On-Board Diagnostics
F ig. 6 Location of Data Link Connecto r (DLC)
On-Board Diagnostics monitors the components
of yo ur emission control system. Each monitored
component in your eng ine system has been as­
signed a code. In case of a ma lfunction, the com­
ponent wi ll be identified and the fault stored as a
code in the control module memory.
The MIL light may also ill uminate if there is a
leak in the on -board fuel vapor recovery system.
If the light illuminates after a refuelling, stop
the vehicle and make sure the fuel filler cap is
properly closed¢
page 186.
In order to make an accurate diagnosis, the stor­
ed data can on ly be displayed using specia l diag­

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.

cluster if there is a malfunction in the light

(D Note
- Applies to vehicles with power fo lding out­

moved by outside forces (such as an impact
when maneuvering), you must use the pow­
er foldi ng function to fold the mirror all the
way out. You will hear a loud noise when the
mirrors are latched back in place. The mirror

Lights and Vision
-Applies to vehicles without power folding
outside mirrors: if the mirror housing was
moved by outside forces (such as an impact
when maneuvering), you must move it back
in place by hand.
-If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in to reduce the risk of damage to the mirrors.
Never fold power folding exterior m irrors*

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 .
(D Tips
- If the light reaching the rearview mirror is
obstructed, the automatic dimm ing mirror
will not function correctly,
- The automatic dimming m irrors do not dim
when the interior lighting is turned on or
the reverse gear is selected .
