Smart fortwo coupe and smart fortwo cabriolet electric drive (2015). Instruction — part 9
Always replace rims and tires with the same
designation, manufacturer and type as
shown on the original part.
G
WARNING
Do not overload the tires by exceeding the
specified load limit as indicated on the
Tire and Loading Information placard on
the driver’s door B‑pillar. Overloading the
tires can overheat them, possibly causing a
blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.
Tire load rating A is a numerical code
associated with the maximum load a tire
can support.
For example, a load rating of 91 corre-
sponds to a maximum load of 1356 lbs
(615 kg) the tire is designed to support.
See also “Maximum tire load” (
Y
page 136)
where the maximum load associated with
the load index is indicated in kilograms
and lbs.
For additional information on tire load
rating, see “Load identification”
(
Y
page 142).
Tire speed rating
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 fail-
ure, causing loss of vehicle control and
possibly resulting in an accident and/or
personal injury and possible death, for you
and for others.
Regardless of the tire speed rating, local
speed limits should be obeyed. Use prudent
driving speeds appropriate to prevailing
conditions.
Tire speed rating B indicates the
approved maximum speed for the tire.

Winter tires
G
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 i on 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
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 ped-
als 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
G
WARNING
With the drive system inactive, 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. Adapt your driving
accordingly.
Brakes
G
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 47).
!
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.

-------------------------------------------------------------------------------------------------------------------------------------------------------------
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.

R
Have all maintenance work performed at
the intervals specified in the Mainte-
nance Booklet and as required by the
Maintenance System. Contact an author-
ized electric drive smart center.
Energy consumption is also increased by
driving in stop-and-go traffic, on short
trips, and in hilly areas.
Tires
G
WARNING
If you feel a sudden significant vibration
or ride disturbance, or you suspect that
possible damage to your vehicle has occur-
red, you should turn on the hazard warning
flashers, carefully slow down, and drive
with caution to an area which is a safe dis-
tance from the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have the vehicle towed to the
nearest smart center or tire dealer for
repairs.
Treadwear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and
become visible at a tread depth of approx-
imately
1
/
16
in (1.6 mm), at which point the
tire is considered worn and should be
replaced.
The treadwear indicator appears as a solid
band across the tread.
G
WARNING
Although the applicable federal motor
vehicle safety laws consider a tire to be
worn when the treadwear indicators (TWI)
become visible at approximately
1
/
16
in
(1.6 mm), we recommend that you do not allow
your tires to wear down to that level. As
tread depth approaches
1
/
8
in (3 mm), the
adhesion properties on a wet road are
sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction var-
ies widely.
Specified tire inflation pressures must be
maintained. This applies particularly if
the tires are subject to high loads (e.g.
high speeds, heavy loads, high ambient
temperatures).
G
WARNING
Do not drive with a flat tire. A flat tire will
affect your ability to steer or brake and may
cause you to lose control of the vehicle.
Continued driving with a flat tire or driv-
ing at high speed with a flat tire will cause
excessive heat build-up and possibly a
fire.
For more information, see “Tires and
wheels” (
Y
page 127).
Hydroplaning
Depending on the depth of the water layer
on the road, hydroplaning may occur
resulting in a loss of control, even at low
speeds and with new tires. Reduce vehicle
speed, avoid track grooves in the road and
apply brakes cautiously when it is raining.
Tire traction
The safe speed on a wet, snow covered or icy
road is always lower than on a dry road.
You should pay particular attention to the
condition of the road whenever the outside
temperatures are close to the freezing
point.
G
WARNING
If ice has formed on the road, tire traction
will be substantially reduced. Under such
weather conditions, drive, steer and brake
with extreme caution.
smart recommends winter tires (

in (4 mm) on all four wheels for
the winter season to ensure normal bal-
anced handling characteristics. On packed
snow, they can reduce your stopping dis-
tance compared to summer tires.
Stopping distance, however, is still con-
siderably greater than when the road is not
covered with snow or ice. Exercise appro-
priate caution.
!
Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces. Otherwise, the
drivetrain could be damaged, which is
not covered by the smart Limited War-
ranty.
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 fail-
ure, 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 216), 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 140).
If you are uncertain about the correct read-
ing 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-season and winter
tires” (
Y
page 141).
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 146).
Road salts and chemicals can adversely
affect braking efficiency. Increased pedal
force may become necessary to produce the
normal braking effect.
Depressing the brake pedal periodically
when traveling at length on salt-strewn
roads can bring road-salt-impaired brak-
ing efficiency back to normal.
If the vehicle is parked after being driven
on salt-treated roads, the braking effi-
ciency 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 pur-
pose. Indicated temperatures just above
the freezing point do not guarantee that the
road surface is free of ice.

