Rims and tires
Notes

!

Only use tires which have been tested

and approved by smart. Tires approved by

smart are developed to provide best pos-

sible performance in conjunction with

the driving safety systems on your vehi-

cle such as the ABS or the ESP

®

.

covered by the smart Limited Warranty.

!

Using tires other than those approved

by smart can have detrimental effects,

such as

R

poor handling characteristics

R

increased noise

R

increased energy consumption

Moreover, tires and rims not approved by

smart may, under load, exhibit dimen-

sional variations and different tire

deformation characteristics that could

cause them to come into contact with the

vehicle body or axle parts. Damage to the

tires or the vehicle may be the result.

i

Further information on tires and rims

is available at any authorized electric

drive smart center. A placard with the

recommended tire inflation pressure is

located on the driver’s door B‑pillar.
The tire inflation pressure should be

checked regularly and should only be

adjusted on cold tires. Follow tire man-

ufacturer’s maintenance recommenda-

tion included with vehicle.

Mobility

Your vehicle is equipped with a tire repair

kit (

Y

page 187). In case of a flat tire, it

enables you to drive to the nearest author-

ized electric drive smart center on the

sealed tire.

If the tire is damaged too severely for the

tire sealant to provide a reliable tire

repair:

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.

Only brake fluid approved by smart is rec-

ommended. Any authorized electric drive

smart center will provide you with addi-

tional information.

WARNING

Windshield washer concentrate is highly

Coolants

The battery and drive system coolant is a

mixture of water and anticorrosion/anti-

freeze, which provides:

R

Corrosion protection

R

Freeze protection

R

Boiling protection (by increasing the

boiling point)

The cooling system was filled at the factory

with a coolant providing freeze protection

to approximately -35¦ (-37¥) and corro-

sion protection.

!

Add premixed coolant solution only.

Adding water and MB 325.0 Anticorro-

sion/Antifreeze separately from each

other, could cause drive system damage

not covered by the smart Limited War-

ranty.

If the antifreeze mixture is effective to

-35¦ (-37¥), the boiling point of the

coolant in the pressurized cooling system

is reached at approximately 266¦ (130¥ ).
The coolant solution must be used year

round, even in countries which have high

temperatures to provide the necessary cor-

rosion protection and increase boil‑over

protection. Refer to Maintenance/ Service

Booklet for replacement interval.
Coolant system design and coolant used

determine the replacement interval. The

replacement interval published in the

Maintenance booklet is only applicable if

MB 325.0 Anticorrosion/Antifreeze solu-

tion or other smart approved products of

equal specification are used to renew the

coolant concentration or bring it back up

to the proper level.

For information on other smart approved

products of equal specification, contact an

authorized electric drive smart center.
To provide important corrosion protec-

tion, the solution must be at least 50% anti-

corrosion/antifreeze (equivalent to freeze

protection to approximately -35¦

[-37¥]).
If you use a solution that is more than 55%

anticorrosion/antifreeze (freeze protec-

tion to approximately -49 ¦ [(-45¥]), the

drive system and battery temperature will

increase due to the lower heat transfer

capability of the solution. Therefore, do

not use more than this amount of anticor-

rosion/antifreeze.
If the coolant level is low, water and

MB 325.0 Anticorrosion/Antifreeze should

be used to bring it up to the proper level

(have cooling system checked for signs of

leakage). Please make sure the mixture is

in accordance with label instructions.
Always use anticorrosion/antifreeze that

has been approved by smart. For informa-

tion contact an authorized electric drive

smart center.
The water in the cooling system must meet

minimum requirements, which are usually

satisfied by normal drinking water.
If you are not sure about the water quality,

consult an authorized electric drive smart

center.
