When the engine is running and the vehicle is
stationary: if you move the selector lever from a
driving position toP, the daytime running lamps
and low-beam headlamps go out after three
minutes.
When the engine is running, the vehicle is sta-
tionary and in bright ambient light: if you turn the
light switch to the Tposition, the daytime
running lamps and parking lamps switch on.
If the engine is running and you turn the light
switch to the Lposition, the manual settings
take precedence over the daytime running
lamps.
Low-beam headlamps
GWARNING
When the light switch is set to Ã, the low-
beam headlamps may not be switched on
automatically if there is fog, snow or other
causes of poor visibility due to the weather
conditions such as spray. There is a risk of an
accident.
In such situations, turn the light switch to
L.
Even if the light sensor does not detect that it is
dark, the parking lamps and low-beam head-
lamps switch on when the ignition is switched on and the light switch is set to the Lposition.
This is a particularly useful function in the event
of rain and fog.
XTo switch on the low-beam headlamps:
turn the SmartKey in the ignition lock to posi- tion 2or start the engine.
XTurn the light switch to the Lposition.
The green Lindicator lamp in the instru-

lamps over a period of several hours. If pos-
sible, switch on the right-hand Xor left-
hand W standing lamps.
XTo switch on the parking lamps: turn the

automatically deactivated after some time
except for when the SmartKey is in position 2in
the ignition lock.
The color, brightness, zone and display light for
the ambient lighting are set using the multime-

The front and rear light clusters of your vehicle
are equipped with LED light bulbs. Do not
replace the LED light sources of your vehicle
yourself. Contact a qualified specialist work-
shop which has the necessary specialist knowl-
edge and tools to carry out the work required.
Lamps are an important aspect of vehicle safety.
You must therefore make sure that these func-
tion correctly at all times. Have the headlamp
setting checked regularly.

Switching the residual heat on or off
General notes
Vehicles with rear-compartment climate
control: once the engine is switched off, it is
possible to make use of the residual heat of the
engine to continue heating or ventilating the
rear and front compartment of the vehicle for
approximately 15 minutes. If the "Residual heat"
function is set for only the front or only the rear compartment, it is possible to continue heating
or ventilating for approximately 30 minutes.
Vehicles without rear-compartment climate
control: once the engine is switched off, it is
possible to make use of the residual heat of the
engine to continue heating or ventilating the
front compartment of the vehicle for approx-
imately 30 minutes.
The heating or ventilation time depends on the
temperature that has been set.

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.
HEnvironmental note
Full vials must not be dis-

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.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
Depress the accelerator carefully when pulling
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 84). 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 con-
verter to reach its operating temperature
more quickly.
Information on the automatic release of the
electric parking brake (
Ypage 164).
Hill start assist
Hill start assist helps you when pulling away for-
wards 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 i.
Rthe electric parking brake is applied.

ECO start/stop function
Introduction
Hybrid vehicles: observe the notes on the ECO
start/stop function in the separate operating
instructions.
The ECO start/stop function switches the
engine off automatically if the vehicle is stopped
under certain conditions.
148Driving
Dr iving an d parking
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 switch on the engine using the Smart-
Key or the Start/Stop button.
If the engine has been switched off automati-
cally by the ECO start/stop function, the è
ECO symbol is shown in the multifunction dis-
play.
The ECO start/stop function is only available in drive program E(drive program Con Mercedes-
AMG vehicles).
Automatic engine switch-off
If the vehicle is braked to a standstill with the
transmission in hori, 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 outside temperature is within the range
that is suitable for the system.
Rthe engine is at normal operating tempera-
ture.
Rthe set temperature for the vehicle interior
has been reached.
Rthe battery is sufficiently charged.
Rthe system does not detect any moisture on
the windshield when the automatic climate
control 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 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.
Mercedes-AMG vehicles: the number of con-
secutive automatic engine switch-offs is unlimi-
ted.
All other models: automatic engine switch-off
can take place a maximum of four times in a row
(initial switch-off, then three subsequent switch-
offs).
