OCS is malfunctioning.
XMake sure there is nothing between the seat cushion and the
child seat.
XMake sure that the entire base of the child restraint system rests
on the seat cushion of the front-passenger seat. The backrest of
the forward-facing child restraint system must lie as flat as
possible against the backrest of the front-passenger seat. If
necessary, adjust the position of the front-passenger seat.
XWhen installing the child restraint system, make sure that the
seat belt is tight. Do not pull the seat belt tight using the front-
passenger seat adjustment. This could result in the seat belt and
the child restraint system being pulled too tightly.
XCheck for correct installation of the child restraint system.
XMake sure that no objects are applying additional weight onto
the seat.
XIf the PASSENGER AIR BAG OFF indicator lamp remains off and/or
the PASSENGER AIR BAG ON indicator lamp lights up, do not
install a child restraint system on the front-passenger seat.
XHave the OCS checked at a smart center as soon as possible.
Deployment of belt tensioners and air
bags
Important safety notes
GWARNING
The air bag parts are hot after an air bag
has been deployed. There is a risk of
injury.
Do not touch the air bag parts. Have a
deployed air bag replaced at a qualified
specialist workshop as soon as possible.
GWARNING
A deployed air bag no longer offers any
protection and cannot provide the intended
protection in an accident. There is an
increased risk of injury.
Have the vehicle towed to a qualified spe-
cialist workshop in order to have a
deployed air bag replaced.
For your own safety and that of your front
passenger, it is important that you have
deployed air bags replaced and faulty air
bags repaired. This will help to make sure the
air bags continue to perform their protective
function for the vehicle occupants in the
event of a crash.

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.

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.

Braking
XIf ABS intervenes:continue to depress the
brake pedal vigorously until the braking
situation is over.
XTo make a full brake application: depress
the brake pedal with full force.
If abs intervenes when braking, you will feel
a pulsing in the brake pedal.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions, and func-
tions as a reminder to take extra care while
driving.
Forward collision warning
General information
The distance warning function can help you to
minimize the risk of a collision with a vehi-
cle ahead or reduce the effects of such an
accident. If the distance warning function
detects that there is a risk of a collision, you
will be warned visually and acoustically.
Starting the engine also switches on the dis-
tance warning function.
Important safety notes
GWARNING
The distance warning function does not
react:
Rto people or animals
Rto oncoming vehicles
Rto crossing traffic
Rwhen cornering
Thus, the distance warning function cannot
provide a warning in all critical situa-
tions. There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
GWARNING
The distance warning function cannot
always clearly identify objects and com-
plex traffic situations.
In such cases, the distance warning func-
tion may:
Rgive an unnecessary warning
Rnot give a warning
There is a risk of an accident.
Always pay careful attention to the traffic
situation and do not rely solely on the dis-
tance warning function.
Observe the "Important safety notes" section for driving safety systems (
Ypage 47).
In particular, the detection of obstacles can
be impaired if:
Rthere is dirt on the sensors or anything else
covering the sensors.
Rsnow or heavy rain
Rinterference by other radar sources
Rthe possibility of strong radar reflec-
tions, for example in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different
line
Rnew vehicles or after a service on the dis-
tance warning system
Please observe the information in the sec-
tion on running-in the vehicle
(
Ypage 86).
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at low speeds where there is no visible
damage to the front of the vehicle.

Overview of climate control systems
General notes
Observe the settings recommended on the fol- lowing pages. The windows could otherwise
fog up.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only
briefly
Rswitch on the cooling with air dehumidi-
fication function
Rswitch on the defrost windshield function
briefly, if required
Automatic climate control regulates the tem-
perature and the humidity of the vehicle
interior. It also filters undesirable substan-
ces out of the air.
Automatic climate control is only available
when the engine is running. Optimum opera-
tion is only achieved with the side windows
closed.
iWhen the weather is warm, ventilate the
vehicle for a brief period. This will speed up the cooling process, and the desired
vehicle interior temperature will be
reached more quickly.
iThe integrated filter filters out most
particles of dust and pollen. It also
reduces odors. A clogged filter reduces the
amount of air supplied to the vehicle inte-
rior. For this reason, you should always
observe the interval for replacing the fil- ter, which is specified in the Maintenance
Booklet. As it depends on environmental conditions, e.g. heavy air pollution, the
interval may be shorter than stated in the
Maintenance Booklet.

tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgment.
The possibility of a serious or even fatal
accident is greatly increased when you
drink or take drugs and drive.
Do not drink or take drugs and drive or
allow anyone to drive who has been drinkingor taking drugs.
Emission control
GWARNING
Combustion engines emit poisonous
exhaust gases such as carbon monoxide.
Inhaling these exhaust gases leads to poi-
soning. There is a risk of fatal injury.
Therefore never leave the engine running
in enclosed spaces without sufficient ven- tilation.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with
the manufacturer's specifications. There-
fore, only allow qualified and authorized
technicians to perform work on the engine.
The engine settings must not be changed
under any circumstances. Furthermore, all
specific service work must be performed at
regular intervals and in accordance with
smart service requirements. Details can be
found in the Maintenance Booklet.
Braking
Important safety notes
GWARNING
If you shift down on a slippery road surface
in an attempt to increase the engine's
braking effect, the drive wheels could lose
their grip. There is an increased danger of
skidding and accidents.
Do not shift down for additional engine
braking on a slippery road surface.
Downhill gradients
!On long and steep gradients, you must
reduce the load on the brakes by shifting to
a lower gear in good time. This allows you
to take advantage of the engine's braking
effect. This helps you to avoid overheating
the brakes and wearing them out exces-
sively.
When you take advantage of the engine's
braking effect, a drive wheel may not turn
for some time, e.g. on a slippery road sur-
face. This could cause damage to the drive
train, which is not covered by the smart
warranty.
Heavy and light loads
GWARNING
If you rest your foot on the brake pedal
while driving, the braking system can
overheat. This increases the stopping dis-
tance and can even cause the braking system
to fail. There is a risk of an accident.
Never use the brake pedal as a footrest.
Never depress the brake pedal and the
accelerator pedal at the same time.
!Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately.
Drive on for a short while. This allows the
airflow to cool the brakes more quickly.
Wet roads
If you have driven for a long time in heavy
rain without braking, there may be a delayed
reaction from the brakes when braking for the
first time. This may also occur after the vehi-
cle has been washed or driven through deep
water.
You then have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the
vehicle washed, brake firmly while paying
attention to the traffic conditions. This will warm up the brake discs, thereby drying them
