In this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.
The restraint systems are

Seat belts (page 52)

Child restraints (page 57)

Lower Anchors and Tethers for
CHildren (LATCH) (
page 61)
Additional protection potential provide

Supplemental Restraint System (SRS)
with

Air bags (page 42)

Air bag control unit (with crash
sensors)

Emergency Tensioning Device
(ETD) for seat belts (

Although independent systems, their pro-
tective functions work in conjunction with
each other.The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates early detection of malfunctions.
The =indicator lamp in the instrument
cluster (
page 30) comes on when the
ignition is switched on and goes out no lat-
er than a few seconds after the engine has
been started.
The SRS components are in operational
readiness when the =indicator lamp is
not lit when the engine is running.
A malfunction in the system has been
detected if the =indicator lamp:

fails to go out after approximately
4 seconds after the engine was started

does not come on at all

comes on after the engine was started
or while driving

The 59 indicator lamp is lo-
cated on the dashboard to the right of the
instrument cluster.
1Front passenger front air bag off indica-
tor lamp
The 59indicator lamp1 will
be illuminated, except with the SmartKey
removed from the starter switch or with
the starter switch in position0
(
page 337).
If the 59indicator lamp
goes out or remains out, do not trans-
port 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 serious-
ly injured or even killed if the front pas-
senger front air bag inflates.

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 se-
cure child restraint with the vehicle’s
seat belt according to the child seat
manufacturer’s instructions. For
children larger than the typical
12-month-old child, the front passenger
front air bag may or may not be
activated (
page 48).
iDeployment of the driver front air bag does
not mean that the front passenger front air bag
also should have deployed.
The Occupant Classification System (
page 47)
may have determined:

that the seat was empty or occupied by the
weight up to or less than that of a typical
12-month-old child seated in a standard
child restraint – both instances where the
system suppresses deployment of the front
passenger front air bag even though the im-
pact met the criteria and was of sufficient
severity to deploy the driver front air bag.

that the seat was occupied by a small individ-
ual (such as a young teenager or a small
adult) or a child weighing more than the
weight of a typical 12-month-old child in a
standard child restraint – instances where
the system may suppress deployment of the
front passenger front air bag even though
the impact met the criteria and was of suffi-
cient severity to deploy the driver front air
bag.

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.

When the distance to the forward vehicle is
too small, the distance warning lampl
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
® Brake will not be capable of
slowing the vehicle sufficiently.

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.

75 Safety and Security
Driving safety systems
To maintain the proper distance to the ve-
hicle in front of you and thus prevent a
rear-end collision, you must apply the
brakes yourself.
Immediately brake the vehicle to avoid
a collision.
Under no circumstances should the
driver await the intermittent warning
sound before braking. See the follow-
ing warning note.
The intermittent warning sound ceases
and the distance warning lampl
goes out when the necessary distance
to the vehicle ahead is again
established.
Warning!G
PRE-SAFE® Brake brakes your vehicle with a
maximum of 13 ft/s2 (4 m/s2). 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.
Warning!G
An intermittent warning sounds and the dis-
tance warning lampl in the instrument
cluster is illuminated if PRE-SAFE
® Brake
calculates that the distance to the vehicle
ahead and your vehicle’s current speed indi-
cate that PRE-SAFE
® Brake will not be capa-
ble of slowing the vehicle sufficiently to
maintain the preset following distance,
which creates a danger of a collision.
Immediately brake your vehicle to increase
the distance between your vehicle and the
vehicle driving in front of you. The warning
sound is intended as a final caution that you
have not interceded with your own braking
inputs to avoid a potentially dangerous situ-
ation. Do not wait for the operation of the
warning signal to intercede with your own
braking, as that will result in potentially dan-
gerous emergency braking which will not al-
ways result in an impact being avoided.
Tailgating increases the risk of an accident.

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.
