Smart fortwo coupe and smart fortwo cabriolet (2019). Manual

seat manufacturer’s instructions. For
children larger than the typical
12‑month‑old child, the passenger front
air bag may or may not be activated.

Warning!

Infants and small children should never
share a seat belt with another occupant.
During an accident, they could be crushed
between the occupant and seat belt.
A child’s risk of serious or fatal injuries
is significantly increased if the child
restraint are not properly secured in the
vehicle and/or the child is not properly
secured in the child restraint.
Children too big for a toddler restraint
must ride in a seat using regular seat belt.
Position shoulder belt across chest and
shoulder, not face or neck. A booster seat
may be necessary to achieve proper seat
belt positioning for children over 41 lbs
until they reach a height where a lap-
shoulder belt fits properly without a
booster.
When the child restraint is not in use,
remove it from the vehicle or secure it with
the seat belt to prevent the child restraint
from becoming a projectile in the event of
an accident.
Do not leave children unattended in the
vehicle, even if the children are secured in
a child restraint system. Unsupervised
children in a child restraint system may
use vehicle equipment and may cause an
accident and/or serious personal injury.

If you are using a rear-facing child
restraint system on the passenger seat, you
must verify that the passenger front air bag
is deactivated. When the passenger front
air bag is deactivated, the
40 indicator lamp is
illuminated (

page 42).

Top tether
Top tether permits an additional
connection between a child restraint
system and the passenger seat. Proper
usage of the top tether, in accordance with
instructions provided by the child
restraint manufacturer, can further reduce
the risk of injuries.
The top tether anchorage is located on the
floor of the cargo compartment. The top
tether guide for the top tether strap is
located above, on the head restraint.

Driving safety systems

Introduction

Warning!

The following factors increase the risk of
accidents:

Excessive speed, especially in turns

Wet and slippery road surfaces

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.

In winter operation, the maximum

effectiveness of the ABS, the hydraulic
brake assistant, and the ESP

is only

achieved with winter tires (

page 136)

or snow chains* as required.

Antilock Brake System (ABS)

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 (

page 24) 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.

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

Keep continuous full pressure on the
brake pedal.

Warning!

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.

Warning!

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 d in the

instrument cluster flashes when the ESP

engaged.
The ESP

warning lamp d 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

reduces the speed

selectively brakes individual wheels

equalizes the speed of the driven wheels

stabilizes the vehicle when braking

assists you in evasive maneuvers on all
roads

Warning!

If the ESP

warning lamp d in the

instrument cluster flashes, proceed as
follows:

While driving off, apply as little
throttle as possible.

While driving, ease up on the accelerator
pedal.

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.

Warning!

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.

The ESP

will only function properly if

you use wheels of the recommended tire
size (

page 206).

Driving safety systems

>> Safety.

-------------------------------------------------------------------------------------------------------------------------------------------------------------

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.

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.

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.

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 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 (

page 70) or until the

speed of the vehicle has exceeded 6 mph
(10 km/h).

Safety notes

Warning!

All seat adjustments, as well as fastening
of seat belts, must be done before the
vehicle is operated.

Warning!

When adjusting the seat, make sure no one
becomes trapped.
Do not adjust the driver’s seat while
driving. Adjusting the seat while driving
could cause the driver to lose control of the
vehicle.
Never ride in a moving vehicle with the seat
backrest in an excessively reclined
position as this can be dangerous. You
could slide under the seat belt in a
collision. If you slide under the seat belt,
it could apply force at the abdomen or neck,
potentially causing serious or fatal
injuries. The seat backrest and seat belts
provide the best restraint when the wearer
is in a position that is as upright as
possible and seat belts are properly
positioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt.
Observe the following points:

Adjust the seat backrest until your arms
are slightly angled when holding the
steering wheel.

Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The
position should be as far to the rear as
possible, consistent with ability to
properly operate controls.

Never place hands under the seat or near
any moving parts while a seat is being
adjusted.

Failure to do so could result in an accident
and/or serious personal injury.
