59 Safety and Security
Occupant safety
Infant and child restraint systems
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
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. To deacti-
vate the special seat belt retractor for the
front passenger seat, the front passenger
seat must be in the most backward posi-
tion. The seat belt can again be used in the
usual manner.
The use of infant or child restraints is re-
quired by law in all 50 states, the District
of Columbia, the U.S. territories and all Ca-
nadian provinces.
Warning!
G
Do not leave children unattended in the ve-
hicle, even if they are secured in a child re-
straint system. The children could

injure themselves on parts of the vehicle


be seriously or fatally injured through
excessive 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
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of

strong braking maneuvers


sudden changes of direction


an accident
Warning!
G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.i

Fold upholstery cover3 upward.

Turn installation device4 to a vertical
position so that upholstery cover3
does not fold down.

Install child seat according to the man-
ufacturer’s instructions.
A rigid connection is established be-
tween the child seat and the body of
the vehicle.Override switch for rear passenger
compartment
You can disable select functions in the rear
passenger compartment for added safety
(for instance when you have children riding
in the rear passenger compartment).
You can disable the following functions in
the rear passenger compartment:

rear door window operation

Warning!
G
Vehicles with rear power seats*: Never ad-
just the rear seat position after installing the
child restraint. Adjusting the rear seat posi-
tion after installing the child restraint could
damage the child restraint and/or introduce
undesirable slack or tension into the seat
belt and loosen or misposition the child re-
straint, lessening the effectiveness of the
child restraint and thus increasing the
chance or severity of injury in an accident.i

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 ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will re-
spond even to light brake pressure.
The - indicator lamp in the instrument
cluster (
page 28) comes on when you
switch on the ignition (
page 370). It goes
out when the engine is running.
Warning!
G
The following factors increase the risk of ac-
cidents:

Excessive speed, especially in turns


Wet and slippery road surfaces


Following another vehicle too closely
The driving safety systems described in this
section cannot reduce these risks or pre-
vent the natural laws of physics from acting
on the vehicle.
Always adapt your driving style to the pre-
vailing road and weather conditions and
keep a safe distance to other road users and
objects on the street.
i
In winter operation, the maximum effective-
ness of the ABS, Adaptive Brake, BAS,
BAS Plus*, EBP, ESP
® and 4MATIC is only
achieved with winter tires (
page 610), 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.

68 Safety and SecurityDriving safety systemsBraking
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.
Emergency brake maneuver

Keep continuous full pressure on the
brake pedal.For more information, see “Practical hints”
(
page 628).
Adaptive Brake
Adaptive Brake provides a high level of
braking safety as well as increased braking
comfort. It is coupled with ABS, ESP
® and
BAS. Adaptive Brake takes driver and vehi-
cle characteristics into consideration, thus
achieving an optimal braking effect.
Warning!
G
When the ABS is malfunctioning, the BAS,
BAS Plus* and ESP
® are also switched off.
When the ABS is malfunctioning, the wheels
may lock during hard braking, reducing
steering capability and extending the brak-
ing distance.
Warning!
G
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency
beyond that afforded by the condition of the
vehicle brakes and tires or the traction
afforded. The ABS cannot prevent acci-
dents, including those resulting from exces-
sive speed in turns, following another
vehicle too closely, or hydroplaning.
Only a safe, attentive, and skillful driver can
prevent accidents.
The capabilities of an ABS equipped vehicle
must never be exploited in a reckless or dan-
gerous manner which could jeopardize the
user’s safety or the safety of others.

