The electro-hydraulic brake system must be
deactivated prior to working on the system.
High pressure is intermittently built up in the
system as part of its automatic self-test.
In addition, the system is automatically
activated when the vehicle is unlocked by
remote control, when the driver or passenger
door is opened, when the SmartKey in the
starter switch is turned to position 1 or the
KEYLESS-GO start/stop button is pressed
once, when the brake pedal is depressed or
when the parking brake is released. Failure to
deactivate the system prior to maintenance
will cause brake pistons to extend and brake
fluid to leak, which may result in injuries
(contusions and acid burns). Extended brake
pistons may also cause injury.
The electro-hydraulic brake system switches
off automatically
R approximately 2 minutes after you turned
the SmartKey in the starter switch to
position 0 or removed the SmartKey
R approximately 2 minutes after you pressed
the KEYLESS-GO start/stop button to turn
off the engine or power supply and opened
the driver’s door (with driver’s door open,
the starter switch is set to position 0, same
as SmartKey removed from starter switch)
R approximately 20 seconds after you locked
the vehicle from outside
For more information on your vehicle’s
brakes, see the “Driving instructions” section

Seats
Safety notes
GWarning!
In order to avoid possible loss of vehicle
control the following must be done before the
vehicle is put into motion:
R seat adjustment
R head restraint adjustment
R steering wheel adjustment
R rear view mirror adjustment
R fastening of seat belts
GWarning!
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 ride 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. That 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.
GWarning!
Your seat 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. The center of
the head restraint must support 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.GWarning!
The power seats can be operated at any time.
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.
GWarning!
Children 12 years old and under must be
seated and properly secured in an
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child. For additional
information, see section “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.
GWarning!
For your protection, drive only with properly
positioned head restraints.
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. This will reduce the potential for
injury to the head and neck in the event of an
accident or similar situation.
Do not drive the vehicle without the seat head
restraints. Head restraints are intended to
help reduce injuries during an accident.

Shift the automatic transmission
into reverse gear R only when the
vehicle is stopped.Effect0044Neutral position
No power is transmitted from the
engine to the drive axle. When the
brakes are released, the vehicle can
be moved freely (pushed or towed).
To avoid damage to the
transmission, never shift the
automatic transmission into neutral
position N while driving.
Exception: If the ESP ®
is switched
off or malfunctioning, shift the
automatic transmission into neutral
position N if the vehicle is in danger
of skidding.

for any other reason with the
automatic transmission in
neutral position N can result in
transmission damage that is not
covered by the Mercedes-Benz
