The following conditions can affect your percep-
tion of the perfume intensity:
Roperating mode of the climate control system
Rinterior temperature
Rtime of year or day
Rair humidity
Rphysiological condition of occupants, e.g. fati-
gue or hunger
The perfume atomizer can only be operated
when the climate control system is switched on
and is only active when the glove box is closed.
The perfume atomizer is provided with a pre-fil-
led vial. You can also choose from a variety of
filled perfume vials and an empty vial which you can fill yourself.
If you refill an empty perfume vial, observe the
separate information sheet attached to the vial.
!If you do not use genuine Mercedes-Benz
interior perfumes, observe the manufactur-
ers' safety notices on the perfume packaging.
Do not refill the pre-filled perfume vial when it is
empty. Dispose of the used vial after use.
XTo insert the perfume vial: open the glove
box (Ypage 326).
XSlide the perfume vial into the holder as far as
it will go.
XTo remove the perfume vial: pull out the
perfume vial.
XTo refill the perfume vial: unscrew the lid of
the empty perfume vial to refill it yourself.
XFill the perfume vial with a maximum of
0.5 fl. oz. (15 ml) of the desired liquid per-
fume.
XScrew the lid back on to the vial.
!Only refill the vial when you are outside the
vehicle. Otherwise, liquid perfume could drip
into the interior and contaminate it.
Always refill the empty refillable vial with the
same perfume. Otherwise, you might not ach-
ieve optimum results from the perfume atom-
izer.
154Operating the climate control systems
Climate control
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If the parking brake has not been fully
released when driving, the parking brake can:
Roverheat and cause a fire
Rlose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
!Do not warm up the engine with the vehicle
stationary. Drive off immediately. Avoid high
engine speeds and driving at full throttle until
the engine has reached its operating temper-
ature.
Only shift the automatic transmission to the
desired drive position when the vehicle is sta-
tionary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
!Mercedes-AMG vehicles: at low engine oil
temperatures below 68 ‡ (+20 †), the max-
imum engine speed is restricted in order to
protect the engine. To protect the engine and
maintain smooth engine operation, avoid driv-
ing at full throttle when the engine is cold.

The SmartKey can be turned in the ignition lock
even if it is not the correct SmartKey for the
vehicle. The ignition is not switched on. The
engine cannot be started.
Start/Stop button
General notes
All vehicles are equipped with a removable
Start/Stop button.
The Start/Stop button must be inserted in the
ignition lock and the Smartkey must be in the
vehicle.
When you insert the Start/Stop button into the
ignition lock, the system needs approximately
two seconds recognition time. You can then use
the Start/Stop button.
Pressing the Start/Stop button several times in
succession corresponds to the different key
positions in the ignition lock. This is only the
case if you are not depressing the brake pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
A check which periodically establishes a radio
connection between the vehicle and the Smart-
Key determines whether a valid SmartKey is in
the vehicle. This occurs, for example, when
starting the engine.
162Driving
Driving and parking
To start the vehicle without actively using the
Smartkey:
Rthe Start/Stop button must be inserted in the

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 87).
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 191).
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.

GWARNING
Electrostatic buildup can create sparks and
ignite fuel vapors. There is a risk of fire and
explosion.
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. Any existing electrostatic buildup is
thereby discharged.
Do not get into the vehicle again during the refu-
eling process. Otherwise, electrostatic charge
could build up again.
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the ignition
if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system. Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. Notify a qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.
!Overfilling the fuel tank could damage the
fuel system.
!Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
!Use a filter when refueling from a fuel can.
Otherwise, the fuel lines and/or injection sys-
tem could be blocked by particles from the
fuel can. If you overfill the fuel tank, fuel could spray out
when the fuel pump nozzle is removed.
