Seats
Important safety notes
G
WARNING
The seats can still be adjusted when there is
no key in the ignition lock. For this reason,
children should never be left unsupervised in
the vehicle. They could otherwise become
trapped when adjusting the seat. G
WARNING
Make sure that the back of your head is
supported at eye level by the central area of
the head restraint. If your head is not
supported correctly
by the head restraint, you
could suffer a severe neck injury in the event
of an accident. Never drive if the head
restraints are not engaged and set correctly. G
WARNING
In order to avoid possible loss of vehicle
control, all seat, head restraint, steering
wheel and rear view mirror adjustments, as
well as fastening of seat belts, must be done
before setting the vehicle in motion. G
WARNING
Do not adjust the driver's seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never travel

in a moving vehicle with the seat
backrest in an excessively reclined position as
this can be dangerous. You could slide under
the seat belt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck. This could cause serious or
fatal injuries. The seat backrest and seat belts
provide the best restraint when the wearer is
in a position that is as upright as possible and
seat belts are properly positioned on the
body. G
WARNING
Your seat belt must be adjusted so that you
can correctly fasten your seat belt. Observe the following points:
R
adjust the

seat backrest until your arms are
slightly angled when holding the steering
wheel.
R adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The
position should be as far back as possible
with the driver still able to operate the
controls properly.
R adjust the head restraint so that it is as
close to the head as possible and the center
of the head restraint supports the back of
the head at eye level.
R never place hands under the seat or near
any moving parts while a seat is being
adjusted.
Failure to do so could result in an accident
and/or serious personal injury. G
WARNING
Children 12 years old and under must be
seated and

properly secured in an appropriate
infant restraint, toddler restraint, or booster
seat recommended for the size and weight of
the child. Additional information can be found
under "Children in the vehicle".
A child's risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.
! 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". Seats

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.

G
WARNING
When adjusting the front passenger seat,
make sure

the seat, if occupied, is as far from
the front passenger front air bag as possible.
Otherwise, the passenger could be seriously
or even fatally injured in the event of an
accident or braking maneuver.
Make sure no one is caught or injured while
the seat is being adjusted.
Even with the SmartKey or SmartKey with
KEYLESS-GO removed from the starter switch
or the SmartKey with KEYLESS-GO removed
from the vehicle, the power seats can be
operated. Therefore, do not leave children
unattended in the vehicle, or with access to
an unlocked vehicle. A child's unsupervised
access to a vehicle could result in an accident
and/or serious personal injury.
! Do not move the front-passenger seat
fully forwards if there are objects in the
parcel net in the front-passenger footwell.
The objects could otherwise be damaged. You can use the seat switches on the driver's
side to adjust the front-passenger seat.

Important safety notes
For reasons of safety, Mercedes-Benz
recommends that you drive with the lights
switched on

even during the daytime. In some
countries, operation of the headlamps varies
due to legal requirements and self-imposed
obligations. Driving abroad
Conversion to symmetrical low beam Switch the headlamps to symmetrical low
beam in countries in which traffic drives on
the
opposite

side of the road from the country
where the vehicle is registered. This prevents
glare to oncoming traffic. When using
symmetrical lights, the edge of the road is not
lit as widely and as far ahead as normal.
Have the headlamps converted at a qualified
specialist workshop as close to the border as
possible before driving in these countries.
Conversion to asymmetrical low beam
after returning Have the headlamps converted back to
asymmetrical low-beam headlamps at a
qualified specialist workshop as soon as
possible after crossing the border again. Light switch
Operation !
If the battery has been excessively
discharged, the parking lamps or standing
lamps are automatically switched off to
enable the next engine start. Always park
your vehicle safely and sufficiently lit
according to legal standards. Avoid the

for several

hours. If possible, switch on the
