Important safety notes
G
WARNING
Children could become trapped if they adjust
the seats, 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
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,
steering wheel and mirror and fasten your
seat belt before starting the engine. G
WARNING
If you adjust the seat height carelessly, you or
other vehicle occupants could be trapped and
thereby injured. Children in particular could
accidentally press the electrical seat adjustment buttons and become trapped.
There is a risk of injury.
While moving the seats, make sure that your
hands or other body parts do not get under
the lever assembly of the seat adjustment
system.
G
WARNING
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on the
seat guide rail. There is a risk of injury.
Make sure when adjusting a seat that no one
has any body parts in the sweep of the seat. G
WARNING
If head restraints are not installed and
adjusted correctly, they cannot provide
protection as intended. There is an increased
risk of injury in the head and neck area, e.g.
in the event of an accident or when braking.
Always drive with the head restraints
installed. Before driving off, make sure for
every vehicle occupant that the center of the
head restraint supports the back of the head
at about eye level. G
WARNING
The seat belt does not offer the intended level
of protection if you have not moved the
backrest to an almost vertical position. When
braking or in the event of an accident, you
could slide underneath the seat belt and
sustain abdomen or neck injuries, for
example. This poses an increased risk of
injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder. Seats

To avoid damage to the seats and the seat
heating, observe the following information:
R keep liquids from spilling on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
R if the seat covers are damp or wet, do not
switch on the seat heating. The seat
heating should also not be used to dry
the seats.
R clean the seat covers as recommended;
see "Interior care".
R do not transport heavy loads on the
seats. Do not place sharp objects on the
seat cushions, e.g. knives, nails or tools.
The seats should only be occupied by
passengers, if possible.
R when the seat heating is in operation, do
not cover the seats with insulating
materials, e.g. blankets, coats, bags,
seat covers, child seats or booster seats.
! Make sure that there are no objects in the
footwell or behind the seats when resetting
the seats. There is a risk that the seats
and/or the objects could be damaged.
i The head restraints in the front seats are
installed with the NECK-PRO system
(Y page 53). For this reason, it is not
possible to remove the head restraints
from the front seats.
Vehicles without the through-loading
feature: the head restraints cannot be
removed from the rear compartment seats.
For more information, contact a qualified
specialist workshop. Adjusting the seats
:
Head restraint height
; Seat cushion angle
= Seat height
? Seat fore-and-aft adjustment
A Backrest angle
i If PRE-SAFE ®
is triggered, the front-
passenger seat will be moved to a better
position if it was previously in an
unfavorable position.
i You can store the seat settings using the
memory function (Y page 125).
i Vehicles with the through-loading
feature: if you fold down a rear seat
backrest, the respective front seat is
moved forwards slightly if necessary. This
prevents the seats from colliding. Adjusting the head restraints

Problems with the steering wheel heating
Problem Possible causes/consequences and
M
MSolutions The steering wheel
heating has switched
off prematurely or
cannot be switched on. The on-board voltage is too low because too many electrical
consumers are switched on.
X
Switch 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 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
making adjustments, make sure that no one
has any body parts in the sweep of the
steering wheel.
If somebody becomes trapped:
R press one of the memory function position
buttons, or
R move the switch for steering wheel
adjustment in the opposite direction to that
in which the steering wheel is moving.
The adjustment process is stopped. G
WARNING
If children activate the EASY-ENTRY/EXIT
feature, 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 252).
Position of the steering wheel when the
EASY-ENTRY/EXIT feature is active The steering wheel swings upwards when
you:
R
remove the SmartKey from the ignition lock
R with KEYLESS-GO: open the driver's door;
KEYLESS-GO must be in position 1
R with the SmartKey: open the driver's
door; the SmartKey must be in position 0
or 1in the ignition lock (Y page 159)
i The steering wheel only moves upwards if
it has not already reached the upper end
stop. Steering wheel
121Seats, steering wheel and mirrors Z
ProCarManuals.com

Position of the steering wheel for
driving The steering wheel is moved to the last
selected position when:
R the driver's door is closed
R with KEYLESS-GO: you press the Start/
Stop button once on vehicles with
KEYLESS-GO
or
R with the SmartKey: you insert the
SmartKey into the ignition lock.
When you close the driver's door with the
ignition switched on, the steering wheel is
also automatically moved to the previously
set position.
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 125).
Crash-responsive EASY-EXIT feature If the crash-responsive EASY-EXIT feature is
triggered 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 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.

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,
steering wheel and mirror and fasten your

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
distance from road users traveling behind,
e.g. when changing lane. There is a risk of an
accident.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder. 122
