Children in the vehicle
Safety notes
If an infant or child is traveling with you in the
vehicle:
XSecure the child using an infant or child
restraint appropriate to the age and size of
the child.XMake sure the infant or child is properly
secured at all times while the vehicle is in
motion.GWarning!
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.
GWarning!
Do not carry heavy or hard objects in the
passenger compartment or trunk 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
Infant and child restraint systemsGObserve Safety notes, see page 56.
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.

For information on LATCH-type (ISOFIX)
child seat anchors ( Y page 59).
The use of infant or child restraints is required
by law in all 50 states, the District of
Columbia, the U.S. territories and all
Canadian provinces.
Infants and small children should be seated
in an appropriate infant or child restraint
system. They must be properly secured in
accordance with the manufacturer’s
instructions for the child restraint. All infant
or child restraint systems must comply with
U.S. Federal Motor Vehicle Safety Standards
213 and 225 and Canadian Motor Vehicle
Safety Standards 213 and 210.2.
A statement by the child restraint
manufacturer of compliance with these
standards can be found on the instruction
label on the restraint and in the instruction
manual provided with the restraint.
When using any infant restraint, toddler
restraint, or booster seat, make sure to
carefully read and follow all manufacturer’s
instructions for installation and use.
Please read and observe warning labels
affixed to the inside of the vehicle and to
infant or child restraints.
GWarning!
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children be placed in the rear seats whenever
possible. Regardless of seating position,
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.
The infant or child restraint must be properly
secured with the vehicle’s seat belt, the seat
belt and top tether strap, or lower anchors and
top tether strap, fully in accordance with the
child seat manufacturer’s instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to place a child in the front
passenger seat:
R USA only: Your vehicle is equipped with air
bag technology designed to deactivate the
front passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropriate
child restraint on the front passenger seat.
R USA only: For children larger than the
typical 12-month-old child, the front
passenger front air bag may or may not be
activated. Always make sure the
45 indicator lamp is illuminated,
indicating that the front passenger front air
bag is deactivated.
R Canada only: Children 12 years old and
under must never ride in the front seat,
except in a Mercedes-Benz authorized
BabySmart™ compatible child seat, which
operates with the BabySmart™ system
installed in the vehicle to deactivate the
front passenger front air bag when it is
installed properly. Otherwise they will be
struck by the air bag when it inflates in a
crash. If this happens, serious or fatal injury
will result.Occupant safety57Safety and security212_AKB; 2; 41, en-USd2ureepe,Version: 2.11.8.12009-07-17T09:14:21+02:00 - Seite 57Z
RA child in a rear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to
completely eliminate this risk is to never
place a child in a rear-facing child restraint
in the front seat. We therefore strongly
recommend that you always place a child
in a rear-facing child restraint in a backseat.
R If you must install a rear-facing child
restraint on the front passenger seat
because circumstances require you to do
so, make sure the 45 indicator lamp
is illuminated, indicating that the front
passenger front air bag is deactivated.
Should the 45 indicator lamp not
illuminate or go out while the restraint is
installed, please check installation.
Periodically check the 45 indicator
lamp while driving to make sure the
45 indicator lamp is illuminated. If
the 45 indicator lamp goes out or
remains out, do not transport a child on the
front passenger seat until the system has
been repaired.
A child in a rear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates.
R If you have to place a child in a forward-
facing child restraint on the front passenger
seat, move the seat as far back as possible,
use the proper child restraint
recommended for the age, size and weight
of the child, and secure child restraint with
the vehicle’s seat belt according to the child
seat manufacturer’s instructions.GWarning!
Infants and small children should never share
a seat belt with another occupant. During an
accident, they could be crushed between the
occupant and seat belt.
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.
Children too big for a toddler restraint must
ride in seats using regular seat belts. Position
shoulder belt across chest and shoulder, not
face or neck. A booster seat may be
necessary to achieve proper seat belt
positioning for children over 41 lb (18 kg) until
they reach a height where a lap/shoulder belt
fits properly without a booster.
When the child restraint is not in use, remove
it from the vehicle or secure it with the seat
belt to prevent the child restraint from
becoming a projectile in the event of an
accident.
Installation of infant and child restraint
systemsGObserve Safety notes, see page 56.GWarning!
Always lock the seat backrests in their upright
position when the rear seats are occupied by
passengers. Lock the seat backrests in their
upright position before installing top tether
straps or when the extended cargo
compartment is not in use. Make sure that
seat backrests are secured properly by
pushing and pulling on the seat backrests. If
a seat backrest is not locked properly, the
seat backrest could fold. The child seat would
no longer be supported properly or positioned
to provide its intended benefit. That could
cause serious or even fatal injuries.
This vehicle is equipped with tether
anchorages for a top tether strap at each of
the rear seating positions.
Top tether straps enable an additional
connection to be made between child
restraint systems secured with LATCH-type
(ISOFIX) anchors and rear seats. This can
further reduce the risk of injury.

iIn winter operation, the maximum
effectiveness of most of the driving
systems described in this section is only
achieved with winter tires, or snow chains
as required.
Safety notesGWarning!
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.
ABSGObserve Safety notes, see page 62.GWarning!
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.
XKeep 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
XKeep continuous full pressure on the brake
pedal.62Driving safety systemsSafety and security
212_AKB; 2; 41, en-USd2ureepe,Version: 2.11.8.12009-07-17T09:14:21+02:00 - Seite 62
GWarning!
