2016 MERCEDES-BENZ GL cruise control

press the cruise control lever up C or
down D to the pressure point.
Every time the cruise control lever is
pressed up C or down D the last speed
stored is increased or reduced.
i Cruise control is not deactivated if you
depress the accelerator pedal. For exam-
ple, if you accelerate briefly to overtake,
cruise control adjusts the vehicle's speed
to the last speed stored after you have fin-
ished overtaking.
Deactivating cruise control
There are several ways to deactivate cruise
control: X
Briefly press the cruise control lever for-
wards C .
or X
Brake.
Cruise control is automatically deactivated if: R
you engage the electric parking brake R
you are driving at less than 20 mph
(30 km/h) R
ESP ®
intervenes or you deactivate ESP ®
R
you activate DSR R
you activate off-road program 2 on vehicles
with the ON&OFFROAD package R
you shift the transmission to position N
while driving
If cruise control is deactivated, you will hear a
warning tone. You will see the Cruise Con‐
trol Off message in the multifunction dis-
play for approximately five seconds. i When you switch off the engine, the last
speed stored is cleared.
DISTRONIC PLUS
General notes DISTRONIC PLUS regulates the speed and
automatically helps you maintain the dis-
tance to the vehicle detected in front. Vehi-
cles are detected with the aid of the radar
sensor system. DISTRONIC PLUS brakes
automatically 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 system and prevents the brakes
from overheating and wearing too quickly.
If DISTRONIC PLUS detects that there is a risk
of a collision, you will be warned visually and
acoustically. DISTRONIC PLUS cannot pre-
vent a collision without your intervention. 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 DISTRONIC PLUS to assist you, the radar
sensor system must be operational.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control in the speed range between 20 mph
(Canada: 30 km/h) and 120 mph (Canada:
200 km/ h) . If a vehicle is driving in front of
you, it operates in the speed range between
0 mph (0 km/h) and 120 mph (Canada:
200 km/h).
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTRONIC PLUS transmits radar waves, it
can resemble the radar detectors of the
responsible authorities. You can refer to the Driving systems 205
Driving and parking Z

Do not use DISTRONIC PLUS: 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
DISTRONIC PLUS may not detect narrow
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
example, in parking garages
If DISTRONIC PLUS no longer detects a vehi-
cle in front, DISTRONIC PLUS may unexpect-
edly accelerate the vehicle to the stored
speed.
This speed may: R
be too high if you are driving in a filter 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
lane
If there is a change of drivers, advise the new
driver of the speed stored. Cruise control lever

To activate or reduce speed

Activating X
Briefly pull the cruise control lever towards
you

However, the vehicle is only accelerated up to
the speed you have stored.
If you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary.
Changing lanes
If you change to the passing lane, DISTRONIC
PLUS supports you when: R
you are driving faster than 40 mph
(60 km/h) R
DISTRONIC PLUS is maintaining the dis-
tance to a vehicle in front R
you switch on the appropriate turn signal R
DISTRONIC PLUS does not 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 dis-
tance between your vehicle and the vehicle in
front becomes too small.
i When you change lanes, DISTRONIC
PLUS monitors the left lane on left-hand-
drive vehicles or the right lane on right-
hand-drive vehicles.
Stopping
G WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if: R
there is a malfunction in the system or in
the voltage supply. R
DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle. R
the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with. R
the battery is disconnected. R
the accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away. If DISTRONIC PLUS detects that the vehicle in
front is stopping, it brakes your vehicle until it
is stationary.
Once your vehicle is stationary, it remains
stationary 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 dis-
tance, your vehicle will come to a standstill at
a sufficient distance behind the vehicle in
front. The specified minimum distance is set
using the control on the cruise control lever.
The electric parking brake automatically
secures the vehicle if DISTRONIC PLUS is
activated and: R
the driver's door is open and the driver's
seat belt is unfastened. R
the engine is switched off, unless it is auto-
matically switched off by the ECO start/
stop function. R
a system malfunction occurs. R
the power supply is not sufficient.
On stee p uphill or downhill inclines or if there
is a malfunction, the transmission may also
automatically be shifted into position P .
Setting a speed
Keep in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the speed set. Driving systems 209

This could impair the handling characteris-
tics.
When towing a trailer, always adjust your
speed to the current road and weather con-
ditions. Do not exceed the maximum permis-
sible speed for your vehicle/trailer combina-
tion.
Notes on towing a trailer
General notes The following models cannot be used to tow a
trailer: R
GLE 550 e 4MATIC Sport Utility Vehicle R
Do not exceed the legally prescribed max-
imum speed for vehicle/trailer combina-
tions in the relevant country.
This lowers the risk of an accident. R
Only install an approved trailer coupling on
your vehicle.
Further information on availability and on
installation is available from any authorized
Mercedes-Benz Center. R
The bumpers of your vehicle are not suita-
ble for installing detachable trailer cou-
plings. R
Do not install hired trailer couplings or
other detachable trailer couplings on the
bumpers of your vehicle. R
If you no longer need the ball coupling,
remove it from the ball coupling recess.
This will reduce the risk of damage to the
ball coupling.
When towing a trailer, set the tire pressure on
the rear axle of the towing vehicle for the
maximum load. You will find the values in the
tire pressure table in the fuel filler flap of the
vehicle ( Y
page 425).
Please note that when towing a trailer, the
following driving systems have limited avail-
ability or are not available at all: R
PARKTRONIC ( Y
page 224)R
Blind Spot Assist ( Y
page 244)R
Active Lane Keeping Assist ( Y
page 251) You will find installing dimensions and loads
under "Technical data" ( Y
page 457).
Driving tips Observe the information on ESP ®
trailer sta-
bilization ( Y
page 75) and on pulling away with
a trailer ( Y
page 168).
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check
the trailer's documents to see what the max-
imum permissible speed is. Observe the
legally prescribed maximum speed in the rel-
evant country.
For certain Mercedes-Benz vehicles, the max-
imum permissible rear axle load is increased
when towing a trailer. See "Technical data" to
find out whether this applies to your vehicle
( Y
page 458). If you utilize any of the added
maximum rear axle load when towing a trailer,
the vehicle/trailer combination may not
exceed a maximum speed of 60 mph
(100 km/h) for reasons concerning the oper-
ating permit. This also applies in countries in
which the permissible maximum speed for
vehicle/trailer combinations is above 60 mph
(100 km/ h) .
When towing a trailer, your vehicle's handling
characteristics will be different in comparison
with when driving without a trailer.
Use the left-hand steering wheel paddle
shifter to shift into a lower gear in good time
on long and steep downhill gradients.
This also applies if you have activated cruise
control or DISTRONIC PLUS.
This will use the braking effect of the engine,
so that less braking will be required to main-
tain the 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.264
