On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Ma lfunction Indicator Lamp (MI L) ¢,ij in the
inst rument cluster is part of the On-Boa rd Diag­
nostic (OBD II) system .
T he wa rning/indicator light ill uminates when the
ignition is sw itched on and goes out after the en­
gine starts and the idle has stabilized. This indi­
cates that the MIL is working properly.
If the li ght do es not go out after the eng ine is
sta rted, or i lluminates while you are driving, a
malfunction may exist in the engine system. If
the lig ht illuminates, the catalytic converter
could be damaged.
Cont inue driving
with reduced power (avoiding
s ustained high speeds and/o r rapid accelera­
tions) and have the condit ion corrected. Contact
your authori zed Aud i dea ler .
If the light i llum inates, the elect ronic speed lim­
iter may also be malf unct ion ing. For more infor­
mation

detected by the light sensors. So always
switch on the headlights gD under these
weather conditions and when driving in the
dark .
- Crashes can happen when you cannot see
the road ahead and when you cannot be
seen by other motorists . Always turn on the
headlights so that you can see ahead and so
that others can see your car from the back.
- The rear fog lights should only be turned on in accordance with traffic regulation, as the
lights are bright for following traffic.
- Please observe legal regulations when using
the lighting systems described .
(D Tips
-The light sensor* for automatic dynamic
headlight range control* is located in the
rear view mirror mount . You should there­
fore not apply any stickers to the windshield
in this area in order to prevent malfunctions
or failures .
- In the event of a light sensor malfunction,
the driver is notified in the instrument clus­
ter display~
page 25.
- You will hear a warning tone if you open the
driver door when the exterior lights are
switched on.
- 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 WARNING
- The rain sensor is only intended to assist the

for manually sw itching the wipers on based
on v is ibility conditions .
- The w indshield may not be treated with wa­
ter-repelling windsh ield coating agents . Un­
favorable conditions, such as wetness, dark­ ness, and when the sun is low, can cause in­
creased g lare, which increases the risk of an
acc ident. W iper blade chatter is a lso poss i­
ble.
- Prope rly f unction ing windsh ield wiper
blades are required fo r a clear view and safe
driving

blades.
(D Note
- If there is frost, make su re t he windshie ld
wiper blades are not fro zen to the wind­
shield. Sw itching on the windshield wipers
when the blades are frozen to the wind­
shield can damage the wiper blades.
- Prior to using a car wash, the windshield
wiper system must be switched
off (lever in
pos ition
@ ). This prevents the wipers from
switching on un intent ionally and causing
damage to the w indshield w iper system .
- The windshield wipers switch
off when the

windsh ield wipers after the ign it ion is
switched back on by moving the winds hield
wiper lever to any posit ion.
- Worn o r dirty windshield wiper blades result

Marking light*
To direct the driver's attention to a pedestrian,
the headlights can flash on the pedestrian three
times in a row when there is a pedestrian warn­
ing.
This occurs at speeds above approximately 35 mph (60 km/h) if you are outside of illuminat­
ed areas and no detected vehicles are shown. The
high beam assistant* controls the marking light*

The marking light is not used for wild animals.
General information
Applies to: vehicles with night vision assist
Fig. 127 Front of the vehicle: night vision ass ist came ra
The following situations may affect the function
of the night vision assist system:
- Poor visibility such as snow, rain, fog or heavy
spray
- Dirty lens on the night vision assist camera
Make sure the night vision assist camera
c::>fig. 127 is not covered by stickers, deposits or
any other obstructions because that can affect
the camera function . For information on clean­
ing , refer to
c::> page 306 .
The pedestrian and wild anima l recogn it ion de­
pends on the temperature difference between
the person/wild anima l and the background . Peo ­
ple/wild animals may not be detected if the dif­
ference is too small. The pedestrian/wild animal marking and the marking light* deactivate at
Assist
temperatures above approximately 77 °F (25 °C)
and during daylight. If the night vision assist im­
age is selected in the instrument cluster display,
then the
II symbol appears at the top on the
right side.
A WARNING
-Pay attention to traffic and the area around
your vehicle when night vision assist is switch­
ed on. The driver is always responsible for as­
sessing the traffic situation.
- Night vision assist can only warn about peo­
ple and wild animals located within the visu­
al range of the infrared camera. The visual
range corresponds to the image in the in­
strument cluster display.
- Night vision assist may not detect people or
wild animals and mark them if
- they are not in an upright position, for ex­
amp le if they are sitting or lying down
and/or
- the silhouette in the display appears in­
complete or interrupted, for example be­
cause the person is partially covered by a
vehicle or an animal by tall grass. This
could increase the risk of an accident.
- Never try to swerve around animals if doing
so will endanger you or other road users, be­
cause this increases the risk of an accident.
(l'} Tips
- Even though the system evaluates the
shape and heat given off by all detected ob­
jects, there are limits to the system . There
may be false warnings.
- For technical reasons, the image pauses in
split second intervals.
