The PRE-SAFE
®
system takes preventive
measures to better protect the occupants
from
the possibility of personal injuries in the
following hazardous situations:
R emergency braking situations, e.g. if the
Brake Assist System (BAS) ( Y page 59) is
activated
R critical dynamic driving situations, e.g.
when the vehicle has been caused to
understeer or oversteer because it has
exceeded its physical limitations or in case
of evasive steering maneuvers at speeds
above approximately 85 mph (140 km/h)
The PRE-SAFE ®
system takes the following
measures when it is activated:
R The front seat belts are pre-tensioned
automatically.
R If the front passenger seat is in an
unfavorable position, the seat will be
adjusted to a position that seeks to better
protect the occupant.
R If the vehicle is in a critical dynamic driving
situation, the door windows and the tilt/
sliding sunroof also closes, except for a
minimal gap that remains open.
If the closing procedure of any of these
elements is blocked, it will stop and open
slightly.
Once the hazardous situation no longer exists
and an accident has been avoided, the seat
belt pre-tensioning is deactivated. All of the
PRE-SAFE ®
system settings can be re-
adjusted following the critical driving event.
If the seat belts do not release:
X Adjust the seat backrest or seat slightly to
the rear until the seat belt tension is
reduced.
The locking mechanism releases.
! When moving the seats, make sure there
are no items in the footwell or behind the
seats. Otherwise, you could damage the
seats and/or the items. NECK-PRO active front head
restraints
The NECK-PRO active front head restraints
are intended to offer the driver and front
passenger increased protection from
whiplash-type injuries. In the event of a rear-
end
collision, the NECK-PRO active front head
restraints on the front seats are designed to
move forward in the direction of travel. They
thus provide the head with increased support
earlier on in the collision sequence. The
NECK-PRO active front head restraints will
move forward whether the seats are occupied
or not. G
Warning!
Do not attach any objects (e.g. hangers) to the
head restraint posts. Otherwise, the NECK-
PRO active front head restraints may not be
able

to function properly or offer the intended
degree of protection they were designed for
in the event of a rear-end collision. G
Warning!
Only use seat or head restraint covers which
have
been tested and approved by Mercedes-
Benz for your vehicle model.
Using other seat or head restraint covers may
interfere with or prevent the activation of the
NECK-PRO active front head restraints and/
or the deployment of the front side impact air
bags.
Contact an authorized Mercedes-Benz Center
for availability.
When the NECK-PRO active front head
restraints have been triggered in an accident,
the NECK-PRO active front head restraints
must be reset. Otherwise, the NECK-PRO
active front head restraints cannot offer any
additional protection in the event of another
rear-end collision.
For information on resetting the activated
NECK-PRO active front head restraints, see
“Resetting activated head restraints”

Seat and head restraint
G
Observe Safety notes, see page 77.
X Position seat = and head restraint
properly. See ( Y page 78) for seat and
head restraint adjustment.
Observe the following points:
R Always be in a properly seated position.
R The
position should be as far rearward from
the front air bag in the steering wheel as
possible, while still permitting proper
operation of vehicle controls.
R Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely.
R The seat must be adjusted so that you can
correctly fasten and position your seat belt.
R The seat backrest must be in a position that
is as nearly upright as possible.
R Adjust the seat cushion so that the front
edge of the seat cushion lightly supports
your legs.
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 the seat is being
adjusted. Children in the vehicle
Safety notes If an infant or child is traveling with you in the
vehicle:
X
Secure the child using an infant or child
restraint

appropriate to the age and size of
the child.
X Make sure the infant or child is properly
secured at all times while the vehicle is in
motion. G
Warning!
When leaving the vehicle, always remove the
SmartKey from the starter switch. Always
take the SmartKey with you and lock the
vehicle. Do not leave children unattended in
the

vehicle, even if they are secured in a child
restraint system, 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. The children
could
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
starter switch or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system’s
metal parts, for example, could become very
hot, and the child could be burned by these
parts. G
Warning!
Do not carry heavy or hard objects in the
passenger compartment unless they are
firmly secured in place.
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of
R strong braking maneuvers
R sudden changes of direction
R an accident 52

Introduction
This section contains information about the
following driving safety systems:
R ABS ( Antilock Brake System)
R Adaptive Brake
R BAS ( Brake Assist System)
R EBP ( Electronic Brake Proportioning)
R ESP ®
( Electronic Stability Program)

achieved with winter tires, or snow chains
as required.
Safety notes G
Warning!
The following factors increase the risk of
accidents:
R Excessive speed, especially in turns
R Wet and slippery road surfaces
R Following another vehicle too closely
The driving safety systems described in this
section cannot reduce these risks or prevent
the
natural laws of physics from acting on the
vehicle. They cannot increase braking or
steering efficiency beyond that afforded by
the condition of the vehicle brakes and tires
or the traction afforded.
Only a safe, attentive, and skillful driver can
prevent accidents.
The capabilities of a vehicle equipped with the
driving safety systems described in this
section must never be exploited in a reckless
or dangerous manner which could jeopardize
the user’s safety or the safety of others.
Always adjust your driving style to the
prevailing road and weather conditions and
keep a safe distance to other road users and
objects on the street.
If a driving system malfunctions, other driving
safety systems may also switch off. Observe
indicator and warning lamps that may come
on as well as messages in the multifunction
display that may appear. ABS
G
Observe Safety notes, see page 58. G
Warning!
Do not pump the brake pedal. Use firm, steady
brake pedal pressure instead. Pumping the
brake pedal defeats the purpose of the ABS and significantly reduces braking
effectiveness.
The Antilock Brake System (ABS) regulates
the

brake pressure so that the wheels do not
lock during braking. This allows you to
maintain the ability to steer your vehicle.
The ABS is functional above a speed of
approximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will
respond even to light brake pressure.
The ABS indicator lamp ! in the
instrument cluster comes on when you switch
on the ignition. It goes out when the engine
is running.
Braking At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal. The pulsation indicates that the
ABS is in the regulating mode.
X
Keep firm and steady pressure on the brake
pedal while you feel the pulsation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely

braking power and the ability to steer
the vehicle.
The pulsating brake pedal can be an
indication of hazardous road conditions and
functions as a reminder to take extra care
while driving.
Emergency brake maneuver X
Keep continuous full pressure on the brake
pedal. G
Warning!
If the ABS malfunctions, other driving safety
systems
such as the BAS or the ESP ®
are also
switched off. Observe indicator and warning
lamps that may come on as well as messages
in the multifunction display that may appear. 58
