Warning lamp
Blind Spot Assist is not active at speeds below
approximately 30 km/h. Vehicles in the moni-
toring range are then not indicated.
If a vehicle is detected within the blind spot
monitoring range at speeds above approx-
imately 30 km/h, warning lamp :on the cor-
responding side lights up red. This warning lamp always lights up when a vehicle enters the blindspot monitoring range from behind or from the
side. When you overtake a vehicle, the warning
occurs only if the difference in speed is less than
12 km/h.
If you select reverse gear, Blind Spot Assist is
not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings.
Collision warning
If a vehicle is detected in the blind spot moni-
toring range and you switch on the correspond-
ing turn signal, a double warning tone sounds.
The red warning lamp flashes on the relevant
exterior mirror. If the turn signal remains on,
detected vehicles are indicated by the flashing
of the red warning lamp on the exterior mirror.
There are no further warning tones.
Activating Blind Spot Assist

Lane Keeping Assist General notes
Lane Keeping Assist monitors the area in front of
your vehicle by means of multifunction cam-
era :attached at the top of the windscreen.
Lane Keeping Assist detects lane markings on
the road and can warn you before you leave your lane unintentionally. Driving systems
211Driving and parking Z

This function is available in a speed range
between 60 km/h and 200 km/h.
A warning may be given if a front wheel passes
over a lane marking. It will warn you by means of intermittent vibration through the steering
wheel for up to 1.5 seconds.
Important safety notes G
WARNING
Lane Keeping Assist cannot always clearly
identify lane markings.
In these cases, Lane Keeping Assist may:
R give an unnecessary warning
R not give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep in lane, especially if Lane
Keeping Assist alerts you. G
WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is a risk of an accident.
Always steer, apply the brakes or accelerate
the vehicle yourself, especially if Lane Keep-
ing Assist alerts you.
Lane Keeping Assist can neither reduce the risk
of an accident if you fail to adapt your driving
style nor override the laws of physics. Lane
Keeping Assist cannot take into account road,
weather or traffic conditions. Lane Keeping
Assist is only 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
lane.
Lane Keeping Assist does not keep your vehicle in its lane.
The system may be impaired or may not function
in the following situations:
R poor visibility, e.g. due to insufficient illumi-
nation of the road, or due to snow, rain, fog or
spray
R glare, e.g. from oncoming traffic, the sun or
reflection from other vehicles (e.g. if the road
surface is wet)
R the windscreen is dirty, misted up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera R
no or several, unclear lane markings are pres-
ent for one lane, e.g. in a construction area
R the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
R the distance to the vehicle in front is so small
that the lane markings cannot be detected
R the lane markings change quickly, e.g. lanes
branch off, cross one another or merge
R the road is very narrow and winding
R there are highly variable shade conditions on
the road surface

Visual and audible 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 audible collision warning. You will then hear a double warning
tone and red warning lamp :flashes. If the turn
signal remains on, detected vehicles are indica-
ted by the flashing of red warning lamp :.
There are no further warning tones.
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. 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 on the exterior mir-
ror and a double warning tone sounds. In addi-
tion, a display underlining the danger of a side
collision appears on 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 by countersteering slightly or acceler-
ating.
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 vehicles or obstacles, e.g. crash barriers, are
located on 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 a loss of tyre pressure or a defective tyre is
detected

Lane-correcting brake application
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. G
WARNING
A lane-correcting brake application cannot
always bring the vehicle back into the original lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes a lane-correcting brake appli-
cation. If a lane-correcting brake application occurs,
display :appears on the multifunction display.
The brake application also slightly reduces driv- ing speed.
A lane-correcting brake application can be made
after the car has passed over a lane marking
detected as being solid or broken. Before this, a warning must have been issued by means of
intermittent vibration through the steering
wheel. In addition, 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 be made only if a vehicle has been detected
in the adjacent lane. Oncoming vehicles, over-
taking vehicles and vehicles in adjacent lanes
can be detected.
A further lane-correcting brake application can
occur only after your vehicle has returned to the original lane.
No lane-correcting brake application occurs in
the following situations:
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 engages, such as
ESP ®
, PRE-SAFE ®
Brake or Active Blind Spot

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 a loss of tyre pressure or a defective tyre has
been detected and displayed
R an obstacle has been detected in the lane in
which you are driving
Active Lane Keeping Assist may not detect other road users or traffic situations. An inappropriate
brake application may be interrupted at any time
in the following situations:
R you steer slightly in the opposite direction
R you switch on the turn signal
R you brake or accelerate significantly
A lane-correcting brake application is interrup-
ted automatically in the following situations:
R a driving safety system engages, such as

Important safety notes
G
WARNING
You could lose control of the vehicle/trailer
combination if it begins to swerve. The vehi-
cle/trailer combination could even overturn.
There is a risk of an accident.
On no account should you attempt to
straighten out the vehicle/trailer combina-
tion by increasing speed. Decrease your
speed and do not countersteer. Brake if nec-
essary. G
WARNING
If the maximum permissible load for a carrier system is exceeded, the carrier could come
loose from the vehicle and endanger other
road users. There is a risk of an accident and injury.
Never exceed the maximum permissible load
when using a carrier.
! If you have a trailer tow hitch retrofitted,
changes to the engine cooling system may be necessary, depending on the vehicle type.
If you have a trailer tow hitch retrofitted,
observe the anchorage points on the chassis.
Retrofitting a trailer tow hitch is only permissible
if a trailer load is specified in your vehicle docu-
ments. If this is not the case, then the vehicle is not approved for towing a trailer.
For more information, please contact a qualifiedspecialist workshop.
Exceeding the maximum permissible nose-
weight of the trailer drawbar on the ball coupling
may cause damage.
Damage may be caused to the following:

Towing a trailerDriving and parking

This will use the braking effect of the engine, so
less braking will be required to maintain the
vehicle speed. This relieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly. If you need additional braking, depress the brake pedal
repeatedly rather than continuously.
Driving tips R
Maintain a greater distance to the vehicle in
front than when driving without a trailer.
R Avoid braking abruptly. If possible, brake gen-
tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
R The values given for gradient-climbing capa-
bilities from a standstill refer to sea level.
When driving in mountainous areas, note that
the power output of the engine, and conse-
quently the vehicle's gradient-climbing capa-
bility from a standstill, decrease with increas- ing altitude.
If the trailer swings from side to side:
X Do not accelerate under any circumstances.
X Do not countersteer.
X Brake, if necessary. Swivelling the ball coupling in/out
Important safety notes G
WARNING
If the ball coupling is not engaged, the trailer
may come loose. There is a risk of an accident.
Make sure that the ball coupling is securely
engaged and locked in position.
! Do not attempt to speed the up the swing-
out procedure by applying additional pressure
with your foot. The system could otherwise be
mechanically damaged.
