Problems with the steering wheel heating
Problem
Possible causes/consequences and
M
MSolutions The steering wheel heat-
ing has switched itself
off prematurely or can-
not 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 heating or interior lighting.
Once the battery is sufficiently charged, the steering wheel heating
will switch back on automatically. 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.
Vehicles with a memory function: if there is a
risk of becoming trapped by the steering wheel, you can also press one of the memory function
position buttons. The adjustment process is
stopped. 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 key with you and lock the vehicle. Never leave
children unattended 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 227).
Position of the steering wheel when the EASY-ENTRY/EXIT feature is active The steering wheel tilts upwards if you:
R remove the key from the ignition lock
R with KEYLESS-GO: open the driver's door;
KEYLESS-GO must be in position 1
R with the key: open the driver's door; the key
must be in position 0or 1in the ignition lock
(Y page 139)
i The steering wheel only moves upwards if it
has not already reached the upper stop.
Position of the steering wheel for driv-
ing The steering wheel is moved to the previously
set position if:
R the driver's door is closed and
R with KEYLESS-GO: you press the Start/Stop
button once
or
R with the key: you insert the key into the igni-
tion lock
If you close the driver's door with the key inser-
ted in the ignition lock, the steering wheel is
automatically moved to the previously set posi- tion. Steering wheel

The last position of the steering wheel is stored
when you switch off the ignition or when you
store the setting with the memory function
(Y page 112).
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. This occurs irrespective of the position of the
key in 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 on-board computer
(Y page 227). Mirrors

R Only use the "Windscreen demisting" function
briefly until the windscreen is clear again.
R Only use air-recirculation mode briefly, e.g. if
there are unpleasant outside odours or when
in a tunnel. The windows could otherwise mist
up as no fresh air is drawn into the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the temper-
ature settings on the driver's side for the
front-passenger side and the rear compart-
ment as well. The indicator lamp above the
á button goes out.
R Vehicles with THERMOTRONIC: use the resid-
ual heat function if you want to heat or venti-
late the vehicle interior when the ignition is switched off. The residual heat function can
only be activated or deactivated with the igni-
tion switched off.
