2016 MERCEDES-BENZ C CLASS wheel

Position of the steering wheel for driv-
ing The steering wheel is moved to the last selected
position when: R
the driver's door is closed and you insert the
SmartKey into the ignition lock R
you close the driver's door when the ignition
is switched on R
you press the Start/Stop button once on vehi-
cles with KEYLESS-GO
i The steering wheel only returns to the last
set position if the driving position is stored
after the seat or steering column has been
adjusted ( Y
page 116).
The most recent driving position of the steering
wheel is stored if: R
the ignition is switched off R
the setting is stored with the memory function
( Y
page 116).
Crash-responsive EASY-EXIT feature If the crash-responsive EASY-EXIT feature is trig-
gered in an accident, the steering column will
move upwards when the driver's door is opened
or the SmartKey is removed from the ignition
lock. This makes it easier to exit the vehicle and
rescue the occupants.
The crash-responsive EASY-EXIT feature is only
operational if the EASY-EXIT/ENTRY feature is
activated in the multimedia system (see the sep-
arate operating instructions).

G WARNING
You could lose control of your vehicle if you do
the following while driving: R
adjust the driver's seat, head restraint,
steering wheel or mirrors R
fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt
before starting the engine.
G WARNING
The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.
This means that you could misjudge the dis-
tance from road users traveling behind, e.g.
when changing lane. There is a risk of an acci-
dent.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder.

Pre-entry climate control at time of
departure
Important safety notes
G WARNING
If persons, particularly children are subjected
to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
General notes The "Pre-entry climate control at departure
time" function is only available in PLUG-IN
HYBRID vehicles.
You can use the "Pre-entry climate control at
departure time" function to cool or heat the
vehicle interior if the engine is not running.
The "Pre-entry climate control at departure
time" function can be activated regardless of
whether or not the vehicle is connected to an
electric power supply. The condition of charge of
the high-voltage battery must be higher than the
specified minimum condition of charge, how-
ever.
When the vehicle is connected to an electric
power supply, priority is given to charging the
high-voltage battery to the specified minimum charge. "Pre-entry climate control at departure
time" is only activated subsequently.
The running time of the "Pre-entry climate con-
trol at departure time" function may be reduced
if: R
the vehicle is not connected to an electric
power supply and R
the high-voltage battery is not fully charged
With active "Pre-entry climate control at depar-
ture time" the condition of charge of the high-
voltage battery can be reduced, even if the
charge cable connector is connected.
When the vehicle is cooled, the following func-
tions are activated if required: R
Climate control system R
Blower R
Seat ventilation
When the vehicle is heated, the following func-
tions are activated if required: R
Climate control system R
Blower R

Setting the departure time You can set the departure time using the on-
board computer or via the online access to the
vehicle. The activation of the "Pre-entry climate
control at departure time" function can be linked
to this departure time. Your vehicle will then be
cooled or heated until the desired temperature
is reached in time for the set departure time.
"Pre-entry climate control at departure time" will
be activated a maximum of 55 minutes before
departure. If the departure is delayed, the vehi-
cle will be heated or cooled for another five
minutes. X
To set the departure time: set the departure
time using the on-board computer
( Y
page 249). Set the departure time via the
online access to the vehicle ( Y
page 176).X
To activate or deactivate "Pre-entry cli-
mate control at departure time": activate
or deactivate "Pre-entry climate control at
departure time" via the multimedia system
( Y
page 303). Set the "Pre-entry climate con-
trol at departure time" via the online access to
the vehicle ( Y
page 176).
When activating the "Pre-entry climate control
at departure time" function: you can select
whether only the driver's area or also the front-
passenger area should be heated or cooled.
The "Pre-entry climate control at departure
time" function switches off automatically when
the
vehicle is started. The following functions
remain active: R
Seat heating R
Seat ventilation R
Steering wheel heating R
Perfume atomizer R

Switching off "Pre-entry climate control at
departure time": the activated "Pre-entry cli-
mate control at departure time" can be switched
off using the rocker switch ( Y
page 143).
Activating or deactivating "Immediate
pre-entry climate control" using the
rocker switch
You can activate "Immediate pre-entry climate
control" even if the vehicle interior is already at the desired temperature. This means, for exam-
ple, that the vehicle interior continues to be
cooled or heated if the journey is interrupted for
up to 50 minutes and the interior temperature is
kept constant.
X
To activate or deactivate "Immediate pre-
entry climate control": press rocker
switch C up or down.
The blue or red indicator lamp above the
rocker switch lights up or goes out.
The colors of the indicator lamps in rocker
switch C have the following meanings: R
blue: cooling activated R
red: heating activated R
yellow: departure time is preselected
Air vents
Important safety notes
G WARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes: R
keep the air inlet between the windshield and
the hood free of blockages, such as ice, snow
or leaves. R
never cover the air vents or air intake grilles in
the vehicle interior. Air vents 143

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.
! 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.

Vehicles with AIRPANEL: you can open the
shutters in the radiator trim by turning the
SmartKey to position 2 in the ignition lock. After
approximately 120 seconds the shutters open
automatically. Further information on opening
and cleaning the shutters ( Y
page 339).
Start/Stop button
General notes
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.146