If the ABS malfunctions, other driving safety
systems such as the BAS or the ESC are also
switched off. Observe indicator and warning
lamps that may come on as well as messages
in the multifunction display that may appear.
If the ABS malfunctions, the wheels may lock
during hard braking, reducing steering
capability and extending the braking distance.
BAS
GObserve Safety notes, see page 62.
The Brake Assist System (BAS) operates in
emergency situations. If you apply the brakes
very quickly, the BAS provides full brake
boost automatically, thereby potentially
reducing the braking distance.
XApply continuous full braking pressure until
the emergency braking situation is over.
The ABS will prevent the wheels from
locking.
When you release the brake pedal, the brakes
function again as normal. The BAS is then
deactivated.
GWarning!
If the BAS malfunctions, the brake system still
functions, but without the additional brake
boost available that the BAS would normally
provide in an emergency braking maneuver.
Therefore, the braking distance may increase.
BAS PLUS
The Brake Assist System PLUS (BAS PLUS)
operates in emergency braking situations and
uses radar sensors to assess the traffic
situation. BAS PLUS assists you in braking at
speeds above approximately 20 mph
(30 km/h).
When traveling in Canada in a vehicle not
registered in Canada, you must switch off the
radar sensor system ( Y page 144). Canadian
law does not permit the use of the radar
sensor system for vehicles from outside of
Canada.
When you switch off the radar system, the
following functions are deactivated:
R BAS PLUS
R PRE-SAFE ®
Brake ( Y page 69)
R DISTRONIC PLUS ( Y page 149)GWarning!
BAS PLUS is a convenience system designed
to assist the driver during vehicle operation.
The responsibility for the vehicle speed and
the distance to the vehicle ahead, including
most importantly brake operation to assure
safe stopping distance, always remains with
the driver.
Always pay attention to traffic conditions
even while BAS PLUS is switched on.
Otherwise, you may not be able to recognize
dangerous situations until it is too late and
could cause an accident. Personal or fatal
injury to you or others may be the result.
i This device has been approved by the FCC
as a “Vehicular Radar System”. The radar
sensor is intended for use in an automotive
radar system only. Removal, tampering, or
altering of the device will void any
warranties, and is not permitted by the
FCC. Do not tamper with, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
BAS PLUS detects obstacles that are in your
driving path for a sufficient period of time to
permit the system to recognize these
obstacles. If you approach the detected
obstacle quickly, BAS PLUS calculates the
level of brake power boost appropriate for the
circumstance to supply when the driver
applies the brakes.
When you step quickly on the brake pedal in
an emergency braking situation, BAS PLUS
automatically regulates the brake power
Driving safety systems63Safety and security212_AKB; 2; 41, en-USd2ureepe,Version: 2.11.8.12009-07-17T09:14:21+02:00 - Seite 63Z
boost to a level that is suitable for the traffic
situation.
If BAS PLUS requires a particularly high brake
power boost, PRE-SAFE ®
is activated at the
same time.XKeep constant pressure on the brake pedal
until the emergency braking situation is
over.
During this process, the ABS prevents the
wheels from locking up.
The brakes will resume normal operation
after
R the brake pedal is released
R no obstacles are detected in your path
R the system no longer senses a risk of a
collision
BAS PLUS is then deactivated.
BAS PLUS can react to stationary obstacles
such as standing or parked vehicles at road
speeds of up to approximately 40 mph
(70 km/h).
BAS PLUS can only assist you when the radar
sensors are switched on and functional. You
can check whether the sensors are active by
switching on DISTRONIC PLUS
( Y page 149) or using the Radar sensors
function in the instrument cluster control
system.
GWarning!
BAS PLUS will only respond with brake
assistance if it has clearly detected an object.
Detection can be impeded by
R dirty or covered sensors
R snowfall or heavy rain
R disturbance from other radar sources
R strong radar reflection such as in parking
garages
BAS PLUS uses radar signals that are not
reflected well by narrow objects and
absorptive materials. For this reason BAS
PLUS will not react to persons, animals, and
approaching traffic or cross-traffic.
BAS PLUS may not detect narrow vehicles
driving in front of you, such as motorcycles
and vehicles driving offset from your vehicle
center.
After a hard collision or damage to the front
of the vehicle from an accident, have the
adjustment and operation of the radar
sensors checked by an authorized Mercedes-
Benz Center.
If BAS PLUS is not available due to a radar
sensor malfunction, the braking system will
continue to function normally with full brake
boost and full standard BAS function.
Adaptive Brake
Adaptive Brake provides a high level of
braking safety as well as increased braking
comfort. Adaptive Brake takes driver and
vehicle characteristics into consideration,
thus achieving an optimal braking effect.
In addiditon, Adaptive Brake provides the
HOLD function (Y page 161) and the hill-start
assist system ( Y page 160).
For more information on the brake system,
see ( Y page 254).
EBP
GObserve Safety notes, see page 62.
The Electronic Brake Proportioning (EBP)
enhances braking effectiveness by allowing
the rear brakes to supply a greater proportion
of the braking effort in straight-line braking
without a loss of vehicle stability.
GWarning!
If the EBP malfunctions, the brake system will
still function with full brake boost. However,
the rear wheels could lock up during
emergency braking situations, for example.
You could lose control of the vehicle and
cause an accident.
Adapt your driving style to the changed
driving characteristics.
