Problems with the steering wheel heating
Problem
Possible causes/consequences and
0050
0050Solutions The steering wheel heat-
ing has switched off pre-
maturely or cannot be
switched on. The on-board voltage is too low because too many electrical consum-
ers are switched on.
X Switch off electrical consumers that you do not need, such as the
rear window defroster or interior lighting. EASY-ENTRY/EXIT feature
Important safety notes G
WARNING
When the EASY-ENTRY/EXIT feature adjusts
the steering wheel, you and other vehicle
occupants – particularly children – could
become trapped. There is a risk of injury.
While the EASY-ENTRY/EXIT feature is mak-
ing adjustments, make sure that no one has
any body parts in the sweep of the steering
wheel.
Move the steering wheel adjustment lever if
there is a risk of entrapment by the steering
wheel. The adjustment process is stopped.
Press one of the memory function position but-
tons. This function is only available on vehicles
with memory function. G
WARNING
If children activate the EASY-ENTRY/EXIT fea- ture, they can become trapped, particularly
when unattended. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never leave children unsupervised in the vehicle. G
WARNING
If you drive off while the EASY-ENTRY/EXIT
feature is making adjustments, you could lose
control of the vehicle. There is a risk of an
accident.
Always wait until the adjustment process is
complete before driving off.
The EASY-ENTRY/EXIT feature makes getting in
and out of your vehicle easier. You can activate and deactivate the EASY-
ENTRY/EXIT feature in the on-board computer
(Y page 219).
Position of the steering wheel when the EASY-ENTRY/EXIT feature is active The steering wheel swings up when you:
R remove the SmartKey from the ignition lock.
R open the driver's door and KEYLESS-GO is in
position 0047.
R open the driver's door and the SmartKey is in
position 0092or0047 in the ignition lock.
i The steering wheel only moves up if it has
not already reached the upper stop.
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
R you insert the SmartKey into the ignition lock
or
R you press the Start/Stop button once on vehi-
cles with KEYLESS-GO
When you close the driver's door with the igni-
tion switched on, the steering wheel is also
automatically moved to the previously set posi- tion.
The last position of the steering column is stored
when you:
R switch the ignition off
R save the setting with the memory function
(Y page 105).
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. Steering wheel
101Seats, steering wheel and mirrors Z
This occurs irrespective of the position of the
SmartKey in the ignition lock. This makes it eas-
ier 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 on-board computer
(Y page 219). Mirrors

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. X
Turn the SmartKey to position 0047or0048 in the
ignition lock (Y page 127).
X Exterior mirror on the driver's side: press but-
ton 0043.
Exterior mirror on the front-passenger side:
press button 0044.
The indicator lamp in the corresponding but-
ton lights up in red.
The indicator lamp goes out again after some
time. You can adjust the selected exterior
mirror using button 0087as long as the indicator
lamp is lit.
X Press button 0087up, down, or to the right or
left until you have adjusted the exterior mirror
to the correct position. You should have a
good overview of traffic conditions.
The convex exterior mirrors provide a larger field of vision.
The exterior mirrors are heated automatically if
the rear window defroster is switched on and the
outside temperature is low. 102

Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog up.
To prevent the windows from fogging up:
R Switch off climate control only briefly
R Switch on air-recirculation mode only briefly
R Switch on the cooling with air dehumidifica-
tion function
R Activate the "Windshield defrosting" function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
The residual heat function can only be activated or deactivated with the ignition switched off
(Y page 123).
i Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (Y page 87). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly. If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated (Y page 129).
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants and odors. A clogged filter reduces the
amount of air supplied to the vehicle interior.
Depending on the operating conditions and
environmental influences, the interval for
replacing the filter may be shorter than speci-
fied.
i Vehicles with ionization of the interior
air with air filter: in addition to ionization,
the vehicle has an air filter with anti-allergenic properties that contribute to improved air fil-
tration.
i It is possible that under certain circumstan-
ces the residual heat function may be activa-
ted automatically an hour after the SmartKey has been removed in order to dry the auto-
matic climate control. The vehicle is then ven-tilated for 30 minutes. Control panel for dual-zone automatic climate control

control
The following contains notes and recommenda-
tions on optimum use of the dual-zone auto-
matic climate control or 3-zone automatic cli-
mate control.
R You can switch on climate control by using the
0058 and005A or0058 and0056 buttons.
The indicator lamps in the 0058and
005A buttons or the 0058and0056 buttons
light up.
R Vehicles with 3-zone automatic climate
control: in automatic mode, you can also use
the 00F0 button to set a climate mode
(FOCUS/MEDIUM/DIFFUSE). The MEDIUM
level is recommended.
R Set the temperature to 72 ‡ (22 †).
R Only use the "Windshield defrosting" function
briefly until the windshield is clear again.
R Only use air-recirculation mode briefly, e.g. if
there are unpleasant outside odors or when in a tunnel. The windows could otherwise fog up,
since no fresh air is drawn into the vehicle in
air-recirculation mode.
R Vehicles with 3-zone automatic climate
control: use the ZONE function to adopt the
temperature settings on the driver's side for
the front-passenger side and the rear com-
partment as well. The indicator lamp above
the 00D6 button goes out.
R Vehicles with 3-zone automatic climate
control: use the "residual heat" function if
you want to heat or ventilate the vehicle inte- rior when the ignition is switched off. The
residual heat function can only be activated or
deactivated with the ignition switched off.
R If you change the settings of the climate con-
trol system, the climate status display
appears for approximately three seconds at
the bottom of the screen in the multimedia
system display. You will see the current set-
tings of the various climate control functions.
During automatic engine switch-off, the climate
control system only operates at a reduced capa-
city. If you require the full climate control output, you can switch off the ECO start/stop function
by pressing the ECO button (Y page 132). Operating the climate control sys-

General notes The rear window defroster has a high current
draw. You should therefore switch it off as soon
as the rear window is clear. Otherwise, the rear
window defroster switches off automatically
after several minutes.
If the battery voltage is too low, the rear window defroster may switch off. 122