WARNING
Always fasten items being carried as
securely as possible.
In an accident, during hard braking or sud-
den maneuvers, loose items thrown around
inside the vehicle may injure vehicle
occupants.

if road, weather and traffic condi-
tions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approx-
imately 14 m) every second.
Telephones and two-way radios
G
WARNING
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e.
without being connected to an external
antenna) from inside the vehicle while the
drive system is switched on. Doing so could
lead to a malfunction of the vehicle’s elec-
tronic system, possibly resulting in an
accident and/or serious personal injury.
Radio transmitters, such as a mobile phone
or a citizens band unit should only be used
inside the vehicle if they are connected to
an antenna that is installed on the outside
of the vehicle.
Refer to the radio transmitter operation
instructions regarding use of an external
antenna.
Coolant temperature
During severe operating conditions and
stop-and-go city traffic, the coolant tem-
perature may rise.
!
Excessive coolant temperature causes
the red coolant temperature warning
lamp ? in the instrument cluster to
come on.
The drive system should not be operated
with the red coolant temperature warn-
ing lamp ? illuminated. Doing so may
cause serious damage to the drive system
and the high-voltage battery, which is
not covered by the smart Limited War-
ranty.

Driving abroad
Abroad, there is an extensive smart service
network at your disposal. If you plan to
drive into areas which are not listed in the
index of your smart center directory, you
should request pertinent information from
an authorized electric drive smart center.
Keep in mind, however, that due to the tech-
nical requirements of the smart fortwo
electric drive and its high-voltage power
systems, the vehicle should be serviced
only at an authorized electric drive smart
center.
If you plan to operate your vehicle in for-
eign countries, please be aware that:
R
Service facilities or replacement parts
may not be readily available.
R
The AC power sockets in some countries,
especially overseas, require different
plugs on the charging cable.
R
Charging stations may not be available.
Symmetrical low beams
i
If you drive in countries where vehi-
cles drive on the other side of the road
than the country in which the vehicle is
registered, you must have the headlamps
modified for symmetrical low beams.
Relevant information can be obtained at
any authorized electric drive smart cen-
ter.
Vehicle care
Care tips
Regular and proper care will help to main-
tain the value of your vehicle. The best way
to protect your vehicle from harmful envi-
ronmental influences is to wash it and use
protective treatments regularly.
smart recommends that you care for the
paintwork at least twice a year (e.g. in the
spring and autumn).
G
WARNING
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the par-
ticular container. Always open your vehi-
cle’s doors or windows when cleaning the
inside.
Never use fluids or solvents that are not
designed for cleaning your vehicle.
Always lock away cleaning products and
keep them out of reach of children.
!
Follow the care tips. Wash your vehicle
preferably by hand.
While in operation or even while parked,
your vehicle is subjected to varying exter-
nal influences, which left unchecked can
attack the paint as well as the vehicle
underbody and lead to permanent damage.
Such damage is caused not only by extreme
and varying climatic conditions, but also
by:
R
Air pollution
R
Road salt
R
Tar
R
Gravel and stone chipping
To avoid paint damage, you should imme-
diately remove:
R
Insects
R
Bird droppings
R
Tree sap, etc.
R
Grease and oil
R
Brake fluid
R
Coolant
R
Fuel
R
Tar spots

Failure to remove such dirt immedi-
ately can cause damage to the paint or the

soft top fabric*. Environmental influen-
ces are not covered by the smart Limited
Warranty.
Frequent washing reduces and/or elimi-
nates the aggressiveness and potency of the
above adverse influences.
More frequent washings are necessary to
deal with unfavorable conditions:
R
near the ocean
R
in industrial areas (smoke, exhaust
emissions)
R
during winter operation
You should check your vehicle from time to
time for stone chipping or other damage.
Any damage should be repaired as soon as
possible to prevent corrosion.
In doing so, do not neglect the underbody of
the vehicle. A prerequisite for a thorough
check is a washing of the underbody fol-
lowed by a thorough inspection. Damaged
areas need to be re-undercoated.
Your vehicle has been treated at the factory
with a wax-base rustproofing in the body
cavities which will last for the lifetime of
the vehicle. Post-production treatment is
neither necessary nor recommended by
smart because of the possibility of incom-
patibility between materials used in the
production process and others applied
later.
We have selected vehicle-care products
and compiled recommendations which are
specially matched to our vehicles and
which always reflect the latest technology.
You can obtain smart approved vehicle-
care products at an authorized electric
drive smart center.
Scratches, corrosive deposits, corrosion
or damage due to negligent or incorrect
care cannot always be removed or repaired
with the vehicle-care products recommen-
ded here. In such cases it is best to seek aid
at an authorized electric drive smart cen-
ter.
The following topics deal with the cleaning
and care of your vehicle and give important
“how-to” information as well as references
to smart approved vehicle-care products.
