WARNING
If children open the perfume vial, they could
drink the perfume or it could come into con-
tact with their eyes. There is a risk of injury. Do not leave children unsupervised in the vehicle.
If the perfume liquid has been drunk, consult
a doctor. If perfume comes into contact with
your eyes or skin, rinse the eyes with clean
water. If you continue to experience difficul-
ties, consult a doctor. H
Environmental note Full perfume vials must not
be disposed of with house-
hold rubbish. They must be
collected separately and
recycled to protect the envi-
ronment.
Dispose of full perfume vials

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.

Shift the transmission to position P
(Y page 197).
The transmission position display in the
multifunction display shows

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.
X Turn the SmartKey to position 3in the igni-
tion (Y page 189) lock and release it as
soon as the engine is running.
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. 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.
X Depress the brake pedal and keep it
depressed.
X Press the Start/Stop button once

The engine starts. Pulling away
General notes G
WARNING
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.
When engaging transmission position Dor 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 (Y page 98).
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 the brake pedal is not
depressed, the DIRECT SELECT lever can still be moved but the parking lock remains
engaged.
i Upshifts 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 (Y page 222).
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. 192

WARNING
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: R you are pulling away on a level road or on a
downhill gradient.
R the transmission is in position N.

except plug-in hybrid)
Introduction This section describes the ECO start/stop
function for all vehicles except PLUG-IN
HYBRID vehicles. Information on the ECO
start/stop function in PLUG-IN HYBRID vehi-
cles (Y page 288).
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 G
WARNING
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
If the engine has been switched off automat-
ically by the ECO start/stop function, the
è ECO symbol is shown in the multifunc-
tion display.
Every time you switch on the engine using the SmartKey or the Start/Stop button, the ECO
start/stop function is activated.
The ECO start/stop function is only available in drive program E(drive program Con AMG
vehicles).
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:
R the indicator lamp in the ECO button is lit
green.
R the outside temperature is within the range
that is suitable for the system.
R the engine is at normal operating temper-
ature.
R the set temperature for the vehicle interior
has been reached.
R the battery is sufficiently charged.
R the system detects that the windshield is
not fogged up when the air-conditioning
system is switched on. Driving

wheel paddle shifter (Y page 201).
The automatic transmission shifts up to the
next gear.
If the maximum engine speed on the cur-
rently engaged gear is reached and you
continue to accelerate, the automatic
transmission automatically shifts up in
order to prevent engine damage.
