Index

The traction grades, from highest to low-
est, are AA, A, B, and C. Those grades rep-
resent the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perform-
ance.
Temperature G
WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive load-
ing, either separately or in combination,
can cause excessive heat build-up and pos-
sible tire failure.
The temperature grades are A (the highest),
B, and C, representing the tire’s resistance
to the generation of heat and its ability to
dissipate heat when tested under control-
led conditions on a specified indoor lab-
oratory test wheel. Sustained high temper-
ature can cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to sudden
tire failure. The grade C corresponds to a
level of performance which all passenger
car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades B
and A represent higher levels of perform-
ance on the laboratory test wheel than the
minimum required by law. Rotating tires
G
WARNING
Do not rotate front and rear wheels as they
have different dimensions, e.g. rim size,
wheel offset etc. Otherwise, the handling
can be affected and you could endanger
yourself and others. Thoroughly clean the mounting face of the
wheels and brake discs, i.e. the inner side
of the wheels/tires each time the wheels/
tires are changed. Check for and ensure
proper tire inflation pressure. G
WARNING
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
81 lb‑ft (110 Nm).
Only use genuine smart wheel bolts speci-
fied for your vehicle’s rims.
For information on wheel change, see “Flat
tire” (Y page 187). Tire labeling
Besides tire name (sales designation) and
manufacturer name, a number of markings
can be found on a tire.
Following are some explanations for the
markings on your vehicle’s tires: 0043

WARNING
After changing a tire, contact an author-
ized electric drive smart center to make
sure the bolts holding the wheel to the car
are tight enough. Otherwise, the wheels
could come off. Each bolt should be tight-
ened to a torque of 81 lb‑ft (110 Nm). Sealing a tire (Version 2)
X Take the tire repair kit from the
passenger footwell (Y page 160).X
Take electrical plug 0087and filler hose
0084 from the bottom of the electric air
pump housing.
X Engage the yellow plug of filler hose 0084
in the opening in yellow closure cap 0083.X

iliary power outlet ( Ypage 110).
X Insert the key in the starter switch and
turn it to position 1.
i The vehicle’s 12‑volt battery is drained
by use of the electric air pump. You
should therefore keep the drive system
running while inflating the tire.
X Press ONon electric air pump switch 0085.
The electric air pump is switched on and
inflates the tire.
i First, the sealant is pumped into the
tire. The pressure may briefly increase
to a high value. This is normal and not an
indication of a malfunction. Do not
switch off the electric air pump.
X Let the electric air pump inflate the tire
for a maximum of ten minutes.
The pressure gauge must display at least
200 kpa (2.0 bar, 29 psi).
! Do not operate the electric air pump
longer than ten minutes without inter-
ruption. Otherwise it may overheat. 192

sure: Press deflate button 006C. Recheck
the tire inflation pressure with the
electric air pump’s pressure gauge
006D.
X When the tire inflation pressure is cor-
rect, unscrew the end of filler hose 0085
from tire valve 006B.
X Screw the valve cap onto the tire valve. X

! The manufacturer is unable to guaran-
tee that all tire punctures can be
repaired with the tire repair kit, in par-
ticular cuts or perforations larger than
approximately 0.16 in (4 mm) or away from
the tire’s tread. The manufacturer is not
liable for damage sustained through
improper use of the tire repair kit. G
WARNING
Follow recommended tire inflation pres-
sures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and energy con-
sumption of the vehicle, and are more
likely to fail from being overheated.
Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are more
likely to become punctured or damaged by
road debris, potholes etc.
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.
