warning MERCEDES-BENZ GL 2014 Owners Manual

Active Parking Assist may possibly indicate
parking spaces which are not suitable for
parking, for example:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces
Parking tips:
ROn narrow roads, drive as close to the
parking space as possible.
RParking spaces that are littered or
overgrown might be identified or measured
incorrectly.
RParking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly.
RSnowfall or heavy rain may lead to a parking
space being measured inaccurately.
RPay attention to the PARKTRONIC
(Ypage 224) warning messages during the
parking procedure.
RAt any time, you can intervene in the
steering procedure to correct it. Active
Parking Assist will then be canceled.
RWhen transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
RNever use Active Parking Assist when snow
chains are installed.
RMake sure that the tire pressures are
always correct. This has a direct influence
on the parking characteristics of the
vehicle.
Use Active Parking Assist for parking spaces:
Rthat are parallel to the direction of travel
Rthat are on straight roads, not bends
Rthat are on the same level as the road, e.g.
not on the pavement
Detecting parking spaces
Objects located above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking
procedure is calculated, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles.
GWARNING
If there are objects above the detection range,
Active Parking Assist may turn prematurely.
You may cause a collision as a result. There is
a risk of an accident.
If there are objects above the detection range,
stop and deactivate Active Parking Assist.
For further information on the detection
range (Ypage 223).
Active Parking Assist does not support you
with parking spaces parallel to the direction
of travel if:
Rthe parking space is on a curb
Rthe system reads the parking space as
being blocked, for example by foliage or
grass paving blocks
Rthe area is too small for the vehicle to
maneuver into
Rthe parking space is bordered by an
obstacle, e.g. a tree, a post or a trailer
CDetected parking space on the left
DParking symbol

Active Parking Assist will only detect parking
spaces:
Rthat are parallel to the direction of travel
Rthat are at least 59 in (1.5 m) wide
Rthat are at least 51 in (1.3 m) longer than
your vehicle
When driving at speeds below 19 mph
(30 km/h), you will see parking symbol as a
status indicator in the instrument cluster.
When a parking space has been detected, an
arrow towards the right or the left also
appears. By default, Active Parking Assist
only displays parking spaces on the front-
passenger side. Parking spaces on the
driver's side are displayed as soon as the turn
signal on the driver's side is activated. When
parking on the driver's side, this must remain
switched on until you acknowledge the use of
Active Parking Assist by pressing thev
button on the multifunction steering wheel.
A parking space is displayed while you are
driving past it, and until you are
approximately 50 ft (15 m) away from it.

Parking tips:
RThe way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the
position and shape of the vehicles parked
in front and behind it and the conditions of
the location. It may be the case that Active
Parking Assist guides you too far into a
parking space, or not far enough into it. In
some cases, it may also lead you across or
onto the curb. If necessary, you should
cancel the parking procedure with Active
Parking Assist.
RYou can also select preselect transmission
positionD. The vehicle redirects and does
not drive as far into the parking space.
Should the gear change occur too soon to
achieve a sensible parking position, the
parking procedure will be aborted.
Exiting a parking space
In order that Active Parking Assist can
support you when you exit the parking space:
Ryou need to have parked using Active
Parking Assist.
Rthe border of the parking space must be
high enough at the front and the rear. A
curb stone is too small, for example.
Rthe border of the parking space must not
be too wide, as the position of the vehicle
must not exceed an angle of 45° to the
starting position as it is maneuvered into
the parking space.
Ra maneuvering distance of at least 3.3 ft
(1.0 m) must be available.

Night View Assist Plus
General notes
In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminate the road.
Night View Assist Plus cameraCpicks up
the infrared light and displays a monochrome
image in COMAND. The image displayed in
COMAND corresponds to a road lit up by high-
beam headlamps. This enables you to see the
road's course and any obstacles in good time.
If pedestrian recognition is activated,
pedestrians recognized by the system are
highlighted in the Night View Assist Plus
display.
Light from the headlamps of oncoming
vehicles does not affect the Night View Assist
Plus display in the multifunction display. This
is also the case if you cannot switch on the
high-beam headlamps due to oncoming
traffic.
iInfrared light is not visible to the human
eye and therefore does not glare. Night
View Assist Plus can therefore remain
switched on even if there is oncoming
traffic.
Important safety notes
Night View Assist Plus is only an aid and is not
a substitute for attentive driving. Do not rely
on the Night View Assist Plus display. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time. Drive carefully and always adapt
your driving style to suit the prevailing road
and traffic conditions.
The system may be impaired or may not
function if:
Rthere is poor visibility, e.g. due to snow,
rain, fog or spray
Rthe windshield is dirty, fogged up or
covered, for instance by a sticker, in the
vicinity of the camera

Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist (Ypage 243) and Lane Keeping
Assist (Ypage 245).
Blind Spot Assist
General notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from a speed of
approximately 20 mph(30 km/h). A warning
display in the exterior mirrors draws your
attention to vehicles detected in the
monitored area. If you then switch on the
corresponding turn signal to change lanes,
you will also receive a visual and audible
collision warning. Blind Spot Assist uses
sensors in the rear bumper for monitoring
purposes.
Important safety notes
GWARNING
Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions
carefully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving.
iUSA only:
This device has been approved by the FCC
as a "Vehicular Radar System". The radar
sensor is intended for use in an automotive

FCC. Do not tamper with, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
Monitoring range of the sensors
In particular, the detection of obstacles can
be impaired if:
Rdirt on the sensors or anything else
covering the sensors
Rpoor visibility, e.g. due to fog, heavy rain,
snow or spray
Rnarrow vehicles, e.g. motorcycles or
bicycles
Rthe road has very wide lanes
Rthe road has narrow lanes
Ryou are not driving in the middle of the lane
Rthere are barriers or similar lane borders
Vehicles in the monitoring range are then not
indicated.
Blind Spot Assist monitors the area up to
10 ft (3 m) behind your vehicle and directly
next to your vehicle, as shown in the diagram.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may
be indicated, especially if the vehicles are not
driving in the middle of their lane. This may
be the case if there are vehicles driving at the
inner edge of their lanes.
Due to the nature of the system:
Rwarnings may be issued in error when
driving close to crash barriers or similar
solid lane borders.
Rthe warning is canceled when driving for an
extended period next to long vehicles, such
as trucks.
The two radar sensors for Blind Spot Assist
are integrated into the sides of the rear
bumper. Make sure that the bumper is free of
dirt, ice or slush in the vicinity of the sensors.
The sensors must not be covered, for
example by cycle racks or overhanging loads.
Following a severe impact or in the event of
damage to the bumpers, have the condition
of the radar sensors checked at a qualified
specialist workshop. Blind Spot Assist may
otherwise not work properly.
Indicator and warning display
Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated.
CYellow indicator lamp/red warning lamp
When Blind Spot Assist is activated, indicator
lampCin the exterior mirrors lights up
yellow at speeds of up to 20 mph(30 km/h).

In this case, Lane Keeping Assist may:
Rgive an unnecessary warning
Rnot give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist.
GWARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There
is a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane
Keeping Assist.
If you fail to adapt your driving style, Lane
Keeping Assist can neither reduce the risk of
an accident nor override the laws of physics.
Lane Keeping Assist cannot take into account
the road, traffic and weather conditions. Lane
Keeping Assist is merely an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
The Lane Keeping Assist does not keep the
vehicle in the lane.
The system may be impaired or may not
function if:
Rthere is poor visibility, e.g. due to
insufficient illumination of the road, or due
to snow, rain, fog or spray
Rthere is glare, e.g. from oncoming traffic,
the sun or reflections (e.g. when the road
surface is wet)
Rthe windshield is dirty, fogged up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
Rthere are no, several or unclear lane
markings for a lane, e.g. in areas with road
construction work
Rthe lane markings are worn away, dark or

The Active Driving Assistance package
consists of DISTRONIC PLUS (Ypage 203),
Active Blind Spot Assist (Ypage 247) and
Active Lane Keeping Assist (Ypage 251).
Active Blind Spot Assist
General notes
Active Blind Spot Assist uses a radar sensor
system to monitor the side areas of your
vehicle which are behind the driver. A warning
display in the exterior mirrors draws your
attention to vehicles detected in the
monitored area. If you then switch on the
corresponding turn signal to change lane, you
will also receive an optical and audible
warning. If a risk of lateral collision is
detected, corrective braking may help you
avoid a collision. Active Blind Spot Assist
evaluates the free space in the direction of
travel and to the side before making a course-
correcting brake application. For this, Active
Blind Spot Assist uses radar sensors which
are pointed in the direction of travel.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
Important safety notes
Active Blind Spot Assist is only an aid. It may
fail to detect some vehicles and is no
substitute for attentive driving.
GWARNING
Active Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
As a result, Active Blind Spot Assist may
neither give warnings nor intervene in such
situations. There is a risk of an accident.
Always observe the traffic conditions
carefully, and maintain a safe lateral distance.
