Problems with the steering wheel heating
ProblemPossible causes/consequences andMSolutions
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.
XSwitch off electrical consumers that you do not need, such as the
rear window defroster 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
GWARNING
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 one of the memory function posi-
tion buttons. The adjustment process is stop-
ped.
GWARNING
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.
GWARNING
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
(
Ypage 208).
Position of the steering wheel when the
EASY-ENTRY/EXIT feature is active
The steering wheel swings upwards when you:
Rremove the SmartKey from the ignition lock
Rwith KEYLESS-GO: open the driver's door;
KEYLESS-GO must be in position 1
Rwith the SmartKey:open the driver's door;
the SmartKey is in position 0or 1must be in
the ignition lock (
Ypage 127).
iThe steering wheel only moves upwards if it
has not already reached the upper stop.

ing
The steering wheel is moved to the last selected position when:
Rthe driver's door is closed
Rwith KEYLESS-GO: you press the Start/Stop
button once
or
Rwith the SmartKey: you insert the SmartKey
into the ignition lock

Seats, steering wheel and mirrors
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
(
Ypage 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. 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
(
Ypage 208).
Mirrors
Exterior mirrors
Adjusting the exterior mirrors
GWARNING
You could lose control of your vehicle if you do the following while driving:
Radjust the driver's seat, head restraint,
steering wheel or mirrors
Rfasten 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.
GWARNING
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.

tions.
The convex exterior mirrors provide a larger field
of vision.
After the engine has been started, the exterior
mirrors are automatically heated if the rear win-
dow defroster is switched on and the outside
temperature is low. Heating takes a maximum of
ten minutes.
iYou can also heat up the exterior mirrors
manually by switching on the rear window
defroster.

Rear view camera
General notes
Rear view camera :is an optical parking and
maneuvering aid. It shows the area behind your
vehicle with guide lines in the multimedia sys-
tem display.
The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
iThe text shown in the multimedia system
display depends on the language setting. The
following are examples of rear view camera
messages in the multimedia system display.
Important safety notes
The rear view camera is only an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering and parking. When maneu-
vering or parking, make sure that there are no
persons, animals or objects in the area in which you are maneuvering.
Under the following circumstances, the rear
view camera will not function, or will function in
a limited manner:
Rif the trunk lid is open
Rin heavy rain, snow or fog
Rat night or in very dark places
Rif the camera is exposed to very bright light
Rif the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)
Rif there is a sudden change in temperature,
e.g. when driving into a heated garage in win- ter
Driving system s177
Driving an d parking
Z
Rif the camera lens is dirty or obstructed
Observe the notes on cleaning
(
Ypage 282)
Rif the rear of your vehicle is damaged. In this
event, have the camera position and setting
checked at a qualified specialist workshop
The field of vision and other functions of the rear
view camera may be restricted due to additional
accessories on the rear of the vehicle (e.g.
license plate holder, bicycle rack).
On vehicles with height-adjustable chassis,
leaving the standard height can result in inac-
curacies in the guide lines, depending on tech-
nical conditions.
iThe rear view camera is protected from rain-
drops and dust by means of a flap. When the
rear view camera is activated, this flap opens.
The flap closes again when:
Ryou have finished the maneuvering process
Ryou switch off the engine
Ryou open the trunk
Observe the notes on cleaning (
Ypage 282).
For technical reasons, the flap may remain
open briefly after the rear view camera has
been deactivated.
Activating/deactivating the rear view
camera
XTo activate: make sure that the SmartKey is
in position 2in the ignition lock.
XMake sure that the Activation by R gearfunction is selected in the multimedia system
(see the Digital Operator's Manual).
XEngage reverse gear.
The rear view camera flap opens. The area
behind the vehicle is shown with guide lines in
the multimedia system display.
The image from the rear view camera is avail-
able throughout the maneuvering process.
To deactivate: the rear view camera deacti-
vates if you shift the transmission to Por after
driving forwards a short distance.
Messages in the multimedia system dis- play
The rear view camera may show a distorted view
of obstacles, show them incorrectly or not at all.
The rear view camera does not show objects in
the following positions:
Rvery close to the rear bumper
Runder the rear bumper
Rin the area immediately above the tailgate
handle
!Objects not at ground level may appear to
be further away than they actually are, e.g.:
Rthe bumper of a parked vehicle
Rthe drawbar of a trailer
Rthe ball coupling of a trailer tow hitch
Rthe rear section of an HGV
Ra slanted post
Use the guidelines only for orientation.
Approach objects no further than the bottom-
most guideline.
