Starting procedure with the Start/Stop
button
The Start/Stop button can be used to start
the vehicle manually without inserting the
SmartKey into the ignition lock. The Start/
Stop button must be inserted in the ignition
lock and the SmartKey must be in the vehicle.
This mode for starting the engine operates
independently of the ECO start/stop auto-
matic engine start function.
You can start the engine if a valid SmartKey is
in the vehicle. Switch off the engine and
always take the SmartKey with you when
leaving the vehicle, even if you only leave it for
a short time. Pay attention to the important
safety notes.
XDepress the brake pedal and keep it
depressed.
XPress the Start/Stop button once
(
Ypage 147).
The engine starts.
Starting procedure via smartphone
Observe the important safety notes on start-
ing the engine (
Ypage 149).
You can also start your engine via your smart-
phone from outside the vehicle. In this case,
the previously selected climate control set-
ting is activated. In this way you can cool or
heat the interior of the vehicle before starting
the journey.
Only start the engine via your smartphone if it
is safe to start and run the engine where your
vehicle is parked.
Observe the legal stipulations in the area
where your vehicle is parked. Engine start via
smartphone may be limited to certain coun-
tries or regions.
You can execute a maximum of two consec-
utive starting attempts via your smartphone.
If you insert the key into the ignition lock, you
can carry out two more starting attempts.
Once you have started the engine, you can
switch the engine off via your smartphone at
any time. You can only start the engine via your smart-
phone if:
Rthe key is in the ignition lock
Rpark position Pis selected
Rthe accelerator pedal is not depressed
Rthe anti-theft alarm system is not activated
Rthe panic alarm is not activated
Rthe hazard warning lamps are switched off
Rthe hood is closed.
Rthe doors are closed and locked
Rthe windows and sliding sunroof are closed
Also make sure that:
Rthe fuel tank is sufficiently filled
Rthe starter battery is sufficiently charged
GWARNING
Limbs could be crushed or trapped if the
engine is started unintentionally during ser-
vice or maintenance work. There is a risk of
injury.
Always secure the engine against uninten-
tional starting before carrying out mainte-
nance or repair work.
Make sure that the engine cannot be started
via your smartphone before carrying out
maintenance or repairs. You can prevent an
engine start via your smartphone, for exam-
ple, if you:
Rswitch on the hazard warning lamps
Rdo not lock the doors
Ropen the hood.
Pulling away
General notes
GWARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is
a risk of an accident.
150Driving
Driving and parking

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 222).
It is only possible to shift the transmission
from position Pto the desired position if you
depress the brake pedal. Only then can the
parking lock be deactivated.
All vehicles (except Mercedes-AMG vehi-
cles): if you do not depress the brake pedal,
the DIRECT SELECT lever can still be moved
but the parking lock remains engaged.
Mercedes-AMG vehicles: if you do not
depress the brake pedal, the selector lever
can still be moved but the parking lock
remains engaged.
At transmission fluid temperatures below
Ò4 ‡ (Ò20 †), you can only shift out of park
position Pinto another transmission position
when the engine is running.
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 171).
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.
Further information on holding the vehicle
stationary on uphill gradients (
Ypage 161).
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.
