Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
GWARNING
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on the seat guide rail. There is a risk of injury.
Make sure when adjusting a seat that no one
has any body parts in the sweep of the seat.
Observe the safety notes on "Air bags"
(
Ypage 50) and "Children in the vehicle"
(
Ypage 62).
Folding the seat backrest forward
The seat moves forwards as soon as you fold
the backrest forwards.
This makes it easier for passengers to get into
and out of the rear compartment. The head
restraint is lowered in the process and the
seat moves forwards.
XPull seat release handle :forwards and
fold the backrest forwards as far as it will
go.
The seat automatically moves to the fore-
most position and the head restraint is low-
ered.
Folding the seat backrest back
XFold back the backrest horizontally until it
engages.
If the rear seat backrest is not engaged, this
will be shown in the multifunction display in
the instrument cluster. A warning tone also
sounds.
The seat moves automatically to the last
position.
Adjusting the active multicontour
seat
The settings for the active multicontour seat
are only activated if:
Rthe seat is occupied
Rthe seat belt is fastened.
Vehicles installed with the Seat Comfort
package: you can adjust the active multicon-
tour seat for the driver and front passenger
with COMAND (see the separate operating
instructions).
Adjusting the 4-way lumbar support
The 4-way lumbar support can be adjusted
with COMAND (see the separate operating
instructions).
Switching the seat heating on/off
Switching on/off
GWARNING
Repeatedly switching on the seat heating can
cause the seat cushion and backrest pads to
become very hot. The health of persons with
limited temperature sensitivity or a limited
ability to react to excessively high tempera-
tures may be affected or they may even suffer
burn-like injuries. There is a risk of injury.
Therefore, do not switch the seat heating on
repeatedly.

Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake.
Rshifting the automatic transmission out of
park position P
RStart the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
GWARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or
parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.
!Do not depress the accelerator when
starting the engine.
General notes
During a cold start, the engine runs at higher
speeds to enable the catalytic converter to
reach its operating temperature. The sound of
the engine may change during this time.
Automatic transmission
XShift the transmission to position P
(
Ypage 159).
The transmission position display in the
multifunction display shows
P (
Ypage 161).
You can start the engine in transmission posi-
tion Pand N.
Starting procedure with the SmartKey
To start the engine using the SmartKey
instead of the Start/Stop button, pull the
Start/Stop button out of the ignition lock.
XTurn the SmartKey to position 3in the igni-
tion lock and release it as soon as the
engine is running (
Ypage 151).

Z

When engaging transmission positionDor R,
always firmly depress the brake pedal and do
not simultaneously accelerate.
Depress the accelerator carefully when pull-
ing away.
The vehicle locks centrally once you have
pulled away. The locking knobs in the doors
drop down.
You can open the doors from the inside at any time.
You can also deactivate the automatic locking
feature (
Ypage 90).
It is only possible to shift the transmission
from position Pto the desired position if you
depress the brake pedal. Only then is the
parking lock released.
If you do not depress the brake pedal, the
DIRECT SELECT lever can still be moved but
the parking lock remains engaged.
iUpshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Information on the automatic release of the
electric parking brake (
Ypage 172).
Hill start assist
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It
holds the vehicle for a short time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and to depress it before the vehicle begins to
roll.
GWARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if:
Ryou are pulling away on a level road or on a downhill gradient.
Rthe transmission is in position N.
Rthe electric parking brake is applied.
RESP®is malfunctioning.
ECO start/stop function
Introduction
The ECO start/stop function switches the
engine off automatically if the vehicle is stop-
ped 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.

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