69 Safety and Security
Driving safety systems
Adaptive Brake Lights (S600andS65AMG, USAonly)
The brake lamps flash in quick intervals
while you are braking in order to signal to
cars behind you that

you are braking strongly at a speed of
more than 30 mph (50 km/h)


you are braking with the aid of BAS or
BAS Plus*
If you bring the car to a complete stop by
hard braking at a speed of more than
40 mph (70 km/h), the hazard warning
flasher automatically comes on as soon as
the vehicle is at a standstill. While the vehi-
cle is stationary, the brake lamps are con-
tinuously lit up.
Once you drive faster than 6 mph
(10 km/h) afterward, the hazard warning
flasher goes out.
BAS
The Brake Assist System (BAS) operates in
emergency situations. If you apply the
brakes very quickly, the BAS automatically
provides full brake boost, thereby poten-
tially reducing the braking distance.
Apply 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.
For more information, see “Practical hints”
section (
page 628).
Warning!
G
When the BAS is malfunctioning, the brake
system is still functioning normally, but with-
out the additional brake boost available that
BAS would normally provide in an emergen-
cy braking maneuver. Therefore, the braking
distance may increase.
Warning!
G
The BAS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking efficiency beyond that af-
forded by the condition of the vehicle brakes
and tires or the traction afforded. The BAS
cannot prevent accidents, including those
resulting from excessive speed in turns, fol-
lowing another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful
driver can prevent accidents.
The capabilities of a BAS equipped vehicle
must never be exploited in a reckless or dan-
gerous manner which could jeopardize the
user’s safety or the safety of others.

lows:


While driving off, apply as little throttle
as possible


While driving, ease up on the accelera-
tor


Adapt your speed and driving style to
the prevailing road conditions
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP
® cannot prevent accidents result-
ing from excessive speed.
!
Do not tow with one axle raised.
Otherwise the transfer case can be damaged,
which is not covered by the Mercedes-Benz Lim-
ited Warranty.
!
Performance testing must only be conduct-
ed on a two-axle dynamometer.
Otherwise the transfer case can be damaged,
which is not covered by the Mercedes-Benz Lim-

!
Because the ESP
® operates automatically,
the engine and the ignition must be shut off
(SmartKey in starter switch position0 or1 or
KEYLESS-GO start/stop button* in position0
or1) when the parking brake is being tested on a
brake test dynamometer.
Active braking action through ESP
® may other-
wise seriously damage the front or rear axle
brake system.
Operational tests with the engine running can
only be conducted on a two-axle dynamometer.
Warning!
G
PRE-SAFE
® Brake 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 re-
mains with the driver.


79 Safety and Security
Driving safety systems
When the distance to the forward vehicle is
too small, the distance warning lampl
lights up in the instrument cluster. If you
approach the forward vehicle very quickly,
you will hear a warning tone.
If you do not apply the brakes yourself or
maneuver around a sensed obstacle, the
vehicle will automatically initiate light
braking. PRE-SAFE
® (page 57) is activat-
ed when the distance to the vehicle ahead
at your current speed is so close that
PRE-SAFE
® Brake will not be capable of
slowing the vehicle sufficiently.
Warning!
G
PRE-SAFE
® Brake will only respond with
brake assistance if it has clearly detected an
object. Detection can be impeded by


dirty or covered sensors


snowfall or heavy rain


disturbance from other radar sources


strong radar reflection such as in park-
ing garages
PRE-SAFE
® Brake uses radar signals that
are not reflected well by narrow objects and
absorptive materials. For this reason BAS
Plus will not react to


persons and animals


approaching traffic or cross-traffic
PRE-SAFE
® Brake may not detect narrow ve-
hicles driving in front of you, such as motor-
cycles and vehicles driving offset from your
vehicle center.
Warning!
G
PRE-SAFE
® Brake brakes your vehicle with a
maximum of 13 ft/s
2 (4 m/s
2). This corre-
sponds to about 40% of the maximum decel-
eration ability of your vehicle. This
automatic braking is intended only to ini-
tiate the braking if the driver has not already
done so. The driver must apply the brakes in
order to prevent a collision.
PRE-SAFE
® Brake applies the brake pedal
automatically which results in the brake
pedal moving. Therefore keep driver’s foot
area clear at all times, including the area un-
der the brake pedal. Objects stored in this
area may impair pedal movement which
could interfere with the braking ability of the
PRE-SAFE® Brake.
Do not place your foot under the brake pedal
– your foot could become caught.
