When switched on, adaptive light adjusts to
curves depending on the vehicle speed and steer­ing 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* (vehicles with adaptive
light) -the cornering light switches on automati­
cally when the steering wheel is turned at acer­
tain angle at speeds up to approximately 44 mph
(70 km/h) and when the turn signal is activated
at speeds up to approximately 25 mph (40 km/
h). The area to the side of the vehicle is illuminat­
ed 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*
(Vehicles with adaptive light or LED headlights) -
This function adapts the lighting for highway
driving based on vehicle speed .
& 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
io.
-Accidents could occur if you cannot see the
road ahead of you well and if others on the
road cannot see you . Always switch your
headlightsonsothatyoucanseetheroad
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 lights may switch off au­
tomatically to conserve the battery charge
Lights and Vision
for the next time the engine is started. Al·
ways make sure your vehicle complies with
legal regulations regarding sufficient and
safe lighting when parking it. Avoid using
the parking lights for several hours.
- Please observe legal regulations when using
the lighting systems described .
@ 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 functions of the exterior lighting can
be adjusted
¢ page 48 .
-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

outlet, regardless of whether it is protected
against a short circuit or not.
- Always disconnect the connector cable and
close the cover
(D before starting the engine.
.&_ WARNING
Using the engine preheater incorrectly can
cause short circuits, electric shocks, fire, seri­
ous injuries and death.
- The connector cable must always be con­
nected to a grounded 120 Volt socket that
is equipped with a GFI circuit breaker . Al­
ways protect the sockets from water, mois ­
ture and other fluids .
- Never plug the engine preheater into a con­
ventional outlet, regardless of whether it is protected against a short circuit or not .
.&_ WARNING
-
Short circuiting, fire, serious injuries and life­
threatening or lethal electric shock can result
from using unsuitable or damaged sockets and connector cables/extension cords, using
electrical equipment incorrectly, and/or disre­
garding general safety precautions.
- Always plug the extension cord into a 120 V
socket that is properly functioning, ground­
ed, equipped with a GFI circuit breaker and
is protected against water, moisture and
other fluids.
- Never connect the engine preheater to a
conventional socket, even if the socket is
protected by a fuse.
- Always check the fuse on the 120 Volt GFI
socket before connecting the connector ca­
ble to the engine preheater on the vehicle.
- Only use highly durable extension cords that
are class 12 or better and can be properly grounded to a three-prong wall socket with
a GFI circuit breaker . The extension cord
must not be longer than 100 feet (30 me­
ters).
- Never use damaged connector cables, ex­
tension cords or sockets . Always check the
connector cable, extension cord and sockets
for damage before using them. Damaged
parts must be replaced. If damaged, replace
76
the engine preheater connector cable at an
authorized Audi dealer or authorized Audi
service facility .
- Only use the connector cable provided to
connect the vehicle socket to a suitable
power source. Use a suitable extension cord
if necessary .
- Always disconnect the connector cable from
the vehicle socket before starting the en­
gine. Switch off the power supply to the
connector cable and to the extension cord if necessary, or disconnect the cable or exten­
sion cord from the 120 Volt socket equip­
ped with a GFI circuit breaker. Never leave
the connector cable or extension cord con­
nected to a live power source.
- Never make alterations or repairs to the
connector cables or extension cords that
supply power to the engine preheater or to
any components that affect the engine pre­
heater.
- Always protect the connections from water,
moisture and other fluids. Always store the
connector cable and extension cord securely
and in a dry place when they are not being
used, and disconnect them from the power
source before storing .
(D Tips
Test the GFI circuit breaker once a month if
you use the engine preheater occasionally, and test it weekly if you use it regularly.

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.
78
· 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 . ..,.

Driving
- Hill Hold cannot hold the vehicle in all h ill
start situations (for example, if the ground
is slippery or icy).
- If you do not begin moving immediate ly af­
ter releasing the brake pedal, the vehicle
could beg in to roll backward under certain
c ir cumstances . Press the brake pedal or set
the parking brake immediately.
- If the engine "sta lls", press the brake pedal
o r set the parking brake immediately.
- Stop-and-go traff ic on incl ines: to help pre­
vent the veh icle from rolling back when con ­
t inuing to drive, p ress and hold the brake
pedal for several seconds when the vehicle
is stationary.
