service MERCEDES-BENZ GL 2013 Owner's Manual

R
When driving down an incline, make use of
the engine's braking effect. Observe the
engine speed; do not overrev the engine.
R Check the brakes after prolonged off-road
driving.
i Hill start assist will aid you when pulling
away on a hill.
For more information, see "Hill start assist"
(Y page 166).
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.
Maximum gradient-climbing capability On good road surfaces the maximum
gradient-climbing capability of your vehicle is
100%, which corresponds to an approach/
departure angle of 45°. Note that the
vehicle's gradient-climbing capability
depends on the off-road conditions.
Accelerate carefully and make sure that the
wheels do not spin when driving on steep
terrain.
i If the load on the front axle is reduced
when pulling away on a steep uphill slope,
the fron twheels have a tendency to spin.
4ETS recognizes this and brakes the
wheels accordingly. The rear wheel torque
is increased, making it easier to drive off.
Hilltops When driving up an uphill gradient, slightly
reduce pressure on the accelerator
immediately before reaching the brow of the
hill. Use the vehicle's own impetus to drive
over the top of the hill.
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 Before tackling steep downhill gradients,
select shift range 1.
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
Cruise control
Important safety notes If you fail to adapt your driving style, cruise
control 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
accelerating could cause the drive wheels Driving systems
195Driving and parking Z

DISTRONIC PLU
Suses additional information
from your navigation system so that it can
react appropriately to certain traffic
situations. This is the case if, while following
a vehicle, DISTRONIC PLUS is active and you:
R approach or drive through a traffic circle
R approach a T-intersection
R turn off at a highway exit
Even if the vehicle in front leaves the
detection range, DISTRONIC PLUS
temporarily maintains the current driving
speed and does not accelerate. This is based
on the current map data in the navigation
system.
The current speed is maintained:
R approximately 10 seconds before the
traffic circle/T intersection and
approximately 1.5 seconds when driving on
a traffic circle.
R approximately 12 seconds before reaching
a highway exit and approximately
4s econds after the highway exit.
Afterwards, the vehicle accelerates back to
the set speed you specified.
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
vehicle occupan torfrom outside the
vehicle.
R the electrical system in the engine
compartment, 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 yourv ehicle 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
distance, your vehicle will come to a standstill
at a sufficien tdistance 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
automatically switched off by the ECO
start/stop function.
R a system malfunction occurs.
R the power supply is not sufficient.
On steep uphill or downhill inclines or if there
is a malfunction, the transmission may also
automatically be shifted into position P.

General notes AIRMATIC regulates the level of your vehicle.
As well as level control (Y
page 213), your
vehicle can be equipped with ADS (Adaptive
Damping System) (Y page 212) and ACTIVE
CURVE SYSTEM (Y page 213).
Observe the notes on driving with a trailer
(Y page 257).
ADS (Adaptive Damping System) General notes
ADS adapts the damping characteristics to
the current operating and driving situation.
This depends on:
R
your driving style
R the road surface conditions
R the ADS setting
R the vehicle level setting
Your selection remains stored even if you
remove the SmartKey from the ignition lock.
