Lights and Vision
When switched on, adaptive light adjusts to
curves depending on the vehicle speed and steer­
ing wheel angle. This provides better lighting
through the curve. The system operates in a
speed range from approximately 6 mph (10 km/
h) to 68 mph (110 km/h) .
Static cornering light* -the cornering light
switches on automatically when the steering
wheel is turned at a ce rtain angle at speeds up to
approximately 44 mph (70 km/h) and when the
turn signal is activated at speeds up to approxi­
mately 25 mph (40 km/h) . The area to the side of
the vehicle is illuminated better when turning.
Speed dependent light distribution* -The speed
dependent light distribution adapts the light in
towns and on highways or expressways . Intersec­
tions can also be illuminated on vehicles with a
navigation system* .
Highway light function*
This function adapts the lighting for highway
driving based on vehicle speed .
A WARNING
-Automatic headlights* are only intended to
assist the driver. They do not relieve the
driver of responsibility to check the head­
lights and to turn them on manually accord­
ing to the current light and visibility condi­
tions. For example, fog cannot be detected by the light sensors . So always switch on the
low beam under these weather conditions
and when driving in the dark ~D.
- Accidents could occur if you can not see the road ahead of you well and if others on the
road cannot see you . Always switch your
headlights on so that you can see the road
ahead of you and others can see your vehicle
from behind.
- The rear fog lights should only be turned on
in accordance with traffic regulations, to
prevent glare for traffic behind your vehicle.
-If the battery has been discharging for a
while, the parking light may switch off auto­
matically. Always make sure your vehicle is
parked and adequately lit according to the
44
laws. Avoid using the parking lights for sev­
eral hours.
- Please observe legal regulations when using
the lighting systems described.
(D Tips
- The light sensor for the automatic head­
lights* is in the rearview mirror mount.
Therefore , do not place any stickers in this
area on the windshield.
- Some exterior lighting functions can be ad­
justed
Q page 45.
- If you turn off the ignition while the exterior lights are on and open the door, you will
hear a warning tone.
- In some market-specific versions, the tail
lights do not turn on when switching on the
daytime running lights .
- In cool or damp weather, the inside of the
headlights, turn signals and tail lights can
fog over due to the temperature difference between the inside and outside. They will
clear shortly after switching them on . This
does not affect the service life of the light­
ing.
-A message will appear in the instrument
cluster if there is a malfunction in the light
sensor

A WARNING
Electrolyte fluid can leak from automatic dim­
ming mirrors if the glass is broken. Electro­
lyte fluid can irritate skin, eyes and airways.
48
- Repeated or long-term exposure to electro­
lyte fluid can lead to irritation of the air­
ways, especially in people with asthma or other respiratory conditions. Take deep breaths immediately after leaving the vehi­
cle or, if this is not possible, open all of the
doors and w indows as wide as possible.
-If electrolyte fluid enters the eyes, flush
them thoroughly w ith a large amount of
clean water fo r at least 15 m inutes and then
seek medical attention.
- If electro lyte fluid comes into contact with
the skin, flush the affected area with clean
water for at least 15 minutes and then clean
with soap and water and seek medical at­
tention. Clean affected clothing and shoes
thorough ly before wearing again .
- If the fluid was swallowed and the person is
consc ious, flush the mouth with water for at
least 15 minutes . Do not induce vomiting
unless th is is recommended by medical pro­
fessionals. Seek medical attention immedi­ ately .
CI) Note
If the glass on an automatic dimming mirror
breaks, electro lyte can leak out. This liquid
damages plastic surfaces. C lean this liquid as
quickly as possible with a wet sponge .

Driving
If you anticipate what you need to do next and
drive economically, you can easily cut your fuel
consumption by 10-15 percent. This section will
give you some tips on how you can help the envi­ ronment and your pocketbook.
(D Tips
The consumption estimates as published by ENVIRONMENTAL 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 acceler­
ating.
.. Avoid unnecessary accelerating and braking .
Vehicles 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
erate less. Let the vehicle coast whenever possi ­
ble -for example when you see that the next traf­
fic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage.
.. Try and keep well below your car's maximum
speed .
Accelerating gently reduces fuel consumption,
engine wear, and does not disturb the environ­ ment.
Fuel consumption, exhaust emissions and engine
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 conditions permit.
66
· Reducing unnecessary idling
Even when your car is just idling it burns up fuel .
.. Shut the engine off when you are not driving
the vehicle .
.,. Do not warm up the vehicle by letting the en-
gine run at idle .
It is efficient to switch off the engine when stop­
ped at railroad crossings and long red lights.
Turning the engine off for just 30 -40 seconds
saves more fuel than is burned by starting 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 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 .
@ 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 could result in overheating or
other damage to the vehicle or other proper­
ty.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel.
.. Have your vehicle serviced at regular intervals.
By having your vehicle regularly serviced by an
Audi dealer helps to ensure that it runs properly
and economically. The condition of your vehicle
not only affects its safety and ability to hold its
value, it also affects
fuel consumption.
Check your oil each time you fill your tank.
The amount of oil used is related to engine load
and speed.
It is normal for the oil consumption of a new en­
gine to reach its lowest value after a certain mile -
age has been driven . ..,.

not reached operating temperature yet. You
could damage the engine.
- The engine cannot be started by pushing or
towing.
@) For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately . This re­
duces unnecessary emissions.
(D Tips
- Some noise after starting the engine is nor­
mal and is no cause for concern.
- If the . indicator light blinks in the instru­
ment cluster before switching the ignition
off, the ignition will not switch on again.
¢ page 119
-If you leave your vehicle with the ignition
switched on, the ignition will switch off af­
ter a certain amount of time. Make sure that
electrical equipment such as the exterior lights are switched off.

A WARNING
=
- Never turn off the engine before the vehicle has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use
more force to turn or brake. Because you
cannot steer and brake as you usually
would, this could lead to accidents and seri­
ous injuries.
- Please note that the brake booster and pow­
er steering only work when the engine is
running. When the engine off, you must use
more force to steer or brake the vehicle. Be­
cause the usual steering and braking capa­
bility is not available, the risk of accidents or
injuries increases.
- Always take the vehicle key with you when
leaving the vehicle, even for a short period
of time. This applies particularly when chil­
dren remain in the vehicle. Otherwise the
children could start the engine or operate
electrical equipment such as power win­
dows.
- For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll unintentionally .
- After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes -even with the ignition switched
off.
It can also switch on again after some
time if the coolant temperature rises as the result of heat buildup or if the engine com­
partment is heated by the sun's rays and the
engine is hot.
(D Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off - there is a risk of damaging the
engine. For this reason, let the engine run for
