R Never place your feet on the instrument
panel, dashboard or on the seat. Always
keep
both feet on the floor in front of the
seat.
R When using a seat belt to secure infant or
toddler restraints or children in booster
seats, always follow the child seat
manufacturer’s instructions. Emergency Tensioning Devices (ETDs)
and seat belt force limiters
The seat belts are equipped with
Emergency Tensioning Devices and seat
belt force limiters.
Emergency Tensioning Devices are
designed to activate in the following
cases:
R in frontal or rear-end impacts
exceeding the system deployment
threshold
R if the restraint systems are operational
and functioning correctly
R in collisions with high vehicle
deceleration/acceleration in the
longitudinal direction, e.g. a head-on
collision
R on passenger side when the seat is
occupied and the seat belt is fastened
R independently of the front air bags
When activated, Emergency Tensioning
Devices
remove slack from the seat belts in
such a way that the seat belts fit more
snugly against the body. Seat belt force
limiters, when activated, reduce the force
exerted by the seat belts on occupants
during a crash.
When the emergency tensioning device is
triggered, the SRS indicator lamp 6 in
the instrument cluster illuminates, see
“SRS indicator lamp” ( Y page 166). G
WARNING
Once they have been triggered, Emergency
Tensioning
Devices will no longer function
properly and must be replaced. smart
recommends that you visit a qualified
workshop to have this done. In particular,
work relevant to safety or on safety-related
systems must be carried out at a qualified
specialist workshop.
Comply with safety regulations when
disposing of Emergency Tensioning
Devices. These regulations are available at
any smart center.
The belt force limiter is designed to
operate in unison with the front air bag,
which absorbs a portion of the seat belt’s
decelerating forces, distributing the load
over a larger area.
In the event of a head-on or rear-end
collision, the emergency tensioning
device is activated if the vehicle is
decelerated or accelerated sufficiently in
the longitudinal direction at the start of
impact with the ignition switched on. Air bags
Air bags can reduce the severity of
injuries in serious collisions, e.g. in a
head-on collision or a side impact. G
WARNING
Air bags are designed to reduce the
potential of injury in certain frontal
impacts (front air bags and knee bags), or
side impacts (head-thorax air bags,
window
curtain air bags and thorax-pelvis
air bags) which may cause significant
injuries. However, no system available
today can completely eliminate injuries
and fatalities.
The deployment of the air bags temporarily
releases a small amount of dust from the air
bags. This dust is neither injurious to your
health, nor does it indicate a fire in the
vehicle. The dust might cause some Occupant safety

Introduction
G
WARNING
The following factors increase the risk of
accidents:
R Excessive speed, especially in turns
R Wet and slippery road surfaces
R Following another vehicle too closely
The driving safety systems described in
this section cannot reduce these risks or
prevent the natural laws of physics from
acting on the vehicle.
Always adapt your driving style to the
prevailing road and weather and traffic
conditions and keep a safe distance to
other road users and objects on the street.
i In winter operation, the maximum
effectiveness of the ABS, the hydraulic
brake assistant, and the ESP ®
is only
achieved with winter tires ( Y page 142)
or snow chains* as required. Antilock Brake System (ABS)
G
WARNING
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.
X Keep 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 X
Keep continuous full pressure on the
brake pedal. G
WARNING
When the ABS is malfunctioning, the
hydraulic brake assistant and the ESP ®
are
also switched off. 46

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 217). 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.
X Apply 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. G
WARNING
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. G
WARNING
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 comes on automatically 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 69) 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.
X Activating: Remove the key from the
starter switch.
X Deactivating: Insert the key in the
starter switch.
X Turn the key to starter switch position 1. Anti-theft warning system*

WARNING
Getting out of your vehicle with the
transmission not fully engaged in park
position P
is dangerous. When the engine is
shut off and the brakes are released, the
vehicle can be moved freely with the gear
selector lever in all positions except park
position P. Also, when parked on an incline,
park position P alone may not prevent your
vehicle from moving, possibly hitting
people or objects.
Always engage the parking brake in
addition to shifting to park position P.
When parked on an incline, always turn the
front wheels towards the curb. G
WARNING
When leaving the vehicle, always remove the
key from the starter switch, take it with
you, and lock the vehicle. Do not leave
children
unattended in the vehicle, or with
access to an unlocked vehicle. Children
could release the parking brake and/or
move the gear selector lever from park
position P, either of which could result in
an accident and/or serious personal
injury.
Brake pedal The brake pedal has two brake circuits
independent
of each other. A brake servo is
used during braking (when the engine is
running) to increase pedal force. G
WARNING
Make sure absolutely no objects are
obstructing the pedals’ range of motion.
Keep the driver’s footwell clear of all
obstacles. If there are any floormats*
or
carpets in the footwell, make sure the
pedals still have sufficient clearance.
During sudden acceleration or braking
maneuvers, the objects could get caught between or beneath the pedals and restrict
your ability to brake or accelerate. This
could lead to accidents and/or injury.
G
WARNING
Considerably more effort will be required
to apply the brakes if
R the brake servo has failed
R a brake circuit has failed
R the engine is switched off, e.g. for
towing the vehicle
The braking distance is likewise greater.
Make sure the engine is running whenever
the vehicle is rolling. Have the brake
system repaired at an authorized smart
center, if there is a fault in the brake
system. If a brake circuit has failed (
Y page 164),
you must depress brake pedal : further
down to achieve the same effect and the
braking distance is increased.
i The
brake servo will only function with
the engine switched on. G
WARNING
In the event of the vehicle needing to be
towed, a significantly greater amount of
pedal pressure will be required when the
engine is switched off. Driving and parking

Driving tips
Accelerator pedal position Your driving style influences the
transmission’s shifting behavior:
Less throttle earlier upshifting
More throttle later upshifting
Kickdown
Use kickdown when you want maximum
acceleration.
X
Press the accelerator pedal past the
point of resistance.
Depending on the engine speed the
transmission shifts into a lower gear.
X Ease up on the accelerator pedal when you
have reached the desired speed.
The transmission shifts up again.
Stopping When you stop briefly, e.g. at traffic
lights:
X
Leave the transmission in gear.
X Hold the vehicle with the brake.
When you stop for a longer period with the
engine idling and/or on a hill:
X Engage the parking brake.
X Move the gear selector lever to park
position P.
Working on the vehicle G
WARNING
When working on the vehicle, engage the
parking brake and move the gear selector
lever to park position P. Otherwise the
vehicle could roll away which could result in an accident and/or serious personal
injury.
Driving on uphill grades Your vehicle has a hill‑start assist system.
G
WARNING
The hill-start assist system is not
designed to function as a parking brake and
does not prevent the vehicle from moving
when parked on an incline.
Always engage the parking brake in
addition to shifting to park position P.
On uphill grades the hill‑start assist
system maintains the pressure in the brake
system for approximately one second after
you have released the brake pedal.
Therefore, you can start off smoothly
without the vehicle moving immediately
after releasing the brake pedal.
X Release the brake pedal.
X Apply sufficient pressure to the
accelerator pedal.
! After approximately one second, the
hill‑start assist system stops braking
the vehicle, which then can roll
backwards. If you open the driver’s door
within this time, the hill‑start assist
system is deactivated and a warning
signal sounds.
i The
hill‑start assist system is inactive
if you start off with the parking brake
engaged. Manual gearshifting
With manual gearshifting M selected,
system-controlled automatic gearshifting
is switched off and you need to change the
gears by upshifting or downshifting
