the type of disp lay in your vehicle. The indica­
tor light
Ill in the instrument cluster also illu­
minates.
The speed is kept constant via an engine out­
put adjustment or active brake intervention.
A WARNING
-Always pay attention to traffic even when
the cruise control is switched on . You are
always responsible for your speed and
the distance between your vehicle and other vehicles.
On the road 85
-For safety reasons, the cruise control
should not be used in the city, in stop­
and-go traffic, on twisting roads and
when road conditions are poor (such as ice, fog, gravel, heavy rain and hydro­
plan ing) - risk of accident .
- Turn off the cruise control temporarily
when enter ing turn lanes, highway exit
lanes or in construction zones.
- Please note that inadvertently ''resting"
your foot on the accelerator pedal causes
the cruise control not to brake. This is
because the cruise control is overridden
by the driver's acceleration .
- If a brake system malfunction such as
overheating occurs when the cr uise con­
trol system is switched on, the braking
function in the system may be switched
off . The other cruise contro l functions re­
main active as long as the indicator light
tij;[i)~1ij (US models) 111 (Canadian mod­
els) is on.
(D Tips
The brake lights illuminate as soon as the brakes decelerate automatically.
Changing speed
.,. Press lever in the 0 or 0 direction
¢ page 85, fig . 84 to increase or decrease
your speed .
.,. Release the lever to save that speed.
Change speed in increments of 1 mph (1 km/ h) by lightly press ing the lever. If you keep the
lever pressed down , you will alter your speed
in 5 mph (10 km/h) increments.
You can also press the accelerator pedal down
to increase your speed, e.g. if you want to
pass someone. The speed you saved earlier
will resume as soon as you release the acceler­
ator pedal.
If, however, you exceed your saved speed by
6 mph (10 km/h) for longer than 5 m inutes,
the cruise control wil l turn off temporarily.

Fig. 112 Front of the vehicle: night vision assistant
camera
The following situations may affect the func­
tion of the night vision assistant system:
- poor v is ibility such as snow, rain, fog or
heavy road spray
- dirty lens on the night vision assistant cam- era
Make sure the n ight v ision assistant camera
i::> fig. 112 is not cove red by stickers, deposits
or any other obstruct ions because that can
prevent the camera from working properly.
F or information on cleaning the lens, refer to
¢page 205.
P edestrian detection depends on the differ­
ence in temperat ure between the person and
the background. Pedestrians may not be de­
tected if the temperature difference is too
small. The pedestrian highlighting feature is
deactivated at temperatures above 77 °F (25
0
() and when it is light outside.

A WARNING
Night vision ass istant has limits and can­
not always detect pedestr ians . Always pay
close attention to traffic and the area
around your vehicle even when night vision
assistant is sw itched on.
- Night vision assistant can only warn
about people located within the visual
range of the infrared camera. The vis ual
range corresponds to the image in t he in ­
strument cluster display.
- Night vision assistant may not detect
peop le and highlight them if
- they are not in an upright posit ion, for
example if they are sitt ing, crouching
or lying down and/or
- if the outline in the display is incom­
plete or interrupted, for example be­
cause the person is part ially hidden by
a parked vehicle .
@ Tips
- Pedestrian detection and the pedestrian
warm ing a re limited to objects that are
detected as pedestrians. The system
does not detect an imals. Even though
the shape and warmth radiated by each
object detected is evaluated, the system
does have limitat ions and it can give in­
correct warnings .
- For technical reasons, the image pauses
in split second intervals.

208 Clea ning and protec tio n
-Never use warm or hot water to remove
snow and ice from windows and mirrors.
This could cause the glass to crack.
- To prevent damage to the wires of the
rear defogger, do not place any adhesive
stickers on the inside of the rear window
over the wires.
- To help prevent d irt from scratch ing the
window, always scrape in a forward d i­
rection - pushing the scraper away from
you - never back and forth .
Cast (light) alloy wheels
Cast (light) alloy wheels require special care.
• Wash the wheels with a sponge or hose
brush every other week.
• For deep cleaning afterwards, use only a
dedicated
acid -free cast alloy wheel cleaner.
• Rub a coat of
liquid wax onto the r ims every
three month . Be sure to reach and treat a ll
parts of the rim.
To preserve the decorat ive appearance of the
cast alloy wheels, some special care is neces­
sary. In addit ion to road dirt and sa lt, b rake
dust is a lso cor ros ive. If left o n for too long,
b rake dust can cause pitting.
Use only special
acid-free cleaners formulated
for a lloy rims. Safe products are available at
your Aud i deale r. Neve r leave the cleaner on
the r ims longer than spec ified on the label.
If
not rinsed off promptly, the acid contained in
some cleaners can attack the threads on the
wheel bolts .
Never use ab ras ive or metal polishing clean ­
ing agents. If the protective coating has been
chipped, e .g. by kicked up road dirt, touch it
up as soon as possible .
A WARNING
- Moisture and ice on brakes may affect
braking efficiency¢
page 189, General

Body cavity sealing
The body cavity sealing does not need to be
checked.
All body cav it ies which could be affected by
cor rosion have been thorough ly protected at
the factory.
T his sealing does not require any inspection or
additional treatment. If any wax shou ld seep
out of the cavity when the ambient tempera­
ture is high, it can be removed with a p lastic
scraper and a suitable solvent.
A WARNING
-Solvents can be dangerous.
- Benzine is flammab le and toxic . If you
use benzine for removing the wax, keep
sparks, flame and lighted cigarettes
away. Never dump benz ine on the
ground, into open streams or down sew­
age dra ins.
- Be sure to observe all safety and environ­
mental regulat ions . Follow all instruc­
tions on the container .
-Always read and heed all WARNINGS and other information ¢

Have the undercoating checked for damage
from time to time.
The lower body shell of your Aud i is also thor­
oughly protected against corros ion.
Any damage to the undercoating ca used by
road hazards should be repaired prompt ly .
A WARNING
-Too much undercoating in the wrong p la-
ces can cause a fire.

vehicle in for service. Yo u are well advised to
replace a battery that is older than 5 years .
W ith certa in types o f airbag deployment, the
battery is disconnec ted from the vehicle elec ­
trica l system for safety reasons

pair, care and disposal of the airbags on
page 156.
Disconn ecting the battery terminal s
Some vehicle functions (power w indow regu­
l ators, for example) are lost if the battery ter­
minals are disconnected . These functions have
to be re learned after the battery terminals are
connec ted again. To prevent this, the battery
should only be disconnected from the vehicle
e lectrical system when absolutely necessary
for repairs .
Vehicles not driven for long period s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cu t back or switched off .
This reduces energy consumption and main ­
tains starting capability over a longer per iod
c::> page 192. Some of the convenience func­
tions may not operate, s uch as the inte rior
lights o r the power sea t adjustment . T he con­
ve nience fun ct ions wi ll be available again
when yo u switch on the ignition and start the
engine.
Winter operation
During the winter mont hs, ba ttery capaci ty
t ends to decrease as tempe rat ures d rop . Th is
is because more powe r is also consumed while
starting , and the headlights, rear window de ­
fogger, etc., are used more oft en.
Avoid unnecessary power cons umption, par­
ticularly in c ity t ra ff ic or when t raveling on ly
short distances. Let your a uthorized Audi
dealer check the capac ity of the vehicle bat ­
tery before winter sets inc::>
page 233. A well
charged battery w ill not only prevent starting
problems whe n the weather is cold, but will
also last longer .
