ESP MERCEDES-BENZ S-Class 2008 W221 Comand Manual

496 Controls in detailDriving systemsSensor monitoring range
Blind Spot Assist is able to monitor a range
up to three meters to the rear and both
sides of the vehicle.
The Blind Spot Assist sensors are built into
t h e f r o n t a n d r e a r b u m p e r s . M a k e s u r e t h a t
the area of the bumpers around the sen-
sors is free of dirt, ice and snow. The radar
sensors must not be obstructed, for exam-
ple, by bicycle carriers or overhanging lug-
gage.
Warning!
G
Blind Spot Assist monitors certain areas in
the immediate vicinity of your vehicle. Vehi-
cles approaching and passing at increased
speeds will not be detected. There will be no
warning display and no audible warning.
When driving in a very wide lane, the sensors
may not be able to cover the entire width of
the neighboring lane. Vehicles driving on the
outside of the neighboring lane may not be
detected.
It is the driver’s responsibility at all times to
be attentive to road, weather and traffic con-
ditions and to provide the steering, braking
and other driving inputs necessary to retain
control of the vehicle. Failure to do so could
result in recognizing dangers too late, possi-
bly resulting in an accident and serious inju-
ry to yourself and others.
When driving in a very narrow lane, the sen-
sors may detect and display vehicles in the
second lane over. This will be the case if
there are vehicles driving on the inside edge
of their lane.!
In the event of a significant impact or dam-
age affecting the bumpers, have the radar sen-
sors checked by a qualified specialist workshop
such as a Mercedes-Benz Center. Failure to do
this can result in Blind Spot Assist not function-
ing correctly.

Indicator and warning lamps
1Yellow indicator lamp/red warning
lamp
Switching on: Make sure that the ra-
dar sensors (
page 307) and Blind
Spot Assist (
page 304) are switched
on.
With the ignition switched on, the warn-
ing lamp1 in the exterior mirror lights
up red.
With the engine running, the indicator
lamp1 in the exterior mirror lights up
yellow up to a speed of 20 mph
(30 km/h).Once a speed above 20 mph (30 km/h)
has been reached and


Blind Spot Assist detects no vehicle in
its range, the indicator lamp1 goes
out


Blind Spot Assist detects another vehi-
cle in its range, the warning lamp1 on
the corresponding side of the vehicle
turns red.Collision warning
If a vehicle is detected in the Blind Spot As-
sist range and you activate the turn signal,
a two-tone warning will sound and the red
warning lamp1 will flash.

Remain on the lane that you are cur-
rently on until traffic conditions permit
to change.
If the turn signal remains on, the red warn-
ing lamp1 will flash to indicate that vehi-
cles have been detected. No further
audible warnings will sound.
Warning!
G
Blind Spot Assist is not active at speeds be-
low approximately 20 mph (30 km/h). You
will not be alerted to the presence of vehi-
cles in the monitored area at these speeds.
It is the driver’s responsibility at all times to
be attentive to road, weather and traffic con-
ditions and to provide the steering, braking
and other driving inputs necessary to retain
control of the vehicle. Failure to do so could
result in recognizing dangers too late, possi-
bly resulting in an accident and serious inju-
ry to yourself and others.
Warning!
G
Do not change lanes or make turns, while
the red warning lamp
1
is flashing. Doing
so could result in an accident and seroius in-
jury to yourself and others.

Maximum cooling MAXCOOL (USA only)
If U is selected on both the left and
right side and there is a high demand for
cooling, the display “MAXCOOL” appears
in the COMAND display.
This provides the fastest possible cooling
of the vehicle interior (when windows and
tilt/sliding sunroof or tilt/sliding panel*
are closed).
Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside (e.g. before driving in a
tunnel). This setting cuts off the intake of
outside air and recirculates the air in the
passenger compartment.
!
The rear window defroster uses a large
amount of power. To keep battery drain to a min-
imum, switch off the defroster as soon as the
rear window is clear.
i
The defroster is automatically deactivated
after some time of operation depending on the
outside temperature.
Warning!
G
Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.i
If the rear window defroster switches off too
soon and the indicator lamp goes out, this indi-
cates that too many electrical consumers are op-
erating simultaneously and the load on the
battery is reducing available voltage. The system
responds automatically by deactivating the rear
window defroster.
i
Maximum cooling MAXCOOL is only avail-
able when the engine is running.Warning!
G
Fogged windows impair visibility, endanger-
ing you and others. If the windows begin to
fog on the inside, switching off the air
recirculation mode immediately should clear
interior window fogging. If interior window
fogging persists, make sure the air
conditioning (
page 276) is activated, or
press button;.

Observe manufacturer’s instructions
for installation.
Loading instructions
The total load weight including vehicle oc-
cupants and luggage/cargo should not
exceed the load limit as indicated on the
corresponding placard located on the driv-
er’s door B-pillar (
page 585).
Warning!
G
Only use roof racks approved by
Mercedes-Benz for your vehicle model to
avoid damage to the vehicle.
Follow the manufacturer’s installation
instructions. Otherwise, an improperly
attached roof rack system or its load could
become detached from the vehicle.
Do not exceed the maximum roof load of
220 lb (100 kg).
Take into consideration that when the roof
rack is loaded, the handling characteristics
are different from those when operating the
vehicles without the roof rack loaded.
!
Load the roof rack in such a way that the ve-
hicle cannot be damaged while driving.
Make sure


you can fully raise tilt/sliding sunroof or the
panorama roof with tilt/sliding panel*


you can fully open the trunk
Warning!
G
Always fasten items being carried as secure-
ly as possible using cargo tie-down hooks
and fastening materials appropriate for the
weight and size of the load.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle and can cause in-
jury to vehicle occupants unless the items
are securely fastened in the vehicle.

Warning!
G
Do not place objects with a combined
weight of more than 4.4 lbs (2 kg) into the
ruffled storage pocket. Otherwise, the Occu-
pant Classification System OCS (
page 47)
may not be able to properly approximate the
occupant weight category.
The ruffled storage pocket is intended for
storing light-weight items only.
Heavy objects, objects with sharp edges or
fragile objects may not be transported in the
ruffled storage pocket. In an accident, dur-
ing hard braking, or sudden maneuvers, they
could be thrown around inside the vehicle
and cause injury to vehicle occupants.
The ruffled storage pocket cannot protect
transported goods in the event of an acci-
dent.
Warning!
G
In order to help prevent spilling liquids on
vehicle occupants and/or vehicle equip-
ment, only use containers that fit into the
cupholder. Use lids on open containers and
do not fill containers to a height where the
contents, especially hot liquids, could spill
during braking, vehicle maneuvers, or in an
accident. Liquids spilled on vehicle occu-
pants may cause serious personal injury.
Liquids spilled on vehicle equipment may
cause damage not covered by the
Mercedes-Benz Limited Warranty.
When not in use, keep the cupholders
closed. An open cupholder may cause injury
to you or others when contacted during
braking, vehicle maneuvers, or in an acci-
dent.
