WARNING
During vehicle operation, the boiling
point of the brake fluid is continuously
reduced through the absorptio nofmoisture
from the atmosphere. Under extremely
strenuous operating conditions, this
moisture 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
Maintenance Booklet for replacement
interval.
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. !
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
the front of the vehicle (Y page 117).

front compartment on the passenger side. Checking brake fluid level
X
Perform a visual check of the brake fluid
reservoir 0002.
The brake fluid level is correct when it
is between the minimum mark and the
maximum mark.
R If the brake fluid level has fallen
slightly below the minimum mark,
drive to an authorized electric drive

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 drivin gonroads
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 210).
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
otherwise 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
vehicles behind you. G
WARNING
The vehicle’s handling changes when
driving 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
requirements 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 vehicle. Driving instructions
Drinking and driving
G
WARNING
Do not drink alcohol or take drugs and drive
or allow anyone to drive who has been
drinking alcohol or taking drugs. Even a
small amount of alcohol or drugs can affect
your reflexes, perceptions and judgment.
The possibility of a serious or even fatal
accident are greatly increased when you
drink or take drugs and drive. Pedals
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
pedals still have sufficient clearance.
During sudden acceleration or braking
maneuvers, the objects could get caught
between or beneath the pedals and restrict
your ability to brake or accelerate. This
could lead to accidents and/or injury. Power assistance

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

not covered by the smart Limited
Warranty.
Tire speed rating
Regardless of the tire speed rating, local
speed limits should be obeyed. Use prudent
driving speeds appropriate to prevailing
conditions. G
WARNING
Even when permitted by law, never operate
a vehicle at speeds greater than the
maximum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire
failure, causing loss of vehicle control and
possibly resulting in an accident and/or
personal injury and possible death, for you
and for others.
Make sure your tires have the required tire
speed rating as specified for your vehicle
in the “Technical data section”
(Y page 210), for example when purchasing
new tires.
For information on how to identify the tire
speed rating on a tire’s sidewall, see “Tire
size designation, load and speed rating”
(Y page 134).
If you are uncertain about the correct
reading of the information given on a
tire’s sidewall, any authorized electric
drive smart center will be glad to assist
you.
i For information on speed ratings for
winter tires, see “All-seaso nand winter
tires” (Y page 135). Winter driving instructions
The most important rule for slippery or icy
roads is to drive sensibly and to avoid
abrupt acceleration, braking and steering
maneuvers. For information on driving with snow
chains*, see “Snow chains*” (Y
page 140).
Road salts and chemicals can adversely
affect braking efficiency. Increased pedal
force may becom enecessary to produce the
normal braking effect.
Depressing the brake pedal periodically
when traveling at length on salt-strewn
roads can bring road-salt-impaired
braking efficiency back to normal.
If the vehicle is parked after being driven
on salt-treated roads, the braking
efficiency should be tested as soon as
possible after driving is resumed. G
WARNING
Make sure not to endanger any other road
users when carrying out these braking
maneuvers. G
WARNING
The outside temperature display is not
designed to serve as an ice-warning device
and is therefore unsuitable for that
purpose. Indicated temperatures just
above the freezing point do not guarantee
that the road surface is free of ice.
For more information, see “Winter driving”
(Y page 140). Standing water
Do not drive through flooded areas or water
of unknown depth. Before driving through
water, determine its depth. Never
accelerate before driving into water.
If you must drive through standing water,
