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 140)
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 BrakeSystem (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
drive system is active.
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. 44

accident and/or serious personal injury.
! To prevent possible malfunction, avoid
exposing the remote control to high
levels of electromagnetic radiation.
If you can no longer lock or unlock the
vehicle with the remote control, the
batteries in the remote control are discharged, or the remote control is
malfunctioning.

When loading, make sure no sharp objects
come into contact with the soft top or the
rear window.
Do not place any evenly distributed loads
with a weight of more than 165 lbs (75 kg)
on the rear soft top when folded down.
Make sure the high-mounted brake lamp
is not concealed.
! Do not block the soft top system’s
locking apertures.
Only place the side rails in the
designated storage space of the tailgate.
! Do not sit on the folded-down rear soft
top.
Do not fold down the rear soft top at
temperatures below 14¦ (-10¥).
Do not place any pointed, sharp-edged,
hot (above 176 ¦[80¥]), incandescent or
burning objects on the soft top’s lining.
Do not apply wax to the soft top fabric and
select only wax-free washing products
when using an automatic car wash.
Only drive with the retaining clips
closed, as exhaust fumes could otherwise
reach the vehicle’s interior.
! Please keep in mind that weather
conditions can sometimes change
rapidly. Make sure to close the
retractable soft top and the rear soft top
when leaving the vehicle. If water enters
the vehicle interior, vehicle
electronics could be damaged which is
not covered by the smart Limited
Warranty. Opening and closing the retractable
soft top
You can open and close the retractable soft
top when the vehicle is either stationary
or in motion. G
WARNING
Never operate the retractable soft top if
there is the possibility of anyone being
harmed by the opening or closing
procedure. G
WARNING
The retractable soft top is made out of
fabric. In the event of an accident, the
fabric may tear. This may result in an
opening in the roof.
In a vehicle rollover, occupants not
wearing their seat belts or not wearing
them properly may be thrown out of the
opening. Such an opening also presents a
potentia lfor injury for occupants wearing
their seat belts properly as entire body
parts or portions of them may protrude from
the passenger compartment. 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. A child’s
unsupervised access to a vehicle could
result in an accident and/or serious
personal injury.
! To avoid damaging the seals, do not
transport any objects with sharp edges
which can stick out of the retractable
soft top.
Do not open the retractable soft top if
there is snow or ice on the roof, as this
could result in malfunctions.
If you cannot open or close the
retractable soft top due to a malfunction
contact Roadside Assistance or an
authorized electric drive smart center.

WARNING
Do not turn off the drive system before the
vehicle has come to a complete stop. With
the drive system not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to
keep in mind that a considerably higher
degree of effort is necessary to brake and
steer the vehicle.

G
WARNING
The operating condition of the high-
voltage battery (e.g. not yet at normal
operating temperature or fully charged)
influences the braking effect of the
electric motor.
In overrun or braking mode, the motor's
braking effect may therefore be reduced or
may not be present at all.
As a result of the reduced engine braking
effect, you may cause an accident and
injure yourself or others. Transmission
77>> Controls.
* optional Z
Compensate for the reduced engine braking
effect by pressing the brake pedal
accordingly, as required.
Using the steering wheel paddle shifters,
you can increase or decrease the
recuperation in overrun phases.
Recuperation means that energy is
recovered while driving - the electric
motor functions as a generator. The kinetic
energy of the vehicle is converted into
electric power and stored in the high-
voltage battery. The more the recuperation
increases, the more the vehicle will be
decelerated.
In overrun phases, there are three levels of
recuperation:
R no recuperation (level 0, coasting)
R mid-level recuperation (level 1)
R high-level recuperation (level 2)
The amount of recuperation in overrun
mode is displayed in the power gauge
(Y page 79).
When you switch on the ignition, level 1 is
automatically preset. X
Decrease recuperation: Pull left
steering wheel paddle shifter 0002.
X Increase recuperation: Pull right
steering wheel paddle shifter 0003.Use the different levels 0 to 2 for
conditions as described below: Level 0 Driving without frequent
breaking. No sharp bends on
the road ahead.
Maximum kinetic energy
remains for the vehicle.
Level 1 Normal driving, standard
setting.
Level 2 Sporty driving.
The break pedal has to be
depressed less often, as the
deceleration due to
recuperation is higher than
in level 1.
The energy efficiency is
substantially higher than if
the vehicle is decelerated by
depressing the brake pedal.
At levels
1and 2the vehicle can be
steplessly decelerated by depressing the
brake pedal.
i Under certain circumstances, in
overrun phases recuperation does not
work as described above. This may be e. g
the case if the high-voltage battery is
already fully charged or has not reached
operating temperature. Driving tips

WARNING
The hill-start assist system is not
designed to function as a parking brake and
does not prevent the vehicle from moving
