Occupant safety
Introduction
The smart vehicle is equipped with seat
belts and dual stage air bags to protect you
in a crash. However, children can be killed
or seriously injured by an inflating air
bag. Indeed, there is a stronger risk of
serious death or bodily injury when an air
bag deploys on a child positioned in a
rear-facing child seat in the passenger
seat. Because this vehicle has only two
front seats and no backseat, it is limited
as are other two-seat vehicles, in the
extent to which it may restrain children
traveling in the passenger front seat. Many
states have laws against placing children
of certain ages in the front seat of a
vehicle that has both front and back seats.
Those laws make exceptions to permit
children to be restrained in the front seat
of two seat vehicles. Special instructions
and warnings are provided below about
when and if you may restrain a child in the
passenger seat of the smart vehicle. Under
certain circumstances, it is appropriate
for the passenger air bag not to operate
when a child is restrained in a car seat in
the passenger seat, and this vehicle is
equipped with technology to accomplish
this. Please pay very close attention to the
instructions and warnings below,
particularly as they relate to children.
In this section you will learn the most
important facts about the restraint system
components of the vehicle.
The restraint systems are:
R Seat belts ( Y page 31)
R Child restraints ( Y page 41)
Additional protection potential is
provided by:
R
Supplemental Restraint System (SRS)
with
- Air bags ( Y page 33)
- Air bag control unit (with crash
sensors)
- Emergency Tensioning Devices and
seat belt force limiters ( Y page 33)
R Air bag system components with
- Passenger front air bag off indicator
lamp ( Y page 40)
- Passenger seat with
Occupant
Classification System (OCS)
( Y page 37)
Although independent systems, their
protective functions work in conjunction
with each other.
i For information on infants and
children traveling with you in the
vehicle and restraint systems for infants
and children, see “Children in the
vehicle” ( Y page 41).
The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates detection of malfunctions. The
SRS indicator lamp 0081 in the instrument
cluster comes on when the ignition is
switched on and goes out after
approximately four seconds.
The SRS components are in operational
readiness if the SRS indicator lamp 0081
is not lit when the engine is running.
A malfunction in the system has been
detected if the SRS indicator lamp 0081
R fails to go out after approximately 4
seconds after the ignition was switched
on
R does not come on at all
R comes on after the engine was started or
while driving

Passenger front air bag off indicator
lamp
The indicator lamp is located on the
overhead control panel.
Passenger front air bag off indicator
lamp 0046 illuminates when the passenger
front air bag is deactivated.
GWarning!
When the SRS indicator lamp 0081 and the
007F 007B indicator lamp are lit at
the same time, there is a malfunction in the
Occupant Classification System.
In order to ensure proper operation of the
air bag system and OCS:
R Have the system checked as soon as
possible by qualified technicians.
Contact an authorized smart center.
R Sit properly belted in a position that is
as upright as possible with your back
against the seat backrest.
R Do not lean on the armrests or lift
yourself from the seat by using the handle
over the door as this may cause the OCS to
be unable to correctly approximate the
occupant weight category.
R Only have the seat repaired or replaced
by an authorized smart center.
R Read and observe all warnings in this
chapter.
Self-test Occupant Classification
System
After turning the key in the starter switch
to position 1 or 2, the 007F 007B
indicator lamp located in the center
console illuminates. If an adult occupant
is properly sitting on the passenger seat
and the system senses the occupant as being
an adult, the 007F 007B indicator
lamp will illuminate and go out after
approximately 4 seconds.
If the seat is not occupied and the system
senses the passenger seat as being empty,
the 007F 007B indicator lamp will
illuminate and not go out.
GWarning!
If the 007F 007B indicator lamp does
not illuminate immediately after starting
the engine, the system is not functioning.
You must contact an authorized smart center
before seating any child on the passenger
seat.
More information can be found in the
“Practical hints” section ( Y page 159).
GWarning!
Never place anything between seat cushion
and child seat (e.g. pillow), since it
reduces the effectiveness of the Occupant
Classification System. The bottom of the
child seat must make full contact with the
passenger seat cushion. An incorrectly
mounted child seat could cause injuries to
the child in case of an accident, instead of
increasing protection for the child.
Follow the manufacturer’s instructions for
installation of child seats.

