Useful information
This Operator's Manual describes all models
as well as standard and optional equipment of
your vehicle that were available at the time of
going to print. Country-specific variations are
possible. Note that your vehicle may not be
equipped with all of the described functions.
This also applies to systems and functions rel-
evant to safety.
Read the information on qualified specialist
workshops (Y page
32).Occupant safety
Restraint system introduction
The restraint system can reduce the risk of
vehicle occupants coming into contact with
parts of the vehicle's interior in the event of an
accident. In the event of an accident, the
restraint system can also reduce the forces to
which the vehicle occupants are subjected.
The restraint system includes the following
components:
R Seat belt system
R Air bags
R Child restraint system
R Child seat securing system
The various components of the restraint sys-
tem work complementary to one another. They
can only perform their intended protective
function if all vehicle occupants:
R have correctly fastened their seat belt
( Y page

49)
R have correctly adjusted their seat and head
restraint ( Y page 87)
As the driver, you must also ensure that the
driver's seat is in the correct position in rela-
tion to the pedals and the steering wheel.
Depending on your vehicle's equipment, you
can also adjust the steering wheel. Observe
the information relating to the correct driver's
seat position (Y page 87).
Additionally, you must ensure that an air bag
can deploy freely ( Y page 51).
The air bag is supplementary to a correctly fas-
tened seat belt. As an additional safety device,
the air bag increases the level of protection for
vehicle occupants in the event of an accident.
If the protection provided by the seat belt is sufficient, the air bags do not deploy. Further-
more, in the event of an accident, only air bags
which provide greater protection in the given
accident situation deploy. However, seat belts
and air bags generally do not protect against
objects penetrating the vehicle from the out-
side.
Information on how the restraint system oper-
ates can be found in "Deployment of the Emer-
gency Tensioning Devices and air bags"
( Y page

58).
See "Children in the vehicle" for information
on infants and children traveling with you in
the vehicle restraint systems for infants and
children ( Y page 60). Important safety notes
G
WARNING
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in
an accident or trigger unexpectedly, for
example. This poses an increased risk of
injury or even fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
components or their software.
If it is necessary to modify components of the
restraint system for a person with physical dis-
abilities, contact a Mercedes-Benz Commercial
Van Centerfor details. USA only: contact our
Mercedes-Benz Customer Assistance Center
for details at 1‑877 ‑762‑8267. Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and
at regular intervals while the engine is running.
Therefore, malfunctions can be detected in
good time.
The 6 restraint system warning lamp on
the instrument cluster lights up when the igni-
tion is switched on. It goes out no later than a
few seconds after the vehicle is started. The
restraint system is operational. 46
Occupant safety
Safety

A malfunction has occurred if the
6
restraint system warning lamp:
R does not light up after the ignition is
switched on
R does not go out after a few seconds with the
engine running
R lights up again while the engine is running G
WARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not be trig-
gered as intended in the event of an acci-
dent. This may affect the Emergency Ten-
sioning Devices or air bags, for example.
There is a risk of injury.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop. PASSENGER AIR BAG OFF indicator
lamp
PASSENGER AIR BAG OFF indicator lamp
: is
part of the Occupant Classification System
(OCS).
The PASSENGER AIR BAG OFF indicator lamp
informs you about the status of the co-driver's
air bag.
If the PASSENGER AIR BAG OFF indicator
lamp:
R is lit, the co-driver's air bag is deactivated.
It will not be deployed in the event of an
accident.
R is not lit , the co-driver's air bag is enabled.
If, in the event of an accident, all deploy-
ment criteria are met, the co-driver's air bag
is deployed. Depending on the person in the co-driver's
seat, the co-driver's air bag must be either
deactivated or enabled; see the following
points. You must make sure of this both
before and during a journey.
R Children in a child restraint system:
whether the co-driver's air bag is enabled or
deactivated depends on the installed child
restraint system and the age and size of the
child. It is thus essential to comply with the
instructions on the "Occupant Classification
System (OCS)" ( Y page
54) and "Children
in the vehicle" ( Y page 60). Information is
also included here on rearward or forward-
facing child restraint systems on the co-driv-
er's seat.
R All other persons: depending on the classi-
fication of the person in the co-driver's seat,
the co-driver's air bag must be either ena-
bled or deactivated (Y page 54). Be sure to observe the notes on "Seat belts"
( Y page 47) and "Air bags" (Y page 51).
Information is also included here on the cor-
rect seating position. Seat belts
Introduction A correctly fastened seat belt is the most
effective means of limiting the movement of a
vehicle occupant during a collision or in the
event that the vehicle overturns. This reduces
the risk of vehicle occupants coming into con-
tact with parts of the vehicle interior or being
ejected from it. Furthermore, the seat belt
helps to keep the vehicle occupant in the best
position in relation to a deployed air bag.
The seat belt system consists of:
R seat belts
R Emergency Tensioning Devices for the front
seat belts
The seat belt system includes a belt force
limiter for the respective seat if the vehicle
is equipped with a front air bag.
If the seat belt is pulled quickly or suddenly
from the belt outlet, the inertia reel locks. The
belt strap cannot be pulled out further.
In an impact, the Emergency Tensioning
Device tightens the belt to pull it close to the
body. It does not pull the vehicle occupant Occupant safety

