuned engine unnecessarily wastes a lot of fuel .
- Have your vehicle serviced at regular intervals .
By having yo ur vehicle regularly se rviced by an Audi dealer helps to
ensure that it runs properly and economically . T he condition of your
vehicle not only a ffects its safety and ability to ho ld its va lue, it a lso
affects
fu el con sumption .
Check your o il e ach tim e you fill you r tank.

Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passenger transpor ­
tation .
If you p lan to tow a t railer, p lease remember that the additional load
w ill affect durability, economy and performance.
Tr ailer towing not on ly p laces mo re s tress on the vehicle, it also calls
for more concentration from the driver.
For this reason, a lways follow the operating and dr iv ing inst ructions
prov ided and use common sense .
0 Note
If you are going to tow a trailer, you must activate the tra iler ope ra­
tion mode =>
page 168, "Towing a tra iler". •
Technical requirements
Trailer hitch
Use a we igh t-car rying h itch co nform ing to the gross tra iler we ig ht.
The h itch must be suitab le for your vehicle and trailer and must be
mou nted securely o n th e vehi cle's ch assi s at a
techni cally sound loc a­
tion . Use only a trailer hitch with a removab le ball mount. Always
check wit h the t railer h itch manufactu rer to make sure that yo u are
using the correct h itch .
Do not use a bumper hitch.
The h itch mus t be installed in such a way t hat it does not in terfe re
w ith t he impact-absorb ing bumper system. No modifications shou ld be made to t
he veh icle exha ust and bra ke systems. From t ime to
time, check that a ll hitch mounting bo lts rema in securely fastened.
W hen you are no t tow in g a tra ile r, remove the t railer hit ch ball
mount. This prevents the hitc h from caus ing damage should your
vehicle be str uck from behind=>& .
Trailer brakes
If your trail er is e quipped w ith a b raking system, che ck to be s ure t hat
it conforms to all regulations.
T he tra ile r hydrau lic brake system m ust not be directly connected to
t he vehicle's hyd raulic b rake sys tem .
Safety chains
Always use safety chains between your veh icle and t he tra ile r.
Trailer lights
Trailer lights must meet all regulations. Be sure to check w ith your
Audi de aler fo r corr ec t wir ing , sw itches and re lays.
Mirrors
If you are unab le to see t he t raff ic be hind you using t he regular
outs ide mirrors, then you
must install extended mi rrors. It is impor­
t an t th at yo u
always ha ve clear vi sion to the re ar.
& WARNING
After removing the trailer hitch, do not store it in your vehicle. In
case of sudden braking , the hitch could fly forward and inju re you
or your passengers. •

Trailer towing
"---------------------------------------------------
Speed
T he higher the speed, the more difficult it becomes for the driver to
control the rig. Do not dr ive at the max imum permiss ible speed.
Reduce your speed even more if load, weather or wind conditions are
unfavorable -part icu larly when go ing downhill.
Reduce vehicle speed
immediately if the tra iler shows the slightest
sign of swaying.
Do not try to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for veh icles towing
trailers are lower than for regu lar vehicles.
Always apply brakes early. When driv ing dow nhill, shift in to a lower
gear to use the eng ine braking effect to slow the veh icle. Use of the
bra kes alone can cause them to overheat and fail.
Coolant temperature
Th e coolant temperature gauge~ page 8 must be observed care­
fully. If the needle moves close to the upper end of the scale, reduce
speed immediately and/or turn off the air conditioner.
If the coolant temperature warning light in the instrument cluster
starts flashing
_f_ , pull off the road, stop and let the engine idle for
about two m inutes to prevent heat build-up.
& WARNING
Anyone not properly restrained in a moving vehicle is at a much
greater risk in an accident. Never let anyone ride in your car who is
not properly wearing the restraints provided by Audi.•
Trailer towing tips
Important to know
------------
Your vehicle handles differently when tow ing a trailer because of the
additiona l weight and different weight distribution. Safety, perfor- mance and economy will greatly depend on how carefully you load
your trailer and operate your rig.
Before you actually tow your trailer, practice turning, stopp ing and
backing up in an area away from traffic. Keep practicing until you have
become completely familiar with the way your vehicle-t railer comb i­
nation behaves and responds.
Backing up is difficult and requires practice. Backing up with a trailer
generally requires steering action oppos ite to that when backing up
your vehicle without a trai ler.
Maintain a greater distance between your vehicle and the one in front
of you. You will need more room to stop. To compensate for the
trailer, you will need a larger than normal turning radius .
When passing, remember that you cannot accelerate as fast as you normally would because of the added load . Make sure you have
enoug h room to pass. After passing, allow plenty of room for your
trai ler before changing lanes again.
Avoid jerky sta rts, sharp tur ns or rapid lane changes.
W Tips
• Do not tow a trailer during the break-in per iod of your veh icle.
• If you tow a trai ler, your Audi may require more frequent mainte­
nance due to the extra load
~ page 344. •
Parking on a slope
Do not park on a slope with a trailer. If it cannot be
avoided, do so only after doing the following:
When parking:
- Apply the foot brake.
- Have someone p lace chocks under both the vehicle and the
trailer wheels . ._

0 Note
• Never try to remove dirt, mud or dust if the surface of the vehicle
is dry. Never use a dry cloth or sponge, since this could scratch your
vehicle's paint or windows.
• Never wash your car in bright sunlight . Drops of water act as
magnifying lenses and may damage your pa int.
• When you wash your car in the winter: if you rinse your vehicle with
a hose, be careful not to a im the stream of water d irectly at locks, or
at door or hatch openings -they can freeze shut.
• Never use sponges designed to remove insects, or any kitchen
scouring sponges or similar products. They can damage your paint
fin ish .
• Never use a dry cloth or sponge to clean the headlights . Only use
wet cloths or sponges to prevent scratches . It is best to use soapy
water.
For the sake of the environment
In the interest of the environment, the vehicle should on ly be washed
in special wash bays. •
Washing your vehicle with a power washer
Cleaning the exterior of your car with a high-pressure
power washer is safe as long as you observe a few simple
rules .
-Before using the power washer, make sure you have read
and unders tood the WARNINGS ~
& in "General infor­
mation" on
page 258.
- Always follow the operating instructions for the power
washer. -
Make sure that the jet on the spray hose produces a "fan
shaped spray".
- Do
not hold the spray nozzle too close to soft materials.
When cleaning the vehicle with a power washer always follow the
operating instructions. This applies particularly to the
operating
pressure
and the spraying distance. Maintain a sufficient distance to
soft materials such as rubber hoses and sound/vibration deadening
materials (particularly on the underside of the engine hood). Do not
use a jet which sprays water in a
direct stream or one that has a
rotating jet.
Water temperature should not exceed 140
°F (60 °() .
& WARNING
Never wash tires with a jet that sprays water in a direct stream.
This could cause invisible damage to the tires and weaken them,
even if the spray is from a relatively long distance and for a short
time. Damaged and weakened tires can fail and cause accidents
and personal injury .
0 Note
To avoid damaging your vehicle, always make sure that there is suffi­
cient distance between the spray head and soft materials like rubber
hoses , plastic parts and sound-deadening mater ials. Never aim the
spray head at the same point for a long time. This a lso applies to
cleaning headlights and painted bumpers. Remember: the closer the
nozzle is to the surface of the material, the greater the stress on the
material. •
