sensor MERCEDES-BENZ GLE 2018 Owner's Manual

The cornering light function is activated on both
sides before entering a traffic circle through an
evaluation of the current GPS position of the
vehicle. It remains active until after the vehicle
has left the traffic circle. In this way, pedestrians
crossing the road, for example, are illuminated
by your vehicle in good time.
Highway mode Highway mode increases the range of the beam.
Active: if you are driving at a speed above
110 km/h and do not make any large steering
movements for at least 1,000 m or if you are
driving at a speed above 130 km/h.
Not active: if you are driving at speeds below
80 km/h following activation.
Extended range fog lamps The extended range fog lamps reduce the glare
experienced by the driver and improve the illu-
mination of the edge of the road.
Active: if you are driving at speeds below
40 mph (70 km/ h) and you switch on the rear
fog lamp.
Not active: if, following activation, you are driv-
ing at speeds above 60 mph (10 0 km/ h) or if you
switch off the rear fog lamp
Off-road lights The off-road lights facilitate the early recogni-
tion of objects/obstacles when driving off-road
thanks to a symmetrical, wider and brighter dis-
tribution of light from the low-beam headlamps.
Active: when driving at speeds no faster than
30 mph (50 km/h) and the off-road program
selector wheel is in position 1 or 2.
Not active: when driving at speeds above
30 mph (50 km/h).
When the off-road lights are switched on, the
cornering light function is permanently activa-
ted, the active light function is deactivated and
the headlamp range control is set to static
mode. Adaptive Highbeam Assist
General notes You can use this function to set the headlamps
to change between low beam and high beam
automatically. The system recognizes vehicles
with their lights on, either approaching from the
opposite direction or traveling in front of your
vehicle, and consequently switches the head-
lamps from high beam to low beam.
The system automatically adapts the low-beam
headlamp range depending on the distance to
the other vehicle. Once the system no longer
detects any other vehicles, it reactivates the
high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control panel.
Important safety notes
G WARNING
Adaptive Highbeam Assist does not recognize
road users: R
who have no lights, e.g. pedestrians R
who have poor lighting, e.g. cyclists R
whose lighting is blocked, e.g. by a barrier
On very rare occasions, Adaptive Highbeam
Assist may fail to recognize other road users
that have lights, or may recognize them too
late. In this, or in similar situations, the auto-
matic high-beam headlamps will not be deac-
tivated or will be activated regardless. There is
a risk of an accident.
Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist is only an aid. You are
responsible for adjusting the vehicle's lighting
to the prevailing light, visibility and traffic con-
ditions.
In particular, the detection of obstacles can be
impaired if: R
poor visibility, e.g. due to fog, heavy rain or
snow R
dirt on the sensors or the sensors are
obscuredExterior lighting 113

Notes on breaking-in a new vehicle
Important safety notes The sensor system of some driving and driving
safety systems adjusts automatically while a
certain distance is being driven after the vehicle
has been delivered or after repairs. Full system
effectiveness is not reached until the end of this
teach-in procedure.
New and replaced brake pads and discs only
reach their optimum braking effect after several
hundred kilometers of driving. Compensate for
this by applying greater force to the brake pedal.
The first 1000 miles (1500 km) The more you look after the engine when it is
new, the more satisfied you will be with its per-
formance in the future. R
You should therefore drive at varying vehicle
and engine speeds for the first 1000 miles
(1500 km). R
Avoid heavy loads, e.g. driving at full throttle,
during this period. R
Change gear in good time, before the tach-
ometer needle is

i When you switch off the engine, the last
speed stored is cleared.
Distance Pilot DISTRONIC
General notes Distance Pilot DISTRONIC regulates the speed
and automatically helps you maintain the dis-
tance to the vehicle detected in front. Vehicles
are detected with the aid of the radar sensor
system. Distance Pilot DISTRONIC brakes auto-
matically so that the set speed is not exceeded.
You must select a lower gear in good time on
long and steep downhill gradients, especially if
the vehicle is laden or towing a trailer. By doing
so, you will make use of the braking effect of the
engine. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
If Distance Pilot DISTRONIC detects that there is
a risk of a collision, you will be warned visually
and acoustically. Without your intervention, Dis-
tance Pilot DISTRONIC cannot prevent a colli-
sion. An intermittent warning tone will then
sound and the distance warning lamp will light
up in the instrument cluster. Brake immediately
in order to increase the distance to the vehicle in front or take evasive action provided it is safe to
do so.
For Distance Pilot DISTRONIC to assist you
when driving, the radar sensor system must be
operational.
Distance Pilot DISTRONIC ope rates in the range
b etween 0 mph (0 km/h) and 120 mph
(200 km/h).
Do not use Distance Pilot DISTRONIC while driv-
ing on roads with steep gradients.
Since Distance Pilot DISTRONIC transmits radar
waves, it can resemble the radar detectors of
the responsible authorities. You can refer to the
relevant chapter in the Operator's Manual if
questions are asked about this.

