ECO start/stop function
Introduction
The ECO start/stop function switches the
engine off automatically if the vehicle is stopped
under certain conditions.
The engine starts automatically when the driver
wants to pull away again. The ECO start/stop
function thereby helps you to reduce the fuel
consumption and emissions of your vehicle.
Important safety notes
GWARNING
If the engine is switched off automatically and
you exit the vehicle, the engine is restarted
automatically. The vehicle may begin moving.
There is a risk of accident and injury.
If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away.
General notes
:ECO start/stop display
The ECO start/stop function is activated when-
ever you start the engine using the SmartKey or the Start/Stop button.
If the engine has been switched off automati-
cally by the ECO start/stop function, the èECO symbol is shown in the multifunction dis-
play.
Mercedes-AMG vehicles: the ECO start/stop
function is only available in drive programs
Comfort andSlippery.
Automatic engine switch-off
If the vehicle is braked to a standstill in Dor N,
the ECO start/stop function switches off the
engine automatically.
The ECO start/stop function is operational
when:
Rthe indicator lamp in the ECO button is lit
green
Rthe Sport Plus orSport drive program is not
selected (Mercedes-AMG vehicles)
Rno Off-road program has been selected
Rthe outside temperature and the atmospheric
air pressure is within the range that is suitable
for the system
Rthe engine is at normal operating temperature
Rthe set temperature for the vehicle interior
has been reached
Rthe battery is sufficiently charged
Rthe system detects that the windshield is not
fogged up when the air-conditioning system is switched on
Rthe hood is closed
Rthe driver's door is closed and the driver's
seat belt is fastened
All of the vehicle's systems remain active when
the engine is stopped automatically.
The HOLD function can also be activated if the
engine has been switched off automatically. It is
then not necessary to continue applying the
brakes during the automatic stop phase. When
you depress the accelerator pedal, the engine
starts automatically and the braking effect of
the HOLD function is deactivated.
All vehicles (except Mercedes-AMG vehi-
cles): automatic engine switch-off can take
place a maximum of four times in a row (initial
stop, then three subsequent stops).
Mercedes-AMG vehicles: the number of con-
secutive automatic engine switch-offs is unlimi-

Shifting gears
!Mercedes-AMG vehicles: the automatic
transmission does not shift up automatically
even when the engine limiting speed for the
current gear is reached. When the engine lim-
iting speed is reached, the fuel supply is cut to
prevent the engine from overrevving. Always
make sure that the engine speed does not
reach the red area of the tachometer. There is
otherwise a risk of engine damage.
XTo shift up: pull steering wheel paddle
shifter ;.
The automatic transmission shifts up to the
next gear.
All vehicles (except Mercedes-AMG vehi-
cles): if the maximum engine speed in the
gear currently engaged is reached and you
continue to accelerate, the automatic trans-
mission automatically shifts up to prevent
engine damage.
XTo shift down: pull steering wheel paddle
shifter :.
The automatic transmission shifts down to
the next gear.
Automatic down shifting occurs when coast-
ing.
If the engine were to exceed the maximum
engine speed when shifting down, the auto-
matic transmission protects against engine
damage by not shifting down.
Shift recommendation
The gearshift recommendations assist you in
adopting an economical driving style. The rec-
ommended gear is shown in the multifunction
display.
XWhen the corresponding gearshift recom-
mendation :appears in the multifunction
display of the instrument cluster, shift to rec-
ommended gear ;.

Off-road fording
!Under no circumstances should you accel-
erate before entering the water. The bow
wave could cause water to enter and damage
the engine and other assemblies.
!Do not open any of the vehicle's doors while
fording. Otherwise, water could get into the
vehicle interior and damage the vehicle's
electronics and interior equipment.
REstablish how deep the water is and the char-
acteristics of the body of water before ford-
ing.
RSelect the highest possible vehicle level.
RShift to a lower gear using the left-hand steer-
ing wheel paddle shifter.
RAvoid high engine speeds.
REnter and exit the water at a flat place and at
a steady walking pace.
RDrive slowly and at an even speed through the
water.
REnsure that a bow wave does not form as you
drive.
RDo not stop and do not switch off the engine.
Water offers a high degree of resistance, and
the ground is slippery and in some cases
unstable. Therefore, it is difficult and danger-
ous to pull away in the water.
RClean any mud from the tire tread after ford-
ing.
RApply the brakes to dry them after fording.
Always observe the fording depth values
(
Ypage 393).
Winter driving
GWARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
GDANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a
window on the side of the vehicle that is not
facing into the wind.
!When scraping ice off the rear window, take
care not to damage the rear-window seal or
trim.
Have your vehicle winter-proofed at a qualified
specialist workshop at the onset of winter.
Drive particularly carefully on slippery road sur-
faces. Avoid sudden acceleration, steering and
braking maneuvers. Do not use cruise control or
Distance Pilot DISTRONIC.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift the transmission to position i.
XTry to bring the vehicle under control using
corrective steering.
When driving in snow with or without snow
chains, select driving program Slippery
(
Ypage 147).
iVehicles with a diesel engine: do not
cover the radiator, e.g. with a protective
cover. The measuring function of the on-
board diagnosis system may otherwise pro-
vide inaccurate values. Some of these values
are required by law and must therefore always be accurate.
The outside temperature indicator is not
designed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in
wooded areas or on bridges. You should pay
special attention to road conditions when tem-
peratures are around the freezing point.
For more information on driving with snow
chains, see (
Ypage 356).
