General information WARNING
With the engine hot and the cooling sys‐
tem open, coolant can escape and lead to
burns. There is risk of injuries. Only open the
cooling system with the engine cooled down. ◀
WARNING
Additives are harmful and incorrect addi‐
tives can damage the engine. There is risk of in‐
juries and risk of property damage. Avoid the
contact of articles of clothing, skin or eyes with
additives. Do not swallow any additives. Use
suitable additives only. ◀
Coolant consists of water and additives. Not all commercially available additives are
suitable for the vehicle. Information regarding
suitable additives is available from a dealer’s
service center or another qualified service cen‐
ter or repair shop.Coolant temperature
If the coolant and therefore the engine over‐
heat, a warning lamp lights up, refer to
page 194.
Coolant level Checking1.Do not open the hood until the engine has
cooled down.2.Turn the expansion tank cap counterclock‐
wise slightly to allow any accumulated
pressure to escape; then continue turning
to open.3.The coolant level is correct if it is between
the markings. The markings are located on
the side of the coolant reservoir.
Refilling
1.Do not open the hood until the engine has
cooled down.2.Turn the expansion tank cap counterclock‐
wise slightly to allow any accumulated
pressure to escape, then continue turning
to open.3.If the coolant level is low, slowly add cool‐
ant up to the specified level; do not overfill.Seite 170MOBILITYCoolant170

The manufacturer of your vehicle recommends
that maintenance and repair be performed by a
dealer’s service center or another qualified
service center or repair shop. Records of regu‐
lar maintenance and repair work should be re‐
tained.
Socket for OBD Onboard
Diagnosis
CAUTION
The socket for Onboard Diagnosis is an
intricate component intended to be used in
conjunction with specialized equipment to
check the vehicle’s primary emissions system.
Improper use of the socket for Onboard Diag‐
nosis, or contact with the socket for Onboard
Diagnosis for other than its intended purpose,
can cause vehicle malfunctions and creates
risks of personal and property damage. Given
the foregoing, the manufacture of your vehicle
strongly recommends that access to the socket
for Onboard Diagnosis be limited to a dealer's
service center or another qualified service cen‐
ter or repair shop or other persons that have
the specialized training and equipment for pur‐
poses of properly utilizing the socket for On‐
board Diagnosis. ◀
Primary components in the vehicle emissions
can be checked via the OBD socket using a de‐
vice.
Emissions
The warning lamps light up. The vehicle
is producing higher emissions. Further
driving at a moderate pace is possible.
Have the vehicle checked as soon as possible.
Under certain circumstances, one of the lamps
flashes or lights up continuously. This indicates
that there is excessive misfiring or a malfunc‐
tion in the engine. In this situation, decrease
the vehicle speed and immediately drive to a
dealer’s service center or another qualified
service center or repair shop. Serious engine
misfiring within a brief period can seriously
damage emission control components, in par‐
ticular the catalytic converter. In addition, the
mechanical engine components may become
damaged.
If the fuel filler cap is not properly tight‐
ened, the OBD system may conclude
that fuel vapor is escaping; this will
cause a display to light up. If the filler cap is
then tightened, the display should go out in a
few days.Seite 173MaintenanceMOBILITY173

Information
Lamps and bulbs Lamps and bulbs make an essential contribu‐
tion to vehicle safety. Therefore, exercise cau‐
tion when handling lights and bulbs.
The vehicle manufacturer recommends that
you have the necessary work performed by a
dealer’s service center or another qualified
service center or repair shop if you are unfami‐
liar with it or it is not described here.
A spare lamp box is available from a dealer’s
service center or another qualified service cen‐
ter or repair shop.
WARNING
Bulbs can get hot during operation. Con‐
tact with the bulbs can cause burns. There is
risk of injuries. Only change bulbs after they
have cooled off. ◀
WARNING
Work on switched-on lighting systems
can cause short circuits. There is risk of injuries
or risk of property damage. When working on
the lighting system, switch off the lamps in
question. If necessary, heed the bulb manufac‐
turer's instructions. ◀
CAUTION
Contaminated bulbs reduce their service
life. There is risk of property damage. Do not
hold new bulbs with your bare hands. Use a
clean cloth or something similar, or hold the
bulb by its base. ◀
Caring for the headlights, refer to page 191.
For bulb replacement procedures that are not
described here, contact a dealer’s service cen‐
ter or another qualified service center or repair
shop.
For checking and adjusting headlamp aim, con‐
tact a dealer’s service center or another quali‐
fied service center or repair shop.
Light-emitting diodes LEDs In some equipment, the light source is provided
by light-emitting diodes behind a cover.
These light-emitting diodes, which operate us‐
ing a concept similar to that applied in conven‐
tional lasers, are designated as Class 1 light-
emitting diodes.
WARNING
Too intensive brightness can irritate or
damage the retina of the eye. There is risk of
injuries. Do not look directly into the headlights
or other light sources for an extended period of
time. Do not remove the LED covers. ◀
Headlight glass
Condensation can form on the inside of the ex‐
ternal lights in cool or humid weather. When
you drive with the lights switched on, the con‐
densation evaporates after a short time. The
headlight glass does not need to be changed.
If despite driving with the lights switched on,
increasing humidity forms, e. g. water droplets
in the lamp, the manufacturer of your vehicle
recommends having it checked by a dealer’s
service center or another qualified service cen‐
ter or repair shop.
Bi-xenon headlights
These bulbs have a very long life and the likeli‐
hood of failure is very low, provided that they
are not switched on and off excessively. If a
bulb should nevertheless fail, you can continueSeite 175Replacing componentsMOBILITY175

driving cautiously with the front fog lights, pro‐
vided this is permitted by local laws.
DANGER
There can be high voltage in the lighting
system. There is danger to life. The manufac‐
turer of your vehicle recommends that the
work on the lighting system including bulb re‐
placement be performed by a dealer’s service
center or another qualified service center or re‐
pair shop. ◀