Safety Z

ABS (Anti-lock Braking System)
General notes ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi-
cle when braking.
The ò warning lamp in the instrument clus-
ter lights up when the ignition is switched on.
The lamp goes out when the engine starts run-
ning.
Important safety notes Observe the important safety guidelines for
the driving safety system (
Y page
66).
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface condi-
tions. ABS works on slippery surfaces, even
when you only brake gently. G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of
skidding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
If ABS is malfunctioning, the ò warning
lamp

(Y page 230) lights up while the engine
is running and the display shows a message:
R on vehicles without steering wheel buttons
(Y page 196)
R on vehicles with steering wheel buttons
(Y page 210)
BAS, Hill Start Assist and ESP ®
and its driving
safety systems and other driving systems also
fail. Observe the notes on the ò warning
lamp and the display messages.
Braking If ABS intervenes when braking, you will feel a
pulsating in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions and functions as
a reminder to take extra care while driving. X
If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To make a full brake application: depress
the brake pedal with full force. BAS (Brake Assist System)
General notes BAS operates in emergency braking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes Observe the important safety guidelines for
the driving safety system

(Y page 66). G
WARNING
If BAS is malfunctioning, the braking dis-
tance in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
If BAS is malfunctioning, the ÷ warning
lamp lights up while the engine is running
(Y page

230) and the display shows a mes-
sage:
R on vehicles without steering wheel buttons
(Y page 200)
R on vehicles with steering wheel buttons
(Y page 214)
Braking X
Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. Driving safety systems
67
Safety Z

EBD (electronic brake force distribu-
tion)
General notes EBD monitors and controls the brake pressure
to the rear wheels. This enables EBD to
improve handling during braking.
Important safety notes Observe the important safety guidelines for
the driving safety system
(Y page 66).G
WARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases
the risk of skidding and an accident.
You should therefore adapt your driving
style to the different handling characteris-
tics. Have the brake system checked at a
qualified specialist workshop.
If EBD is malfunctioning, the $ warning
lamp

(Y page 229) lights up while the engine
is running and the display shows a message:
R on vehicles without steering wheel buttons
(Y page 199)
R on vehicles with steering wheel buttons
(Y page 213)
Other driving systems and driving safety sys-
tems then also fail. ESP
®
(Electronic Stability Program)
General notes ESP
®
monitors driving stability and detects a
tendency of the vehicle to understeer or over-
steer (skidding) in good time. If ESP ®
detects
that the vehicle is deviating from the direction
desired by the driver, one or more wheels are
braked to stabilize the vehicle. The engine out-
put is also modified to keep the vehicle on the
desired course within physical limits. ESP ®
can
also stabilize the vehicle during braking.
ESP ®
also monitors traction, i.e. power trans-
mission between the tires and the road sur-
face. The integrated traction control supports
you when pulling away or accelerating on wet,
slippery or slick roads. Should the drive
wheels spin, traction control brakes them indi- vidually. In addition, greater drive torque is
transmitted to the wheel or wheels with trac-
tion. If traction on the road surface is not suffi-
cient, even ESP
®
will not allow you to pull
away without difficulty. The type of tires and
total weight of the vehicle as well as the gradi-
ent of the road also play a crucial role. Trac-
tion control remains active if you deactivate
ESP ®
.
If the h warning lamp in the instrument
cluster goes out before beginning the journey,
ESP ®
is automatically active.
The h warning lamp in the instrument clus-
ter flashes when ESP ®
intervenes:
X do not deactivate ESP ®
under any circum-
stances.
X when driving off, apply as little throttle as
possible.
X adapt your speed and driving style to the
prevailing road conditions.
Important safety notes Observe the important safety guidelines for
the driving safety system (
Y page

66). G
WARNING
If ESP ®
is malfunctioning it will not provide
any vehicle stabilization. There is an
increased risk of skidding or of an accident.
Exercise caution when continuing to drive.
Have ESP ®
checked at a qualified specialist
workshop.
! Do not run the vehicle on a roller dyna-
mometer (e.g. for performance tests). If you
must operate the vehicle on a roller dyna-
mometer, please consult a qualified special-
ist workshop in advance. You could other-
wise damage the drive train or the brake
system.
If ESP ®
is malfunctioning, the h warning
lamp

(Y page 230) lights up continuously
while the engine is running and the display
shows a message.
