1Event ahead2Distance display for the event ahead3"Foot oM the accelerator" prompt
Displayable route events 1
The segments of distance display 2 show the
distance to the event ahead as follows:
= A few segments light up: the event ahead is
near.
= Many segments light up: the event ahead is
further away.
When the vehicle nears the event, ECO Assist will
calculate the optimal speed for maximum fuel economy and recuperative energy based on the
distance, speed and gradient. The Foot off the
Accelerator message 3 appears in the instru-
ment display. The Nrst segments in front of the
vehicle will turn green. The remaining segments
will initially stay white. If you take your foot oM the
accelerator pedal in good time, the remaining seg-
ments on the display will successively turn green
until the event shown is reached. The drivetrain
will be set for maximum fuel economy. Recupera-
tion will charge the battery. Recuperation will be
adapted to the selected drive program.
The event will be shown for a short time aser it
has been passed. If there is no response to the
Foot off the Accelerator prompt, the segments
will remain white.If the event involves a vehicle in front, all seg- ments will immediately turn green once there is a
response to the Foot off the Accelerator prompt.
For active ECO Assist in drive program ,
symbol 3 will appear on the instrument display
and on the head-up display beside transmission
position [. Symbol 3 will also appear when the
assistant display is not selected.
If the system does not intervene during the event
ahead, nothing will be displayed. The system will be passive.
ECO Assist is active only in drive programs 
and A .
System limits
ECO Assist can function even more precisely if
the route is adhered to when route guidance is active. The basic function is also available without
active route guidance. Not all information and
traPc situations can be foreseen. The quality
depends on the map data.
ECO Assist is only an aid. The driver is responsible
for keeping a safe distance from the vehicle in front, for vehicle speed and for braking in good
time. The driver must be ready to brake at allDriving and parking189

times, irrespective of whether the system inter-venes.
The system may be impaired or may not function in the following situations:
= If visibility is poor, e.g. due to insuPcient illu-
mination of the road, highly variable shade
conditions, rain, snow, fog or heavy spray.
= If there is glare, e.g. from oncoming traPc,
direct sunlight or reOections.
= If there is dirt on the windshield in the area of
the multifunction camera or the camera is fog-
ged up, damaged or obscured.
= If road signs are hard to detect, e.g. due to
dirt, snow or insuPcient lighting, or because
they are obscured.
= If the information on the navigation system\bs
digital map is incorrect or out of date.
= If signs are ambiguous, e.g. road signs in road-
works or in adjacent lanes.DYNAMIC SELECT switch

&WARNING Risk of accident due to incor-
rect gearshising
If the engine speed is higher than the idle
speed and you engage the transmission posi-
tion [ or ^, the vehicle may accelerate
sharply.
If you engage the transmission position
[ or ^ when the vehicle is at a stand-still, always depress the brake pedal
Nrmly and do not accelerate at the same
time.&WARNING Risk of accident and injury due
to children les unattended in the vehicle
If children are les unsupervised in the vehicle,
they could, in particular:
= open doors, thereby endangering other
persons or road users.
= get out and be struck by oncoming traPc.
= operate vehicle equipment and become
trapped, for example.
In addition, the children could also set the
vehicle in motion, for example by:
= releasing the parking brake.
= changing the transmission position.
= starting the vehicle.
Never leave children unattended in the
vehicle.When leaving the vehicle, always take the SmartKey with you and lock the vehicle.Keep the vehicle SmartKey out of reach
of children.

Glide mode function*NOTE Mercedes-AMG vehiclesObserve the notes in the Supplement.
You could otherwise fail to recognize
dangers.\bMercedes-Maybach vehicles: The Glide mode
function is not available.
With an anticipatory driving style, Glide mode
helps you to reduce fuel consumption.
Glide mode is characterised by the following: = The combustion engine is disconnected from
the drivetrain and continues to run in neutral.
= The transmission position display [ is shown
in green.
= Vehicles with 48 V on-board electrical system:
The combustion engine can be switched oM.
All of the vehicle functions remain active.
Glide mode is activated if the following conditions are met:
= Drive program  is selected.
=
The speed is within a suitable range.
= The road\bs course is suitable, e.g. no steep
uphill or downhill inclines or tight bends.
= There is no trailer hitched up to the trailer
hitch, and no bicycle rack installed.
= You do not depress the accelerator or brake
pedal (except for light brake applications).\bGlide mode can also be activated if you have
selected the "Eco" setting for the drive in the drive program .
Glide mode will be deactivated again if one of the
conditions is no longer met.
Glide mode can also be prevented by the following
parameters:
= Incline
= Downhill gradient
= Temperature
= Height
= Speed
= Operating status of the engine
= TraPc situation
Transfer case
Function of the transfer case
&WARNING Risk of skidding and having an
accident when in LOW RANGE on slippery
road surfaces
The wheels can block and thus lose traction
on slippery road surfaces, particularly in the
following situations:
= if you release the accelerator pedal when
the vehicle is in motion.
= if oM-road ABS intervenes when braking.
Never select the LOW RANGE oM-road
gear when driving on slippery road surfa-
ces.&WARNING Risk of accident when the
transfer case is in neutral position
The vehicle may roll away unintentionally if you
do not wait until the transfer case shis opera-
tion is complete.
