2019 MERCEDES-BENZ GLE lane assist

Hilltops
When driving up an uphill gradient, slightly
reduce pressure on the accelerator immediately
before reaching the brow of the hill. Make use of the vehicle's own impetus to travel over the
brow.
This style of driving prevents:
R the vehicle from lifting off the ground on the
brow of a hill
R the vehicle from traveling too quickly down
the other side
Driving downhill R
Drive slowly.
R Do not drive at an angle down steep inclines.
Steer into the line of fall and drive with the
front wheels aligned straight. Otherwise, the
vehicle could slip sideways, tip and rollover.
R Shift to a lower gear using the left-hand pad-
dle shifter before tackling steep downhill gra-
dients.
R Activate DSR. If this is not sufficient, brake
gently. When doing so, make sure that the
vehicle is facing in the direction of the line of
fall.
R Check that the brakes are working normally
after a long downhill stretch.
i The special off-road ABS setting enables a
precise, brief and repeated locking of the
front wheels. This causes them to dig into
loose earth. Be aware that the front wheels
easily skid across the ground surface if com-
pletely braked and therefore lose their ability
to steer. Driving systems
Intelligent Drive
Mercedes-Benz Intelligent Drive stands for inno-
vative driver assistance and safety systems
which enhance comfort and support the driver in critical situations. With these intelligent co-ordi-
nated systems Mercedes-Benz has set a mile-
stone on the path towards autonomous driving.
Mercedes-Benz Intelligent Drive embraces all
elements of active and passive safety in one well
thought out system – for the safety of the vehi-
cle occupants and that of other road users. Further information on driving safety systems
(Y
page 66). Cruise control
General notes Cruise control maintains a constant road speed
for you. It brakes automatically in order to avoid
exceeding the set speed. You must select a
lower gear in good time on long and steep down-
hill 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 system and prevents the
brakes from overheating and wearing too
quickly.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a steady speed for a prolonged period. You can store anyroad speed above 20 mph (30 km/h).
i Cruise control should not be activated when
driving off-road.
Important safety notes If you fail to adapt your driving style, cruise con-
trol can neither reduce the risk of an accident
nor override the laws of physics. Cruise control
cannot take into account the road, traffic and
weather conditions. Cruise control 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 your lane.
Do not use cruise control:
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-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
If there is a change of drivers, advise the new
driver of the speed stored. Driving systems

Important safety notes
G
WARNING
Active Distance Assist DISTRONIC does not
react to:
R people or animals
R stationary objects in the road, e.g. stopped
or parked vehicles
R oncoming vehicles and crossing traffic
As a result, Active Distance Assist 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
Active Distance Assist DISTRONIC cannot
always clearly identify other road users and
complex traffic situations.
In such cases, Active Distance Assist
DISTRONIC can:
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 Active Distance Assist
DISTRONIC warns you. G
WARNING
Active Distance Assist DISTRONIC brakes
your vehicle with up to 50% of the maximum
possible deceleration. If this deceleration is
not sufficient, Active Distance Assist
DISTRONIC alerts you with a visual and acous- tic warning. There is a risk of an accident.
Adjust your speed in these cases and main-
tain sufficient distance.
Apply the brakes yourself and/or take evasive
action.
! When Active Distance Assist DISTRONIC or
the HOLD function is activated, the vehicle
brakes automatically in certain situations. To avoid damage to the vehicle, deactivate
Active Distance Assist DISTRONIC and the
HOLD function in the following or similar sit-
uations:
R when towing the vehicle
R in the car wash
Active Distance Assist 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 distance to the vehi-
cle in front, for vehicle speed, for braking in good
time and for staying in your lane.
Do not use Active Distance Assist 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 icy or slippery roads; braking or acceler-
ating can cause the drive wheels to lose trac-
tion and the vehicle could then skid
R In poor visibility, e.g. due to fog, heavy rain or
snow
Active Distance Assist DISTRONIC may not
detect narrow vehicles driving in front, e.g.
motorcycles, or vehicles driving in a staggered
formation.
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 Active Distance Assist DISTRONIC no longer
detects a vehicle in front, Distance Pilot
DISTRONIC 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 in the left lane that you pass vehi-
cles driving on the right 172

