Rthe deformation characteristics of the
vehicle
Rthe characteristics of the object with
which the vehicle has collided
Factors which can only be seen and measured
after a collision has occurred do not play a
decisive role in the deployment of an air bag.
Nor do they provide an indication of air bag
deployment.
The vehicle can be deformed considerably,
without an air bag being deployed. This is the
case if only parts which are relatively easily deformed are affected and the rate of decel-
eration is not high. Conversely, air bags may
be deployed even though the vehicle suffers
only minor deformation. This is the case if,
for example, very rigid vehicle parts such as longitudinal body members are hit, and suf-
ficient deceleration occurs as a result.
If the control unit of the restraint system
detects a side impact or a vehicle rollover,
the relevant components of the restraint sys-
tem are activated separately depending on
the anticipated type of accident.
RThorax/pelvis air bag on the side of
impact, independently of the Emergency
Tensioning Device and the use of the seat
belt
The thorax/pelvis air bag on the front-
passenger side deploys under the following
conditions:
-the OCS system detects that the front-
passenger seat is occupied or
-the belt tongue is engaged in the belt
buckle of the front-passenger seat
RWindow curtain air bag on the side of
impact, independently of the use of the seat
belt and independently of whether the
front-passenger seat is occupied
RWindow curtain air bags on the driver's andfront-passenger side in certain situations
when the vehicle rolls over, if the system
determines that deployment can offer
additional protection to that provided by
the seat belt
REmergency Tensioning Devices, if the sys-
tem determines that deployment can offer
additional protection in this situation
iNot all air bags are deployed in an acci-
dent. The differ ent air bag systems work
independently of each other. How the air bag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or
acceleration and the apparent type of acci-
dent:
RFrontal collision
RSide impact
RRollover
Children in the vehicle
Important safety notes
If a child younger than 12 years and under 5 ft
(1.50 m) in height is traveling in the vehicle:
Ralways secure the child in a child restraint
system suitable for Mercedes-Benz vehi-
cles. The child restraint system must be
appropriate to the age, weight and size of
the child
Rbe sure to observe the instructions and
safety notes in this section in addition to
the child restraint system manufacturer's
installation instructions
Rbe sure to observe the instructions and
safety notes in "Occupant classification
system (OCS)" (
Ypage 36)
GWARNING
If you leave children unsupervised in the
vehicle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of
park position Por shift manual trans-
mission into neutral.
Rstart the engine.
In addition, they may operate vehicle
equipment and become trapped. There is a
risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle.
Never leave children unsupervised in the
vehicle.

Pets in the vehicle
GWARNING
If you leave animals unattended or unse-
cured in the vehicle, they could press but-
tons or switches, for example.
As a result, they could:
Ractivate vehicle equipment and become
trapped, for example
Ractivate or deactivate systems, thereby
endangering other road users
Unsecured animals could also be flung
around the vehicle in the event of an acci- dent or sudden steering or braking, thereby
injuring vehicle occupants. There is a risk
of an accident and injury.
Never leave animals unattended in the
vehicle. Always secure animals properly
during the journey, e.g. use a suitable ani-
mal transport box.
Protection against theft
Immobilizer
The immobilizer prevents your vehicle from
being started without the correct Smart Key.
XTo activate: remove the Smart Key from the
ignition lock.
XTo deactivate: switch on the ignition.
When leaving the vehicle, always take the
Smart Key with you and lock the vehicle. The
engine can be started by anyone with a valid
Smart Key that is left inside the vehicle.
iThe immobilizer is always deactivated
when you start the engine.
In the event that the engine cannot be star-
ted when the starter battery is fully
charged, the immobilizer may be faulty.

Driving safety systems
Overview of driving safety systems
In this section, you will find information
about the following driving safety systems:
RABS (Anti-lock BrakingSystem)
(Ypage 47)
RDistance warning function (Ypage 48)
Resp®(Electronic StabilityProgram)
(Ypage 49)
REBD (Electronic Brake forceDistribution)
(Ypage 50)
Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety sys-
tems can neither reduce the risk of accident
nor override the laws of physics. Driving
safety systems are merely aids designed to
assist driving. You are responsible for the
distance to the vehicle in front, for vehicle
speed and for braking in good time. Always
adapt your driving style to suit the prevail-
ing road, weather and traffic conditions and
maintain a safe distance from the vehicle in
front. Drive carefully.
The driving safety systems described only
work as effectively as possible when there is
adequate contact between the tires and the
road surface. Please pay special attention to
the notes on tires, recommended minimum
tire tread depths, etc. (
Ypage 177).
In wintry driving conditions, always use win-
ter tires (M+S tires) and if necessary, snow
chains. Only in this way will the driving
safety systems described in this section work
as effectively as possible. For safety reasons, smart recommends that you
only use snow chains that have been specially
approved for your vehicle by smart, or fine-
link snow chains that are of a corresponding
standard of quality. For more information,
please contact a qualified specialist work-
shop.
ABS (Anti-lock Braking System)
General information
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 0025 (Canada only) or 00DF(USA only) abs
warning lamp in the instrument cluster lights up when the ignition is switched on. It goes
out when the engine is running.
Important safety notes
iObserve the "Important safety notes" sec-
tion for driving safety systems (Ypage 47).
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (
Ypage 132) and
display messages which may be shown in the
instrument cluster (
Ypage 121).
GWARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety sys-
tems are deactivated. There is an increased
danger of skidding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
abs works from a speed of about 4 mph (6 km/h),
regardless of road-surface conditions. ABS
works on slippery surfaces, even if you only
brake gently.

running, particularly if the vehicle is
moving, exhaust fumes could enter the
passenger compartment. There is a risk of
poisoning.
Turn off the engine before opening the
tailgate. Never drive with the tailgate
open.
GWARNING
If objects, luggage or loads are not secured or not secured sufficiently, they could
slip, tip over or be flung around and
thereby hit vehicle occupants. There is a
risk of injury, particularly in the event of
sudden braking or a sudden change in
direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before
the journey.
!Do not exceed the lower tailgate maximum
load of 220 lbs (100 kg). It may otherwise
become damaged.
!The tailgates swings backwards, upwards
and downwards when opened. Therefore,
make sure that there is sufficient space
above, behind and under the tailgates.
iThe opening dimensions of the tailgate
