& WARNING
• Wiper blades are crucial for safe driving! Only when they are in
good condition are they able to clear the windows properly to
provide uncompromising visibility. Worn or damaged wiper blades
are a safety hazard~
page 63, "Replacing front wiper blades"!
• The light/rain sensor* is only designed to assist and support
the driver. It remains entirely the driver's responsibility to monitor outside weather conditions and to manually activate the wipers as
soon as rain or drizzle reduces visibility through the windshield.
• The windshield must not be treated with water-repellent mate­
rials. They can increase glare under poor visibility conditions such
as wetness, darkness, or when the sun is low on the horizon. In
addition, they can cause the windshield wipers to chatter.
0 Note
In freezing or near freezing conditions:
• Always check that the wiper blades are not frozen to the glass
before you turn the wipers on. Loosen a wiper blade which is frozen
in place before operating the wipers to prevent damage to the wiper
blade or the wiper motor.
• Do not use the wipers to clear a frosted window . Using the
wipers as a convenient ice scraper will destroy the wiper blades.
• Before you take your vehicle to an automatic car wash, make sure
you have the windshield wiper system switched off (lever in position
0), otherwise the windshield wiper system could get damaged in the
car wash if it should suddenly come on.
[ i] Tips
• The rain sensor is part of the interval wiping system. Turning off
the ignition will also deactivate the rain sensor . To reactivate the
sensor, switch off the interval wiping function, then switch it back
on again.
Controls and equip ­
ment
Clear vision
• Worn or dirty windshield wiper blades cause smearing, which
can affect the operation of the light/rain sensor*. Check the condi­
tion of your windshield wiper blades regularly.
• Applies to vehicles with light/rain sensor: When the wipers are
switched on manually and in rain conditions, the automatic head­
lights* turn on~
page 52, "Sensor activated head and tail light
control" or off during the day when the wipers are no longer oper­
ating. The automatic headlights * function is available in this case
only when the light switch is in the "AUTO" position~
page 52,
fig. 40.
• Make sure the washer fluid reservoir in the engine compartment
is topped off before going on a long trip. Look up~
page 233 for
checking and filling the washer container .
• The wipers only operate with the hood completely closed. •

Headlight washer system
The headlight washer system cleans the headlights.
Operate the windshield wiper/washer system=> page 60,
fig. 50 ® with the headlights turned on by holding the
lever for longer than one second.
The washer jets extend forward out of the front bumper driven by
water pressure to spray the front headlights with water .
You should inspect the headlights regularly (for example when refu ­
eling) and clean off any solid dirt or insects from the lenses.
To ensure the system works properly in winter, keep the washer jets
free of snow and remove any ice using a de -icing spray. •

Activating
The ESP is automatically activated when the engine is started and it
performs a self-test. You can activate a deactivated ASR if required
by pressing the=>
page 182, fig. 130 button. When it is activated,
the message
ESP/ASR on appears briefly in the display. Vehicles
with front -wheel drive a deactivated ASR automatically re -activates
itself at a speed of 40 mph (70 km/h).
Deactivating
You can deactivate the ASR if required by pressing the button (for
less than 3 seconds)=>
page 182, fig. 130. With the ASR deactivated,
the ESP check light comes on, see=>
page 17. The message ASR off
appears in the display as well. On vehicles with front -wheel drive:
deactivation is possible only up to 30 mph (50 km/h) for safety
reasons. Vehicles with all -wheel drive : the ASR can be deactivated
at any speed.
The ASR should normally be activated all the time. Only in certain exceptional situations when some slip 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 J Tips
To ensure that the ASR works properly, all four wheels must be fitted
with identical tires. Any differences in rolling radius of the tires can

• Automatic deployment : At a speed of about 75 mph (120 km/h),
the rear spoiler deploys automatically.
• Automatic retraction: When speed drops below about 50 mph
(80 km/h), the rear spoiler retracts automatically.
Manual mode
• Manual deployment: Tapping briefly on the switch ::::> fig. 131
deploys the rear spoiler .
• Manual retraction: At speeds up to about 10 mph (20 km/h),
retract the rear spoiler by pressing and holding the switch
::::> fig. 131. At speeds between 10 mph (20 km/h) and 75 mph (120

Vehicle care I I irechnical data

• Be aware of the different than usual steering response and
adjust your steering force accordingly.
• Have the problem checked and set right by an authorized Audi
dealer as soon as possible.
• If a steering malfunction occurs, this is signaled with the or.
~ indicator lights and a warning tone, see.
[ i] Tips
• If the power steering system should fail, or if the engine is not
running (for example, while being towed} , you will still be able to
steer the vehicle. However, more effort will be required to do so.
• If the power steering system is not functioning properly, contact
your authorized Audi dealer immediately.
Ap plies to vehicles : w ith A ll Wheel Drive
0 iving w i h your quattro®
With All Wheel Drive, all four wheels are driven.
General information
With All Wheel Drive, power is distributed to all four wheels. This
happens automatically depending on your driving style and the
road conditions at the time. See also=> page
184, "Electronic differ ­
ential lock (EDU".
Winter tires
When driving in the winter , your vehicle with All Wheel Drive has an
advantage, even with regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-season tires} for improved
driveability and braking : these tires must be mounted on all four
wheels. See also=> page 250, "Winter tires".

Snow
chains
Where tire chains are mandatory on certain roads, this normally
also applies to vehicles with All Wheel Drive=> page 251, "Snow

Replacing wheels/tires
Vehicles with All Wheel Drive must always have tires of the same
size. Also avoid tires with different tread depths . For details see
page => page 246, "New tires and replacing tires and wheels".
Off-Road driving?
Your Audi does not have enough ground clearance to be used as an
off-road vehicle. It is therefore best to avoid rough tracks and
uneven terrain as much as possible. Also refer to=> page 192.
& WARNING
Always adjust your driving to road and traffic conditions. Do not
let the extra safety afforded by All Wheel Drive tempt you into
taking extra risks.
• Although the All Wheel Drive is very effective, always
remember that braking capacity is limited by tire traction. You
should therefore not drive at excessive speeds on icy or slippery
road surfaces.
• On wet road surfaces, be careful not to drive too fast because
the front wheels could begin to slide on top of the water (aqua­ planing}.
If this should occur, you will have no warning from a
sudden increase in engine speed as with a front-wheel drive
vehicle . Always drive at speeds which are suited to the road condi­
tions. -risk of crash. •

Reducing unnecessary Idling
Even when your car is just idling it burns up fuel.
- Shut the eng ine off when you are not driving the vehicle .
- Do not warm up the vehicle by letting the eng ine run at
idle.
I t makes sense to shut off the engine in traffic jams, when waiting
for trains to pass at railroad crossings, or at traffic lights that have long waits on red. Turning the engine off for just 30 -40 seconds
saves more fue l than is burned s tarting 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 a re especial ly
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 whi le
the engine is stil l 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 idl ing also produces heat, wh ich cou ld
result in overheating or other damage to the vehicle or other
property .•

Good anti-corrosion treatment is very important, particularly in the
winter. If the vehicle is frequently driven on salt treated roads, the
entire engine compartment and plenum panel should be thor ­
oughly cleaned at the end of winter and retreated to prevent salt
damage. At the same time, the underside of the vehicle should be
washed as well.
