WARNING
A vehicle with an electric motor produces
significantly lower noise levels than a
vehicle with a combustion engine. Other
motorists or pedestrians, especially those who are visually or hearing impaired, may
be unable to hear your vehicle while it is in
motion. This is particularly true when
driving at lower speeds and during parking
maneuvers. At all times, it is the respon-
sibility of the driver to be aware of their
surroundings, especially in these low
speed situations. Otherwise other road
users could be seriously or fatally injured.
Vehicles equipped with an Acoustic Vehi-
cle Indication* emit a certain noise. Thus,
your vehicle will be better noticed by other
road users at low speeds (Y page 48).

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 chil- dren 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. When the igni-
tion is switched on, a brake servo is used
during braking 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 ped- als still have sufficient clearance.
During sudden acceleration or braking
maneuvers, the objects could get caught
between or beneath the pedals and restrictyour ability to brake or accelerate. This
could lead to accidents and/or injury. G

cooling period of at least 30 minutes. Oth- erwise, you could be seriously burned if hot coolant escapes.
The coolant is a mixture of water and anti-
corrosion/antifreeze. To check the coolant
level the vehicle must be parked on level
ground and the drive system must have
cooled down. For more information, see
„Coolants“ (Y page 219).

G
WARNING
During vehicle operation, the boiling
point of the brake fluid is continuously
reduced through the absorption of moisture from the atmosphere. Under extremely
strenuous operating conditions, this mois-
ture content can lead to the formation of
bubbles in the system, thus reducing the
system’s efficiency.
Therefore, the brake fluid must be replaced regularly. Refer to your vehicle’s Mainte-
nance Booklet for replacement interval.
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.
! If you find that the brake fluid in the
brake fluid reservoir has fallen to the
minimum mark or below, have the brake
system checked for brake pad thickness
and leaks immediately. Contact an
authorized electric drive smart center
immediately. Do not add brake fluid as
this will not solve the problem.
X Remove the service flap and insert it on

WARNING
Winter tires with a tread depth of less than 1 / 6 in (4 mm) must be replaced. They are no
longer suitable for winter operation.
Always use winter tires at temperatures
below 45 ¦(7¥) and whenever wintry road
conditions prevail. Not all M+S rated tires provide special winter performance. Make
sure the tires you use show the mountain/
snowflake marking ion the tire side-
wall. These tires meet specific snow trac-
tion performance requirements of the Rub- ber Manufacturers Association (RMA) and
the Rubber Association of Canada (RAC) and
have been designed specifically for use in
snow conditions. Use of winter tires is the only way to achieve the maximum effective-
ness of the ABS and ESP ®
in winter opera-
tion.
For safe handling, make sure all mounted
winter tires are of the same make and have
the same tread design.
For information on winter tires for your
vehicle model, see the "Technical data"
section (Y page 216).
Always observe the speed rating of the win-
ter tires installed on your vehicle. If the
maximum speed for which your tires are
rated is below the speed rating of your
vehicle, you must place a notice to this
effect where it will be seen by the driver.
Such notices are available at your tire
dealer or any authorized electric drive
smart center. Snow chains*
! Remember that snow chains must always
be compatible with the tire sizes of a
vehicle. Snow chains that are approved
by smart are only permitted for the fol-
lowing tire size:

For safety reasons, smart recommends
that you only use snow chains that have
been approved by smart.
Information on this is available from any
smart center.
Please refer to the separate operating
instructions for detailed information on mounting the snow chains.
Snow chains should only be driven on
snow-covered roads at speeds not to
exceed 30 mph (50 km/h). Remove chains
as soon as possible when driving on roads
without snow.
Please observe the following guidelines
when using snow chains: R Using snow chains is not permissible
with all wheel/tire combinations
(Y page 216).
R Use snow chains in pairs and on rear
wheels only. Follow the manufacturer’s
mounting instructions.
R Use of snow chains may be prohibited
depending on location. Always check
local and state laws before mounting
snow chains. G
WARNING
When mounting or removing snow chains,
always park your vehicle on level ground,
engage the parking brake, and switch off
the drive system. The vehicle could other-
wise move and injure yourself or other road users. G
WARNING
When mounting and removing snow chains,
ensure that you and your vehicle are at a
safe distance from moving traffic. Not
doing so could endanger other road users or even lead to you being injured by the vehi-cles behind you. G
WARNING
The vehicle’s handling changes when driv-
ing with snow chains on any kind of road
surface. This means that you should always adapt your driving style to suit the current
road and weather conditions.
! If snow chains that do not meet require-
ments are mounted, they may scrape
against the body or axle components when the vehicle is in motion. This could
result in damage to the rim/tire or vehi-
cle. Driving instructions
