–When a sign or mirror-like surface is
reflecting intense light towards the
front of the vehicle.
– When the container, etc. being towed
by a leading vehicle is reflecting in-
tense light.
– When a headlight on your vehicle is
damaged or dirty.
– When the vehicle is leaning at an
angle due to a punctured tire, being
towed, etc.
•The timing of switching the low beam
and high beam may change under the
following situations. –
The brightness of the headlights of the
oncoming vehicle or leading vehicle.
–The movement and direction of the on-
coming vehicle and the leading vehicle.
– When only one light on the oncoming
vehicle or the leading vehicle is illumi-
nated.
–
When the oncoming vehicle or the lead-
ing vehicle is a two-wheeled vehicle.
– Road conditions (incline, curve, the
road surface, etc.).
– The number of passengers and the
amount of luggage.
•High beam Assist does not recognize
road users: – Who have no lights, e.g. pedestrians. –
Who have low intensity lighting, e. g.
cyclists.
– Whose lighting is blocked, e.g. by a
barrier.
•In very rare cases, High beam Assist rec-
ognizes road users too late or not at all.
In this, or in similar situations, the auto-
matic high beam headlights will not be
deactivated or activated regardless.
There is a risk of an accident.
•Always carefully observe the traffic
conditions and switch off the high beam
headlights in good time.
CAUTION
High beam Assist cannot compensate for
road and weather circumstances while
driving. The system saves the driver from
having to operate the switch. The driver
always remains responsible for choosing
the correct light setting.
Specific situations in which to operate the
headlight switch manually:
•In heavy rain, snowy conditions. (gen-
eral poor visibility and bad weather con-
ditions).
•When the vehicle sensors are dirty, cov-
ered or broken.
Switching High Beam Assist on/off
To switch on:
Turn the light switch to
the combination switch beyond the pressure
point in the direction of arrow
3. Theindicator light in the vehicle information dis-
play lights up when it is dark and the light
sensor switches on the low-beam headlights.
If you are driving at speeds above approxi-
mately 28 MPH (45 km/h) the headlight
range is set automatically depending on the
distance between the vehicle and other road
users.
If you are driving at speeds above approxi-
mately 34 MPH (55 km/h) and no other road
users are detected, the high beam headlights
are switched on automatically. The

FEB SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the FEB system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious injury or
death.
•The FEB system cannot detect all ve-
hicles under all conditions.
•The radar sensor does not detect the
following objects: – Pedestrians or animals
– Oncoming vehicles
– Crossing vehicles
•The radar sensor has some performance
limitations. For stationary vehicles, the
FEB system will not function when the
vehicle is driven at speeds over: –
Approximately 31 MPH (50 km/h) for
the Autonomous braking function.
•The radar sensor may not detect a ve-
hicle ahead in the following conditions: – Dirt, ice, snow or other material cov-
ering the radar sensor. –
Interference by other radar sources.
– Snow or heavy rain.
– If the vehicle ahead is narrow (e.g.
motorcycle).
– If the vehicle ahead is in a different
lane.
– Under strong radar reflections, for
example, in a multi-level parking ga-
rage.
– New vehicle or after a maintenance
of the FEB system. For additional in-
formation, see "Break-in schedule"
later in this section
– When driving on a steep downhill
slope or roads with sharp curves.
– When towing a trailer.
•In some road or traffic conditions, the
FEB system may intervene unnecessar-
ily or give an unnecessary warning. Al-
ways pay careful attention to the traffic
situation. Do not rely solely on the dis-
tance warning function and terminate
the intervention if necessary.
•Braking distances increase on slippery
surfaces.

IPA is an electronic parking aid with ultra-
sound. It detects vehicles and open spaces on
both sides of the vehicle. A parking symbol
indicates a suitable parking space. Active
steering intervention can assist you during
parking and when exiting a parking space.
The driver controls the accelerator, brake and
gear shift. You may also use the Camera Aid-
ing Sonar (parking sensor) function (see "
Camera Aiding Sonar (parking sensor) func-
tion (if equipped)" later in this section).
IMPORTANT SAFETY NOTES
WARNING
•IPA is only an aid. It is not a substitute
for your attention to the immediate sur-
roundings. The responsibility for safe
maneuvering and parking remains with
you.
•Make sure that no persons, animals or
objects are in the maneuvering range
•When the sonar (parking sensor) func-
tion is deactivated, IPA is also unavail-
able.
•While parking or pulling out of a parking
space, the vehicle swings out and can
drive onto areas of the oncoming lane.
This could cause you to collide with other road users. There is a risk of an
accident.
•Pay attention to other road users. Stop
the vehicle if necessary or cancel the IPA
parking procedure
•This system is not designed to prevent
contact with small or moving objects.
•If your vehicle sustains damage to the
bumper fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of ob-
stacles or false alarms.
•This system is not designed to prevent
contact with small or moving objects.
•If your vehicle sustains damage to the
bumper fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of ob-
stacles or false alarms.
CAUTION
Do not drive over obstacles such as curbs,
as you may damage the wheels or tires.
IPA may also display spaces not suitable for
parking, for example:
•Parking or stopping prohibition.
•In front of driveways or entrances and
exits.
•Unsuitable surfaces.
Parking tips:
•On narrow roads, drive as closely as pos-
sible past the parking space.
•Parking spaces that are littered or over-
grown might be identified or measured
incorrectly.
•Parking spaces that are partly occupied by
trailer towing bars might not be identified
as such or be measured incorrectly.
•Snowfall or heavy rain may lead to a park-
ing space being measured inaccurately.
•Pay attention to the sonar function warn-
ing messages during the parking proce-
dure.
•You can intervene in the steering proce-
dure to correct it at any time. IPA will then
be canceled.
•When transporting a load which protrudes
from your vehicle, you should not use IPA.
•Never use IPA when snow chains are fit-
ted.
•Make sure that the tire pressures are al-
ways correct. This has a direct influence on
the parking characteristics of the vehicle.
INTELLIGENT PARKING ASSIST (IPA)
(IF EQUIPPED)
Starting and driving5-71
Use IPA for parking spaces that are:
•Parallel or at right angles to the direction
of travel.
•On straight roads, not bends.
•On the same level as the road, e. g. not on
the sidewalk.
For vehicles with the towbar folded out, the
minimum length for parking spaces is slightly
longer.
If you have attached a trailer to your vehicle,
you may not use IPA. Once the electrical
connection is established between your ve-
hicle and the trailer, IPA is no longer available.
The sonar function is deactivated for the rear
area
DETECTING PARKING SPACES
The IPA system can only be used to park in
spaces that have vehicles directly on either
side of the parking space.
Objects located above the height range of
IPA will not be detected when the parking
space is measured. These are not taken into
account when the parking procedure is calcu-
lated, e. g. overhanging loads, tail sections or
loading ramps of goods vehicles.
WARNING
If there are objects above the detection
range, IPA may steer too early. This could
cause a collision. There is a risk of an acci-
dent.
If objects are located above the detection
range, stop and switch off the IPA.
For further information on the detection
range see "Range of the sensors" later in this
section.
IPA does not assist you parking in spaces at
right angles to the direction of travel if:
•Two parking spaces are located directly
next to one another.
•The parking space is directly next to a low
obstacle such as a low curb.
•You forward park.
IPA does not assist you parking in spaces that
are parallel or at right angles to the direction
of travel if:
•The parking space is on a curb.
•The system reads the parking space as
being blocked, for example, by foliage or
grass paving blocks.
•The area is too small for the vehicle to
maneuver into.
•The parking space is bordered by an ob-
stacle, e.g. a tree, a post or a trailer.