Antilock Brake System (ABS)GWarning!
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead.
Pumping the brake pedal defeats the
purpose of the ABS and significantly
reduces braking effectiveness.
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.
On slippery road surfaces, the ABS will
respond even to light brake pressure.
The ABS indicator lamp in the instrument
cluster ( Y page 22) comes on when you
switch on the ignition. It goes out when the
engine is running.
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
regulating the brake pressure.
XKeep firm and steady pressure on the
brake pedal while experiencing the
pulsation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to
steer the vehicle.
A pulsating brake pedal can be an
indication of hazardous road conditions
and functions as a reminder to take extra
care while driving.
Emergency brake maneuver
XKeep continuous full pressure on the
brake pedal.GWarning!
When the ABS is malfunctioning, the
hydraulic brake assistant and the ESP ®
are
also switched off.
When the ABS is malfunctioning, the wheels
may lock during hard braking, reducing
steering capability and extending the
braking distance.GWarning!
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
accidents, including those resulting from
excessive 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
dangerous manner which could jeopardize
the user’s safety or the safety of others.
Electronic Stability Program (ESP ®
)
Your vehicle is equipped with the
Electronic Stability Program (ESP ®
). The
ESP ®
is operational as soon as the engine
is running and it monitors the vehicle’s
traction (force of adhesive friction
between the tires and the road surface) and
handling.
The ESP ®
recognizes when a wheel is
spinning or if the vehicle starts to skid.
By applying brakes to the appropriate
wheel and by limiting the engine output,
the ESP ®
works to stabilize the vehicle. The
ESP ®
is especially useful while driving off
and on wet or slippery road surfaces. The
ESP ®
also stabilizes the vehicle during
braking and steering maneuvers.
The ESP ®
warning lamp 0067 in the
instrument cluster flashes when the ESP ®
is
engaged.
The ESP ®
warning lamp 0067 in the
instrument cluster comes on when you

switch on the ignition. It goes out when the
engine is running.
Depending on the driving situation, the
ESP ®
R reduces the speed
R selectively brakes individual wheels
R equalizes the speed of the driven wheels
R stabilizes the vehicle when braking
R assists you in evasive maneuvers on all
roadsGWarning!
If the ESP ®
warning lamp 0067 in the
instrument cluster flashes, proceed as
follows:
R While driving off, apply as little
throttle as possible.
R While driving, ease up on the accelerator
pedal.
R Adapt your speed and driving style to the
prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP ®
cannot prevent accidents
resulting from excessive speed.
GWarning!
The ESP ®
cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase the traction afforded. The
ESP ®
cannot prevent accidents, including
those resulting from excessive speed in
turns, or hydroplaning. Only a safe,
attentive, and skillful driver can prevent
accidents. The capabilities of an ESP ®
equipped vehicle must never be exploited
in a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others.
! Because the ESP ®
operates
automatically, the engine must be turned
off (ignition switched off) when the
parking brake is being tested on a brake
test dynamometer. Active braking action
through the ESP ®
may otherwise seriously
damage the brake system which is not
covered by the smart Limited Warranty.
i The ESP ®
will only function properly if
you use wheels of the recommended tire
size ( Y page 202).
Hydraulic brake assistant
The hydraulic brake assistant operates in
emergency situations. If you apply the
brakes very quickly, the hydraulic brake
assistant automatically provides full
brake boost, thereby potentially reducing
the braking distance.
XApply 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
hydraulic brake assistant is then
deactivated.
GWarning!
When the hydraulic brake assistant is
malfunctioning, the brake system is still
functioning normally, but without the
additional brake boost that would normally
be provided during an emergency braking
maneuver. Therefore, the braking distance
may increase.
GWarning!
The hydraulic brake assistant cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase
braking efficiency beyond that afforded by
the condition of the vehicle brakes and
tires or the traction afforded. The
hydraulic brake assistant cannot prevent
accidents, including those resulting from
excessive speed in turns, following

another vehicle too closely, or
hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The
capabilities of a hydraulic brake assistant
equipped vehicle must never be exploited
in a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others.
Activating the hazard warning flasher
after an emergency braking maneuver
If you bring the vehicle to a complete stop
by strongly braking at a speed of more than
43 mph (70 km/h), the hazard warning
flasher automatically comes on as soon as
the vehicle is at a standstill. The hazard
warning flasher will remain on until it is
switched off using the hazard warning
flasher switch ( Y page 66) or until the
speed of the vehicle has exceeded 6 mph
(10 km/h).
Anti-theft systems
Electronic immobilizer
The electronic immobilizer prevents
unauthorized persons from starting your
vehicle.
When leaving the vehicle, always take the
key with you and lock the vehicle. The
engine can be started by anyone with a key
that is left inside the vehicle.
XActivating: Remove the key from the
starter switch.XDeactivating: Insert the key in the
starter switch.XTurn the key to starter switch position 1.Anti-theft warning system*
Once the anti-theft warning system has
been armed, a visual and audible alarm is
triggered when
R someone opens a door or the tailgate
R someone enters the vehicle’s interior
R there is motion inside the vehicle
R someone attempts to raise the vehicle
The alarm will also be triggered when
unlocking and opening the driver’s door
with the key.
i The alarm will stay on, even if the
driver’s door is immediately closed. For
canceling the alarm, see ( Y page 48).
Close the windows and the tailgate before
arming the alarm system. Make sure there
are no moving objects inside the vehicle.XArming: Lock the vehicle using the
remote control.
