& 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. •
Applie s to v ehi cles: with he adli gh t wash er syst em
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. •

What impairs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted.
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety risks for everybody in the vehicle increase and you also
Controls and equip­ ment Safety first Vehicle operation
become a
hazard to everyone else on the road =>&, .There ­
fore:
- Do not let yourself be distracted by passengers or by
using a cellular telephone.
- NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc .).
- Observe all traffic laws, rules of the road and speed limits
and plain common sense.
- ALWAYS adjust your speed to road, traffic and weather
conditions.
- Take frequent breaks on long trips. Do not drive for more
than two hours at a stretch.
- Do NOT drive when you are tired, under pressure or when
you are stressed.

For example, in a frontal co llision at a speed of 30 mph (48 km/h),
the forces acting on a 10 -lb ( 4.5 kg) object are about 20 times the
normal weight of the item. This means that the weight of t he item
would suddenly be about 2 00 lbs. (90 kg). You can imagine the inju ­

serious personal injury .
• Always use suitable mounting straps and properly secure
items to the tie -downs in the luggage compartment to help
prevent items from shifting or flying forward as dangerous
missiles .
• When the rear seat backrest is folded down , always use suit ­
able mounting straps and properly secure items to the tie -downs
in the luggage compartment to help prevent items from flying

• Never attach a child safety seat tether strap to a tie -down. •
Reporting Safety Defects
Applicable to U.S.A. If you believe that your vehicle has a defect
which could cause a crash or could cause injury or death , you should immediately inform
the National Highway Traffic Safety Adminis­
tration (NHTSA) in addition to notifying Audi of
America , Inc.
If NHTSA receives similar complaints , it may
open an investigation, and if it finds that a
safety defects exists in a group of vehicles , it
may order a recall and remedy campaign.

Electronic differential lock (EOL)
The electronic differential lock monitors the rotational
speed of the drive wheels.
General notes
The electronic differential lock (EDU helps the car to start moving,
accelerate and climb a gradient on surfaces providing poor or
almost no grip. Without EDL, this would be difficult, if not impos ­
sible.
How the system works
Th e EDL operates automatically. It monitors the rotational speed of
the drive wheels on an axle with the help of the ABS sensors
=> page 187. If a noticeable difference in rotational speed between
the drive wheels on one axle is detected (e.g. on slippery ground on
one side), the spinning wheel is braked, thereby transferring power
to the other drive wheel or wheels (all-wheel drivel. This is done up
to a speed of about 60 mph (100 km/hl. Noises from the brake
system signal that wheel spin is being controlled.
Driving off
When driving off, always be sure to keep road conditions in mind as
you accelerate . If one drive wheel spins because it is on a surface
with less grip, gradually increase the pressure on the accelerator
pedal until the car starts to move. The wheel less able to transfer
power spins.
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads, the EDL cuts out temporarily . The
vehicle remains operational and behaves in the same way as a
vehicle without EDL.
As soon as the brake has cooled down, EDL switches on again auto­
matically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL working, 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 risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
If a fault occurs in the ABS, the EDL is also not functioning . This is
indicated by the ABS warning light=> page 20. •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Slip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP). When the vehicle starts up and acceler ­
ates , the wheels are prevented from spinning by adjusting the
engine power to match the amount of grip available from the road
surface .
How the system works
ASR performs automatically, i.e. without the driver's intervention .
With the aid of the ABS sensors => page
187, ASR monitors the
speed of the driven wheels. If the wheels start to spin, the engine
torque is reduced automatically until the tires find enough grip to
lock onto the road surface . The system is active across the entire
speed range.
The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action .
