Active Blind Spot Assist monitors the area up to
3.0 m behi nd your vehicle and directly next to
your vehicle, as shown in the diagram.
In particular, the detection of obstacles can be
impaired in the following situations:
R dirt on the sensors or obscured sensors
R poor visibility, e.g. due to rain, snow or spray
Vehicles in the monitoring range are then not
reliably indicated.
Active Blind Spot Assist may not detect narrow
vehicles, such as motorcycles or bicycles, or
may only detect them too late.
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 driv-
ing in the middle of their lane. This may be the
case if there are vehicles at the edge of their
lane.
On very wide lanes, vehicles in the lane next to
your vehicle may not be displayed if the vehicles
are too far away.
The nature of the system may result in the fol-
lowing:
R Warnings may be issued in error when you are
driving close to crash barriers or similar solid boundaries
R Warnings may be interrupted when you are
driving alongside particularly long vehicles,
for example lorries, for a prolonged time Indicator and warning display
:
Yellow indicator lamp/red warning lamp
Active Blind Spot Assist is not operational at
speeds of below approximately 30 km/h. Vehi-
cles in the monitoring range are then not indi-
cated.
If Active Blind Spot Assist is switched on, indi-
cator lamp :in the exterior mirrors lights up
yellow up to a speed of 30 km/h. At speeds
above 30 km/h, the indicator lamp goes out and Active Blind Spot Assist is operational.
If a vehicle is detected within the monitoring
range at speeds above 30 km/h, warning
lamp :on the corresponding side lights up red.
This warning lamp always lights up when a vehi- cle enters the blind spot monitoring range from
behind or from the side. When you overtake a
vehicle with a difference in speed of less than
12 km/h, a delayed warning occurs.
The yellow indicator lamp goes out if reverse
gear is engaged. Active Blind Spot Assist is not
operational.
The brightness of the indicator/warning lamps
is adjusted automatically according to the
brightness of the surroundings.
Visual and acoustic collision warning If you switch on the turn signals to change lanes
and a vehicle is detected in the side monitoring range, you receive a visual and acoustic collision
warning. You then hear a double warning tone
and red warning lamp :flashes. If the turn sig-
nal remains on, detected vehicles are indicated
by the flashing of red warning lamp :. No fur-
ther warning tones are issued.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of a side impact in the monitoring range, a course-cor-
recting brake application is carried out. This is
designed to help you avoid a collision. Driving systems
223Driving and parking Z
G
WARNING
A course-correcting brake application cannot always prevent a collision. There is a risk of an
accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake appli-
cation. Always maintain a safe distance at the sides.
If a course-correcting brake application occurs, red warning lamp :flashes in the exterior mir-
ror and a dual warning tone sounds. In addition, display underlining the danger of a side collision
appears in the multifunction display.
In very rare cases, the system may make an
inappropriate brake application. A course-cor-
recting brake application may be interrupted at any time if you steer slightly in the opposite
direction or accelerate.
The course-correcting brake application is avail-
able in the speed range between 30 km/h and
200 km/h.
Either a course-correcting brake application
appropriate to the driving situation, or none at
all, may occur in the following situations:
R there are vehicles or obstacles, e.g. crash
barriers, close to both sides of your vehicle
R a vehicle approaches too closely on the side
R you have adopted a sporty driving style with
high cornering speeds
R you brake or accelerate significantly
R a driving safety system engages, such as
ESP ®
or PRE-SAFE ®
Brake
R ESP ®
is deactivated
R the Offroad program is activated (vehicles
without the Off-Road Engineering package)
R the Offroad or Offroad Plus drive program is
activated (vehicles with the Off-Road Engi-
neering package)
R the LOW RANGE off-road gear is activated
(vehicles with the Off-Road Engineering pack-
age)
R a loss of tyre pressure or a defective tyre is
detected Activating Active Blind Spot Assist

Active Lane Keeping Assist General notes
Active Lane Keeping Assist monitors the area in
front of your vehicle by means of multifunction
camera :at the top of the windscreen. Various
different areas to the front, rear and side of your vehicle are also monitored with the aid of the
radar sensor system. Active Lane Keeping
Assist detects lane markings on the road and
can warn you before you leave your lane unin-
tentionally. If you do not react to the warning, a
lane-correcting application of the brakes can
bring the vehicle back into the original lane.
This function is available within a speed range
between 60 km/h and 200 km/h.
For Active Lane Keeping Assist to assist you
when driving, the radar sensor system must be
operational. 224
Driving systemsDriving and parking
If you leave your lane under certain circumstan-
ces, the vehicle will brake briefly on one side.
This is intended to help you return the vehicle to
the original lane.
If a lane-correcting brake application occurs,
display :appears in the multifunction display.
A lane-correcting brake application can be made
after driving over a lane marking recognised as
being solid or broken. Before this, a warning
must have been issued by means of intermittent
vibration through the steering wheel. In addi-
tion, a lane with lane markings on both sides
must be detected.
In the case of a broken lane marking being
detected, a lane-correcting brake application
can only be made if a vehicle has been detected
in the adjacent lane. The following vehicles can have an influence on brake application: oncom- ing traffic, vehicles that are overtaking and vehi-
cles that are driving parallel to your vehicle.
i A further lane-correcting brake application
can only occur after your vehicle has returned
to the original lane.
No lane-correcting brake application occurs if: R you clearly and actively steer, brake or accel-
erate
R you cut the corner on a sharp bend
R you have switched on the turn signal
R a driving safety system intervenes, such as
ESP ®
, PRE-SAFE ®
Brake or Active Blind Spot
Assist
R you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
R ESP ®
is deactivated
R the transmission is not in position D
R on vehicles with a trailer tow hitch, the elec-
trical connection to the trailer has been cor-
rectly established R

(vehicles with the Off-Road Engineering pack-
age)
R an obstacle has been detected in the lane in
which you are driving
R a loss of tyre pressure or a defective tyre has
been detected and displayed
There is a possibility that the Active Lane Keep-
ing Assist could misjudge the given traffic sit-
uation. An inappropriate brake application may
be interrupted at any time if:
R you steer slightly in the opposite direction
R you switch on the turn signal
R you clearly brake or accelerate
A lane-correcting brake application is interrup-
ted automatically if:
R a driving safety system intervenes, such as

LOW RANGE offroad gear (vehicles with
the Off-Road Engineering package) Important safety notes
G
WARNING
If you select the LOW RANGE off-road gear on a slippery road surface, the wheels could lose traction:
R if you release the accelerator pedal when
the vehicle is in motion
R if Off-road ABS intervenes when braking
If the wheels lose traction, it will no longer be
possible to steer the vehicle. This increases
the risk of skidding and having an accident.
Never select the LOW RANGE off-road gear
when driving on slippery road surfaces. G
WARNING
If you do not wait for the transfer case gear
change process to complete, the transfer
case could remain in the neutral position. The power transmission to the driven wheels is
then interrupted. There is a danger of the
vehicle rolling away unintentionally. There is a
risk of an accident.
Wait until the transfer case shift process is
completed.
Do not turn off the engine while changing gear
and do not shift the automatic transmission to
another position. 230
