Problems with the perfume atomizer
Problem
Possible causes/consequences and
M
MSolutions The vehicle interior is
not perfumed although
the perfume atomizer is
activated. The perfume vial has not been pushed into the holder as far as it
will go.
X Slide the perfume vial into the holder as far as it will go. The perfume vial is not adequately filled.
X Pre-filled vials: dispose of the empty vial.
X Use a new pre-filled vial.
X Refillable vials: refill the vial with a maximum of 15 ml of the
same perfume. The perfume atomizer is faulty.
X Have the perfume atomizer checked at a qualified specialist
workshop. Ionisation
You can use the ionisation function to purify
the air in the vehicle interior and attain an
improved interior climate.
The ionisation of the interior air is odourless
and cannot, directly, be perceived in the vehi-
cle interior.
You can switch ionisation on and off using
COMAND Online (see the separate operating instructions).
Ionisation can only be switched on if the front
automatic climate control is activated. The
side air vent on the driver's side must be
open. Auxiliary heating
Important safety notes G
DANGER
If the exhaust pipe is blocked or sufficient
ventilation is not possible, toxic exhaust
fumes can enter the vehicle, especially car-
bon monoxide. This is the case, e.g. in
enclosed spaces, or if the vehicle is stuck in
snow. There is a risk of fatal injuries. You should switch off the auxiliary heating in
enclosed spaces which do not have an extrac-
tion system, e.g. a garage. If the vehicle is
stuck in snow and you must leave the auxiliary
heating running, keep the exhaust pipe and
the area around the vehicle clear of snow. To guarantee a sufficient supply of fresh air, open
a window on the side of the vehicle away from the wind. G
WARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot.
Flammable materials such as leaves, grass or twigs may ignite if they come into contact
with:
R hot parts of the exhaust system
R the exhaust gas itself
There is a risk of fire. 148

WARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals. G
WARNING
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. G
WARNING
If the parking brake has not been fully
released when driving, the parking brake can:
R overheat and cause a fire
R lose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only set the automatic transmission to the
respective drive positions when the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. Otherwise, you could damage the
drive train.
! AMG vehicles:
at low engine oil temper-
atures (below +20 †), the maximum
engine speed is restricted in order to pro-
tect the engine. To protect the engine and
maintain smooth engine operation, avoid driving at full throttle when the engine is
cold. Key positions

3 To start the engine
If the key does not belong to the vehicle, it can still be turned in the ignition lock. However,
the ignition will not be 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 key must be in the vehi-
cle.
When you insert the Start/Stop button into
the ignition lock, the system needs approx-
imately 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. Driving
159Driving and parking Z

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 key
determines whether a valid key is in the vehi- cle. This occurs, for example, when starting
the engine.
To start the vehicle without actively using the
key:
R the Start/Stop button must be inserted in
the ignition lock
R the key must be in the vehicle
R the vehicle must not be locked with the key
or KEYLESS-GO (Y page 85)
Do not keep the key:
R with electronic devices, e.g. a mobile
phone or another key
R with metallic objects, e.g. coins or metal
film
R inside metallic objects, e.g. a metal case
This can affect the key's functionality.
If you lock the vehicle with the key's remote
control or with KEYLESS-GO, after a short
time:
R you will not be able to switch on the ignition
with the Start/Stop button
R you will not be able to start the engine with
the Start/Stop button until the vehicle is
unlocked again
If you lock the vehicle centrally using the but- ton on the front door (Y page 91), you can
continue to start the engine with the Start/
Stop button.
The engine can be switched off while the vehi-
cle is in motion by pressing and holding the
Start/Stop button for three seconds. This
function operates independently of the ECO
start/stop automatic engine switch-off func-
tion. Key positions with the Start/Stop button

DrivingDriving and parking

Starting procedure with the Start/Stop
button The Start/Stop button can be used to start
the vehicle manually without inserting the key
into the ignition lock. The key must be in the
vehicle and the Start/Stop button must be
inserted in the ignition lock. This mode for
starting the engine operates independently of the ECO start/stop automatic engine start
function.
You can start the engine if a valid key is in the vehicle. Always take the key 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
(Y page 159).
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 92).
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 180).
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 depress it before the vehicle begins to
roll. G
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 a
downhill gradient
R the transmission is in position N
R the electric parking brake is applied
R ESP ®
is malfunctioning ECO start/stop function
Introduction The ECO start/stop function switches the
engine off automatically if the vehicle is stop-

Driving tips
Changing gear The automatic transmission shifts to the indi-
vidual gears automatically when it is in trans-
mission position D. Gearshifting is deter-
mined by:
R the selected drive program (Y page 171)
R the position of the accelerator pedal
(Y page 170)
R the road speed
Accelerator pedal position Your style of driving influences how the auto-
matic transmission shifts gear:
R little throttle: early upshifts
R more throttle: late upshifts 170

missionDriving and parking

transmission immediately shifts into the next
gear up or down, if permitted.
X To shift up: pull the right-hand steering
wheel gearshift paddle (Y page 172).
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.
AMG vehicles: the automatic transmission
will not shift up to the next gear when the
engine speed is very low.
X To shift down: pull on the left-hand steer-
ing wheel gearshift paddle (Y page 172).
The automatic transmission shifts down to the next gear.
If the engine exceeds the maximum engine
speed when shifting down, the automatic
transmission protects against engine dam- age by not shifting down.
Automatic downshifting occurs when
coasting.
