Occupant safety
Preventive occupant safety
(PRE-SAFE®)
Your vehicle automatically takes preven-
tive measures to better protect the occu-
pants in the following hazardous
situations.PRE-SAFE
® takes action in the following in-
stances:

Emergency braking maneuver and the
Brake Assist System (BAS) (
page 66)
is activated
or when
BAS Plus* (
page 67) is strongly inter-
vening.

Critical dynamic driving situations, e.g.
when the vehicle is understeering or
oversteering because it has exceeded
its physical limitations.

Evasive steering maneuvers at speeds
above 20 mph (30 km/h).
When you are driving faster than 20 mph
(30 km/h), PRE-SAFE
® takes the following
measures in such situations:

If the OCS senses that the front pas-
senger seat is occupied and the seat is
in an unfavorable position, it will be
adjusted to a better position.

The system increases the air pressure
in the air pockets (on the sides of the
seat cushion and backrest) of the
drive-dynamic multicontour front
seats*.

If the vehicle is understeering or over-
steering, the tilt/sliding sunroof and
the front side windows also close until
only a small gap remains.
Once the hazardous situation is over with-
out an accident occurring, PRE-SAFE
® de-
creases the air pressure in the air pockets
of the drive-dynamic multicontour front
seats*. You can readjust all of the settings
made by PRE-SAFE
®.
Warning!G
The PRE-SAFE® system is intended to re-
duce the effects of an accident on properly
seat-belted vehicle occupants. Despite
having the PRE-SAFE
® system in your vehi-
cle, the possibility of injuries occurring as a
result of an accident cannot be eliminated.
Therefore, you should always drive carefully
and adjust your driving to the prevailing
road, weather, and traffic conditions.
iIf the closing procedure of the tilt/sliding
sunroof or door windows is blocked, the tilt/slid-
ing sunroof or door windows will stop and open
slightly.

Children 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 the infant or child is
properly secured at all times while the
vehicle is in motion.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 seat belt out completely
and let it retract. During seat belt retrac-
tion, a ratcheting sound can be heard to in-
dicate that the special seat belt retractor is
activated. 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.
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

Driving safety systems
This section contains information about
Adaptive Brake Lights as well as the follow-
ing driving safety systems:

ABS (Antilock Brake System)

Adaptive Brake

BAS (Brake Assist System)

BAS Plus* (Brake Assist System Plus)

EBP (Electronic Brake Proportioning)

ESP® (Electronic Stability Program)

PRE-SAFE® Brake* (Preventive Occu-
pant Safe
ty Brake)
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 30) comes on when you
switch on the ignition (
page 336). 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.
iIn winter operation, the maximum effective-
ness of the ABS, Adaptive Brake, BAS,
BAS Plus*, EBP and ESP
® only achieved with
winter tires (
page 549), or snow chains as re-
quired.
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.

65 Safety and Security
Driving safety systems
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.
Emergency brake maneuver
Keep continuous full pressure on the
brake pedal.For more information, see “Practical hints”
(
page 566).
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.

Adaptive Brake Lights (CL 600 and
USA only)
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 566).
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.

PRE-SAFE® Brake* (vehicles with
DISTRONIC Plus* only)
PRE-SAFE
® Brake* can assist you in mini-
mizing the risk of a rear-end collision with
a vehicle in front of you and in reducing the
severity of an accident. At speeds over ap-
proximately 20 mph (30 km/h), it will

warn you of a possible collision

automatically begin to brake the vehi-
cle lightly in a speed range of up to
112 mph (180 km/h)

activate preventative occupant safety
measures (PRE-SAFE®) (page 56)PRE-SAFE
® Brake will only assist you by
automatically initiating braking if the driver
and front passenger have their seat belts
fastened.
Using the radar sensors, PRE-SAFE
® Brake
detects obstacles that are in your driving
path for a sufficient period of time for the
system to recognize it. If you approach a
vehicle and PRE-SAFE
® Brake has estab-
lished that 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, the sys-
tem will initially warn you visually and
acoustically.
When travelling in Canada in a vehicle not
registered in Canada, you must switch off
the radar sensor system* (
page 272). Canadian law does not permit the use of
the radar sensor system* (
page 272) for
vehicles from outside of Canada. When you
switch off the radar sensor system*, the
following functions are deactivated:

BAS Plus* (page 67)

DISTRONIC Plus* (page 411)

Park Assist* (page 435)

PRE-SAFE® Brake
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.
Always pay attention to traffic conditions
even while PRE-SAFE® Brake is switched on.
Otherwise, you may not be able to recognize
dangerous situations until it is too late and
could cause an accident resulting in person-
al or fatal injury to you or others.

comes on 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 56) is activat-
ed when the distance to the vehicle ahead
at your current speed is so close that
PRE-SAFE

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.

Driving safety systems
PRE-SAFE® Brake can react to stationary
obstacles such as standing or parked vehi-
c le s a t roa d s pe eds of up to ap proxim a tel y
40 mph (70 km/h).
Activating and deactivating: Activate
or deactivate PRE-SAFE® Brake using
the instrument cluster control system
(
page 268).
After the function has been activated,
indicator : appears on the
left-hand side of the multifunction dis-
play.PRE-SAFE
® Brake does not always clearly
interpret complex traffic situations. If a vi-
sual and/or acoustic warning is issued in
an uncritical driving situation, or if the ve-
hicle brakes lightly, you can interrupt the
PRE-SAFE
® Brake maneuver by

pressing down all the way on the accel-
erator or using kickdown

releasing the brake pedal
The PRE-SAFE
® Brake maneuver is termi-
nated immediately when

you avoid the obstacle by evasive
steering

you drive less than 9 mph (15 km/h)

an obstacle can no longer be identified
ahead of you

the system no longer senses the risk of
a collisionAfter a hard collision or damage to the
front of the vehicle from an accident, have
the settings and operation of the radar
sensors checked by an authorized
Mercedes-Benz Center.
Warning!G
If you do not receive visual or acoustic warn-
ing signals, PRE-SAFE® Brake has either not
recognized the collision risk, has been deac-
tivated or is malfunctioning. Apply the
brakes yourself to avoid a collision.
iPRE-SAFE® Brake will remain passive while
DISTRONIC Plus* is switched on (

Notes about handling CDs/DVDs

Only hold discs by the edge.

Handle discs carefully to prevent play-
back problems.

Avoid getting scratches, fingerprints
and dust on discs.

Clean discs from time to time with a
commercially-available cleaning cloth.
Do not wipe them with a circular mo-
tion, but only in straight lines from the
center outwards.

Only use a pen designed for such a pur-
pose to label discs.

Place discs back in their boxes after
use.

Protect discs from heat and direct sun-
light.

Warning!G
Only insert a CD or DVD when the vehicle is
stationary. There is a risk of accident by be-
ing distracted from road and traffic condi-
tions if you load a CD/DVD while the vehicle
is in motion.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
iIf the CD/DVD has a printed side, this must
face upwards when the CD/DVD is inserted. If
neither side is printed, the side to be played
should face downwards.
iEach magazine tray button3 indicates the
status of the corresponding magazine tray by
means of an LED.
