keep in mind that a considerably higher
degree of effort is necessary to brake and
steer the vehicle. Adapt your driving
accordingly. Brakes

WARNING
Make sure not to endanger any other road
users when carrying out braking maneu-
vers.
Refer to the description of the hydraulic
brake assistant (Y page 48).
! Because the ESP ®
operates automati-
cally, the ignition must be switched off
when the parking brake is being tested
on a brake test dynamometer. Active
braking action through the ESP ®
may oth-
erwise seriously damage the brake sys-
tem which is not covered by the smart
Limited Warranty.
Brake pad wear or a leak in the brake system
may be the reason for low brake fluid level
in the brake fluid reservoir.
The brake fluid level in the brake fluid
reservoir may be too low if the brake warn-
ing lamp in the instrument cluster comes
on (Y page 23) although the parking brake
is released.
Have the brake system inspected immedi-
ately. Contact an authorized electric drive
smart center.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
electric drive smart center.
Only install brake pads and use brake fluid
recommended by smart. Inclines G
WARNING
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads.
It can also result in the brakes overheat-
ing, thereby significantly reducing their
effectiveness and your ability to stop the
vehicle in sufficient time to avoid an acci-
dent.
Please observe the following guidelines to
avoid that the permitted maximum speed is
exceeded when driving on downhill grades:
R Do not move the gear selector lever to N.
R Recuperation is limited, if:
-the high-voltage battery is fully
charged or too cold
- the power electronics or the electric
motor is overheated.
When driving down long and steep grades,
do not depress the brake pedal perma-
nently. Depress it in intervals instead to
reduce the vehicle speed.
High and low stresses After hard braking, it is advisable to drive
on for some time, rather than immediately
park, so that the air stream will cool down
the brakes faster.
If your brake system is normally only sub-
jected to moderate loads, you should occa-
sionally test the effectiveness of the
brakes by applying above-normal braking
pressure at higher speeds. This will also
enhance the grip of the brake pads.
G
WARNING
Make sure not to endanger any other road
users when carrying out these braking
maneuvers. 148
Driving instructions>> Operation.

Wet road surface
G
WARNING
After driving in heavy rain for some time
without applying the brakes or through
water deep enough to wet brake components,
the first braking action may be somewhat
reduced and increased pedal pressure may
be necessary to obtain expected braking
effect. Maintain a safe distance from vehi-
cles in front.
To help prevent brake disc corrosion after
driving on wet road surfaces (particularly
salted roads), it is advisable to brake the
vehicle with considerable force prior to
parking. The heat generated serves to dry
the brakes. G
WARNING
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
Limited braking effect on salted roads Remember that the effect of the brakes can
be limited on salted road surfaces. A layer
of salt can form on brake discs and brake
pads, considerably reducing the friction
between the brake disc and the brake pad.
The effect is most noticeable after long
trips without braking, e.g. on the highway,
and after the vehicle has been parked for
several hours.
G
WARNING
The accumulation of salt on brake discs and
brake pads reduces braking effectiveness
and increases the distance necessary to
come to a complete standstill. This could
potentially cause an accident and/or per-
sonal injury.
To avoid this risk, you should
R brake carefully every now and then on
salted roads in order to remove any layer
of salt on the brake disc and brake pad, but do so without endangering any other
road users
R keep a good safe distance from the vehi-
cle in front and drive carefully
R press the brake carefully at the end of the
trip and again when beginning the next
trip in order to remove any salt residues
from the brake disc
New brake pads Only install brake pads recommended by
smart.
G
WARNING
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that
safe braking is substantially impaired.
This could result in an accident. G
WARNING
New brake pads will not achieve their opti-
mal braking effect until after several hun-
dred miles (kilometers). This means that
you must compensate for the reduced brak-
ing effect by pressing harder on the brake
pedal and adapt your driving style accord-
ingly. The same applies after brake pads or
brake discs have been changed. Drive sensibly - save energy
Energy consumption, to a great extent,
depends on driving habits and operating
conditions.
To save energy you should:
R Drive carefully and maintain a suitable
distance from the vehicle in front.
R Avoid frequent acceleration and decel-
eration.
R Keep tires at the recommended inflation
pressures.
R Remove carriers* when not in use. Driving instructions

Problem Possible causes/consequences and
0050
0050Solutions A warning signal
sounds when parking. You have not engaged the parking brake before releasing the
brake pedal and switching off the drive system.
X
Switch on the ignition to deactivate the acoustic warning.
X Engage the parking brake.
X Make sure the gear selector lever is in park position P.
X Turn the key to starter switch position 0.
X Remove the key from the starter switch.
For safety, it is important that you perform the parking pro-
cedure as described (Y page 77).You can hear a contin-
uous noise from the
front axle when brak-
ing. The vehicle is equipped with a mechanical/acoustic brake pad
indicator.
X
Have the brake pads checked at an authorized electric drive
smart center. Unlocking/locking manually
Unlocking the vehicle
You can unlock the driver’s door and the
charge socket flap by unlocking the
driver’s door using the key. The lock cyl-
inder is fitted with a cap.
X Press button 0034on the key.
i For replacing the transmitter battery
(Y page 178). X
Remove cap 0043from lock cylinder 0044.
X Unlock the driver’s door.
The driver’s door and the charge socket
flap are unlocked. i
To unlock the vehicle centrally press
the central unlocking switch in the upper
center console (Y page 27). Locking the vehicle
If you can no longer lock the vehicle using
the remote control and you do not have a
spare transmitter battery at hand, please
proceed as follows:
X Open the driver’s door.
X Press the central locking switch
(Y page 53).
The indicator lamp on the central lock-
ing switch comes on, when the starter
switch is in position 1.
The indicator lamp on the central lock-
ing switch flashes, when the starter
switch is in position 0.
X Remove the key from the starter switch,
take it with you, and close all doors.
The vehicle is now locked. Unlocking/locking manually
