2016 MERCEDES-BENZ GL service

R
Before driving on extreme uphill and down-
hill gradients, select the LOW RANGE off-
road gear ( Y
page 259).R
Drive slowly. R
Avoid high engine speeds. Drive at appro-
priate engine speeds (maximum
3,000 rpm). R
Use the left-hand steering wheel paddle
shifter to shift into a lower gear in good time
on long and steep downhill gradients. R
Check the brakes after prolonged off-road
driving.
Hill start assist will aid you when pulling away
on a hill. For further information about hill
start assist, see ( Y
page 168).
Do not switch to transmission position N
when driving off-road. If you try to brake the
vehicle using the service brake, you could
lose control of the vehicle. If the gradient is
too steep for your vehicle, drive back down in
reverse gear.
Always observe the approach/departure
angle values ( Y
page 456).
Maximum gradient-climbing capability
Always observe the maximum gradient climb-
ing ability values ( Y
page 456).
Hilltops
When driving up an uphill gradient, slightly
reduce pressure on the accelerator immedi-
ately 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. Oth-
erwise, the vehicle could slip sideways, tip
and rollover. R
Shift to a lower gear using the left-hand
paddle shifter before tackling steep down-
hill gradients. 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
completely braked and therefore lose their
ability to steer.
Driving systems
Intelligent Drive
Mercedes-Benz Intelligent Drive stands for
innovative driver assistance and safety sys-
tems which enhance comfort and support the
driver in critical situations. With these intelli-
gent co-ordinated systems Mercedes-Benz
has set a milestone 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
vehicle occupants and that of other road

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 must202
Driving systems
Driving and parking

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
Driving and parking Z

Tachometer
! Do not drive in the overrevving range, as
this could damage the engine.
The red band in the tachometer indicates the
engine's overrevving range.
The fuel supply is interrupted to protect the
engine when the red band is reached.
Outside temperature display You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.
Bear in mind that the outside temperature
display indicates the temperature measured
and does not record the road temperature.
The outside temperature display is in the mul-
tifunction display ( Y
page 275).
Changes in the outside temperature are dis-
played after a short delay.
Coolant temperature display
G WARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
! A display message is shown if the coolant
temperature is too high.
If the coolant temperature is over 248 ‡
(120 †), do not continue driving. The
engine will otherwise be damaged.
The coolant temperature gauge is in the
instrument cluster on the right-hand side
( Y
page 35). Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 248 ‡ (120 †).