Driving with Active Distance Assist
DISTRONIC Pulling away and driving
X If you want to pull away with Active Dis-
tance Assist DISTRONIC: remove your foot
from the brake pedal.
X Briefly pull the cruise control lever towards
you 0085.
or
X Accelerate briefly.
Your vehicle pulls away and adapts its speed
to that of the vehicle in front. If no vehicle is
detected in front, your vehicle accelerates to
the set speed.
The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on a differ-
ent line from another vehicle. The vehicle then
brakes automatically.
If there is no vehicle in front, Active Distance
Assist DISTRONIC operates in the same way as cruise control.
If Active Distance Assist DISTRONIC detects a
slower-moving vehicle in front, it brakes your
vehicle. In this way, the distance you have selec-
ted is maintained.
If Active Distance Assist DISTRONIC detects a
faster-moving vehicle in front, it increases the
driving speed. However, the vehicle is only
accelerated up to the speed you have stored.
Selecting the drive programActive Distance Assist DISTRONIC supports a
sporty driving style if you have selected the
Sport orSport Plus drive program
(Y page 146). Acceleration behind the vehicle in
front or to the set speed is then noticeably more
dynamic. If you have selected the Comfortdrive
program, the vehicle accelerates more gently.
This setting is recommended in stop-and-start
traffic.
Changing lanes If you change to the overtaking lane, Active Dis-
tance Assist DISTRONIC helps you if:
R you are driving faster than 45 mph (70 km/h)
R you switch on the appropriate turn signal
R Active Distance Assist DISTRONIC does not
currently detect a danger of collision
If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted if
changing lanes takes too long or if the distance between your vehicle and the vehicle in front
becomes too small.
i When you change lanes, Active Distance
Assist DISTRONIC monitors the right lane (in
left-side traffic) or the left lane (in right-side
traffic).
Stopping G
WARNING
If you leave the driver's seat when the vehicle is only being braked by Active Distance Assist
DISTRONIC, it could roll away:
R if there is a malfunction in the system or in
the voltage supply
R if Active Distance Assist DISTRONIC is
deactivated using the cruise control lever,
for example by a vehicle occupant or from
outside the vehicle
R if the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with
R if the battery is disconnected
R if the vehicle is accelerated, e.g. by a vehi-
cle occupant
There is a risk of an accident.
Always deactivate Active Distance Assist
DISTRONIC and secure the vehicle against
rolling away before you leave it.
If Active Distance Assist DISTRONIC detects
that the vehicle in front is stopping, it brakes
your vehicle until it is stationary.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
After a time, the electric parking brake secures
the vehicle and relieves the service brake.
Depending on the specified minimum distance,
your vehicle will come to a standstill at a suffi-
cient distance behind the vehicle in front. The
specified minimum distance is set using the
control on the cruise control lever. 174

Tips for driving with Active Distance
Assist DISTRONIC General notes
Pay particular attention in the following traffic
situations:
R Cornering, entering and exiting a bend: the
ability of Active Distance Assist DISTRONIC to detect vehicles on bends is limited. Your vehi-cle may brake unexpectedly or late.
R Vehicles driving in a staggered formation:
Active Distance Assist DISTRONIC may not
detect vehicles that are not driving in the mid- dle of their lanes. The distance to the vehiclein front will be too short.
R Other vehicles changing lane: Active Distance
Assist DISTRONIC has not detected the vehi-
cle cutting in yet. The distance to this vehicle
will be too short.
R Narrow vehicles: Active Distance Assist
DISTRONIC has not yet detected the vehicle
in front on the edge of the road because of its
narrow width. The distance to the vehicle in
front will be too short.
R Obstacles and stationary vehicles: Active Dis-
tance Assist DISTRONIC does not brake for obstacles or stationary vehicles. If, for exam-
ple, the detected vehicle turns a corner and
an obstacle or stationary vehicle is revealed,
Active Distance Assist DISTRONIC will not
brake for them.
R Crossing vehicles: Active Distance Assist
DISTRONIC may mistakenly detect vehicles
that are crossing your lane. Activating Active
Distance Assist DISTRONIC at, for example, a
traffic light with crossing traffic could cause
your vehicle to pull away at the wrong time.
In such situations, brake if necessary. Active
Distance Assist DISTRONIC will then be deacti-
vated.
Active Distance Assist DISTRONIC with
Active Steering Assist General notes
Active Distance Assist DISTRONIC with Active
Steering Assist aids you in keeping the vehicle in
the center of the driving lane by means of mod-
erate steering interventions in a speed range
from 0 - 125 mph (0 - 200 km/h).
It monitors the area in front of your vehicle by
means of camera system 0043at the top of the
windshield.
In a speed range from 0 - 37 mph (0 - 60 km/h),
the advanced automatic pulling away function
focuses on the vehicle in front, taking into
account lane markings, e.g. when following vehi-
cles in a traffic jam.
At speeds of more than 37 mph (60 km/h),
Active Steering Assist focuses on clear lane
markings (left and right), focusing on the vehicle
in front only if clear lane markings are not pres-
ent.
If these conditions are not present, Active Steer-
ing Assist cannot provide assistance. Driving systems