As a result, Distance Pilot DISTRONIC may
neither give warnings nor intervene in such
situations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
G WARNING
Distance Pilot DISTRONIC cannot always
clearly identify other road users and complex
traffic situations.
In such cases, Distance Pilot DISTRONIC may: R
give an unnecessary warning and then
brake the vehicle R
neither give a warning nor intervene R
accelerate or brake unexpectedly
There is a risk of an accident.
Continue to drive carefully and be ready to
brake, especially if Distance Pilot DISTRONIC
warns you.
G WARNING
Distance Pilot DISTRONIC brakes your vehicle
with up to 50% of the maximum possible
deceleration. If this deceleration is not suffi-
cient, Distance Pilot DISTRONIC alerts you
with a visual and acoustic warning. There is a
risk of an accident.
Apply the brakes yourself in these situations
and try to take evasive action.
! When Distance Pilot DISTRONIC or the
HOLD function is activated, the vehicle
brakes automatically in certain situations.
To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or similar situations: R
when towing the vehicle R
in the car wash
The Distance Pilot DISTRONIC R
can neither reduce the risk of accident nor
override the laws of physics if you fail to adapt
your driving style. R
cannot take into account road, weather or
traffic conditions. R
is only an aid. You are responsible for the dis-
tance to the vehicle in front, for vehicle speed, for braking in good time and for staying in your
lane.
Do not use Distance Pilot DISTRONIC: R
in road and traffic conditions which do not
allow you to maintain a constant speed, e.g. in
heavy traffic or on winding roads R
on slippery road surfaces. Braking or accel-
erati ng could cause the drive wheels to lose
tra ction and the vehicle could then skid R
in poor visibility, e.g. due to fog, heavy rain or
snow
Distance Pilot DISTRONIC may not detect nar-
row vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line.
In particular, the detection of obstacles can be
impaired if: R
there is dirt on the sensors or anything else
covering the sensors R
there is snow or heavy rain R
there is interference by other radar sources R
there are strong radar reflections, for exam-
ple, in parking garages
If Distance Pilot DISTRONIC no longer detects a
vehicle in front, it may unexpectedly accelerate
to the speed stored.
This speed may: R
be too high if you are driving in a turning lane
or an exit lane R
be so high when driving in the right-hand lane
that you overtake vehicles in the left-hand
lane R
be so high when driving in the left-hand lane
that you overtake vehicles in the right-hand

Course-correcting brake application If Active Blind Spot Assist detects a risk of a lat-
eral collision in the monitoring range, a course-
correcting brake application is carried out. This
is meant to assist you in avoiding 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 C flashes in the exterior mir-
ror and a double warning tone sounds. In addi-
tion, a 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 by countersteering slightly or acceler-
ating.
The course-correcting brake application is avail-
able in the speed range between 20 mph
(30 km/h) and 120 mph (20 0 km/ h) .
Either no braking application, or a course-cor-
recting brake application adapted to the driving
situation occurs if: R
there are vehicles or obstacles, e.g. crash
barriers, located on both sides of your vehicle. R
a vehicle approaches you too closely at the
side. R
you have adopted a sporty driving style with
high cornering speeds. R
you clearly brake or accelerate. R

Active Lane Keeping Assist
General notes
Active Lane Keeping Assist monitors the area in
front of your vehicle by means of multifunction
camera C at the top of the windshield. 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, a210

lane-correcting application of the brakes can
bring the vehicle back into the original lane.
This function is available in a speed range
between 40 mph and 120 mph (60 km/h and
200 km/h).
For Active Lane Keeping Assist to assist you
when driving, the radar sensor system must be
operational.
Important safety notes If you fail to adapt your driving style, Active Lane
Keeping Assist can neither reduce the risk of
accident nor override the laws of physics. Active
Lane Keeping Assist cannot take into account
road, weather or traffic conditions. Active Lane
Keeping Assist is only an aid. You are responsi-
ble for the distance to the vehicle in front, for
vehicle speed, for braking in good time and for
staying in your lane.
Active Lane Keeping Assist cannot continuously
keep your vehicle in its lane.
G WARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can: R
give an unnecessary warning and then
make a course-correcting brake application
to the vehicle R
not give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you. Ter-
minate the intervention in a non-critical driv-
ing situation.
The system may be impaired or may not function
if: R
there is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or heavy spray R
there is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road surface is wet) R
the windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera R
there are no or several unclear lane markings
for one lane, e.g. roadworks 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 too short
and thus the lane markings cannot be detec-
ted R
the lane markings change quickly, e.g. lanes
branch off, cross one another or merge R
the road is narrow and winding R
there are highly variable shade conditions on
the roadway R
no vehicle is detected in the adjacent lane and
there are broken lane markings
Warning vibration in the steering wheel A warning may be given if a front wheel passes
over a lane marking. It will warn you by mean s of
intermittent vibration in the steering wheel for
up to 1.5 seconds.
In order that you are warned only when neces-
sary and in good time if you cross the lane mark-
ing, the system detects certain conditions and
warns you accordingly.
The warning vibration occurs earlier if: R
you approach the outer lane marking on a
bend R
the road has very wide lanes, e.g. a freeway R
the system detects solid lane markings
The warning vibration occurs later if: R
the road has narrow lanes R
you cut the corner on a bend
