WARNING
When connected to a power supply socket, a
high electrical load during the charging
process can lead to overheating of the
external power supply. There is a risk of
fire.
Find out about the maximum permissible
current load of the external power supply
socket for the respective country at an
authorized electric drive smart center.
Check the maximum permissible charge
current on site before you begin the
charging process. Contact an authorized
electric drive smart center should you
require assistance. If necessary, adjust
the settings of your vehicle.
! An excessive charge current can blow a
fuse or lead to overheating of the
external power supply. Check whether the
external power supply is compatible
with the set charge current. If necessary,
lower the set charge current or use
another power socket. 0002

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. Adapt your driving
accordingly.
Brakes
G
WARNING
Make sure not to endanger any other road
users when carrying out braking
maneuvers.
Refer to the description of the hydraulic
brake assistant (Y page 46).
! Because the ESP ®
operates
automatically, 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 otherwise seriously
damage the brake system 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
warning lamp in the instrument cluster
comes on (Y page 21) although the parking
brake is released.
Have the brake system inspected
immediately. 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 When driving down long and steep grades,
do not depress the brake pedal permanently. Depress it in intervals
instead to reduce the vehicle speed. 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
overheating, thereby significantly
reducing their effectiveness and your
ability to stop the vehicle in sufficient
time to avoid an accident.
High and low stresses After hard braking
,it is advisabl eto 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
subjected to moderate loads, you should
occasionally 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.
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
vehicles 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 142
