In veh icles with all-weather lights, the front
lights are adjusted automatically so that yo u are
less likely to see glare from your own headlights,
for example when driving on a wet road .
Headlight range control system
The headlight range adjusts automatically when
there is a change in vehicle load a nd during brak­
ing and accelerating so that the headlights do
not cause glare for oncoming traff ic.
Audi adaptive light*
T he adaptive light only wo rks when the light
switch is in the AUTO position . You can deactiva te

Light 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* (vehicles with adaptive
light)· the cornering light switches on automati­
cally when the steering wheel is turned at acer­
tain ang le at speeds up to approximately 44 mph
(70 km/h) and whe n 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 tu rning.
Speed depend ent light distribution* -The speed
dependent light distribution adapts the light in
towns and on highways or expressways. In tersec­
tions can also be illum inated on veh icles with a
navigat ion system*.
Highway light function*
(Vehicles with adaptive light or LED headlights) -
This function adapts the light ing for highway
driving based on vehicle speed .
..&, WARNING
-Automatic headlights* are only int ended to
assist the driver. They do not relieve the
driver of his responsibility to check the
headlights and to turn them on manually
according to the current light and visibi lity
condit ions. For example, fog cannot be de·
tected by the light sensors . So always switch
on the low beam under these weather con­
ditions and when driving in the dark
io.
- 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
head lightsonsothatyoucanseetheroad
ahead of you and others can see your vehicle
from behind.
- Please observe legal regulations when using
the lighting systems described .
44
(D Note
The rear fog lights shou ld only be turned on in
accordance with traffic regulation, as the lights are bright for following traffic.
@ 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
c> page 45.
- If you turn off the ignition whi le 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 taillights 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 serv ice life of the light­
ing .
- A message will appear in the instrument
cluster if there is a malfunction in the light
sensor

Assist
Assist Electronic speed limiter*
Applies to veh icles: with electronic speed limiter
Your vehicle may be factory equipped with ti res
that are rated for a maximum speed of 130 mph
(210 km/h) . T his is less than the maximum speed
of your vehicle . To reduce the risk of sudden tire
failure and loss of control if the vehicle is operat­
ed at excessive speeds, your vehicle also has an
electronic speed limiter. The electronic speed
limiter prevents your vehicle from going faster
than the tir e speed rat ing . For more information
~page 221.
If the engine control unit receives faulty vehicle
road speed signals, the Malfunction Indicator
Lamp (MIL)
¢4 will illuminate . If this occurs,
contact the nearest a utho rized Audi dealer for as­
sistance .
A WARNING
Always observe the posted speed limits and
adjust your speed to suit prevailing road, traf­
fic and weather conditions . Never drive your
vehicle faster than the maximum speed rating of the tires installed.
Speed warning system
Introduction
The speed warning system helps you to stay un­
der a specified maximum speed.
-
The speed warning system warns you if you are
exceeding the maximum speed that you have set .
You will hear a warning tone when your speed ex­
ceeds the stored value by approximately 3 mph
(3 km/h) . Th e. (USA models)/. (Canada
models) indicator light and the message
Speed
limit exceeded!
appear in the instrument cluster
disp lay at the same time . The ./. indicator
light turns off when the speed decreases below
the stored maximum speed.
Setting a thresho ld is recommended if you would
like to be reminded when you re ach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener-
94
al speed limit or if there is a specified maximum
speed for winter tires.
(D Tips
Regardless of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are following
the legal speed limit .
Setting the threshold
You can set, change and delete the threshold in
the MMI.
.. Select: the I MENU I button >Car> Systems*
contro l button > Driver assistance > Speed
warning.
You can set any threshold between 20 mph
(30 km/h) and 150 mph (240 km/h) . Settings
can each be adjusted in increments of 6 mph
(10 km/h).
Cruise control system
· Description
Applies to vehicles: with cruise control system
The cruise control system makes it poss ible to
drive at a constant speed starting at 15 mph
(20 km/h).
The speed is kept constant by modify ing engine
power or through an act ive brake intervention.
A WARNING
- Always pay attention to the traffic around
you when the cruise control is in operation.
You are a lways responsible for your speed
and the distance between your vehicle and
other vehicles.
- For reasons of safety, cruise contro l should
not be used in the city, in stop-and-go traf­
fic, on winding roads and when road condi­ tions are poor (such as ice, fog, gravel,
heavy rain and hydroplaning) -you could
have an accident .
- Switch the cruise control off temporarily
when driv ing in turning lanes, highway exits
or in construction zones .

-For safety reasons, act ive lane assist must
not be used when there are poor road and/
or weather conditions such as slippery

Checking and F ill in g
sure you are using the correct brake f luid .
The correct type of brake fluid is also indi­
cated on the brake fluid reservoir .
- The brake fluid must be new. Heavy use of
the brakes can cause a vapor lock if the
brake fluid is left in the system too long.
This can ser iously affect the effic iency of
the brakes as well as your safety . This
could res ult in an accident.
(D Note
Brake flu id will damage the paint of your vehi­
cle .
@ For the sake of the environment
Because of the problem of proper d isposa l of
brake fluid as well as the spec ia l tools re-
quired and the necessary expertise, we rec ­
ommend tha t you have the b rake fluid
changed by your author ized Audi dealer.
Battery
General information
The battery in yo ur Audi does not need any ma in­
tenance under normal operating conditions. Aud i
recommends having the electro lyte level check by
an author ized Audi dealer or author ized Audi
Service Fac ility when the re a re
high outside tem­
pe ratu res or when dr iv ing a ll day. The electroly te
leve l sho uld also be checked ea ch t ime the bat ­
t ery is charged
9 page 210 .
Have the battery checked when you br ing you r ve­
hicle in fo r an inspec tio n. It is a good idea to re­
p la ce the batte ry if i t is more than 5 ye ars old .
During certai n types of a irbag dep loyments, the
battery is disconnect ed from the vehicle electr i­
cal system fo r safety reasons
9 .&. in Repair, care
and disposal of the airbags on page 163.
Disconnecting the battery terminals
Some veh icle functions (such as power windows)
are not ava ilable when the batte ry is disco nnect­
ed. These functions must be programmed after
the ba ttery is reconnec ted. To avoid havi ng to do
t his , on ly disconnect the b attery from the veh icle
208

form repairs.

Winter operation Du ring the winter months , it is common for the
batte ry capaci ty to dec rease as the tempe rat ur es
become lower . This is because more powe r is
needed to start the vehicle and componen ts such
as the he ad lights and the rear window defogger
are used more frequent ly.
