2009 MERCEDES-BENZ E-CLASS SALOON lock

Information and warning display
:
Yellow indicator lamp/red warning lamp
When you turn the key to position 2in the
ignition lock, warning lamps :in the exterior
mirrors light up red.
If Blind Spot Assist is switched on and the
engine is running, indicator lamps :in the
exterior mirrors light up yellow up to a speed
of 30 km/h. At speeds above 30 km/h, the
indicator lamp goes out and Blind Spot Assist
is operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp :on the corre-
sponding side lights up red. This warning is
always issued when a vehicle enters the blind
spot monitoring range from behind or from
the side. When you overtake a vehicle, the
warning only occurs if the difference in speed
is less than 12 km/h.
The yellow indicator lamp goes out after
reverse gear is engaged. In this event, Blind
Spot Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light. G
Risk of accident
Blind Spot Assist is not active at speeds below
30 km/h, and the indicator lamps in the exte-
rior mirrors are yellow. Vehicles in the moni-
toring range are then not indicated.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to recognise dangers in time, cause an accident
and injure yourself and others.
Collision warning
If a vehicle is detected in the monitoring range
of Blind Spot Assist and you switch on the turn
signal, a double warning tone sounds. Red
warning lamp :flashes. If the turn signal
remains on, detected vehicles are indicated
by the flashing of red warning lamp :. There
are no further warning tones.
Switching on Blind Spot Assist
X Make sure that the radar sensor system
(Y page 134) and Blind Spot Assist
(Y page 130) are activated in the on-board
computer.
X Turn the key to position 2in the ignition
lock.
Red warning lamps :in the exterior mir-
rors are lit.
X Start the engine.
Warning lamps :in the exterior mirrors

Trailer towing*
Blind Spot Assist is deactivated when you
connect the trailer to your vehicle electrically.
The Blind Spot Assist currently
unavailable See Owner's Manual mes-
sage appears in the multi-function display.
Lane Keeping Assist If you select
kmon the on-board computer in
the Speed-/odometer: function
(Y page 131), Lane Keeping Assist is activa-
ted starting at a speed of 60 km/h. If the
miles display unit is selected, the assistance
range begins at between 35 and 40 mph.
Lane Keeping Assist is designed to detect
lane markings on the road and warn you
before you leave your lane unintentionally.
Usually the warning is given when a front
wheel passes over a lane marking. It will warn
you by means of intermittent vibration in the
steering wheel for up to 1.5 seconds. Driving systems

Lane Keeping Assist monitors the area in
front of your vehicle by means of a camera at
the top of the windscreen. :
Lane Keeping Assist camera
In order that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system recognises certain con-
ditions and warns you accordingly.
The warning occurs earlier if:
R you cut a corner on the outside.
R the road has very wide lanes, e.g. a motor-
way.
R the system recognises solid lane markings,
as crossing these often results in a critical
situation, e.g. in the case of hard shoulders
or crash barriers.
The warning occurs later if:
R the road has narrow lanes.
R you cut a corner on the inside.
No warning occurs if:
R you actively steer, brake or depress the
accelerator pedal, e.g. when changing lane,
overtaking, accelerating or leaving the
motorway.
R you cut the corner on a sharp bend.
R you drive around a very sharp bend.
R you switch on the turn signals. In this event
the warnings are suppressed for a certain
period of time.
R a driving safety system intervenes, such as
ABS, BAS or ESP ®
. G
Risk of accident
Lane Keeping Assist does not keep your vehi-
cle in its lane. It is only an aid and may detect
the lane markings on the road incorrectly or
not at all.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to snow,
rain, fog or spray.
R there is glare, e.g. from the sun or from
oncoming traffic.
R the windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity
of the camera.
R there are no lane markings.
R the lane markings are worn away, dark or
covered up, e.g. by dirt or snow.
R the distance to the vehicle in front is too
short.
R there are ambiguous lane markings on the
road, e.g. near roadworks.
R there are short-term changes to the mark-
ings, e.g. filter lanes or motorway exits.
R the road is narrow and winding.
Lane Keeping Assist cannot detect road and
traffic conditions. It is not a substitute for
attentive driving.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others.

tion system with a cooling system. You can
control the temperature separately for the

windows and sliding/tilting sunroof*/pano-
rama sliding sunroof* closed.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 102).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filters out
pollen. A clogged filter reduces the amount of air supplied to the vehicle interior. For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Service Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet. G
Risk of accident
Observe the recommended settings on the
following pages. Otherwise, the windows
could mist up. This may prevent you from
observing the traffic conditions, thereby caus-
ing an accident. Overview of air-conditioning system functions

flow and air distribution of the automatic
air conditioning to one of three levels
(FOCUS/MEDIUM/DIFFUSE). You can
set the desired level using button G. The
MEDIUM level is recommended.

Risk of accident
If you switch off the "Cooling with air dehu-
midification" function, the air inside the vehi-
cle will not be cooled (in warm weather) or
dehumidified. The windows could mist up
more quickly. This may prevent you from
observing the traffic conditions and thereby
cause an accident.
Condensation may drip from the underside of
the vehicle when Thermatic is in cooling
mode.

matically
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic air conditioning will achieve
optimal operation if "cooling with air dehu-
midification" is also activated. If necessary,
cooling with air dehumidification can be deac-
tivated.

Risk of injury
Very hot or very cold air can flow from the air
vents. This could cause burns or frostbite to
bare skin in the immediate vicinity of the air
vents. Keep bare skin away from these air
vents. If necessary, direct the airflow to a dif-
ferent area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet between the windscreen
and the bonnet free of blockages, such as
ice, snow or leaves.
R never cover the vents or air inlet and outlet
grilles in the vehicle interior.
i For virtually draught-free ventilation,
adjust the sliders of the air vents to the
centre position.
