The 00CE indicator lamp in the instrument
cluster goes out. Adaptive Highbeam Assist PLUS
General notes With Adaptive Highbeam Assist Plus, you can
automatically switch between low-beam,
partial high-beam and high-beam headlamps.
Partial high-beam is a form of illumination
whereby the high-beam is directed past other
road users. Other road users are kept out of
the high-beam. This prevents glare. When
there is a vehicle in front, for example, the
high-beam headlamps illuminate the areas to
its right and left, and the vehicle in front is
illuminated by the low-beam headlamps.
The system automatically adapts the low-
beam headlamp range depending on the
distance to the other vehicle. Once the
system no longer detects any other vehicles,
it reactivates the high-beam headlamps.
If the high-beam or partial high-beam are
causing too much reflection from traffic signs, the lights are automatically dimmed
and glare for the driver caused by the
reflections is thus avoided.
The system's optical sensor is located behind
the windshield near the overhead control
panel.
Important safety notes
G
WARNING
Adaptive Highbeam Assist Plus does not
recognize road users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
In very rare cases, Adaptive Highbeam Assist
Plus may not recognize road users who do
have lights, or may recognize them too late.
In this or similar situations, the automatic
high-beam headlamps will not be deactivated
or will be activated regardless. There is a risk
of an accident.
Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time.
Adaptive Highbeam Assist Plus cannot take
into account road, weather or traffic
conditions. Adaptive Highbeam Assist Plus is
only an aid. You are responsible for adjusting
the vehicle's lighting to the prevailing light,
visibility and traffic conditions.
In particular, the detection of obstacles can
be restricted if there is:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or the sensors are
obscured Exterior lighting

Replacing the wiper blades
Important safety notes G
WARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could
be trapped by the wiper arm. There is a risk
of injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
! To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper.
! Never open the hood if a windshield wiper
arm has been folded away from the
windshield.
Never fold a windshield wiper arm without
a wiper blade back onto the windshield.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield, the
windshield may be damaged by the force of
the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified
specialist workshop.

Problems with the engine
Problem Possible causes/consequences and
0050
0050Solutions The engine does not
start. The starter motor
can be heard. R
There is a malfunction in the engine electronics.
R There is a malfunction in the fuel supply.
X Before attempting to start the engine again, turn the SmartKey
in the ignition back to position 0or press the Start/Stop button
repeatedly until all indicator lamps in the instrument cluster go
out.
X Try to start the engine again (Y page 173). Avoid excessively
long and frequent attempts to start the engine as these will drain
the battery.
If the engine does not start after several attempts:
X Consult a qualified specialist workshop. The engine does not
start. You cannot hear
the starter motor. The on-board voltage is too low because the battery is too weak
or discharged.
X
Jump-start the vehicle (Y page 373).
If the engine does not start despite attempts to jump-start it:
X Consult a qualified specialist workshop. The starter motor was exposed to a thermal load that was too high.
X
Try to start the engine again.
If the engine still does not start:
X Consult a qualified specialist workshop. The engine is not
running smoothly and
is misfiring. There is a malfunction in the engine electronics or in a mechanical
component of the engine management system.
X
Only depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic
converter and damage it.
X Have the cause rectified immediately at a qualified specialist
workshop. The coolant
temperature gauge
shows a value above
248 ‡ (120 †). The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant
to cool down.
X Check the coolant level (Y page 351). Observe the warning
notes as you do so and add coolant if necessary. 178

level ground and secure it to prevent it
rolling away.
X Shift the automatic transmission to
position P.
It may not be possible to release an applied
parking brake, if the on-board voltage is low
or there is a malfunction in the system.
Contact a qualified specialist workshop.