Important safety notes
Active Distance Assist DISTRONIC with Active
Steering Assist can neither reduce the risk of an accident if you fail to adapt your driving style,
nor override the laws of physics. It cannot take
into account road, weather or traffic conditions.Active Distance Assist DISTRONIC with Active
Steering 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 Distance Assist DISTRONIC with Active
Steering Assist does not detect road and traffic conditions and does not detect all road users. If
you are following a vehicle which is driving
towards the edge of the road, your vehicle could
come into contact with the curb or other road
boundaries. Be particularly aware of other road
users, e.g. cyclists, that are directly next to your vehicle.
Obstacles such as traffic pylons on the lane or
projecting out into the lane are not detected.
An inappropriate steering intervention, e.g. after
intentionally driving over a lane marking, can be
corrected at any time if you steer slightly in the opposite direction.
Active Distance Assist DISTRONIC with Active
Steering Assist cannot continuously keep your
vehicle in lane. In some cases, the steering
intervention is not sufficient to bring the vehicleback to the lane. In such cases, you must steer
the vehicle yourself to ensure that it does not
leave the lane.
The support provided by the system can be
impaired 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
The system is switched to passive and no longer assists you by performing steering interventions
if:
R you actively change lane
R you switch on the turn signal
R you take your hands off the steering wheel or
do not steer for a prolonged period of time
i Once you have finished changing lanes,
Active Steering Assist automatically reacti-
vates.
Active Steering Assist cannot provide assis-
tance: R on very sharp corners
R when towing a trailer
R when a loss of tire pressure or a defective tire
has been detected and displayed
Observe the important safety notes on Active
Distance Assist DISTRONIC (Y page 172).
The steering interventions are carried out with a limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with
a visual warning. A steering wheel symbol
appears in the multifunction display. If you have still not started to steer and have not taken hold
of the steering wheel after five seconds at the
latest, a warning tone also sounds to remind you
to take control of the vehicle. Active Steering
Assist is then switched to passive. Active Dis-
tance Assist DISTRONIC remains active.

General notes Active Parking Assist is an electronic parking aid
with ultrasound. It measures the road on both
sides of the vehicle. A parking symbol indicates a suitable parking space. Active steering inter-
vention and brake application can assist you
during parking. Parking Assist PARKTRONIC is
also available (Y page 188).
Important safety notes Active Parking Assist is merely an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering, parking and exiting a
parking space. Make sure that no persons, ani-
mals or objects are in the path of your vehicle.
When Parking Assist PARKTRONIC is deactiva-
ted, Active Parking Assist is also unavailable. G
WARNING
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 or
objects. There is a risk of an accident.
Pay attention to other road users or objects.
Stop the vehicle if necessary or cancel the
Active Parking Assist parking procedure.
! If they cannot be avoided, drive over obsta-
cles such as curbs slowly and at an obtuse
angle. Otherwise, you may damage the
wheels or tires.
Active Parking Assist may also show parking
spaces that are not suitable for parking, e.g.: R where parking or stopping is prohibited
R in front of driveways or entrances and exits
R on unsuitable surfaces Driving systems
