82 Safety and SecurityOccupant safetyAutomatic comfort-fit feature seat belt
An automatic comfort-fit feature for front
seats reduces the retracting force of the
seat belts when they are in normal use.
Preventive occupant safety (PRE-SAFE
®)Your vehicle automatically takes preven-
tive measures to better protect the occu-
pants in the following hazardous
situations:


You execute an emergency braking ma-
neuver and the Brake Assist System
(page 92) is activated.


The PRE-SAFE
® system detects a criti-
cal driving dynamics situation.
In such cases, the following systems are
automatically activated:


The front seat belts are pre-tensioned
electrically.


If the vehicle is in a severe skid or is
spinning, the door windows and the
tilt/sliding sunroof close until a small
gap remains.Vehicles with front passenger seat memo-
ry function*:


If the seat is in an unfavorable position,
it will be adjusted to a better position.
If the seat belts do not release:

Adjust the backrest or seat slightly to
the rear until the seat belt tension is di-
minished.
The locking mechanism releases.
Warning!
G
The PRE-SAFE
® system is intended to re-
duce the effects of a crash on properly
seat-belted vehicle occupants. Despite hav-
ing the PRE-SAFE® system in your vehicle,
the possibility of injuries occurring as a re-
sult of an accident cannot be eliminated.
Therefore, you should always drive carefully
and adjust your driving to the prevailing
road, weather, and traffic conditions.
i
If the closing procedure of the tilt/sliding
sunroof or door window is blocked, the tilt/slid-
ing sunroof or door window will stop and open
slightly.
i
The PRE-SAFE
® system is activated in the
previously described circumstances only at
speeds exceeding 20 mph (30 km/h).
When the critical driving dynamic situation has
passed without an accident occurring, the
pre-tensioning on the seat belts is deactivated.
You can then adjust the seat, the door windows
and the tilt/sliding sunroof to their previous po-
sition.

84 Safety and SecurityOccupant safetyChildren in the vehicle
If an infant or child is traveling with you in
the vehicle:
Secure the child using an infant or child
restraint appropriate to the age and
size of the child.

Make sure that the infant or child is
properly secured at all times while the
vehicle is in motion.
Infant and child restraint seats and
information on choosing an appropriate
restraint system can be obtained from any
Mercedes-Benz Center.Infant and child restraint systems
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
Canada only:
Use only a BabySmart
TM compatible child
restraint for the front passenger seat in
this vehicle.
All lap-shoulder belts except the driver’s
seat belt have special seat belt retractors
for secure fastening of child restraints.
To fasten a child restraint, follow child
restraint instructions for mounting. Then
pull the shoulder belt out completely and
let it retract. During seat belt retraction, a
ratcheting sound can be heard to indicate
that the special seat belt retractor is acti-
vated. The seat belt is now locked. Push
down on child restraint to take up any
slack.
To deactivate, release seat belt buckle and
let seat belt retract completely. The seat
belt can again be used in the usual
manner.
Warning!
G
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system. The children could

injure themselves on parts of the vehicle


be seriously or fatally injured through
exposure to extreme heat or cold
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 on these
parts.
If children open a door, they could

injure other persons


get out of the car and injure themselves
or be injured by following traffic
Do not carry heavy or hard objects in the
passenger or cargo compartment unless
they are firmly secured in place. For more in-
formation, see “Loading” (
page 239) and
“Useful features” (
page 244).
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of


strong braking maneuvers

the following driving safety systems:

ABS
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) indepen-
dent of road surface conditions.
On slippery road surfaces, the ABS will
respond even with light brake pressure.The -indicator lamp in the instrument
cluster comes on when you switch on the
ignition. It goes out when the engine is run-
ning.
Braking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating that the ABS is in
the regulating mode.

Keep firm and steady pressure on the
brake pedal while experiencing the pul-
sation.
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 indica-
tion of hazardous road conditions and
functions as a reminder to take extra care
while driving.
Warning!
G
The following factors increase the risk of
accidents:

Excessive speed, especially in turns


Wet and slippery road surfaces


Following another vehicle too closely
The ABS, BAS, ESP
® and Adaptive Brake
cannot reduce this risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
i
In winter operation, the maximum
effectiveness of the ABS, BAS, ESP
® and Adap-
tive Brake is only achieved with winter tires
(
page 327) or snow chains as required.Warning!
G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
the ABS and significantly reduces braking
effectiveness.

When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. It is possible
for children to open a locked door from the
inside, which could result in an accident
and/or serious personal injury.i
When you open a door, the side window on
that side lowers slightly. Once you close the
door, the window moves up again.
!
The side windows will not open or close if
the battery is discharged or the windows are cov-
ered with ice. As a result, you may no longer be
able to properly close the door. Do not attempt
to force the door shut. Doing so may damage the
door or the side window. Correct the condition
that prevents the windows from operating before
attempting to close the door.

Switching fromU to B will briefly
switch off the headlamps. Doing so while
driving in low ambient lighting conditions
may result in an accident.
